                       A Relative Interest
                         An Erotic Story

     I've been reading these stories for a while; and finally 
decided to share an experience I had with my sister-in-law.  I 
should say, the first such experience; because it's a 
relationship that's still going on.
     My wife's sister, Katie, got married to Rob about 5 years 
ago and she's now 25 years old.  My wife Carrie (their parents 
liked rhyming names) and I were married 3 1/2 years ago.  She's 
27 and I'm 28.  We haven't had any children yet; but Katie has a 
4 year old daughter, Megan, and a 1 year old son, Tyler.
     So now that you have the family history, here's what 
happened:  Rob works as a computer systems manager for a big 
corporation that has offices across the US.  Sometimes he gets 
called to offices in other states to help with computer 
installations or upgrades.  His boss was nice to him and had not 
sent him away since his wife had their second child.  But 
compassion can only last so long and now he was across the 
country for a week.  Carrie invited Katie to stay with us during 
that time so she would have help with the kids.
     Katie came to our house Sunday after dropping Rob off at the 
airport.  I carried in the pile of luggage (babies and little 
kids require an awful lot of it) and got them settled in our 
guest room with a portable crib in the corner.  Katie and Megan 
were going to sleep in the king-size bed.
     Megan was soon settled in front of the TV with a kid's 
video.  Tyler was fussing; so Katie pulled up her T-shirt, 
unsnapped her nursing bra, and plugged him into a nipple.  She 
had done this many times in front of Carrie and me; so it was no 
big deal.  We sat in the living room talking while Tyler drank 
his fill.  I was somewhat excited by Katie's firm breasts and 
incredibly long nipples.  A nursing woman's nipples are so long 
and fat!
     At bedtime Carrie fell asleep quickly while I was reading.  
I heard Katie and Megan giggling in the guest room so I slipped 
on a pair of boxers and went to see what they were up to.  Their 
bedroom door was open.
     "What's up guys?" I asked, as I stepped in to the doorway.
     "Just girl stuff," Katie replied and Megan started giggling 
again.
     But the reason for their laughter was no longer of interest 
to me as I took in the scene before me.  Katie was lying on her 
side, nude, with Tyler snuggled up to her chest nursing.  Megan 
was also nude and was sitting on her mom's hip like it was a 
saddle.  She was moving her tiny pelvis back and forth mimicking 
the motions of a galloping horse, or .... No, a little girl 
wouldn't know about that, I thought.
     I felt my cock starting to expand so I thought I'd better 
make a swift retreat.  "OK, good night," I said and backed toward 
the door.
     "Wait!" Katie said.  "We're not sleepy, yet.  Stay and talk 
a while."




