Had it been literally anyone else in the entire universe asking him to "make love", Crowley would probably have laughed. After all, he was a demon, and while he was a pretty terrible demon and awful at being everything a demon was, he still didn't do something like make love. That was, well, it was something that teenagers did when they were trying to make an excuse for their hormones, or that married people did after a fight or whatever.

But this is Aziraphale asking. And Crowley would do anything for Aziraphale.

He releases the angel's shaft with his lips and kisses upwards this time, moving up to capture his mouth with his own. He kisses him soundly before murmuring against his mouth: "Tell me what you want."

After all, Crowley is a flexible demon, as well.
