Vac-U-Lock 5 Realistic Cock Flesh With Strap-On

Strap-on play demands a secure, comfortable harness and realistic attachment that won't slip during use. The Vac-U-Lock 5 Realistic Cock Flesh with Strap-On delivers a medical-grade silicone cock with a revolutionary locking system and ultra-adjustable harness, giving you stability and control for intense penetrative experiences.

What it is

The Vac-U-Lock 5 Realistic Cock Flesh with Strap-On combines a lifelike silicone attachment with a precision locking mechanism designed for maximum stability during strap-on play. The realistic cock measures 5 inches long with proportional girth, crafted from body-safe medical-grade silicone that resists bacteria and remains hypoallergenic. The included harness adjusts to fit waists up to 53 inches, distributing weight evenly for comfort during extended use.

What sets this system apart is the Vac-U-Lock plug design, which allows you to swap attachments quickly without removing the harness. The secure locking mechanism ensures the cock stays firmly in place during penetration, eliminating the frustration of slippage or repositioning mid-scene.

How to use a strap on sextoy

Begin by adjusting the harness to fit snugly around your waist without restricting circulation. Apply the included powder to the Vac-U-Lock plug to ensure a smooth, secure connection. Insert the realistic cock into the harness attachment point and turn it firmly until you hear or feel the lock engage. Apply water-based lubricant generously to the cock and your partner's vagina or anus before insertion.

Start slowly, allowing your partner to adjust to the penetration depth and angle. Communicate continuously about comfort and pleasure levels throughout the scene. Experiment with different positions and thrusting rhythms to find what works best for both of you. Explore compatible products from the Pornhub Sextoys collection to enhance your strap-on play with additional sensations or restraints.

Care and storage

Clean the harness and realistic cock thoroughly with warm water and mild soap immediately after use. Allow both components to air dry completely before storage. Store in a cool, dry place away from direct sunlight and extreme temperatures. Never use silicone-based lubricants or oil-based products, as these degrade the silicone material. Keep the powder dispenser sealed and stored with the other components.

Mistress Athena's training notes

The Vac-U-Lock 5 Realistic Cock Flesh with Strap-On has become essential in my training practice. Precision engineering of the locking mechanism allows me absolute control—my submissives cannot predict when I might swap attachments mid-scene. The realistic texture combined with the harness's stability creates an overwhelming sensory experience that breaks through psychological defences quickly.

Quick-change capability transforms my sessions strategically. Starting with the 5-inch attachment, I observe my subject's physical and psychological responses before introducing variables. The harness's adjustability means I can position myself for maximum control and depth, regardless of a submissive's body type. Stability allows me to maintain consistent pressure while maintaining eye contact and psychological dominance.

My most effective training uses this system to establish protocol and obedience through physical conditioning. The realistic design heightens the psychological impact of submission—subjects experience authentic penetration without escape or negotiation. The powder dispenser ensures smooth transitions between scenes, maintaining the intensity of power exchange without logistical interruptions that break immersion.
