[Aziraphale doesn't mind a little mess, but if they're going to be lying here for a while, he'd rather not have their skin get all tacky. He settles against Crowley with a content sigh.]

[The most comfortable he's been since... well, ever. He glances at Crowley sidelong, considering his suggestion.]

I've never taken a nap before...

[Although if there ever was a time for it, it would be now. Physically sated and emotionally wrung out, but in a good way. It's a lot of work to tear down so many emotional barriers. He pets Crowley's hair, then slides a hand down his lithe frame.]

I'll give it a try, my dear. And even if I don't fall asleep, I'll stay here with you as long as you'd like.
