Fics where Ilya claims seniority

Sometimes I think about the length of Shane and Ilya's relationship.

They met at 17, hooked up at 19, became exclusive at 26, married at 30. That's 13 years of history and almost half of their lives.

Is there a fic where Ilya basically plays the seniority card? Like, "I was here first" or "I've known him longer than you, Pike"?

I've read a bunch of fics where people are shocked when it's revealed they've been together since they were rookies, but none where Ilya's kind of rubbed it in.
