[Atelier Kobu] Mai to Rei video version

Overview： Mai-chan,the older sister with a slightly reserved personality,and Rei-chan,the naive younger sister,attempt their first image video shoot. They stand in front of the camera with cute smiles,but are confused by the increasingly provocative poses and costumes,and the shoot doesn't go smoothly. So they decide to stay behind to practice one-on-one with the director,but just practicing on the rodeo machine and massages is enough to get them soaking wet... They won't become "full-fledged idols" that way! As the director,I have to give them strict guidance so that they can do their job properly in the adult world!
