In most ways I’m a normal 15-year-old boy, sandy colored hair and an average physique. I like cars and football and girls. I would jack off to a pretty blonde girl in my history class. Last year a neighbor girl let me kiss her and touch her tits, so I was eager for more.

In some ways I wasn’t quite normal. I’m a little nerdy, with my nose in a book more often than not. I’m interested in technology for its own sake, and I read Popular Science and Popular Mechanics.

I have an older sister Kristen (I call her Sissy), she’s 17, a slim figure with small breasts, dark hair and big brown eyes.

One rainy Saturday I was sitting on the couch in the basement reading a book. I don’t remember which one, a sci-fi book with good space battle action. Sissy came up to me and asked, “How do I look?”

I assumed she wanted an honest, objective opinion. She asked my opinion of her appearance occasionally, and I didn’t mind obliging. My mind was on the book though, so I got up and walked around her to make a quick assessment. She was wearing jeans, a gauzy light green shirt tied at the waist, sneakers.


“Pants look nice.

“That looks trampy,” pointing to the knot of the shirt.

She had on a light colored bra that didn’t work with the shirt. I reached  to feel the bra. I heard a sharp intake of her breath as my fingers touched her chest. I just assumed it was because they were cold from holding a book for two hours straight.

“Bra doesn’t work for me,” It was padded. I looked at her make-up. “Too much eye shadow.

“Don’t like the shoes, either.”

I took her hand and led her off to her room. I hardly ever go into her room, but I did know where she kept her underwear. I rummaged around until I found a bra that matched her jeans. It was also of a light, sheer fabric, which with the shirt would hide her boobs, but reveal when her nipples were hard.

“Here, put this one on,” I handed it to her as I left. “And find some less flashy shoes.”

I wanted to get back to the book. I didn’t realize until I was on the stairs that her shirt was already unbuttoned and off her shoulders. I dismissed it as her hurry.

She came back to me with the new bra and the makeup more subdued. And her shirt was properly tucked in. I smiled up at her, “That looks nice.”

She smiled.

My nose went back to my book.

“Um. David? Would you like to come with me?”

“No thanks,” I said without looking up. Why the hell would I want to spend time with my sister and her goofy friends, listening to them chatter about stupid crap? Especially when I could be right here reading about the space pirates using some cool gizmo called a gravitic lance that tore the shit out of their prey…

She left and I forgot about her.

A few days later I was at the kitchen table doing homework.

“How do I look?”

Sissy was wearing a red miniskirt with a white blouse, red patent leather shoes. I walked around her. I lifted up her skirt. Lacy black panties. “Um. Black doesn’t work here. If you don’t have white use dark red or pink.”

I looked at her face. “Too much eye shadow. And you went a little overboard with the blush. Lip gloss looks nice, though.”

She went off to fix herself.

Now at this point you may be wondering how a relatively normal, if a little nerdy, guy knows about fashion and make-up. I don’t. I don’t have a goddamn clue. I don’t watch the makeover shows or look at magazines. All I know is what I like and what’s too much, and it’s pretty easy to tell what’s too much.


I looked up.

“Will you come with me? Please?” she looked at me hopefully.

“I can’t Sissy. I have to finish this,” I said, gesturing at my homework.

She left.

Next Sunday I was back on the couch again, book in hand.

Sissy called downstairs, “Could you help me?”

“What?!” I yelled up at her.

“I need you to help me decide which dress to wear.”


I was reading a passage involving rishathra, and I had a boner.

I went into her room and she was covering herself with one dress and holding another beside it. I also noticed in the mirror behind her that she was wearing only a bra and panties. Now, I’d seen her in her underwear before of course, but never with such non-chalance.

I ignored it and went into my ‘evaluation mode’. I looked at her and the dresses.

“I like the blue one.” As I said, I don’t have any idea about fashion. It had a snugged-in waist that I thought would show off her nice little figure and that’s why I picked it.

I looked at her closely.

