Lock-In Dual-Ended Vibrating Strap-On Set by Together

Lock-In Dual-Ended Vibrating Strap-On Set by Together is a wearable vibrator designed for couples, with one end inside the wearer and one end for their partner. It combines adjustable vibration with a secure harness, so both people can focus on sensation rather than fit or slippage.

What you're getting

Lock-In Dual-Ended Vibrating Strap-On Set by Together includes a two-part silicone vibrator with bulbous heads on each end, a stretchy polyester harness with iron hardware, and a USB charging cable. The harness is contoured to cup the wearer's genitals, so the vibration reaches both partners during partnered intercourse. Most vibrators work on a single body; this one is engineered so penetration and external stimulation happen at once.

The silicone is smooth and non-porous, which makes cleaning straightforward. Its waterproof construction means you can use it in the shower or bath without worry. The magnetic USB charging means no exposed ports to trap moisture or collect debris—you simply dock it against the magnet to top up the battery.

The features that matter

• Dual insertion and external contact: One end enters the wearer while the other end rests against their partner's body, so both receive vibration during intercourse.
• 10 vibration modes: Choose from a range of steady and patterned vibrations, each adjustable at the press of a button during use.
• Curved bulbous heads: The enlarged ends are shaped to target sensitive internal tissue and provide broad stimulation rather than pinpoint contact.
• Secure harness design: The stretchy waistband and contoured base keep the vibrator anchored so it does not shift during movement or thrusting.
• Fully waterproof: Submerge it completely in water for shower use, and the waterproof seals protect the motor and battery underneath.

How to use a vibrating vibrator

Before first use, charge the vibrator fully using the magnetic USB cable—this typically takes two to three hours. Wash the silicone ends and harness with warm soapy water and dry completely. Adjust the waistband by stretching it or fastening the elastic loops to sit comfortably at your hip. Apply a water-based lubricant to both silicone ends and the wearer's opening, then step into the harness and adjust the fit so the wearer's end is aligned with their opening and the partner-facing end rests at the right angle for contact with their body.

Once positioned, turn on the vibrator using the button on the harness and cycle through the vibration modes to find the intensity and rhythm you both prefer. During use, you can adjust the mode mid-session without removing the harness. Unlike finger vibrators, which require a hand to hold and guide, this design leaves both people free to move, touch, and maintain eye contact. After use, wash the silicone with soap and water, wipe the harness clean, and allow both to air dry before storing in a cool, dry place away from direct sunlight.

Who gets on with it

Care and storage

Rinse the silicone ends under warm running water and wash with a mild soap immediately after use to remove lubricant and body fluid. Wipe the harness clean with a damp cloth and pat dry. Store both the vibrator and harness in a cool, dry place away from direct sunlight, which can degrade silicone over time. Keep the magnetic charging cable in a safe spot so you can top up the battery before each session. Do not expose the vibrator to extreme heat or leave it in direct sunlight for extended periods.

More on the subject

Couples vibrators work differently depending on whether they prioritise external stimulation, internal reach, or shared contact during penetration. This design focuses on simultaneous pleasure for both partners during face-to-face intercourse.

What to expect

The Lock-In Dual-Ended Vibrating Strap-On Set by Together feels substantial when you first hold it because of its silicone weight and the polyester harness. Most first-time users spend ten to fifteen minutes adjusting the waistband before play to avoid discomfort during longer sessions. The vibration is buzzy rather than deep, so you will feel it most at the outer surfaces of the silicone bulbs rather than as a strong rumble deep inside.

The real adjustment is positional: getting the angle right so that both the internal and external ends make contact at the same time takes a few tries. Many couples find that slight shifts in hip position or leg stance during use change where sensation lands. The harness stays put during gentle rocking but can creep slightly with vigorous thrusting, so checking the fit between position changes helps.

Cleaning is straightforward because silicone does not absorb fluid and washes easily under warm water. The magnetic charging dock is reliable and holds a charge for several hours of mixed-mode use; most people charge it weekly if they play once or twice a week. The material itself is durable and does not pit or stain with normal care.

People who struggle with conventional harnesses often get on well with this design because the waistband is elastic rather than rigid. Those who prefer deep, rumbly vibration over a buzzy sensation sometimes find the intensity lower than they expected. The toy is not suitable for solo use by either partner alone—it is built specifically for two people to wear together.
