Aziraphale kisses him again, and Crowley leans up, meeting him as he leans in. He's wanted this for so long, it's sort of impossible to think it's happening now. To think that Aziraphale wants it----no, no, that isn't what's impossible. It's always been an unspoken feeling between them, a knowledge of how they felt that they just didn't act on. No, it's impossible that they've finally acted on it. Six thousand years later, finally here, in Crowley's mostly empty flat, kissing at the end of the world.

He shifts his body closer to the angel's, deepening the kiss. And, because Crowley is, at heart, a totally shameless demon, moaning just a tiny bit against the angel's mouth.

In only a short time, he has to go back to being an advocate for all of the humans on Earth. For this moment, he's just going to be himself with the only person on the planet he cares about.
