The plot goes that Kurt and Blaine are married in the future, and I believe Kurt is working as either a recording artist or an actor in a musical. Blaine is definitely doing some sort of stage performing. The story starts out with Blaine's director coming on to Kurt and Kurt having to fend him off a bit. After a while, the director threatens to fire Blaine if Kurt doesn't sleep with him so Kurt gives in. Kurt has sex with the director but afterwards, the director continues to blackmail him into more and more sex. I know that Kurt ends up physically abused but that nobody notices because he's able to cover it up pretty well. I remember that Blaine walks in on Kurt and his director while they're in the act and thinks that Kurt's cheating on him (I think he throws his wedding band, it's all very angsty and dramatic) and threatens him with divorce. In the end, a colleague of Kurt's who knows what the director has been doing to Kurt tells Blaine what happened and Blaine finds Kurt and helps him to recover. I know the directors goes to jail, with Karofsky as his prison guard as a little twist at the very end.
I remember this fic so well and I desperately want to read it again but I can't find it for the life of me, any help would be much appreciated.
Also, I know it was on fanfiction.net, if that is any help at all.
Thank you in advance.
