I had just turned twenty-one and my sister Emma was nineteen when it finally happened. We were both home from college for the summer, stuck in the same house with our parents gone for the weekend. Emma had always been the hot little tease, parading around in tiny shorts and tank tops that showed off her perky tits and round ass. I jerked off thinking about her tight body almost every night, but I never thought I'd actually get to shove my cock inside her.
That Friday night we got drunk on the couch watching some stupid movie. Emma was in nothing but a thin white tank top and pink panties, her nipples poking through the fabric. She caught me staring and smirked. "You keep looking at me like you want to fuck me, big brother," she said, her voice low and dirty. I didn't deny it. I just grabbed her and kissed her hard, shoving my tongue into her mouth.
She moaned and climbed onto my lap, grinding her pussy against my hard cock through my jeans. "I've wanted this too," she whispered. "Fuck me. Fill my tight little vagina with your cum." Those words made my dick throb. I ripped her tank top off and sucked on her tits while she dry-humped me. Then I yanked her panties aside and slid two fingers into her soaking wet cunt. She was tight as hell, gripping my fingers like she was made for it.
I carried her to the bedroom, threw her on the bed, and stripped. My cock was rock hard and leaking precum. Emma spread her legs wide and pulled her knees back, showing me her shaved pink pussy. "Come on, brother, fuck your sister's tight vagina," she begged. I climbed on top and rubbed the head of my dick up and down her slit, teasing her clit before I pushed in.
She was so fucking tight it took a few thrusts to get all the way inside. Her vagina walls squeezed my shaft like a vice, hot and wet and perfect. I started pounding her hard, the bed slamming against the wall with every thrust. Emma moaned loud, "Yes, fuck me deeper, cum in my tight vagina!" I grabbed her hips and slammed into her, balls slapping against her ass. Her pussy juices coated my cock and ran down to her asshole.
I flipped her over and took her from behind, doggy style, watching my dick disappear into her stretched hole. I reached around and rubbed her clit while I fucked her raw. She came first, screaming and clenching around me, her vagina pulsing and milking my cock. That pushed me over the edge.
I buried myself balls deep and exploded, pumping thick ropes of cum straight into her tight vagina. It overflowed and leaked out around my shaft as I kept thrusting through my orgasm.
We didn't stop there. I pulled out and watched my cum drip from her used pussy, then I shoved back in and fucked another load into her. Emma begged for it the whole time, telling me how she wanted her brother's cum flooding her womb. We spent the whole weekend fucking in every room, me cumming inside her tight vagina over and over until she was leaking my seed constantly. By Sunday night her pussy was swollen and sore but she still begged for one more creampie before our parents got home.
It became our secret. Every time we were alone after that, I'd bend her over and dump load after load into her. She loved feeling my cum deep in her tight vagina, loved the risk of it. Raw, filthy, and exactly what we both craved.
