Topic: Machine or "Magic Trick" TF

I wonder if there exists any stories where women disrobe naked and they step into a machine or a box (or something concealing them) and once concealed inside, they transform into bizarre to disgusting things imaginable?

Or another example would be a "Toy Factory" where women disrobe nude and step into a assembly line once they're inside of the machine, it transforms them into a random toy that resembles nothing like their original selves?
