This mouth hook allows you to keep your partner's mouth fully open for the duration of your bondage and sex session. With a fully open mouth you can feel free to give them a taste of your cock (for example). The mouth hook wraps around the head and the metallic hooks go into the corners of the mouth. The buckle-style closure is adjustable for a firm fit. The strap measures 13" in length. At its shortest it measures 9.5". The strap is made of leather.
