It was really, really late, like about three in the morning, when I heard the front door open. I was up in my bedroom and had been sleeping, but the sound of the door opening woke me up. I peered out my window and saw a car driving off, followed by the sound of my older sister calling out “Good night!” and giggling.

Ah. That meant Bre was home. She was 22 and spent just about every night she could out partying. Since it was summer, and our parents were gone for two weeks, this meant she did it basically every night.

I heard a thump from downstairs, and when I didn’t hear the sound of Bre’s feet on the stairs coming up to her room, I started to get a little worried. She’d passed out on the living room floor a few days ago. I wondered if she’d done that again. Last time I hadn’t found out until I’d woken up the next morning, but this time I was awake. I should go check on her, I concluded.

I got out of bed and crept out into the hallway. Clad only in my boxers and t-shirt I made my way down the stairs. I poked my head into the living room.

Yep, there was Bre. She’d fallen onto the couch and she looked completely passed out. I stood over her and sighed, not sure what to do. Finally I figured I should try to wake her up.

“Bre? Bre, it’s me, Cody. Wake up.”

She said nothing, didn’t even twitch, she was just there, sitting back, passed out. If it hadn’t been for the fact that she was breathing, I would have thought she was dead.

“Bre? Come on, Bre, wake up.” I reached down and shook her shoulders gently. She didn’t say anything, she just sat there propped against the couch back.

Now I was getting a little worried. I shook her by the shoulders again, and this time she moved slightly. I don’t think it was intentional, I think it was just gravity. She basically slid down the couch a little bit, leaving her with her butt right at the edge.

I sighed, and was just about to consider calling 911 when I happened to look down. The short skirt my sister had been wearing had ridden up and I could see that she wasn’t wearing any panties.

My breath caught in my throat. I looked down in the wan glow from the porch light shinning through the windows. Yes… no panties. Oh, wow. I was thirteen and I’d never even gotten close to getting laid. I’d certainly never seen a girl’s vagina in real life before. I figured that I could try to wake her up again, but meantime I wanted to get a closer look.

I got down on my knees between Bre’s legs and looked at what was splayed out there for me to see. I couldn’t see too much. There really wasn’t a lot of light. I could tell she didn’t have any pubic hair. She must’ve shaved it, I thought.

I sat back a little, my penis tenting out my boxers. I wanted to see more of Bre’s vagina, but I didn’t want to turn on a light. Getting an idea, I got up and walked into the kitchen were I rooted around until I found a flashlight. Then I went back into my previous position and shined the light onto my sister.

Now I could see better, thought I still couldn’t see a lot. There was a slit, and what looked like a series of folds. I had half expected just to see some hole where the guy’s penis when in, but that wasn’t the case.

Licking my lips, I looked up at my sister’s unconscious face. I put out the flashlight, stood up and shook her shoulders again, pretty hard this time, trying to see if she’d wake up.

Nothing.

I got back down on my knees and shined the light onto her vagina once more. Gently I placed a hand on each of my sister’s thighs and spread them a little wider, trying to get a better view of the treasure between her legs. It helped a little, though I was still kind of confused by what I saw.

My penis was throbbing and aching for release. I reached down and extracted it through the fly of my boxers, letting it pop up. I put my hand around it and gave it a couple strokes as I looked at my sister’s vagina, enjoying the view even if I didn’t really understand what I was seeing all that well.

Wondering how much I could get away with, I let go of my penis and placed my hand on my sister’s thigh. Slowly I moved it up until I was right near Bre’s vagina. Swallowing hard, I let a couple shaking fingers drift across her slit while I studied her face. No reaction.

Feeling a little bold, I let my entire hand come to rest over my sister’s vagina. I could feel heat and all sorts of interesting textures under my palm. It was really fascinating! I held my hand there for a bit and then moved it back down to my penis, giving it a couple strokes as I thought about what to do next.

Well, if she hadn’t woken up yet, she probably wouldn’t wake up if I poked my fingers around a little, I reasoned. Maybe I could find the place where the boy’s penis was supposed to go.

