Don't think for years this hasn't crossed my mind, besides paws in maws of course. I've always wondered how the concept of "paw vore" would work and it never sat quite right with me in a way that made me say "this works, I can roll with it."

Closest to it is like absorption, whether physical or goo, and it's like the closest to it working.

With that said, I've seen a paw with a maw on it before, a couple of friends played with this idea and I'm not gonna lie, it's pretty cute and has me curious. If it was something I saw more, maybe I'd be interested? I know someone else that played with that concept with mouths manifesting on feet more particularly, but their character was also a human-shaped tentacle monster, so it had a lot more than that going for it xD

But yeah, I'm curious enough to see if that kinda thing would interest me to play with such an odd concept!
