Mistress Anna sat comfortably on the throne, surveying her domain with a look of amused disdain. Her slave was hunched over under the toilet seat, its face practically hidden by the side of the bowl as it eagerly lapped away at her asshole. The sight filled her with a perverse sense of pleasure, but she knew there was always room for improvement. After all, being the perfect toilet meant never forgetting one's duties – even if they were as simple as saying "thank you" when one deserved it.
With a slight tilt of her hips, Mistress Anna allowed herself a moment of indulgence, feeling her powerful asshole engorge with pleasure as it rose up from beneath her glowing orifice. She let out a low moan, her voice echoing through the room as she savored the feeling. Finally, she decided it was time to reward her pathetic worm with its due.
"Surprise!" She exclaimed, her voice echoing through the chamber. As if in response, her asshole squeezed tightly shut before releasing a rapidly expanding torrent of diarrhea directly onto the slave's face. The watery liquid splattered against its cheeks, nose, and lips, making a lovely mess of the once-human features. It was truly a beautiful sight to behold.
Mistress Anna chuckled in delight at the spectacle before her, unable to contain her amusement. She leaned forward, studying her slave's reaction with a mix of satisfaction and anticipation. Its mouth was already full of her foul offering, unable to form words of thanks or complaint. But that was precisely why it was her slave. It had willingly surrendered its humanity for her amusement, and she would not let it forget that fact.
With a cruel laugh, Mistress Anna reached down between its legs and gave its pathetic, engorged cock a sharp slap. The sound echoed through the room, followed by a small gasp of surprise from the slave. She could imagine the sting of the slap, the sharp bite of pain that would remind it of its place. And as if that weren't enough, she spat directly onto its still-twitching member, sending another shockwave of humiliation through its already-broken form.
"Thank you..." The slave managed to gasp out between mouthfuls of foul-smelling fluid. Its voice was barely more than a whisper, but it was there nonetheless – a reminder that even in its most degraded state, it still remembered its place as her toilet. Mistress Anna smiled, satisfied with her little lesson. After all, a Mistress's work is never done.
