Specific fic search

[http://users.livejournal.com/_thelostcity/]

Hi all, I'm looking for a specific fic. Unfortunately, I don't remember much other than it was Steve/Tony, they were in Tony's workshop, and while the two of them were talking to other team members who came down, Tony ran his fingers up and down Steve's spine, causing Steve to stand up straight. There may have been something about Tony liking it when Steve stood up straight-and-tall? I might be misremembering that part, though.

Thank you!