“And what is it with you and eye shadow? You always seem to cake it on.”

She had a hurt look on her face. “I thought you guys liked the exotic look.” she said.

“Exotic sure, but not trampy. Be subtle.”

“Okay,” she looked down.

I left her room, closing the door behind me. On the way out, something caught my eye, but I didn’t pay much attention. I wanted to get back to my rishathra. A few minutes later (actually it was probably more like 20) Sissy came downstairs. I looked up at her.

She really did look nice.

“Wow, Sissy, you look good.”

She blushed visibly, “Thank you.”

The dress did set off her figure, without being tight, and she had matching shoes. She had put her hair up, lending an air of elegance.

“I suppose you don’t want to come with me again,” she asked.

“Actually I would, but I’m kind of preoccupied right now.”

“Okay. Bye!” she said, as she bent to kiss me on the cheek. Then she left.

She hadn’t done that in a while, but I just figured she was excited about her date or whatever. I didn’t know where she was going—she never said.

Then I remembered what caught my eye. She was gone now, so I went into her room to look.

The book. On her nightstand. I remembered it was there last week when I got her whatever. Sissy’s not the reader I am, but it certainly wouldn’t take her a week to read a book.

I picked it up.

Flowers in the Attic. Whatever. What’s so special about it? I decided to find out. So I read it. I didn’t want her to know I was reading it, so I had to put it back exactly where I found it. I sat in the hallway so I could quickly return it when someone came home.

It took me a couple days, barely an hour at a time sometimes, before someone came home. I didn’t see what she could like about it. That woman was really creepy. Kind of described Eric’s aunt. At least from what he said. Eric was in history class. (The same one as Lily, the blond with such nice tits.)

As I got deeper into the book I noticed where things were headed.

Oh, boy.

Oh, fuck.

The brother and the sister.

And their, uh, relationship.

Then I got to the part where her bookmark was, near the end.

A brief, forbidden-lust passage without much detail, leaving a lot to the imagination.

And Sissy was… Oh, fuck. It was on her nightstand. She wasn’t just curious about it… She was… She was jacking off to it. And that meant…

Oh, man.

I carefully put the book back, making sure everything was exactly where she left it.

I had to get out of the house.

I got a coat and grabbed my science notebook. I walked around for a couple hours, my mind in a daze, not wanting to think about what I discovered. Eventually I went to Jackie’s house. Jackie is my lab partner in science class. She’s the model female nerd. Fat, pimply, thick glasses and a funny smell. She’s also the smartest one in the class, so I’m willing to put up with it.

She was home, of course, and her mother got us a snack as we sat at the kitchen table reviewing our project due Friday. Figuring out what to do is my part. I literally do it in my sleep. I wake up with an idea, and then write it all down. All we have to do is spend a few hours finishing it.

I showed her my plan. She liked it.

“That’s what I like about you Dave, flashes of brilliance.”

We started work on it until I thought at least one of my parents would be home and then I left.

At dinner I was distracted to say the least. I couldn’t look at Sissy. Dad seems oblivious as usual, but Mom picked up on it.

“What’s the matter, David. You look preoccupied.”

“Nothing. Just thinking about my science project. It’s due Friday.”

“Oh. Well I’m sure you’ll come up with something good.”

I’m sure Sissy noticed me too, and I don’t think she was buying the line about the science project, no matter how plausible it was.

That night I was bothered by weird dreams and didn’t sleep well.

The next day in school I was still in a daze and I couldn’t really function. I managed to answer questions correctly, but a couple people noticed my odd behavior and I told them the half-truth of not sleeping well. I couldn’t even say ‘Hi’ to Lily in history class, let alone try to start a conversation.

After fumbling my way through the day I stayed away from home until I was sure Mom was home, and kept myself busy with homework, surfing the net and reading until bedtime. It seemed to me Sissy was avoiding me, which I thought was just fine with me.

As I lay in bed I realized the shock had finally worn off and I could think a little clearly.

