Unlike a traditional gag, this device keeps the mouth of the submissive sexual partner open and accessible. This rubber-coated stainless steel Jennings mouth spreader is perfect for use during oral sex. The black rubber coating ensures safe use and comfort, preventing the gag from slipping after insertion. This high-quality medical device is also used by dentists and doctors to keep the mouth open during procedures. The hinge features a ratchet function that securely holds the device open after insertion.
