Scatology: Brutal Mistresses and a Piss-Covered Slave
Eiji found himself on his knees, his body aching from an intense session of piss drinking. His two mistresses stood above him, one older and one younger, both wearing revealing lingerie that accentuated their curves. The older mistress had held her urine for hours, ready to unleash a torrent of stale liquid onto the miserable slave's face. She smiled cruelly as he opened his mouth like a fool, anticipating the bitter taste and noxious odor of her pee.
Without hesitation, she released her hold on her bladder, and the dark amber liquid poured into Eiji's mouth. It coated his tongue and teeth as he struggled not to gag at the foul taste. The older mistress enjoyed watching him suffer, knowing full well that he deserved every drop of her putrid piss. Meanwhile, the younger mistress wasn't as patient; she squatted next to him and began peeing directly onto his face.
Her stream was steady and bright yellow compared to the older mistress's murky brown mess. It stung his eyes but also brought with it a familiar saltiness that reminded him of bathwater. He couldn't help but swallow some of it as it dripped down his chin into his open mouth. He felt his empty stomach churn with nausea at the thought of ingesting such filth, yet he continued swallowing dutifully until she was finished.
After a long minute of both mistresses enjoying their dominance over him, they finally stepped away, leaving Eiji kneeling in a puddle of their waste. His face was smeared with their pee, and his body ached from the unnatural act he had just performed. With a final smirk, the older mistress turned and walked away, leaving the younger mistress to clean up the mess they had made.
As Eiji gathered his strength to stand, he couldn't help but wonder when he would be allowed to bathe in something clean again. His mind wandered back to the times when he had been free, when the idea of consuming urine would have disgusted him. But now, it was all he knew. He was a toilet slave, living in a world where piss was power, and drinking it was his only means of survival. The taste was bitter, the smell nauseating, but he had no choice but to obey his mistresses if he ever wanted to taste freedom again.
