It wasn't like he thought Steve was innocent, it was just -- it was what it was. He didn't have the brain capacity to reason things like these out right now, not when Steve had him falling into little pieces in zero to sixty seconds.
Sensation was a brand new thing right now -- when was the last time he'd even been with someone, let alone had something like this? Tony couldn't even properly remember, not really. Steve's beard was rough, his tongue soft, his fingers a firm presence. And then his words -- something gentle and entrancing and Tony couldn't, absolutely could not look Steve in the eye anymore lest he burst into poorly timed tears over it. "Gimme another," he said instead, head tilted toward the ceiling, back arched and his grip on Steve's hair a goddamned life line. "One more. C'mon."
