Mistress Gaia watched her two slaves with disdain. They were pathetic excuses for servants; they couldn't seem to do anything right. It was a shame, really, because she had invested so much time and effort into training them. She had hoped they would be capable of performing various tasks around her studio, but they were completely useless in every other area except one. They made excellent human toilets.
Today, she decided it was time to put their skills to the test. She ordered the first slave out of the cage and onto the floor, instructing him to lie down and open his mouth wide. She straddled him and let out a giant turd, which filled his mouth completely. The slave began to gag and choke, his eyes watering from the disgusting taste. Mistress Gaia slapped him hard across the face, forcing him to swallow the shit. He struggled for a moment, trying to get rid of it, but soon enough, he had no choice but to swallow every last bit. She taped his mouth shut, ensuring he wouldn't vomit it back up.
Next, she called for the second slave. He approached her eagerly, ready to please his Mistress in any way he could. She repeated the process, except this time, the slave swallowed the shit without issue. He had no problem accepting his role as her personal toilet slave. Mistress Gaia was impressed; this one might actually be useful after all.
With a satisfied smile on her face, Mistress Gaia continued to use her slaves as human toilets throughout the day. They took turns being both the toilet and the disposal system - flushing their shit down the drain or into a diaper. Their purpose in life was to serve her in the most humiliating way possible, and they seemed to enjoy it. She watched them grovel at her feet, thanking her for the opportunity to be used in such a degrading manner.
As the day went on, the smell of excrement filled the studio, but Mistress Gaia didn't mind. She had trained her slaves well; they were nothing more than living trash cans now. Their worth had diminished to the point where they no longer had any rights or dignity. They were hers to use as she pleased, and she would make sure they knew their place.
