The house was quiet except for the wet sounds of skin slapping skin. Mark had his sister Lisa bent over the kitchen table, her shorts around her ankles and his thick cock buried balls-deep in her tight pussy. "Fuck, sis, you're so wet for your brother's dick," he growled, pounding her hard from behind. Lisa moaned loud, pushing back against him. "Yeah, big brother, give it to me rough. I've been thinking about this all week."
Their cousin Jake walked in from the garage, stopping short at the sight. At twenty-five, Jake was no stranger to their games, but tonight his eyes locked on Mark's ass as it flexed with every thrust. "Shit, you two started without me," Jake said, already unbuckling his belt. His cock sprang out, hard and veined, and he stroked it while watching.
Lisa turned her head, grinning dirty. "Get over here, Jake. Mark's been talking about sucking your cock while he fucks me." Mark didn't miss a beat, slamming into her harder. "That's right. Come feed me that dick, cousin.
I want to taste it while my sister's pussy squeezes my shaft."
Jake stepped up to the table. Mark leaned forward, mouth open, and took Jake's cock between his lips without hesitation. He sucked greedily, tongue swirling around the head, while his hips kept driving into Lisa. The three of them moved together in a filthy rhythm—Mark fucking his sister raw, Jake thrusting into Mark's mouth. Lisa reached back and spread her ass cheeks wider. "Deeper, Mark. Fill your sister's cunt."
Mark pulled off Jake's cock with a wet pop, spit dripping down his chin. "You want to switch, Jake? Want to fuck your cousin's ass while I eat Lisa's pussy?" Jake nodded, eyes dark with lust. They shifted fast. Lisa climbed onto the table on her back, legs spread wide. Mark buried his face between her thighs, licking and sucking her swollen clit while Jake positioned himself behind him.
Jake spat on Mark's hole and pushed in slow at first, then harder once Mark groaned into Lisa's pussy. "Fuck yeah, take my cock in your ass," Jake grunted, gripping Mark's hips. Mark's tongue worked faster on Lisa, two fingers sliding into her soaked slit. She bucked against his face, coming hard, juices coating his mouth. "Don't stop, brother. Keep eating me while Jake pounds you."
They kept going, switching positions again and again. Lisa rode Mark's cock reverse cowgirl while Jake fed his dick into her mouth. Then Mark and Jake stood side by side, Lisa on her knees sucking both of them in turn, her tongue sliding from one shaft to the other. "You two taste so good together," she mumbled around their cocks. Mark reached over and stroked Jake's balls, then leaned in to kiss him deep, tongues tangling while Lisa switched between them.
Later, on the living room floor, Jake lay on his back with Lisa straddling his face. Mark knelt between Jake's legs, sucking his cousin's cock while Jake licked Lisa's pussy. The room filled with moans and the slick sounds of mouths and bodies. Mark pulled off, lined up, and sank his cock into Jake's ass, fucking him steady while Lisa ground down on Jake's tongue. "That's it, take your cousin's dick," Mark rasped. Jake's cock twitched in Mark's fist as he came, shooting across his own stomach.
They didn't stop until all three were spent, bodies slick with sweat and cum. Lisa lay between them, Mark's fingers lazily circling her clit while Jake kissed her neck. "Same time next week?" she asked, voice hoarse. Mark grinned against her shoulder. "Count on it. This family's got plenty more filthy stories to make."
