元パパ活相手とのヒミツのSEX～義父からの貞淑試験～

Kanna is visiting her fiancé Mikiya's family before their wedding. When she meets Mikiya's father, she realizes that he is the man she once met as a sugar-daddy and who had dominated her sexually. Mikiya gets drunk at dinner, and falls asleep. Her father-in-law, who knows Kanna's past identity, shows her a sex video he had taken of her and tells her that he will test her to see if she can become a proper wife for Mikiya, his precious son.
