We gave an in-depth interview to a female prison guard working at a rehabilitation facility called the Sexual Crime Prevention Treatment Center, who provides sexual treatment to severely ill solitary confinement prisoners. The female prison guard engages in sexual acts with "prisoners who have committed crimes in the past because of their strong sexual desires" in order to treat their addiction. Her professionalism, never showing her emotions while on duty, is a must-see. The female prison guard coldly and condescendingly performs sex on prisoners who cannot control their impulsive sexual desires, and she never lets her expression drop even when the prisoners suddenly have sex, thrust, finger, or do whatever they want to make them cum.
