You provide the power, we will provide the pleasure! This adapter fits most standard reciprocating saws, so all you have to do is hook it up to your favorite power tool, and have endless penetration with incredible thrust. It even comes with a realistically textured dildo, so you are ready to go! The smooth head is tapered for easy insertion, and is a great standard size. The dildo has a vacuum seal base, so you can use it with Vac-U-Lock accessories, as well as most sex machines that have a Vac-U-Lock or vacuum seal component.
