A sex training institute that is said to always exist in red-light districts. It is said that for women who set foot in the world of sex industry for the first time, they teach everything from customer service etiquette to practical instruction. This time, with the cooperation of a certain sex shop manager, we succeeded in a top-secret shoot! I'm going to do it to the point where I don't have to teach a nervous amateur. SEX of maidens and ordinary housewives who are not yet familiar with the industry. [* There is some disturbance in the image and sound]
