Seeing the emotion in Steve's eyes makes something swell in his chest. It's more happiness - it's love - and Tony hardly knows how to contain it all. Really, even if his ribs were collapsing, he'd probably still be smiling right now because being here with him like this is better than anything else in the world.

The sentiment is confirmed when Steve kisses his forehead, and Tony lets out a soft sigh that's just so damn content that it feels like he's floating. God, he thinks, Steve is spoiling him. He never used to be much for affection, but it's starting to dawn on him how much Steve has changed him already.

Pulling himself closer to him, he adjusts his position to kiss Steve's collarbone before tangling himself further against him and burying his face in the crook of his neck. Which he hopes that Steve doesn't mind - feeling him like this, skin to skin, feels like it's making his skin buzz with happiness, and he presses his lips softly against his neck after a moment.
