Shizuka works as a nurse at a hospital in Tokyo. One day, her ex-boyfriend, who couldn't stand the trouble he caused her, is hospitalized and Shizuka ends up taking care of him. The scumbag still has a strong libido and shows off his erect penis, demanding sexual assistance. Even though she is engaged, Shizuka can't forget the penis she once enjoyed so much and accepts it. From that day on, her depraved hospital life began.
