There's a mysterious shop located in a building in central Tokyo, where seductive moans can be heard echoing from inside even during daytime. On the surface, it appears to be an ordinary massage parlor, but in reality, it's infamous for something far more illicit. By chance, we received a request from someone inside the shop to obtain secret footage, and we had no reason to refuse. As a result, we acquired unbelievable footage—its shocking content was beyond imagination.
