We were alone in the house again, just like every fucking weekend when our parents took off. I was twenty-two, she was twenty, and the tension had been building for months. She'd walk around in those tiny shorts that barely covered her ass, bending over in front of me on purpose. Tonight she wore nothing but a thin tank top and panties, nipples poking through the fabric like she wanted me to stare.
"Stop looking at me like that, bro," she said, but her voice had that teasing edge. She knew exactly what she was doing.
I grabbed her wrist and pulled her close. "You keep flashing that pussy at me and expect me to ignore it? No more games."
She didn't pull away. Instead she pressed her body against mine, feeling my cock already hard against her stomach. "Then do something about it," she whispered.
I shoved her back onto the couch and yanked her panties down. Her cunt was shaved smooth and already wet, lips puffy and glistening. I dropped my pants and my dick sprang out, thick and veined. She spread her legs wide without a word.
"Fuck me," she said. "Fill your sister's cunt."
I slammed into her in one thrust. She was tight, hot, and soaking. Her walls gripped me like a fist as I started pounding her. The couch creaked under us. Skin slapped on skin. She moaned loud, begging for more.
"Harder, fuck your little sister harder. Wreck that pussy."
I grabbed her hips and drilled deep, balls slapping her ass with every stroke. She clawed at my back, legs locked around me. Her juices coated my shaft, making wet squelching sounds every time I bottomed out.
I flipped her over, ass up, face down. I spread her cheeks and drove back in, watching her asshole wink as I fucked her sloppy hole. She pushed back, meeting every thrust.
"God yes, cum in me. I want your load deep in my cunt."
That pushed me over. I buried myself to the hilt and exploded. Thick ropes of cum pumped straight into her womb, pulse after pulse. Her pussy milked me, squeezing every drop. When I finally pulled out, a heavy white creampie oozed from her stretched slit, running down her thighs in thick streams.
She reached back, scooped some on her fingers, and licked it clean. "More tomorrow," she said, already pushing her ass back for round two.
