"I think it's important to never show your emotions to the inmates, whenever possible." This is the only facility in Japan that treats prisoners with ejaculation addiction, and this video is a three-year record of K, a beautiful female prison guard who works there, from her rookie days to the present. The guards administer sexual acts to the inmates. They never reveal their emotions, and with the inmates who can't control their impulsive sexual desires, they perform cowgirl sex with them in a cold, condescending manner, and they keep their expressions on their faces even when the inmates make them cum as they please, including sudden penetration, thrusting, and fingering. Even when they climax, they never show it on their faces, and even when they squirt, they don't cum!
