「快楽を覚えようと、勤務中は絶対に感じている顔は見せません。」ここは日本で唯一の射精依存囚人をケアする施設で、この映像はそこに勤める美人女性刑務官Aさんの学生時代から今に至る記録である。看守が受刑者に性的なケアを処置。一切感情を出さず、抑えきれない性欲を持つ囚人を相手に、冷徹で高圧的な騎乗位での行為を淡々とこなし、囚人の衝動的な挿入や激しい動き、手での愛撫といった好き勝手な行為にも表情を一切変えないのだった。絶頂を迎えても絶対顔には出さず、潮を吹こうとイッてないと言い張る！「避妊具付けないと懲罰房行きだ！」

"Even if I'm experiencing pleasure, I absolutely never show any signs of it while on duty." This is Japan's only facility that cares for prisoners with ejaculation addiction, and this video is a record of the beautiful female prison guard A, who works there, from her student days to the present. The guard provides sexual care to the inmates. Without showing any emotion, she calmly and coldly performs acts in the cowgirl position with prisoners who have uncontrollable sexual desires, and does not change her expression at all even when the prisoners impulsively insert, move violently, or caress her with their hands as they please. Even when she reaches orgasm, she never shows it on her face, and even if she ejaculates, she insists that she didn't come! "If you don't use contraception, you're going to solitary confinement!"
