Guolin works as a nurse at a hospital. One day, her ex-boyfriend, whom she broke up with because he was such a jerk, is hospitalized, and Guolin is assigned to take care of him. As always, the scumbag with a strong sex drive exposes his erect penis and demands sexual assistance. Even though they are engaged, Guolin can't forget the penis he used on in the past, and she can't resist giving in. From that day on, a decadent sex life in the hospital begins.
