Harness play can feel complicated and restrictive. The Vac-U-Lock EZ Rider Thong Velvet Harness with Plug Black strips away that friction—soft velvet, quick toy swaps, and a design that delivers sensation to both partners make this your go-to for confident, comfortable strap-on exploration.
The Vac-U-Lock EZ Rider Thong Velvet Harness with Plug Black is a thong-style harness built for hands-free penetration play. Its soft black velvet exterior wraps around your body with adjustable straps, while the integrated Vac-U-Lock plug sits front-and-centre for quick attachment of compatible dildos. The thong cut means the wearer gets direct stimulation during use—this harness works for both partners, not just the one wearing it.
What sets this apart is the Vac-U-Lock system: press your chosen dildo onto the plug, and it locks in place instantly. No fiddling, no fumbling. The velvet feels luxurious against skin, and the diamond texture adds subtle sensory detail. See the full BDSM Australia range of Strap-On-Me harnesses and attachments to build your collection around this core piece.
Start by adjusting the waist and leg straps for a snug, comfortable fit—you should be able to fit one finger between the harness and your skin. Select your dildo and align it with the Vac-U-Lock plug. Press firmly until you hear or feel a click; the toy is now locked in place. Apply water-based lubricant generously to both the attachment point and the toy itself before penetration.
During play, the thong design means both partners receive stimulation. Start slowly, allowing time for comfort and arousal to build. The Vac-U-Lock system lets you swap attachments between scenes or mid-scene if desired—simply press the release button and swap. Explore different sensations and angles by choosing from the range of Strap On Dildos available in various sizes, textures, and materials to match your preferences.
Machine wash the harness in cold water on a gentle cycle, then air dry completely before storage. Clean the Vac-U-Lock plug with a toy cleaner or warm soapy water, and dry thoroughly. Store in the included bag in a cool, dry place away from direct sunlight and heat. Avoid harsh chemicals or abrasive scrubbing, which can damage the velvet finish.
Understanding harness fit and positioning takes practice. Read On Your Back for detailed guidance on comfort, angles, and technique. The more you know about your body and your partner's preferences, the more confident and enjoyable your strap-on play becomes.
This harness sits at the centre of my control practice. The thong design means my submissive feels my presence with every movement—there's no hiding, no escape into distraction. When I select an attachment, I'm choosing their next lesson. Smaller dildos teach obedience; larger ones test their limits and reinforce their surrender.
The Vac-U-Lock system gives me extraordinary power during a scene. My submissive never knows which attachment comes next. I watch their breathing shift as I approach with a new toy, their pupils dilate when uncertainty peaks. That psychological edge—the not-knowing—breaks down resistance faster than size ever could.
Velvet against their skin creates a sensory contrast I exploit ruthlessly. Soft material, firm control. My hand on the harness becomes an extension of absolute authority. Their body responds before their mind catches up, and that's where real training happens—in that gap between thought and reaction. This harness closes that gap entirely.
