The house ran on one simple rule: if a cock was hard or a pussy was wet, someone was getting fucked right then. No asking, no stopping, no bullshit.
I woke up with my dick already throbbing against my sister's ass. Emma was 20, still half-asleep on her stomach, and I just yanked her panties aside and shoved in. She grunted but pushed back, taking every inch like she always did. "Morning load already?" she mumbled into the pillow. I didn't answer, just pounded her sloppy cunt until I pumped her full and left her leaking on the sheets.
Downstairs Mom was making coffee, naked except for an apron. Her big tits swayed as she stirred. Dad had her bent over the counter, balls-deep in her ass while she poured his cup. "Morning, son," he said without missing a stroke. Mom looked over her shoulder and smiled. "Your sister's cunt still tight this morning?"
I grabbed Mom's tits and squeezed while Dad kept wrecking her. "Tight enough. I left her dripping." Mom moaned when I pinched her nipples hard. Dad finished with a grunt, filling her ass, then pulled out and slapped her ass cheek. "Your turn if you want it," he told me, zipping up like it was nothing. Mom stayed bent over, cum running down her thighs. I dropped my shorts and drove straight into her pussy. She was soaked from Dad's load and her own juice. I fucked her rough and fast, slapping her ass red while she braced on the counter. When I came she clenched around me and sighed. "Good boy. Fill Mommy up."
Emma wandered in, my cum still sliding down her leg. She dropped to her knees without a word and started licking Mom's pussy while I was still inside her. Mom grabbed the back of Emma's head and ground on her tongue. I pulled out and fed my cock to Emma instead. She sucked me clean, tasting both of us, then stood up and bent over next to Mom.
Dad was already on his phone checking work emails when I slid into Emma again. He glanced up once. "Don't forget we have company coming for dinner. Make sure both girls are full before they get here." Mom laughed and reached back to spread her ass. "You heard him. Plug me too." I switched holes, fucking Mom's cum-filled ass while Emma fingered herself beside us.
By lunch the whole house smelled like sex. I found Emma in the living room riding Dad's cock on the couch. She was bouncing hard, tits flying, while Dad thumbed her clit. Mom was on the floor with her face buried in Emma's pussy from below, licking wherever Dad's cock stretched her. I walked over, grabbed Mom's hips, and slammed into her from behind. She moaned into Emma's cunt. We stayed like that for a while, just using each other, switching holes when we felt like it. Dad came in Emma's ass. I came in Mom's pussy. Emma came on both our cocks. Then we wiped off and went back to normal like nothing happened.
Dinner with the neighbors was the usual game. They had no idea. Mom served food wearing a short dress with no panties. Every time she bent over, her used holes showed. I fingered her under the table while she talked about the weather. Emma jerked me off under the tablecloth until I shot in her hand, then licked it clean between courses. Dad kept a straight face the whole time. After the neighbors left, Mom locked the door and stripped. "Finally. Time for the real meal."
We moved to the bedroom. Mom got on all fours. Emma climbed under her in 69. Dad took Emma's mouth while I took Mom's pussy. We fucked them like that for hours, rotating. Mom came first, shaking and squirting on Emma's face. Emma followed when Dad choked her on his cock and I pounded her from behind. We kept going until both girls were glazed and sloppy, cum leaking from every hole. Dad finished in Emma's ass again. I finished down Mom's throat. She swallowed every drop and showed me her empty mouth.
We collapsed in a pile on the bed, bodies sticky, breathing hard. Mom reached over and lazily stroked my soft cock. "Good day," she said. Emma just hummed and nuzzled Dad's balls. No one moved to clean up. We didn't need to. Someone would wake up hard or wet soon enough, and it would start all over again. That was the rule. That was the house. Freeuse. No refusals. Just family and fucking.
