The house was quiet until it wasn't. Jake walked in from college break and found his sister Emma bent over the kitchen table, skirt hiked up, while their dad pounded into her from behind. "Fuck, dad, harder," Emma grunted, her tits mashed against the wood. Jake froze for a second, cock twitching in his jeans, then kicked the door shut and unzipped.
"Room for one more?" he asked, already stroking his thick shaft.
Their mom appeared from the hallway, naked, nipples hard. "About time you joined us," she said, dropping to her knees and swallowing Jake's cock in one wet gulp. She sucked like she was starving, spit running down his balls while dad kept railing Emma, the wet slap of skin on skin filling the room.
Emma looked back, eyes glazed. "Jake, get over here and fuck my mouth while dad wrecks my pussy." Jake pulled out of his mom's throat with a pop and stepped up. Emma opened wide, taking him deep until her nose hit his pubes. Dad slammed in harder, making her moan around Jake's dick, the vibration shooting straight to his balls.
Mom stood and bent over the counter next to her daughter. "Don't leave me out, son. Stick that cock in your mother's cunt." Jake pulled free of Emma's mouth, lined up behind mom, and drove in balls-deep. She was soaked, gripping him tight. He fucked her rough, hips snapping, while dad did the same to Emma. The two women reached over and fingered each other's clits, moaning in sync.
Dad pulled out and flipped Emma onto her back on the table. "Your turn, boy. Fuck your sister raw." Jake yanked out of mom and sank into Emma's dripping hole. She wrapped her legs around him, heels digging into his ass. "Fill me up, brother. Pump that cum in me." Jake hammered her, the table creaking, while dad fed his cock into mom's mouth.
They switched again. Mom climbed onto the table and straddled Emma's face. Emma licked her mom's pussy like she was dying for it, tongue fucking her hole. Dad got behind Jake and pressed his cock against Jake's ass. "Ever taken it here, son?" Jake nodded, pushing back. Dad shoved in, stretching him open, and the three of them moved togetherdad fucking Jake, Jake fucking Emma, Emma eating mom.
Cum started flying. Dad unloaded first, flooding Jake's ass. Jake felt it and blew deep in Emma's cunt, rope after rope. Mom came on Emma's tongue, thighs shaking, then slid down to suck Jake's load out of her daughter's pussy. They kept going, swapping holes, everyone filthy and loud, until the kitchen smelled like sex and sweat.
By the end they were sprawled on the floor, bodies slick, still touching and groping. Dad grinned. "Welcome home, Jake. This is how we do family now." Emma licked cum off her lips and winked. "Next round's in the bedroom. Don't keep us waiting."
