NO RINGS, NO SNAPS, NO HASSLE! The patented Body Dock Universal Harness System takes strap-on play to a whole new level! It’s as simple as attaching your favorite King Cock Elite silicone dildo (or any dildo/vibrator with a suction cup*) to the suction dock. The Body Dock nylon straps can be easily adjusted to fit most sizes and body types. *The docking plate measures 8.6 cm in diameter and can accommodate any dildo with a suction cup with a diameter smaller than this size.
