A happily married couple goes on a hot springs trip, but during the trip, I find myself drawn to my friend's husband—unlike my selfish spouse, he is thoughtful, gentle, and gives me incredibly satisfying sex. Dissatisfied with my husband's inconsiderate attitude and unsatisfying intimacy, I gradually become aware of my attraction to my friend's husband. Drunk and impaired in judgment, I end up having sex with him late at night. That indiscretion becomes the turning point I use to justify my actions to myself. From then on, I return once again to being a wife intoxicated by sex.