So I stuck out my index finger and traced it along the slit, from the little knob at the top down to the bottom. It was really cool! I ran my finger up and down a few times, and then started to notice an odd wetness appearing from somewhere. I had no idea where, or why. I started wondering if Bre had wet herself, but that didn’t seem right.

I moved in closer with the flashlight, seeing moisture glisten as I shined it at my sister’s vagina. I kept wondering what was causing it. I ran my finger along the slit again, and this time I noticed one spot that seemed extra wet. It was almost like an indentation. I poked my fingertip at it and felt it sink in slightly.

Understanding dawned. THIS was the place! It had to be. I pushed forward with my finger again, watching as it slid all the way into my sister’s vagina. I could feel the warm, moist flesh clinging to my finger as I held it inside her. Wow… this was cool. I moved my finger back and forth inside Bre’s vagina, totally blown away at how cool it felt around me.

Now I was trying to figure out what to do next. I was really wondering how much I could get away with, and how far I would go. I mean this was my sister, after all, so I couldn’t go all the way and fuck her. But maybe I could at least fool around a little more.

I thought I might try something. I stood up and dropped my boxers, my virgin penis popping up. I got back down between my sister’s legs and took my erection in my hand. I placed the tip at the top of her vagina and gently ran it down her slit, a shiver of pleasure shooting through my body.

As I ran my penis up and down on my sister’s vagina, I kept an eye on her face, looking out for any signs at all that she might be waking up. There was nothing. She just kept on sleeping, completely out of it.

I paused in my rubbings, letting the tip of my penis come to rest against the entrance to my sister’s vagina. Now I began to really think about sticking it in her. I mean, I couldn’t actually fuck her for real, but maybe if I were to stick all the way into her and then pull it right back out again, that wouldn’t really count as sex, but I would know what it felt like to be inside a girl.

Trying to stay calm, I figured I’d try a little experiment. I pushed my penis forward, feeling the tip slide into Bre’s vagina. It was very warm and wet and wonderful. With the entire tip stuck into her I looked up at her face, trying to spot any reaction. There was none.

Ok, I thought. I’d do it. I’d stick it all the way into her and then pull it right back out again. It wouldn’t officially count as sex, so it wouldn’t be wrong or anything like that. She’d never know I had it in her, but I’d know what it felt like.

I set down the flashlight and spread Bre’s legs as far as I could. Taking a deep breath, I reoriented my body and gave a little push with my hips. It was mind blowing. It almost felt like my sister’s 21- year-old vagina was sucking my 18-year-old virgin penis into her. There wasn’t any problem or any difficulty. I just slid smoothly and easily all the way right into her.

I closed my eyes and held myself motionless, my penis buried deep inside my older sister’s vagina. God, this was intense! I just stayed there, soaking inside her liquid warmth, knowing that I should pull out but not wanting to.

But I knew I had to. Very slowly, very reluctantly, I sat back, letting my penis slip out of Bre’s vagina. My mind was spinning as I looked at the wonderful place I’d just been inside. I couldn’t believe I’d actually done that! Technically, I realized, I wasn’t a virgin anymore. THAT was a cool thought!

I wanted to reach down and jerk off some more, but I also wanted to stick my penis back into my sister. I thought hard about it, trying to figure out what to do. Well, I guess that since I had already had it in her for a little bit, there probably wouldn’t be anything wrong with putting it back in her and fucking her a little, right? I mean, I couldn’t ever let her know that I’d done it, but there wouldn’t be anything really WRONG with it, would there?

I got back into position and placed my penis against my sister’s vagina again. I gave a little push and slid easily back into her. Wow, it was sweet. I sank my erection all the way into her warm embrace, and then pulled back a little. Then I slid in again, aware now that I was actually really fucking a girl!

I hadn’t really thought about what I’d do when I came. This was possibly not a wise omission on my part, because after only a couple more thrusts, I felt the most incredible, intense, magnificent orgasm of my young life begin, the feeling starting at the base of my penis and spreading out through my entire body as I pushed deep into my sister’s vagina, holding myself there as my sperm blasted into her.

As soon as I was done cumming, I pulled back, slipping out of Bre’s vagina and trying to get my breath back as the full impact of what I’d just done hit me. Oh, god. I’d fucked her and I’d came inside her! Shit, what if she got pregnant or something?

