A drooling asshole?

....a drooling winking asshole. It looked like how had gotten a pussy juice enema.

"Oooh please Master! It feels so warm, my ass is literally becoming a asspussy for you to knock me up with."

You reach out and easily slide two fingers in. As you feel around you could quickly tell it has changed. The inside was much more stretchy and wet this definitely no longer a normal asshole.

"It feel so interesting to have your ass change into a breeding sexual organ. You might or might not have noticed yet but sex demons don't produce 'waste' so everything down there is completely for pleasure, I mean you could, at least I'm not sure. Some partners enjoys being peed on, then you could just do that on command, but I don't wanna get into that. But the key thing master I'm now your little breeding trap now."

As he said this he swayed his sexy ass at you

"Want to give it a test drive."
