Hey, anything was a fetish if you tried hard enough. But Enthusiastic Consent was more like ... what the general policy should have been. Still, there was something sexy about the fact that Steve liked doing it up in layers. Sex in general and then whatever else he wanted to be doing at the time. Tony could get behind it, so, so much.
Anyway, Tony knew it was safe. It wasn't like he hadn't considered it before. It'd just ... never come up before now. Oddly.
And no. No he was not ready. They both knew that. But he was close enough. He wanted that slight burn and stretch as much as Steve probably wanted to feel the way it took a little extra effort to push in, the hot and tight of him. Tony actually shivered in want over Steve's question, exhaled deep. "Kiss me, first," he said, straightening his back a little and looking over his shoulder at Steve.
