She stood naked in the middle of the bedroom, tits already hard from the cool air and the way he stared at them. He held the clamps in one hand, silver and mean with little teeth that bit down hard. "You wanted this," he said, voice flat and direct. "Say it."
"I want the clamps," she answered, spreading her legs a little so he could see how wet her pussy already was. "Put them on my nipples and fuck me while they hurt."
He grabbed her left tit first, squeezing the flesh until the nipple stood out stiff and dark. He opened the clamp and let it snap shut right on the sensitive bud. The pain hit sharp and immediate, a hot sting that made her gasp and arch her back. He didn't wait. The second clamp went on the right nipple just as fast, teeth digging in deep. She moaned, the sound low and dirty, because the ache was already spreading down to her cunt.
"Walk around," he ordered. "Let me see how they pull."
She took a few steps, and every movement made the clamps tug on her nipples. The chain between them swung and added extra weight. Her tits bounced slightly, and the pain flared hotter with each step. She could feel her pussy dripping down her inner thighs. He watched her like he was studying a toy, cock already thick and pushing against his jeans.
"Hands behind your back," he said. She obeyed, and he clipped the chain to a short leather strap around her waist so her clamped nipples stayed pulled forward. The position forced her chest out, nipples stretched and throbbing. He unzipped and pulled his cock out, thick and veined. "Kneel and suck it while those clamps do their job."
She dropped to her knees. The sudden drop jerked the clamps harder, sending fresh spikes of pain through both nipples. She opened her mouth and took his cock deep, sucking hard and sloppy. Spit ran down her chin as she worked him. Every bob of her head made her tits sway, and the clamps bit deeper. She moaned around his shaft, the vibration making him grunt.
He pulled out after a minute, strings of saliva connecting her lips to his cockhead. "On the bed. Face down, ass up."
She climbed onto the mattress, the clamps still chained and tugging mercilessly. Her nipples felt swollen and burning. He climbed behind her, spread her ass cheeks, and slammed his cock straight into her soaked pussy in one thrust. She cried out, the force rocking her forward and yanking on the clamps again. He fucked her hard and fast, no buildup, just deep strokes that slapped his balls against her clit.
"Reach back and pull on the chain," he told her. She did it, fingers wrapping around the metal link and giving a steady tug. The pain exploded sharper, her nipples stretched and crushed at the same time. Her pussy clenched around his cock like a fist. He slapped her ass once, twice, then grabbed her hips and pounded harder.
She came first, a rough orgasm that made her whole body shake. The clamps hurt so much during the climax that it blurred into something hotter. He didn't stop. He kept driving into her, using her cunt while the pain kept her nipples screaming. When he was close he reached under her, grabbed the chain, and yanked it hard enough to lift her tits off the bed. The sudden brutal pull sent her over again, screaming into the sheets as her pussy spasmed around him.
He pulled out at the last second, shot thick ropes of cum across her lower back and ass, then unclipped the chain from her waist but left the clamps on. "Leave them," he said. "We're not done."
She stayed on the bed, nipples still trapped and aching, cum cooling on her skin, already knowing round two would be even rougher. Her body felt used exactly the way she needed, every throb from her clamped tits feeding straight down to her still-hungry cunt.
