The house was quiet except for the wet sounds coming from the living room. Mom had her legs spread wide on the couch, her big tits bouncing as her son pounded into her. "Fuck me harder, baby," she growled, gripping his ass and pulling him deeper. "Give your mom that thick cock."
Her daughter was on the floor on all fours, her brother behind her slamming his dick into her tight pussy. "That's it, bro, wreck your sister's cunt," she moaned, pushing back against him.

"I want your cum too."
They had started with the videos that afternoon. The four of them had gathered around the laptop, watching clip after clip of real family incest scenesmoms getting creampied by their sons, brothers unloading in their sisters. It got them all hot and ready to make their own.
Mom came first, her pussy clenching around her son's shaft. "Fill me up," she begged. "Pump that hot load right in your mom's cunt." He groaned and buried himself to the balls, shooting thick ropes of cum deep inside her. When he pulled out, the creampie oozed out, dripping down her ass.
The brother saw it and lost control. He grabbed his sister's hips and fucked her faster. "Take it, sis," he grunted. "I'm gonna creampie you just like mom got creampied." He thrust one last time and unloaded, flooding her pussy until cum leaked out around his cock.
Mom crawled over and pushed her face between her daughter's legs, licking the fresh creampie from her son's load. "Tastes so fucking good," she said, then turned and sucked her other son's softening dick clean.
The brother pulled out of his sister and moved behind his mom, sliding into her cum-filled hole for round two. The sister sat on her mom's face while her brother fucked her from behind again. They kept going, switching holes and positions, everyone getting creampied multiple times.
By the end of the night the couch was soaked, and the four of them were lying in a sweaty, cum-covered pile, already planning which video to watch next before they went at it again.
