Behind on the Rent

(MFf, Ff inc (mother-daughter), anal, ws)
(this is one of Puppy's stories)

Her name was Kathy.  33 years old, chubby, dirty-blond hair.  I met Kathy when I visited the restaurant where she worked as a part-time waitress.  I'm a relatively well-off guy, and I dress like it.  Kathy was attracted to my looks, my self-confidence, my deep voice.  She flirted with me, we exchanged numbers, and that evening I found myself taking her out to a nice dinner, then going back to her place for sex.  It's particularly nice to bed a woman when she is really into it, excited by the novelty of a new man, excited by dating above her social class.  Her clothes came off so eagerly, there was real enthusiasm in her blow job, and she was so wet when I moved onto her plush, plump body and sank into her fiery depths.  That first night, I lost count of her orgasms, and I came a couple times myself, in her mouth and in her pussy.  Cuddling post-sex was nice, but then she reluctantly asked me to go home, because she'd find it awkward in the morning, to explain a man in her bed to her daughter.

Ah, her daughter.  Kathy and I became a steady thing, so I eventually met her daughter, Kaitlyn.  14 years old, chubby like her mom, a freshman at the local high school.  She was quiet, a little shy around me.  She liked reading books, and she played videogames for hours.  She usually stayed in her room, especially when I was over at their apartment.

This went on for some months.  Eventually, Kathy and I started seeing less of each other.  I started dating a new woman, Susan.  Susan was 40 years old, smart, sophisticated, independent.  She had a realty business and drove a Mercedes.  Our dinner dates were full of intellectual conversation.  We liked spending time together, like going around town, even shopping with her was fun.  The only catch was that Susan wasn't particularly sexual.  She liked kissing, and she liked it well enough when I went down on her, but intercourse was brief and mechanical, and she had zero interest in my cock going anywhere near her mouth.

So, I still occasionally saw Kathy, basically as a booty call, preceded by dinner.

Then, Kathy's life took a turn for the worse.  She got behind on her rent, and lost her apartment.  She scrambled for another place to live, and knowing that I managed some rental properties, she asked me.  I fast-tracked Kathy's application, told my staff to ignore her dismal credit rating.  I paid for a moving truck.  She and her daughter had a place to live again, a smaller apartment, in my cheapest property.  She scraped together her first month's rent, and I waived the deposit.  I was now their landlord.

Everything seemed fine until one month later.  I went by their apartment on Saturday morning.  Kathy let me in.  She was wearing a loose robe, looking like she just rolled out of bed.  There was breakfast still on the breakfast table, and the TV was going.  Kathy went to the sofa, and I sat in a chair across from her.  She turned down the TV and gave me her full attention.

"Your rent was due yesterday, Kathy."  I gave her a serious look.

She nodded.  "Yeah.  I'm totally going to have it for you.  Next week?"

I sighed.  "That's not how this works, Kathy.  You'll need to find the money."

She looked worried.  "I thought... I thought we had a relationship?  I mean, I know I'm not your girlfriend, but... I do things for you."

I smiled.  "Yes, you do.  Are you really comfortable with that?  Let's get this out in the open.  Trading sex for rent?  I mean, you've probably never traded sex for money before."

She frowned.  "I've never done that outright, no.  But I like you, Mike.  And you like me.  And sex with you feels good.  So... if you don't mind getting part of your rent in sex... I think I'm OK with that."

I nodded.  "So, we make it explicit.  You're willing to become my sex worker."

She nodded and smiled.

"I'm glad that you're comfortable with that," I said.  "But you have to admit, I am holding all the cards here.  It is, as they say, an imbalanced power relationship.  What if I said I wanted more?  Like, I wanted to fuck you right out there in public, for everyone to see?"

"You'd get in trouble."

"OK, what if I asked for ridiculous, kinky stuff?  Like, if I wanted to watch you fuck yourself with a cucumber?"

She laughed.  "For the rent?  Sure, I can do it with a cucumber.  As long as you take it out of the fridge for a while, so it's not too cold."

"OK, how about anal sex?  Anal sex, or you're out on the street?  Your only options would be to do it, or say no and leave."

Her smile faded.  "I... I guess I would learn to enjoy it."

"OK.  How about Kaitlyn?"

There was a long pause. Kathy looked at me in shock.  "You... you want to have sex with my daughter?"

"Let's say, not full sex.  Hypothetically, just fooling around with her.  Like, oral sex."

"That's still statutory rape!"

"For fuck's sake, Kathy.  I'm only suggesting that your daughter suck my cock.  How old were you when you first gave head?"

She paused and nodded.  "OK, I was 15.  But Kaitlyn..."

"She's already fooled around with boys.  You told me that.  Look, I'll make a perfectly clear proposal.  I presume Kaitlyn's still a virgin, she stays a virgin.  Her panties stay on.  I don't have any interest in fucking her, young teenagers are too inexperienced and usually don't know how to enjoy intercourse yet.  So, just oral.  All I require is that I come in her mouth."

Kathy sat there in stunned silence for a minute.  "You're serious."

"Yes.  I don't care if she gives me a full blow job, or hand job, or talks dirty, or however she does it, or if you help her.  All I require is that the head of my cock is inside her mouth when I ejaculate, and that she swallows.  Did you swallow, when you were 15?"

She shook her head.  "No.  I spit.  I didn't swallow until I was 19 and I met Kaitlyn's father.  I was crazy in love with him and I'd do anything."  She stared at me.  "Why don't you just come in my mouth?  You like my blow jobs.  I swallow for you."

I shook my head.  "Sorry, dear, but to put it bluntly, I can come in your mouth any time.  Your 14-year-old daughter is what I'm asking for.  I want the kinky thrill of doing it in her innocent young mouth.  I want to watch her cute young face as she swallows my load."

Kathy shook her head.  "That is so fucked up!  What about her?  Does she get a choice?"

"Of course she does.  Neither of us is going to force her.  If your daughter's acceptance of the arrangement is your only objection, just ask her.  I imagine she's in her room?  You could go explain the situation to her.  Tell her it's for the rent, for having a place to live.  See what she says."

"That's not my only objection!  She's a human being, Mike.  You're talking about treating her as nothing more than a sex object.  I am her mother, I worry about what effect that will have on her.  She's more than just a hole for your perverted fantasies."

I sighed.  "I know that, Kathy.  She's a bright young woman, with a possibly bright future ahead of her.  But look at it this way, she won't have much of a bright future if you're evicted tomorrow and you're out on the street."  I paused.  "Go ask her."

Kathy frowned and shook her head, but she got up and went down the hall to Kaitlyn's room, closing the door behind her.  I went to their fridge and helped myself to a beer, then sat back down to wait.  In just a few minutes, they both came out of Kaitlyn's room and came over to sit on the sofa in front of me.  Kathy was frowning, but Kaitlyn, still in pajamas, was smiling.

"I'll do it!" said Kaitlyn.

"Great," I said.  "So... have you done it before?"

"Not really.  I've done it for guys with my hand.  I've seen boys shoot their stuff.  It sounds gross to let you do it my mouth, but there are a lot of worse things me or Mom might have to do, to make our rent."

"I couldn't talk her out of it," sighed Kathy.

"That's an impressively grown-up perspective to take, Kaitlyn," I said honestly.

"I'm 14!  I'm not a kid.  And I'm not going to let any random creep do it to me.  I know you, Mike.  You've always treated my Mom really nice.  If this weird sex thing is what you want, and we get to stay in this apartment, I'll do it."

"Great," I said, standing up and unzipping my pants.  "How about now?"

"Jesus Christ," muttered Kathy.

"Sure, now," said Kaitlyn, nodding but looking a little apprehensive.

"Shouldn't I leave the room for this?" asked Kathy.

"Hell, no," I said.  "Remember, Kathy, your job is to make sure I come in her mouth.  Since you're not volunteering to help her, she's going to have to try to do it herself this time.  She's never given head before, she might not get me off.  You need to watch, and you might need to give advice."

"Oh, fuck.  This is fucked up," said Kathy, but she didn't leave.

"So... what do I do?" asked Kaitlyn.

I moved to stand in front of her.  "To start with, just take out my cock.  Get familiar with it.  When you're ready, try sucking on it.  Be careful not to graze me with your teeth."

"Oh. OK."  Kaitlyn was a little timid about actually reaching into my boxer shorts to pull out my erect cock, but once it was out, she barely looked at it before popping the head into her mouth.

"Oh my God," said Kathy, staring intently.

"That's beautiful," I said to Kaitlyn.  "Good girl.  I'm honored to be the first cock in your mouth.  Now, try sucking me in and out a bit.  Just like how you've given hand jobs before, except you're using your mouth to get me off."

For a minute, there was just the soft sound of sucking, Kathy and I watching intently as Kaitlyn practiced.

"Kathy," I said.  "Don't forget.  Your job is to make sure I orgasm."

"How am I supposed to do that?"

"There are lots of things you could do.  But you could start by standing here next to me, and kissing me while she sucks."

"Mike, I don't feel like kissing you.  I'm pretty pissed off about what you're doing to my daughter."

"That's fine.  So come give me an angry kiss.  Sooner or later, you're going to have to relax and accept what's going on.  Your resistance is kinda sexy.  So, come kiss me."

Kathy stood up.  I pulled her to my side, bringing her face to face with me.  She stared into my eyes with a complex blend of emotions, and then we kissed, at first roughly, and then more tenderly.  It felt lovely, my tongue in Kathy's mouth, gently being sucked, as Kaitlyn similarly sucked the head of my cock.

"Tell me you want me to come in her mouth," I suggested, breaking the kiss.

"I don't want you to come in her mouth."

"Yes you do, because it will allow you to stay in your apartment."

"Well, alright.  In that sense, I do want you to come and get this over with."

"Great, let's work with that."  I reached my right hand into the loose folds of her loose robe, slipped my hand into the cup of  her loose bra, and fondled one of her large, floppy tits, finding a nipple with my fingers.  "Let's try this again.  Tell me you want me to come in her mouth.  Ask nicely.  Make it sexy."

"Oh, fuck," muttered Kathy.  "Sure.  Whatever.  You want me to talk dirty about it, that'll get you off?  Do it, Mike."  She paused to kiss me again, deeply.  "Go ahead.  Pretty please?  Fuck my daughter's innocent little mouth and shoot off in it.  Please fill up her young mouth with your cum."

"That's good," I said, reaching down with my left hand to gently run my fingers through Kaitlyn's dirty-blond hair.  I gently grasped her head, encouraging her to take a bit more of my cock, being careful not to press too deep.  I didn't want her gagging.  After she was comfortable with it, I pulled her head off my cock.  "Kaitlyn, how about you?  I'd like to hear you ask for it."

Kaitlyn looked up at me, saliva running down her chin, breathing a little hard.  She was still getting the hang of remembering to breathe with her mouth full.  "Ask... for it?"

"Yes.  Smile at me and tell me you want me to come in your mouth."

"Oh.  OK.  Um."  She managed a weak smile.  "I want you to come in my mouth?"

I smiled.  "Not very convincing, but we'll work on it.  Good enough for now."  I pressed myself up to her lips, and she took me in and resumed sucking.  I went back to kissing Kathy and rolling her nipple between my fingers.

"Is she doing a good job?" asked Kathy, breaking the kiss to whisper in my ear.  "Are you going to give her your tasty cum to drink?"

"I am pretty close," I replied, "but at this rate, her jaw will probably be sore by the time I finally come.  Since this is her first time, I'll make it easy on her."  I gently pulled my cock back.  "Kaitlyn, darling, I'm going to jack off my cock."  I pulled my right hand out of Kathy's clothes, and used it to stroke my erection, right in front of Kaitlyn's face.  "Just keep your mouth available.  When I come, be sure to capture it all, and swallow.  Got it?"

"Yeah.  OK."  Kaitlyn looked up at my face, then back down to my stroking cock.

"Oh, that looks so hot!" said Kathy, in a convincingly lustful tone of voice.  "Masturbate yourself into her mouth!"

Something in the way Kathy said it, pushed me over the edge.  I felt my orgasm beginning, my legs got a little weak.  I adjusted my stroke, pushed the head up to Kaitlyn's lips, she took me in and I started ejaculating.  I managed to look down at her young face, to see the look of surprise, then a scrunched-up look of distaste, and then finally a serious look of resolve as she sucked and swallowed me down.

"Good girl, Kaitlyn!" I said, as I finally stopped spurting, and pulled my cock back, tucking it into my pants.  "You did great!"

"Ewww," she said.

"So we're good for the rent?" asked Kathy.

"Yes.  And I must say, Kathy, you sure know how to talk dirty."

"Men are simple.  I know how to push your buttons."

"You do.  In fact, you can go ahead and stop worrying about paying rent, ever again.  I'll just drop by from time to time, and the two of you can do whatever it takes, to get me to come in Kaitlyn's mouth."

"Time to time?" asked Kathy.

"Yes, not too often.  I mean, I'll still enjoy dinner and sex dates with you on occasion.  I promise not to use Kaitlyn's mouth too often.  Say, once a week or so?  Kaitlyn, can you handle that?"

"Yeah,  I guess so."  She frowned.  "It doesn't taste great.  I'm going to go drink some soda pop to get the taste out."

---------------------------------------------------

I saw my proper girlfriend Susan a couple times that week, which satisfied me in every way but sexual.  On Thursday, I had a date with Kathy.  After dinner, we went back to her place.  There was no sign of Kaitlyn.  Kathy and I talked for a long time, unpacking our feelings about what we did with her daughter the previous weekend.  She told me that Kaitlyn used to have a crush on me, but now had very mixed feelings since I was using her as a sex object.  I told Kathy that just before I orgasmed, I started to believe her dirty talk, that maybe she actually was getting off on the situation.  She denied it, but not very convincingly.  Soon we were in her bedroom undressing, I came once quickly in her mouth, she came once quickly on my fingers, then I fucked her silly through several positions and orgasms before I finally came again.  Kathy is pretty loud during sex, and I knew that Kaitlyn could hear us through the walls of their cheap apartment.

On Friday night, an evening with Susan ended back at her place, with her requesting oral sex, getting off, then apologizing for not being in the mood to return the favor, and me going home alone and sexually frustrated.

By the time I showed up at Kathy's apartment on Saturday morning, I was horny as fuck.

"I assume you're here for the rent?" said Kathy with a wry smile, as she let me in.  "And by rent, I mean my daughter's mouth."

"Yes I am."

Kathy called for her.  Kaitlyn came out of her room, wearing the same pajamas as the week before.  The pajamas were pale blue, with fluffy white cartoon clouds on them.  They were large, to fit on her plump body.  Now, most people in this culture would call Kaitlyn a fat girl.  But my tastes in women run to the plus size, and by my standards, she wasn't that big.  Attractively curvy, yes.  There was weight on her face and her belly, but also sexy weight that sat on her breasts and hips that made her body look much older than 14.

"Mike," said Kaitlyn as she came over and sat across from me.  "We can do the thing, but... I want to say something first."

"Sure," I smiled.  Her apprehension was adorable.  "Go ahead."

"Mom says you're treating me like a sex object.  But I wish you would treat me nicer than that.  I mean, you can still do the thing in my mouth.  But you could at least kiss me and stuff, first.  The boys I've fooled around with did at least that."

I smiled.  "Sure, darling.  I like you.  You're a beautiful young woman.  I'd be happy to kiss you or make out with you or anything you'd like.  In fact, that would turn me on even more, which would help you accomplish your goal of getting me off."

"You think I'm beautiful?" she said, quietly, clearly surprised.

"I do, and I am completely honest."

She smiled softly, and approached me where I sat on the sofa.  I took her hands, and drew her to me.  Our first kiss was awkward, but eventually she relaxed a bit.  I pulled her to me, and she giggled as she moved to sit in my lap, facing me.  I don't know if you've ever had a 200+ pound girl sit on your lap, but it's a major thing; thankfully, the sofa had a lot of give, and her legs on either side of me took some of the weight.  We kissed and kissed.  Her tongue came out shyly to meet mine.  My hands went around her body.

"Do you want to play with my tits?" she asked.  "Boys usually like that."

"I'd love to," I said.  "Does it feel good for you, when boys do that?"

She pulled  her pajama top off.  She was braless, and even at 14 the weight of her chubby breasts was pulling them downward.  She shrugged.  "I don't know.  Kinda.  I mean, touching my nipples can feel kinda sexy, sometimes."

I played with her nipples with my fingers, then alternated kisses with nipple sucks, trying various things with my tongue to gauge her reaction.  Mostly, she giggled.

"This is fun, but you're squishing me," I said.

"Oh!  OK, let me suck on you now."

She got off my lap, and knelt topless on the carpet in front of me.  I helped her fish out my nearly-hard cock.  She launched right into a clumsy, amateur blowjob.  I had to tell her to slow down, to watch out for her teeth.  More sucking, less head bobbing.

"I see you're getting on just fine," said Kathy, coming into the living room, observing the blowjob in progress.

"I need your help," I said.  "She's only just learning to suck cock, so it's going to take more to get me off.  Strip naked."

She stared at me in surprise.  "Right here... in the living room... in front of my daughter?"

"It's nothing I haven't seen before, and if your daughter isn't already familiar, I'm sure she doesn't care what naked adult women look like.  Strip, then sit in that chair across from us."

"OK.  Fine."  She removed her robe, then her bra and panties, then she sat her pleasantly plump naked body down facing us.

