Hi!  I'm a long-time lurker, first time poster, so I hope I post correctly.  There are three specific wincest fics I read a long time ago, before I learned to bookmark.

1. The first one is a future!fic that has Michael from "Something Wicked" in it.  Here's what I remember about it:  I think Michael goes looking for Dean.  I remember that Michael is upset at first because Dean doesn't remember who he is.  It ends up with Dean, Sam, and Michael in a relationship.  Michael may have been a hunter in this fic?

2. This is another future!fic.  It has Michael and Lucas in it (from "Dead in the Water").  I think both Michael and Lucas go looking for Sam and Dean.  Sam and Dean train them to be hunters.  I think Michael and Lucas may also end up in a relationship together?  I think there was also something about Sam and Dean living in a particular area so they could sacrifice themselves when the time comes?

3. I don't really remember that much about this fic, but I remember liking it.  It was wincest.  Caleb was in it.  I remember there was a flashback at some point where The Winchesters were camping (I think) with Caleb.  Sam was a teenager.  He was masturbating and he had this kink for sucking on Dean's thumb and Caleb was watching him.  Also Sam had this huge crush on Caleb and eventually he ends up kissing him and Dean's watching from the hotel window and times it and is really jealous about it.
Does this sound familiar to anyone?

I'm also looking for any J2 recs that deal with the following (wincest is ok too):
1. I've seen a few fics where Jared has DID (or multiple personality disorder), are there any where Jensen has DID?
2. Any fic that deals with depression, addiction (drugs, alcohol, sex, etc.), or self-harm
3. Any college or high school fics

Thanks for your help!
