Slide down the cone of the Grip and feel the stretch build with every inch until you pop over the widest point and your lips settle onto a purposefully thick neck. It holds you open and locks the plug in place, so you can wear it and work it with no depth to manage. Ride it, pop it out, and take it again, until your hole gives up its grip a little more each time. Choose your starting size, then work your way up the range.