                                1


     I quickly slid to the floor with my back against the 
dresser; and sat with my knees raised to my chest to hide my 
erection.  We talked about Rob's job and Katie's plans to go back 
to her job as assistant coach of the girl's volleyball and track 
teams at the local high school.  After a while, Tyler dropped off 
to sleep.
     "Let me get up and put him in his crib," Katie said to 
Megan.
     Megan slid off her mom's hip and sprawled on the bed; 
leaning back on her elbows, legs spread wide, giving me a great 
view of her smooth, puffy mound, glowing pink from its friction 
on her mother's hip, with its tightly closed slit.
     I had never thought of little girls as sexual objects 
before, but now I could feel the pre-cum start to ooze out of my 
cock.  I glanced over at Carrie as she was leaning over the crib 
putting Tyler down.  From this angle her firm, athletic body was 
a duplicate of Carrie's.  She had worked hard to regain her 
athletic figure after each birth.  When she had gotten up from 
the bed I noticed that she shaved her pussy to leave just a 
small, trim strip of hair above her slit.  As she bent over, 
there was no hair hiding the glistening, pink slit.  Glistening? 
It was moist?
     Katie walked back to the bed and sat down, entirely at ease 
with me seeing her delectable body; actually quite like Carrie's 
except for her swollen breasts.
     Megan sat up and asked, "Mommy, can I have some, too?" 
putting her little hand under one of Katie's breasts and pulling 
it toward herself.
     "Ty didn't leave much, but you can try," Katie said, putting 
her arm around Megan and pulling her onto her lap.
     As Megan took the nipple into her mouth and started sucking, 
Katie looked at me and smiled.  "Megan and I enjoy snuggling like 
this.  I think there's a little left in this side," she said, 
cupping her other breast with her free hand.  "Rob likes to 
finish what Ty doesn't get; but since he's not here, maybe you'd 
like to try."
     I crawled on my hands and knees like a baby to the side of 
the bed where Katie was sitting.  As I leaned forward to take the 
long, engorged nursing nipple in my mouth, the bare skin of my 
chest and stomach touched both Megan and Katie's warm, soft skin.
     Katie continued to hold her breast up so I could suck.  
Megan put one arm around my neck as her other hand continued to 
support the breast she was nursing on.  I wrapped my arms around 
both mother and daughter as I knelt, sucking gently on the nipple 
that was at least three times the size of Carrie's.  I felt a 
warm, thin liquid trickle into my mouth.  My cock was pressing 
against Katie's shin, and my hips automatically began rubbing it 
up and down.  My sucking became more urgent and I started 
massaging the massive nipple with my tongue.
     "Mmmm," Katie sighed.  "That feels good."
     Megan's legs had been pressing against my stomach as I 
rubbed my cock against Katie's leg.  Now I felt her body slide 
off Katie's lap.  She ended up standing on the floor between 
Katie's legs; her soft body pressed against me.  My hip movements 
were quite obvious to her.


                                2


     "Mommy are you and Uncle Terry going to have sex?"
     "Why, honey?" Katie asked without a trace of surprise.
     "Cause that's what you and Daddy do after he drinks your 
milk."
     I pulled back from Katie's breast and looked into her eyes.  
The look of smoldering passion there reminded me again of how 
much she resembled Carrie.  Then I looked at Megan, and saw her 
mother in miniature.  Suddenly, I realized why mother and 
daughter were so open with their nudity.
     "Do you like watching Mommy and Daddy?"
     "Yeah, but I don't just watch," the little girl replied.
     "Now Megan, let's not tell Uncle Terry all our secrets yet," 
Katie said with a mischievous smile.  "Let's surprise him."
     "OK" Megan said, and held a hand to her mouth to hide her 
giggles.
     I had a suspicion about what they had been giggling over 
before I came into the bedroom.
     My cock had deflated while this exchange was going on.  
Katie pushed me back and stood up.  Her carefully trimmed pussy 
was at the right level for me to plant a kiss directly on the 
strip of hair.
     "That's a start," she said as she held my head in her hands 
and pulled it toward her.  She spread her legs and my tongue slid 
into the crack of her pussy.  She tilted her hips forward to give 
me a clear shot at it.  As I slid my tongue back and forth over 
the slit her pussy lips became swollen and her slit opened to 
give me access to her hole, which was dripping juices.
     I felt Megan's small, soft body press against my back and 
her face was beside my right arm, closely watching what I was 
doing to her mother.  Katie's hips had begun their familiar 
movements when she suddenly reached down and pulled me up by the 
arms.  We embraced and my cloth covered cock slid between her 
legs.
     "I think it's time to get rid of these," she said.  She 
knelt and pulled the boxers down to my ankles.  My 7 inch 
erection stood straight out.  "So that's what you've been 
hiding," she said.
     Megan giggled again; and sat on the edge of the bed, 
watching.
     Grasping the base of my cock, Katie licked the pre-cum off 
the end of it.  "Oh, I love that taste," she said, smiling up at 
me.
     "Let me taste," Megan said, sliding off the bed.  Katie 
milked my cock so another bead of pre-cum appeared at the tip.  
Megan's small mouth enveloped the whole tip and I felt her tiny 
tongue licking it.  I almost shot off right then.
     Katie recognized from my groans that I couldn't take much of 
that and said, "That's enough for now, honey.  Your uncle and I 
want to have some more fun first."
     Realizing that a blowjob would push me over the edge in no 
time, Katie stood again and pulled me onto the bed with her.  We 
embraced and kissed for a while to give my cock a chance to cool 
off.




