A members-only, ultra-luxury men's salon located somewhere in Tokyo. - On the surface, it is a salon that offers healthy beauty treatments, but in reality it is a beauty salon where masochist male customers can feel like kings to their heart's content, with sadistic and perverted female staff providing sexual services. - There are four types of menus: King, Emperor, Demon King, and Overlord courses, and anal licking and handjobs and penis insertion are commonplace, and even if you want to ejaculate, you can't do it without permission from the female staff. - A heavenly beauty salon for male customers who want to be teased!
