What it is

This strap-on dildo pairs Doc Johnson's signature Vac-U-Lock mounting system with realistic UR3 silicone construction. Eight inches long with a flesh tone finish, it delivers substantial penetration while the harness keeps everything secure and stable during movement. The UR3 material mimics natural skin texture, offering a sensory experience that feels authentic without sacrificing durability or safety.

What sets this apart is the engineering behind the connection. The Vac-U-Lock system creates a tight seal that prevents slippage, letting you focus on pleasure and control rather than adjustment. See the full BDSM Australia range of Strap-On-Me products for other harness and attachment options.

Key features

  • Realistic texture: UR3 silicone creates lifelike sensations that respond to touch and temperature.

  • Adjustable harness: Ultra Harness fits waists up to 53 inches with multiple strap adjustments for comfort.
  • Easy maintenance: Included powder dispenser keeps the silicone soft and supple between uses.

Specifications

  • Overall length: 8 inches with proportional width for substantial yet comfortable penetration.
  • Material: 100% body-safe UR3 silicone, phthalate-free and hypoallergenic.
  • Harness system: Vac-U-Lock mounting with manual operation—no power required.
  • Harness sizing: Ultra Harness adjusts to fit waists up to 53 inches.
  • Box contents: Strap-on dildo, Ultra Harness, powder maintenance dispenser, and detailed instructions.

How to use a strap on sextoy

Begin by securing the dildo firmly into the Vac-U-Lock harness—you'll feel it lock into place. Adjust all harness straps around your waist and thighs for a snug, comfortable fit that won't shift. Apply generous amounts of water-based lubricant to the dildo and your partner's opening. Position yourself carefully and enter slowly, checking in with your partner about comfort before increasing depth or pace.

Communication remains essential throughout. Vary your angle and speed based on feedback, and experiment with different positions to discover what feels best for both of you. Many users find that exploring options within the Adam & Eve Sextoys range opens up additional possibilities for couples play. Stop immediately if either partner experiences discomfort, and always prioritize mutual pleasure and consent.

Always use plenty of water-based lubricant, go slowly during initial penetration, clean the dildo thoroughly after each use, and never share the harness or dildo without proper cleaning between partners. 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

Wash the dildo and harness with warm water and toy cleaner after each use. Pat dry thoroughly before applying the included powder to maintain the silicone's softness. Store the dildo separately from other silicone toys to prevent material degradation. Keep the harness in a cool, dry place away from direct sunlight. Inspect both pieces regularly for any signs of wear or damage.

Mistress Athena's training notes

This cock's realistic texture and substantial girth make it an invaluable tool in my practice. Submissives respond immediately to its appearance—the psychological impact precedes the physical sensation. My control over depth, speed, and angle keeps them entirely dependent on my decisions, which is precisely where they need to be.

The Vac-U-Lock system's reliability allows me to focus entirely on my submissive's reactions rather than worrying about technical failure. I've observed that the 8-inch length intimidates without overwhelming most trainees, creating that perfect balance between challenge and achievability. Positioning varies based on what I wish to reinforce—some scenes demand dominance from above, others require more intimate proximity.

Preparation is key. I introduce this tool gradually, using sensory play and denial to heighten anticipation before deployment. Some submissives require extensive warm-up; others respond instantly to the visual threat alone. The material's warmth and give create an almost living quality that generic toys simply cannot match, deepening the psychological surrender.
