Mistress Misia did not want her new slave to misbehave. That is why she opted to deal with him in a cruel and ruthless manner so that he knew from the word go that he would never mess with her and go scot-free. The mistress took him to the woods and she made him drink her pee before she let him go. She did not say much but he learned his lesson.
Mistress Misia and her friend did not like how they caught this slave jerking off and they had to punish him so that he did not do that again. He could do it in his room or when he was showering but not in the living room. The mistresses cruelly peed on him and made sure he was humiliated before they let him go and told him not to do it again.
