1. I'm looking for a specific Dean/Cas fic that I read about two or three weeks ago (although it could easily be an older fic that I only happened to stumble upon recently), pretty PWP, and from what I remember it was about how angels claim a mate on the night before a battle (and Cas claimed Dean obviously). I also remember that Cas was wearing some special battle attire that Dean was very distracted by.

2. I'm wondering if there are any Dean/Cas, Dean/Sam, or Dean/Cas/Sam fics that address Dean's "re-hymenation" after he was brought back from hell. Like instead of looking to that beer wench to lose his virginity again he goes to Sam and/or Cas.

3. I'm also wondering if there are any Dean/Cas AU fics where Cas meets Dean before he goes to hell (and ideally where Dean is not sent to hell at all) and Dean and Sam are still hunters.

4. I'm also looking for any Dean/Sam fics that address Dean's feelings of betrayal after coming back from hell and finding out about what Sam and Ruby have been up to (specifically the blood and exorcism thing, it doesn't matter if it includes the sex thing or not) and how Sam lied about it. Ideally it would have Sam regaining Dean's trust and not a sad ending.

5. Also, does anyone know of any AU Dean/Cas fics where Mary and John aren't dead, or if they are dead, Sam and Dean aren't hunters (and Mary wasn't killed by Azazel) and Cas is ideally human (although being an angel wouldn't be a deal breaker at all). I kind of have "What Is and What Never Should Be" in mind minus the djinn and the alternate reality angle. I don't know if there are any fics like this but I'm looking mainly for ones that include Dean and Cas meeting although if it fits the other requirements but they already know each other then that's fine too.

ETA: First request found by anonymous although I'd still love any recs for the other four requests: Taking a Mate by by_starkiller
