The patented* Body Dock ® beginner harness takes strap-on play to a whole new level. It’s as simple as placing your favorite King Cock® Elite silicone dildo (or any suction cup dildo/vibrator**) onto the suction base. The Body Dock ® nylon straps can be easily adjusted to fit most body sizes and types. No rings. No clasps. No fuss. Press the suction cup of your favorite dildo or vibrator** against the concave suction base until ALL the air between them is released. The suction creates a super-strong vacuum between them, holding them tight as the action intensifies. To break the bond, simply lift the edge of the suction cup. Swapping out your favorite strap-on attachment has never been quicker or easier! *Patent pending **The coupling plate measures 3.4 inches (86 mm) in diameter and can accommodate any dildo with a suction cup with a diameter smaller than this size. • The easiest to use harness and strap system on the market • Patented Push & Play design works with most suction cups • Angled suction base helps keep dildo erect • The fitted body plate distributes pressure evenly, improving comfort • Heavy duty nylon straps and plastic adjusters • Easily adjusts to fit waists up to 54" (137 cm)
