Looking for specific demon Sam and Dean fic

[angelzfurys.livejournal.com]

I swear I had this one great demon Sam and Dean fic bookmarked but turns out I guess I didn't or it got erased so I need help finding it again. I believe is was on ff.net and I have looked all over but can't find it.

Sam and Dean are demons in hell and angels go to hell regularly to find mates and take the back to heaven. Lucifer and Michael fight their way into hell and Lucifer knows that Sam is his mate but Michael is just drawn to Dean so Lucifer and Michael kidnap Sam and Dean and return to heaven. Sam and Dean are kept seperate in rooms for Lucifer and Michael who must tame them to fully mate with them. Lucifer and Sam hit it off and do well, Dean hates Michael and fights him constantly and Michael takes joy in beating Dean. Castiel is a soldier in heaven who works for Michael and cleans up the room and Dean after Michael is done with him. Dean and Cas fall for each othr, and I think in the end Sam and Lucifer help Cas win Dean from Micheal.

Does this sound familiar to anyone? If someone knows what fic this is could you please point me in the right direction, thank you.

I hope I got the tags right, I went a little overboard just to be safe

I remember reading this fic, but it was Gabriel instead of Lucifer. Every single other detail matches perfectly. I know it's somewhere on AO3.

So I think I found it:
Castiel/Dean Winchester Gabriel/Sam Winchester Michael/Dean Winchester

Summary: "After watching humans find love in the oddest places, angels have decided to look to hell to find their soulmates. When Michael finds Dean, he decides to claim him as his own. Dean has other ideas, especially when he meets an angel named Castiel. Michael is not amused, and will do everything in his power to keep them from each other."
