The 'Who bottoms' guy

I'm looking for a fic where Steve and Tony had recently gone public with their relationship and the only scene I remember is:

Steve comes in all huffy puffy because of the press being all up in their business and Tony is like "oh did the 'who bottoms' guy get you?" And Steve is like wtf are you talking about and Tony is like "you know, that one dude who jumps out of bushes and is like 'who bottoms?!'" and then Tony says he's impressed by the dude's commitment that he's almost tempted to answer and Steve gives a huffy puffy "Tony!" And Tony's basically like calm your tits I said "almost"

That interaction is vivid in my mind lol but I can't remember the fic.
