FC2-PPV-4063180 is the official link to the corrupt delivery health service "Kitajima." Kitajima, who operates a delivery health business in the Kansai region, conducts interviews with women aged 18 to 50 and records videos of their actual intercourse training sessions. These videos will be uploaded one after another. The reason for such filming is simply to prevent employees from leaving the business by using the videos as leverage.
