This unbelievable 3 hour production was filmed from inside the Magic Mirror Box Car (which is a mobile studio with two-way mirror walls) at a beach in Shonan. The crew invites in several girls in from off the sand guaranteeing most of them anonymity by obscuring their faces. This anonymity and the offers of cash from the crew prompt several of these innocent girls to do away with their inhibitions and have a little AV fun. Some remove their clothes, others perform tekoki (hand jobs), a few perform oral (accepting the cumshots into their mouths at the end of a blowjob), and a few are even game for receiving masturbation and have full-on sex! These innocent girls perform like real porn stars and have a lot of fun while getting totally into performing for the camera (and some cash!). This is an absolute must-have for any fan of penis kenkyu (study of the penis) and amateur nanpa (picking up ordinary girls)!