                                3


     With my eyes closed I swore I was making love to my wife.  
Megan finally got bored of watching and jumped on top of us, and 
we became a squirming, giggling pile.  I ran my hands over 
Megan's smooth, soft body; finding various places to tickle.  
Then my hand landed on her smooth pubic mound.  Rather than 
remove it, I applied pressure and was rewarded by the child 
spreading her legs so that my fingers slid along her slit, then 
clamping her legs shut to press my hand against her young pussy.
     Katie saw what her daughter had done and smiled.  "Well, 
it's about time you gave her some real attention."  She leaned 
over me and gave me a long, passionate, open-mouth kiss.
     Meanwhile, the middle finger of the hand clamped between 
Megan's legs was beginning to worm its way into the girl's slit.
     Megan was squirming.  "Rub me there, Uncle Terry" she said.  
"I like it."
     I realized that her immature body wasn't going to produce 
the lubricant I needed to rub her without making her sore.  I 
broke from her mother's kiss and said to Megan, "I've got a 
surprise for you, now."  Lifting her tiny body I pulled her 
bottom toward my head.
     She giggled and released her grip on my hand; spreading her 
legs wide, as if she knew what was coming.  I laid her on my 
chest, her pussy against my mouth and her legs now squeezing my 
head.  My tongue slid along the smooth (no hair stubble!), 
rubbery skin of her pussy and opened her slit.  With the 
sensitive tip of my tongue I felt the tiny bump that would become 
her clitoris, and the tiny hole that would someday admit a (Her 
father's? Her brother's? My?) cock.  I suspected that day would 
not be too far in the future, especially if it would be her 
brother's tiny erection that got the first shot.
     My hands lightly caressed the smooth, baby soft skin of her 
back, butt and legs as I licked her.
     "Mmmmm ... I like that Uncle Terry," the little girl said 
with a sigh.  "Mommy, can you suck Uncle Terry so I can watch?" 
she asked.
     "OK, but not too long," Katie replied.  "You want to watch 
us fucking, don't you?"
     "Oh, yes," the 4 year old said.
     I felt Katie once again grasp the base of my cock to steady 
it; but this time, instead of licking the tip, I felt her lips 
encircle my cock and then slowly travel down its length until her 
nose hit my pubic hair.  I couldn't believe it.  There the 
comparison with her sister ended.  Carrie could never deep throat 
my 7 inches; but Katie took it all without gagging.
     "Oh yes!" I moaned.
     She slowly pulled her head back; pressing the underside of 
my cock with her tongue as she did so.  When she got to the 
sensitive spot under the head her tongue swirled and danced 
across it, causing my hips to bounce.
     "Wheee! Uncle Terry's giving me a ride," Megan laughed, as 
her body bounced in rhythm with my hips.  It was a little 
disappointing to know that she was too young to have an orgasm; 
but my tongue slid back and forth between her immature clit and 
puckered little hole, just as if I was driving her toward a 
climax.


