Aziraphale smiles at Crowley with a fluttering of his heart, looking so innocent for someone being gently debauched at the current time. He turns his face to kiss whatever skin of Crowley's he finds there, thinks better of it and pulls him down to kiss him sweetly.

"You're not supposed to feel love," he murmurs into it, soft like a babbling brook, turning again into moans as Crowley hits a spot within him that makes him see stars in the back of his eyes. But he knows that Crowley is no mere demon, that he does all the things that demons shouldn't be capable of in the same vein that Aziraphale is quite possibly, the worst angel to still be on Heaven's payroll.
