Knock boots strap on-style with Doc Johnson's Vac-U-Lock Ultra Harness Kit, a unisex all-you-need set comprising a harness and 6 inch vibrating dildo. Supercharge sexy times with the strap on and your lover, or use the vibe by itself for solo stimulation.

With an insertable length of 6.5 inches and a generous girth of 5.25 inches, this vibrating dildo is just the job for intermediate strap on enthusiasts. Boasting a skin-soft synthetic shaft, set of testicles, a super-strong suction cup base and a comfortable, adjustable harness for secure strap on and pegging play.

The Vac-U-Lock system is the absolute best way to secure any number of compatible toys. Simply popper the plug onto the inside of the harness and slide any of the Vac-U-Lock dongs or dildos on. The harness is made from strong and durable material, with a soft lining for comfort. The side straps adjust up to 50 inches for a perfect fit.

This product comes with a small amount of powder lube for smooth and easy attachment of Vac-U-Lock accessories. Be sure to coat the dildo's shaft with lashings of water-based lube before play to maximise your pleasure.

Please note: Men using the strap on should choose a Vac-U-Lock dildo without balls for maximum comfort and freedom. If you need to position the open crotch further forwards, try wearing the harness higher on the waist.
