After a long day of meal deliveries for his human toilet duties, the slave couldn't wait for the next round to begin. The previous visitors had gifted him with a rich variety of flavors, and he wondered what this new lady would bring. As she entered the lavatory, he knelt down eagerly, mouth already open in anticipation of her delicious feces.
The lady relieved herself gracefully onto the slave's open mouth, and he savored the taste of her warm, nutritious excrement. However, this was a new experience for him. He felt the unfamiliar weight of her shit pressing down on his tongue and filling his mouth as he struggled to keep swallowing. Her ass cheeks flexed, pushing more of the foul concoction into his waiting maw until it was overflowing.
"Why aren't you swallowing?" the lady demanded. "You're supposed to eat everything I give you!"
The slave nodded desperately, choking on the excess feces. He tried to swallow as much as he could while apologizing profusely for his incompetence. It was clear that this lady had an abundant supply of scat for him to consume, and he was worried about disappointing her.
"I'm sorry, mistress," he whimpered between mouthfuls of shit. "I'll try harder next time."
The lady watched critically as the slave struggled to empty his mouth before she released another steady stream of her waste. This time, she commanded him to clean up any spillage that might occur. The slave nodded eagerly, realizing that he had no choice but to comply with her wishes.
As the loads of feces piled up in his mouth, the slave felt his stomach churn with disgust and nausea. He wondered how much more of this he could take before his body gave out. But he knew that failing his mistress was not an option - he would do whatever it took to keep her satisfied with his toilet services.
Finally, after what seemed like an eternity, the lady relieved herself of the last of her meal. She stepped back, surveying the slave's position on the floor, covered in her shit. She smiled coldly, nodding approvingly at his devotion to her needs.
"You may rise now, toilet slave," she commanded. "And remember, next time you will not disappoint me."
The slave stood slowly, still feeling the weight of her feces in his stomach. He bowed humbly before her, his mind racing with thoughts of how he could possibly prepare himself for the next round of her scatological demands.
