From our CCM Graphics Extreme Restraints Online Bondage Store we feature the "Spring Loaded Mouth Gag" which is arguably the most sadistic mouth gag available today. You put it in your submissives mouth and then when they try to speak the spring loaded trap opens as much as their mouth opens. And it won't close until you release it. Whenever they try to talk, it opens wider until she or he learns their lesson. Click on photo to see larger image.
