This mistress did not like how this guy behaved. So she laid a trap for him and he took it hook line and sinker. The mistress showed him her ass and her pussy and he loved it. The mistress knew she had gotten him where she wanted him and so she concentrated on dominating him. She shocked him by shitting on him and peeing on him and he could not do anything about it.
Mistress Zephy did not want to deal with a cheeky person but this guy was and he did not want to change despite her repeated attempts to make him change. She changed tact and she used her shit to dominate him. The mistress made sure that the guy felt a lot of pain as she caned him in the ass repeatedly until he could not sit properly for a few days.
Mistress Zephy found her slave to be nauseating and she did not want to deal with his nauseating qualities. So she used her shit to dominate him and make him change into the kind of person she wanted him to be. The mistress enjoyed watching him eat her shit and she also loved how he became quiet and did all that she wanted him to do. She knew that it was the perfect punishment.
Mistress Zephy is a sadistic person and she loves it that way. She does not really care about other people and she loves it when they are miserable. If she was behind their misery, even better. And today she did it perfectly as she teased this guy and got his blood boiling with desire for pounding her but he ended up being used as a human toilet and made to eat shit.