"Spread your legs," I instructed.  "Touch yourself, as you talk dirty about what we're doing."

"You kinky fucker," she said.  She spread her legs.  "You want to watch me masturbate while my daughter sucks your cock?"

"Exactly.  Remember, I like to hear you asking and encouraging me to come in her mouth."

"Yeah, yeah, I remember.  This is still fucked up."  She sighed, then I saw her hands start moving between her legs.  "I see you already got her top off.  Did you enjoy playing with her cute little teenage tits?"

"I did, and they aren't that little.  She offered them to me, and I wasn't going to turn her down.  I tried sucking her nipples, but it didn't do much for her.  Not like you, Kathy, you nipple slut."

"You're damn right I'm a nipple slut," she said, using her free hand to roll one of her own nipples between her fingers.  "How does her sweet little mouth feel on your cock?"

I put one hand on Kaitlyn's head, gently using it to speed up her sucking a bit.  "It feels great.  She's got potential.  She could grow up to be a champion cocksucker, like you."

"Good."  Kathy's hand was moving a little quicker now, between her legs.  "I... I really, really want you to bust your nut in her mouth, and give her a big mouthful of sperm to swallow."

"Your dirty-talking game is strong," I said.  "My girlfriend left me high and dry last night, so my balls are probably really full right now."

"Good!  Drown her with it!"  Kathy was doing a very good impression of being turned on.  Or, maybe she actually was.  "Too bad she's so young, she doesn't know how to take you down her throat yet, like I can."

"True," I agreed, "but that's fine.  I don't want to come down her throat.  I want to fill up her mouth, so she can experience the full taste of my cum."

"That's so true.  You're going to train her to love the taste, aren't you?"

"Maybe.  I don't know what's sexier, training her to love the taste, or training her to crave the experience of a mouthful of cum, even when she doesn't like the taste."

"Mmmm, you're right."

Kaitlyn pulled her head up.  "I'm... I'm sorry.  I'm getting sore.  My jaw is getting tired."

"That's no problem, darling," I said.  "I only have to come in your mouth.  You don't have to suck me to make that happen.  Your mother can suck me.  Come here, Kathy.  Suck me until I'm about to blow, then I'll blast it in Kaitlyn's mouth."

"You kinky fucker!" said Kathy.  "OK, damn it.  I can't believe you're making me stop."  She got out of the chair and approached us.

"You don't have to stop masturbating.  I've seen you do it while you're on your knees sucking me."

She grunted her acknowledgment, still completely naked, as she got on her knees next to her daughter.  Kathy dove onto my cock, swallowing it.  Kaitlyn looked on in amazement, just inches away.  I knew from the position of Kathy's arm that she was indeed reaching under herself to masturbate while she sucked.

"Wow.... she's good at that!" said Kaitlyn, clearly surprised as she observed, for the first time, the act of her mother giving head.

"Your mother is a sexual dynamo," I said, bending forward slightly, so that I could reach my left hand down to grasp one of Kaitlyn's breasts, my right hand down to grasp one of Kathy's.  It was the first time I had a hand, sexually, on a mother and daughter at the same time.  It was thrilling.  Kathy's head bobbed expertly, her lips and tongue playing with wetness and friction.

"Um... I'm supposed to say I want it, right?" said Kaitlyn, "so... um, please don't come in my mom's mouth.  Please do it mine!  I want to taste it!  I am so hungry for your cum."

"Good work," I encouraged,  "You'll develop skills in talking dirty like that.  In the meantime, notice how your mom's mouth doesn't take in my whole cock?  There's a bit of shaft exposed.  Wrap your hand around that."

"Oh, wow," said Kaitlyn, grasping the base of my cock, slippery with her mother's saliva.  Her fingers gave me a squeeze.  That was sexy, but even more sexy is that I could tell, from the familiar way Kathy's breathing shifted, that she was giving herself a small orgasm as she sucked.

"Oh, fuck!" I gasped, feeling my balls clench.  "Now!"

Quickly, my cock was passed to Kaitlyn's mouth.  She made a respectable suction lock on it, as I came hard.  I didn't notice as much cringing, this time, as she methodically swallowed.  We both watched as she gradually drank it all, then slowly let my cock slip from her mouth.

"Well, that's our rent paid," said Kathy, getting up to find her bra and panties.  "I've got dishes to do."  She headed back to the kitchen.

"That was a lot of cum," said Kaitlyn.  "Are you going to leave now?"  Something in the tone of her voice made it clear she didn't want me to.

"I'll tell you what," I said.  "I'd like you to feel less like a sex object.  Cuddling after sex can be nice.  Would you like to come up here and cuddle with me?"

"Yeah."  She smiled, then scrambled up.  I found myself putting my arms around a wiggling, smiling, topless plump teenage girl.  We kissed.  There was just a hint of cum taste on her lips, not too bad.  I casually played with her tits, and I found myself starting to grow hard again.  She really, really liked kissing.

"So you've seen your mom masturbate now," I said, "and you've seen me do it, right into your mouth.  I know most girls are shy about admitting it, but you masturbate, don't you?"

"Yeah."  She smiled shyly.  "Actually I didn't get a good look at Mom doing it.  She was behind me and I had my mouth full.  But yeah, I do it sometimes too."

I slipped one hand down her belly, resting it on her thighs.  "Would you like me to touch your pussy?"

She looked into my eyes, suddenly serious.  "That depends.  Are you doing it because you want me to feel good?  Or are you touching  my private parts because, like, it's a power trip, I'm your sex object?"

"Both, I think," I admitted, "But, I do think you'll like it."

"OK, then."  She pushed her pajama bottoms down to her knees, and spread her legs wide to give me access.  A chubby girl needs a very wide spread to fit a hand between those thighs.  We shuffled on the sofa until I had good access, my hand slipping into her panties and starting with gently caresses to the outside of her vulva.  Very gently, I explored until my middle finger found some wetness, then I used that tease her labia apart, to find her clit.

"Oooooh," she sighed.  "That's nice."

I spent several lovely minutes just patiently working on her clit, with occasional forays to explore around her inner and outer folds.  She responded nicely.

"I'm glad you like it," I said, "but playing with you is also getting me extremely hard again.  We can keep going and see if you'll come.  But either way, I'm going to want to get off again."

"Well, you said you're not going to take my virginity?"

"That's right, I'm not."

"Um... I guess you could do it my mouth again?"

"That'd be nice, but I have a better idea.  We could call your mom in here, and I could fuck her right here on the living room floor.  You could masturbate while you watch us fuck."

"Oh!"  Her pussy gave little convulsion.  Clearly, she was aroused and not thinking straight.  "Uh, but, um, would she do that?  I mean, let me watch?"

"She won't turn me down.  I'm your landlord," I said smiling.  "Kathy!"

A minute later Kathy came into the living room, still in bra and panties.  "What?  Oh."  She saw where my hand was.  "Well, I see you've moved on to molesting every part of my underage daughter."

"She's close to coming on my fingers," I said.  "But I'm also ready to go again.  Get naked again, get down on the floor right here, on your hands and knees.  I'm going to fuck you, and she's going to watch."

Kathy stared at me.  "You're serious?"

"Completely serious.  Kaitlyn, tell your mother to do it."  My slippery fingers on Kaitlyn's clit were moving rhythmically.

"Um," sighed Kaitlyn softly.  "Yeah, Mom."

"We already paid the rent," said Kathy.  "I am not your sex slave.  I don't have to do this."

"You'll do it because you like to fuck," I said.  "And because you're already wet from playing with yourself.  And because your daughter is curious about what real sex looks like.  And even though you won't admit it, you have an exhibitionist streak.  And, because I'm hard and ready for you."  I gestured toward my erection.  "Strip.  Get down on all fours."

"Oh, fuck, this is wrong," muttered Kathy, but she was already unsnapping her bra.  I took one of Kaitlyn's hands, and put it where my hand had been, on her pussy.  I got up and helped pushed Kathy's panties off, then guided her down to her hands and knees on the soft carpet.  I got in front of her, and she accepted my cock in her mouth.  Slowly, I thrust into it.

"Watch, Kaitlyn," I said.  Kaitlyn was staring at us, in fascination, her hand moving slightly.  My hands held Kathy's head, my fingers in her dirty-blonde hair.  "See how I'm fucking your mom's mouth?  She lets me do this whenever I like.  She lets me be in control.  I like your mom as a person, but I really love her as a slut.  She's also really good at this.  It's not easy to get fucked in the mouth, but your mom has skills and experience.  I can even go pretty deep, a little bit into her throat."  I demonstrated, holding myself deep.  "Someday, you could learn to do this too."

"How... how can she breathe?" asked Kaitlyn.

"She can't.  She holds her breath."  I pulled out, and Kathy gasped for air.

"Jesus Christ, just fuck me already," muttered Kathy.

I moved around behind Kathy, and sank myself into her pussy.  She moaned.  I grabbed her wide hips, and thrust.  Her big soft plump bottom made a lovely cushion for the strong fuck I gave her.

"Your mom's pussy is excellent," I told Kaitlyn.  "It's big, but she also knows how to squeeze me, so she makes it tight.  And she's completely dripping wet right now.  She's getting off on the embarrassment of letting her own daughter watch her get fucked."

"I am not," muttered Kathy, unconvincingly.

"Normally, I'm fucking her in missionary," I said.  "I'm on top, and my body is slamming into her clit on each thrust, which helps her get off.  When I'm fucking her doggy style like this, her clit isn't getting as much contact.  But your mom is such a sexual dynamo, it doesn't matter.  She can come from fucking at any angle.  That's another thing you could learn to do, someday."  I thrust harder.  "Since you already drained my balls once, I can last a lot longer now.  Look at the way her body shakes and jiggles when she's getting fucked.  I love to watch her body.  She looks sexy, doesn't she?"

Kaitlyn nodded and said "Yeah" quietly.  Her eyes were fixed on us, her hand was moving more quickly between her legs.

I could tell Kathy was trying not to moan, but eventually she gave in and her heavy breathing started to get louder.  There was a cry, then silence, and I felt her pussy gush.

"Your mom just came on my cock," I said.

"Wow!" said Kaitlyn.

I thrust gently for a bit, paying careful attention to the way Kathy's pussy was moving, then started to pick up speed again.  "She can come again, too.  Another thing for you to learn to do, someday."

Kathy was moaning continuously now.  She was past the point of words.  I fucked her through one or two more of her orgasms, before I felt myself getting close.  On the sofa, I heard Kaitlyn make soft noises as her thighs suddenly closed around her hand.

"That's a good girl," I said.  "Come, Kaitlyn.  Come as you watch us fuck!"  It set me off.  I dumped whatever cum I  had left, deep in Kathy's pussy.

Kathy groaned, stumbling forward away from me.  "That's enough!  I'm going to go take a shower."  She grabbed her clothes and left the room.

I went to Kaitlyn on the sofa, sitting beside her.  She smiled at me, and accepted a wet kiss.

"Was that sexy?  Did you like watching?" I asked.

"Yeah," she said softly.

"Touch my cock," I said.  She moved her hand over to me.  "See how it's dripping wet?  That's mostly your mom's orgasmic juices.  Does it seem weird to you, touching it?"

"A little weird, yeah."

I brought her right hand up to my mouth, and kissed and licked her fingers.  "Your hand tastes like your pussy.  It's not bad, it's actually a pretty nice and sexy taste."

She licked her own fingers.  "Yeah.  It's OK.  I'm used to my own taste."

"There's one more thing I'd like you to do for me, today.  You don't have to do it, but I'd find it super sexy.  I want to put my soft cock in your mouth, and I want you to taste your mom on it.  Can you do that for me, or is it too weird?"

She looked at me with surprise.  Still in a big of a glow from her orgasm, she nodded her approval.  I stood up and put my cock at her face.  She regarded it cautiously, before finally taking it in her mouth.

"Good girl!" I said, patting her head as she gently sucked.  "This is going to help you pay the rent.  Sooner or later I'm going to get you and your mom together in bed.  I might be fucking her, then I'll want to do it in your mouth, so it will help if you're comfortable with the taste of her pussy.  Do you think you could do that?  Let me move my cock right from her pussy to your mouth?"

She let me slip from her mouth.  "I... I think that would be OK?"

"Good girl," I said, kissing her, then finding my clothes and leaving.

---------------------------

Of course, my girlfriend Susan knew about my relationship with Kathy.  I'm an honest person, and it's not like I would keep my whereabouts a secret, twice a week.  As far as Susan was concerned, she and I were in love, and Kathy was just someone I had sex with.  She seemed curiously unthreatened by the existence of Kathy in my life.

I did not tell Susan about Kaitlyn, however.  Susan was being sexually un-possessive and understanding, and I appreciated that, but I did not expect that understanding to extend to oral sex with a 14-year-old girl.

-------------------------

The next Saturday, I did not try to put Kathy and Kaitlyn in bed together.  I had a better idea: educate Kaitlyn first.

"Oh, Hi, Mike," said Kathy letting me in the door.  Kaitlyn was already in the living room, on the sofa, in pajamas.  "There's my daughter.  Can you collect your rent with her, or do you need me to participate again, in some messed-up, kinky way?"

"Actually, I don't need your help at all today.  I'd like to take Kaitlyn out on a date, if that's OK.  Might take most of the day."

Kathy stared at me.  "You're 36, Mike.  She's 14.  A date?  In public?  She's obviously young enough to be your daughter."

"Nobody know she's not my daughter, or step-daughter.  It's a big city.  I'll take her to the mall and buy her some things, like any father might."

"I want to go!" said Kaitlyn.  "I want him to buy me things."

"It would be best if you called me Dad out in public, then," I said.

"Wow, that's messed up," said Kathy.  "Act like her dad all day, then bring her home and get your rocks off in her mouth?"

"Pretty much, yes," I admitted.

"Pleeeease?!" said Kaitlyn.

"OK, fine," said Kathy.  "At least I don't have to play any part in it."

"Yay!!" squealed Kaitlyn, dashing off to her room to get dressed to go out.

Kaitlyn and I departed, in my car.  We went to the mall first.  I asked her what she wanted, and she wanted new bras that fit her better.  Like any dad, I waited outside the store until she was ready to purchase, then came in with my credit card.  She squealed with joy and said "Thank you Dad!"  Then I took her over and bought her a new iPhone, the expensive model with the big screen.  She was floored, and delighted.  Then me and my "daughter" had lunch at a fancy restaurant, then we went back to my place.

In my townhouse, we were barely inside the door when she was eagerly kissing me.  I led her to the large walk-in shower, we undressed and showered together.  I got my first good look at her fully naked body, and a good feel of it too, with my hands all over her, and hers all over me.  We toweled off and headed to my big bed, my erection bobbing, watching her plump body wiggle as she walked in front of me.

"Are you going to do it my mouth, now?" she asked with a smile, then added, "Daddy?" and giggled.

"Actually, I have a better idea.  I'd like you to watch some porn with me, and we'll make you come a few times first."

"Sure.  That sounds fun," she said smiling.

I fell onto her, in the bed.  We rolled around kissing and making out for a bit, then I went over the giant laptop by the bedside, and queued up some porn.  I had picked out some appropriate scenes.  Teenage lesbians, first, getting each other off with fingers and tongues.  Threesomes, with a man, a woman, and a teen girl.  Particularly, scenes where the teen girl gets her pussy eaten, visibly orgasms, eats the pussy of the older woman, sucks cock, eats cum.  All during the porn, I was playing with Kaitlyn's young wet virginal pussy, at first with fingers, and then I just went ahead and went down on her.

Apparently, none of the boys she'd fooled around with had given her oral sex.  She loved it immediately.

After she came on my mouth, I opened up a bedside box of vibrators.  The poor girl had never used one before, but she quickly got the idea, trying out several models, and different speeds.  Finally, I started her on cocksucking practice.  She had a vibrator between her legs the entire time, as she spent a good, long time sucking me.  I finally found myself getting close.

"Please come in my mouth now, Daddy," she said, sensing my closeness.

"Are you just saying that because you're supposed to?" I asked.

"Kinda.  Not really.  I mean, I still don't like the taste."  She stroked me gently, aiming my cock at her face.  "But you've been so nice to me.  Whatever you want, I want it too.  You could spank me.  You could take my virginity.  You could make me crawl around and bark like a dog!  I don't care what it is, I'll do it.  I know you like coming in my mouth, so I want it too."  She smiled, pausing to give me a few strong sucks.  "I think I know how to talk about it, like they did in that porn."

"OK," I said smiling.  "Go ahead."

"Please, Daddy?  Would you please dump your cum in my mouth?  I'm thirsty for your cum.  I want to taste it.  I want a whole mouthful!  I want to feel your sperm all around my tongue, I want you to fuck my mouth for your pleasure, I want to swallow it, please?"  Then she resumed sucking.

"OK, my sweet little girl," I said.  "Since you asked so nicely."  I exploded in her mouth.

She looked directly into my eyes the entire time, my cock pulsing, a look of delight on her face, as she savored and swallowed.

"Rent paid," I said, as we cuddled together afterward.

"Oh, Daddy," she said.  "Much more than that.  I... I know I can't be your girlfriend.  But... I wish I could do more to make you happy."

I smiled, caressing her.  "You are already a delight.  But I'll tell you something secret.  I do have a sexual fantasy, a deeper fantasy than coming in the mouth of a cute young woman.  And you could help me fulfill it."

