I know there are a couple of stories with this theme.

What I know: In one Jensen is at a house party and runs into the guy who 'discovered' him. JDM and Christian Kane (I think Dave Boreanaz might be involved somehow, as a good guy) know this guy is bad news; they get him to admit he drugged and assaulted Jensen.

In another I think Jared's dad convinced him to go with a particular agent/manager (with the knowledge that he wasn't a good guy). The agent basically gets Jared shit jobs and expects sexual favors in return. He's convinced Jared that he's not a good actor.

I'm not sure about pairings (except for non-con Jensen/OMC). I think they might both end up Jensen/Jared
If you good people know of any other fic along similar lines I'd love to read them, too.

Edit: Second fic found. It's Mis-Managed (link in comments).
