About Vac-U-Lock Vibrating 6" UR3 Cock with Strap-On Kit

The UR3 cock vibrates along its entire length through a powerful internal motor, sending stimulation through both the wearer and receiver simultaneously. The vibration intensity adjusts to match your preferences, from gentle pulses to more intense sensations. This dual-sensation approach transforms partnered play by creating shared pleasure rather than one-directional penetration.

The UR3 material replicates skin texture and appearance with remarkable accuracy while remaining phthalate-free and body-safe. The realistic flesh tone and lifelike surface add genuine intimacy that rigid materials cannot achieve. For those interested in expanding their collection, Adultsmart's clitoral pulsators offer complementary stimulation options.

How to Use Vac-U-Lock Vibrating 6" UR3 Cock with Strap-On Kit

Basic Use

1. Attach the dildo to the harness using the Vac-U-Lock system by twisting firmly until fully seated. The connection should feel stable and immovable before proceeding.
2. Step into the harness and adjust the straps to fit snugly around your waist and thighs. The fit should be secure but not restrictive, allowing comfortable movement.
3. Apply water-based lubricant generously to the dildo and the receiving partner's opening. This ensures smooth, comfortable penetration and enhances the realistic sensation.
4. Position yourself and your partner comfortably before beginning. Take time to communicate about pace, depth, and sensation preferences.
5. Activate the vibration by pressing the control button, starting at a lower setting to gauge comfort. Adjust intensity based on feedback from both partners.
6. After use, remove the dildo from the harness by twisting counterclockwise. Clean both components separately before storing.

Extended Use

Combining this vibrating dildo with nipple suction toys creates layered stimulation that many find more intense than penetration alone. The wearer can experience dual sensations while the receiving partner focuses on the internal vibrations. Alternating vibration intensity throughout a session builds arousal differently than steady settings, allowing you to discover what rhythm feels most pleasurable.

Care Instructions

After each use, clean the dildo with warm water and mild soap, paying special attention to the Vac-U-Lock connection point where moisture can accumulate. The UR3 material is not waterproof, so avoid submerging or spraying with water. Allow both the dildo and harness to air dry completely before storing them separately in a cool, dry location away from direct sunlight.

Materials and Safety

The UR3 material construction is phthalate-free and body-safe for internal use, meeting safety standards for intimate contact. Non-porous UR3 resists bacterial growth and maintains its realistic texture through repeated use without degradation. The durable material withstands vibration stress without cracking or developing surface damage, ensuring years of reliable performance. Water-based lubricants are fully compatible with this material and recommended for optimal comfort.

Who Is Vac-U-Lock Vibrating 6" UR3 Cock with Strap-On Kit For?

This kit suits couples exploring penetrative play together, whether heterosexual, lesbian, or any partnering preference seeking realistic sensation. Those new to strap-on experiences benefit from the included harness and straightforward Vac-U-Lock system, while experienced users appreciate the vibration feature as an upgrade. Solo players find the hands-free potential valuable for self-exploration, and the realistic design appeals to anyone prioritizing authentic sensation over fantasy aesthetics.

Why Vac-U-Lock Vibrating 6" UR3 Cock with Strap-On Kit Matters

For couples who have felt that strap-on play lacks the sensation feedback of penetration with a biological penis, the dual-sensation vibration changes what shared pleasure can feel like. The wearer experiences vibrations directly from the motor while the receiver feels those same vibrations transmitted through the shaft—creating synchronized sensation instead of one partner leading and the other following. For those frustrated by harnesses that shift during use or dildos that feel unstable, the Vac-U-Lock system delivers security that allows focus on pleasure rather than constant adjustment. The realistic UR3 material adds psychological immersion that fantasy colors or exaggerated shapes cannot provide. For people hesitant about strap-on exploration, having the complete kit with a comfortable harness removes the barrier of sourcing components separately. The 6-inch length strikes a balance between satisfying depth and approachable girth, making this kit accessible for beginners while remaining engaging for experienced players seeking new sensations.
