Located close to the city center, this large-scale training center can accommodate over 300 people and is frequently used by major and mid-sized corporations for seminars and employee training, attracting numerous employees throughout the year. Adjacent to the facility is a dedicated lodging house designed to support participants. In the shared restrooms of this accommodation, two hidden cameras have been installed—one positioned directly above, the other at a diagonal side angle. These cameras have captured female employees sharing rooms masturbating in the toilet. The footage reveals raw, intimate moments, exposing the hidden desires that surface in the private gaps of daily life.
