Mistress Mira caught her slave masturbating in her bedroom and she was angry. She did not care what he did to his own body but she did not want him to do it in her room. He had his own room and he had to confine such things to his room. To make sure he would never do that again, she cruelly tortured and punished him by riding him like a human pony.
This mistress had run out of ways to punish her slave. She is one of those mistresses who love to try different kinds of punishments. She does not like doing one over and over again as it is boring and secondly, she knows the slave will get used to it and render it useless. After brainstorming, she chose to punish her slave today by turning him into her human pony and riding him.
