Steve has always considered Tony one of his best friends, and when Tony has a problem, Steve's always willing to help him out. He just never imagined that Tony would want his help in a situation like this one.
When Tony comes back from a very bad D/s date, in pain and abandoned by his dom, Steve offers to help Tony out and give him all the aftercare he so desperately needs.
Tony's a brat. It's just the truth. There's always that voice in his head that tells him to push, refuse, disobey. And that means no dom has the time or patience or skill to take him down into the subspace he craves.
“Hi, Cap,” he said, and his lips did the involuntary stretching towards his ears, because they didn't seem to be informed of the new ‘we do not act like a besotted school boy around Steve’ policy. In fact, none of the organs below his brain seemed to be on board with it. His heart was thudding, his palms were sweating and it was all Tony could do to stop his feet from moving past the fridge and straight into Steve’s personal space.
I wonder what he would think if he knew what kind of messages I'm exchanging with random people over the Internet.
He'd probably be horrified.

“JARVIS?” he said into the empty kitchen.
“Yes, Captain Rogers?”
Potential responses began to mass in his mind. JARVIS, I’m an idiot. JARVIS, this crush is getting out of hand. JARVIS, can you imagine any way, any possible way, Tony might be interested in me? JARVIS, some days I’m not sure if he even likes me. JARVIS, I think about him all the time. JARVIS, I’m ninety years old and I’m asking a computer program for advice on my love life. JARVIS, what should I do?