She looked in my eyes, her arms around my body.  "Tell me what it is.  I'll do anything."

I smiled.  "It's not entirely up to you."  I paused.  "You know all that lesbian porn we watched?  Did you find it sexy?"

"Yeah, I did," she admitted.  "Is that what you want?  You want to have sex with me and another girl?  I'd totally do that for you."  She giggled.  "I think that's a really common fantasy for guys, isn't it?"

"Are you sure you'd be OK with it?" I continued.  "You could kiss another female, touch her pussy, give and receive oral sex, make each other come?"

"Sure, I'd try it."  Kaitlyn giggled.  "Especially if she was pretty, like the girls in your porn."

"Good.  Well, that's not exactly my fantasy."  I paused.  "I want to watch you have sex with your mom."

Kaitlyn's mouth opened in astonishment.

"Remember last week," I continued, "when I had you suck my cock clean, after I fucked her?  You were OK with that.  So if you don't mind the taste of her pussy juice, I want to see you suck it, directly from the hole you were born from."

Kaitlyn's mouth finally closed, and she shook her head.  "Wow.  Um.  Well, she'd never go for it."

"What if she would?  Are you saying that you'd do it?"  I caressed her.  "For me?"

"I guess so," she mumbled, looking unsure.  "But... uh... isn't that like, illegal and stuff?  I mean, she's my mom.  Me having sex with her, is like, uh, what do they call it."

"Incest."

"Yeah."

"I don't think so.  Incest is like, dads molesting their daughters, or boys doing their sisters.  There are good reasons why that sort of thing is illegal.  But I can't imagine that anyone being harmed if we somehow get your mom to do it with you."

"I... guess not."

"Well, it's just a fantasy," I said, chuckling.  "Maybe we'll get close to it.  I mean, she was OK with having sex with me, right in front of you."

"Yeah," she giggled, "that was crazy!  Well, I'll try to help make it happen.  I mean, Mom and me doing stuff."

"That's all I can ask," I agreed.  We cuddled for a while longer, before we got dressed and departed. 

I took her back to their cheap apartment.  Inside the door, Kaitlyn kissed me passionately before dashing off to her room with her shopping bags full of the stuff I bought her.

"She paid the rent?" asked Kathy, frowning.

"She did."  I went to Kathy's fridge, took out a beer, and gave her a summary of the day's activities.

"Good.  You know, Mike, I'm not sure it's a good idea, being so nice to her.  She might get attached.  And you're not going to be her actual boyfriend."

"That's true," I said.  "I'll be sure to make that clear.  I'm her landlord, and her pretend Dad.  And her sexual master.  But no more than that."

"Master, huh?" said Kathy, smiling wryly.

----------------------------------

On Thursday that week, I had a date night with Kathy.  Over dinner, she pointed out that I had taken Kaitlyn to my townhouse, but had never taken Kathy there.

"Oh, you are welcome to come to my place," I said, as we left the restaurant.  I smiled and added in a mock-sinister voice, "But, if you want to come, you must accept my every sexual desire."

"You already have me wrapped around your finger, as my landlord," she said.  "I already have to accept your desires, including letting you use my daughter's mouth.  And whatever it is, if it's sex, I can handle it.  Take me there."

I drove us home.  Inside the door, Kathy wanted a shower together in the big deluxe master bath, that Kaitlyn had told her about.  We stripped and got in.  For a nice while, Kathy enjoyed standing under the water, while I enjoyed running soap-slippery hands over her plump body.  Finally I focused my hands between her legs, finding her rosebud.

"That's my ass," she said, as I pressed a slippery finger in.

"Yes. I plan to take it tonight.  You must accept my every desire."

"Yeah, I know.  It's just been a lot of years since I did it last."

"Don't worry, we'll prepare you."  I fiddled my fingers.  "I don't think anal will be too difficult for you.  That's two of my fingers you've got in your ass right now."  I kissed her, under the water, as I slowly worked my fingers in and out.

Once out of the shower and dry, in my huge soft bed, I lay her out and handed her a bottle of lube and an anal plug.  We spent a little time working the lubed toy into her ass, then I gave her a while to get used to it, enjoying myself in her mouth in the meantime.  Finally, I moved down and sank into her pussy in missionary, the plug making her pussy tighter around me.  We both moaned in pure pleasure.

"Kaitlyn says... you ate her pussy," gasped Kathy, as I slowly fucked her.  "You've... never done that for me."

"You've never needed it.  You've always been hot and ready to go."

"I'd still like it sometimes.  You do it for your real girlfriend, that stuck-up lady."

"Only because I have to.  I'll tell you what.  I agree you should get your pussy eaten.  And I'll let you in on a secret."  I looked into Kathy's eyes, and saw she was just about on the edge of orgasm.  A good time to tell her.  "I'd like to see your daughter do it.  She's already told me she'd do it.  She would eat your pussy."

Kathy's eyes were wild with lust, shock, confusion.  I could tell that this information freaked her out, but her orgasm was already in motion.  Her pussy quivered around me.  I showed no mercy, continuing my firm thrusts.  I could tell the anal plug was stretching everything out, making her clit more sensitive.  Finally, her orgasm receded to the point that she could speak.

"That's.. that's.. the most fucked-up thing I've ever heard you say," she gasped.

"I'm completely serious."

"What the fuck, Mike!  I am not letting my own fucking daughter perform oral sex on me, for your nasty fantasies."

"OK," I said, slowly pulling my cock out of her, and fishing for the anal plug.  "Still, it was incredibly exciting for me, when my tongue was in your mouth, and my cock was in her mouth, and I had a hand on a tit from each of you."

"That's just having sex with us separately, side by side.  That's, whatever.  I don't care.  But what you're suggesting is crazy.  I'm her mother!"

"OK.  So, she doesn't go down on you."  I lubed up my cock, and put it up to her sphincter.  "How about, you let her kiss you?  You know, for the rent."

"Maybe.  Would that be enough?"

"It would be a good start.  Remember, on Saturday, you need me to come in her mouth.  Let's say, you're on your back, and I'm fucking you, and Kaitlyn is standing by, to receive my cum.  But I just can't achieve orgasm.  You need to get me over.  So, you let her kiss you.  Your mother-daughter kiss pushes my buttons, I start to come, I pull out, she sucks my come down."

Kathy stared at me.  "You've really thought about this, haven't you?  Your imagination!  Well, OK.  In that situation, if that's what it takes to pay the rent, sure.  We kiss.  Whatever."

"Good."  I pressed myself gently, slowly, into her ass.  "She's already tasted your pussy juice.  Two weekends ago.  After you left the room, after I fucked you, she sucked me clean.  She didn't mind."

"Wow.  You put it in her mouth then?  You are really something."

"It was a test, and she passed it."  I slowly, slowly sank deeper into her ass.  "So, you're OK with kissing.  How about letting her play with your nipples?  Letting her suck your tits?"

 She groaned.  "You feel huge in my ass right now, and my pussy is still buzzing.  I can't think straight."

"Good.  I'll take that as a yes, because tit-sucking might just be necessary to get me off, to pay the rent.  I'm just checking to see if you are ready to do what it takes."

"There are lines I won't cross, Mike."  She moaned and gasped.  "Slow down, damn it.  I've told you it's been years since I had anal sex."

"I'm not even moving.  I'll just stay here and let you get used to it."  I kissed her, and she kissed back.  "I'm glad to see that your ass is a line I can cross."

"Cross with caution."

"Good enough for me.  I look forward to doing this in front of Kaitlyn.  I want her to watch her mommy take it up the ass."

"You nasty fucker."  She moaned as I slowly pulled out, re-lubed, and went back in.  "I suppose you want her to suck my tits while you're up my ass."

"That's the spirit!"  I moved gently inside her, and found it was slippery enough that I could start the slowly thrust into her ass.  "Now you're starting the understand the shape of the place that I want to take you to."

"A place where my daughter and I are completely yours to do whatever you want?  Cum drinking.  Anal sex.  Lesbian incest, for fuck's sake."

"Yes.  And I accept that you won't go everywhere."

"You're damn right I won't!  I won't lay a hand on my daughter, sexually.  That's just wrong."

"Fine.  We've established that you won't go there, but at least, now you know what to talk dirty about."  I sped up my thrusts a little.  "How does my cock feel inside your ass?"

"Huge and intense.  I want you to come already."

"I'm pretty close.  Your ass feels great.  Talk dirty and you'll push me over the edge."

"Oh, fuck.  OK.  I get it.  I'll pretend.  I'll say the things you want me to say."  She looked into my eyes.  "Do you want me and my daughter to get naked and make out?  Mouth to mouth, tit to tit, belly to belly, pussy to pussy?  Do you want her to play with my clit and suck on my tits and make me scream out in orgasm?"

"Yes!" I growled.

"Do you want to push her head down, between my legs, and force her to eat her own mother's pussy?  Do you want to watch me come, again and again, on her sweet little sucking mouth?"

"Yes, yes, yes!"  I was breathing hard, fucking her ass steadily.

"Then you'll fuck me in my mouth, pussy, and ass, leaving your spunk dripping out of every hole on my body?  And she'll kiss me to drink your sperm from my mouth, and lap it up as it drips out of my pussy and ass?  And she'll shove her hand into my pussy to get all the cum, you'll choke me with your cock in my throat, and I'll come again, on my own daughter's fist?"

I cried out and came hard, deep in Kathy's ass.  For a long time, I just stayed there, breathing hard as my orgasm ran its course.

"You... your dirty talk..." I managed to say, "you're... so good at that."

"I know."

I carefully pulled my shrinking cock out of her, and we spooned for a while, just relaxing together.

"So the little story you just told me... is that how... you're going to pay the rent next Saturday?" I asked.

"Not a fucking chance, Mike."  She chuckled.  "I told you.  There are lines I won't cross."

-------------------------------------

When Saturday came, it turned out that those lines weren't as black and white as she thought.  There were grey zones, and we ventured into several of them.

When I arrived, they were done with breakfast.  Kathy was in the shower, and Kaitlyn let me in.  She took off her top and bra, and we sat on the sofa, talking and kissing.  She already heard about me having anal sex with her mom, and her mom refusing to consider "crossing lines" on doing any mother-daughter stuff.  Eventually Kathy came out of the shower, wearing just a towel.

"Can my daughter take care of the rent this week?" she asked.

"I don't think so, Mom," said Kaitlyn smiling.  "I'm just not that good at sucking cock yet.  You should play with us, to make sure we get him to come in my mouth."

"I think we can go straight to your bed, Kathy," I suggested.  "It will be more comfortable than doing it here on the sofa or on the living room floor.  You and your daughter, together."

"But separately!" said Kathy.  "You can sex us up, side by side.  Nothing sexual between her and me."

"I accept," I said.

We all went into Kathy's room.  The cheap apartment was technically a two bedroom, but the rooms were small, big enough for a queen-sized bed and a dresser, but not much else.  The room was crowded with her stuff.  Kathy pushed some clothes off the bed.  I took her in my arms, kissing her as I removed her towel, and lay her out naked on the bed.  Then Kaitlyn was kissing me, as we worked together to remove her pajama bottoms and panties.  She sat down naked on the edge of the bed, helping me remove my clothes.  My cock sprang out, already half-hard.  She smiled at my cock and went to suck it, but I gently pushed her away, laying her down on the bed next to her mother.

"Give me a minute to appreciate you together," I said, kneeling beside them.  I bend over to kiss Kathy, then Kaitlyn, then sucked on Kathy's nipples, then Kaitlyn's.  I ran my hands over their bodies, comparing the feel of their skin, the weight of their chubby folds.  "This is already quite a fantasy fulfilled.  A mother and daughter together, in my hands."

"We are yours to enjoy," said Kathy.  "Up to a point.  You know where the lines are."

"Yes.  Now, both of you, spread your legs."  They spread.  I ran my fingers over Kathy's pussy, then Kaitlyn's, admiring the similarities, the differences.  Soft light-brown hair, neatly trimmed on both of them.  Kathy's labia were much larger and more pronounced.  I licked my fingers to wet them, and gently explored Kathy's experienced hole with my left hand, and Kaitlyn's virginal hole with my right.  I found their clits, and gently stroked.

"This is nice, so far," said Kathy sighing.

"You're already getting wet," I said, two fingers slipping around Kathy's clit and into her pussy.

"It's my superpower," she said chuckling.

"And you taste nice, as usual," I said, bringing those fingers to my mouth to lick them.

"I'm glad you think so.  Maybe you'll eat my pussy?"

"I might.  Or I might have other ideas."  I showed my fingers to Kaitlyn.  "Kaitlyn, would you like a taste?"

"Yes, please!" she said brightly, "I am so eager to taste my mom's pussy!"  I put my fingers in front of her, and she put them in her mouth to suck them.

"Oh, fuck," said Kathy, in a worried tone of voice.  "That ain't right."

"As you know, your daughter is ready and willing to cross all sorts of lines," I said, moving my fingers back to Kathy's pussy, swirling them around, and returning them to Kaitlyn's mouth.  "It's only you that won't cross them.  And that's fine, for today.  Since you're not ready, I'm just going to eat your daughter's pussy."  I moved down between Kaitlyn's legs.  "You can masturbate while you watch me make her come."

"Oh, fuck," said Kathy, but she moved aside and up a bit, so that she could reach between her own legs, and watch what I was doing.

"Oh, thank you Daddy!" said Kaitlyn, as my mouth descended on her young vulva.

She was quick.  Barely three minutes of clit-licking, and Kaitlyn was gasping in orgasm, as her mother watched.  Her taste was in my mouth, and my face was wet, partly from my own saliva and partly from her pussy juice, dripping down my chin.

"That was hot," said Kathy, clearly well on her way to an orgasm of her own, her fingers moving rapidly between her legs.

"Yes," I said, lifting myself up and crawling to Kathy.  Before she was aware of what was happening, I was kissing her.  My tongue in her mouth.  She stiffened up when she realized that she was tasting her own daughter's pussy, but then she relaxed and her tongue sought mine, kissing me back.

"You nasty fucker," she said, when we finally broke the kiss.  Her hands were still moving on her clit.

"No line crossed," I said.  "You haven't laid a finger on her.  Just like you said."

"You're bending the lines," she complained, but arousal was clearly winning.  "Just fuck me, already."

"Not until I get the blowjob I've been looking forward to.  Both of you working together.  You've sucked it and handed it to her before.  This is no different."

"Fine!"  We shuffled around on the bed.  I sat up leaning on a pillow, as both of them knelt between my legs.  Kaitlyn went for my cock first.  She sucked for a minute, then passed it over.  Kathy looked apprehensively at my erection, dripping with her daughter's saliva, but then she took it in her mouth and got busy sucking.  Kaitlyn alternated between watching her mom's technique, and smiling up at me.  I took in the sight of the mother-daughter blowjob, and also appreciated their plump naked bodies on their hands and knees, heavy with weight, their tits hanging down and swinging a little back and forth as they sucked.  I enjoyed going back forth, mother, daughter, mother, daughter.

"Help her," I told Kathy, as Kaitlyn was doing her best, with about half my cock in her mouth.  "Play with my balls.  Jack the shaft.  Tell me what you want."

"I want you to come in her mouth," said Kathy, her hands getting busy.  "That's why I'm jacking you off into her sweet little sucking mouth.  I want you to ejaculate and give my daughter a giant load of sperm to drink."

"I want you to have some, too," I said.  "How about after I come, you kiss her and taste my cum in her mouth?"

"Nope.  Not happening."

"OK then, after I start coming, pull my cock out of her mouth and take the rest of it?  I want to see you both open your mouths, and show me the cum on both your tongues.  Can you do that?"

"Mmm-hmmm," agreed Kaitlyn, with her mouth full.

"Sure.  OK," agreed Kathy.

"Great."  I felt myself getting close.  "Damn, Kaitlyn, your skills are improving!"

"Do it!" urged Kathy, jacking my shaft faster.  "Sperm her little mouth!  Give it to both of us!"

I started coming.  I felt one, two pulses going into Kaitlyn.  Then quickly I was slipped into Kathy, who held the head of my cock just inside her mouth as I finished spurting.

"See?" mumbled Kaitlyn, opening her mouth and sticking out her tongue, which was indeed covered in cum.

"Mmm-hmmm," agreed Kathy, pulling back and showing me the cum on her tongue.

"Beautiful, both of you.  Now swallow."  They did.

"Still doesn't taste good," said Kaitlyn.  "But that was fun!"

"Well, now you've come, and she's come, and you're not hard anymore," said Kathy frowning.  "I don't get an orgasm?"

"If you're ready to cross a line, I'm sure your daughter would lick your pussy," I said smiling.

"I would," said Kaitlyn quickly and quietly.

"Oh honey, that's sweet, but that's just wrong," said Kathy.

"Lay out on the bed," I said.  We moved so that Kathy was laying on the middle of the bed.  I spread her legs and got between them.

"You're going to lick me?" asked Kathy hopefully.

"Nope.  I'm going to rub my soft cock again your clit, like this."  I used the rubber end of my cock to flick her clit.

"That's just teasing me."

"Exactly.  Now, you could do something to get me hard.  Let her kiss you."

Kaitlyn was already kneeling beside us.  She leaned in and smiled as she looked into her mom's eyes.

"Oh, fuck," said Kathy, looking at her daughter's lips.  "This is wrong."

