I'm looking for a fic I read some time ago, where Steve and Tony are in a relationship and it turns out that Tony is gradually losing some of his obvious ageing (wrinkles etc) due to prolonged exposure to Steves super soldier serum - from sexual contact.
This wasn't the point of the story as I recall, more of a minor story arc within a bigger story. I seem to remember it was a longish fic, and that maybe Tony was running Shield in it at some point. Not sure about that last bit though, I could have confused it with a different story.
Not much to go on I know, but I'd love to re-read it, does it ring any bells with anyone?
Fingers crossed someone out there knows it!
