Good. He wants to distract Aziraphale, he wants him overwhelmed by sensation and feeling, out of his head where he's always thinking so much. Always thinking, always contemplating and overthinking things. He just wants Aziraphale to feel with him.

He traces a hand up to guide with his mouth, curling around Aziraphale's shaft as he moves up and down. It's easy, really, to touch the sensitive skin on a human body and get a reaction. It's something different to be intimate. Fucking, for what it is, is something that humans do and they do regularly. But this? What they're doing? It's different---at least to Crowley. He's never been with someone he loved. He's never loved anyone but Aziraphale. And he's feeling Aziraphale's feelings, feeling them muddle and brighten with his movements. Humans don't have that connection between them.

I will give you anything you want, he tells the angel. Just say the word.
