The patented* Comfy Body Dock® Strap-On Harness 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. 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.
