Mutated Demonflesh (Patreon)

The female demon opened her legs and mandibles slowly, revealing rosy and moistflesh dripping with fluids. Suddenly thoughts appeared in your head which didn't seem to be yours: 

"I think this is very attractive and inviting.  Ah, the asymmetry of her horns and mouth flaps..."

After a while you stopped questioning these strange thoughts, as a massive erection announced itself.
