What it does
Both attachments sit snugly against your partner's body, filling the vagina and rectum at once. Velvet fabric glides across skin as you thrust, creating friction and warmth that spreads through the pelvic region. Adjustable straps hold everything in place during vigorous movement without shifting, so you stay in control of depth and angle with each stroke.
Dual penetration creates overwhelming fullness that builds arousal faster than single entry alone. Your partner's muscles contract around both attachments, generating tighter sensations and deeper pressure waves. Orgasms arrive with stronger contractions as both entry points receive consistent contact, producing climaxes that shake through the entire pelvic region. Browse Pornhub Sextoys for complementary products that pair well with strap-on play.

Fit and sizing
Measure your waist at the narrowest point and your hips at the fullest. This harness fits waist sizes from 28 to 48 inches, so check your measurements before ordering. Cockringshop specialise in products for men and couples, and we stock a range of harnesses to suit different body types. Choose a size that sits snug without cutting off circulation or pinching skin. A proper fit keeps both attachments stable during thrusting and prevents the harness from riding up or slipping sideways. Comfort matters more than ego when you're planning longer sessions.
How to use it
Attach your chosen dildos to both Vac-U-Lock ports before putting on the harness. Step into the leg straps and pull the waist belt tight enough to prevent shifting during penetration. Position yourself between your partner's legs and guide both attachments to their respective entry points. Velvet should sit flush against your pelvis for maximum control and stability.
Start with shallow thrusts to help your partner adjust to the dual fullness, then increase depth as they relax. Rock your hips in circular motions to stimulate different angles simultaneously. Watch for signs of arousal like increased wetness or muscle relaxation. Push deeper when they start grinding back against you, indicating readiness for harder pounding. After use, machine wash the velvet components and dry thoroughly before storing.

Who it suits
Couples with strap-on experience who want to explore double penetration without involving a third person will find this harness essential. Both partners should have tried anal play before attempting dual entry, since it requires significant preparation, communication, and trust. Strong core muscles in the wearer help control two attachments effectively during thrusting and maintain stability.
Skip this if you're new to strap-on play. Master single penetration first and build comfort with anal preparation before attempting dual entry. Those with hip or back issues might struggle with the additional weight and leverage required. Start slowly, check in often with your partner, and never rush progression.

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
Single-attachment harnesses hold one dildo for vaginal or anal entry, giving you simplicity and easier control. Dual-port harnesses like this one fill both openings at once, creating deeper fullness and more intense sensation across the pelvic region. Single-entry systems suit beginners or those wanting straightforward play; dual-entry systems demand more experience, communication, and physical stamina from the wearer. Explore Adam Eve Sextoys for alternative strap-on systems and harness styles that suit different preferences.
| 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 Couples Intimacy Kits that include complementary strap-on attachments and positioning guides. Kits designed for couples play often bundle different dildo sizes and shapes, letting you customize depth and sensation for both partners. Having multiple attachment options means you can adjust during a session based on how your partner is responding and what feels best in the moment.
