ellipsisblack has (had?) a really good verse called Another Soldier (on the road to nowhere) that had Michael deciding to become a hunter after meeting the boys. Years later he runs into Dean and decides to repay him by helping Dean find Sam who's gone missing after a hunt.

the rating was NC-17, the pairings where Sam/Dean, Dean/Michael and at one occasion Sam/Dean/Michael

thing is, I checked and her journal is friends only, but it's def worth asking her to friend you.

I dug around some and found her fic journal, conquest, and the 'verse master post. Looks long and awesome, thank you!! (http://conquest.livejournal.com/17820.html) ()

Full Tilt Boogie by hansbekhart & essenceofmeanin
Sam/Dean, Michael/Dean, Sam/Michael, Sam/Dean/Michael, Sam/OC, NC-17
Summary: There are only two kinds of secrets: the ones you keep, and the ones you shouldn't have at all. When Sam and Dean take Michel on his first hunt (that doesn't involve a shtriga), they end up on the psychedelic dance floor of a long-vanished motel where disco never died and no one is quite who they appear to be. What was supposed to be an easy salt and burn descends rapidly into a morass of temptation and gold lame, bell bottoms and lies. No one gets to choose what secrets stay buried.
Unless they don't mind checking in ... forever.
