Hey everyone, I'm looking for 1.) AU-fics with Dean and Sam unrelated in which Dean is either a demon or a vampire and meets Sam; they end up together. Something like -In Arcadia Ego- and -Fortress- by the same author (I know they are still considered related in Fortress). Preferably long fics, but I'll take what I can get. I would really like it to be top!Dean, please warn me if it's not. Also I'm okay if Dean is some other kind of creature as long as he is strong or has powers or is plainly superior to Sam on some level.

And 2.) much like Fortress I'm yearning for a long-term fuck-or-die curse with top!Dean and bottom!Sam. Doesn't matter who's inflicted by the curse, I reckon they aren't even that many fics with this request. I thought I'd ask the shared brain pool of the spnfamily; if anybody knows, it's you guys. Basically I'd like either one of the brothers to be cursed and end up having sex with the other, but it's not supposed to be a one-time thing. They have to keep on appeasing the curse otherwise they die (or the one who's cursed at least).

Please no Destiel in any recs...
Self-recs welcome.

Thanks in advance!
