Like its new companion, the Red, and the first two pioneering Flip Holes, all you need do is flip the Silver open and lube up the interior. Then slide in for the suction stimulation of a lifetime! Like sensual crystals, the edges inside are "sharp". They won't cut you but they are designed to provoke tingles and tight squeezes on your member. Take your time pushing in and out, exploring the different zones inside the Silver: The "Cross Head" that tickles your head; the "Winding Rib" section that will make you twist as you enter; "Wing Edge" gives you a tight squeeze from the side, while "Shaky Wave" and "Star Solid" provide up-and-down variations on stark, stimulating curves. A geometrically crafted masterpiece of stimulating contours: The Flip Hole Silver proves there can be something more precious than gold after all.
