I think spazzy-looking Hank waving his hands and protesting "But, the space phantoms!" is my favorite part *grins* that, or Jarvis's deadpan "I'm sure master Tony will come as soon as humanly possible." And I love how Tony is naked or nearly so, while Steve is still in his uniform. Did Tony ask him to leave the mask on? *grins wider*

Anyway, perfect continuation. It could totally be canon!
(Tony: "I'm glad we worked things out" *thinks* because now we can have filthy sex in the monitor room
Steve: "So am I." *smirks a little as he thiks of filthy minotor-room sex, then blushes and looks away as he realizes that Tony is thinking of the same thing*)

The only question is, who initiated the sex that we all knew ensued, and that you've just so brilliantly showed us?
