What it does

Slide the vibrating cock into the harness O-ring and the motor starts working with every thrust. Your partner feels the shaft's girth opening them up while vibrations massage their internal walls, building arousal that radiates through their entire pelvis. Orgasms hit harder when the motor amplifies every movement, leaving them shaking and breathless.

Meanwhile, you grind the harness base against your pubic mound where vibrations reach your clit during thrusting. Motor power creates tingling warmth that spreads from point of contact outward, making your muscles clench and release in waves. Both of you experience shared pleasure instead of one person being left out of physical sensation. Browse Strap On Me for other harness and attachment options.

Fit and sizing

Measure your waist where you'll wear the harness – the Ultra Harness adjusts from 28 to 53 inches, so it suits most body types. An 8-inch cock with 6.5 inches insertable works well for couples exploring strap-on play together without requiring extreme sizing. Position the harness so the base plate sits flat against your pubic mound; this is where vibrations will reach your clit during thrusting. Cockringshop specialises in products for men and couples, so if sizing feels tight or loose, our team can advise on fit before you buy.

How to use it

Secure the vibrating cock into the harness O-ring using the Vac-U-Lock system until it clicks firmly in place. Adjust the nylon straps around your waist and between your legs, positioning the base plate against your pubic mound. Test the motor settings before penetrating your partner to get comfortable with the vibration intensity.

Start with slow shallow thrusts to let them adjust to the girth, then increase depth and speed as arousal builds. Use grinding motions to maximise clit contact while the shaft massages their internal spots. When they start moaning and pushing back, you'll know the vibrations are driving them wild. Rinse the TPE shaft with warm water and mild soap after each session.

Feature breakdown

Feature Specification Benefit Experience
Vac-U-Lock System Patented locking mechanism Prevents slipping during vigorous fucking Complete confidence in attachment security
Realistic Head Detailed glans with corona ridge Creates entry sensation and G-spot targeting Partners feel authentic penetration experience

Who it suits

Couples exploring strap-on play will love how this system satisfies both partners instead of leaving one person out of the physical sensation. Pairs seeking extra stimulation beyond basic thrusting benefit from the multi-speed motor, and the realistic design appeals to anyone wanting lifelike penetration rather than a generic shape.

Skip this if you want something much larger – size queens may find 8 inches too moderate for their needs. Those preferring ultra-firm sex toys should look elsewhere, since TPE has some flex rather than rigid rigidity. If you need a sex toy that doesn't require batteries or charging, a non-vibrating strap-on will suit you better.

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

Standard strap-ons rely on thrusting motion alone to create sensation, leaving the wearer without direct stimulation. Vibrating versions add a motor that pulses through the harness base, so you experience shared pleasure with every movement instead of solo arousal. Pornhub Sextoys offers alternative vibrating options across different sizes and styles. Vibration intensity varies by model, so choosing between multi-speed and single-speed depends on whether you want control over the sensation or prefer consistent stimulation.

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. As porous materials can harbour bacteria, use a condom over them for sharing or easy clean-up. 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 strap-on with cock rings to maintain your partner's erection during play, intensifying sensation for both of you. Ring and harness work together during thrusting – the ring keeps blood flow strong while vibrations amplify pleasure through the harness base. Couples Intimacy Kits bundle compatible products designed to work together during partnered sessions, giving you everything needed without hunting for separate items.
