One of the more serious of chastity devices is the Latowsky.

Thanks to Serious Male Bondage for the pictures.

REMINDER: The inventor of this device, Mario Latowski, is coming to New York to measure customers for custom male chastity belts. If you are interested in making a private measuring appointment and placing an order, please contact Mario directly at info@latowski.de. This is a unique and once-in-a-lifetime opportunity to meet Mario in person and be measured in person for the best fit. Click HERE for Mario’s website.
