Everything started with the encounter between Ryuji and "Narumi Jinguji," which was the first experimental material. Narumi, the director of the Gynecology Bureau at St. Juliana Hospital, asks the nurses in the "special ward" to train and discipline to serve male patients. The first target is "Nanase Koi", the second is the chief "Reimi Shinshiro", the third is the pharmacy "Ako Fujisawa", and one after another, we find the weak points of the nurses. When I put it in, I trained, and while I was afraid of the overflowing pleasure, I gradually put it in the meat urinal.