"It's just a kiss," I said.  "It's not sex."

"I want to do it, Mom," said Kaitlyn sweetly.  "I like doing things to turn Mike on.  And I like kissing, a lot.  I like kissing boys, and I like kissing Mike.  I've never kissed a girl.  I want to try it with you."

"Oh, damn it," gasped Kathy.  "Fine."

Kaitlyn moved in.  Their lips met.  I could feel their lips negotiating.  Kathy was trying to keep the kiss shallow, Kaitlyn was trying to make it deep.  Kaitlyn won.  My cock gave a lurch.

"It's working," I said, rubbing my growing cock on Kathy's wet inner labia, then pushing in.  "Keep kissing, and I'll be hard enough to fuck you nicely."  I reached up, and used both my hands to gently pull and twist Kathy's nipples.  I knew the effect it would have.  Kathy moaned involuntarily, muffled by the kiss.  I grew harder, and started to thrust gently.

"It's so nice!" said Kaitlyn, breaking the kiss, turning her face to watch me thrust.  "Is it sexy, Mike?"

"You French-kissing your mom?  You're damn right it's sexy.  Did you get her to suck your tongue?"

"Not yet," she said, then went back into the kiss.

I shifted my body so that I could really lean in and give Kathy the kind of steady, hard fuck that she liked.  She moaned again.  I took one of Kaitlyn's hands, and placed it on Kathy's left breast.  Without breaking the kiss, Kaitlyn got the idea, rolling her mom's nipple between her fingers, tugging on it.  Kathy moaned again.

"That's your daughter playing with your tit," I said, fucking harder.

Kathy tried to gently push Kaitlyn away, but I leaned in, putting my body in the way, and taking an opportunity to suck Kathy's right nipple.

"This is fun!" said Kaitlyn, breaking the kiss to pay attention to twisting and pulling the nipple in her grasp.

"Suck it," I said.  Kaitlyn moved down to suck the nipple.

"This is wrong," said Kathy, quietly.  "Oh, fuck, your cock feels so good.  Don't you dare stop."

"You're not being a bad parent, Kathy," I said, between thrusts.  "You're not laying a finger on her.  You're just being a little naughty.  A naughty mommy, letting your teenage daughter suck on your tits."

"You're... so... hard!" gasped Kathy as I pounded her.

"That's what you get, for being a naughty mommy.  You get my rock-hard cock."

'I... shouldn't be... this isn't..." gasped Kathy.  "Damn you!  It's too good... but it's wrong..."

"Kaitlyn," I instructed.  "Your mother's babbling.  Stick your tit in her mouth."

Kaitlyn let go of the nipple she was sucking, then grasped her left tit and pushed it at Kathy's face.  Kathy put up only token resistance before accepting it.

"Yeah, Mom!" giggled Kaitlyn.  "Suck it!"

"You're such a good girl, Kaitlyn!" I encouraged.  "Do you like your mom sucking on your tit?"

"Yeah!  It's sexy.  I mean, it feels nice. But it's really sexy that we're making her do it."

"That's so true," I agreed.  "Your mom just needs a little encouragement to try new things, and the perfect time is when she's getting fucked hard."  I felt Kathy's pussy grip me in a familiar way.  "Why don't you tell her what you really want?"

"Yeah!" said Kaitlyn, "Mom, I love that you're sucking on my tit, but what I really, really want is for you to eat my pussy!"

Kathy came, hard, squeezing my cock.

"She's coming," I told Kaitlyn.  "She won't admit it, but I think the idea of eating your pussy turns her on."

"Oh, wow!"  Kaitlyn watched for a minute, then pulled her tit back and resumed kissing her mother.  I kept giving it hard and fast to Kathy, who came another couple times, putting up no resistance as Kaitlyn kissed her and played with her tits.  Finally, I felt my own second orgasm approaching.

"Kaitlyn," I said, "you had to share my first load of cum with her.  Since you got short-changed, I'm happy to give my entire second load to you."

"Cool!" giggled Kaitlyn, looking down at the point where my hard cock was slamming into her mother.  "So, um, you want to pull out?"

"Yes.  Get your mouth down here, get ready."

Kaitlyn moved down, her head hovering over Kathy's plump belly.

"Wow!" she said, getting a close-up view of the point of penetration.

I grabbed one of Kathy's tits, and pushed it up to her face.  Nearly drunk on sex, she took her own nipple into her mouth and sucked it, hard.  She started coming, again, and it set me off.  Just as her orgasm began to recede, my own was beyond control.  I whipped out my cock and slipped into Kaitlyn's eager, waiting mouth.  She swallowed another squirt or two of my cum, flavored by her mother's orgasmic juices.

I fell onto the bed, and both of them cuddled up to me, on my right and left.  No words were spoken.

After a long, sweet cuddle, Kathy moved up to kiss me.

"Mike," she said, "we're going to have to re-evaluate our relationship."

----------------------------------------

That re-evaluation was worked out in a series of long conversations, that day, and during our date on the following Wednesday.  In short, Kathy felt that what she was doing, letting me have sex with her and her daughter together, was worth more than the rent.  She wanted a small weekly payment, so she could quit her part-time waitress job.  She wanted a gym membership.  She wanted to go back to school part-time, to finish the degree that she had to quit in her 20s.  And she wanted her pussy eaten, by me, regularly.

In exchange for this, she would let me keep bringing Kaitlyn into our sex life - and she would let me gradually, over time, bend the lines on what she would do, sexually.

As for Kaitlyn, she was all in.  She practically begged me to accept her mom's proposal.  She made it clear that she would do anything, absolutely anything sexual I wanted, ever.

I could afford it.  I said yes.

----------------------------------

My time with Kathy and Kaitlyn was scheduled, twice a week, once on the weekend and one weeknight.  Every week, we nudged Kathy a little further.

On the first date post-agreement, I did not need to get Kathy in the throes of sexual passion before she would kiss Kaitlyn.  The kissing and nipple play began right at the start, during the foreplay and warm-up.  I licked both of them to a quick orgasm, then received a mother-daughter blowjob, which was now accepted as normal.  During the long fuck that followed, I put Kaitlyn's hand down between our legs.  She touched her mom's clit for the first time, learning how to rub it, driving Kathy's sexual peaks even stronger during the fuck.  It was no longer part of our agreement that most of my cum needed to end up in Kaitlyn's mouth, but that happened anyway.

On the second date, I brought them both to my townhouse.  We made out, as a threesome, in the big walk-in shower.  Kissing and caressing went everywhere, and for the first time, Kaitlyn was able to slip some fingers into her mom's pussy.  We attempted some shower sex, with Kaitlyn kneeling and sucking me as I held and kissed Kathy, then I bent Kathy against the wall and fucked her from behind as she kissed Kaitlyn.  It was hot, but standing in the water was a little awkward, so we toweled off and the sex continued on my big bed.

On the third date, I arrived with sex toys.  A lubed plug went into Kathy's ass, and to my surprise, Kaitlyn wanted one too.  After some foreplay and vibrator orgasms for both of them, they gave me a mother-daughter blowjob that resulted, for the first time, in sharing my cum between their mouths in a kiss.  Then I replaced the plug in Kathy's ass with my cock, giving Kaitlyn an educational demonstration, watching her mother enjoy anal sex.  Kathy talked dirty the whole time, and then Kaitlyn did too, about how she wanted to try anal sex too.  We both told her no, firmly.

On the fourth date, a major line was crossed.  Kaitlyn and I started by both making out with Kathy, both of us slipping our fingers around in Kathy's wet pussy.  I then handed Kaitlyn a large dildo to put in her mother's pussy, while I went up and fucked Kathy's mouth.  Finally, Kaitlyn got impatient, pulled out the dildo, and just dove her face right in, straight-up eating her mom's pussy.  Kathy was a little freaked out - she might not have expected it to happen so soon - but she didn't resist.  In fact, she came hard, repeatedly.  Kaitlyn was delighted, that she was finally able to fulfill what she said she would do for me, and also thrilled to be able to make her mom come.

On the fifth date, Kathy finally worked up the courage to touch her daughter's pussy.  I was fucking Kathy, with Kaitlyn leaning over her.  I whispered a suggestion in Kathy's ear.  Kathy's hand hesitantly came up and started to explore Kaitlyn's vulva, and then rub her clit.  Kaitlyn squealed in happiness at her mom's touch.  I told Kathy she was being such a good naughty mommy, which made her blush and come on my cock, repeatedly.  When Kathy couldn't take it anymore, I pulled out to come in Kaitlyn's mouth, then Kathy, in her happy well-fucked state, rolled over and masturbated Kaitlyn to an orgasm.  It was a truly beautiful sight, mother and daughter, side by side on the bed, entwined, kissing, hands on each other's pussies.

------------------------

The sixth date was a Saturday, at their small apartment.  As usual, I was freshly showered, neatly groomed, well-dressed, and horny.  As usual, they were just finishing breakfast in their casual night-time attire - a satin robe for Kathy, and pajamas for Kaitlyn.

There were a few small waffles left on the table, so I pulled up a chair, grabbed a plate, and poured syrup on one.

"Good morning, sex master," giggled Kathy.

"Oh, come on, Mom," said Kaitlyn.  "He's not our master.  He's just a guy who's nice to us and we do sex stuff with.  And he's my pretend Daddy."

"That's right," I said.  "It's a simple relationship, really."

Kathy frowned.  "The... sex stuff has been getting pretty crazy."

"You knew we would be crossing some lines," I said.  "Are we moving too fast?"

"Maybe.  I don't know."  Kathy sighed and pushed her plate away.  "You know it freaks me out, the idea of actually doing it, what I know you want."

"You mean, you and your daughter having sex with each other?"

"Yes.  To begin with, I don't think I'm actually bisexual.  I don't get excited by the thought of having sex with women."

"But she is not just any woman.  She's a very cute, very enthusiastic, adorable young woman.  Who just happens to be your daughter.  And you're doing very well, so far.  You say you're not bisexual..."

"But I totally am!" interjected Kaitlyn.  "And when I licked you last week, you totally came, like, a lot."

"Right," said Kathy, "and that's the other point.  Incest, Mike.  I know you don't think it's really incest, because we're both women.  But it really is.  If you had your own children, maybe you'd understand.  Of course I love my daughter, I want the best for her.  To do these ... perverted .. acts with her, it fills me with doubt, I wonder if I'm being a good parent.  But you don't have a daughter, so you can't relate."

"My real dad is a jerk," interjected Kaitlyn.  "Mike is nicer.  If Mike was my real dad, if I was his daughter, I'd have sex with him."

"Kaitlyn!" exclaimed Kathy.  Kaitlyn giggled.

"And that's a good point," I said, finishing the waffle on my plate.  "It would be one thing if Kaitlyn wasn't into it.  If you were using your authority as a parent to make her do things.  But it's quite the opposite.  She wants it.  She made her own decision."

"As much as a 14-year-old can make an informed decision," argued Kathy.  "In my mind, she's still my little girl, and I need to protect her."

"I'm 15 next month, and you know I'm not a little girl," protested Kaitlyn.

Kathy sighed.  "Yes.  Yes, I know it.  But my heart still worries."  She looked at me.  "I've done so many things with her, already.  So much sex stuff.  I guess there is one act I haven't done."

"You haven't performed oral sex on her," I said.  "I agree that's the big one, but that's hardly the only one.  I do have plenty of other things in store for you.  But yes, you'll need to get over that hurdle.  Sooner or later, you'll use your mouth on her pussy."

"It's not a big deal, Mom!" protested Kaitlyn.  "I did it for you.  You loved it."

"I'm not going to push you," I said.  "Do it when you feel ready."  I stood up and moved to where Kaitlyn was sitting at the table.  I pulled off her pajama top, and cupped her tits.  "In the meantime, just go with the flow.  Your job is to push my buttons, to turn me on, to talk dirty, to do the things that you know I'll find sexy.  Eventually, you'll cross every line.  If it helps you, just think of it the way you used to, as paying your rent."  I dipped two fingers into the maple syrup on Kaitlyn's plate, then rubbed them over her nipples, making her giggle.  "C'mon, take our your boobs, play along."

Kathy sighed, watching me for a minute, then she smiled and pulled her tits out of her robe, and dabbed syrup on her nipples.  "I suppose I'm doing this for some sexual reason?"

"Of course.  You want to suck your daughter's nipples."

"I do?"

"Yes.  Beg for it."

Kathy smiled.  "OK.  I get it."  She stood up and approached us.  "Mike, I can't help but notice that you've pulled my daughter's hot tits out at the breakfast table.  They look delicious.  May I please suck on her cute, sweet little nipples?"  She reached her hands down, and together we fondled Kaitlyn's breasts.

"You may," I said.

"Doesn't she have to ask me, too?" asked Kaitlyn, giggling.

"You're right," agreed Kathy.  "Katie, sweetheart, can Mommy suck on your nipples please?"

"Yeah, you can, naughty mommy!" giggled Kaitlyn.

I held Kaitlyn's heavy breasts, to point her nipples up, as Kathy bent in and sucked each of them.  I didn't have to suggest the deep mother-daughter tongue kissing that followed, or when Kaitlyn began sucking on Kathy's syrup nipples, while Kathy and I kissed.  I could feel the sexual energy building between the three of us, right there at the dining room table.

"Let's take this to the bedroom," I suggested.

On the bed, our foreplay went as it usually did: lots of kissing, undressing each other, nipple play, occasional teasing sucks of my cock.  Kathy ended up on her back, with Kaitlyn and I working together on her.  Our fingers played together in Kathy's pussy.  I slid down and took Kathy's clit in my mouth - this was, after all, part of the agreement that I made, that Kathy would get oral sex from me.  As I sucked, I put a few fingers into her, finding her wet and responsive.

"Your turn, Kaitlyn," I said after a minute.

"Oh, God," said Kathy, sighing.  "Sweetheart, you don't have to..."

"Don't forget, Kathy," I admonished.  "Last week, you just let her do it.  Passively.  Remember, you're doing this for me.  This week, you have to admit you want it.  Actively.  Ask her for it."

"Right.  OK."  Kathy looked into Kaitlyn's eyes.  "Sweetheart, you know Mike wants to see us commit nasty, perverted incest with each other?"

"Yeah!" giggled Kaitlyn enthusiastically.  "He does.  So let's do it!  What do you want?"

"I want..."  Kathy struggled to say it.  "I want... you to put your face down there, between my legs.  I want you to put your mouth right on my pussy, and I want you to lick my clit, and I want you to give me an orgasm."

"Oh, wow, Mom," said Kaitlyn smiling, playing it up, reaching down to stroke Kathy's clit.  "Isn't this the same pussy hole I was born from, almost 15 years ago?"

"Yes, and I want you to shove four fingers into my pussy hole while you're licking it."

Kaitlyn giggled, moving down and getting busy.  I moved up the bed, putting a pillow behind Kathy's head so she could look down.  A plus-size woman like Kathy, laying flat on her back, can't see what's going on between her legs, without a bit of elevation to see over the belly bulge.  Together, we watched Kaitlyn, her sweet face framed by her mother's heavy thighs.

"Is your daughter licking you well?" I asked Kathy.

"Oh, Mike," she sighed, her face a mix of complex emotions.  "She is.  Her tongue is wonderful.  And, it's so wrong."

"And her fingers.  Is your daughter finger-fucking you well?"

"She is!  Oh!"  Kathy's eyes fluttered.

My cock was painfully hard and hadn't had much attention yet.  I moved up and pushed it into Kathy's mouth.  She turned her head to accept a shallow mouth-fuck.  I used her mouth as a wet hole, but I wasn't looking at it.  I was watching Kaitlyn's incestuous pussy-eating.  Truly, a thing of beauty.  Kaitlyn's cute face, the excitement in her eyes, her mother's thick smooth thighs around her head.  Kathy's body occasionally quivered, as her arousal built.  After a few minutes, Kathy came,  hard, pushing Kaitlyn's head away.

"Yeah!  I did it!" gasped Kaitlyn excitedly.  "What next?"

"You did great," I agreed.  "I'm going to fuck your mom now, and I'm going to come inside her. Do you remember, in the porn we watched together, what they call a creampie?  You're going to eat it."

"Oh, wow.  Really?"

"Yes.  I'm going to leave your mom's pussy full of cum, and you're going to mash your face in there and suck up all the cum and drink it.  It just combines two things you're already OK with, eating pussy, and eating my cum.  Are you ready?"

"Yes," she agreed.   "Anything for you, Daddy."

"Oh, nasty!" gasped Kathy, but she didn't complain any further as I mounted her and gave her a nice long, strong fuck.  She came a couple times before I did.  By the time I pulled out, leaving a trail of cum, her pussy was a mess.  Kaitlyn didn't hesitate.  She got down there, licked up the loose cum on her mother's labia, then went in for the rest, slurping away happily.  Kathy moaned as her daughter's tongue moved around on all her sex-sensitized areas.  Finally, Kaitlyn lifted her wet mouth and smiled at us.

"It's mostly Mom's pussy juice," she said, "but I do taste a little bit of Daddy cum in there too."  She giggled.  "Pussy tastes better."

"There's a little bit more on here," I said pointing to my cock.  "You can suck me clean."  Kaitlyn eagerly complied.

"Now you and Mom had your orgasms," she said, licking her lips.  "Is it my turn?"

