Mistress Alessa and her friend realized that they had an unruly slave who needed to be punished in order to change him. He had to be punished in a way he had never been before and that is what the mistresses did. The mistresses cruelly made sure he was drenched in pee before they let him go. They waited for him to refuse to drink pee so that they could crush his balls but he did not refuse. He did it as ordered.
