Teach your sub a lesson with this wonderful sex toy from Spartacus! Black and Blue Ball Gag is a bondage device designed to keep your slave quiet and silent. It measures 2 inches in diameter and fits comfortable in the mouth. Due to the double D-ring buckle system the device is kept firmly wrapped around the sub's head. Try using this device together with some other BDSM accessory, for instance with a blindfold or wrist cuffs.
