Oh wow, Steve just goes for it, and it's amazing, and a good reminder to Sean that right, right, a lack of experience isn't the same thing as wanting to go slow or be shy. When Steve wants to go deeper, he happily goes deeper, parting his mouth to invite Steve's tongue right inside. There's a hand on the back of his head and it's nice, and Sean goes ahead and set his free hand on Steve's waistt, fingers sliding against that warm, tight t-shirt and the impressive body beneath.

He does his best to make the kiss good for them both, a little wet and a little dirty now that Steve's opened the door. God, he's making out with Steve Rogers in the Avengers Tower elevator. The world is wild.

And soon as he hears the doors open, the hand on Steve's side slides down, fingers hooking on the waistband of those tight jeans and tugging Steve forward as Sean walks out of the elevator backwards, still kissing him.
