44-year-old Kaori Wakahayashi appears as the featured wife this time. She decided to participate because she wanted to "preserve her beauty and stay attractive for as long as possible." Her slender, flexible physique, maintained through Pilates, is mesmerizing to watch. Her body is extremely sensitive, becoming soaked with just the slightest stimulation. During her masturbation scene in the bath, she squirted so much that water pooled on the floor, reaching multiple intense orgasms. In the sex scenes, she experiences intense movements and consecutive climaxes, continuing until her body can no longer move. Her expressiveness and charm possess a powerful allure that captivates viewers.
