Jake slammed the front door behind him, cock already half-hard from the filthy texts his sister had been sending all day. He found her and their older brother Mark in the living room, both naked on the couch, her mouth stretched around Mark’s thick dick while Mark’s fingers pumped between her spread thighs.
“Fuck, finally,” Lisa moaned, pulling off Mark’s cock with a wet pop. “Get over here, little brother. I want both of you inside me tonight.”
Jake stripped fast, his dick springing free. Mark grinned at him, that same hungry look they’d shared since they were teens sneaking around their parents’ house. “Come suck me while I eat her out,” Mark ordered.
Jake dropped to his knees between Mark’s legs. He wrapped his lips around his brother’s fat head, tasting Lisa’s spit and Mark’s precum. Mark groaned and pulled Lisa onto his face, tongue driving straight into her soaked pussy. Lisa reached down and grabbed Jake’s hair, forcing him deeper onto Mark’s cock until he gagged.
“Goddamn, you two look good like that,” she panted. “Suck your brother’s dick, Jake. Get it nice and wet so he can fuck me while you watch.”
They moved fast after that. Mark flipped Lisa onto her back on the rug, spread her legs wide, and slammed into her in one thrust. Jake knelt behind Mark, spreading his brother’s ass and burying his tongue in Mark’s hole the way he knew drove him crazy. Mark fucked Lisa harder, grunting every time Jake’s tongue pushed inside him.
“Switch,” Lisa demanded. “I want Jake’s cock in me. Mark, get behind him.”
Jake sank into his sister’s tight, dripping cunt with a long, filthy groan. She was so wet he bottomed out immediately. Mark pressed up behind him, rubbing the head of his cock against Jake’s hole, then pushing in slow and steady until Jake was sandwiched between them—his dick buried in Lisa, Mark’s dick buried in him.
They found a rhythm fast. Every time Mark thrust forward, he drove Jake deeper into Lisa. Lisa’s nails raked down Jake’s back. “Harder,” she begged. “Fuck me like you mean it. Both of you.”
Mark grabbed Jake’s hips and pounded into him, balls slapping. Jake reached down and rubbed Lisa’s clit in fast circles, feeling her pussy clench around him. “Gonna come,” she gasped. “Don’t stop—fuck—don’t fucking stop.”
She came hard, shaking and squirting around Jake’s cock. The feeling pushed him over the edge. He buried himself deep and unloaded inside his sister, pulse after pulse of hot cum. Mark kept fucking him through it, then pulled out, stroked twice, and painted Jake’s ass and lower back with thick ropes of cum.
They collapsed in a sweaty, sticky pile on the rug.
Lisa reached between them, scooping up some of the mess and licking her fingers clean. “Round two in the shower,” she said, voice hoarse. “I want to watch you two fuck each other while I sit on someone’s face.”
Mark laughed low and dirty. “You heard her, Jake. Get that dick hard again.”
