As the young, pretty schoolgirl continued pushing against her own asshole to expel the remaining solid feces, a sense of desperation began to take hold. Her face was contorted in concentration and pain, tears flowing freely down her cheeks. She looked absolutely miserable, but she knew that she had to keep trying.
With one last heave, she finally managed to force out the last of the shit, wincing as it slid past her sphincter. A moment later, she felt a wave of relief wash over her. Her back arched slightly as she let out a sigh of exhaustion.
Looking down, she saw the human toilet's mouth eagerly waiting below. Without further hesitation, she lowered her trembling, quivering ass onto its lips. The toilet's tongue darted out, licking at the base of her anus, eager to taste every drop of filth she had inside her.
The schoolgirl let out a shuddering moan as warm, slimy tongues began lapping at her ass, cleaning out every last bit of shit from her tight asshole. She felt a rush of pleasure and submission wash over her, knowing that she was in control of this situation.
As the toilet continued to worship her ass with its tongue, the girl reached down between her legs and began fingering herself, moaning loudly. She was horny and aroused, her pussy dripping from her own excitement.
Suddenly, she pulled her fingers away, revealing that she had torn loose a new piece of her panties, soiled with her juices. She lowered it towards the waiting toilet, smiling as it eagerly opened its mouth to accept the soiled underwear. In one swift motion, the toilet devoured the soiled fabric, swallowing it whole.
The girl felt a rush of dominance course through her veins. She was in control of this toilet, making it worship her ass and clean up after her. With a wicked grin on her face, she leaned forward, her ass hovering just above the toilet's open mouth.
"Now," she purred, "it's time for you to taste what you've been waiting for."
With that, she lowered her ass onto the toilet's tongue, feeling it slide inside her as the toilet began lapping up her fresh urine. Its tongue flicked against her sensitive walls, sending shivers of pleasure through her body.
As she rode the toilet's tongue, she reached down and began playing with her soaking wet pussy once more, her moans echoing around the room. She was in total control, using the toilet as she saw fit.
Finally, when she sensed that the toilet had had enough of her urine, she slowly pulled away, smiling as she watched it eagerly lap up the last drops that had spilled onto the floor.
"Good boy," she purred, standing up and stepping off the toilet. "Now clean yourself up before I use you again."
With that, she turned and walked away, leaving the human toilet to lick up the last traces of her filth. She was the queen of this toilet, and she ruled with an iron fist dipped in shit.
