Haruka, who had come to the countryside as a bride, had sex with her husband almost every day, but her father-in-law could no longer contain his arousal. At that time, Haruka's father came to visit from Tokyo, his sights set on Haruka's body. Her father sneaks up on her at night, sneaking in when she's not looking, but her father-in-law finds out and rapes her, but her body, trained by the middle-aged man, is addicted to the pleasure of her father's persistent caresses, and the lustful young wife continues to have sex without her husband's knowledge.
