Let's get real for a second. Finding a strap-on setup that feels good for both partners is historically a nightmare. Usually, the wearer is stuck with a plastic-feeling base against their pubic bone while the receiver gets all the action, or worse—you're dealing with a harness that requires an engineering degree to adjust.
If you are searching for a vibrating double penetration strap on, you are likely looking for that "holy grail" of intimacy: a toy that fills you up while you fill your partner up, creating a feedback loop of vibration that connects you both physically and energetically. You want to ditch the strap and find something that stays in place using body mechanics, not nylon webbing.
In this guide, we are looking at why ergonomic, strapless designs are taking over the bedroom and exactly how to use them safely and effectively.
Quick Summary: The "Best Friend" Recommendation
What is the best option? For couples who want simultaneous stimulation without a harness, we recommend the BOMBEX Lesley. It is a triple-motor, medical-grade silicone toy designed to be worn internally by one partner while penetrating the other.
Why? Unlike stiff strapless dildos that slip out the moment you sweat, the Lesley uses a flexible U-shape and bulbous internal anchor to stay put. Plus, it vibrates on both ends (and the middle), so nobody is left out of the fun.

Buying Criteria: What Actually Matters?
What is a vibrating double penetration strap on?
Simply put, it is a dual-ended sex toy designed to penetrate the wearer (vaginally or anally) and the receiver simultaneously, usually enhanced with motors to stimulate both parties at once. While traditional "strap-ons" use a harness, the modern version is often "strapless," relying on pelvic muscles and ergonomic shapes to stay in place.
Before you click "buy" on the first purple thing you see, check these three non-negotiable features. I have tested enough cheap toys to know that skipping these leads to disappointment (and sometimes infection).
- 1. Material Safety (The "Sniff" Test): If it smells like a new shower curtain, run. You need 100% medical-grade silicone. It is non-porous, can be boiled for sterilization, and doesn't leach toxic chemicals. Porous materials (like jelly or rubber) trap bacteria that can cause BV or yeast infections.
- 2. The Anchor Shape: The biggest complaint with strapless toys is that they fall out. Look for a "bulb" or an ergonomic curve on the wearer's end. A straight peg will not stay inside you once things get slippery. You need a shape that hooks slightly behind the pubic bone or uses a bulbous head for retention.
- 3. Motor Placement: A single motor buzzing in the middle often numbs the base without satisfying the tips. High-quality options like the Lesley use independent motors—one for the wearer, one for the receiver, and often a clitoral stimulator in the bridge. This ensures strong vibrations exactly where you need them.
Product Spotlight: Why We Recommend The Lesley
We chose the Lesley: Triple-Motor Detachable Double Dildo for Lesbian Couples because it solves the two biggest pain points of strapless play: stability and "dead zones" (parts of the toy that don't vibrate).
Most strapless strap-ons are rigid. The Lesley is flexible, meaning it moves with your hips rather than levering out of them. It is also a 2-in-1 device; you can detach the vibrator for solo play, making it a versatile investment for your toy drawer.
Comparison: Old School vs. The Lesley
| Feature | Standard Strapless Dildo | BOMBEX Lesley |
|---|---|---|
| Stability | Often rigid; slips out easily during thrusting. | Ergonomic bulb design & U-shape grips the body naturally. |
| Vibration | Single weak motor in the center. | Triple motors (Wearer + Receiver + Clit). |
| Material | Often TPE or TPR (porous/hard to clean). | 100% Body-Safe Silicone (non-porous). |
| Versatility | One piece, one use. | Detachable design for solo or couple play. |
Mastering the Mechanics: Positions & How-To Guide
How do you actually use a strapless double dildo?
The learning curve for strapless toys is real. Unlike a harness that physically ties the toy to you, these toys require a bit of pelvic floor engagement (Kegels) and the right angles. If you just try to thrust like a piston, it might pop out. The trick is "grinding" rather than "pumping."
Here are three positions optimized for the Lesley that maximize stability and pleasure for both partners.
1. The Modified Missionary (The Anchor)
This is the best position for beginners to get used to the sensation of the double dildo.
- The Setup: The receiving partner lies on their back with legs spread or raised. The wearing partner inserts the shorter, bulbous end of the Lesley into themselves.
- The Action: Instead of being on your knees (which tilts your pelvis and can dislodge the toy), the wearer should lie flat on top of the receiver, interlocking legs.
- Why it works: The friction of your bodies pressed together keeps the toy secure. You can grind your clitoris against the bridge of the toy while the long end penetrates your partner. It creates a closed loop of stimulation where you can look each other in the eye.
2. The Spooning Strap (Lazy Sunday)
Perfect for slow, deep intimacy or morning sex.
