And there is a community for them : deanjamie.

I second After the Fade to Black (http://ficwriter1966.livejournal.com/205919.html) by ficwriter1966. One of the best fanfics out there, in my opinion.

Also, thanks for this search. There are far to few Dean/Jamie fics out there so it's nice to have a rec post of sorts :P

Man I serious second or third this rec! I've been meaning to ask, but just haven't lol

Someone needs to post all these over at deanjamie I'm the mod, so that's why I'm suggesting it! lol
