Goddess Amanda wanted to have fun at the expense of this guy so she teased him as she played with her pussy. But that was not all as she chose to pee on him as well. But just before she peed on him, she decided to change tact and scare him with pee instead of actually having him drink her pee. He escaped that punishment but he had been humiliated nonetheless and knew what she was capable of.
Goddess Cici needed this guy to do something to stop his forgetfulness. That is why the mistress used her pee to dominate as well as humiliate him. The poor guy could not believe the kind of things she had in store for him and that she actually went ahead to do to him. The guy was made a human toilet and he was also teased and denied by the mistresses.
