The house was quiet until the booze started flowing. Mom, 48 with big heavy tits and a shaved pussy she kept smooth for dad, poured another round for everyone. Dad, 50 and still packing a thick cock, grinned as he watched his 22-year-old son and 20-year-old daughter loosen up on the couch.
"Truth or dare, but the dirty kind," the son said, already rubbing the bulge in his jeans. His sister, legs spread in tiny shorts, smirked and took the dare.
"I dare you to kiss mom's tits," she said.
Mom didn't hesitate. She pulled her top down, letting those fat nipples pop free. The son leaned in, sucking hard on one while his hand slid up mom's thigh. Dad just watched, stroking his cock through his pants.
"Fuck yeah, suck your mom's tit," dad growled. "She's been wet thinking about this all week."
The daughter stood up, stripped off her shorts, and showed her smooth, dripping cunt. "My turn. I want dad's cock in my mouth while brother fucks me from behind."
Nobody argued. Dad dropped his pants, his heavy dick swinging free, and the daughter dropped to her knees, wrapping her lips around the head and sucking loud and sloppy. The son got behind her, yanked her ass up, and slammed his cock straight into her tight pussy. She moaned around dad's shaft, spit running down her chin.
Mom wasn't left out. She got on all fours next to her daughter and spread her ass. "Somebody eat this pussy," she demanded. The son pulled out of his sister long enough to bury his face between mom's cheeks, tongue fucking her wet hole while he fingered her clit.
The room filled with wet sounds: slurping, slapping skin, grunts and filthy talk.
"Harder, fuck your sister like you mean it," dad ordered, holding the daughter's head down on his cock until she gagged.
The son obeyed, pounding into his sister's cunt so hard her tits swung. Mom crawled over and started licking her daughter's clit while the son fucked her, tasting both of them at once. Dad pulled out of the daughter's mouth and moved behind mom, driving his thick cock into her married pussy in one thrust.
They switched partners fast. The son laid back and the daughter climbed on, riding his cock reverse cowgirl so everyone could watch his dick disappear into her. Mom straddled the son's face, grinding her pussy on his tongue while dad fucked her from behind, his balls slapping against the son's chin.
"Fuck, this family pussy is the best," dad grunted, switching holes and shoving his cock into mom's ass. She screamed and came hard, squirting down the son's chest.
The daughter leaned forward and started sucking mom's tits again while getting railed. They moved to the floor in a pile: daughter on her back with the son's cock in her mouth, mom sitting on her face, dad behind the son fingering his ass and then sliding his cock in there too. The son groaned loud around his sister's pussy as dad fucked him deep.
Mom came again, flooding her daughter's mouth. "Swap," she ordered.
They rearranged. Dad fucked his daughter missionary, legs over his shoulders, pounding her cunt while calling her a dirty little family slut. The son took mom doggy style, gripping her hips and slamming into her. Mom and daughter kissed, tongues sloppy, tasting each other's juices.
The orgy went on for hours. They fucked in every combination: mom and daughter scissoring while the men watched and stroked, then the men taking turns on both holes. The daughter got double penetrated, son's cock in her ass and dad's in her pussy, screaming as she came. Mom rode the son's face while sucking dad clean after he came in the daughter.
By the end they were all covered in sweat and cum. Dad pulled out and sprayed thick ropes across mom's tits and the daughter's face. The son unloaded inside mom's cunt, then watched his sister lick it out. They collapsed in a sticky heap on the floor, breathing hard, already talking about doing it again tomorrow.
Mom smiled, cum dripping from her chin. "Next time we bring the cousins."
