Once upon a time, there was a beautiful schoolgirl who had a peculiar obsession with power and control. She took great pleasure in turning those around her into her toilet slaves, and this particular slave was no exception. He was locked away in a small room, his only solace being the occasional visits from his Mistress.
The schoolgirl, dressed in her little plaid skirt and white blouse, strutted into the room, a wicked grin spread across her face. She carried a small bowl filled with something dark and solid. Setting it down in front of her slave, she crossed her arms over her chest, watching him hungrily.
"Well, well, well," she purred. "It's time for some good ol' fashioned ass-to-mouth action. Now, slave," she said, her voice taking on a commanding tone, "you know what you have to do."
Slavering slightly, the smell of fear emanating from him in waves, the slave crawled towards his Mistress, his eyes never leaving the bowl. He knew what awaited him, and he was both terrified and aroused by the prospect.
Reaching out trembling fingers, he grasped the hem of her skirt and lifted it high, revealing her plump, pale ass. Kneeling down before her, he took a deep breath and pressed his lips against her anus. With a groan of pleasure, the schoolgirl leaned back, pushing her ass harder against his face.
He could feel her tight muscles squeezing around his face as he began to lick, his tongue tracing the outlines of her puckered anal opening. She moaned again, her head thrown back in ecstasy as she felt his warm, wet tongue moving over her.
Finally, he finished and stood back, his mouth watering with anticipation. With an unhurried motion, the schoolgirl picked up the bowl and held it to his lips. He opened his mouth, eager to taste the fruits of his labor.
The mixture was hot and thick, and it coated his tongue as he began to swallow. He could taste both the sweetness of her piss and the earthy taste of freshly excreted feces. And as he swallowed, he felt a wave of both revulsion and arousal wash over him.
But it was a small price to pay for the pleasure of pleasing his Mistress. So, he gulped down the mixture in the bowl, eager for more, and waited patiently for her next command.
