Xerxes had always been a loyal husband to his wife, Summer. However, when she caught him masturbating to one of Mistress Mystique's sensual videos, the world around him seemed to turn upside down. At first, he tried to downplay it, but Summer's reaction was anything but forgiving. She decided she would send him to Mistress Mystique in hopes that she could learn from her and teach Summer how to easily enslave men like Xerxes.
As Mistress Mystique began to train Xerxes, she put him in a strict chastity belt, ensuring that he would not be able to touch his own manhood for any reason. He quickly learned that his life revolved around his Mistress, and she controlled every aspect of it. She taught him that his role was to serve her in all ways, including using him as a human toilet when needed.
One day, Mistress Mystique commanded Xerxes to kneel before her while she relieved herself into his mouth. As he tasted her cum, he realized that this was only the beginning. From now on, he would only cum when she allowed him to, and even then, it would be while his mouth was full of shit or piss. The thought of being used in such a degrading manner both terrified and aroused him.
As Mistress Mystique finished, she ordered Xerxes to clean himself up before returning home to Summer. He couldn't wait to see the look on her face when he arrived with shit still on his face from his encounter with Mistress Mystique.
When Xerxes finally returned home, Summer gasped in disbelief at the sight of him. Tears welled up in her eyes as she realized what he had been put through. However, there was no denying the power that Mistress Mystique had over both of them now. Summer knew that if she wanted to keep her husband under her control, she too would have to submit to the leather-clad dominatrix.
From that day forward, Xerxes served as his Mistress's toilet whenever she desired. He came to cherish every moment he spent being used by her, even when it meant his mouth filled with her filth. For him, there was no greater honor than being so completely owned and controlled by a powerful woman like Mistress Mystique.
