Reiko dotes on her son. Before she knew it, they had fallen into a forbidden relationship. Reiko planned to thoroughly enjoy an intimate encounter with her son at a private hot spring resort and arrived there with him. After checking in, her son immediately reached out to have sex with Reiko, but she admonished him with a mother's face and led him to the private bath. The open atmosphere heightened the mood of the mother and son, and when her son kissed Reiko, they could no longer hold back and indulged in pleasure together. However, there was a man secretly filming them. This man had coincidentally ended up at the same inn and was Reiko's ex-boyfriend. He had just passed by Reiko and her son in the entrance hall, but Reiko hadn't noticed him. After a long bath, as Reiko walked down the hallway, the man called out to her. Reiko was suspicious upon hearing her name called, but when she realized that this man was her ex-boyfriend, he had already shown her pictures on his phone. Reiko's hand was grabbed by the man and taken to a secluded place as she panicked over her relationship with her son being exposed. Her body, heated from the previous act with her son, was sensitive, and she was forced into an unwanted climax by the man's caresses. She somehow made the man ejaculate through oral sex, but he took Reiko to his room and raped her. Reiko, who had been made to orgasm multiple times by the men, staggered back to her own room. After dinner, Reiko opened her body in response to her son's demands, but she felt unsatisfied with the act with her son. In the dead of night, Reiko got up alone and headed towards the men's room...
