"I will never show a face of pleasure while on duty, no matter how good it feels." This is Japan's only facility that cares for ejaculation-addicted prisoners, and this video is a record of the beautiful female prison officer A-san who works there, from her student days to the present. The warden provides sexual care to the inmates. Without showing any emotion, she calmly performs cold and high-handed acts in the cowgirl position with prisoners who have uncontrollable sexual desires, and her expression never changes even when the prisoners engage in impulsive insertion, violent movements, or manual stimulation as they please. Even when reaching climax, she never lets it show on her face, and even when squirting, she insists she hasn't come! "If you don't put on a condom, you're going to the punishment cell!"
