Full instructions are included, but the basic process is simple, mix up the molding powder and water in a bowl, and pour into the tube that doubles as packaging until you're ready to use it. Since the penis you're using has to be fully erect - the harder, the better - use your favourite means to that end, and then insert, or have them insert their business into the molding powder mix. Hold the tube steady for a minute or two until it has set, then gently slide it off.
When you're ready, completely pour the combined contents of both jars of silicone mix into the mold. Next, position the vibe in the center of the filled mold and let it all set. What you'll be left with an exact copy of your favourite cock with all details intact AND vibration that will make the whole thing buzz for your perfect pleasure. Make sure to follow the very detailed instructions for best results. The appearance of your Clone-A-Willy will vary, deeding on the size and shape of your or their penis. Phthalate and latex free.