Okay. Sissy is interested in incest. Very interested.

She wants me. She wants me. My sister. Wants a relationship. With me. All the little things fell into place. Asking me about her appearance. Taking her shirt off when I was still in her room. Standing there in her underwear. And doing all of this, I realized, when we had the house to ourselves.

I slept much better that night now that I knew what was going on. I may be good at technology, but I’m as clueless as the next male teenager when it comes to interpersonal relationships.

A couple days went by and I was able to act normally, even around Sissy.

Then Thursday night I woke up to a voice saying Why not?

I was so sure I heard it for real I replied “What?” out loud.

Why the hell not?

“Why not what?” I asked.

Dumbshit. Sissy.

This was the same voice that gave me the science projects, only is was usually a gestalt, coming to me all at once. I was half asleep and half dreaming.

I lay there semi-conscious, but the voice spoke no more.

Why not Sissy? it said.

Oh, fuck.


A relationship with Sissy.

A relationship with Sissy.

 Hm. Why not. Hm.

Sissy loves me. Truly and deeply. Devoted love. And now she is in love with me. Wants me. Desires me. Not some coy teasing like the neighbor girl. Not half-ass teen flirting like Lily.

And I love her too. I have loved her all my life. Why can’t I return her love? Because I grew up with the cultural and biological notion that it is evil/sinful/bad/perverted/taboo? I read hella books, and I may be young, but my mind is certainly open.

Here is a reasonably attractive girl that loves me and wants me. And there aren’t any others. And there’s no one I’m really interested in except Lily, and that’s just physical. I can have a real relationship with a girl that loves me, or I can keep jacking off to books and a cute girl I flirt with.


Why the hell not?


I went back to sleep.

I woke up trying to remember a book I read with a nice, juicy subplot of incestuous love. I could only remember it was part of the Chung Kuo series, but not which. And I wasn’t about to read through thousands of pages to figure out which.


I had wanted to show it to her, to let her know I was open to the idea.

Friday morning and I felt good. The science project was already finished. We got permission to turn it in a day early. I smiled at Sissy and said ‘Hi’ to her as I passed her in the hall. She blushed. God, she has it bad.

Had a good time at school. Really flirted with Lily. Maybe because I had someone else on my mind now, and Lily’s responses didn’t matter so much.

That night at dinner Dad announced we would have the house to ourselves this weekend as they were going to the casino/resort with another couple from Dad’s work. Perfect.

I would have to play this right.

I would have to be cool and focused, like Honor Harrington plotting against her enemies… not like Miles Vorkosigan, blustering in to save the day.

Sissy would probably try yet another ploy, but I would have a couple of my own in case hers didn’t go well.

I couldn’t be obvious, though. If I was too forward she might bolt.

I went about my usual Saturday. Homework, a few hours hanging out with Eric, and to my book. Classic Trek. The good ship Enterprise was in trouble and Kirk had his nuts in a vice. Again. I realized that I hadn’t seen Sissy since breakfast. Maybe she was holed up in her room.

Well, let’s try the Shower Plan then.

I took a shower. With the bathroom door wide open.

What seemed like half an hour later I was about to give up when I heard her come in. I could see her blurry form through the shower doors and I waited until she was seated on the toilet.

“Hi, Sissy,” I said. Not loud, but loud enough to be heard over the shower.

‘OH! I didn’t know you were in here! I’m sorry!” Yeah, right.

I opened the door and stuck my head out. Even wearing earbuds for plausible deniability of not hearing the shower.

“It’s okay. I didn’t know you were home.” I can boldly lie, too.

I withdrew my head so she could wipe and pull up her pants.

I saw her approach the door.

Phase 1. Make it easy for her.

I opened the door and stuck my head out again.

“Could I maybe—”

“Would you care to—”

We spoke at the same time.

“Go ahead,” I invited.

“No, you,” she replied.

“I was going to ask if you would care to join me. You haven’t taken a shower with me in five years.”

She beamed.

