The Menage A Trois is a complete double-penetration harness and dildo set engineered for even, simultaneous penetration. The thong-style harness is built from nylon webbing with nickel-free metal hardware, plastic hardware, and brass hardware, delivering a secure, skin-friendly fit. A built-in cock ring lets you attach a second toy for full double penetration, while three interchangeable O-rings — a 1.5" rubber ring, a 1.75" metal ring, and a 2" rubber ring — allow the harness to accommodate most flared-base dildos. Adjustable waist and thigh straps fit hips up to 60" / 152.4 cm, and once the harness is positioned, play is completely hands-free. A Sportsheets Flare Dildo (5.75" / 14.61 cm, silicone) is included so you can get started right away.

Intensity & Experience Level

Level: Beginner — Sensation: Restrictive / penetrative

The simple thong-style design and wide strap adjustment range make this an accessible entry point for first-time strap-on wearers, while the interchangeable O-ring system offers room to grow into different dildo sizes. The 5.75" starter dildo keeps depth manageable for newcomers, though the double-penetration capability via the built-in cock ring can escalate intensity for more experienced users.

Who is this product for?

• Couples exploring double penetration or pegging: a ready-to-go set with a secure harness and starter dildo included.
• People managing erectile dysfunction or premature ejaculation: provides a reliable, pressure-free way to continue penetrative intimacy.
• Strap-on beginners: the thong fit, wide adjustability, and simple O-ring mechanism lower the learning curve.
• Gender-affirming and trans users: supports penetrative roles and intimate connection in an affirming, body-inclusive way.
• Users with limited hand mobility: once in place, the harness holds the dildo without requiring manual gripping throughout play.

How to use the Menage A Trois?

1. Select the O-ring that best fits your dildo — start with the included 1.75" metal ring for the Sportsheets Flare Dildo if you are unsure.
2. Slide the dildo through the chosen O-ring until the flared base sits flush and secure against the ring.
3. Step into the thong-style harness and pull it up like underwear, then tighten the waist and thigh straps to a snug, comfortable fit.
4. Comfort checkpoint: verify the harness feels secure but not painfully tight, and that the dildo is centred and stable before proceeding.
5. To add double penetration, attach a compatible toy to the built-in cock ring and position it against the body.
6. Apply water-based lubricant generously to the dildo (and any second toy) before insertion for smoother, more comfortable penetration.
7. Begin at a pace comfortable for the receiver; recommended positions include doggy style for control and angle, cowgirl so the receiver manages depth and rhythm, or missionary for frontal intimacy and full-body contact.
8. Stop and release: to end play, loosen the harness straps, remove the second toy from the cock ring first if used, then slide the harness off. Never force or rush removal if straps feel stuck — loosen all adjusters fully before stepping out.

Techniques & ways to play

• Solo strap-on practice: wear the harness alone to get comfortable with fit and movement before partnered play.
• Pegging: one partner wears the harness and penetrates the other anally, using ample lubricant and taking time to warm up.
• Double penetration: attach a second vibrating or non-vibrating toy to the built-in cock ring for simultaneous vaginal and anal penetration.
• Dildo swapping: use the interchangeable O-rings to try different compatible flared-base dildos and vary size or texture.
• Dom/sub dynamic: the wearing partner holds physical control of depth and thrust; agree on a safeword and negotiate pace, depth, and use of the second toy before escalating intensity.

Pairs well with / Complete the scene

• Water-based lubricant: essential for safe use with the silicone dildo — required, not optional.
• Additional flared-base dildos: expand possibilities using the included O-rings with other compatible toys.
• Remote-controlled vibrating dildo: thread through the cock ring to add vibration to the double-penetration experience.
• OhNut wearable buffer: helps partners manage penetration depth and reduce discomfort, especially useful for newcomers.
• Silicone toy cleaner: keeps the included dildo hygienic and surface-safe between uses.
• Explore the Strap-On & Harness and Couples Play collections for complementary products.

How to clean and care

• Silicone dildo cleaning: wash with warm water and mild soap or a dedicated toy cleaner before and after every use.
• Harness cleaning: wipe down with a damp cloth after use; hand wash with mild soap when a deeper clean is needed.
• Drying: allow all components to air dry completely before storing to prevent mildew and material degradation.
• Lubricant compatibility: use water-based lubricant only with the silicone dildo — silicone-based lubricants can degrade silicone surfaces.
• Storage: store in a cool, dry place away from direct sunlight. Keep the silicone dildo separated from other silicone toys to prevent surface reactivity.

Additional information

• Versatility: the interchangeable O-ring system lets you swap in other flared-base dildos to vary size, shape, or material over time.
• Hands-free design: once secured, the harness holds the dildo in position without requiring manual grip, reducing strain during extended play.
• Accessibility: reduces the need for continuous arm or hand involvement, helpful for users with limited upper-body mobility or grip strength.
• Intimacy support: provides a means to maintain penetrative intimacy when physical sensation or performance may be limited, without pressure or performance expectation.

Special considerations / warnings

• Mobility requirements: stepping into a thong-style harness and adjusting hip and thigh straps requires a degree of balance and lower-body flexibility; seated fitting is an option if standing is difficult.
• Dexterity: threading the dildo through the O-ring and tightening the straps requires moderate hand and finger dexterity; a partner can assist with this step.
• Reach: adjusting straps at the hips and lower back may be challenging for users with limited reach; plan for a partner's assistance if needed.
• Lubrication is essential: always apply water-based lubricant before any penetration to prevent discomfort, micro-tearing, or pain.
• Painful penetration: if penetration causes pain, stop immediately. Consider a smaller dildo, additional lubricant, or a depth-limiting buffer such as the OhNut.
• Not a medical device: this product is a pleasure accessory and is not intended to diagnose, treat, or manage any medical condition.
• Hardware sensitivity: hardware is nickel-free, but if you have known metal allergies beyond nickel, check material details before use.
• 18+ only. For consensual adult use.
