I slammed the door behind me and there she was, my little sister Lisa, bent over the kitchen counter in nothing but a tiny tank top and thong. She was 22, legal as fuck, and we both knew this had been coming for years. "You left your door open last night," she said without turning around. "I heard you jerking off moaning my name."
I didn't waste time with bullshit. I stepped up, grabbed her hips, and ground my already hard cock against her ass. "Yeah? You like that, you dirty little slut? Been wanting your brother's dick?"
She pushed back hard. "Shut up and fuck me. I've been wet all day thinking about it."
I yanked her thong down and shoved two fingers straight into her pussy. She was soaked, dripping down my hand. "Fuck, Lisa, you're dripping for it." I finger-fucked her fast and rough while she moaned and spread her legs wider. Her clit was swollen and she came quick on my fingers, legs shaking.
"Get on the floor," I ordered. She dropped to her knees, yanked my shorts down, and swallowed my cock in one greedy gulp. No teasing, just hot wet mouth sucking hard, tongue swirling around the head while she looked up at me with those filthy eyes. I fucked her face, holding her hair, thrusting deep until she gagged and spit ran down her chin. "That's it, take your brother's cock like the incest whore you are."
She pulled off gasping. "Bedroom. Now. I want you to pound me."
We didn't make it to the bed. I bent her over the couch, spread her ass, and drove into her pussy in one hard thrust. She screamed and pushed back, taking every inch. Her cunt was tight and hot, clenching around me. I fucked her like an animal, hips slapping loud, balls hitting her clit with every stroke. "Harder, fuck me harder, fill your sister's pussy," she begged.
I reached around and rubbed her clit while I pounded her. She came again, screaming, pussy pulsing and flooding my cock. I didn't stop. I pulled out, flipped her onto her back on the couch, and slammed back in, watching her tits bounce under that thin tank top. I ripped it up and sucked her nipples hard while I kept thrusting deep.
"Want it in your ass?" I growled. She nodded, eyes wild. I pulled out, spit on her tight hole, and worked my cock in slow at first then faster. She whimpered and begged, "Deeper, stretch my ass with that big brother cock." I gave it to her, fucking her ass raw while she fingered her own clit and came again, body shaking.
We switched positions all night. She rode me reverse, ass bouncing on my dick.
I fucked her on the kitchen table, legs over my shoulders, pounding her pussy until she squirted. We sixty-nined on the floor, her sucking my cock while I ate her cunt and ass. When I finally came, I pulled out of her ass and shot thick ropes across her tits and face. She licked it up, smiling like the filthy girl she was.
We didn't stop until morning. She woke me up with her mouth on my cock again, and we went another round in the shower, me fucking her against the wall while hot water ran over us. By the time we were done, we were both marked up, sore, and grinning like we had the dirtiest secret in the world. And we did. This was just the start.
