An Apple of Good and Evil
This is by far the filthiest thing I've ever written...so I have to share part of it here. But not all of it. If you want all of it, you have to go to AO3 and read it.

Slowly, quietly, Crowley slipped up behind the desk chair. He leaned down beside Aziraphaleβs head and took a deep breath. Oh yesβ¦oh his bastard of an angel was certainly pleasuring himself to the image on the screen. Careful so as not to get himself stuck, Crowley let his control of his human form start to slip. His clothes melted away as his lower half took the form of his natural snake self. He kept his upper half human as best he could, save for his tongue and teeth. Those he let shift as well.Β
βPleassssssuring yoursssssself, angel?β He hissed softly, letting the tip of his forked tongue come out to flick against Aziraphaleβs neck and ear. Oh he tasted and smelled devine.Β
Aziraphale gasped, quickly scrambling to try and close down the screen, only for his hands to be caught and held close to his body. Crowley slithered himself closer, seeking out the heat that came off Aziraphale in waves. So warm, so softβ¦
βMmmmβ¦my angelβsssss found a kink, have you?β
βC-Crowley! Whatβ¦what are youβ¦ohβ¦oh dearβ¦itβs notβ¦Iβm notβ¦β
βSsssssshhhhhhβ¦ssssssssure youβre not. Jusssst like Iβm not, either.β Crowleyβs tail came up to slide over Aziraphaleβs leg, up his thigh, and settled large and heavy into his lap. It gave a playful flick before falling still again.Β
Humming, Crowley leaned down to nuzzle at Aziraphaleβs neck. The angel was helplessly trapped, right there in his chair, unable to do anything except let him nuzzle and lick and tease. A small whimper escaped him as just the tip of one of Crowleyβs fangs nipped the lobe of his ear. Keeping Aziraphaleβs hands in place with one hand, he used the other to run down Aziraphaleβs chest, but stopped when he noticed the stark difference from what had been there before.Β
βBreastsssss, Angel?β
Again, Aziraphale whimpered.Β
Crowley glanced at the screen for a moment, then turned his attention back to murmuring into Aziraphaleβs ear. βIssss that what you want? Did you change your Effortssss sssso you could feel what sssssshe feelssss?β
He licked across Aziraphaleβs neck, long and slow and sensually. He could literally taste the arousal rolling off him. It was thick and heady and was slowly starting to drive him completely mad.
