A popular men's esthetic salon in Tokyo is gaining attention for its unique approach: estheticians intentionally expose their nipples to excite clients and improve blood circulation. This provocative technique is said to enhance the effectiveness of the treatment. While physical contact with female staff is allowed, client-to-client touching is strictly prohibited. However, once clients catch sight of the staff's prominent nipples and striking breasts, their excitement becomes uncontrollable. Many are drawn in by this allure, making it a key factor behind the salon's rising popularity.
