A battery-powered motor sends vibrations through the entire shaft while the UR3 material warms against your partner's body and flexes with each thrust. You control the motor via the attached control pack while your partner feels pulsations targeting their G-spot or prostate. Friction from the realistic texture mimics natural skin, creating sensation that builds as you increase your pace and depth.
Arousal intensifies as vibrations work internally while you angle your thrusts to hit the most sensitive spots. Your partner's body responds against the harness as the motor's pulsations push them toward orgasm, with waves of pleasure arriving as you maintain rhythm and depth. Adam Eve Sextoys also stock vibrating strap-on options if you want to compare materials and attachment styles.
Measure your waist snugly where the harness will sit—the Ultra Harness adjusts to fit up to 53 inches, so check your size before ordering. A 6-inch penetrative length suits partners who enjoy moderate depth without extreme fullness; this is a practical mid-range size for most bodies. Choose based on comfort and what your partner actually enjoys, not on ego. Cockringshop specialises in products for men and couples, so if you're uncertain about size or fit, our staff can advise on what works best for your body type and experience level.
Attach the cock to the Vac-U-Lock plug using the included powder for a smooth, secure connection, then fasten the harness around your waist and between your legs. Position your partner comfortably and apply water-based lubricant generously to both the cock and their entrance. Begin with slow, gentle insertion while the vibrations are off, letting their body adjust to the girth before you activate the motor.
Once you're fully inside, switch on the vibrations and start with shallow, slow thrusts. Increase your pace as their body responds and they signal they're ready for deeper, faster movement. Angle your thrusts to target their most sensitive spots while you control the depth and rhythm that brings them toward climax. Rinse thoroughly with warm water after use.
| Feature | Specification | Benefit | Experience |
|---|---|---|---|
| UR3 Material | Non-phthalate realistic texture | Warms to body temperature and flexes naturally | Feels natural during penetration |
| Vibrating Motor | Battery-powered with control pack | Targets internal pleasure zones | Brings partners to powerful orgasm |
| Vac-U-Lock System | Secure suction attachment | Prevents slipping during thrusting | Allows confident vigorous play |
| Ultra Harness | Adjusts up to 53-inch waist | Distributes pressure evenly | Stays comfortable during long sessions |
This strap-on works best for couples who want vibrations added to penetrative play without losing realistic texture and authentic sensation. Beginners appreciate the secure Vac-U-Lock system that prevents slipping during vigorous thrusting, so you can focus on rhythm and depth rather than worrying about attachment failure. Partners who need more than penetration alone to reach orgasm will benefit from the motor's internal pulsations.
Skip this if you're seeking a strapless design—this system requires a harness worn around the waist and between the legs. If your partner prefers rigid, non-flexible penetration, a firmer material may suit them better. Those with very deep preferences may want to explore longer lengths available elsewhere in the strap-on range.

Tested and quality-checked Every new line we stock is hands-on tested before it ever goes live — we power it up, run it through its functions, and check it for safety and for how it actually performs. Overseas orders get a second function-test right before they ship, so a dead motor never reaches your door. Nothing is used for its intended purpose; it is checked, inspected, and re-boxed. What that means for you is simple: the unit you open is one we already know works. See how we test every product → |
Non-vibrating strap-ons rely purely on girth, depth, and thrusting rhythm for sensation, while this vibrating version adds a motor that targets internal pleasure zones without requiring faster movement. UR3 material flexes and warms, unlike rigid silicone or steel toys that offer no give. Strap On Me offers strapless and multi-motor options if you want alternatives to harness-based designs. Vibration adds a dimension that can help partners reach orgasm faster and more intensely, especially those who need clitoral or internal stimulation combined.
| Please read — safety first. Put the ring on before you are fully erect and use plenty of water-based lubricant so it slides on without pinching. Keep wear time short — no more than 20 minutes while you are getting used to it, and never fall asleep wearing one. Take it off straight away if you feel numbness, coldness, a change in colour, or any pain, as these mean blood flow has been cut off too far. Never share between partners without cleaning the item first or using a fresh condom. This information is general in nature only and is not medical or professional advice, and does not take your personal circumstances into account. Stop use and speak with a qualified medical professional if you have a relevant health condition, take medication for erectile function or blood pressure, or notice pain, numbness, or discolouration that does not settle. |
Pair this with Couples Intimacy Kits that include complementary items for shared pleasure during partnered play. Kits often feature items that enhance sensation for both partners—such as vibrators for external stimulation—so you can create layered pleasure that intensifies the experience beyond penetration alone. These combinations work well because they let you stimulate multiple pleasure zones at once.
