She walked into the basement knowing exactly what was coming. Her brother stood there shirtless, belt in hand, eyes locked on her like he owned every inch. "Strip, slut," he growled. She peeled off her clothes fast, already wet from the command. He grabbed her wrists and slammed them into the leather cuffs hanging from the ceiling. The click of the locks made her pussy clench.
He circled her, dragging the belt across her tits, then cracked it hard across her ass. The sting shot straight to her clit. "You begged for this, little sister. Family secret stays down here." Another lash landed, then another, until her cheeks burned red. He stepped close, shoved two fingers into her dripping cunt and pumped them rough. "Soaked already. Fucking pathetic."
She moaned loud when he added a third finger, stretching her open while his thumb rubbed her swollen clit. He pulled out, wiped her juices across her face, then unzipped. His thick cock sprang free, veiny and hard. He forced it between her lips, fucking her throat deep until she gagged and drooled down her chin. "Take it all, whore. You know you want your brother's cum."
He pulled back and spun her around, bending her at the waist. The cuffs kept her arms high. He lined up and slammed his cock into her pussy in one brutal thrust. She cried out, body jerking as he pounded her hard, balls slapping against her. Each stroke hit deep, the wet sounds filling the room. He reached around, pinched her nipples viciously, twisting until she whimpered.
"Harder," she begged. He laughed low and filthy, then pulled out and pressed the head against her tight asshole. Spit landed on her hole before he pushed in slow but steady, stretching her ass open around his shaft. She gasped at the burn and the filthy fullness. Once buried, he started fucking her ass with the same savage rhythm, one hand fisting her hair, the other slapping her already sore ass cheeks.
He reached for the clamps on the table, snapped them onto her nipples, and tugged the chain while he railed her. The pain mixed with pleasure until she was shaking. "Come on your brother's cock," he ordered. She shattered, pussy squirting around nothing, ass clenching tight on his dick.
He kept fucking through it, using her until his rhythm broke. With a grunt he buried deep and pumped hot cum into her ass, filling her until it leaked out around his shaft.
He stayed inside her a moment, breathing heavy, then uncuffed her wrists. She dropped to her knees, licking his cock clean like the good girl he trained her to be. "Same time tomorrow," he said, voice still rough. She nodded, already aching for more.
