Leaving bite and bruise marks on Steve never really felt like an effort in futility on Tony's part even if they did fade so quickly. It wasn't like he didn't have fun putting them there in the first place. Sometimes he liked playing a game about what kind of noises he could get out of Steve when he used only his mouth.
It was a fun game. There was no score, but Tony was definitely winning.
Just like he was winning right now, for completely different reasons.
It -- Steve -- felt good. Different, a little. Like there was just a little more, like the friction was just changed enough where he noticed if he put his attention to it. Which was, admittedly, getting harder to do by the second. Coherency and attention to detail were coming in at a slow second and third (and probably not even in that order) on Tony's list.
Honestly. Only Steve Roger's could fuck Tony stupid.
He let out a noise that was practically a sob when Steve thumbed at his rim, because it wasn't what he'd asked for (demanded) and he was overwhelmed with the way that Steve was fucking him already, but it also felt good.
