[Enjoy in 4K Ultra High Quality] This time's masochistic woman volunteer is a 23-year-old caregiver. Since high school, she was repeatedly molested on her daily commute train, but instead of feeling disgusted, she realized she harbored a deep, perverted masochistic desire within herself. After graduating from junior college, she started working at a care facility and began an affair with her superior, a care manager. He was extremely dominant, repeatedly training and dominating her through sadistic play, making her completely addicted to the relationship. However, when her boss was transferred and the sessions abruptly ended, she fell into constant masturbation, living each day filled with pent-up sexual frustration.