- The Setup: Both partners lie on their sides facing the same direction (Little Spoon and Big Spoon). The wearer (Big Spoon) slides up behind the partner.
- The Action: The wearer inserts their end first, then uses one hand to guide the penetrating end into the partner. Once inside, the wearer presses their hips firmly against the partner's glutes.
- Why it works: Gravity is neutral here, so the toy is less likely to fall out. The wearer can reach around to stimulate the partner's clitoris or breasts manually while the triple motors provide internal rumble for both. It is less aerobic and more about shared vibration.
3. The Face-to-Face Scissors (The Lotus)
This requires a bit more flexibility but offers the most intense clitoral stimulation.
- The Setup: One partner sits cross-legged or with legs open. The other partner sits on the first partner’s lap, facing them, wrapping their legs around the bottom partner's waist.
- The Action: This position creates a tight seal. With the Lesley situated between you, you rock back and forth in a rhythmic motion.
- Why it works: This is arguably the most stable position for strapless play. Your pubic bones are grinding directly against the vibrating bridge of the toy. The depth of penetration is easily controlled by how close you hug each other.
Pro Tip: The Clench
Regardless of the position, the wearer needs to maintain a light Kegel clench to keep the bulbous end secure. If you find it slipping, add a harness. Most "strapless" toys, including the Lesley, are compatible with O-ring underwear or harnesses if you want to go wild without worrying about slippage.
Safety, Hygiene, and Maintenance
Is silicone safe for everyone?
Yes, provided it is high-quality. We emphasize medical-grade silicone because it is hypoallergenic and non-toxic. Cheaper materials containing phthalates can disrupt hormones and irritate delicate tissues. Always verify the material before insertion.
The Lube Rule: Water-Based Only
This is the most critical rule of toy ownership. Silicone toys and silicone lubricant are enemies. If you use silicone lube on the Lesley, it will cause a chemical reaction that "melts" the surface of the toy, making it gummy and porous. Once that happens, you cannot sanitize it, and you have to throw it away.
Recommendation: Use a high-quality water-based lubricant. It is safe for the silicone, easy to clean up, and won't stain your sheets. According to sexual health resources like Healthline, using plenty of lubricant reduces friction and prevents micro-tears in the vaginal wall, which is essential for double penetration play where friction is doubled.
Cleaning Routine
You are dealing with fluids from two people, so hygiene is paramount to prevent passing bacteria back and forth (even if you are fluid-bonded partners, clean toys last longer).
- Immediate Rinse: After use, rinse the toy with warm water to remove excess fluids.
- Soap Up: Use a mild, fragrance-free antibacterial soap or a specialized toy cleaner. Scrub every crevice, especially around the charging port (ensure the port is sealed or waterproof rated before submersion).
- Dry Thoroughly: Silicone can attract lint. Air dry it on a clean towel or pat dry with a lint-free cloth.
- Storage: Store your Lesley in a fabric pouch or a clean drawer, away from other toys. Soft toys made of different materials can react with each other if they touch for long periods (a process called "melting").
Frequently Asked Questions (FAQ)
Can I use the Lesley double dildo for solo play?
Absolutely. One of the best features of the Lesley is its detachable design. You can separate the vibrating element to use as a handheld vibe or use one end of the dildo for standard penetration. It is a versatile tool that adapts to whether you are with a partner or enjoying some "me time."
Will a strapless strap-on fall out during sex?
It can if the fit isn't right or if you use too much vigorous thrusting without pelvic engagement. Strapless toys rely on the "wearer" clenching their PC muscles (Kegels) to hold the internal bulb in place. For wilder, faster sessions, we recommend wearing a tight pair of panties or an O-ring harness over the toy to keep it secure without sacrificing the double stimulation.
Is the Lesley toy waterproof?
Yes, the Lesley is designed with high-grade silicone and sealed charging ports, making it waterproof. This means you can take it into the shower or bath for aquatic play. Just be sure to dry it thoroughly before charging it again.
How loud are the motors?
The Lesley features whisper-quiet technology. While no powerful motor is completely silent, the silicone body dampens the sound significantly. Under the covers or with a little background music, it is discreet enough that housemates likely won't hear a thing.
Does the size matter for the wearer?
Yes. Since the wearer must accommodate the internal anchor, it helps to be comfortable with vaginal insertion. The Lesley is designed with an ergonomic, average-sized bulb that fits most users comfortably, but if you have conditions like vaginismus, you may want to practice with smaller trainers first.
Final Thoughts
Switching to a vibrating double penetration strap on like the BOMBEX Lesley changes the dynamic of couple's play. It removes the barrier of "strapping in" and replaces it with a shared, intimate experience where both partners are stimulated simultaneously. It requires a little practice to master the hold, but the payoff—hands-free, face-to-face connection—is worth every second.
