This guy was too stubborn for this mistress and she had to do what she needed to do. The mistress felt that the best thing to do to him was to humiliate him and to ensure that she taught him a lesson no one else had taught him. That is why she turned him into a human pony and she had a great time torturing him. He never saw it coming.
Princess Kirstin and mistress Missy had nothing better to do with their time and they felt that they had to find something fun to do. The mistresses settled on dominating as well as torturing the guy and doing it in a way that he had never felt. The guy was in a lot of pain and he cried but the mistresses did not listen to him and they instead laughed at him.
