She dropped to her knees the second the door locked. The cuffs bit into her wrists behind her back, cold metal already warming from her skin. He stood over her in boots and nothing else, cock half-hard and thick, swinging heavy as he circled her.
"Open your mouth, slut." His voice came out low and rough, no warm-up bullshit.
She did. He shoved two fingers past her lips, pressing down on her tongue until spit ran down her chin. "Good. Keep it wet. You're getting the full treatment tonight."
He pulled his fingers out and replaced them with his cock, shoving it straight to the back of her throat in one thrust. She gagged, eyes watering, but he held her head and fucked her face anyway, balls slapping her chin with every stroke. Saliva poured down her tits. He pulled out only to slap her cheek with his wet dick, then drove back in harder.
When he was done using her mouth, he hauled her up by the hair and bent her over the padded bench. Leather straps went around her thighs and upper arms, locking her down tight, ass up, legs spread wide. Her pussy was already dripping down her thighs. He noticed.
"Look at this greedy cunt." Two fingers shoved inside without warning, pumping fast. "Soaking wet and I haven't even hit you yet."
The first strike from the crop landed across both ass cheeks. She jerked in the restraints.

He didn't pause, laying down ten hard strokes in a row, each one sharper than the last. Her skin bloomed red. She moaned through clenched teeth, cunt clenching around nothing.
He switched to the flogger next, heavy leather tails thudding across her back and ass. Every few hits he reached between her legs and rubbed her clit in tight circles, keeping her right on the edge. When she started begging, he stopped touching her altogether.
"Please," she gasped. "Fuck me. Use me."
He laughed once, dark. "Not yet."
The plug came next. He worked it into her ass with spit and slow pressure until it popped past the ring and seated deep. She whined at the stretch. He left it there while he caned the backs of her thighs, thin lines of fire that made her shake.
Only when her ass and thighs were marked red did he step between her spread legs. He yanked the plug out, lined his cock up with her pussy, and drove in balls-deep in one brutal thrust. She screamed. He didn't give her time to adjust, just started pounding, hips slamming against her sore ass, the bench creaking under the force.
He fucked her like he owned her, one hand gripping her hair, the other reaching under to pinch her clit hard. Every time she got close he pulled out, waited, then slammed back in. Her juices ran down his balls. The room smelled like sex and leather.
After the third time he edged her, he pulled out and walked around to her head. He fed his cock back into her mouth, making her taste herself while he fingered her ass open again. Two fingers, then three, stretching her while she sucked.
When he finally untied her thighs and flipped her onto her back, strapping her down again with legs spread wide, she was shaking. He pushed her knees toward her chest and sank his cock into her ass in one slow, relentless push. She took it, panting, eyes rolling back.
He fucked her ass hard, deep strokes that made her whole body jolt against the straps. His thumb worked her clit the whole time. "Come on this cock," he ordered. "Now."
She came with a hoarse shout, ass clenching around him, pussy pulsing and squirting a little. He kept going, using her through it, until he pulled out and painted her tits and stomach with thick ropes of cum.
He left her strapped down a few minutes longer, cum cooling on her skin, while he stroked her hair and told her she was a good fucktoy. When he finally released the cuffs, she stayed on the bench, breathing hard, body marked and used exactly the way she needed.
He helped her up, steadying her when her legs wobbled. "Shower. Then bed. We're doing this again in the morning."
She smiled, raw and satisfied. "Yes, Sir."
