Unlike a traditional gag, this device keeps the mouth of the submissive partner open and accessible. This rubber-coated stainless steel Jennings mouth spreader is perfect for use during oral sex. The black rubber coating ensures a secure fit 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 spreader open after insertion.
