Doc Johnson Vac U Lock Vibrating 8 UR3 Cock Set 1 Complete Strap On Kit

Vac-U-Lock Vibrating 8 UR3 Cock Set 1 combines a realistic 8-inch vibrating cock attachment with a secure harness system that transforms strap-on play into something far more satisfying. The Ultra Harness adjusts to fit waists up to 53 inches while the patented Vac-U-Lock system ensures your attachment stays firmly in place during action.

What It Does

The realistic UR3 material warms to body temperature as it slides against your partner's most sensitive areas, while internal vibrations travel through the entire shaft to create sensations you both feel. Unlike rigid silicone alternatives, this soft material flexes naturally with your movements, hitting the G-spot or prostate from angles that feel completely natural. The vibrating motor sends waves through the cock that your partner experiences as deep internal massage while you feel the vibrations transmitted back through the harness.

Each thrust builds arousal differently because the vibrations pulse against nerve endings inside your partner while creating feedback sensations against your clit or pubic area. Your partner's body responds with increased wetness and muscle tension as the soft head stimulates their deepest erogenous zones. When climax arrives, the combination of realistic texture and pulsing vibrations creates orgasms that start deep inside and radiate outward through their entire pelvic region.

Technical Specs

• 8-inch vibrating attachment with 6.5 inches insertable length
• Body-safe UR3 material that warms to skin temperature
• Battery-powered vibrator with simple push-button control
• Ultra Harness fits 28-53 inch waist measurements
• Includes powder dispenser for smooth attachment changes

How To Use It

Step into the harness and position the attachment against your pubic area, then tighten the straps until the base sits snugly against your body. Apply a light dusting of the included powder to the Vac-U-Lock connection before pressing the attachment firmly into place - you'll hear it click when properly secured. Turn on the vibrations and test the connection by gently tugging the shaft.

Start with shallow penetration to let your partner adjust to the girth, then gradually work deeper as their body opens up. The realistic material responds to your partner's natural lubrication by becoming even more slippery and flexible. Watch for signs of building arousal like increased breathing and muscle contractions, then vary your angle and speed to maintain steady pressure against their most responsive spots.

Who It Suits

Couples exploring strap-on play will appreciate how the adjustable harness accommodates different body types while the realistic material makes penetration more comfortable for receiving partners. The 8-inch length works well for those who enjoy deeper penetration without being overwhelming for beginners. Anyone frustrated with harnesses that shift during use will find the Vac-U-Lock system eliminates that problem completely. The vibrating feature adds satisfaction for both partners, making this particularly good for couples where both want to feel direct stimulation.

Expert Review from Our In-House Tester

The harness adjustment process impressed me immediately - the straps tightened evenly without pinching and the padding distributed pressure across my hips perfectly. When I pressed the Vac-U-Lock Vibrating 8 UR3 Cock Set 1 attachment into place, that satisfying click told me it was locked securely. The UR3 material felt surprisingly warm and flexible in my hands, nothing like the cold rigid toys I've used before. During penetration, the realistic texture created smooth entry while the vibrations buzzed against my clit through the harness base. My partner's response was immediate - deeper breathing and muscle contractions that I could feel transmitted back through the attachment. The motor stayed consistent even during rougher thrusting, and the harness never shifted position despite vigorous movement. When my partner reached climax, their body clenched around the realistic shaft while the vibrations kept pulsing, extending their peak far longer than usual. The powder dispenser made removal effortless afterward, and I'm already planning our next session with different techniques.
