Crowley lets out an appreciative hum at the feeling of Aziraphale's fingers on the back of his neck, at his touch. He presses another kiss to his neck, letting his tongue come out to trace the skin there again, to taste him again. He should probably take the time to move them where they need to go first, to get them situated where they should be, then focus on kissing the angel's neck, but, well, Crowley's always been a bit greedier than that. Another step backwards, and he's also going to kiss the column of his throat. He can certainly multitask in this situation.

With his newly freed hand, he moves it over to where Aziraphale is holding onto his trousers. He takes that hand, and carefully moves to loosen his fingers.
