A 24-year-old office worker appears with beautiful facial features, full and well-shaped breasts, and a slim waist, embodying an ideal physique. As part of her regular care routine, her back is carefully massaged using plenty of oil. While seated, a breast massage is performed from behind, promoting deep relaxation. Though she initially shows a puzzled expression at the unexpected touch, the masseur explains how waste materials tend to accumulate in women's breasts, then proceeds to gently knead the mammary glands in circular motions along the ducts.
