58-year-old Kanako Narita is a businesswoman who once had a career as a ballerina. Due to injury and declining physical strength, she moved behind the scenes and devoted herself to teaching ballet. Starting with just one studio, her popularity led to increasing numbers of students, eventually expanding into managing multiple studios. She married a man she met through a network of entrepreneurs, building a happy family, but the demands of work and personal life caused growing emotional distance, leaving her stressed and overwhelmed. Through a dating app, she meets men to relieve both mental and physical tension. Though she once had a slender figure during her active years, age has transformed her into a voluptuous, bombshell milf. Her libido has intensified with time, turning her into a lustful woman who seeks sexual encounters outside her marriage during her limited free time. She indulges in these affairs secretly, careful to keep her double life hidden from those around her.
