With the way Tony is riling him up, pushing him closer to break apart its impossible to properly quell down the sounds that are coming from his throat. Bruce cries and moans and arches into Tony's hands and mouth and cock, reaching up towards the peak.

He hears Tony correcting him, and its like flicking a switch - Bruce squeezes his eyes shut as he repeats the correction, chanting it mindlessly like a mantra he wants to remember. "Tony. Tony, Tony--please, Tony, I can't, Tony--"

Bruce continues to utter Tony's name like a prayer, almost babbling incoherently up until Tony marks him on his throat. A shot of pure lust rides up within him and Bruce chokes on it, his entire body freezing for a moment before everything falls apart. Bruce lets out a half-choked sob as he comes harder than he had ever remembered himself coming, spilling over Tony's hand as he shudders violently through his orgasam.
