The Body Extensions Be Naughty Vibrating 4-Piece Strap-On Set by Doc Johnson is built for couples who want penetration play and shared stimulation, without making anyone’s anatomy the limiting factor. It’s a hollow strap-on system with a premium silicone harness and built-in vibrator, designed to feel good for the wearer and the receiver at the same time.

At the center is a wireless, rechargeable harness with a 10-function vibrator positioned to stimulate the wearer during thrusting. Control it with the included remote or the on-harness buttons, then switch modes mid-session without breaking the moment. The elastic waistband stretches to fit 28" to 48" (71 to 122 cm), and nickel-free hardware keeps it body-friendly.

You also get three hollow silicone attachments, each made from hypoallergenic, nonporous, odorless, phthalate-free silicone. They’re designed to hold their shape while staying soft and smooth, making penetration feel more natural and consistent. Choose the profile that matches the vibe you want that night: bulbed for fullness, slim for easier entry and longer play, or large when you want more presence.

Hollow dildos are wide enough to accommodate an average-sized flaccid penis inside. This means that the outside of hollow dildos are larger than average dildos. They are rigid because they must maintain their shape and accommodate a penis inside, but this one has some flex.

If you have Erectile Dysfunction (ED) and have never used a hollow dildo before, feel free to explore our helpful guide, Sex Toys For Erectile Dysfunction, to better understand how they work and options.

Vibration Intensity 3 | 5
Intensity 3: There are two types of vibration often described: deep and rumbly or surface and smooth. This vibrator features a deep and rumbly vibration and is for those who enjoy moderate stimulation.

Noise Level 2 | 5
Level 2: This is a low-volume vibrator that is similar to the sound of someone whispering. It is not likely this would be able to be heard through a door. It is easily disguised by using under the covers, with soft music or a white noise machine.