"You bet.  Get up there on the bed and spread your legs.  Kathy, come down here with me.  You're going to watch up-close as I eat your daughter's pussy."

We rearranged ourselves on the bed.  I lay between Kaitlyn's legs, propped up a little on my elbows.  Kathy nestled in beside me.

"Isn't it beautiful?" I said, gently spreading Kaitlyn's outer labia, dipping a finger in for wetness, then running it around, especially over her clit, making it pop out a little more.  Kaitlyn's hymen was small and crescent-shaped, there in the lower half of her vaginal opening.  Just a note, if you read a lot of erotica, you hear so many confused accounts of the hymen.  People seem to think that it's some mysterious fleshy barrier somewhere part-way down inside the vagina, hidden somehow.  Those people have never seen a virgin pussy up-close with the lights on.  Just gently spread the labia and the hymen is right there, in plain sight!

"She is beautiful," agreed Kathy.

"Watch."  I moved my face in a bit, and used my tongue to tease all around before settling in on Kaitlyn's clit.  I continued my rhythmic licking for a minute, feeling Kaitlyn start to get into it, her arousal building, her legs quivering.  Then I pulled back, and spoke gently to Kathy, "Touch her."

Kathy gently ran her finger around her daughter's vulva, inner labia, and clit.

"You made her come with your fingers last week," I said.  "Are you ready to take the next step, with your mouth?"

"I don't know," said Kathy softly.  "It feels like a huge step."

"You've come all the way, right up the line.  It's up to you to cross it."

"I know.  I'm not so scared of doing it, right now.  I just don't know how I'll feel about it later.  For the rest of my life!  I'm going to be that woman who did it with her own daughter.  And maybe once I've done it, you'll lose interest in us, and you'll move on, and I'll just be broke again.  Will I still respect myself for what I did?"

"Kathy," I said soothingly, "You're just breaking a taboo.  I think you're an amazing, sexually adventurous woman.  I respect you for coming this far.  And I'm not going to lose interest.  A mother and daughter, that are willing to break such a taboo, are a rare and precious thing!  It's your choice.  All I can try to tempt you, with money and gifts and security.  But ultimately, it's your decision."

"Please, Mom!" said Kaitlyn.

For a minute, Kathy stayed quiet, thinking.  Her finger moved slowly around Kaitlyn's vulva, studying it.  Then, she turned her face to me and kissed me, hard.

"I'll do it!" she said firmly.  Her eyes had a fierce look of excitement, fear, and resolve.  She turned her face, and planted her mouth on her daughter's pussy.

"Oh!  Yes!" gasped Kaitlyn.

"Good girl!"  I encouraged.  I moved back a bit, to admire the full sight: Kaitlyn's plump naked body spread out on the bed, her mother between her legs.  I moved up and kissed Kaitlyn, and toyed with her nipples.  Together we looked down at Kathy.  "Look!  She's really doing it."

"I know!  Thank you, Daddy!"

"She's never eaten pussy before, so you can give her advice.  You'll be teaching her to lick you the way you want to be licked."

"Yes, you can, sweetie," said Kathy lifting her mouth for a moment.

"Oh, yeah."  Kaitlyn giggled.  "Move your tongue down a little, Mom.  It feels better on my clit that way.  And not so hard.  Kinda, faster and softer?"  She giggled, and then she gasped.  "Yeah!  Like that.  Oh, wow."  Then she stopped speaking, breathing hard.

My cock was hard again, just from watching this spectacle, but I didn't want to interrupt in any way.  I let them go at it, for several long minutes, until Kaitlyn came, and Kathy lifted her mouth, smiling at her accomplishment.

"You did it," I said.  "Congratulations!  Now go up and kiss your daughter.  Kiss her like a lover, because that's what you are now.  Your daughter's lover."

"Yes.  I am."  Kathy moved up, her naked body laying atop Kaitlyn's as they kissed passionately.

"Now, if you don't mind, your incestuous act has made my cock as hard as a fucking rock."  I reached for the bottle of lube on the bedside table.  I lubed one finger and explored between Kathy's buttocks, finding her rosebud.

"Yes, you can use my ass." gasped Kathy, between kisses.  "You can do anything!  I have no resistance left.  I'll do anything.  My body is yours, my daughter's body is yours.  Use us for your pleasure, use us in any way you like."

"Thank you," I replied.  "I will."  I spent a minute stretching her ass with lubed fingers, waiting for  her to relax around them, and then I got up on the bed, straddled her, and began the slow process of getting my lubed cock into her ass.  She still wasn't used to anal, and it's never a quick thing.  Eventually I was ass-fucking her properly, burying my cock to the hilt on each thrust.  Kathy was gasping, and gently kissing Kaitlyn.

"I love you, Mom," I heard Kaitlyn say, between kisses.

"I love you too, sweetie.  I can't believe we're doing this, but here we are."

"I'm so happy you did it.  And I'm grateful!  You made me come so hard, Mom.  And now we can fulfill all of Daddy's kinky desires.  And we're going to have lots of great sex with him, and with each other."  She paused.  "What does he feel like inside your butthole?"

"He feels huge.  And it hurts a little, but not as much as last time.  And there is a little bit of pleasure in with the pain."

"I want him to fuck me, Mom.  In my pussy and in my butt."

"You're too young, sweetie.  Even he says so."

"Well, I'll be 15 soon.  Maybe you'll let me do it then."  She paused.  "Can I suck your nipples, Mom?  I know how much you like it.  Lift up a little."

"Yes, sweetie!  Suck my tits as he fucks my ass."

That's how they were, when I finally came deep inside Kathy.

---------------------------------------------

As for my girlfriend Susan, that worked itself out, in a surprisingly happy way.  We loved each other, we enjoyed each other's company, but she just wasn't into having sex with me.  Finally, we had a long conversation about it, and I learned that it wasn't me - Susan just wasn't sexually excited by men.  She fell in love with men, but didn't feel turned on by them.  On the other hand, she didn't connect emotionally with most women, but she lusted after them - especially younger women.  This finally explained why she was never possessive of me, letting me keep my sexual relationship with Kathy.  As far as Susan was concerned, Kathy was doing her a favor, by taking care of my sexual needs that Susan didn't feel like meeting.

I boldly suggested to Susan that we bring a younger woman into our relationship - not for me, not the clich� of the guy who wants a second woman in his bed, but for her.  She cautiously agreed in principle, but she was certain that I would not find such a woman.

So, I brought her Kaitlyn.

Their first meeting started awkwardly, but by the time Kaitlyn was finally between Susan's legs eating her pussy, the awkwardness was gone.  Susan was delighted and excited to have a cute 14-year-old girl to kiss, fondle and exchange oral sex with.  I was usually present, and sometimes Susan would get so excited by Kaitlyn that she would actually ask me for intercourse.  Fucking Susan was finally pleasant for both of us, as long as Kaitlyn was in bed with her.

---------------------------------------------------

My relationship with Kathy and Kaitlyn continued.  Sometimes it was more than twice a week.  We started to do more than have sex, especially Kaitlyn and I.  We worked on her homework together, we played videogames together.  Sometimes I'd drop by their apartment on the way home from work, just to say hi and get a quick blowjob.  Saturday was the day reserved for longer play, and every week I'd find something new for them, sexually.

One week, it was toys again.  They both enjoyed vibrators on their clits, and Kathy enjoyed a nice thick dildo in her pussy, but we had to experiment for a bit to find a thin dildo that worked inside Kaitlyn, stretching her hymen just a little.  We all practiced for a long time, to find the exact angle, depth, and style of penetration that Kaitlyn could enjoy comfortably inside her virgin hole.  To help her enjoy it, we both licked her clit, helping her come with a dildo inside her.  Kaitlyn promised that she was learning to enjoy penetration, and kept several toys to practice with each night.

Another week, it was all about cum play.  I had them watch internet porn, showing how to cumswap, then we tried it.  A mother-daughter blowjob ended with me coming into Kaitlyn's mouth, who held it carefully and passed it all to her mom in an open-mouth kiss, then back again.  They did great!  Then we had normal sex, fucking Kathy doggy-style while she sucked Kaitlyn's pussy, until they both came.  Then I rolled Kathy over, and Kaitlyn held her mom's tits together, for a tit-fuck.  I came all over Kathy's tits and nipples, for Kaitlyn to lick up and share with her mom in a kiss.

Another week, it was all anal.  At my townhouse, we went into my big walk-in shower together, and we played with soapy fingers in both their asses.  After much washing and rinsing, I asked Kaitlyn if she was willing to try licking her mom's asshole.  She smiled and didn't hesitate, getting right down on her knees and pushing her face between Kathy's large buttocks.  We kept going until Kathy came that way, bent forward against the wall of the shower, her legs spread a little, my fingers playing with her clit from the front, Kaitlyn's fingers stuffed into her pussy from behind, and Kaitlyn's tongue up her ass.  I took my turn, fucking Kathy's ass to a quick orgasm.  We got Kaitlyn's ass similarly clean, then got out of the shower and Kaitlyn lay on her belly, with a vibrator on her clit, as Kathy and I played with Kaitlyn's ass using tongues, fingers, toys, and lots of lube.  Kathy was vigorously thrusting a thin dildo into Kaitlyn's ass, when Kaitlyn came.

Another week, the focus was all on their lesbian mother-daughter interaction.  They dressed up in nice clothes, did a slow dance for me with a lot of kissing, then slowly undressed each other as they danced.  I had them both beg for each step, Kathy begging to suck on her daughter's tits, Kaitlyn begging to push down her mom's panties, Kathy begging to finger her daughter's cunt, Kaitlyn begging to suck her mom's pussy.  They took turns sitting on each other's faces, then it ended up on the bed, in their very first mother-daughter 69, with Kaitlyn on top.  I loved the show, and found a way to insert my hard cock into their 69, enjoying myself in Kathy's pussy and Kaitlyn's mouth, until I came inside Kathy, making a creampie for Kaitlyn to eat.

Then, Kaitlyn turned 15.  She was absolutely firm on what she wanted for her birthday: to part with her virginity.  She prepared for the event carefully, for many days, with lots of stretching and penetrating herself with dildos, front and back.  On the day, there was birthday cake, presents, and then adjourning to the bedroom where she wanted both of us to eat her pussy to orgasm.  I then offered my cock, which Kathy dutifully assisted in working into Kaitlyn's pussy.  Her hymen was practically gone already, but nonetheless I fucked her gently and carefully, while she used a vibrator on her clit.  She really wanted to feel me come inside her, which I was happy to do.  She squealed in happiness, but that wasn't enough.  No, she also wanted her first anal sex.  I needed to get hard again, so I instructed Kathy to clean my cum out of her daughter's hole with fingers and tongue, and eat every bit of it.  Kathy did so reluctantly, and her reluctance got me hot and hard again quickly.  Going into Kaitlyn's virgin ass was surprisingly easy, due to all the pre-stretching and pre-lubing.  I think she even enjoyed her first real anal, which is amazing.

Once there was no awkward virginity to work around, our sex sessions opened up even further.  I put them face to face on the bed and fucked them both, moving my cock between them, feeling the difference between mother-pussy and daughter-pussy.  I fucked Kaitlyn while she ate her mom.  As did what I had joked about long ago, telling Kathy to fuck herself with vegetables, then Kaitlyn tried it with skinnier vegetables, then they pushed them into each other.  I put them in a 69, and fucked Kaitlyn's tight little ass while she moaned into her mom's pussy, and came on her mom's mouth.  We had sex in both their beds, we had sex in the bathroom, we had sex in the kitchen table, we had sex in every room of my townhouse.  At my instruction, Kathy learned to take Kaitlyn's fist in her pussy.  They became experts at getting each other off with mouths, tongue, fingers.  They became experts at quickly preparing to take my cock deep in any of their holes.  They became experts at talking dirty the whole time.

--------------------------------

One Saturday, months later, I showed up at their place with a large shopping bag.

"Hi, Mike," said Kathy, as I came in and sat down at their dining table.

"What's in the bag, Daddy?" said Kaitlyn, coming around in her pajamas to give me a deep kiss, before sitting down with us.

"Some things.  Some new kinds of sex for us to try."

"That's impossible," laughed Kathy.  "You've fucked and sucked us every which way, and had us do each other every way too.  There are only so many combinations of our bodies, and your cock.  What on earth is in the bag?"

I chuckled and reached in.  I pulled out a large leather flog, and set it on the table.

"Oh my God," gasped Kathy.

"Cool!" cried Kaitlyn.  "I want to use that on Mom!"

"And this," I said, reaching in and grabbing an elaborate assemblage of straps, padding, and holes.

"What the hell?" asked Kathy, laughing.

"I know what that is!" said Kaitlyn.  "It's a strap-on harness.  And it looks like a fancy one!  I've seen 'em like that in lesbian porn online."

 "I've bought two of them," I said.  "Both of them are made to accommodate wide hips.  You can adjust them to fit each of you."

We went into the bedroom.  I kissed and undressed Kathy, pushing her down on the bed on hands and knees, then Kaitlyn and kissed and undressed each other.  I pushed my growing cock into Kathy's mouth.

"Flog your mom's ass," I instructed.  "Start softly.  Let's see what she can handle."

"Oh, cool," giggled Kaitlyn.

Kathy moaned around my cock, as Kaitlyn gave her a series of whacks.  The soft leather of the flog made a nice, big thwacking sound on Kathy's wide ass.  Kaitlyn had a big grin on her face.

"Let's give her a challenge," I said.  "Maybe some deep-throat practice."

"Yeah!" agreed Kaitlyn.  "Shove your cock down my mom's fucking throat.  Choke her with it while I flog her!"

"Do you understand, Slut Mom?" I asked Kathy, using one of our pet names for her.  "You're going to have to hold your breath and not gag, as your daughter gives you ten whacks.  If you don't make it to ten, I'm going to pull out and we'll start over, with harder whacks."

"Yes!  Use me, train me," said Kathy.

I grabbed the back of Kathy's head and pushed myself deep, until I was buried to the hilt.  Kaitlyn started flogging, counting each swing.  Kathy only made it to four before she slapped her hand down, signaling defeat.  I pulled out and she gasped for air, saliva running down her chin.

"Only four?" said Kaitlyn, giggling.  "Bad Mommy Slut!  Try harder!"

Kathy made it to five the next time, then I could tell she was really trying hard and made it to seven.  Her throat felt nice, but what really made the situation fun for me was watching the obvious delight Kaitlyn took in swinging the flog.

"Let's give her a break and warm her up a bit," I said.  "I'll fuck her mouth shallow enough for her to breath."  I grabbed Kathy by the hair and began to thrust.  "What can you do for her?"

"I can shove some fingers in my mommy's big pussy," said Kaitlyn, doing that.  "Mmm-hmmm, she's already a little wet."

"Good.  What else?"

"I can eat her ass.  Would you like that, Daddy?  Do you want to see me push my tongue up my mommy's butthole?"

"Yes, good idea."

We did that, exercising Kathy's three holes, until Kaitlyn declared that her mom's pussy was dripping wet.  We returned to throat-fucking and flogging her, but after a few attempts, she still hadn't reached 10, and then the game ended because I came down her throat.

I had Kathy stay there, on her hands and knees, reaching under herself to rub her clit, as Kaitlyn and I figured out how to strap on a harness to Kaitlyn's hips, and chose a large dildo to snap into it.  Kaitlyn was delighted, stroking the new cock between her legs.

"Do I get to fuck my mom, now?" she asked cheerfully.

"Soon.  First, make her suck you."

"Oh, wow.  Cool!"  Kaitlyn moved around in front of her.  "Mommy Slut!  Suck my dick!"

I sat back and just watched.  They were so well trained, now, that I didn't have to do much.  They tried out different ways that Kathy could suck her daughter's cock.  Kaitlyn talked about how fun it was, even though she couldn't feel her mom's mouth, it felt powerful and dominating, a lot like the fun she had in sitting on her mom's face.  Kaitlyn tried being passive, letting her mom do the work, and also tried being active, holding her mom's head, even gripping her by the hair and pushing her silicone cock into her mom's throat, as she'd seen me do to Kathy so many times.  I went to Kaitlyn, holding her tits and kissing her deeply as she thrust into her mom's mouth.

"Do you want to fuck her?" I asked softly.

"Yes, Daddy," Kaitlyn replied with a giggle.  "I really want to fuck my mom."

"You've fucked her so many ways, already.  You've fucked her with fingers, your tongue, with toys, even with vegetables.  But now you have a cock hanging between your legs, like a man."

"Yes, Daddy.  I want to fuck my mom like a man.  I want to fuck her the way you fuck her."

"Please," moaned Kathy.  "You've left my pussy dripping wet and I'm just waiting for a cock, any cock."  She looked up at Kaitlyn.  "Fuck me like a man, sweetheart."

Kaitlyn giggled and got into position, doggy-style.  She spent a minute lining up properly, finding the right angle and teasing her mom's opening with the head of her cock.  Finally she pushed in, slowly.  They both moaned.  Kaitlyn began to thrust. The first few minutes were awkward, as she learned how to tilt her hips to keep the dildo lined up, and how to grab her mom's hips for leverage.  There was something very sexy about that, even with the awkwardness - their cheerful dedication to patiently learning this new way of fucking. Finally she got a good rhythm going.  Kathy was loving it, and Kaitlyn had a look of delight on her face.  I stood beside them, running my hands over Kathy's plump body, feeling her curves jiggle as she got fucked.

