This inflatable position pillow has a hollow center designed to anchor a super strong nylon strap, which then connects to a pair of heavy-duty metal cuffs. Once your subject is bent over the wedge-shaped pillow and strapped in, they are unable to escape while their hands are cuffed to the strap's heavy-duty O-ring centerpiece.The inflatable wedge allows you to explore and enjoy new positions you never thought were possible, all while your subject is comfortably restrained. The velvety-soft flocked vinyl feels great against your skin and it's made to play hard. Insert the nylon strap through the Position Master while it's deflated, then inflate the wedge and adjust the strap to fit snugly around your partner. The thick nylon strap features a plastic clip and buckle to prevent your lover from escaping, and the metal cuffs feature quick release levers just in case you lose the keys.
