I been thinking about the brothers from Obey me and their demon form, like, awfully a lot
Just imagine fucking Satan so good that his claws are clinging to anything for dear life, and his tail is nothing better, it trashes under him and holds so thightly to whatever it is under him until to point of leaving cracks if not breaking it (he may get mad once he finally cold down but he won't really replaced it unless is something important or is completely broken)
Speaking of tails, while Belphegor's tail curls around you the more you thrust on him the less strenght it has and slowly let go of you, contracting and twiching while still lingering close to your body, while with Leviathan is the complete opposite, it graps around your waist or thight and won't let go for anything in this world, desperately trying to keep you close and keep you going, in fact, his tail tightnes to the point of leaving a mark when he feels his orgasm bubbling up in his tummy
And when it comes to wings we have Lucifer who will try with all his strenght to keep his wings from reacting, who will try to make sure his wings don't stretch or the feathers getting fluffy with how much he is enjoying having you over him, he tries to fight back his reactions until his strenght vanish complete and his wings stretch out completely. We also have Asmodeus who's the complete opposite, who shows off his wings with all the pride of the world and has no problem with letting you see how much his wings stretch and contract, not even how much they start to tremble and move around when he is getting closer to his orgasm, in all honestly he is quite proud of them and their reaction
In the other hand there is Mammon who's wings aren't as reactive as Asmodeus', his wings just trembles and twiches from time to time along with the rest of his body but when he is high with his orgasm and when he finally cums his wings go completely still, completely stretched out and firm before completely relaxing, almost like melting, as well, Beelzebub's wings aren't reactive neither, his wings tremble a bit along with him but they tend to twich and shake a few times, when he feels a new wave pleasure taking over him, it is quite adorable when it happens because is always accompanied with a groan that slowly turns into a louder moan
