SVDVD-625 Daruma-san fell down when he installed the Big Bang rotor.

Amateur women only! The biggest obstacle in this "Daruma-san ga Koronda" project is putting on a Big Bang vibrator to start the game! After the demon's call, the switch is flipped, and the vibrator inserted into the vagina vibrates violently. Which woman will become the victim of this monster toy with 86 times the voltage and receive a punishment game of sex? Will she be able to shake off the demon's erotic pranks and receive the prize money?
