A married couple, both virgins before marriage—she a virgin bride, he a lifelong virgin husband. Their first time after marriage wasn't the erotic, passionate sex seen in adult videos, but rather ended in just five minutes, leaving her unsatisfied. Repeating this unfulfilling routine over time, she gradually becomes aware of relationships with other men and starts visiting infidelity websites, searching for a man who can give her the ideal sexual experience. This is the story of a married couple drifting into affairs.
