Minako, a married woman who lives in a housing complex with her husband, was frustrated by her husband who was crazy about work because of the couple's activities. When I imagined a fierce SEX with my husband and comforted myself with masturbation, my eyes met a middle-aged man who was at the window open. Minako gradually opens her heart to this man who sincerely apologizes for not being offended. The two, who should never have met, have a relationship that makes them sweaty after witnessing this masturbation.
