Finding a strap-on harness that fits securely, stays comfortable during extended wear, and works with multiple attachments is a real challenge. This harness solves all three: adjustable sizing, cushioned design, and Vac-U-Lock compatibility mean you can focus on control and sensation, not fit.
The Doc Johnson Vac-U-Lock Platinum Supreme Harness with Plug is a wearable strap-on system built for couples exploring penetrative play together. Made from neoprene and polyester, it combines durability with comfort through its cushioned support panel and open rear design. Adjustable straps let you dial in the perfect fit regardless of body type. The Vac-U-Lock socket accepts any compatible dildo, so you can swap attachments mid-scene without removing the harness.
What sets this harness apart is its focus on both stability and accessibility. The open crotch configuration keeps the wearer's genitals available for direct contact, while the secure Vac-U-Lock system ensures your chosen attachment stays firmly in place. See the full BDSM Australia range of Strap-On-Me harnesses to compare other styles and find your fit.
Start by adjusting the harness straps to fit snugly around your waist—snug enough to stay put, loose enough to breathe comfortably. Select your Vac-U-Lock dildo and push it firmly into the socket until it clicks and locks in place. Apply water-based lubricant generously to the attachment and your partner's opening. Position yourself so the open crotch design allows direct contact with your genitals if desired. Begin slowly, letting your partner adjust to the depth and pace before increasing intensity.
Communication is essential throughout. Check in frequently, adjust rhythm and depth based on your partner's feedback, and remember that the harness's open design means you can incorporate your own pleasure into the scene. The Vac-U-Lock system lets you change attachments mid-scene if you want to vary sensation or intensity. Explore the Strap On Dildos range to discover different sizes and textures that suit your preferences.
Wash the harness after every use with mild antibacterial soap and warm water, paying attention to all seams and straps. Rinse thoroughly and air dry completely in a well-ventilated space—never tumble dry or expose to direct heat. Store in a cool, dry location away from sunlight and extreme temperatures. Use only water-based lubricants; silicone and oil-based lubes can degrade the neoprene material over time.
Understanding position options and techniques can significantly enhance your experience with strap-on play. Read Strap On Positions for detailed guidance on angles, comfort, and how to maximise pleasure for both partners. Exploring different approaches helps you find what works best for your bodies and preferences.
This harness has become indispensable in my practice. Its adjustable straps allow me to achieve perfect positioning for absolute control, while the open crotch design lets me maintain direct sensory feedback throughout extended scenes. My submissives respond powerfully to the psychological weight of wearing me inside them—the vulnerability combined with my command creates profound surrender.
Precision is everything when I use this system. The Vac-U-Lock socket's reliability means I can focus entirely on reading my submissive's responses rather than worrying about mechanical failure. Switching between different-sized attachments mid-scene keeps them perpetually off-balance, never quite knowing what intensity or sensation comes next. This unpredictability deepens their submission.
What I've observed consistently is how the harness transforms power dynamics instantly. The moment I'm secured and positioned, my submissive's entire demeanour shifts. Their breathing changes, their eyes lower, their body language signals complete acceptance of my dominance. That psychological shift—from equal partner to willing submissive—is where the true power of this tool lies.
