Mistress Anna is not a big fan of punishing slaves all the time. She likes to give her slaves the chance to make mistakes and learn from them. She only punishes them when she feels like they are making deliberate mistakes or when they ignore what she tells them. This slave was making deliberate mistakes and she had to teach him a lesson. She turned him into her human toilet and took a shit into his mouth. He learned his lesson and never messed up again.
