The pleasure starts to build quickly now that Tony is hitting his prostate properly, and Bruce lets out a gasp as his free hand claws at the bedsheets, trying to anchor himself even as the remmants of his control fracture and break. It only gets worse when Tony starts to stroke his erection once again, and Bruce moans lowly, shivering at Tony's words.

"You're--" he tries to respond, but his words are quickly replaced with another moan. Tony is relentless in giving him pleasure now, and there's so much to take in he can't even make heads of tails of what to feel. All he knows is pleasure and Tony who is giving him that pleasure. Tony, who feels far too good inside of him and the thought of that gets another moan out from Bruce.

It doesn't take long from there for Bruce to lose himself. Soon the only thing that's coming out from Bruce's mouth are a stream of wordless cries and half-formed moans because he can't even concentrate enough to properly let one out. His eyes fall shut of their own accord as he feels the beginnings of his orgasm starting to approach.

He whines at a particularly well-aimed thrust, arching upwards as the words leave him in a punctured gasp. "I can't--Tony," he begs mindlessly - babbles, really, because he can't think hard enough to know what he's saying. "I can't anymore. Please--" He pauses to let out a incoherent sound, and his thighs tremble. "--please, please don't stop. Tony, please."

Anymore of this and he's going to come. He's going to break apart and fall and shatter into a million pieces and it'll be so, so good.
