Yoko is a housewife who's frustrated by her husband's lack of virility. She finds solace in erotic daydreams, the ministrations of a condom salesman, a threesome with her friend and her dentist husband, the attention of her husband's virginal brother, and, eventually, the partner-swapping lifestyle.
