You wake up in a labratory room. a scientist injects you with something that causes your body to grow fur. your your hands and feet painfully turn into paws. your back hurts as you grow a wolf tail. and your ears painfully turn into wolf ears. your body also seems more female, you were a boy before. you feel like your being crushed as you suddenly shrink into a baby. you are now an baby anthro wolf girl. it seems that the effects are permanent, so you won't be able to return to being human.
