If Aziraphale wants to get monster fucked, who's Crowley to deny him? Play with him, hunt him, scare him to death. You're the predator.

Fallen Angel, Serpent of Eden. Husband-idiot Made for smut with Aziraphale!

Aziraphale visits the Victorian ball as a lady. He has a task, but with a cheeky demon circling him and determined to show Aziraphale how to enjoy the night the chance to be productive comes to zero. The prompt is heavily based on "Time Flies (When You're Having Fun)" by Mussimm (https://archiveofourown.org/works/24794503). Read it and show appreciation! You may or may not play Crowley (thou it's made for user-Crowley), may or may not involve a time loop, may try to state Aziraphale's sex.
