Guttershy’s transition to the role of living toilet was complete. First her mind was broken from months of public humiliation and piss-slavery, but there was still the issue of housing, feeding, dressing and cleaning her, and also her pesky penchant to move around too much when performing her piss-swallowing duties. Soon her owners decided to complete her transformation into an actual toilet. Her body’s functions; immunity, arousal and metabolism were further modified with illegal drugs and vile spells, her limbs… removed… under a dark magic operation, and her body dragged into a dark, dirty place under the floorboards to sit over a drain to dispose of any waste she produced herself, and finally, her mouth hooked up to a blackwater line above her. Viola! She was now a permanent toilet, no further maintanence was requried. In the convening months Guttershy forgot who she was, what life used to be like, for she was now a helpless meatsack in the dark, she couldn’t see, couldn’t hear, couldn’t move, was shut deep down under a drain, the only stimulation she could get, the only thing she had to look forward to, was a flood of fresh piss flushing down her troat every few minutes or hours, she was so disgusted with herself, but at the same time her mind was kept in perpetual lust, until she couldn’t even tell the two apart… Slowly the last fragments of her mind dissipated as she finally forgot about her old life and began to feel a great pleasure knowing that she would never be free again… She liked being a toilet. Every few minutes in the cool darkness, as another torrent of piss came rushing down the pipe to flood her mouth with warm, bitter foulness, a little rush of pleasure would go through her, nudging her closer to the orgasm she desperately craved for but could never reach. After years of being a toilet her mind descended into a mush of self-loathing arousal that could only be satisfied by piss.
