Blind Faith (http://archiveofourown.org/works/102759) by Adrenalineshots

Steps Behind (https://www.fanfiction.net/s/4800435/1/Steps-Behind) by Mirrordance

http://archiveofourown.org/works/228962/chapters/347430 (http://archiveofourown.org/works/228962/chapters/347430) A J2 fic that has both humor and angst.

http://archiveofourown.org/works/4974685 (http://archiveofourown.org/works/4974685) It's short, but angsty. Jared's a bit of a dick, though.

http://archiveofourown.org/works/5325467 (http://archiveofourown.org/works/5325467) Wasn't sure whether to put this one, but put it just in case. It'd basically J2 reincarnation and ends when they're at the SPN jobs.

If you've searched for wincestiel you've probably found these, but:

This one is AU, but: CollegeAngels.com (http://archiveofourown.org/works/596270)
AU. Dean and Sam have always been a little too close, and Dean knows it's wrong -- so he heads to college, hoping that he'll meet someone there who will keep his mind off his little brother. He meets Castiel, who has a business proposal for him --- join Cas in bed, and online, for live webcam site CollegeAngels.com. Through Castiel, Dean learns about sex, kink, and freedom, and he finally feels pride instead of shame for who he is. But then Sam gets accepted to the same school, and he wants to live with Dean...

The Three Bosy Problem (http://archiveofourown.org/works/2787743)
Cas asks the Winchesters on a date. Yes, both of them.


Again, an AU: Radius of Convergence (http://archiveofourown.org/works/1597055) It's really short - this'll take 10-20 minutes to read at most, and is well worth.
Maybe some faulty part of Sam’s brain had crossed up the various definitions of love when it came to Dean, but he couldn’t bring himself to regret it. Filial love, friendly love, and romantic love had all been melted down and poured into the mold of Love for Dean.
Cas’ smile was soft and kind and made Sam think he understood a little too well why Sam was sitting on the back steps staring up at the stars.
Or, in which Cas really just wants the Winchesters to quit angsting and embrace polyamory.


Apologies and Other Disasters (http://archiveofourown.org/works/1033814)
Canon divergent AU from 9.03. After Sam kicks Ezekiel to the curb, the first thing they do is to go find Cas.


This isn't wincestiel, but is destiel that is... complicted: Our Bodies, Possessed By Light (http://archiveofourown.org/works/260289)
Purged of all his souls, Castiel is a changed being, stronger than an angel and too powerful for Jimmy's body to contain. Happily, there's an archangel's vessel on hand, and he could use fixing, too. Dean isn't too happy about the idea of his brother acting as a vessel for Castiel, and Sam can guess why, but it isn't until Castiel gets inside his head and they learn to share the vessel -- and their thoughts -- that Sam realises Cas is as in love with Dean as Dean is with him. It's unfortunate that there's nothing much to be done about it now, but Castiel will get another vessel soon. The Winchesters will make damn sure of that. In the meantime, it's up to the three of them to establish their own strange accord, and Dean realises more fully than ever that it's Castiel, and not his vessel, that he loves.

As far as epic length destiels go, I only know of AU's, like Out of the Deep (480000 words), Angel's Wild (390000 words), A Little Patience (290000 words), Into Your Hideaway (170000 words) and Morning Teach (170000 words)

If you're interested, Misha's Not in Vancouver Anymore (http://archiveofourown.org/works/1399918) , which is a weird mash up of Misha/Dean/Cas and at the very end a little of Jensen. An accident on set results in Misha ending up in the SPN!Verse and stuck with a confused and irritated Dean Winchester. Dean, Sam, and Castiel have to work together to find a way to send him back. Misha's cheekiness brings to light the things that Dean only ever thinks about in the space between waking and dreaming.

And, of course, Revenge of the Subtext (http://archiveofourown.org/works/4856132) (Destiel with Cockles as a sprinkle on top) and The Plot (http://archiveofourown.org/works/2795588) (Cockles)


This is a J2 AU, but I'm of the opinion that it's hilarious and that everyone who's not read it is missing out, so... Killer Romance - The Complete Series (http://archiveofourown.org/works/914241) It is dark humour, tho, Jared's a mob boss, and Jensen is an "ex" assassin.

Thats all I can find going through my bookmarks, soo I hope this is what you're after :) enjoy
