Saori stared in disbelief at the turd sticking out of her human toilet's throat. She had spent so much time and money training him; he was supposed to be able to swallow anything she threw at him. But here he was, choking on a piece of shit that he should have ingested without even thinking about it.
With a sigh of frustration, she picked up the phone and dialed the number of the training center. After explaining the situation to the faceless voice on the other end of the line, she was told that her toilet's throat had probably narrowed due to disuse. They assured her that all she needed to do was insert something long and rigid into his esophagus and push it back and forth until it stretched out again.
Saori ended the call and looked at the long, black dildo lying on the floor of her bathroom. It was the perfect tool for the job. She grabbed it and walked over to her human toilet, who was still gagging weakly as he tried to expel the turd from his throat.
She pressed the thick head of the dildo against his lips, and he opened his mouth obediently, desperate for relief. With a groan of both pleasure and effort, Saori pushed the dildo deep into his throat, feeling it scrape against his esophagus as she forced it down.
As she began to thrust the dildo in and out of his throat, Saori couldn't resist taking things a step further. She knelt between his legs and lowered her pussy onto the base of the dildo, pushing him even deeper into the act of fellatio. She moaned as she rode him, using his mouth as a personal pleasure tool while also forcing him to unclog his own throat.
After a few minutes of intense grinding, Saori finally felt the dildo slide down his throat more easily, and she pulled it out, leaving him gasping for breath. She couldn't wait any longer; she needed to use him as she had before her long absence.
She turned around and lowered her ass onto the rim of the toilet, taking aim at his open mouth. She released a torrent of urine, watching as it splashed against his face and into his open mouth. Satisfied, she turned back around and squatted over him once more, this time releasing a stream of liquid shit mixed with bits of undigested food into his mouth. She grinned as she watched him choke on the revolting mixture, knowing that he had truly earned his place as her human toilet once again. With a final thrust, she emptied her ass into his mouth, and he swallowed reflexively, his throat now as accommodating as it had ever been.
