A man and a woman meet again at a class reunion. It seems that they are both married, and their dissatisfaction with their spouses and sexual frustrations are united, leading them to a love hotel. Their pent-up sexual desires and memory boosters destroy the married couple's sense of ethics, and they reveal to each other the lewd adult selves they have become since back then. The eroticism is exceptional, precisely because they know what it was like to be adolescents.
