A fierce battle ensues between female students and office ladies who are confident in their pee-holding abilities! The pee-holding veterans arrive at the venue with their bladders fully filled. They all have expressions of pain on their faces, but Hitomi are shining with determination to win. The battle is quite simple. They take turns drawing a command card from the theme box, and the one who can hold out the urge to pee the longest by completing the instructions written on it while holding out the urge to pee is the winner. The confusion and embarrassment of meeting each other for the first time is a highlight, but the harsh commands such as jumping, bladder punching, and letting out a single drop are also worth watching. This is an irresistible masterpiece for those who want to see the limits of endurance and the amount of urine produced.
