This facility is the only one in Japan that treats prisoners dependent on ejaculation. The inmates have excessive sexual desire, causing disruption in their daily lives. This is a three-year record from when beautiful female guard O-san was new to her current position. 'I myself will perform sexual procedures on the inmates.' During work, she never shows emotion, maintaining a strong professional consciousness. When dealing with inmates who cannot control their impulsive sexual desires, she coldly performs sex in a riding position from above and allows them to ejaculate, penetrate, or masturbate freely during their fits. The female guard never changes her expression. Even at the height of orgasm, she shows no emotion. Instead of making sounds, she blows a whistle.
