Mike slammed the door behind him, dick already hard from what he'd walked in on. His sister Lisa was on her knees in the living room, mouth wrapped around their younger brother Jake's cock while Jake's girlfriend Tara fingered Lisa from behind. All three were naked, sweaty, and clearly not stopping for him.
"Fuck, don't just stand there," Lisa said, pulling off Jake's dick with a wet pop. "Get over here and join in or get out."
Mike stripped fast. His cock sprang free, thick and veiny. Tara looked up and grinned.
"Told you he'd be into it." She pulled her fingers from Lisa's cunt and licked them clean.
Lisa crawled over to Mike on all fours, grabbed his shaft, and swallowed him to the root in one go. Her throat squeezed tight around him. Jake moved behind her, spread her ass, and shoved his cock into her pussy without warning. Lisa moaned around Mike's dick, the vibration making his balls tighten.
Tara climbed onto the couch, spread her legs, and pulled Mike's head between her thighs. "Eat me while your sister sucks you." Mike buried his face in her wet cunt, tongue fucking her hole while his nose rubbed her clit. She tasted sharp and clean. Jake pounded Lisa harder, skin slapping loud in the room.
Lisa pulled off Mike's cock and looked up at him, spit dripping from her chin. "You want to fuck your sister too?" She turned around, presented her dripping pussy to him, and wiggled her ass. Mike didn't hesitate. He lined up and slammed into her in one thrust. Lisa cried out and pushed back, taking every inch.
Jake stood in front of her now, feeding his cock back into her mouth. Tara slid down beside them and started licking Mike's balls while he fucked Lisa. Every thrust made Lisa's cunt clench. Jake grabbed Lisa's hair and fucked her face rough, making her gag and drool.
"Switch," Tara ordered. She pushed Mike out of Lisa and took his place, sucking his cock clean of his sister's juices. Jake pulled out of Lisa's mouth and dropped behind Tara, sliding into her ass in one smooth motion. Tara grunted but pushed back, taking it deep.
Lisa stood, turned Mike around, and bent him over the arm of the couch. She spread his ass and licked his hole without asking. Mike groaned, pushing back against her tongue. Jake watched while he fucked Tara's ass, eyes dark. "You gonna let your sister eat your ass while I watch?"
Lisa stood up, spat on Mike's hole, and worked two fingers inside him. She found his prostate fast and rubbed it hard. Mike's cock jerked and leaked. Tara reached under him and stroked his dick in time with Lisa's fingers.
"Fuck, I'm gonna come," Mike warned. Lisa pulled her fingers out, lined her pussy up again, and sank down on him reverse cowgirl style. Jake pulled out of Tara and moved to Lisa's mouth once more. Tara got behind Jake, spread his ass, and started eating him while he throat-fucked their sister.
The room filled with wet sounds, moans, and the slap of skin. Lisa rode Mike hard, grinding her clit against his balls on every downstroke. Tara switched to fingering Jake's ass while she licked his taint. Jake came first, shooting down Lisa's throat. She swallowed most of it but some spilled down her chin onto Mike's chest.
Mike flipped Lisa onto her back on the floor and fucked her deep, legs over his shoulders. Tara straddled Lisa's face and rode her tongue while Jake recovered enough to slide into Tara's cunt from behind. The four of them moved together, a sweaty tangle of bodies and filthy words.
Mike came hard inside Lisa, pumping thick ropes into her. The feeling pushed Lisa over, her cunt pulsing around him. Tara followed seconds later, grinding on Lisa's face and soaking it. Jake pulled out and painted Tara's ass with his second load.
They stayed like that for a minute, breathing hard, cum and spit everywhere. Lisa looked up at Mike with a lazy, satisfied smile. "Told you family nights were better this way."
