Nurses working at a pornographic hospital follow a rule of fulfilling every patient request. When a new nurse joins, unaware of the true nature of the job, senior nurses begin training her in explicit techniques. They make the rookie nurse take a cock in her mouth and instruct her to meticulously clean the shaft with her tongue. The inexperienced nurse is forcefully penetrated and involuntarily writhes in pleasure. Her reactions satisfy the senior nurses, who continue their sexual instruction with enthusiasm. In the end, the new nurse and three experienced nurses line up together for a public sex lesson.
