She knelt on the cold stone floor exactly as instructed, knees spread wide, palms upturned on her thighs. The collar around her throat was already locked, the small steel ring at its center catching the low light. He circled her once, boots echoing in the soundproofed room, then stopped behind her and fisted her hair, yanking her head back until her throat stretched taut.
“Tonight you give everything,” he said, voice low and absolute. “No safeword will stop me unless you use it. Nod if you understand.”
She nodded, pulse hammering against the leather. He released her hair and walked to the table where the implements waited. Leather cuffs, a heavy flogger, a length of chain, a thick silicone plug already slicked with lube. He chose the cuffs first, buckling them around her wrists and clipping them together behind her back. The position forced her shoulders open, breasts thrust forward. He attached the chain to her collar ring and ran it down between her legs, threading it through the cuffs so any movement tugged the metal against her slick folds.
“Stand.”
She rose unsteadily. The chain pulled tighter with every shift of her hips. He led her to the padded bench and bent her over it, securing her ankles to the legs so she was spread and helpless. The first strike of the flogger landed across her ass with a heavy thud. Heat bloomed. She gasped.

He did not pause; the next blow crossed the first, then another, building a lattice of fire that sank deeper with every impact. She began to rock, the chain rubbing her clit with each involuntary jerk.
He set the flogger aside and pressed two fingers inside her without warning, curling hard against her front wall. “You’re dripping. You want the pain because it makes you honest.” He added a third finger, stretching her, then withdrew and replaced them with the plug. It slid in with a slow, burning fullness that made her thighs shake. Once seated, he locked a small padlock through the base so she could not push it out.
The chain was rerouted so it ran directly over her swollen clit. Every breath now tugged it. He freed her wrists only long enough to cuff them in front of her, then clipped them to the bench so she was folded and completely open. She heard the rasp of his zipper. The blunt head of his cock pressed against her entrance, stretching her around the plug already inside.
He pushed in slowly, letting her feel every inch as he filled both holes. When he was seated to the hilt he gripped her hips and began to thrust, each stroke driving the chain tighter against her clit. The rhythm was deliberate, almost cruel, designed to keep her on the edge without release. She begged, voice hoarse, but he only answered with harder strokes and a sharp slap to her already burning ass.
“Ask properly,” he growled.
“Please, Sir. Let me come.”
He reached beneath her and pinched her clit hard between two fingers, holding the pressure while he fucked her. The orgasm tore through her in violent waves, her body clamping around both intrusions. He did not stop. He rode her through it, through the oversensitivity, until she was sobbing and another climax built anyway. Only when her legs gave out did he pull free, remove the plug, and finish across her reddened skin.
Afterward he unbuckled the cuffs, wiped her clean with a warm cloth, and drew her into his lap on the bench. His hand stroked her hair in steady, grounding circles while her breathing slowed. She pressed her face to his chest, tasting salt and leather, and felt the collar still locked around her throat. The power exchange had left her emptied and remade, exactly as he had promised.
