Mistress Isabella sat comfortably on the soft, plush toilet seat, her luminous eyes fixed on the webcam as she watched her sissy slurp up the last bits of her shit. The smell of feces and urine filled the room, making it slightly nauseating for anyone else but the sissy who was kneeling before her.
The sissy looked up at Mistress Isabella with teary eyes, pleading for forgiveness. "Please, Mistress," he whispered, "can't I have some water to cleanse my mouth?"
Mistress Isabella let out a cruel laugh. "Oh, how pathetic you are," she said, shaking her head in disgust. "Drinking my piss is your punishment, and you will not be allowed to cleanse your tongue until you've swallowed every last drop."
The sissy gulped and began to drink, his face contorting with disgust as the warm, salty liquid trickled down his throat. It took several long, agonizing minutes before he finally managed to empty the glass. He looked up at Mistress Isabella, waiting for her approval.
"Good boy," she said with a hint of mock sincerity. "Now come here and taste my ass."
The sissy closed his eyes and bowed his head, preparing himself for his next task as Mistress Isabella leaned over the side of the toilet and presented her asshole to him. He hesitated for a moment before opening his mouth and tentatively tasting the anus that had been filling his stomach only moments before.
As he worked his tongue around her puckered opening, Mistress Isabella groaned in pleasure. "Ahhh, that's it," she purred. "Tongue-fuck my asshole."
The sissy obeyed, thrusting his tongue in and out of her ass as she watched, her eyes filled with lust. After a while, she pulled her asshole away and stood up, her black high heels clicking against the tile.
"Now clean yourself up," she said coldly. "We have much more fun to get to later."
The sissy nodded and got to his feet, wobbling slightly as he regained his balance. He wiped his face and hands with a tissue, trying to rid himself of the filth that permeated every part of him.
As he walked out of the bathroom, he could hear Mistress Isabella's voice calling after him. "And remember, sissy," she said with a smirk, "you're mine to use however I see fit."
The sissy shuddered at the thought, but he knew it was true. He had surrendered himself to Mistress Isabella completely, and he would do whatever she asked—no matter how degrading or humiliating it might be.
