A sexually frustrated young wife from an affluent family living in the upscale Yamanote district. In front of the camera, she experiences her very first anal training session. Embarrassed and blushing, she confesses her husband must never see this—her shyness is adorable, her innocence captivating. Her dopamine-driven arousal is pushed further and further as she's penetrated by vibrators, dildos, and an electric drill, progressively stretching her for this first-time anal experience. A must-see performance by Kiyomi Fukada.
