Mistress Medea wanted to make her drunk man drink pee. She peed into a wine glass and she then took it to him. She was sure that he was so wasted that he could not tell the difference. She had fun making him drink it and he only realized it when he woke up and he was smelling like pee. When she pretended to ask him why he smelled like pee, he told her it happened in a bathroom stall.
Mistress Medea does not like timid people and when she noticed that her slave was timid, she knew she had to do something about it. She felt that peeing on him and humiliating him was the best thing she could do in the circumstances. So she went ahead and she peed on him and made sure that he drank all of her pee. He tried his best to stop being timid.
