The thing was Steve was just really, really into Tony. That meant liking when he talked, liking shutting him up, liking hearing the words from his mouth and liking making him speechless. Steve was into everything as long as it was Tony, so far anyway, things just seemed to get better and better.
Sure things were hard and they'd been through a lot in their relatively short relationship, the sex had been effortless and only seemed to get more enjoyable the closer they got. He loved that Tony asked for what he wanted, Steve didn't have to guess and judging by his reactions this was just what he needed.
Only Tony could call him something like 'cupcake' and not ruin the moment. He laughed as he leaned over him kissing his shoulder before he sucked a bruise into the skin there. He had to push his fingers into him, a little rough and that was what they both needed in that moment. Inside Steve curled his fingers, rubbing against his prostate because it wasn't just about getting him stretched it was about getting him to see stars. "They look really good in you."
