Doc Johnson Vac-U-Lock Platinum Supreme Harness with Plug brings professional-grade strap-on performance through patented vacuum attachment technology. This cushioned neoprene harness transforms any Vac-U-Lock compatible toy into a secure extension of your body for confident penetration play.
The vacuum plug creates an unbreakable seal between harness and attachment, eliminating the wobbling and slipping that ruins momentum during passionate sessions. Smooth neoprene wraps around your hips while pull-to-tighten straps distribute pressure evenly across your pelvis. The open crotch design allows direct access to your pussy or cock while the snap-front mechanism lets you swap attachments mid-session without removing the entire harness.
Your partner feels every thrust as a controlled penetration rather than awkward fumbling with loose toys. The secure attachment responds to your hip movements naturally, creating fluid motion that builds toward powerful climaxes. Heat from your body warms the neoprene material, making extended wear comfortable while you focus entirely on driving your partner to orgasm through deep rhythmic strokes.
Step into the harness and position the cushioned back against your lower spine before pulling the straps snug around your hips. Insert your chosen Vac-U-Lock attachment into the vacuum plug until you hear the seal click into place. The snap-front closure allows easy access for attachment changes without completely removing the harness from your body.
Start with shallow penetration to let your partner adjust to the toy's size before increasing depth and tempo. The vacuum seal maintains perfect alignment between your hip thrusts and the attachment's movement, letting you control exactly how deep and hard you penetrate. Listen for your partner's breathing changes and watch their body language to know when to shift angles or increase pressure for maximum satisfaction.
This harness works perfectly for couples exploring strap-on play where the wearer wants professional-level stability and comfort. The wide size range accommodates most body types while the cushioned design prevents the hip bruising common with cheaper harnesses. Advanced users appreciate the quick attachment swapping capability, while beginners benefit from the secure vacuum system that prevents embarrassing toy slippage during passionate moments.

The secure vacuum system and comfortable design support extended domination sessions where cheap equipment would fail or cause distraction.
Among our adult toy selection, this harness serves as the foundation piece that transforms individual dildos into complete strap-on systems. The Vac-U-Lock compatibility opens up dozens of attachment options, making this single harness work with multiple toys in your collection.
The vacuum seal impressed me immediately - no amount of aggressive thrusting could loosen the 8-inch realistic dildo I attached. The neoprene material felt substantial against my skin without being restrictive, and the cushioned back panel made a huge difference during our 45-minute session. My partner noticed the difference right away, commenting that the penetration felt much more natural and controlled compared to my old harness with loose O-rings. The snap-front design proved invaluable when we wanted to switch from the realistic dildo to a curved G-spot attachment halfway through. Instead of stopping to remove the entire harness, I simply unsnapped the front, swapped attachments, and we continued without losing momentum. The vacuum plug grabbed the new toy just as securely as the first. By the end, my hips felt fine despite the extended wear, and my partner had reached orgasm twice from the consistent angle and pressure this harness allowed me to maintain. The only cleanup required was a quick wipe-down of the neoprene and a thorough wash of the attachments.
