My sister

It all started one random night on the couch.
We were watching a movie late at night and both fell asleep. She was lying on her side in front of me in those tiny white bear-patterned pajama pants. At some point she shifted backwards and her soft, round ass pressed right against my crotch. Her ass was literally resting on my dick. Even through the fabric, the warmth and softness made my cock twitch and start getting hard.
I froze at first. This was my little sister. But I didn’t pull away. Instead, I stayed there, feeling her ass gently move every time she breathed. My cock grew harder and harder until it was throbbing painfully against her. I got so fucking curious… and so horny. I slowly pressed forward just a little, letting my hard dick nestle deeper between her ass cheeks. The feeling was insane. That was the first time I really saw her as more than just my sister. That night I realized I wanted to fuck her. Badly.
After that, I couldn’t stop thinking about it. Every night I jerked off imagining sliding my cock into her.
A few nights later, I finally snuck into her room while she was sleeping. She was on her stomach again, wearing that thin tank top and the same white panties. I pulled her blanket off carefully, then slowly dragged her panties down to her thighs, exposing her bare ass and smooth little pussy.
My heart was hammering. I climbed on the bed, straddled her legs, and pressed my bare cock between her warm ass cheeks. I started rubbing it up and down, letting the head glide over her pussy lips, spreading them slightly with every stroke. She was getting wet. I could feel it.
I got bolder. I leaned down and kissed her soft sleeping lips, then kissed her deeper, sliding my tongue into her mouth while my cock kept rubbing against her slit. She made tiny sleepy noises but didn’t wake up.
Then I did it.
I lined my cock up with her tight entrance, rubbed the head up and down a few times to coat it in her juices, and slowly pushed forward. Just the tip. Her warm, silky pussy opened around my cockhead like velvet. The sensation was next-level — so tight, so smooth, so fucking wrong and perfect at the same time. I groaned quietly as her walls squeezed just the head of my dick.
I only had the tip inside her for a few seconds when she suddenly stirred.
She let out a soft, confused little moan… then her hand moved back, still half-asleep. She grabbed the waistband of her panties and slowly pulled them back up herself, covering her pussy again — trapping my precum between her panties and her slit.
I froze completely, my heart racing. I quickly pulled back and stayed still, watching her.
She shifted a little, let out a sleepy sigh, and went quiet again.
I sat there on the edge of her bed, cock still rock hard and shining with her juices, staring at my little sister’s body.
Do you think she knows?
Did she feel the tip of her big brother’s cock pushing inside her? Did she feel how wet she got? Was she pretending to be asleep… or was she half-awake and too shocked to fully react? The way she pulled her own panties back up like that… fuck, it’s been driving me crazy ever since.
Either way, that moment sealed it. I’m going to fuck her completely. I’m going to breed her. And I don’t care if she knows or not — she’s going to take every inch of her brother’s cock soon.