"Does it feel powerful?" I asked Kaitlyn.

"It does, Daddy!"  Kaitlyn young tits swung as she thrust her hips.  "I'm fucking her like a dog."

"Exactly like a dog in heat.  You are a bad-ass motherfucker!"

She giggled.  "I'm a mommy-fucker!"

"And you're going to make her come."

"Cool!"

I let them go on for a couple minutes, then reached under Kathy and found her dangling nipples with my fingertips.  A little pinching and pulling, and she started to come.

"Wow.  Wow!" said Kaitlyn.  "I can feel her pussy gushing... it's trickling down my leg!"

"Please!  Too much!" gasped Kathy.  Kaitlyn held steady, and I released Kathy's tits, as her orgasm ran its course.  Finally her legs gave out and she collapsed forward onto the bed, breathing hard.

"We did it," said Kaitlyn.

"Together," I said, kissing her, as Kathy moaned on the bed in front of us.  Gradually we all merged together on the bed, in a cuddle pile.

When Kathy had regained her senses, it was time for her to strap on.  We both helped her with adjusting the harness, getting it comfortable.  She picked out a dildo that was almost the same size and feel as my own cock.  At my suggestion, we blindfolded Kaitlyn, and lay her out on the bed, legs spread wide.  This was a game we had played before, taking turns eating her young pussy, and making her guess who it was between her legs, me or her mom.  It was a bit too easy for her to recognize my lips, unless I just used the tip of my tongue on her clit.  We played that game for a while until she was breathing hard, then I got in position and fucked her for a few minutes, then it was Kathy's turn.

"It's too obvious," giggled Kaitlyn, as Kathy's fake cock pushed in.  "I can totally tell that's Mom with the dildo."

"I guess it's not much of a game," I agreed, chuckling as I removed her blindfold.  "You may as well enjoy your first fuck face-to-face.  It's more romantic that way."

"Yes," said Kathy, "It is romantic. I want to look into my daughter's beautiful eyes as I drive my cock into her."  She pushed in all the way, then kissed Kaitlyn long, slow and deep, finally coming up for air.  "Do you like my cock inside you, sweetheart?"

"Yes, Mom.  It feels just as good as Daddy's cock.  But I especially love that it's you doing it to me."

"It's a special feeling that I can relate to," I said, sitting beside them.  "To be in love with a beautiful young woman, and then to fuck her."

"It's true," agreed Kathy.  "I love her as a mother, but I also love her as a lover.  I didn't think it was possible!  But I really do."  She kissed Kaitlyn again.  "I'm infatuated with you, sweetie.  I'm in lust with you."

"Oh, Mom," swooned Kaitlyn.  "I love you too.  Now, fuck me!"

Kathy resumed thrusting.  I just sat back and watched.  I had planned on us taking turns in Kaitlyn's pussy, but they were just so beautiful together, so sexy.  I didn't want to interrupt.  Kathy practiced different strokes, different angles, finding what made Kaitlyn happy.  Their plump bodies made delightful smacking sounds together, Kathy's large tits swinging as she thrust, Kaitlyn's young tits jiggling, their plump bellies sliding on each other.  For a long while, I just watched.  I was painfully hard, though, and I needed to stick it somewhere.  I felt the back of Kathy's harness, which went around the back of her waist, and around each thigh, but left the buttocks free.

"I think I could get into your ass this way," I said to Kathy.

"Yes, my ass is yours," she encouraged.  "Take it!"

"Oh, yes please Daddy!" chimed Kaitlyn.  "I want you to fuck Mom while she's fucking me... like we're all fucking together!  I'm glad I put my tongue up her butt before, so she's ready for you now... I want you to dump a load of cum in her butthole while her cock is filling me up."

Kathy stopped thrusting and pulled out a little, pushing her buttocks back a bit.  I lubed up and got in position.  Kathy was really good at anal, now, relaxing in just the right to accept the head of my cock through her sphincter, and letting me sink in slowly.  She groaned, and fell forward a bit, pushing her own cock into her daughter, as I gradually got all the way into her ass and began to thrust slowly.

It really was like fucking them both at the same time.  I thrust, Kathy moaned, her tight slippery ass gripped me, her body jiggled, her cock pushed into Kaitlyn's pussy, Kaitlyn moaned, her body jiggled.  I thrust harder, going an extra bit deeper in Kathy, and she started to gasp and moan loudly.

"Uh-oh," I said.  "I think I might be fucking her a little too hard, Kaitlyn.  But I'm so close."

"I'll shut her up," said Kaitlyn, grabbing Kathy's head.  "Suck my fat nipple, Mom!"  Kathy sucked, Kaitlyn giggled.  "Fuck her ass as hard as you like, Daddy!"

I did.  With Kathy's mouth muffled, and each of my thrusts slamming their bodies together, it was Kaitlyn that gasped on each push.  I moaned as I let go, coming deep inside Kathy.  Their bodies were still rocking and grinding together, as I slowly pulled out, sitting back to watch.  Gradually, the mother-daughter fuck slowed down, and they spent a long time locked together in a kiss.

"Kathy, darling," I said, stroking her body.  "That was beautiful.  But I've come twice already, and you've had your orgasms, but Kaitlyn hasn't had any yet.  And, that silicone cock isn't going to take her there today.  Why don't you finish her off with your mouth?"

"Yes, Mom," agreed Kaitlyn, glancing at me with a twinkle in her eye.  "I love how you just fucked me, but it's time for you to use your slutty incestuous mouth on my well-fucked cunt, and make me come so you can drink up all my girl juice."

"Of course, sweetie," said Kathy, carefully pulling out, then going down and getting busy.

"I love you, Daddy," said Kaitlyn, looking at me and sighing happily as she felt her mother's tongue.  "Would you... put your cock in my mouth while she eats me?"

I smiled back at her.  "Uh, are you sure?  My cock was pretty deep in her ass, just now."

"That's OK.  I see them do it in porn all the time.  It's sexy, right?  Ass to mouth?"

"Sure, but they're professionals.  They get their buttholes really clean before they film those scenes."

"Mom was pretty clean today.  I had my tongue up her ass earlier, remember?"

I looked down at my half-hard cock.  It did look pretty clean, just shiny with lube.

"OK, if it's something you want," I said, moving my cock to her mouth.  "I won't come again, but I'll do this for you."

"Yes, Daddy!"  Her smile was huge.  "I want you to give me ass-to-mouth because it makes me feel slutty, and I'm just about to come."

I put my cock to her lips, and she sucked it in.  Her eyes were wild, and she began to suck hard, with her hands going down to grip her mother's head.  Within a minute, I could see her orgasm sweep over her body.

----------------------------------------------

Time passed.  Kaitlyn turned 16.  Susan and I grew closer together.  One Friday night, I was at Susan's place.  We had just finished a small, gourmet dinner by candlelight.  We were two glasses of wine in, and our conversation turned to our future.

"You know, you could ask me to marry you," said Susan sweetly.

"I could," I said.  "I love you, and I love our life together."

"You have my mind and my heart, and sometimes my body," said Susan.  "And for the rest, we get to share wonderful Kaitlyn, and you have her and her mother as your two sex-servants.  It's a lovely arrangement."

"It is great," I agreed. "You could probably have Kathy, too, if you like.  She's not quite as cute as her daughter, but she is a fully-trained slut now."

"That does sound nice, but... she only has sex with you, right?  She's not like her daughter, she doesn't go for women."

"Ah...." I said.  "Well, if we're going to get married, there are a few details... secrets... that would need to come out in the open."  I smiled.  "I did promise Kathy that I wouldn't tell anyone.  So, she would need to tell you herself.  You know that I fuck them both... and you know how bisexual Kaitlyn is... and her mother wasn't naturally bisexual... but there they are in the same bed, while I'm fucking both of them, and you know how adventurous Kaitlyn is..."

Susan stared at me, her jaw slowly dropping.  "You don't mean..."

"I don't mean anything.  I can't tell you."

"Holy shit!"  Susan was cute when she swore, since she rarely did so.  "You're not just fucking them, you've gotten them to do it with each other?"

"Hypothetically," I said.  "How would you feel if that was true?"

Susan sat in stunned silence for a minute, her expression wide with amazement.  "I... I think... that's the craziest thing I've ever heard.  And totally absurd.  And," she smiled, "totally hot."

"If you want in on this secret, you'll have to make it worth her while," I cautioned.  "Kathy does have some things that she wants.  Simple things, really.  She wants a personal trainer at her gym, she wants private school for Kaitlyn.  Things like that."  I smiled.  "These are things we could easily afford."

"Fuck, yes."  Susan was slightly tipsy, but she never swore so much.  "Let's do it!  I could get the mother and daughter both serving me at the same time?  And... I could watch them do it... with each other?"

"I can neither confirm nor deny that that is a real possibility."

"Wow.  Just, wow."  Susan stood up, reaching for her mobile.

"I wouldn't just ask her over the phone," I said smiling.

"I'm not.  I'm calling Kaitlyn.  Our little conversation has gotten me too damn hot.  I want to have sex with you, and it's always better with her."  She punched a number on speed-dial.  "Hi, darling.  Get your ass over here.  Yes.  Take a Lyft.  See you."  She hung up.

Twenty minutes later, dinner was cleared away, and we were out on Susan's balcony, with our third glasses of wine.  I heard Kaitlyn letting herself in.  Of course she had her own key to Susan's place.  Kaitlyn came and found us on the balcony.  She wore a T-shirt and skirt, no bra.  Susan sighed and pulled Kaitlyn to her, embracing and kissing her deeply.  I reached down and felt under Kaitlyn's skirt, to find she also had no panties.  Susan finally broke the kiss, and passed Kaitlyn to me.  We kissed hot and deep.

"We're talking about getting married," said Susan.

"Cool!" said Kaitlyn.

"I'm all turned on.  Eat my cunt, darling."

"Of course!" giggled Kaitlyn, dropping to her knees, pushing aside Susan's elegant dress, and pulling down her panties, her eager face pushing forward.

"Out here on the balcony?" I asked, smiling at Susan.

"I'm feeling a little wild," she agreed.

I moved in closer.  Susan and I embraced and kissed sweetly, as Kaitlyn was down there busy.  Susan moaned into my mouth.  I was able to push a shoulder strap off, expose one tit, and play with Susan's nipple, all without breaking our kiss.  I knew Susan only enjoyed nipple play when she was completely turned on, and this was clearly the right time.  Her breasts were modest sized, but her nipples were large, easy to grip and manipulate.

This went on for a long, lovely time.  Susan got hotter and hotter.  I knew she didn't orgasm easily in a standing position, but finally she got there, coming hard on Kaitlyn's mouth.

"Do you want to fuck me, sweetheart?" asked Susan.  "There's never a better time."

"I'd like to fuck both of you, but not here on the balcony." I laughed.  I herded them both inside, onto the master bed.  They tumbled together, making out.  I caressed them, and my fingers found their way between Kaitlyn's chubby thighs.

"Is this pussy available?" I asked.

"Yes, Daddy, always," giggled Kaitlyn, using one arm to lift her leg, making room for me.  "My tight little teenage pussy is always available for you to fuck it with your big Daddy-cock."

I moved to kneel over her, and lined up to thrust, finding her already wet.  I fucked her as she and Susan made out, sucking each other's nipples.  Susan reached down and was able to get her fingers on Kaitlyn's clit, stroking it with great experience, knowing exactly how Kaitlyn liked it.  We lasted a long, wonderful time that way.  At one point, I brought my right hand up for Kaitlyn to suck, wetting it, then moving it down to push one finger into her ass.  Kaitlyn came that way, with her tit being sucked, her clit rubbed, her pussy filled, and her ass fingered.

"Finish inside me?" asked Susan, watching me thrust as Kaitlyn came.  "I'd like to feel you ejaculating in me."

"Sure thing," I said.  "I'm close, so it will only be a minute."  A minute later, I carefully pulled out of Kaitlyn, and pushed into Susan's pussy, where I so rarely went.  Kaitlyn came up to suck on Susan's tits.  It took me a minute to regain my rhythm and momentum, but soon I was kissing Susan while draining my balls inside her.

"Can I suck you clean, please?" asked Kaitlyn.

"Oh, darling.  You are so sexy and naughty," said Susan.  "Of course you can clean me up."

I pulled out, Kaitlyn got down to suck me clean, then she went in to eat that creampie.  She kept going until Susan came again.  After that, we all cuddled together on the bed, then Kaitlyn kissed us and quietly left.

-----------------------------------

I wasn't present when Susan sealed the deal with Kathy.  Apparently, she invited them both over to her place, and very carefully raised the prospect of what she could offer, in exchange for gaining Kathy as a second sex servant, and to experience Kathy and Kaitlyn together.  It must have gone well, because I heard that they all had sex together that first time.  I wasn't there for it, but Susan later raved to me about how excited she was, the first time she got to command Kathy and Kaitlyn to perform lesbian incest for her.

-----------------------------------

The occasion of my engagement to Susan was when we called them over, for our first time together as a foursome.  Susan and me, and our two servants, in Susan's giant master bedroom.

"I love you, Mike," said Susan, pulling me to her side.  We were already half-naked and cuddling in her bed.

"I love you too," I said, as we kissed.  "We've been sharing Kaitlyn together for a few months, but this is the first time we've had both of them to use together.  What do you think I should do with our servants, today?"

"I want to watch you fuck 'em.  Fuck 'em deep in all their slutty holes, but then save your orgasm for me."

"That sounds fun, but I think they should warm each other up a bit first?"

"Good idea!  Their lezzie incest is the hottest thing ever."

"OK, dear slutty servants," I said.  "Are you ready to perform for us?"

"Yes, Mike," said Kathy and Kaitlyn, standing at the foot of our bed.  They wore matching outfits, their blouses fitting snugly onto their plump bodes, short skirts on their plump thighs.  They were simply holding hands, sweetly, waiting on us.

"Start slow.  Kiss each other tenderly, sweetly.  And tell us how much you love it."

"Yes, thank you," said Kathy, "I love to kiss my daughter as my lover."  She took Kaitlyn into her arms, their bodies melting together, their mouths meeting.

"So beautiful," said Susan with a sigh.  "And so kinky."  We watched together as the gentle kisses grew more urgent, deeper.

"Mike," asked Kaitlyn, breaking the kiss, "Can I please suck on my mom's nipples?  That gets her so turned on."

"Do it," I encouraged.

"Oh, fuck yes," said Kathy, eagerly unbuttoning her blouse.  There was no bra.  "Here, sweetheart, suck on my hot tits.  Mommy's titties are always hot for you."

"You trained them to talk like that, didn't you," remarked Susan.

"I did," I admitted.  "At least, I gave them some tips.  They've invented a lot of dirty talk themselves."

"I love my mom's big, fat tits," said Kaitlyn, squeezing them in her hands sucking away at them.  "I love the feel of her big nipples in my mouth.  I love how just a little incestuous titty-sucking gets her turned on and makes her pussy wet."

Susan and I gently caressed each other as Kathy and Kaitlyn progressed.  Sucking and pulling on each other's tits, slowly undressing each other, blouses open, skirts unsnapped, panties pulled down with teeth, posing and spanking, fingering and teasing.  Finally, begging to be allowed to eat each other's pussies.  When we gave them permission, they tumbled onto the foot of our big bed, and got busy slurping away at each other.

Susan released me, urging me to fuck them.  I did so, giving Susan a good show.  I fucked Kathy as she ate Kaitlyn, fucked Kaitlyn as she ate Susan, fucked Kathy's mouth as she sat on Kaitlyn's face.  At one point, they were working together on Susan, with Kaitlyn's tongue on Susan's pussy, and Kathy's tongue up Susan's ass.  I was behind Kathy, giving it to her hard, doggy style.  I heard the distinctive sound of Susan having one of her quiet orgasms, then Kathy was coming on my cock, her noisy orgasm muffled by having her face between Susan's buttocks.

"I'm very close," I announced.

"Inside ... me!" gasped Susan, pushing our servants away in her orgasmic glow, and spreading her legs for me.

I moved onto her and sank in.  Susan didn't really know how to fuck back, but she didn't need to.  I was so close, and so glad to be actually fucking my sweet girlfriend, that I exploded inside her in under a minute.

"May we please clean you up?" asked Kathy.

"We want to suck up every bit of cum," agreed Kaitlyn.

I pulled out.  Kathy moved into slurp Susan's pussy clean, and Kaitlyn did her best to hoover the last bits of cum from my balls.  Then Susan and I cuddled through the aftermath of her orgasm, while Kathy and Kaitlyn, without even being asked, spent some time in a long, sloppy kiss, with my cum passing between their mouths.

"You're ready to go again, aren't you?" Susan asked me, her hand on my erect cock.  "I've seen you do Kaitlyn in the ass before, but I've never seen you do it to Kathy."

"Sluts, present!" I commanded.

Kathy scrambled up onto her knees, facing away from us.  Kaitlyn giggled and knelt by her mom's big ass, smiling at us as she used both hands to spread her mom's butt cheeks.

"See?" she said, spreading and pointing.  "Here is my mom's big fat pussy, where I was born from.  And here, is her cute little butthole, where Daddy likes to shove his cock.  We got it nice and clean and ready for you, Daddy.  See?"  She brought a couple fingers to her mouth to wet them, then pressed them into her mother's ass, then brought them back to her mouth to suck.  "Nice and clean and fuckable."

