Ohgods. XD <3 I love it, it's just too precious and perfect. I especially love how Steve kept petting him, even though he'd changed back into a human. Obviously petting Tony while he's sprawled on Steve's chest is now a habit.

I have this wonderful image of Pepper finding the collar. That would go in the "handcuffed to the bed again" file, wouldn't it?

Congratulations. I'm hooked. I ship them.
