"After turning 45, my husband's sex drive rapidly declined," says Morino Kiyoyo, a 50-year-old full-time housewife. She lives with her company employee husband of 25 years and their two sons. "He changes it up every day... ah, it's so embarrassing." While her husband's sex drive waned, hers seemed to increase in the opposite direction. Though she tried to relieve her mounting frustration and stress through masturbation, the limited environment and knowledge led to monotony. She finally gathered the courage to appear in an AV. "Since getting married, I've devoted myself to my husband, so I know nothing about eroticism. Please be kind." Despite her refined mannerisms and seemingly virtuous wife persona, how will Kiyoyo's first taste of infidelity be?
