50-year-old Yumi, possessing beauty that matches her youthful appearance, has been largely ignored by her husband in the bedroom. Seeking an adventurous affair, she joins a coupling circle and finds herself surrounded by two men for a thrilling new experience. When her sensitive ears are licked, her body instinctively writhes, unleashing her deep-seated submissive desires. As her sexy lingerie is stripped away, a surprisingly eager and passionate side emerges. Thoroughly pleasured by both men, she soaks the bed with sweat while reaching ultimate satisfaction through multiple creampie finishes.
