This is a fic where Crowley is female, and it's kind of dark. There are mentions of rape/non-con, and explicit sexual scenes. That being said, it is a good fic, and I like it a lot.
Team Free Will teams up with Crowley, Gabe and Aziraphale
These are the only ones I have where Crowley is from both GO and SPN, but I have several more with two different Crowleys, if you're interested in those as well.

Aziraphale saves the Winchesters when they're in a spot of trouble, and gives them a message to relay to Crowley.
