The nuzzling is reminiscent to Tony of some overly excited golden lab trying to get attention. It works quite well, causing calloused hands to drop from his fly before he gives in to Steve’s insistence. Giving up authority by directing the shift in power is really Tony’s cup of tea. He builds his machines, he creates his software, to mimic that role for him, willing to do whatever he wants while seeming like they have minds if their own outside of what he created for them. They don’t. JARVIS doesn’t count, since it had been the Mind Stone that gave him the authority that he had not had before, combined with Bruce and Ultron and Tony himself.

The inventor closes his eyes and lets his head fall against the wall. Contrary to popular belief, it is possible to give bad head, but Steve is no where near bad.

And Tony has received many, many blowjobs in his life.

This one takes the case in terms of bliss and he has to do complex calculations to begin to stave off an early and unwelcome ejaculation. Anymore, he’s much too sensitive for multiple rounds that he had enjoyed in his youth. He knows how to stave his pleasure off, usually— Steve’s mouth, velvet and wet, has his stomach in knots mere minutes after his performance starts.

So Tony has to stop him. He has to or they’ll never get to the bedroom, never take the technicality away from Steve— Tony doesn’t want that.

“Oh-okay—“ he finds himself whimpering, like some teenager, and the moment Steve has him out of his mouth, he’s trying to yank him up. “Bed...?” His legs still function, even with a rock hard erection and pants around his knees.