“I’d like that,” she managed to say evenly.

So far so good, Captain. She’s taken the bait. Now for the kill.

Easy. Let’s not rush this. Cover all the bases in case there’s something we haven’t though of…

Sissy stripped her clothes off and came in. I changed places with her to let her stand under the hot shower.

Seeing my older sister totally naked for the first time in a few years was quite a treat. She really was quite nice looking, if a little on the skinny side. As I watched her I had to remain detached enough to keep from getting a hard on. First thing I did in the shower was to jack myself off, but being 15 meant a boner was always a ready possibility.

As she wet herself I took a washcloth and soaped it up. I exchanged places with her and began to wash her, she facing away from me. I started up at her neck and shoulders, down her arms, washing with one hand and rubbing the soapy lather with the other. Then down her back. Then up her sides.


“Sorry.” I had forgotten she was ticklish.

Okay. Phase 2.

With the washcloth in one hand I reached around and rubbed it right across her tits, then up and back across her collar bone, then down and across her belly. Then I rubbed my other hand right across her soapy tits. I felt her nipples spring up at my touch, and I felt her back into me. Nice.

I just kept rubbing across her tits with my bare hand as my other hand washed downward with the washcloth. I washed her thighs. Then she spread her legs, an obvious invitation. I washed her crotch and in between her legs. Then as I washed back across her hip my other hand moved down to rub and cup her crotch. I swear I felt it pulsing. By then she was leaning against me.

I held onto her hip with that hand to steady myself as I squatted down to wash her ass and her legs. Her legs were still spread, so I washed her ass and crotch and inner thighs, then washed each leg. As I stood up I cupped her ass low, being sure to reach in between her legs with my middle finger. I felt her twitch and shudder as I did.

I just wrapped my arms around her and held her then.

That’s not part of the plan.

Playing a hunch.

She leaned back into me again and I heard her sigh. I couldn’t see her smile, but I knew she was beaming.

“This feels so good,”she said.

“Sissy?” I asked, “Why did you stop taking showers with me?”

“Because girls at that age are very self-conscious.”

“Oh.” Plausible. She was 12 and still flat with a bald pussy, but that’s when hormones start flowing.

“And I made the mistake of telling my friends I still showered with my little brother and was teased mercilessly.”

I held her tighter.

I said right into her ear, “Well maybe you shouldn’t tell your friends some things about us…” and I nipped her earlobe.

She didn’t just twitch. She jerked.

Hm. Gotta remember that.

I should say.

I released my hold and handed her the washcloth.

“My turn,” I said as I exchanged places with her, making sure her tits rubbed across me as she did.

She lathered the washcloth and proceeded to wash me in return, much the same as I washed her. I was a little surprised that she was so tentative around my dick.

Be ready to fix that.

Aye, sir.

But slowly she washed it, first with the washcloth, and when it was good and lathery with her bare hand. She thoroughly washed it. Spent more time on it than I did on her crotch. Then she washed the rest of my body.

“You’re a lot bigger than the last time we took a shower together, Davey.”

“Yeah. You were a couple inches taller than me as I recall.”

“That’s not what I meant.”


Phase 3.

When she finished I turned to face her.

She was smiling, a little coyly, a little excitedly.

I slowly took her in my arms. I gently pulled her to me, feeling her tits and thighs touch me. I lifted her chin up and looked into her eyes. And I kissed her.

And not a little brother kiss, either.

Gently at first. Then opening my mouth more and sticking my tongue out, and feeling her mouth open in response. Our tongues gently touching and swirling around each other. I felt her grip on me tighten, and I responded. And so did my dick.

We held each other closely, our bodies pressed fully into each other. Then I remembered something.

“I just realized you called me Davey.”

“Did I?”

“You haven’t done that in about five years either.”

She smiled and giggled a little.

We kissed some more.

Then the water started to get cold and I turned it off.

Sissy’s nipples got harder as the air cooled. So did mine.

“Excuse me,” I said.

