Jeff sat on his chair thinking for a little bit before settling on a rather werid choice, what if he swapped his ass with his mouth. Trying to eat through his asshole and poop from his head sounded very werid, and very fun to try.
Typing his commands into the chronovac and setting the timer for the length of the transformation Jeff sat on his chair for a few moments before a tingling started in his mouth and ass. Pulling his pants and underwear off Jeff forgot about his changing mouth to watch the real show in the mirror. He watched as his asshole between his cheeks stared to stretch, before settling on a line position. Jeff tried to control the muscles in his ass and surprisingly he got his changing asshole to open.
A long slimy red object was forming in his asshole from his very in the mirror, knowing this was his new gouge he tried to flick the growing tough out of his ass, and surely he did, leading to the hilarious sight of a red object poking out of his ass and spitting. Teeth grew into his ass mouth and sure enough he now had a mouth where his ass used to be.
Standing up Jeff observed his now pukered face, seeing his asshole in the mirror like that made him on comfortable, but the mouth thing was worth it.
