He slammed the door behind him and grabbed her by the hair the second she turned around. "You knew what you were doing walking around here like that," he growled, yanking her against his chest. His sister, twenty-two and built like sin, tried to twist away but he was bigger, stronger, and already hard from watching her all week.
"No more teasing, little sis. You're getting fucked tonight whether you want it or not."
She fought him, slapping at his arms, but he shoved her face-down over the kitchen table. Her shorts ripped under his hands. He didn't bother with her top, just yanked the fabric aside and drove two thick fingers straight into her cunt. She was wet already. "Fuck, look at that," he snarled, pumping hard. "Your pussy knows who owns it."
He freed his cock and shoved inside in one brutal thrust. She cried out, but he clamped a hand over her mouth and started pounding. The table legs scraped the floor with every slam. He fucked her like he hated her, hips snapping, balls slapping her ass, using her body for every dirty fantasy he'd jerked off to since they were teens. "Take it, slut. This is what happens when you prance around in those tiny shorts. Your big brother's cock owns this hole now."
She moaned into his palm, half protest, half need, but he didn't slow down. He pulled out, flipped her onto her back, and shoved back in while pinning her wrists above her head. Her tits bounced with every thrust. He leaned down and bit her nipple hard enough to make her yelp, then sucked it to soothe the sting before moving to the other. "Scream if you want. Nobody's coming to stop me."
He fucked her through two raw orgasms she tried to fight, her cunt clenching and dripping around his shaft. When he was close he pulled out, dragged her to her knees, and shoved his cock down her throat. She gagged but he held her there, pumping thick ropes of cum straight into her belly. "Swallow every drop, sis. You're mine now."
After he finished he didn't let her up right away. He pushed her onto the floor, spread her legs, and ate her out rough and messy, tongue fucking her while his fingers worked her clit until she came again, shaking and cursing his name. Only then did he haul her up, bend her over the couch, and take her ass for the first time, working lube in with spit and determination until he was buried balls-deep.
They didn't stop until the sun came up. By morning she was covered in his marks, cum leaking from both holes, and too wrecked to pretend she hadn't begged for the last round. He pulled her into his lap on the couch, cock still half-hard inside her, and murmured against her ear, "Next time you try to run, I'll tie you to the bed and invite the whole family to watch." She shivered, but she didn't pull away.
