I don't think Michael is getting naked (much as my mouth is salivating at the thought of it). I'm thinking a shirtless scene or something.
I also like how Peter and Jason's relationship seems "purer" because so little sex is shown; although there are sexual references shared between the two of them, their attraction seems to be governed solely by emotion. Jason and Ivy, on the other hand, go and do the nasty on Peter's desk (!!!) - with a hitched up dress, no less - giving it a tainted feel.
Still, I think the buttoning-up idea is cute and expresses the intimacy between the two of them without getting gratuitous.
