25-year-old Mikako Horii, a cute and mischievous Kansai-speaking office lady, ends up in an unexpected shared room with her ordinary married boss. Despite being at work, they skip their duties and indulge in non-stop affection. Mikako's charm is irresistible—she turns the middle-aged man into a complete pushover. With a strong libido, she constantly craves more. Her sweat-soaked stockings and voluptuous, shapely ass are irresistible. Her shirt is drenched in sweat, giving off a sexy scent. Pressed closely against him, her flirtatious Kansai dialect drives him wild with desire. He can't resist any longer. The thrill of experiencing a young body he could never have with his wife makes his heart race. Even if getting caught could destroy his life, he can't resist the thrilling sensation. He forgets everything and just wants to keep having sex over and over again.
