He lay back on the sheets, shirt already gone, and I straddled his hips without wasting time. His nipples were already stiff from the cool air, small and dark against his chest. I grabbed both between my thumbs and forefingers and twisted them hard, no warm-up.
"Fuck," he grunted, hips jerking up against me. His cock pressed thick and hot through his jeans.
I kept twisting, pulling them outward until the skin stretched. "These things are sensitive, huh? Look how fast they get red." I pinched harder, rolling the nubs between my fingers until he hissed. His breathing turned ragged fast. I let go only to slap both nipples with my palms, then went right back to twisting.
He tried to grab my wrists but I knocked his hands away. "Keep them down or I stop." He obeyed, fists clenched at his sides. I leaned in and sucked one nipple into my mouth, teeth scraping, tongue flicking fast and rough. He moaned loud, the sound raw and needy. I bit down and pulled, stretching it, while my other hand worked the opposite nipple, pinching and tugging in rhythm.
His cock was leaking through his jeans now, a dark wet spot spreading. I ground down on it once, just enough to feel how hard he was, then focused back on his chest. I switched sides, sucking the other nipple deep, biting the base where it met his chest. He bucked under me, cursing.
"More," he begged, voice already wrecked. "Don't stop."
I laughed against his skin and bit harder. Then I reached for the clamps I'd left on the nightstand. Simple metal ones with screws. I opened one and clamped it onto his right nipple, tightening until he yelped. The left one got the same treatment. His chest heaved, nipples trapped and throbbing. I flicked both clamps with my fingers, watching them swing.
His cock jumped visibly. I unzipped him, pulled his dick out, and gave it one slow stroke. Precum smeared my palm. "You get this wet just from nipple play? Pathetic." I tightened the clamps another notch and stroked him faster, rough and direct.
He lasted maybe two minutes like that before he started begging to come. I didn't let him. I loosened the clamps just enough to remove them, then attacked his swollen nipples with my mouth again, sucking and biting until they were puffy and dark. His whole body shook. I jerked his cock in short, brutal strokes while I chewed on one nipple, then the other.
When he finally shot, it was loud and messy, cum splashing up his stomach and chest. Some landed on his own abused nipples. I rubbed it in with my fingers, smearing it over the sore nubs, pinching again through the mess.
He lay there panting, chest rising and falling fast. I didn't give him long to recover. I flipped him onto his stomach, pulled his ass up, and shoved two fingers in dry. While I opened him up I reached under and found his nipples again, pinching from behind, twisting them while I worked his hole.
By the time I pushed my cock in, he was hard again. Every thrust made his chest drag against the sheets, rubbing his raw nipples. I reached around, grabbed both, and used them like handles, yanking him back onto my dick. He came again without touching his cock, shooting onto the bed while I kept twisting.
After I filled him, I pulled out and rolled him over. His nipples were bright red, swollen, and slick. I sucked them one last time, gentler now but still firm, until he whimpered from overstimulation. Then I lay beside him, one hand resting on his chest, occasionally giving a lazy pinch just to watch him twitch.
He didn't move for a long time. When he finally spoke, his voice was hoarse. "Next time, use the clamps longer."
I smiled against his shoulder and gave one nipple a final hard twist. "Count on it."
