The Fucking Adapter is a high-quality, affordable sex tool. It features an electroplated, super-smooth surface. It fits all Vac-U-Lock dildos, so you are not limited to a specific size. It can be used for both anal and vaginal penetration. The Fucking Adapter works with most reciprocating saws or similar saws. The adapter quickly adjusts the saw to fit the dildo. For some saws, you may need to remove the footplate to attach the adapter. Note: The Fucking Adapter does not work with the new Ryobi saws that have a quick-release feature. The older style saws are fine, as they secure the blade with an Allen screw. The adapter is 5 1/2 inches long and 1 inch wide.
