Mistresses were spending time together when one of their slaves came to them with a request. He said he wanted to play with all the mistresses. They were not really in the mood but agreed anyway. They asked him what he wanted, and he said he wanted them to help him jerk off. They told him he was going to pay for it by drinking the mistresses' pee, and he agreed. They took turns pissing in his mouth, and he drank their piss. The more he drank, the harder he got hard. By the time they finished, he was also ready to cum.
