Justin cheats several times on Brian. (found)

[leiram81.livejournal.com]

Hi everyone, I'm looking for a fic (obviously) in which Brian and Justin are together, but are not monogamus, so Justin "cheats" as in he gets involved with other men and leave Brian to be with them, pretty much like the whole Ethan thing,and of course after a while he goes back to Brian. Brian confronts him because this hurts him so he asks Justin if he's done with his guys and Justin asks him if he is done with his tricks, Brian says no and Justin says something like this: "so you keep your guys and I'll keep mine and we'll keep doing this because neither of us is strong enough to walk away from this"
it was a oneshot and was pretty angsty too.

I know it sounds weird, but if anyone knows wich fic I'm talking about, I'd be very grateful.

fic is Mercy by crazyevildru, link in comments.
