You most likely know this device as something doctors and dentists use to keep their patients mouths wide open. However, you can use this same device on your partner to keep their mouth open for more devious and playful purposes. The gag uses a hinge with a ratcheting feature, holding it securely in place.
These ankle restraints use a belt buckle locking system, but you can add more security by placing a padlock through the buckle. Now you can be sure that your partner won't be able to remove them without the key. There's a D-ring so you can attach the cuffs to each other (using a quicklink) or to other bondage gear.
