This strap-on pairs a curved silicone shaft with a contoured base that cups against the wearer's body. One end penetrates your partner while the other end curves inward to deliver vibration directly to the clitoris and vulva. Ten vibration modes let you dial in exactly the sensation you both want, from gentle pulses to stronger rhythms. Flex and movement during play keep the base in contact, meaning continuous external pleasure alongside penetration.
Made from body-safe silicone, it feels smooth and luxurious against skin. You'll find a traditional adjustable harness with a stretchy elastic waistband that holds everything securely, even during vigorous movement. Browse Strap On Me for other harness options and solo-use strap-ons. Charging happens via a magnetic USB connector—just snap it on and you're ready to go within the hour.
Measure your waist or hips—whichever is larger—at the point where you'll wear the harness. Most people wear it low on the hips. This set stretches up to 64 inches, suiting most adult bodies comfortably. Choose based on where you want the base to sit during penetration, not vanity sizing. A snug fit keeps the curved end in contact with the clitoris and vulva, so comfort and secure positioning matter far more than ego. Cockringshop specialises in products for men and couples, and our team can help you find the right fit if you're between sizes.
Put on the harness first, then adjust the waistband snugly around your hips or waist. Insert the shaft into your partner. Bend your knees slightly and angle your pelvis so the curved base stays pressed against their vulva. Start with a lower vibration mode and build intensity as sensation develops. Shallow thrusts let the base work on external nerve endings; deeper thrusts create fullness and G-spot contact.
During play, keep communicating—ask what feels good and adjust angle or speed if needed. Before and after use, rinse the silicone shaft and base with warm water and mild soap, then pat dry. Wipe the harness down with a damp cloth. The entire set is waterproof, so shower or bath play is possible, though you'll want to ensure the magnetic charging port stays dry between sessions.
| Feature | Specification | Benefit | Experience |

| Dual-ended vibration | 10 adjustable vibration modes | Both partners control their own pleasure | Shared intensity and customised sensation |
| Secure harness design | Adjustable elastic waistband to 64 inches | Stays in place even during rough play | Focus on sensation, not repositioning |
| Waterproof construction | Fully submersible silicone and polyester harness | Safe for shower and bath use | Spontaneous wet play without worry |
Couples who want shared pleasure where both partners get stimulation will love this. If you're new to strap-on play, the adjustable harness and ten vibration modes make it easy to find comfort and rhythm. Experienced couples will appreciate the dual sensation and secure fit for longer, more energetic sessions. Face-to-face positioning works well, so you get eye contact and closeness alongside penetration.
Skip this if you prefer non-penetrative play or have no interest in strap-on harnesses. Those seeking a smaller or firmer shaft might find the bulbous head too wide; likewise, if you need a longer insertable length, the 135mm maximum may not suit. People who dislike vibration should explore non-vibrating harness alternatives instead.

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 → |
Strap-on harnesses come in two main types: non-vibrating and vibrating. Non-vibrating versions rely on movement and positioning alone; vibrating models add motor-driven sensation on top of thrusting. A vibrating set gives you more layers of pleasure and lets you pause movement while sensation continues. Browse Adam Eve Sextoys to compare other vibrating and non-vibrating harness designs and find the right fit for your play style.
