I have a sister, Evelyn. 19 years of age, Evelyn is two years younger than me. She is a good girl, always getting high grades, not at all the party-type. She and her geeky friends usually hang out in one of their rooms on weekends, doing who-knows-what.

Evelyn is a very pretty girl, too, although she doesn’t realize, and definitely doesn’t act like it. I don’t know how she does it, but she’s always had this amazing body. Now, I happen to be a sucker for bodies.

It has taken me a while to accept the fact that she turns me on. At first, I tried killing any unholy thoughts right when they popped into my brain, and succeeded most of the time. But the older Evelyn got, and the more her body started to look like that of a woman instead of that of a girl, ignoring her looks wasn’t so easy any more.

As soon as I realized I couldn’t resist, I became obsessed. I would look at her for hours on trips to the beach. I’ve taken hundreds of pictures while she was getting a tan in the garden. And it became worse. I snuck into her room at night to look at her wearing pajamas, or, in summer, just underwear. I spied at her when she was taking showers, climbing on a chair to be able to look through the tiny window. I searched for hidden folders on her laptop when she was out, hoping to find the slightest evidence of her having a naughty side, but failed every time. I had to be happy with my own observations. But I wasn’t.

One very hot week in summer, when my parents were on vacation, I decided I had to take matters into my own hands. Obviously, I couldn’t just ask her if she was interested in not being brother and sister for one night. I needed to persuade her with something more tenacious. I got online and ordered something I never thought I’d ever order.

The day the package arrived, Evelyn and I had pizza together. After we were done, I went to the kitchen to get us something to drink, before we would clean up. I took the little tube out of my pocket and emptied it in her glass, then brought it to her. She drank all of it, thirsty as she must have been.

After a while, she started to look tired. She didn’t feel so good, she said. I let her lean on me and brought her upstairs, to her bedroom. Seconds after she laid down on her bed, she fell asleep. Evelyn was gone, and she would be for hours to come.

I started with undressing her. I was rather surprised to see she was wearing a thong, as I would have thought she was more of a shorts-person. As I took it off, I was even more surprised. I gazed upon a perfectly bald pussy, two symmetrical cushions separated by an invisible abyss. I slowly ran my finger over them. It felt amazing touching my sister like this.

When I got her completely naked, I unbuttoned my jeans and freed myself. The sight of Evelyn’s naked body had already gotten me way beyond half-hard, but I only grew to full proportions when I ran the tip of my dick over her dry lips. She opened her mouth by herself, just enough for me to slide the tip in. I fucked her mouth, very gently, while my hand wandered down her body and between her legs. I had no idea whether she could get wet at all in these kinds of circumstances.

I couldn’t wait any longer. This was the moment I had been thinking about every single night for the past few years. I sat down between her legs and spread them widely, gazing at her helpless body. Running my dick over her pussy lips was only a tease to me. I placed my hands on both sides of her hips and moved forward. It took some force to break the initial barrier, but not nearly as much as I had thought. Maybe my little sister wasn’t that much of a saint after all.

I entered her body deeper and deeper, each time pulling out some of her juices to make it easier the next time, until I was fully inside her. I paused for a moment, realizing I was finally fucking my gorgeous sister. She was lying there, motionless, her face showing no emotion whatsoever. I let myself slide out until only the very tip was still between her lips, then slammed my body forward. Nothing. Not even a flinch. Evelyn was out, and she would be for another good while.

I placed my hands under her armpits and started to fuck her. The only movement in her body was because of me. I wiggled my knees underneath her legs, pushing them up slightly, giving myself a bit more room to work with. With every thrust, my legs got deeper under hers. I could feel her spread, and, to my surprise, I could feel it getting easier to force myself inside her. No longer did I have to do all the work, for her pussy was definitely starting to get moist, and starting to suck me inside. Whether she was subconsciously dreaming about her crush having his way with her, or her body reacted to the feeling it must have had before, I could only guess. All I could think about was my little sister getting wet, and not only that, but getting wet because of me fucking her.

It was a bit of a hassle to flip her around. I pushed her legs together and spread her butt cheeks, leaving only a tiny gap in which not much more than just my dick would fit. The angle was awkward, and I had to pull her hips up a tiny bit, but eventually, I managed to squeeze myself back in. Carefully, I started pushing my hips forward, but when I got the hang of it, I could up the speed – and the power. I was deep enough inside her to put each of my knees on either side of her waist without slipping out. The pressure wouldn’t have allowed me to do so anyway, and if I would have, my dick would have slammed into my lower belly with quite some force. But it didn’t.

Oh, how I would have loved to get my dick out and unload all over her ass, her back, perhaps even her hair if I could reach it. That thought itself almost made me do it. But something was holding me back; the sudden realization that I could never forgive myself for wasting wave after wave of cum. To see it land on her body, to have to clean it up, to make sure there weren’t any traces. In a moment of clear brain functionality, I decided I had to hide the evidence. And I had to hide it in the only place I could think of.

I turned Evelyn around once more. Her body was lying in front of me, her legs hanging loosely to the sides. I had already passed the point of no return, and I had to move fast. I fell down on top of her and tried to find the hole, poking her lips a few times more than I had wanted to. Just in time, I felt the opening. I was still busy working my way inside her when the first wave hit. I pushed myself as deeply into her as I could. My shoulder covered her mouth as I felt myself unload inside her, my hips shaking as I tried to squeeze every last drop out. I laid on her for what seemed like ages, but only could have been a couple of seconds, before my brain came back to solid ground and went straight to damage control mode.

After pulling out, I used the bottom edge of the blanket to clean her up. Praying everything else would stay inside, I slid her panties back over her legs. It took me ages to get her bra back on. Having no idea in what position she spent her nights, I moved her onto one side and pulled the blanket over her. I carefully placed her clothes on the chair in front of her desk, stepped out of her room, turned off the light, and closed the door.

The kitchen looked clean, but that wouldn’t be for long. I had been to enough house parties to know what one looks like. I emptied two brand new bottles of wine, put one in the far corner of the counter, and laid one down in the sink. I put some empty beer cans all over the kitchen, got the leftover bits of pizza out of the trash, and placed them in strategic places. Lastly, I threw a few glasses of water over the counter and on the floor.

It was long after midday when I heard her again. I got downstairs just moments after she had, and found her standing in the kitchen, blankly staring.

“We may have had a tad too much to drink,” I said, standing behind her.

“What happened?” she asked.

I paused for a bit, hoping she’d wrongly realize she had crossed a drinking line she had never crossed before.

“Let’s not tell mom, okay?”

She turned around, grabbed my face with both hands and stared right into my eyes.

“If you ever tell her, I will kill you. Understood?”

I couldn’t help but place my right hand on her left hip. The plan had worked. Evelyn would never forgive herself for getting so drunk, and I would never forgive myself for fucking her – and yet we both got what we wanted. I stared back at her, faking a quick look into the kitchen, before holding her face just like she was holding mine.

“Promise.”
