Steve wasn't just used to it, he loved it. However Tony came to him, however he was, that was what Steve wanted. He was gorgeous and every scar or bump of his ribs was something that he wanted to cherish. He shrugged off his own shirt as well so at least when he put Tony back down on his feet their bare stomachs were pressed together, that point of contact.
They'd been together for a little while, but it had been a little bit unsure and Steve knew that was because of what he'd done. It hadn't been the ideal place to start, but Tony had stuck by him and in that kiss, that heat Steve knew it was okay now. The other man had died and they might go back there, Steve could lose him in so many different ways and he couldn't let that fear stop them from having something now.
Steve groaned into his mouth, it wasn't the first time he'd felt desired but it was the first time he'd ever felt so close to another person. Tony knew everything, all of his secrets and he wanted him anyway and there was something incredibly intimate about that. He moved backwards blindly, glad there wasn't much between them and the bed made neatly against the wall.
