Manami is sorting out documents at the nurse center during the night shift.A male patient comes there. He helps the male patient who says he can't sleep, but the male patient utters surprising words. "You're having an affair with Dr. Endo, aren't you? If someone at the hospital finds out, it'll be hard to stay," he said.She had an affair with a male doctor who works at the same hospital. "I can't masturbate in a hospital room because it's a big room. You know what to do, right?" Manami who takes me to the operating room, "Let's go to another room here...".In the middle of the night, the empty operating room is silent... She can't refuse the patient's request, "Please show me masturbation," and Manami-san exposes her dementia.But this ignites her libido.She begs herself, "Please let me lick you!"Forgetting that she's a married woman, the whole story of the most nasty nurse who is alive at work!
