The house was empty except for us. Mom and Dad had left for the weekend, and my older sister Lisa, twenty-three and always the bold one, had just come out of the shower with nothing but a towel around her. I was twenty-one, horny as hell, and we both knew the looks we'd been giving each other for months were about to explode.
"Stop staring, little brother," she said, dropping the towel right there in the hallway. Her tits were full and heavy, nipples already hard, and her shaved pussy glistened from the shower. "Or come do something about it."
I didn't hesitate. I grabbed her, spun her around, and bent her over the kitchen table. My cock was rock hard in seconds. I yanked my shorts down and slammed into her wet cunt from behind in one rough thrust. Lisa moaned loud and filthy. "Fuck yes, fuck your sister's pussy. Pound it hard."
I did exactly that. My hips slapped against her ass with every deep stroke. Her tight walls gripped my dick like she was made for it. I reached around and rubbed her clit hard while I fucked her, making her scream my name. "That's it, Jake, fill your sister's hole. We've wanted this forever."
She came fast, her cunt spasming around me, juices dripping down her thighs. I pulled out and spun her to face me, lifting her onto the table so I could suck on those perfect tits while I shoved back inside. Lisa wrapped her legs around me and clawed my back. "Harder. Fuck me like you own me."
We moved to the couch next. She got on all fours and I took her again, spreading her ass cheeks so I could watch my cock disappear into her soaked pussy. I slapped her ass red and told her what a dirty incest slut she was for letting her brother wreck her. She pushed back on every thrust, begging for more. "Cum in me. Breed your sister's cunt."
I exploded deep inside her, pumping load after load until it leaked out around my shaft. But we weren't done. Lisa flipped around, sucked my cock clean, then climbed on top and rode me reverse cowgirl, grinding her clit while my cum-slick dick stretched her again.

She came twice more, screaming about how good family cock felt.
By the time we collapsed, sweaty and spent, the sun was setting. We knew this was just the start of a very long, very hot weekend of raw family fucking.
