Bruce feels Tony wriggling around beneath him, the removal of pants- oh. He swallows hard, assuming what Tony means by 'touch me'. Each kiss is electric, making his breath shudder and throw him more off-balance, but he knows he can't let himself go beyond this point. Things have to stay safe, for Tony's sake.

But maybe he could just pleasure Tony instead. That... Would be acceptable. He's ignored himself for years enough that his body hasn't reacted terribly much yet, though he could feel Tony hard through his soft sleeping pants.

Cautiously, a hand slides down and just like that, thinking it is a start on a path he's firmly lost sight of, he cups Tony in his warm palm, feeling the nearly matching heat.
