What it does

The harness wraps around your hips and waist, positioning a dildo exactly where you need it for penetrating your partner. You insert your chosen Vac-U-Lock-compatible dildo into the included plug until you hear the suction click—that's your signal the attachment is locked firm. Every thrust you make transfers directly through the harness to the mounted cock. Your partner feels the controlled depth and angle as you drive it inside them, while the secure mounting means no wobbling or slipping that breaks rhythm.

Quality leather straps sit snug against your body, and the strategic crotch opening lets your natural anatomy remain accessible underneath. Your hands stay free to grab their hips, squeeze their ass, or stimulate their clit as you fuck them. You maintain complete control over pace and intensity while building toward their orgasm. Pornhub Sextoys stocks a range of compatible attachments to pair with this harness.

Fit and sizing

Measure around your hips and waist at the point where you'd normally wear a belt. The adjustable straps on this harness accommodate waists up to 53 inches, so check your measurement against that figure. Most people find it sits comfortably across the hip bones and lower abdomen. A snug fit is essential—loose straps cause shifting during thrusting, while over-tightening cuts off circulation and kills comfort. Buckle it so you can fit one finger underneath. Cockringshop specialise in products for men and couples, so if you're unsure about your fit, get in touch and we'll help you choose.

How to use it

Buckle the waist straps around your hips and adjust until snug but not tight—it shouldn't shift during movement. Insert your chosen Vac-U-Lock dildo into the plug until you hear the suction click that confirms a secure seal. Position yourself between your partner's legs and guide the attached cock to their entrance. Start with shallow thrusts to let them adjust to the size, then drive deeper as they relax into it.

Your hip movements control the rhythm naturally. Watch their face and listen to their breathing to gauge when they want it harder and faster. The rock-solid attachment means you can pound them as aggressively as they crave without losing connection. After use, clean the harness with warm soapy water and air dry it completely before storing.

Feature breakdown

Feature Specification Benefit Experience
Vac-U-Lock System Airtight suction mounting Eliminates dildo slippage during fucking Maintains rhythm without interruption

Who it suits

Couples exploring power exchange dynamics will love how this harness shifts control to the wearer. Straight couples, queer couples, and mixed-gender partners all benefit from the unisex design. If you want to fuck your partner with confidence and stamina without losing connection, this harness belongs in your collection. Beginners appreciate the simple buckle system, while experienced users love the rock-solid attachment security that handles aggressive play.

Skip this if you prefer strapless designs or if your waist exceeds 53 inches—it won't adjust to fit you comfortably. If you're not interested in power exchange or penetrative play, this isn't the right tool for you.

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 →

How it compares

Leather harnesses like this one offer a commanding feel and direct control, but they're rigid and don't flex. Strap On Me offers strapless and motorised alternatives that work differently—strapless models free you from wearing anything at all, while vibrating versions add clitoral stimulation to the experience. Choose a leather harness if you want the weight and structure of a traditional strap-on, or consider a strapless design if you prefer hands-free penetration without wearing a harness.

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.

What you can use it with

Pair this harness with Anal Sex Toys for versatile penetration—the open crotch design means you can access both holes during a scene. A complementary cock ring worn underneath can intensify sensation for the wearer and extend stamina. Compatible Vac-U-Lock dildos in different sizes and shapes let you match the attachment to your partner's preference each time.
