This whole thing is weird: your head is stuck inside the wolf but you can still breathe, and the thing you've been fighting this whole time seems to be fixing your biggest problem. You could keep pulling away, you could keep trying to stop it, but at this point it seems like the best course of action would be to sit still and wait until it's completely finished licking the latex off your foot.
You wait a while as you keep hearing and feeling the pattern repeat, the squeak of its latex tongue against your latex foot fading away as it cleans another spot, and then the squeaking again as it moves to another patch of the rubbery stuff. It takes several minutes, but eventually it finishes and stops licking. But... your foot, it still feels strange. You bring your hands down to investigate, and find that it has removed all the latex... and at the same time, turned the foot underneath into the shape of what it was taking away.
You can feel your latex-free foot, now flesh and bone. You can feel the fur coating its top, the pads on the bottom, the big toes at the end. Finally, you can feel liquid running down your other foot as the wolf vomits all over it and then starts licking it clean. It isn't trying to fix you! It's trying to change you! Permanently!
