他的妻子想要我惩罚他作为人类小便厕所

Today my new slave hands me a letter from his wife at the start of the session. She informs me that she is about to divorce him. She wants me to help her punish her husband and train him to obey women. Only if he submits completely to my treatment, she will stay with him. The list of all his misdeeds is long. Therefore, I'm going to give him a hard time today. He will have to swallow my piss and other things completely... or I will report to his wife that he has failed. Will he manage to save his relationship? He'll have to serve me as my human toilet and carry out every single order without question...
