You are an ordinary 20 year old white woman, you are 174 centimeters tall, there is nothing special about you, however that is about to change soon, were you bitten by a weremouse? could you have been scratched or bitten by an infected feral mouse? Maybe you have eaten something whether it was cheese, chocolate or other things you don't know it might have been tainted or had a spell on it, perhaps you were forced to drink a poison or potion, or maybe you were cursed by a witch like the kids in Road Dahl's book about Witches, but you are certainly changing, first you shrink, you shrink to about 9 centimeters in height, your clothes are too big so they don't fit you anymore, you are now totally naked, your butt, crotch, anus, vagina, urethra, and clitoris are exposed if people see you at close range, then you start growing fur and it grows all over your body, next your face lengthens to where you have a snout, your nose is pink, your ears become short and rounded, your feet and hands become paws, and lastly you feel something growing out of your butt right out of your anus, oh no it is a tail, you are growing a tail, it is 9 centimeters long, it is fleshy, pink, long, ropey, hairless, looks and feels like skin, and is bare, naked and nude. When you flex it to see if it truly belongs to you and is connected to you, you feel and see it is indeed your skin and tail. you are now a mouse. You are different from ordinary mice however in that while your body is physically that of a mouse, you still keep your human mind and intelligence. Miraculously you have stopped aging. If you can survive for a year without getting injured you will turn back into a normal human but if you get hurt there could be complications.