Shakily, I got to my feet and went into the kitchen. I helped myself to a glass of water and then walked, still naked, back into the living room where I looked at my sister’s unconscious body, trying to figure out what to do now.

It crossed my mind, as I stood there, my penis still somewhat hard, that I hadn’t seen my sister’s breasts yet. Given how much I’d already done, I might as well do that, too, and get a good look, I thought.

Bre was just wearing a fairly tight t-shirt. A quick exam showed that she didn’t seem to have a bra on under it. I got back between her legs and took hold of the bottom of her shirt. I lifted it up until her breasts popped out from under it, and then I sat back and took a good long look at them. They weren’t huge, but they sure weren’t small, and were very nice to look at. My somewhat hard penis instantly turned steel-hard once more.

Reaching up with a hand, I cupped one of my sister’s breasts, feeling the soft skin and the hard nipple under my palm. Damn, that was cool. I leaned forward and gave her nipple a little lick, blown away by how awesome this all was.

I wanted to feel my sister’s breasts against my bare chest, so I moved forward a little until I was pressed against them. This also had the nice benefit of bringing my penis back into contact with her vagina.

Naturally, I really wanted to fuck her again. I knew I shouldn’t. Hell, I shouldn’t be doing any of this. But since I’d already done it once, I guessed there wouldn’t be any harm in doing it again. She’d never know about it, after all.

Having made up my mind to fuck her again, I thought it might be cool if this time I was on top of her instead of just kneeling between her legs. It was a large couch, so I knew it wouldn’t be a big problem if I could get her into position. I also wanted her to be naked, so the first thing I did was pull her t-shirt off, and then removed her skirt completely.

That done, I gently placed my hands on Bre’s shoulders and pushed her over, moving her body until she was resting on her back. Then I spread her legs a little and got down on top of her, looking at my sister’s glorious, naked body.

I took one of her legs in my hand and held it up so that I could penetrate more easily. Then I lined up and guided my young penis back into my sister’s tight vagina. When I was completely inside her, I lowered my nude body on top of hers and simply held myself motionless for a bit.

This was really nice, I though. The feelings of her breasts against my naked body, my penis inside her vagina, the pleasure of everything that was happening… god, it was incredible! The feelings got even better as I started fucking her, seeing her breasts wobble in time with my thrusts.

As I fucked my unconscious older sister, I wondered what she would say if she knew I was doing this. Would she basically kill me, or would she enjoy it? Would she think I was a good lover?

I began trying different ways of fucking as I screwed Bre this second time. I tried swiveling my hips, I tried fucking fast, I tried fucking slow, trying to see which way felt the best. I gave up eventually because they all felt really amazing.

I managed to last about five minutes before I came again, my sperm shooting into my sister’s vagina as I held tight onto her nude body. The orgasm seemed even more wonderful and more intense than the first time.

When I pulled out of Bre, I looked at the clock on the wall and knew that it was getting to the point where I’d have to stop. I pulled my boxers back on and spent the next several minutes trying to get her back into her clothes before realizing what a losing battle this was. A bit of panic set in, because I knew I certainly couldn’t have her waking up naked in the living room.

So it was that I gathered up my sister’s clothes and, with great effort, managed to get her upstairs and into her own bedroom. I figured if she woke up naked in her bed, she’d figure that she’d just ended up there when she passed out. I knew she sometimes slept naked, so that wouldn’t be so odd.

I also took a chance to fuck her once more, this time with her bent over her bed, so that I entered her from behind and fucked her doggie-style, adding one more blast of incestual sperm to the two that were already inside her. Then I quickly went back to my own bedroom where I ended up having to jerk off before I fell asleep.

The next morning, after my sister woke up, she didn’t say anything about anything being odd. To say that I was relieved was an understatement. In fact, she never said anything about knowing what had happened the previous night or even suspecting anything. I’d gotten away with it!

I was fortunate enough to have my sister pass out on me a couple more times and took both chances to fuck her. Once she did it when a friend of mine, who was still a virgin, was staying the night, and I let him do her, too.

Looking back on it, I know what a stupid, wrong thing this all was. Still, if I knew then what I know now and had the chance to do it over again… well…