"Eat your mom's ass," instructed Susan.  "I want to see how deep you can push your tongue inside her."

"Yes!" enthused Kaitlyn, "I love eating my mommy's ass."  She dove in.

Kathy turned a little to face us.  "God, I love this.  I don't know how to thank you.  I was always a slut, but you turned me into a lesbian incest slut.  If you hadn't done that, I would never have known this wonderful feeling, my own daughter's tongue squirming around in my ass.  I know you love fucking my daughter's tight teenage butthole, and I know that I don't have any holes in my body that can compete with that.  But I hope that I can give you some pleasure if you would fuck my ass really hard and really deep?"

"Kathy, my pet," I said warmly, "Your holes are great.  Your skill with your pussy muscles, and your deep-throating is phenomenal.  You have nothing to apologize for.  And you've really gotten good at anal.  I will give it to you, hard and fast."

"And deep?" she asked.  "Don't hold back.  I want you to shove your cock so far up my ass that I can feel it moving my guts around."

"Wow," said Susan.  "Her dirty-talking game is strong."

"It is," I agreed, "and now I'm going to give it to her."  I moved over and got in position. Kaitlyn moved aside and helped guide my hard cock through her mom's sphincter.  In one long hard push, I was balls-deep.  Kathy moaned.  I grabbed her wide hips and started to fuck.

Kaitlyn went over to Susan.  They kissed and cuddled for a bit as they watched me ass-fucking Kathy, then Susan got turned on again, and reached for an anal toy on the beside.  Soon, Kaitlyn was down between Susan's legs, sucking Susan's clit as she gently worked the lubed toy in and out of Susan's ass.  Susan was moaning, both hands on Kaitlyn's head.  Susan and I looked at each other and shared a smile.

"Are you going to come in your slut's ass?" asked Susan.

"I might.  She's so hot inside and her ass is squeezing me just right."

"Or you could finish in my mouth," suggested Kathy, panting with exertion as she took my thrusts.  "You could pull it out my ass, put it in my mouth, make me suck it clean, then fuck my throat and shoot your cum right into my stomach as I choke on your cock."

"That's a nice idea," I agreed.

"I have a better idea," said Susan, beside herself with lust.  "Put in my ass!"

"I've never been there before," I said.

"No man has ever been there before.  I can't believe I'm even saying this, but, I love you, and I'm ready.  She's got my toy in there and it's about the same size as you.  If I can take it, I can take you."

"We can help!" offered Kathy.

"Then let's try it," I agreed.

I gently pulled out of Kathy's ass.  Kaitlyn removed the toy and moved aside.  Susan instructed them.  First, Susan spread her legs wide and had both sluts take their turn eating Susan's ass.  Then, the sluts worked together to suck me clean.  Then, Susan had them come up and kneel on either side of her.  Kathy sucked Susan's right nipple, while Kaitlyn sucked Susan's left nipple.  I got between Susan's legs, tilted her hips up for her comfort, and lined myself up with her sphincter.  Kathy and Kaitlyn both reached a hand down to play with Susan's pussy and clit.

"I'm going to go slow," I said.

"Go as slow as you want," moaned Susan.

I spent a few lovely minutes pushing myself gently into Susan's ass.  Going slow, letting her get used to it.  Pulling out and applying more lube, then going a little deeper.  I was hard as a rock, and she was beside herself with lust, her nipples sucked, her pussy stuffed with fingers, her clit rubbed, and my cock gently invading her rectum.

"That's it," I finally declared.  "I'm all the way inside you, darling."

"Oh, my love," said Susan, gasping with lust.  "Will you... will you marry me?"

"Yes." I managed to say.  "Yes, Susan.  I will marry you."

"Good!"  She almost giggled.  "Now wait till I come again, then you can be the first man to shoot your sperm up my ass."

"As you wish," I said with a smile.

We all worked together to drive Susan toward an enormous orgasm.  It was hard for me to hold back, but I did manage.  Her convulsions helped set me off, and I gave a few quick thrusts before draining myself, hard and deep up her ass.

We all untangled, then the servant sluts left us to go sleep together in their room down the hall, while Susan and I held each other and kissed and cuddled each other to sleep.

----------------------------

The following morning, I awoke to the feeling of an enthusiastic mouth sucking my erect cock, under the covers.  With my eyes half-open, I felt around in the bed.  Susan wasn't there.  I felt down between my legs, and the shape of the head sucking me told me it was Kaitlyn.  I pulled her up to me, saw the smile on her face, and tickled her until she giggled, then kissed her.

"Oh, Daddy," she said.  "I'm so happy for you.  You and Susan-Mommy really love each other.  But, you know... I'm kinda sad too."

"Why is that, sweetheart?"

"Well, it's just that... I always kinda dreamed that you would marry my real mom.  Then you'd be even more my real Dad, and we'd always be together.  I know, I know, my mom is just your servant, and you don't love her that way."

"Oh, darling.  You and your mom are special to me, and Susan absolutely adores you.  And being married doesn't really affect whether people stay together forever.  You and your mom can leave us whenever you like, but Susan and I would be crazy to tell you to leave.  Two trained sluts like you are a rare and precious treasure.  I hope you never leave."

"Oh, Daddy!"  She smiled and giggled, and we kissed some more.  "In my even wilder dreams, I kinda hope that you would marry me.  I know that Mom isn't that smart, you don't have that kind of connection.  But I'm smart.  And in my fantasy, Susan is still your girlfriend, and my mom is our servant, and I sleep with you every night, and we do every kind of crazy sex with each other, all the time, and I'm your wife and your perfect slut.  I know it's totally crazy and I'm too young and it doesn't make any sense.  I'm just telling you what's in my heart."

"Kaitlyn, my darling, that's really sweet, and I'm glad you told me.  Don't worry, even when Susan and I get married, you'll get lots of my time and attention, and all the sex you want."

She kissed me.  "Thank you, Daddy.  How about sex now?"  She gripped my hard cock, slowly stroking it, with so much more experience and confidence than one would expect from a 16-year-old girl.  "There's one hole you didn't fuck last night.  My ass is lubed and ready for you."

"OK, my little slut.  How you do want to take it?"

"I want to be face-down.  If we do it face to face, it's more romantic, and I need to be OK with unromantic sex, because you're marrying Susan-Mommy.  So I'm going to turn over, and you just ram it into me, so I can be your sex toy, just a hot tight hole, just a place for you to dump your cum.  You can fuck my tight little butthole as hard as you want, Daddy. And I also have a special treat."  She reached for the nightstand, and pressed a button.  I heard a buzzing sound.  "I have one of Susan-Mommy's skinny remote-control vibes in my pussy.  It feels great to me, and you'll feel the vibration too, when you're up my ass."

"You are so much more than a sex toy," I said.  "You are creative and delightful and I cherish having you in my life.  But sure, I can give it to you rough and unromantic if that's what you want right now."

"I do.  Rough and unromantic.  I want to be a sex doll for you, a naked teenage girl you just found in your bed, you can shove me around and ram your cock into my tightest hole, just for your own pleasure."

  I pulled back the covers and rolled her over onto her front.  She giggled and reached back with both hands to spread her wide, fat buttocks.  I straddled her thighs, guided my cock to the right spot, got the head in, then lay down on top of her and pushed into her lubed ass.  With the size of her buttocks, I couldn't really fuck too deeply this way, but it hardly mattered.  Her little asshole was crazy tight and slippery and the vibe in her pussy was buzzing.  She gasped and moaned with each hard thrust, her plump body jiggling and rocking, the weight of my body pressing on her.

The door to the bedroom opened and Kathy came in, wearing only a loose nightrobe.  She smiled when she saw me on top of Kaitlyn, coming closer to get a good look.

"Good morning, Master!" she said happily.  "I see my daughter-slut is taking care of your morning erection."  Kathy kissed me deeply, then ran a hand down my back, reaching between my legs to feel my balls.  "Are you using her ass?"

"Yes. And she's got a vibrator in her cunt."

"Ooooh!"  Kathy moaned, caressing our bodies.  "I can feel it vibrating through you.  That makes me horny."

"Here, I'll sit up a little so that you can watch my cock go in."  I pushed up a bit, and Kathy bent in to watch.  "She said she wanted it unromantic, just roll her over and ram it in."

"Yes, she told me all about it.  She wants you to remind her that she's your servant."  Kathy smiled at me, and loosened her robe, letting her fat floppy tits spill out.  "I think it's hot.  Put my little girl in her place.  It's making me wet."  She spread her legs a little so that she could push her right hand down between her legs.

"If you're turned on by it, then finger-fuck yourself," I suggested.  "And feed me a tit."

Kathy moaned and used her left hand to lift one of her fat tits, feeding the large nipple to my mouth, while her other hand was busy in her pussy.  I sucked and gently bit Kathy's tit, which made her moan harder.  I fucked Kaitlyn's ass hard, which made her moan too.  It was nice, and I was getting close to coming.

"I want us ... to be your sluts forever," gasped Kathy.

"Susan and I want that too," I agreed, my voice muffled by the big nipple in my mouth.  "Now, where should I dump my morning load of cum?"

"You should dump it in my daughter's hot tight little asshole," gasped Kathy, "but I would really like you to come in my mouth, too!  Maybe you can show me what a nasty, submissive anal slut mommy I am, by pulling your cock out and shoving it into my mouth, so I can suck the last of your cum out of your balls while tasting my daughter's ass?"

I grunted my approval, and started ejaculating into Kaitlyn.  Kathy noticed me coming, and gasped with excitement, pushing her face down to Kaitlyn's butt, opening her mouth eagerly.  I pulled out of Kaitlyn's vibrating hole, my hot cock bouncing up into Kathy's mouth, where it was immediately sucked hard.  It was intense, and I let Kathy keep sucking for a minute, until she had her own orgasm.

I pulled back, and rolled Kaitlyn over on the bed.  She was smiling at us.

"Your daughter has been a very good servant slut this morning," I said to Kathy.  "Go ahead and kiss her, suck on her tits, then move the vibrator to her ass, and suck your daughter's cunt until she comes on your mouth."

"Yes, sir," said Kathy, bending in to kiss Kaitlyn.

"After that, come make us breakfast," I said, leaving them on the bed.

------------------------------

The wedding was a small affair, Kathy and Kaitlyn were bridesmaids.  Immediately after the wedding reception, the four of us flew to the Carribbean to a deluxe resort for our honeymoon. Our servants had their own hotel room, to keep up appearances.  Neither of them had ever been to such a fancy hotel, or ever been on vacation to a tropical beach with warm, crystal-clear waters.  They were absolutely delighted, and we let them play and enjoy the resort together, but of course, their main reason for being there was to service Susan and I, in particular, sexually.

Hanging out at the resort was pure hedonism.  At home, Susan and I had our jobs. Kathy and Kaitlyn both had school, and we usually only had one or the other of them over at our townhouse.  In our hotel suite, we had both available nearly full-time.  When they weren't out enjoying the beach or spa, they were available to us.  We had most of our meals delivered via room service, which also allowed them to drink as much alcohol as they wanted; Kaitlyn being 16 years old meant she couldn't drink publicly, but in our room's full bar, she delighted in making fancy mixes drinks for everyone, and knocking back plenty of them herself.

Do you want to know what's even more fun than having a plump, cute mother and daughter team that are well-trained, subservient, dirty-talking incestuous sluts?  Having them really drunk together.

One morning, we were sitting in our suite, at the breakfast table.  The bright tropical sun shone in the large windows, and the table was laid out with fancy breakfast that had just been delivered.  Susan and I were relaxed in our bathrobes, Kathy and Kaitlyn were completely naked.  They had woken us up that morning, by crawling into our bed, and giving us oral sex, Kaitlyn eating Susan, and Kathy deep-throating me.  Now we were drinking and snacking at the breakfast table.  Kaitlyn was mixing champagne and orange juice to serve us mimosas, and was giggling as she drank a lot of them herself.

"I guess I should eat some food, too," said Kaitlyn, giggling as she reached for a slice of French toast.

"I've got a better idea," said Susan, smiling.  "You can't use your hands, or eat anything, unless you eat it off your mom's body."

"Well, I've got these," said Kathy, helpfully holding up her breasts.  "If I push them together, it kinda makes an eating surface."

"Can I have French toast?" asked Kaitlyn.

"Sure, honey."  Kathy tore off a bite of French toast, and placed it between her breasts.  Kaitlyn giggled and pushed her face into her mom's cleavage to eat the toast.

"Needs some butter and syrup," she said.

"Here," said Kathy, dipping one of her nipples into the whipped butter, and the other into the syrup.

"Oh, this is fun to watch," giggled Susan.  We nibbled our own breakfast as we observed Kaitlyn eating breakfast off her mom's tits and nipples.

"I want a shrimp," said Kaitlyn, drunkenly pointing to a dish of shrimp cocktail.

"Put a shrimp in your pussy, mom-slut," said Susan.

"Oh.  Yes!"  Kathy laughed, reached for the shrimp, then pushed back from the table a bit, so that she could spread her fat thighs and push the shimp deep inside herself.

"How am I supposed to get that, without using my hands?" asked Kaitlyn.

"You're right, it's pretty challenging," laughed Susan.  "Mom-slut, stand up and lean over the table, so that your daughter can push her face into your pussy from behind."

They got into position, Kathy's large tits resting on the table as she bent over and pushed back her hips, Kaitlyn eagerly mashing her face between her mother's plump buttocks, her tongue reaching.

"Ooooh, this feels nice," giggled Kathy, "It feels like she's trying to crawl up my pussy, back into my womb."

"I got it!" said Kaitlyn triumphantly, her face dripping with pussy juice, chewing on her shrimp.

"This is fun. Let me help," I said, getting up and finding another shrimp, and three grapes, pushing them deep into Kathy's pussy as she remained bent over.  Susan and I sat back and watched the spectacle.  The grapes proved to be difficult.  Kaitlyn couldn't breathe with her mouth and nose that deep in pussy, so she had to come up for breath from time to time.  She was breathing hard, and Kathy was groaning with lust, by the time she was able to lick and suck out the last grape and eat it.

"Good job, Kaitlyn!" I enthused, "You've really got your mom all turned on.  Would you like to get fucked, mom-slut?"

"Yes, please!" gasped Kathy.

"I think daughter-slut should do it," said Susan.  "Go get the big strap-on."

"Oh, goody!" giggled Kaitlyn as she dashed naked to the other room.

Susan and I continued to nibble at our breakfast.  Kaitlyn came back, with the strap-on harness around her waist supporting the extra-big silicone cock.

"Here you go, Mommy!" she giggled, lining up and pushing into Kathy from behind.  "A big, fat, hard cock to fill up your big, slutty pussy!  Damn, you're so wet, you're just taking it all."

"Oh, yes!" gasped Kathy.  "Oh, that's so good.  Nobody fucks my pussy like you, sweetie."

"You love it when I fuck you," giggled Kaitlyn, holding onto her mom's hips and thrusting steadily, "because you're a big fat incest slut.  You're juicing up on my big fat cock because you love getting a hard fuck from your own daughter."

"I do love it!" gasped Kathy.

"Wow, our little slut is really into it," I noted.  "Look at those adorable fat tits bouncing as she fucks her mom."

"She really is doing it hard, isn't she?" agreed Susan.  "I know the big slut can take it.  And little slut is really cute and sexy, the way her tits bounce.  Hey girl, you're a sexy mother fucker!"

"Yes!" giggled Kaitlyn.  "I am a sexy mother fucker!"

Susan and I just casually nibbled our breakfast and sipped our coffee, as they kept at it.  Kaitlyn giggling, Kathy moaning as she gradually built up toward an orgasm.  When she finally came it got a little crazy.  Kathy is pretty loud, and her arms wobbled, jostling all the things on the breakfast table. Kaitlyn cried out with excitement as she fucked harder, riding her mother all the way through it.

"That was really something," said Susan, as Kathy finally wound down and they disentangled.  "Light entertainment for our morning, indeed."

"Does Daddy want to fuck us now?" asked Kaitlyn.  "I wanna go swim and sunbathe, but Daddy comes first."

"Go ahead, sex later," I said, laughing.

--------------------------------------

Having our servant-sluts with us made my honeymoon with Susan just that much more pleasurable.  Waking us up each day with oral sex was lovely, having tight holes to casually shove my cock into was very convenient.  Susan liked having her pussy eaten a lot, not just at morning and night, and not always to orgasm, but just for the thrill of grabbing the nearest servant-slut, pushing her down, and riding her face.

We had a lot of special moments. One night Susan and I went out on the balcony, with glasses of champagne, to stand in the moonlight and look out across the bay to watch the hotel lights shining and reflecting in the water, the soft warm air around us, holding each other, kissing and talking.  A lovely, romantic evening, you might say, but what made it extra pleasurable was Kaitlyn, on her knees, kneeling behind Susan, doing her best to push her tongue up Susan's ass, while I had Kathy kneeling behind me doing the same thing.

Our suite had an enormous hot bath, big enough for several people, which Susan enjoyed laying in, letting our servant-sluts wash her body.  I had a lot of fun figuring out how to fuck our sluts in the bath.  It's not as simple as you might think.  For starters, bathwater isn't a very good lubricant.  On the other hand, the water provides some buoyancy, so that some positions are actually easier, especially with a plus-sized woman like Kathy.  Out of the bath, it wasn't very comfortable for Kathy to sit in my lap, either facing me or facing away, with my cock in either her pussy or ass.  Her weight was just a bit too much on me.  But in the bath, it worked!  The only challenge was maintaining lubrication.  One afternoon, after the servant-sluts had a nice time on the beach, I had them go fill the bath, then went to to go find them.