And I bent down to lick and suck her nipples.

Hunch again?

Aye, sir.

“MMMMmmmm… thank you,” she said.

We got out of the shower and toweled each other off. I made sure her tits and crotch were really dry. We just stood there a little while, facing each other and holding each other’s hands. My dick was sticking straight up then, demanding attention.

Phase 4.

I looked at the open door, her bedroom beyond. She slowly let go of my right hand and slowly led me by my left. I felt her tremble a little.

She led me to her bed, then laid down on it. On her back, in the time-tested missionary position, legs spread wide, knees in the air. I climbed on top of her, holding my full weight off her with my arms. I smiled at her and kissed her again.

“Sissy… I’ve never done this before. How do you want me to do it?”

“Any way you want to. I haven’t done it either, but I’m ready now.”

“But what about…”

“Don’t worry about that. I broke my hymen with my dildo. I didn’t want my first time with you to hurt. I only wanted it to feel good.”


It hit me. First time with you. Not just first time. How long had she been planning this anyway?

Then something else hit me…

I was in love with her.

When did that happen? I looked into her eyes. My sister. My lover.

“Sissy…” I whispered into hear ear. “My sister-love…” and I nipped her earlobe again, and got the same response.

I glanced at the lube on the nightstand. And at the book.

I shifted my weight and slowly inserted my throbbing cock into my beloved’s waiting cunt. Dripping wet. Wouldn’t be needing that lube. I slowly pushed until I was all the way in. Again I looked into her eyes. My first woman. Who has loved me all my life. Who desires me more than anyone else. As I desire her.


I began thrusting. Slowly at first, enjoying the feel of her tight cunt, a velvet fist around my cock. As I thrust she began moaning softly. With my free hand I explored her body, gently touching her. Not just her obviously inviting tits, but her neck, shoulder, collar bone… everywhere I could reach. I felt her gently squirming underneath me.

I felt her cunt tighten then, and got the urge to thrust harder and faster. It seemed she did too, bucking her hips in time with me. I wrapped my arms around her thighs and grabbed her wrists as she wrapped her legs around me. I rammed into her hard, grunting, as she made moans and squeals of pleasure.

“Oh shit! David! My love! I’m gonna…!”

I felt her whole body jerk as she came, and I kept pounding into my loving sister’s hot, wet cunt.

“OH! FUUUUUUCK!!” she screamed.

Her twitching cunt was enough to jolt my balls into action, and despite spooging the shower drain not an hour before I cut loose with wads of sticky goo, filling up her eager cunt with my love. Again and again I shot into her, “UUUUUUUNNNNNHH!!”

I kept squirting, knowing I was empty, but I wasn’t going to stop fucking the best sister in the whole world. I kept at it, pounding her cunt, feeling my balls slap against her ass.

“Ah-ah-ah…!” Sissy squealed. “Ah-ah-aaaaaHH!! OH yeaaaahhhh!”

A minor aftershock, compared to her earlier seismic event. But still, I enjoyed the feel of it.

I slowed my thrusting, and eventually stopped. My lover beamed at me.

“Thank you, David. Thank you so much. You’ve made me the happiest sister in the world. The happiest girl in the world. I love you,” she kissed me, then giggled. “I looooooooove you.”

I kissed her back.

“I love you Sissy. And you should know, that I’m in love with you too.”

“Good.” She smiled even more.

“I thought you might like knowing that.”

I slid off her and lay next to her, just looking at her. Then we turned on our sides and lay together spoon fashion. She took my hand and held it against her tits.

Well done, Commodore.

Thank you, Your Majesty.

Hm. I guess I missed the mission accomplished in there somewhere. Must’ve been preoccupied.



“I wanted to find a book to show you. To let you know it was okay. Then I thought, why didn’t you just give me the book?” I gestured toward the nightstand.

“Um… That wasn’t the only book…”

“Oh.” What?

She giggled.

I held her tightly.

I could say this is the end, but it’s really just the beginning…
