Clone-A-Willy Vibrator Kit in Light
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 your or their penis needs to be fully erect - the harder, the better - use your favourite means to that end (a cock ring can help), and then insert the penis being replicated into the natural algae-based molding powder mix. Hold the tube steady for a minute or two, then remove yourself. 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.
