Tonight was my first experience with being turned into a donkey by HeadMistressSquirrel. Her method was amazingly subtle and quick. I don't know if it would have worked nearly as well if I hadn't been in a chat room with multiple "donkeys" braying away. Once it kicked in for me, it was intensely arousing! While I never really felt any physical transformative effects, the mental impact was significant. I basically felt like a simple, rutting, horny, donkey with no thoughts beyond making noise and feeling good. Well done HeadMistressSquirrel!
