Fan Fiction ❯ Guilty Pleasures ❯ Guilty Pleasures ( One-Shot )

I watch as my younger sister touches herself. I can’t believe that she’s doing that. But, then again, she is sixteen and therefore about the age that she should start doing things like that. At least for girls. I don’t think they start any sooner.

I, myself, am seventeen and proud of it. But, I don’t know what my fascination is with my own sister. She’s pretty…and available…but not for me. I look through the crack in the door again. I guess she felt safe to leave it open a crack because mom and dad aren’t home.

She slides her fingers over her pussy and I can’t help but get hard at seeing how wet she seems to be. She moans and moves her fingers over her clit faster. I can’t help but want to go over there and stick my own fingers inside her. Hey. A pussy’s a pussy, right?

She stops for a minute and I wonder why until she reaches over and gets her hairbrush and slides the handle inside of herself. She moans and starts to move it in and out. I can’t take it anymore and I go into the room.

She gasps and takes the hairbrush out of her and covers herself up with her blankets. I go over to her.

“I wanna fuck you.” I say, bluntly. She looks at me like I’ve got two heads.

“Have you lost your mind??” She asks.

“No. I’m just horny and I know you are too so lets fuck.” I say, nearly in a pleading tone.

She thinks about it for the longest time and I am about to turn to go because I figure she doesn’t want to when she says, “Okay.”

I nearly fall over with surprise. I was sure she was going to say no. I grin and pull her covers back and then take off my own clothes. No use being overdressed. I get onto the bed with her, but I don’t move over her. I spread her legs further and slide my tongue over her pussy.

She moans and arches her back. Apparently, she’s never had anybody do this before or she’d be a bit more used to it. I flick my tongue over her clit a few times, making her nearly cry out in pleasure at having a warm and wet tongue touch her clit.

I put my mouth over it and start to suck on it, sliding my tongue over it as I do so, eliciting some very interesting moans from her. I could taste and feel her getting wetter and I moaned a bit onto her pussy. I slide my tongue inside her as far as it will go and she cried out my name. God, that was music to my ears. I slid my tongue in and out for a while, listening to her moans get higher in pitch until finally she came, all over my mouth and chin. She moaned and whimpered in pleasure as I licked her.

While I was licking her, I had my cock in my hand and was slowly rubbing it. I didn’t want to cum yet, but I wanted to make sure I was good and hard and ready. I pull my mouth away from her and slide a couple fingers inside her pussy. She slid down on them immediately as I moved them in and out, harder and faster each time I pushed them in. She was moaning and bucking onto them after a while and I continued until I made her come again.

I pulled my fingers out of her and licked them clean, then, finally, I moved over her. I kissed her, so she could taste herself. She moaned and wrapped her arms around me and I guided the head of my cock inside of her. She moaned and wanted to buck onto it, but I held her hips still and slid my cock all the way inside of her. God it felt good to have her warm, extremely wet pussy around my hard cock that was already dripping pre-cum.

I started to move in and out of her and at first I don’t think it did much for her, but when I switched angles and began to thrust harder and faster she started moaning loudly, nearly screaming, digging her nails into my back. I grinned and continued what I was doing, moaning as well but never her name.

I slid one hand down and started to rub her clit while I thrust into her, my balls slapping against the flesh of her ass. She came before I did, but I kept moving in and out of her. She wrapped her legs around my waist so I could get into her deeper. She arched her back and cried out in pleasure. I thrust harder and finally I felt that I was going to cum, so I pulled out of her just as she came again and she made a mess all over the bed, but I didn’t care. I pumped my cock as fast as I could, it was slick with her cum, and I came all over her pussy and thighs. She moaned at the feeling of it on her, saying she wished she’d been able to feel it inside her. But, I hadn’t wanted to make a monster baby so I won’t ever cum inside her.

But, she did say we could do this again sometime. I can’t wait.
