You Steve Williams sat on the table & began removing your clothes as the doctor looked over your chart. "You want to become a red kangaroo right?" he asked. "Yes." you answered. "A doe kangaroo; aka a female red kangaroo?" he asked. "Exactly." you answered. He looked up from his clipboard & a was surprised to see you naked. "You're naked?" he asked surprised. "I'm going to have to be sense I'll be an animal." you replied. "Most are pretty reluctant even embarrassed to be naked." the doc told you. "I'm not one of them." you told him. The doc collected himself as he took the syringe out of his pocket & uncapped it & asked you "Why you want to become a female kangaroo?" "I have loved kangaroos sense I was a kid. As I got older I became a furry & my fursona is a doe kangaroo. I have finally decided to stop pretending to be a doe kangaroo & finally become it." you explained. The doctor just smiled as he injected you in the arm. You felt you privates tingling & you looked down to see them shrinking away. Soon you saw a pouch developing on your belly & saw your chest hair changing. "I'm becoming a female kangaroo!" you yelled overjoyed.
