Mistress Gaia and her friend arrive back at the dungeon to find their slave kneeling, waiting for them. They've been shopping all day and couldn't find a toilet. As they approach, Mistress Gaia speaks to her slave, instructing him to put on the funnel in his mouth. She grins wickedly as she realizes that this is going to be his lucky day - or at least part of it.
Both Mistress Gaia and her friend had to go desperately, and there was no better target for their golden showers than their loyal slave. Without hesitation, they take turns sitting over him, allowing the flow of their urine to fill his mouth through the funnel. He can feel the warmth of their piss as it fills his mouth and runs down his throat.
Despite the discomfort he's feeling, the slave knows that this is his job – to serve and obey his Mistresses in every way possible. As they finish relieving themselves in his mouth, Mistress Gaia removes the funnel and orders him to open wide. With a gleam in her eye, she watches as the last drops of her piss drip from his chin and fall onto the floor.
"Swallow," Mistress Gaia commands.
The slave obediently swallows every last drop of their pee, savoring the taste as best he can. Even though it's humiliating, he knows that this is what pleases them.
Once they're finished, Mistress Gaia instructs her slut to kneel beside the slave and lick up any pee that has spilled. There is no wasting of their precious amber nectar - every drop must be consumed by someone. The slave watches, powerless, as his Mistresses enjoy the show and take pleasure in his humiliation.
As the day progresses, Mistress Gaia and her friend continue to find inventive ways to humiliate and dominate their slave. The golden showers are just one part of his training - but knowing that he has pleased them in some small way makes it all the more humiliating for him. He knows that he belongs to them, body and soul.
