You enter the barn and the doors shut locked behind you, even worse your clothes are destroyed leaving you and your human boy bellybutton or navel or belly button, penis, scrotum, balls and anus exposed, nude and naked, in front of you looks like there are two doors, one will lead you safely to the next room like this one, the other leads to either a milking machine, a baby milk bottle, a milk bottle, a, a milk carton, milk jug, a milk pail, a milk bucket, milk canister or milk barrel. You have to get through a lot of rooms to get out of this room safely unchanged.
If you pick the wrong one of the two in any of the rooms, either your penis will get milked by the milking machine, this will kill your human life and turn your body, spirit and soul into either an anthro cow with a human mind or they will turn your body, spirit, and soul into a feral cow with a human mind. If you are a little less unlucky they will have baby milk bottles, milk bottles, milk cartons, milk jugs, milk buckets, milk canister, or milk barrels. You will have to pee into these if you encounter them and this will gradually change you one body part at a time for each one you encounter, get changed too many of your body parts changed and your human life will die and your body, spirit and soul will turn into either an anthro cow with a human mind or they will turn your body, spirit and soul into an anthro cow with a human mind.
Good luck.
