Inserting a butt plug can feel intimidating without the right tool and technique. The Vac-U-Lock UR3 Hung Cock combines substantial size with harness compatibility, giving you control and confidence during intense BDSM scenes.
The Vac-U-Lock UR3 Hung Cock is a realistic silicone dildo built for serious BDSM play. At 8 inches long with a 2-inch diameter, it delivers substantial penetrative sensation with anatomical detail—pronounced veining and natural curvature make it feel authentic. The base features Vac-U-Lock compatibility, letting you attach it securely to harness systems for hands-free control during scenes.
What sets this apart from standard dildos is its integration with harness technology. You get multiple mounting positions and the ability to adjust depth and angle without holding it. See the full BDSM Australia range of Butt Plugs to compare harness-compatible options.
Start by applying water-based lubricant generously to both the toy and your anus. Attach the Vac-U-Lock UR3 Hung Cock securely to your harness system. Insert slowly, allowing your body time to adjust to the size. Control depth and angle as you move, maintaining steady pressure and checking in with yourself throughout.
Advanced users can experiment with different mounting positions and combine this toy with restraint systems for deeper power exchange. Pairing it with Butt Tails adds visual impact during domination scenes. Always use water-based lubricant only, as silicone-based products can degrade the material over time.
Clean the toy thoroughly with mild antibacterial soap and warm water after each use. Rinse completely and air dry before storing. Keep it in the included protective bag in a cool, dry place away from direct sunlight. Store away from other silicone toys to prevent material degradation. Use only water-based lubricants to maintain the silicone's integrity.
Understanding your preferences before choosing a butt plug makes the experience more enjoyable. Read How To Choose A Butt Plug for detailed guidance on size, material, and technique. Knowledge builds confidence, and confidence transforms your scenes.
This cock has become indispensable in my dungeon. Its substantial girth and length command absolute respect from my submissives. I use it strategically during protocol training—the anticipation of insertion becomes a powerful psychological tool. Watching a slave process what's coming, their breathing shift, their body tense: that's where real control lives. Physical sensation matters less than mental surrender.
My most effective technique begins with verbal preparation. I describe exactly what will happen, how deep they'll take it, what surrender looks like. Blindfolding amplifies the psychological impact. The Vac-U-Lock system lets me position it at angles that maximize their sense of helplessness. Some slaves require gradual introduction; others need the shock of immediate intensity. Both approaches work when you understand your submissive's psychology.
What I've learned is this: the toy itself is merely the instrument. The real power comes from control, timing, and understanding exactly where your slave's breaking point lies. This cock becomes a symbol of my dominance—not just a physical object, but a statement of absolute authority. Used correctly, it transforms a scene from mere sensation into genuine submission.
