The house was quiet except for the wet sounds coming from the living room. Jenna, eighteen and freshly home from college, had her stepbrother Mark's thick cock buried in her throat. She gagged on it loud and sloppy, spit running down her chin onto her bare tits while her stepdad watched from the armchair, stroking his own hard dick.
"Fuck, that's it, suck your brother's cock like the family slut you are," Mark growled, gripping her hair and thrusting deeper. Jenna moaned around him, her pussy dripping onto the carpet. She had started this months ago, the first time her mom was out of town. Now it was the new normal whenever the three of them were alone.
Her stepdad stood up and walked over, slapping his heavy cock against her cheek. "Open wider, baby girl. Daddy wants that mouth too." Jenna pulled off Mark's dick with a pop and turned, taking her stepdad's shaft straight down her throat in one go. She worked them both in turns, jerking one while sucking the other, her tongue swirling around the heads, tasting precum and her own spit.
Mark dropped to his knees behind her and shoved two fingers into her soaked cunt. "She's fucking drenched. Always ready for family cock." He lined up and slammed into her from behind, making her scream around her stepdad's dick. The slap of skin on skin filled the room as he pounded her hard, his balls swinging against her clit with every thrust.

Jenna pushed back, taking every inch. "Harder, Mark. Fuck your stepsister's pussy raw." Her stepdad pulled out of her mouth and moved underneath her, sucking on her swinging tits while she rode Mark's cock. She came hard, her walls clenching, juices squirting down Mark's thighs.
They switched positions fast. Her stepdad took her ass while Mark fucked her pussy, stretching her tight holes at the same time. Jenna howled, loving the burn and the fullness. "Fill me up, both of you. Cum in your little family whore."
Mark came first, pumping thick ropes deep into her cunt. Her stepdad followed seconds later, unloading in her ass. Cum leaked out of both holes as they pulled free. Jenna stayed on all fours, panting, then reached back to scoop some of the mess and lick it off her fingers.
"Round two in the shower?" she asked, voice hoarse but hungry. The men grinned and hauled her up, already getting hard again.
