Hot off the presses, kink and cosmic power.

Though right now just kink, it hasn't gotten to the cosmic power bit. But it does have what I feel is a quite fun completed kinky sex scene, so there's that. :D

Summary:

Crowley has had six thousand years to construct fantasies about Aziraphale, so it's perhaps unsurprising that some of those fantasies got a little...wild. Now, with the two finally together, said wild fantasies are in danger of escaping from Crowley's mind and getting blurted out at some inopportune moment, which would be the worst thing ever. After all, there's no way the sweet and innocent Aziraphale would be into anything so depraved and kinky...

Exploring domination together is about to open a giant can of worms, though, for as they grow closer, Crowley gives Aziraphale his true name, and in doing so sets something in motion that will end with him discovering an immense power. And while Heaven isn't watching, Hell might still be, and they aren't about to let somebody like Crowley out of their grasp.
