He hadn't realized that he'd been working himself up so much until Steve snapped him out of it, voice firm and grip almost painful. But in a good way, sort of. Like the arm around him before. It was just.
Grounding.
Enough that he could wipe at his eyes with his palm and then take in a deep breath, slow this time because he knew better. Or should have anyway. "Yeah," he said, but it was slightly dismissive because Tony didn't want to plan his life on you never knows, he didn't want to drive himself crazy hoping for something that might never come.
Especially not when something else he'd spent years hoping for was right in front of him. Steve, looking so earnest and worried all at the same time, like there was so much riding on Tony's answer. Maybe there was. Or, there could be. There was a lot here that could be, and they'd been catching glimpses of it for nearly three months now. There was no denying his own interest, even when his heart hurt for something else right now. But it was something different, that could not be compared or measured in the same way.
Tony was a lot of things, but he wasn't ever someone who offered things in halves. "Fuck you, Rogers," he said quietly. His decision was made even as he shifted, twisting enough on the bed so that he was properly facing Steve and pulling him in for a kiss that was more a smashing of mouths than anything taking expertise.
