This time's filming marks Aya Shiomi becoming a Dogma exclusive actress, her second year since joining them, and her 24th production overall. Exactly two years ago, she starred in a big project called "GONIN" featuring five bondage masters, but now that two years have passed, we wanted to see how much her SM skills have evolved. So, this time around, we asked three bondage experts (Naka Akira, Nagaokami Ren, Douzan Tetsushin) to perform nonstop intense bondage training sessions with her. Of course, this is another long feature at over three hours.