"It's lovely hot water," said Kathy, smiling as she saw me come in.  They had their arms around each other, and Kaitlyn was sucking on her mom's tits.

I kicked off my boxer shorts and stepped into the tub.  Casually, I took Kathy's face in my hands and pushed my half-hard cock into her mouth.  She moaned and sucked.

"Do you want a double blowjob, Daddy?" asked Kaitlyn cheerfully, watching me fuck her mom's face.

"Actually, I want to try what we talked about earlier, the sitting anal?"

"Oh, yeah!" giggled Kaitlyn.  I pulled out of Kathy's mouth, and we helped her get onto her knees, leaning over the edge of the tub, pushing her buttock back and up just enough to get them above the surface of the water.

"Before we lube her up," asked Kaitlyn, "Can I please eat my mom's pussy and ass a little?  You know how much I love sucking on her pussy while my nose is in her ass and her butt-cheeks are squeezing my face."

"Sure, little slut," I said chuckling.

Kaitlyn grabbed her mom's buttock and dove in.  For a couple minutes, I let her slurp while her mother moaned.  Then I reached for the bottle of lube that was already conveniently next to the bath, and together we lubed up my cock and Kathy's ass.  Anal sex is never instant, there is always a slow approach, so I took a couple minutes to gradually get myself balls-deep in her.  Once I was in and she was ready, we carefully sank downwards down into the tub.  I was now sitting comfortably, Kathy in my lap, her fat body buoyancy reducing her weight, making it easy.  Her tits floated a little in the water.

"This is wonderful," I said.

"It is!" agreed Kathy.  "You actually feel really good in my ass."

"Rock your hips a little, and I bet we can fuck a little in and out, without losing our lube connection," I suggested.

Kathy rocked, and sure enough it worked well enough, I could feel her tight ring milking my cock.

"How can I help?" asked Kaitlyn.

"Play with her clit," I suggested.  "I'll pull on her nipples."

We spent a long, happy time like that.  Kathy rocked her hips, moving me just slightly in and out of her ass. I had Kathy's tits in my hands.  Kaitlyn was busy manipulating her mom's pussy and clit under the water, and kissing me, and kissing her mom.  Kathy was moaning softly, her arousal high, her orgasm close by.

"Kathy," I said, using her real name instead of our pet slut terms, "Do you remember the first day that you were behind on the rent?  When I said, you'd be evicted unless you helped me come in your daughter's mouth?"

"I do remember," she moaned.  "We've come a long way since then, haven't we?"

"I remember," said Kaitlyn.  "You made mom kiss you, and you played with her tits, while I tried sucking you for the first time, and I wasn't good enough to make you come, so you jacked yourself off and came in my mouth and I swallowed it."  She giggled.  "It didn't taste good, and it still doesn't taste good.  But now I love it because I'm your servant slut-girl."

"And Kathy, remember the first time you really, truly ate your daughter's pussy.  You were so nervous, so reluctant.  We eased you into it real, real slow.  You had kissed each other, you had sucked each other's nipples, Katie had even eaten your pussy, twice, and you accepted it.  But you actually doing it to her was a big step."

"It was the biggest step," agreed Kathy.  "Once you got me to do that, all my resistance was gone.  I really became your slut then, your servant."

"There are still some lines we haven't crossed, though."

"Really?"  She giggled.  "I'm pretty sure that I've done absolutely everything a slut can do."

"Not even close,"  I said.  "And I want you to realize, that every time we've taken you across a line, you've gotten used to it, and you even learn to love it.  Girl slut, stand up in the tub in front of us."

Kaitlyn stood up.  I reached around to take over the job of playing with Kathy's clit under the water.  Kaitlyn's wet, dripping body was right in front of us, her pussy right about at the level of her mom's mouth.

"Eat that pussy," I said.

"This isn't a new line to cross," giggled Kathy.  "I absolutely love eating my daughter's sweet, wet little cunt."  Her mouth moved forward, pushed its way between Kaitlyn's chubby belly and thighs, and made contact.  I heard slurping sounds.  I played with Kathy's clit, feeling her get close to orgasm.

"This is really nice, Daddy," said Kaitlyn.  "Making my mommy-slut eat my pussy while your cock is up her ass, it's nice, but she's right, it isn't new."

"True," I said.  "But remember what I talked about earlier?  Let's do it now."

"Oh!  Yeah, Daddy!  You're so kinky!" giggled Kaitlyn.  She reached down and roughly grabbed her mother's head, holding it tightly. And then she started to pee.  It ran down Kathy's chin, splashed on her chest, ran in rivulets down her plump tits.

Kathy reacted in shock, trying to pull her face back, but Kaitlyn held it firmly.

"Drink it!" I said firmly in Kathy's ear.  Her mouth moved slightly down to capture Kaitlyn's urethra, and while her body was trembling, we heard and felt her swallowing.

"She's doing it!" giggled Kaitlyn.  "I didn't think she would.  Oh, I'm so happy!  Good mommy!  Drink all my pee, mommy-slut! Now you're Daddy's pee-slut, too!"

I ran my fingers quickly over Kathy's clit, then plunged them down into her pussy.  She started coming hard, her pussy squeezing my fingers, her sphincter squeezing my hard cock in her ass.  She managed to keep swallowing, mostly.  Some pee still ran down her neck and tits.

"That's a good slut!" I said encouragingly.  "Keep sucking.  That's the best way to get used to your new kink, do it while you're coming."

Finally, Kaitlyn ran out of pee, and Kathy's orgasm ran its course.  Kaitlyn let go and slid down to hug us in the water.

"I can't believe I just did that," gasped Kathy.  "That you made me... do that!"

"Good slut," I said soothingly.  "It will be easier, the more we do it."

"More?" she asked.

"Of course, Mommy," said Kaitlyn, "You're going to be our pee-slut, from now on."  They kissed, then she looked at me.  "Daddy, you didn't come in her ass, did you?"

"Not yet, sweetheart."

Kaitlyn batted her eyes at me and said "I want to swallow your cum, Daddy.  Can you ass-to-mouth me?  Lift Mommy's ass up to the edge of the tub, fuck it hard, and use my mouth."

"Sure, sweetheart.  I can ass-to-mouth you."  I helped Kathy up, standing in the tub on wobbly knees.  Kaitlyn lay her smiling face on her mother's wide buttocks, opening her mouth so that her mouth-hole was right above her mom's asshole.  I sank my hard cock deep into Kathy's ass, making her groan, then pulled out and pushed it into Kaitlyn's sucking mouth, making her moan.  This was a familiar pattern for us, and I knew just how hard I could use Kaitlyn's mouth without making her gag.  For fun, I went from Kaitlyn's mouth to Kathy's pussy, then Kathy's ass, then back to Kaitlyn's mouth.  I had been close to coming for a long time, so finally I had to just hold myself in Kaitlyn's mouth and let my balls empty their sperm for her to enthusiastically suck down.

----------------

Over dinner that night, we told Susan about what happened in the tub.  Susan was surprised, a little shocked, and a little turned on.  She wanted to see it for herself, and suggested they do it right there at the dining table in our hotel suite.  I didn't want to make that much work for our room cleaning staff, so after dinner was over, we went into the bathroom, filled the large tub, and all four of us got in.  We had Kathy and Kaitlyn kiss and finger and lick each other to warm them up, then we watched as Kaitlyn stood up and got into position.

"Remember the next step," I told Kathy, "on any line you're crossed?  It's not enough to submit to it.  You need to learn to ask for it."

"Yes, of course," agreed Kathy.  "I am ready."  She paused, looking at each of us, looking up at Kaitlyn's dripping-wet naked body, then back at me.  "I'm ready to practice being a pee-slut."

"Beg," said Susan.

"Yes!  Please, mistress.  I love being a sex slave to you and my master.  I love being an incestuous anal slut.  May I also be a pee-slut?"

"Yes, mom-slut," said Susan.  "What do you want right now?"

"I want my daughter to pee all over my naked body.  I want her to pee on my tits, and pee on my face."

"And in your mouth?" I suggested.

"Yes.  I want her to pee right into my mouth, and I want to drink it all, and I want you to watch me do it."

Kaitlyn stood and peed all over her mom's face and tits, then directly into her mom's mouth.  When she ran out of pee, Kaitlyn just pushed her pussy forward and rode her mom's face and tongue.

"That's so much fun!" said Kaitlyn, giggling.  "I love that you've made Mom into a pee-slut."

"It's fucking hot," agreed Susan.

"I assume you are also ready to become a pee-slut?" I asked Kaitlyn.

"I guess so, Daddy.  I got used to drinking your sperm, and that still doesn't taste great.  I could get used to pee, too."  She wrinkled her face and smiled.  "Could we ... um, before I drink it, could we just try, um, peeing on me?"

"Of course, my pet," I said warmly.

"I'm ready to pee on you, right now," said Susan lustfully.

"Go ahead," giggled Kaitlyn, holding out her tits.

Susan stood up in the bath, moved to straddle Kaitlyn's torso, and peed.  It went on Kaitlyn's chin and neck, and pooled between her tits.  Kaitlyn smiled and reached into the stream, catching some pee in her cupped hand.

"It's hot," she said.  "I mean, it's sexy, but the temperature too.  Do you want to pee on me too, Mom?"

"Sure, sweetheart," said Kathy, moving up to get in place.  "Close your eyes and mouth, and I'll do it right on your face."

"OK!  Cover me in mommy-pee!"

Kathy must have really needed to go, because Kaitlyn was soon drenched, her hair, her face, her shoulders, her tits.

"Now Daddy, it's your turn to pee on me," said Kaitlyn.

"OK, but I want to try something.  Sit up on the edge of the bath, spread your legs, and let your mother open up your pussy.  I'm going to pee on your clit."

"Oh!  OK."  They got into position, with Kathy's hands stretching her daughter's labia wide open.  I was half-hard from watching all the play, so it was a little tricky for me to start my flow, but soon I was blasting Kaitlyn's adorable little clit.  She moaned and giggled.  My pee splashed all over her vulva, pooling into her open pussy.

"Kathy-slut, it's time for you to taste my pee.  Drink it all up from your daughter's pussy."

"Yes, sir!"  Kathy got in there and slurped and swallowed the pee, making Kaitlyn gasp and giggle.

"That's just amazing," gasped Susan.  "I'm so turned on, I need all three of you to take me to bed, right now."

We got out, dried off, and ran naked to the huge bed, splayed out on the soft sheets, and spent the next hour using everything we had to make Susan come, again and again.

-------------------

By the time our honeymoon was over, both Kathy and Kaitlyn were completely comfortable with taking pee anywhere, anytime.  Kaitlyn drank it directly from my cock for the first time just as she was having a huge orgasm, so that helped to cement her positive relationship to it.

We flew home, and made some adjustments to our life together.  Susan sold her apartment, and we bought a huge new house together, with abundant rooms for all our interests, and of course our two servants.  Kathy finished her master's degree, and started her own business.  Kaitlyn began her senior year of high school.  Kaitlyn also developed a major interest in food, taking over most of the cooking in our house and talking about going to culinary school after she graduated.  Through diet and excerise, both Kaitlyn and her mom lost a fair amount of weight, but their bodies never fully lost their chubby curves that made them so plush to fuck.

Our servants never tired of finding new, fun ways to play, sexually.  We build a BDSM playroom, though it was mostly Kathy that liked to receive, and usually pretty gentle.  They spent a lot on clothes, for fancy ways to dress up and have sex.  They came up with fun role-playing, like when Kaitlyn would dress up elegantly and Kathy would dress as a school-girl, and they'd pretend their relationship was reversed, during the course of a sexual workout with lots of lesbian incest and taking my cock in all holes.

My single favorite thing to do with my servants was to surprise them with casual sexual demands, especially when they were trying to do something else.  Cornering Kathy while she was trying to have a business call, opening her blouse to suck her tits, pulling down her panties and fingering her to wetness while she was trying to focus on her call.  I loved catching Kaitlyn in the kitchen, pulling up her skirt and fucking her while she was trying to cook.  I'd follow either of them into the shower, push them down onto their knees to pee in their mouths, or stand them up for a quick shower fuck, usually anal.

Susan also immensely enjoyed our servants, but it was usually more gentle, usually in bed, usually planned in advance.

One morning, at the breakfast table, Kaitlyn surprised me with a burst of creativity.

"You know, Daddy, you haven't fucked me in two days.  Do you think you could fuck me, right here and now?"

I chuckled.  "Maybe, sweetheart.  Are you horny?"

"Yes, I am!"  She got up from the table, unsnapped her skirt, and pushed down her panties.  "See?  This is my little pussy."  She slurped twon of her fingers, and reached down to push them into herself.  "It need Daddy-cock, on the regular."

"What about last night?" asked Kathy from across the table.  "When our master was fucking me, and you came and sat on my face?  Your little pussy had no trouble juicing up and coming on my mouth."

"Yes, Mommy, and thanks for that.  I always love how good it is to commit incest with you, how hard I come.  But, it's not Daddy-cock."

"What about three days ago, when I surprised you walking down the hallway?" I said.  "You didn't expect me to strip you naked and push you up against the wall, ramming my lubed cock up your ass."

"That's true, Daddy, but that's my ass, not my pussy.  I'm so horny, I'd fuck anything, but it's you I want.  See?"  She showed us her fingers.  "I'm so wet!"

"Well, see here."  I stood up, and dropped my pants.  "See my cock?  It's half-hard.  If you want to get fucked, you're going to have to do or say something to get me fully hard.

"Oh, can I help?" asked Kathy, smiling as she slipped into full slut mode.  Her hands were already undoing her blouse.  "How about letting me fuck my daughter in her tight, wet, horny little pussy?  I'll take a turn first."

"Yes, Daddy," encouraged Kaitlyn.  "Mommy can fuck me first, and you can put your cock in my mouth while she fucks me."

"Sure, sweetheart."  Kathy shuffled out of the room.  I went over to Kaitlyn, and kissed her hotly while she continued to finger herself.

"Daddy, can I use the pregnancy fantasy?" asked Kaitlyn.

"Sure, sweetheart."  It was one of many scenarios they had come up with, to give a flavor to their dirty talk.

Kathy came back into the room, stark naked except for her strap-on harness with a medium-sized dildo in it.  She came over, kissed each of deeply, then bent Kaitlyn over to breakfast table, lined up behind her, and pushed her cock in.

"I'm always happy to fuck my daughter when she needs it," said Kathy.

"Oh, nice!" gasped Katlyn.  "God, Mom, you're filling me up so nicely.  But only Daddy can get me pregnant."

I was getting hard, so I put myself in Kaitlyn's mouth to suck.

"Oh, pregnant!" said Kathy with a smile, recognizing the fantasy. "Would you like that, master?  Would you like to breed my daughter? Would you like to ejaculate your sperm right into her little teenaged womb, and make a baby in her?"

"I don't know," I said, chuckling and playing reluctant.  "Then she'd get a big swollen belly."

"Yes, think about how fun and kinky that will be, to fuck her when she's pregnant!" encouraged Kathy.  "Her tits will start to make milk, and you can drink it while you fuck her, and her ass will be even tighter if you fuck her there."

"This sounds like something you want."

"I do!  I want to have lesbian incest sex with my pregnant daughter.  I want to drink milk from her tits!  And while you're at it, you could get me pregnant again too!  I'd have another boy or girl, and when they get old enough, there's even more kinds of incest I could commit!"

I pulled out of Kaitlyn's mouth, fully hard, and moved around behind her.  Kathy pulled out, I slid my cock into Kaitlyn very, very wet pussy.

"Oh, yes Daddy!"  cried Kaitlyn as I started to fuck her.  "Your cock feels so good.  Come inside me, get me pregnant, and make Mommy pregnant too!  Give me a baby, and another brother or sister!"

"If it's a boy, as soon as he turns 14, I want to suck him off every day, before school!" enthused Kaitlyn.  "Or give me a girl, and she can suck my cunt every day, and I'll bring her to you, Daddy, for you to have every kind of sex with."

"I think you should get us pregnant, again and again," said Kathy, laying one hand on my hips as I thrust rhythmically into Kaitlyn.  "That way, there will always be lots of teenaged pussy for you to incestuously fuck, and lots of teenage cock to keep my daughter-slut and me well-fucked, our boys draining their cocks in our mouth, our pussies, and especially, I want to get slammed all the time with lots of incestuous anal sex."

That did it.  I held myself deep in Kaitlyn, the head of my cock right against her cervix, and blasted a large load of cum into her.

"Whew!" said Kathy, bending down to pull me out and suck me clean.  "That's quite a fantasy, isn't it."

"I loved it," said Kaitlyn.  "But as good as the fuck was, I still need to get off."

"Don't worry," I said.  "Your mother is right here to eat your creampie and suck your clit, isn't she?"

"Of course," purred Kathy, kneeling down to get busy.

"Oh, Daddy," said Kaitlyn, moaning.  "It's quite a fantasy, but I'd really like you to do it someday, you know.  I really would have a daughter and have sex with her, just like Mom and me."

I chuckled.  "Maybe when you're older."
