Let’s get real for a second. We have all been there—fumbling with buckles, adjusting nylon straps that dig into your hips, and trying to keep the mood alive while you figure out which loop goes where. If you are looking for the best double penetration strap on, you are probably chasing that holy grail of mutual connection: feeling your partner inside you while you are inside them. But traditional harnesses can sometimes feel like literal baggage.
The biggest pain point I hear from our community? "It just doesn't feel natural." There is a layer of fabric between you, the dildo flops around, or the wearer feels left out of the sensation. That is why the market is shifting. We are seeing a massive move toward ergonomic, strapless designs that stay in place using your own anatomy, not a buckle.
Quick Summary: The "TL;DR"
What is a Double Penetration Strap On?
Traditionally, this refers to a harness kit with a double-ended dildo or a setup allowing one partner to wear a dildo while being penetrated. However, modern "strapless" double dildos function as an all-in-one wearable unit, allowing both partners to be penetrated simultaneously without external straps.
Top Pick for 2025:
We recommend the Lesley: Triple-Motor Detachable Double Dildo for Lesbian Couples. It solves the "slippage" issue with a U-shaped ergonomic design and adds triple motors so the wearer actually enjoys the ride too.
What to Look For Before You Buy
Before you drop money on a new toy, you need to understand the mechanics. A double penetration toy has a much harder job than a solo vibe. It has to fit two bodies, two anatomies, and two sets of movements simultaneously.
1. Material Safety (The Non-Negotiable)
What is it? The substance the toy is made from.
Always check for "Medical-Grade Silicone." If a listing says "Jelly," "PVC," or "TPR," close the tab. Research highlights that some plasticizers used in sex toys are associated with toxic reproductive and developmental effects. We will get into the science of safety later, but knowing your materials is step one.
2. The "Wearer" Experience
What is it? How the active partner keeps the toy in place.
In a traditional strap-on, stability comes from the harness tightness. In a strapless double dildo, stability comes from the bulb or handle that sits inside the wearer. Look for a bulbous, ergonomic shape (often U-shaped) that grips the pelvic floor muscles. If the internal anchor is too straight or thin, it will pop out the moment things get fun.
3. Motor Placement
What is it? Where the vibration comes from.
Many old-school options only vibrate at the tip (for the receiver). This is tragic for the wearer! The best modern options, like the Lesley, use a multi-motor system. You want a motor in the internal arm (for the wearer), a motor in the shaft (for the receiver), and ideally a clitoral stimulator at the connection point.
Product Spotlight: Why We Recommend The Lesley
When we tested various setups, the frustration with harnesses was universal. They break the flow. The Lesley: Triple-Motor Detachable Double Dildo for Lesbian Couples stood out because it fixes the "disconnection" problem. It’s designed specifically for lesbian couples who want skin-to-skin contact without a barrier.
Here is a breakdown of why this strapless design beats the traditional harness setup:
| Feature | Traditional Strap-On Kit | BOMBEX Lesley Strapless |
|---|---|---|
| Setup Time | High (Adjusting buckles, fitting harness) | Instant (Insert and play) |
| Sensation for Wearer | Often none (unless using a specific insert) | Intense (Internal vibration + G-spot stimulation) |
| Intimacy | Barrier of fabric between bodies | Full skin-to-skin contact |
| Versatility | Usually couple-play only | 2-in-1 Detachable (Can be used solo) |
Mastering the Art: Positions for Strapless Play
If you are switching from a harness to a strapless double dildo like the Lesley, there is a learning curve. Since you don't have nylon straps doing the heavy lifting, you need to use your body mechanics to keep things secure. The secret is usually in the "clench" and the angle of the hips.
Here are four positions that maximize stability and pleasure for both partners.
1. The Scissor Lock (Face-to-Face)
This is the ultimate intimacy position and works beautifully with the U-shape of the Lesley. It allows for deep kissing and eye contact while maintaining a tight seal.
- How to do it: Both partners lie on their sides facing each other. The wearer (Partner A) inserts the shorter end. Partner B slides closer, interlocking legs.
- The Trick: Intertwine your legs completely—Partner A’s top leg should go over Partner B’s hip. This pressure helps keep the toy pressed firmly against both vulvas, increasing the vibrations from the external motors against the clitoris.
- Why it works: The side-lying gravity is neutral. The toy isn't fighting to fall out; it’s resting naturally between you.
2. The Anchor Missionary
Classic for a reason, but with a strapless toy, the mechanics shift slightly to ensure the wearer stays stimulated.
- How to do it: Partner B (receiver) lies on their back. Partner A (wearer) climbs on top. Unlike a standard strap-on where you can kneel upright, Partner A should stay lower, keeping their pelvis pressed close to Partner B.
- The Trick: Partner A needs to engage their pelvic floor muscles (Kegels) to grip the internal bulb. Partner B can help by wrapping their legs around Partner A’s lower back, creating a "vice" that keeps the toy secure during thrusting.
- Why it works: This position gives the wearer the most control over depth and pace.
3. The Lazy Spoon
Perfect for long, slow sessions where comfort is king. This is less about hard thrusting and more about grinding and shared vibration.
- How to do it: Both partners lie on their sides, facing the same direction (Partner A behind Partner B). Partner A inserts the wearer end and slides up snugly behind Partner B to insert the receiver end.