                                4


     She was moving her hips in a very mature way; and she later 
told me that she got real good feelings from being licked or 
rubbed, and she was hoping for the day when she would have an 
orgasm like her mommy did.  Sometimes she would straddle her 
daddy's cock and rub her pussy along the length of it.  She 
showed me how another night ... but that's another story.
     Katie pulled her head back, straddled my hips with her legs 
and I felt her put the tip of my cock at the entrance of her 
pussy.  Looking over Megan's tiny ass I met Katie's eyes.  She 
smiled.
     Megan stopped squirming on my tongue and I sensed she was 
absorbed in the action taking place inches from her face.  Katie 
began moving her hips back and forth, just like her daughter had 
been doing when I first walked into the room.  My cock slowly 
entered her.  Her eyes never left mine, but her lids slowly 
lowered and her face took on a more passionate look as she felt 
me enter her pussy.  Her saliva on my cock, and the generous 
lubrication that her own excitement had produced, let her sink 
fully onto my rod without a hitch.  She putting her hands back on 
the bed beside my knees, she leaned back to expose the joining of 
our bodies to Megan's eyes.
     "Oh wow!" was all the little girl said.  She scooted her 
body forward, pulling her succulent, little pussy from my mouth.
     I raised my head and saw her face pressed against her 
mother's groin.  Her lower jaw was pressing down against mine.  
Then I felt her little tongue lick the small portion of my cock 
that was still outside her mother's pussy.  Judging from Katie's 
sigh and the way her inner muscles grasped my cock, the little 
girl's tongue must have continued up across her mother's clit.
     "Yesss, Megan.  Do that for Mommy."  I felt Megan's head 
raise up a bit and she said "And for Uncle Terry."  Katie smiled 
at me.  "And for Uncle Terry," she repeated.  Her eyes no longer 
focused on mine.  It was as if she was looking inward as the 
sensations built.  Her hips gently moved back and forth to 
massage the inside of her pussy with my cock, but never so hard 
as to dislodge Megan.  I felt the pressure growing in my cock as 
my body demanded release.
     Katie had her eyes closed and was moaning softly with each 
breath.  Then she started saying, "Oh yes ...  oh yes ...  lick 
it baby ... I'm going to cum ... oh yessss ... AAAHHH!!" Her hips 
bucked and this time Megan was pushed away.  Katie pounded her 
pussy down on my cock, her hips and legs jerked, and I felt her 
well-developed muscles squeezing me inside her.
     That did it.  I exploded with a loud "YESSS!! ... Oh ... 
OH  ... FUCK!!!" My cum spouted into Katie's pussy ... so much of 
it that I soon felt it running out and over my balls, cooling 
them.  I felt Megan wrap her arms and legs around my body to "go 
along for the ride" as I bucked upwards; shooting more cum into 
my sister-in-law.
     Katie's bouncing slowed, then I felt the muscles of her 
buttocks and legs flex and knew from my love making with Carrie 
that it wasn't over yet.





                                5


     "Oh yesss!" she exclaimed again as another orgasm shook her 
body and she ground her pussy onto my cock.  This happened a 
couple more times, each time with lessening fury, until she just 
lay on top of me, her hips twitching, her thighs alternately 
squeezing my hips and then relaxing, the muscles inside her pussy 
squeezing my cock.
     Megan had slid off me and was now lying on top of her 
mother's back, feeling the last spasms of her mother's passionate 
orgasm.
     "Damn, Carrie was right ... you ARE good."  Katie softly 
said in my ear.
     "What??" was all I could say in my surprise.
     "Carrie and I don't hold anything back from each other.  I'm 
surprised you haven't learned that by now.  In fact, I'm 
surprised it took 3 1/2 years after you joined our family to get 
around to fucking me."
     "You anticipated this?" I asked.
     "Sure.  After all, Rob's been getting a quickie or a blowjob 
from Carrie about every other month since we've been married."
     I didn't know how to take that.
     In the silence, Megan said, "I'm ready to sleep, Mommy."  
She slid off Katie's back, crawled across the huge bed, under the 
covers on the other side and promptly dropped off to sleep.
     "I've been flirting with you for years," Katie said, raising 
up to look into my eyes.  "Rob caught on to Carrie's desires 
within a few months of marrying me."
     "I thought you were just playing around," I replied.
     "Now you know different," she said with a smile, and kissed 
me with an open mouth, probing with her tongue.
     I felt my cock stir ... amazing, after the ball-busting 
orgasm I just had.  When she broke the kiss I asked, "Was this 
night planned?"
     "Yep.  Rob didn't have to take that trip .... His boss gave 
him a choice.  But we figured it was time you were initiated into 
our family sex play."
     As she said "family" I glanced over at Katie.  "She's great, 
isn't she?  Carrie and I decided that our children wouldn't be as 
sexually oblivious as we were, going into our teen years.  We 
started masturbating when I was around 13.  Carries discovered 
how to make herself climax first, and showed me how.  We watched 
each other do it for about six months, then one day I suddenly 
seemed to notice how sexy her little breasts looked even though 
we'd seen each other nude every day of our lives.  She was older, 
and a little more developed than I was.  I guess she just looked 
sexier because we were sitting at opposite ends of our living 
room sofa while our parents were away one evening, we were nude 
had our legs spread and were watching each other rubbing our 
clits.  Anyway, I leaned over and stroked her breast and nipple.  
She shuddered and said it felt great.  We started stroking each 
other's body all over and it was never the same, dull 
masturbation scene again.  And as we got older we decided we 
wouldn't deprive our children of sexual pleasure as long as we 
had been deprived of it."




