I'm looking for a short ficlet that I think was on tumblr, set during WWII, from Howard Stark's perspective. He was watching Bucky, who he had a crush on/found attractive although he was trying to be subtle about it, only either Bucky himself or one of the Howlies (possibly Dugan?) tells him he should be careful because Bucky's a taken man & the Captain doesn't share and he looks up/across where they're stood to see Steve smirking at him possessively.
Sound familiar to anyone?
Edit 10/2/17: My tired brain was thinking of
this post, and got the details muddled. I apologise for this mess of a post. >_
