Tony/Steve fic

[elleian.livejournal.com]

I'm looking for a specific fic which has a scene with Logan in it, so I am assuming it is an older fic/not MCU. I'm pretty sure it features the fantastic four and x-men, at least in passing. Tony and Steve's relationship isn't public knowledge for most of the fic. There is a scene after a battle where Logan tells Tony that he can’t work out which one of him or Steve is the cradle-snatcher, and Tony tries to deny that they have a relationship, but Logan says he can smell Steve all over him. And I think there are other bits about Steve having a bruise in the shape of the arc reactor on his back. I hope someone knows which fic this is!

Found, it's Semaphore by DevilDoll.