- The Trick: Partner B should arch their back slightly to meet the toy. Partner A can use one hand to hold their own hip or thigh to generate leverage for shallow, rhythmic thrusts.
- Why it works: The "Lesley" fits ergonomically in this curve. It’s a very stable position because Partner B’s buttocks act as a buffer that keeps the toy pushed back into Partner A.
4. The Seated Rider
This position offers deep penetration for the receiver and intense G-spot stimulation for the wearer.
- How to do it: Partner A sits on a sturdy chair or the edge of the bed, feet planted firmly on the floor. Partner B straddles Partner A, facing them.
- The Trick: Gravity is your friend here. Partner B controls the depth by raising and lowering their hips. Partner A simply needs to tilt their pelvis upward. The downward weight of Partner B forces the internal end of the toy deeper into Partner A, creating a "fullness" sensation that many wearers love.
- Why it works: It is hands-free and face-to-face. Plus, the triple motors of the Lesley will be directly stimulated by the pressure of the bodies pressing together.
Critical Safety & Hygiene: Don't Skip This!
When you are introducing a toy into two bodies simultaneously, hygiene isn't just a suggestion—it’s a requirement. Double penetration means double the bacterial environment, so you need to be smart about materials and cleaning.
The Science of Silicone
You will notice we stress body-safe silicone constantly. Here is why: Cheap toys are often made of porous materials like Jelly or TPR (Thermoplastic Rubber). Under a microscope, these materials look like a sponge. They have tiny holes that trap bacteria, yeast, and microscopic debris. No matter how much you scrub, you cannot fully sterilize them, which can lead to vaginal and anal infections.
According to Planned Parenthood’s sex toy safety guidelines, non-porous materials like 100% silicone are the gold standard because they don't have these hiding spots for bacteria. The Lesley is made from medical-grade silicone, which is non-porous, boilable, and hypoallergenic. When you are swapping fluids between partners, this barrier against bacteria is vital to prevent BV (Bacterial Vaginosis) or yeast infections.
Lube Logistics: Water vs. Silicone
This is a rule you must memorize: Never use silicone lubricant with silicone toys.
- The Chemistry: Silicone attracts silicone. If you apply a silicone-based lube to a silicone dildo, a chemical reaction occurs that breaks down the surface of the toy. It can cause the toy to melt, bubble, or become sticky and porous (ruining that safety feature we just discussed).
- The Solution: Always stick to high-quality water-based lubricants. They are safe for all materials, easy to clean up, and won't damage your investment. Since the Lesley is waterproof, you can also use it in the shower, where water-based lube is even more helpful to counteract the washing away of natural lubrication.
The Cleaning Routine
Because the Lesley is detachable (a huge perk!), cleaning is easier than with a one-piece molded toy.
- Immediate Rinse: After use, rinse with warm water to remove fluids.
- Soap: Use a mild, unfragranced soap or a dedicated sex toy cleaner. Antibacterial soap is okay, but make sure to rinse it thoroughly so it doesn't irritate your skin later.
- Dry: Air dry or pat with a lint-free cloth. Lint on a silicone toy is annoying and not great for insertion!
- Storage: Store it in a pouch or box away from other toys. Silicone toys should not touch other materials during long-term storage as they can sometimes react.
Frequently Asked Questions
How do I keep a strapless double dildo from falling out?
This is the most common concern! The key is Pelvic Floor engagement. The wearer holds the internal bulb in place using their kegel muscles. Additionally, choosing a toy with a bulbous, ergonomic shape (like the Lesley) helps anchor it naturally. Position matters too—positions where the receiver’s body presses back against the wearer (like spooning or scissoring) help maintain the seal better than positions where you are far apart.
Can we use this if we have a significant height difference?
Yes, absolutely. In fact, strapless toys often work better for height differences than harness-based ones because you aren't limited by the angle of the plastic O-ring on a harness. The "Seated Rider" position is excellent for couples with height differences, as the seated partner provides a stable base regardless of leg length.
Does the Lesley vibrate for both partners?
Yes. The Lesley features a triple-motor design. This ensures that vibrations travel through the entire silicone body, stimulating the wearer internally, the receiver internally, and the clitorises of both partners where the toy connects.
Is a double dildo safe for beginners?
It can be, provided you take it slow. "Double penetration" implies filling two canals at once, which requires plenty of lubrication and communication. We recommend beginners start with the solo mode (since the Lesley is detachable) to get used to the size and sensation before attempting simultaneous couple play.
Can I boil the Lesley to sterilize it?
While the silicone sleeve is medical-grade and technically boil-safe, the Lesley contains electronic motors and batteries. You cannot boil the electronic components! You should clean it with warm soapy water or a dedicated toy cleaner. Do not submerge the charging port area for extended periods in boiling water.
Ready to Ditch the Harness?
Double penetration play shouldn't feel like a logistical puzzle. It should be about closeness, rhythm, and shared pleasure. By moving away from nylon straps and opting for an ergonomic solution like the Lesley, you are prioritizing intimacy over mechanics.
Whether you are trying the "Scissor Lock" for a romantic night in or experimenting with the detachable solo modes, having the right tool makes all the difference. Stay safe, use plenty of water-based lube, and enjoy the connection.
