Mistress Anna had always enjoyed having her privacy while using the toilet. Never before had she considered sharing such an intimate moment with another being, let alone a human being that she had reduced to her personal toilet slave. But as time went on and the slave became more obedient and accepting of its new role, she found herself allowing small acts of kindness and intimacy. Today, she decided to up the stakes just a bit.
The slave was brought into her lavish bathroom with anticipation building inside of them. They knew what was about to happen and they couldn't wait for another chance to please their Mistress. Mistress Anna was casually dressed in some sweatpants and a comfortable t-shirt that accentuated her curves perfectly. The slave couldn't help but stare at her beautiful body, taking in every detail as they were allowed this small gift of intimacy.
As Mistress Anna took her position on the toilet, the slave couldn't believe their eyes. Her pussy lips were spread slightly by the rim of the toilet seat, making her most private area vulnerable and exposed. The slave's cock, now permanently modified to be connected directly to their asshole, throbbed painfully with desire to be used by their Mistress.
"Tongue my ass, toilet," she commanded.
The slave didn't hesitate. They positioned themselves around the toilet bowl, their mouth opening up to reveal their now useless human lips that had been permanently sewn shut. Their tongue darted out, running over the exposed dark hairs of their owner's asshole, and delicately licking around the tight entrance. Their long, skilled fingers reached up to rub the swollen anal glands that protruded from her puckered hole. With each lick and caress, they could feel the warmth emanating from their own body, the remnants of their foul waste that still clung to them.
Mistress Anna squirmed with pleasure as the slave's tongue delved deeper into her ass, sucking and licking eagerly. The turds today were exceptionally fat and hard, and the slave had to work hard to get every last bit of shit from its Mistress's anus. As they worked, the slave couldn't help but wonder if this was their punishment for getting carried away with the realism of their modifications. They couldn't help but worry that they had gone too far and now were being forced to clean up after themselves.
But as they pulled their mouth away from their Mistress's now clean asshole, they saw the content look on her face. She was satisfied with their work and her body trembled with pleasure. The slave closed their eyes, savoring the taste of their Mistress's ass on their tongue. It was the most satisfying meal they had ever had, even if it was tainted by their own foulness.
When Mistress Anna was done, she stood up and turned towards the slave, her eyes gleaming with both satisfaction and concern. She leaned down and spat into the slave's waiting mouth, the warm saliva washing away some of the lingering taste of their own feces. The slave opened their eyes gratefully as she pulled back, slapping their face. It stung, but they knew it was a sign of affection from their Mistress. She couldn't allow them to forget their place in her world, even in moments of intimacy.
"Good boy," she said softly, her voice never more affectionate. "Clean yourself up now."
The slave got to its feet unsteadily, using the toilet to balance itself. They had never felt so full after a meal before. The mixture of their own waste and Mistress Anna's fluids churned inside of them, making them feel both dirty and wanted. They made their way to a nearby sink, looking down at their useless human body and remembering what they had become.
As they cleaned themselves as best they could, they realized that this was their life now - serving their Mistress in any way she desired. And even though it meant their degradation and humiliation, they would continue to do so for as long as she desired them. Such was the power of love and submission, even when it led to the darkest corners of human depravity.
