Dual penetration can feel overwhelming without the right tool—uneven pressure, discomfort, or poor fit often ruins the experience. Vac-U-Lock Code Black Double Penetrator The Naturals solves this with two precisely sized shafts and body-safe silicone, delivering balanced simultaneous stimulation you can control.
Vac-U-Lock Code Black Double Penetrator The Naturals is a dual-shaft dildo engineered for simultaneous penetration of multiple erogenous zones. Each shaft is sized and shaped differently—the larger at 5.2 inches with 1.5-inch width, the smaller at 4.6 inches with 1-inch width—so you experience varied sensations at once. The body is carved from premium phthalate-free silicone, smooth and non-porous, making it hygienic and simple to clean. Its innovative Vac-U-Lock base lets you attach it securely to harnesses, sex machines, and other accessories, opening up hands-free and partnered play options.
What sets this double penetrator apart is its balance of intensity and control. The dual-shaft design isn't just wider—it's thoughtfully proportioned so both insertions feel deliberate and manageable. See the full BDSM Australia range of Strap-On-Me harnesses to pair with this toy for maximum versatility.
Start by applying generous water-based lubricant to both shafts and the insertion areas. Insert the smaller shaft first, allowing your body time to adjust, then gradually introduce the larger shaft. Go slowly—dual penetration requires patience and communication with yourself or your partner. Find the angle and depth that feel right, and remember you can adjust positioning at any moment.
Once comfortable, experiment with different angles, thrusting patterns, and speeds to discover what intensifies sensation. If using a harness, the Vac-U-Lock base locks firmly in place for hands-free exploration and partnered play. Pair this with toys from the Adam & Eve Sextoys range for layered sensations, or combine with bondage or restraints for deeper psychological intensity.
Wash thoroughly with mild soap and warm water immediately after use, paying attention to both shaft bases and the Vac-U-Lock connection. Rinse completely and air dry on a clean towel. Store in a cool, dry place away from direct sunlight and extreme temperatures. Keep away from silicone-based lubricants, which can degrade the material over time.
Understanding dual penetration play—how to prepare, what positions work best, and how to communicate during use—takes knowledge and confidence. Revealing The Strap Ons For Couples You Need To Buy offers practical guidance on selecting and using penetrative toys with a partner.
This double penetrator has become indispensable in my practice. The dual shafts create a specific sensation of fullness that breaks through resistance quickly. Watching a submissive struggle with the dual penetration—their breathing shift, the involuntary muscle tension—reveals exactly where their psychological limits sit. Control over depth and rhythm becomes a tool for demonstrating absolute dominance.
My submissives respond viscerally to the varying shaft sizes. The smaller shaft enters first, creating a false sense of manageable intensity, then the larger shaft compounds the sensation unexpectedly. That moment of surprise, when they realise the full scope of what's inside them, is where surrender happens. I use this strategically in training protocols.
The Vac-U-Lock base allows me to secure this toy in a harness and maintain my hands for other forms of control—impact play, sensory denial, or simply holding their body still while they process the dual stimulation. This multitasking capability deepens the power exchange. Some submissives require multiple scenes to acclimate; others respond with immediate obedience once they understand my intent.
