LF Wincest bottom!Sam, Samifer fic

[iotajot]

I read this fic years ago. In it Sam has said yes to Lucifer and basically laid waste to everything. Dean figures out how to exorcise Lucifer and it’s some kind of spell during which wincest happens. I know there’s a scene where he pins Sams hands to the ground with knives. True Sam is in and out during this so it’s kinda dubious consent.

I’ve had no luck finding it on my own so any help is appreciated.
