Erina, a married woman who applied for sexless between couples, was handed a condom and decided to stay overnight at a college student's house. She uses a rubber as soon as possible to finish sex, but she allows sex without a rubber to a man who is not satisfied with one ejaculation. The two of them pretend that the second sex never happened, but they can't forget the pleasure of life and end up asking each other again as it's time to go home.
