Mistress Anastasia had a slave who was not as serious as he needed to be and that pissed her off. She had tried to talk to him but he did not change. And so she went out of her way to punish him and she made sure that the punishment was painful. The mistress slapped the shit out of him and she caught him off guard. That was the best part. He changed as he was not sure what else would catch him off guard.
