K/S, reboot, Spock thinks Kirk's cheating... (he's just jerking off in jefferies tube)

This has been driving me crazy!
K/S, reboot (pre-stid). I think they're in an established relationship and I think Spock is impotent outside of pon farr?
What I do remember is that they were bonded and Spock feels Kirk's guilt and that he's doing something sexual. Spock assumes he's cheating and tries to be all logical that it was expected. Kirk is in a jefferies tube maturbating... He'd been refraining for a while but couldn't hold back anymore... He assumed that Spock would find it distasteful or something... Of course happy ending :)
I know you awesome peeps will be able to identify it right away!! I feel like it's some well known writer.
Thank you so much in advance!
P.S. If you haven't read it, you should :)

Flagship Enterprize

[that-carlygirl.livejournal.com]

Okay, so this was a reboot fic. I don't remember much, just that they ended up in a situation with a lot of Federation ships, and Kirk was actually the highest ranked officer? I think one part focused on hoe the Enterprize is the flagship of the fleet, with the best and brightest on board. Or I might be mixing up two fics.

Any other fics along these lines are welcome as well!

Thanks!
