Well, everyone knew that a shirtless Steve was an absolute wonder, and there was no time when Tony wouldn't approve of it -- not that either of them were backing away from each other for long enough for him to get a really good look anyway. The knowledge was enough, and being pressed up against each other was better. A tell tale sign of the both of them being alive.
Steve went backwards and Tony went forwards and it was only blind trust that had him stepping wherever Steve lead, kissing thoroughly instead of worry about where they were going or if there was anything to trip over to send them both tumbling down.
Luckily there'd been no reason to worry at all because when Steve's knees hit the back of the bed they both stopped, Tony's momentum only making him wobble a little, his balance kept by Steve's arms around him and the balls of his own feet. Taking a breath felt unacceptable and paramount at the same time, and Tony rocked back a little to do so even though he didn't want to, inhaling and letting his eyes go up to Steve's face. "I'm here," he repeated, because it was -- even with solid reminders, maybe they both just needed that reassurance right now. "Steve."
