The house always smelled like sex on Sundays. Sweat, cunt, and the thick musk of cum that never quite washed out of the sheets no matter how many loads we pumped into each other. Mom started it years ago, right after my eighteenth birthday, when she caught me jerking off in the shower and decided the family needed to stop pretending.
Get your ass in the living room, she told me that first time, voice low and filthy. Your fathers already hard. Your sisters waiting.
I walked out naked, cock swinging, and there they were. Dad on the big sectional, legs spread, stroking his thick dick while he watched Mom peel her robe off. My older sister, twenty-one and already dripping, was on her knees between his feet, licking the head like shed done it a hundred times. She had.
Mom pushed me down next to Dad and straddled my lap without a word. Her pussy was shaved smooth and already soaked. She sank down on my cock in one smooth motion, groaning deep in her throat as I stretched her open.
Thats it, baby, she breathed against my mouth. Fuck your mother. We stay close this way. We stay together.
Dad reached over and grabbed the back of my neck, pulling me into a rough kiss while Mom rode me hard. Her tits bounced against my chest, nipples stiff. Across from us my sister climbed into Dads lap and impaled herself on his cock with a wet sound that made my balls tighten. She was loud, always had been, moaning Daddy, Daddy, stretch my cunt while she bounced.
We didnt talk about feelings.

We fucked. Moms pussy clenched around me every time Dad slapped my sisters ass. I reached over and grabbed one of my sisters bouncing tits, pinching the nipple the way she liked. She came first, shaking and cursing, pussy squirting down Dads shaft and onto the couch. Mom followed right after, grinding down hard and milking me until I flooded her with thick ropes of cum.
We didnt stop there.
Dad pulled my sister off his cock and pushed her face between Moms legs. Clean your mother up, sweetheart. My sisters tongue went straight to work, licking my cum out of Moms freshly fucked hole while Mom held her hair and moaned. Dad stood behind me, pressed the head of his cock against my hole, and shoved in without asking. I grunted, taking it, used to the burn by now. He fucked me slow and deep while I watched my sister eat Mom out, one hand stroking my own cock back to life.
When Dad came he stayed buried in my ass, pumping me full, then pulled out and fed his cock to my sister so she could taste both of us. Mom turned around, presented her ass to me, and I slid back into her from behind while Dad watched, stroking himself hard again.
We rotated. Mom on her back with my sister sitting on her face. Dad fucking my sister while I fucked Mom. Then Dad and I switching holes, both of us buried in the women at the same time, grunting and slapping skin. The room filled with the wet sounds of fucking, the slap of balls against ass, the filthy encouragement.
Deeper, son. Wreck that pussy.
Take Daddys load, baby girl.
Fuck, Im gonna come again.
We came in every hole, on tits, on faces, across bellies. By the time we finished the sectional was soaked and everyone was sticky and grinning. Mom pulled us all into a pile, bodies tangled, cum leaking everywhere. She kissed me slow, then my sister, then Dad, tasting all of us on her tongue.
Same time next week, she said, voice hoarse. No excuses. Family that fucks together stays together.
And we did. Every Sunday. Sometimes on weeknights too when the need hit. No jealousy, no secrets, just raw, constant, messy fucking that kept us closer than any normal family could ever be. That was the rule. That was the bond. And none of us ever wanted it any other way.
