When wide open isn't wide enough, The Fetish Fantasy Extreme Spider Gag is the gag to turn to. This gag has a sturdy steel 1.5 inch inner diameter ring with four curved metal 'legs' attached which helps to prevent the mouth from closing leaving your sub's mouth wide open for whatever you wish to place inside of it! The gag connects to an adjustable buckle fastening back strap which keeps it securely in place. Jaw ache beckons! One size fits the majority.
