You may have asked yourself before about pay per view cams. These are basically videochat sites where you sign up in order to video chat in live private show with one of the webcam girls / performers of your choice. Once you enter the private room of the selected performer you are being charge by the minute. So the website system or software calculates the exact time you've spent in the private room and charges you accordingly. This is what pay per view cams are really all about.
