Mistresses got a new slave who told them that he specifically liked drinking pee. At first, they thought he was joking and decided to set up a session with him. They wanted to see how much piss he could take before he tapped out. After arranging everything, they called him over and took turns pissing into his mouth. The slave, on the other hand, swallowed their pee greedily and kept asking for more. The mistresses were quite stunned but happy to have found a new human toilet.
