I read a story a long time ago (more than a year) that was a game of thrones AU in which Jared and Jensen were new Crow recruits.  Further description under a cut.

I believe 1 of them (Jensen?) was a great fighter but was made a steward instead of a ranger because the leader wanted to keep him around to have sex with, even though Jensen didn't want to.  I think in the end they killed the guy who was giving Jensen problems, stole a couple horses, and escaped north of the wall.

I read this story before I watched Game of Thrones, but now that I've seen it I've been wanting to read the story again.  Help (or similar stories) would be greatly appreciated!
