Emma groans with self-pity between mouthfuls.

You'd think it would get more tolerable, but each gulp is just as horrid as the last. She wriggles against her restraints, but they won't budge. She has to remain here, squatting uncomfortably, strapped in front of the hole that's been cut in her wall, until one of her release conditions are met.

The blue logo of a man and woman on the front of her sweaty skin-hugging latex catsuit serves as an extra humiliating indicator of her role until she is released - she is her son's living human urinal.

The large rectangle that's been cut out of her wall was done in order to give the robots access to the upper bathroom's sink's drainage pipe. It took the machines less than 5 minutes to rework the plumbing so that everything that goes down that plughole is now delivered straight through Emma's ring gag and into her mouth. The seal is almost completely water-tight, meaning that the only place for that liquid to end up is down her throat and into her stomach.

A device behind her will automatically release her restraints when one of three conditions are met:

1) Her son comes downstairs and sees her like this.
2) Her son uses the toilet to urinate instead of the sink.
3) Anything other than urine is about to be sent down the sink's drain.

The Motivator clearly thinks she might be stuck here for a long time, because in addition to the degrading catsuit, it has included a humiliatingly thick and well-padded diaper underneath. The super-absorbent padding at her loins will be the final destination for all the piss that comes out of her son's bladder, after it's made its journey through her own stomach and waste processing systems.

Furthermore, her legs are already starting to burn from being **** to hold this uncomfortable squatting position, adding to her discomfort and displeasure.

But there's nothing she can do but hold this painful squat and drink her own son's disgusting piss.

Despite her sore, throbbing asshole and clit, she'd rather be tied back to the Punishment Chair.
