What it does

Wrap the leather harness snug around your waist and thighs, insert the tapered anal plug with plenty of lube, then attach the 7-inch cock to the Vac-U-Lock connection point. As you thrust into your partner, the plug shifts with each movement, creating waves of prostate pressure that build arousal differently than penetration alone. Your erection stays hard from the constant internal sensation while you watch your partner's body stretch around the realistic shaft.

Both partners feel every textured ridge and detail as friction builds. Orgasms hit harder when you're getting filled while fucking—powerful peaks that leave both of you trembling. Browse Strap On Me for other harness styles and attachment options. Unlike basic harnesses that shift during use, the non-slip leather stays locked in position no matter how aggressive your thrusting becomes.

  • Harness material: Genuine leather with adjustable straps and buckles

Fit and sizing

Step into the harness and adjust both the waist and thigh straps until the leather feels snug but comfortable—not pinching or binding when you move. At 49 inches maximum waist circumference, this harness suits most body types, though larger men should verify the expanded size fits comfortably before purchase. Cockringshop specialise in products for men and couples of all shapes and sizes. Start with the included anal plug before trying larger sex toys, and always prioritise comfort over ego. A harness that shifts during use will ruin the experience for both partners.

How to use it

Step into the harness and tighten the waist and thigh straps gradually until everything sits secure without digging in. Apply plenty of water-based lube to the tapered plug and insert it slowly, taking your time to adjust to the sensation. Attach your chosen cock to the Vac-U-Lock point and check that all buckles are fastened before beginning.

Start with shallow thrusts to get used to the dual sensation of penetrating while being filled. Listen to your partner's breathing and watch their body language to find the rhythm that makes them moan loudest. When you feel ready to ejaculate, the internal pressure will push you over the edge. After use, clean the PVC cock and plug thoroughly before storing.

Who it suits

Men who want to experience penetration while giving it will love this dual-sensation system. Couples exploring power dynamics benefit from the psychological thrill of role reversal, and experienced users appreciate the modular design that accepts different sized attachments. If you're new to anal play or strap-on use, take your time with the included plug and start slowly.

Skip this if you're not interested in receiving anal penetration yourself, or if a 49-inch maximum waist won't fit comfortably. Beginners should also consider whether they're ready for the added complexity of managing both sensations at once. There's no shame in starting with a simpler harness and building up to dual-sensation play.

Tested and quality-checked

Every new line we stock is inspected by hand before it goes live — we check the build, the finish, and the materials, and we confirm it is safe and fit for how it will be used. Nothing is used for its intended purpose; it is examined, checked, and re-boxed. What that means for you is simple: you receive a piece we have already vetted, not a guess off a supplier's pallet.

How it compares

Strap-on harnesses come in two main types: those designed purely for the wearer to penetrate a partner, and dual-sensation systems like this one that include internal plugs for the wearer's pleasure. Basic harnesses offer simplicity and focus, letting you concentrate entirely on your partner's experience. Dual-sensation harnesses add complexity but reward you with prostate stimulation and harder orgasms. Browse Pornhub Sextoys for other options in the category. Your choice depends on whether you want solo penetration play or mutual pleasure built into the same session.

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 harness with cock rings to intensify your erection and extend your stamina while you thrust—the ring's grip keeps blood in the shaft while the internal plug delivers prostate sensation. Couples exploring power exchange dynamics will find Couples Intimacy Kits offer complementary bondage and restraint gear that deepens role play. The combination of physical pleasure and psychological intensity creates powerful shared experiences.
