Nurse Hikaru Tsukimura accompanies a doctor examining a man with a mysterious illness. When the doctor suspects his condition is tied to sexual frustration, Hikaru puts her body into the treatment and starts getting intimate with the patient. What began as medical role-play soon turns her on for real, leaving her moaning loudly with pleasure. The aroused doctor joins in for a threesome, and Hikaru is worn out by two cocks as she orgasms again and again before taking consecutive raw creampies. The patient recovers, and everyone leaves satisfied.
