"Sex Crime Eradication Therapy Institute" is a rehabilitation facility where a female guard has been closely followed for three years. The record of a female guard from her rookie days to the present, engaging in sexual acts with "prisoners who have committed sex crimes due to excessive sexual desire" as part of dependency treatment. It is a part of the daily routine for guards to engage in sexual acts with prisoners who have been incarcerated for past sex crimes. The professionalism of never showing emotions while on duty is a must-see. Against prisoners who cannot control their impulsive sexual desires, the female guard coldly and professionally performs sex from a superior position. She also casually makes them cum through sudden penetration, pistoning, or hand jobs during their outbursts, but the female guard never changes her expression.
