Nanao, a married woman who applied because her husband and I are not having sex, is given one condom and decides to stay the night at a university student's house. They quickly have sex using the condom, but she allows the man to have sex without a condom because he is not satisfied with just one ejaculation. The two pretend that the second time never happened, but they cannot forget the pleasure of the raw experience and seek each other again as it approaches the time to go home.
