How much do you love zippers?

So much! Dylan is a girl after our own heart: strong hot and tough as nails. This girl is the real deal - the kind who looks even more sexy after a scene glowing with that electric sexual energy. We bind Dylan in fuck-me position her gorgeous legs spread wide and arms bound behind her head. We position a Sybian so that it pushes down hard on her hot cunt. We clamp her nipples cane her feet and then it's time for a little predicament. We zipper Dylan along both sides of her torso and tie the string to a bowling ball which is tied to a bit in her mouth. Dylan has full control over the zipper as long as she can hold on to that bit with her teeth it stays on. But when it is too much to bear that ball is going to fall ripping the zipper off mercilessly. How many orgasms can she take until that ball comes down?
