The patented* Comfy Body Dock Strap-On Harness takes strap-on play to a whole new level! Its 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. No Rings. No Snaps. No Hassle. Push the suction cup of your favorite dildo or vibrator** against the concaved suction dock until ALL of the air between them is released. The suction creates a super-strong vacuum between them & holds tight while the action heats up! To break the bond, simply lift the edge of the suction cup. Changing your favorite strap-on accessory has never been faster or easier! *Patent Pending **The docking plate measures 3.4 in. (86 mm.) in diameter and can accommodate any dildo with a suction cup with a diameter smaller than this size.
