I walked into the kitchen and there she was, my sister, bent over the counter in nothing but a tiny tank top and panties, her ass cheeks peeking out like she wanted me to notice. "Fuck, sis," I said, my cock already twitching in my shorts. "You know what that does to me."
She turned, smirking, nipples hard against the thin fabric. "Then do something about it, big brother. We've got the house all weekend."
I didn't waste time. I grabbed her hips and spun her around, yanking those panties down to her knees. Her pussy was already wet, glistening. I shoved two fingers inside her hard, pumping them while she moaned and pushed back against my hand. "Yeah, finger that tight cunt," she hissed. "Make your sister drip for your dick."
I pulled my cock out, thick and throbbing, and slammed it into her from behind in one thrust. She cried out, gripping the counter as I fucked her raw, skin slapping loud in the kitchen. Her pussy clenched around me, hot and slick, taking every inch. I reached around and rubbed her clit fast, dirty words spilling out. "This is what you want, right? Your brother's cock pounding your slutty hole. Tell me how much you love incest dick."
"Fuck yes," she gasped. "Harder. Wreck your sister's pussy."
I pounded her until she came, legs shaking, juices running down her thighs. Then I pulled out, spun her to face me, and pushed her to her knees. She sucked me greedily, tongue swirling around the head before taking me deep, gagging as I fucked her throat. Spit dripped down her chin while she looked up at me with those filthy eyes.
We moved to the couch next. I laid her back, spread her legs wide, and buried my face between them, licking and sucking her swollen clit until she begged for my cock again. I slid in slow at first, then built to a brutal rhythm, her tits bouncing with every thrust. "Cum inside me," she demanded.
"Fill your sister's cunt with that load."
I did, grunting as I pumped rope after rope deep in her, feeling her walls milk me dry. We didn't stop there. Later that night she rode me reverse, ass bouncing on my cock while I slapped it red. She reached back and spread her cheeks, letting me watch my dick disappear into her again and again. By morning we were in the shower, her bent over the bench while hot water ran over us, my fingers in her ass and cock in her pussy, stretching both holes until she screamed my name.
We kept going all weekend, every room, every position, raw and nasty, just brother and sister fucking like animals with no rules left.
