What it is

This leather harness pairs a sturdy, adjustable frame with Doc Johnson's Vac-U-Lock mounting system. Black leather wraps around your waist and thighs, holding the included 7-inch dildo securely in place. Straps adjust from 30 to 49 inches, and the non-slip design keeps everything stable during use. The dildo itself is body-safe silicone with a realistic shape and 5.5 inches of insertable length.

What sets it apart is the Vac-U-Lock system: a proprietary socket that lets you swap dildo attachments in seconds without removing the harness. No tools, no fuss. You can switch sizes, textures, or styles mid-scene. See the full BDSM Australia range of Strap-On-Me to explore compatible attachments and harness styles.

How to use a strap on sextoy

Start by adjusting the harness straps to a snug, comfortable fit around your waist and upper thighs. The leather should feel secure but not restrictive. Align the included 7-inch dildo into the Vac-U-Lock socket until you hear or feel it click firmly into place. Apply generous amounts of water-based lubricant to the dildo and to your partner's opening, then proceed slowly with initial penetration, allowing time for adjustment.

Once play begins, the harness stays stable, leaving your hands free to touch, restrain, or guide your partner. You can swap dildo attachments mid-scene by simply pulling the current one from the socket and clicking a new one in—explore compatible options with Adam & Eve Sextoys for variety. Experiment with angle, depth, and rhythm to find what works for both of you. Always check in with your partner and stop if discomfort arises.

Specifications

Always use generous water-based lubricant, go slowly on initial penetration, and maintain clear communication with your partner throughout play. Safety first. This information is general in nature only and is not medical or professional advice; it does not account for your individual circumstances. Discontinue use immediately if you experience pain, numbness, discolouration, irritation or discomfort, and seek advice from a qualified medical professional if you have a relevant health condition or if symptoms persist.

Care and storage

Wipe the leather harness with a soft, damp cloth after use, then dry it thoroughly with a lint-free towel. For deeper cleaning, use a leather-specific cleaner following the product instructions. Wash the silicone dildo with warm water and antibacterial toy cleaner, rinse completely, and air-dry. Store both pieces in the provided protective bag, away from direct sunlight and heat, to preserve the leather's suppleness and the silicone's integrity.

Mistress Athena's training notes

This harness has become essential to my dominance practice. The leather's firm grip symbolizes my authority, while the Vac-U-Lock system lets me demonstrate absolute control—switching attachments mid-scene keeps my submissive perpetually uncertain and heightens their sensory focus. Psychological preparation matters more than the physical tool; my composure and command transform this into an instrument of surrender.

Each attachment choice serves a purpose in my training. Some submissives require gentle introduction; others crave intense stimulation. I meticulously select sizes and textures to match my objectives and their current thresholds. Blindfolding combined with unexpected attachment swaps deepens their submission and trust in my judgment.

The non-slip straps ensure stability during extended scenes, allowing me to maintain precision and control. My movements are calculated; each penetration is a lesson. Aftercare follows naturally once I've achieved the psychological state I'm training toward.
