Hello everybody!

I am looking for Sam/Dean fic from about 2 (or maybe more) years ago. I read it a while back so I don't remember the title...or the author.
Here's what I recall though. Sam and Dean settle down at a house in a small town. Dean owns a garage and Sam is a professor. After an unlucky hunt (curse?) Dean has this weird thing where he cannot be touched by anyone but Sam, otherwise he becomes catatonic. I think, Sam tried to save him from the deal with crossroad demon and something went wrong, so both of them have matching scars.
The POV switches between Sam, Dean and a guy that works at Dean's garage and has a massive crush on him. He ends up finding out that they are lovers, and they are forced to leave the town.
Well yeah, that's pretty much it. I really hope someone read it and has it saved. That story was AMAZING!
I keep thinking it was from big bang challenge but I can't find it there =(

Thank y'all in advance!