                                6


     "We make love whenever the mood strikes, whether Megan is 
around or not.  At first, it was no more interesting to her than 
watching us brush our teeth, but in the past six months or so she 
has enjoyed participating like she did tonight."
     "So do you and Carrie still do it now that you're married?" 
I asked.
     She said, "If you had fallen asleep first, Carrie would have 
been in here with Megan and me tonight."
     The image of the sister's and Megan pleasuring each other 
popped into my mind, and went straight to my cock which now rose 
it its full length.
     "Now, let's have a nightcap and then you need to get to 
bed," Katie said.  She rolled off me and got on her knees.  
"Carrie said you're especially fond of this position.  Something 
about watching your cock slide in and out of her pussy really 
turns you on."
     I got into position behind her and placed my cock at the 
opening to her pussy.  I slowly pressed it forward and watched it 
disappear inside her.
     Katie dropped her head to the bed and tilted her hips up so 
I got a good view of her pussy lips being pulled inside with my 
cock, then being stretched out and I slid my rod almost all the 
way out of her.  I increased the pace of my stroke.  I reached 
forward to grasp her swollen breasts and those magnificent 
nipples that had started this all.
     "Don't," she warned.  "They're filling up and it would be 
like milking a cow if you played with them now.  Except there's 
no bucket under them," she laughed.  "This is just for you.  You 
gave me a great orgasm before an I don't need another one now."
     I didn't give her an argument.  I just grasped her hips and 
went to town, plunging in and out of her pussy with abandon.  My 
hips driving my cock into her, and her responding, adjusting to 
rhythm.  My breathing grew ragged and I started moaning.  
Then ... "Oh shit ... here it comes ... OH Yessss  ... OH FUCK!!" 
I slammed my hips against her firm butt and poured another load 
of cum into her.  The excitement of the whole evening seemed to 
open up reservoirs of cum and it was soon dripping from her 
pussy.  After my cock stopped twitching, I pulled out and grabbed 
a handful of tissues from the box on the nightstand to mop up the 
bed, her pussy and my cock.
     "Next time we fuck it will have to be earlier so Megan 
doesn't fall asleep on us."  Katie said as we cleaned up.
     "Why?"
     "Because she likes to lick us clean."
     My cock almost twitched at the thought, but it was dead 
tired by now.  "Do you think Carrie might want to join us, too?"
     "I'd say she's looking forward to it."  Katie replied.  We 
kissed goodnight, and I silently walked back into the master 
bedroom.  I slipped into bed and settled down.

     Carrie turned over and reached out a hand to touch me.  
"Mmmm, back?" she said sleepily.
     "Yes," I whispered.
     "Was it good?" she murmured.
     I slid across the bed and embraced her.
     "Almost as good as you," I whispered in her ear.
     "Mmmm ...,"  she murmured; kissed me lightly on the cheek, 
then drifted back to sleep in my arms.  

     What happened the rest of the week?
     That's another story.
