Men's esthetics, which claim to be non-erotic but many have a gray impression. What is it actually like? We call a mature men's esthetician rumored to have a secret option in a room equipped with a miniature camera to investigate the truth. The ones we called were M-san, 34 years old, and T-san, 40 years old. Will they really let us do it when they are pressured with "Let me do it"? From a normal massage to a tense negotiation, to the ending that shows a tumultuous development. We secretly filmed everything and will publish it here. The work of mature men's esthetician girls who were not just gray, but completely black. Please take a good look.
