A device made to teach our trainees patience and self-control, as a rash decision can result in quite a lot of pain~ The trainees are restrained in a metal frame with their legs spread wide apart. Two metal rings are located within their hand’s reach and wheel with leathery straps is placed in front of their exposed crotch, that starts spinning once the training begins. Slowly at first, the gentle impact of the belts causes a quite pleasurable experience. Over the course of a few minutes, the wheel spins up to considerable speed, turning the gentle claps into a painful whip. The trainees may control the speed of the wheel by gripping either of the two metal handles. The stronger the handles are gripped, the more the wheel slows down – though causing the wheel to stop completely is a quite strenuous task that needs a lot of force. The handles, however, heat up whenever they’re being touched, making them become unbearably hot eventually. The goal of this test is to endure a light slapping while repeatedly gripping each ring for only a short time. After 45 minutes of training, the wheel automatically stops and the trainees are released~
