She showed up at his door exactly when he told her to, wearing nothing under her coat but a thin black thong and heels. The second she stepped inside he grabbed her by the hair and shoved her to her knees.
"Strip," he ordered. His voice was flat and hard. She dropped the coat, kicked off the heels, and peeled the thong down her thighs. He didn't wait for her to finish before he kicked her legs apart and slapped her bare cunt hard enough to make her gasp. "Already wet. Fucking slut."
He dragged her by the hair into the living room. Ropes were already laid out on the table. He tied her wrists behind her back first, then bent her over the arm of the couch and spread her ass cheeks. One thick finger pushed straight into her asshole without warning. She grunted but stayed still the way he'd trained her.
"Count," he said, and brought the leather strap down across both cheeks. The crack echoed. She counted out loud, voice shaking after the tenth. By the twentieth her ass was burning and her pussy was dripping down her thighs. He stopped only to shove two fingers into her cunt and fuck her with them until she was panting and trying not to come.
"Not yet," he warned. He pulled his cock out, thick and already leaking, and shoved it into her mouth. She gagged when he hit the back of her throat but he held her head and fucked her face anyway, spit running down her chin onto her tits. Every few thrusts he pulled out and slapped her face with his wet cock before shoving it back in.
When he was ready he flipped her onto her back on the floor, tied her ankles to her wrists so she was spread wide and helpless, then slammed into her cunt in one rough thrust. She cried out. He didn't slow down. He fucked her like he owned her, balls slapping her ass, one hand around her throat, the other slapping her tits until they were red and sore. Every time she got close he stopped moving and just ground against her clit until she begged.
"Please, Sir.

Please let me come."
He laughed once, low and mean, then started pounding again. "Come on my cock then, you filthy bitch." She came hard, cunt clenching around him, whole body shaking. He didn't stop. He kept fucking her through it until she was whimpering from oversensitivity, then pulled out and shoved back into her ass. The stretch burned but she took it, moaning like the whore he called her.
He used her ass until he was close, then pulled out and painted her face and open mouth with thick ropes of cum. Some landed on her tongue; she swallowed without being told. He left her tied like that for a while, cum drying on her skin, holes aching and used, while he drank a beer and watched her.
Later he untied her, cleaned her up roughly with a wet cloth, and pulled her into his lap on the couch. His fingers stroked her sore cunt almost gently now. "You did good," he said. "Next time I'm bringing friends." She shivered and pressed closer, already wet again at the thought.
He kept her there the rest of the night, using her mouth whenever he got hard, making her ride his cock while he slapped her ass and told her exactly what a free-use fucktoy she was. By morning she was sore, marked, and smiling like she'd finally found exactly what all those stories had promised.
