Looking for a Fic

I wrote someone (I cannot remember who) comment porn sometime over the summer. It was SPN wincest, outside pov (Mara, their lawyer, in Folsom Prison Blues). Mara was talking to Hendricksen's partner and the partner is all, yeah, they're incestuous serial killers.

Does anyone know where this is, since I can only remember writing it, not who I wrote it for?

I kind of want it for my SPN/AG crossover for Samantha Black Crow to... ahh, I just need it. Help? I know it was someone on my flist.

ETA: almostinstinct, for some reason, I think I wrote this for you?
