The 'My Human Toilet' trend has become popular among the girls at this academy. With their good metabolism and youthful bodies, they urinate frequently throughout the day, often needing to use the restroom. However, since the academy's toilets lack a cleaning function, naturally, a lot of tissue debris sticks to their labia majora and minora. Their urethras also start to smell like urine, so they have the sensitive male transfer students clean their stinky pee, drink it, and use them as 'human toilets'.
