We approached a friendly family on the street and, with the parents on the other side of the mirror in a special magic mirror studio, the eldest son confessed his virginity to his sisters! We proposed a sandwich threesome mission to the three, offering 1 million yen if you can take his virginity! We gave the eldest son a camera to film the aftermath of the family crossing the line! What was captured on the screen was shocking footage of the three people for whom incestuous sex had become a part of their daily lives...the content was voluminous! (Just as you'd expect from a sandwich)
