Sinopse

Two married couples struggle to cope with their sex lives. Kenji and Misaki, a seemingly happy married couple, lead a sexless life. Misaki, whose numerous seductions have been turned down by her husband Kenji, longs for a way to solve their sexless marriage. On the other hand, Shoko, a career oriented woman, is annoyed by the constant sexual attention she receives from her husband Yoshihiko, who believes fulfilling Shoko’s sexual needs is the greatest expression of love. When a chance meeting brings Kenji and Shoko together in a passionate affair, they suddenly find themselves re-examining their lives and struggling to understand what is truly important.
