Everything is clear - he tricked her into sex, but who really filmed it? He obviously filmed it with a different camera than the one he had in his hands! A hidden camera does not give this angle and quality of shooting! So the cameraman in the room with a professional camera and a camera in his hands just a farce.
There's not just one lover, there's a whole bunch of men. And they're fucking her up and down. The bitch really walks on her hands, or rather from one cock to another. Somebody's lucky to have a wife!
