Robo Rimmer Butt Plug by Doc Johnson

The Robo Rimmer Butt Plug by Doc Johnson is a dual-engine anal plug that combines internal vibrations with rotating external ridges for simultaneous deep and sphincter stimulation. A wireless remote controls both functions independently, making it ideal for hands-free solo sessions or partner-directed play.

What it is and how it's made

The Robo Rimmer Butt Plug by Doc Johnson pairs two separate motors: one inside the plug head for vibration, and one driving mechanical ridges around the opening for external rimming sensation. The silicone body tapers smoothly for easier insertion and sits cushioned against your skin once in place. Unlike most butt plugs, which deliver only internal stimulation after insertion, this plug keeps working your most sensitive nerve endings through continuous rotating action.

The dual-engine design sets it apart. While the vibrations pulse deep inside, the rotating ridges create a consistent mechanical massage around your entrance — mimicking external oral stimulation that does not tire. The wireless remote gives you independent control of both functions, meaning you can dial up vibration while dialling back the ridging, or sync them for compound sensation.

Features worth knowing

• Eight vibration patterns: Multiple settings inside the plug head let you find the rhythm that suits your prostate and internal sensitivity.
• Five rimming patterns: Mechanical rotating ridges offer variety in speed and intensity around your sphincter without fatigue.
• Independent remote control: Each engine responds to separate commands, so you customise internal and external stimulation separately or together.
• Rechargeable and cordless: USB charging means no battery changes mid-session; wireless operation frees your hands entirely.
• Tapered silicone body: Soft, body-safe material slides in smoothly and remains comfortable during extended wear or active sessions.

Working up to a butt plug comfortably

Start with plenty of lubricant — more than you think you need — applied to both the plug and your entrance. Begin with the lowest vibration setting and no rotation to let your body adjust to the sensation and depth. The tapered design slides in gradually, so breathe slowly and relax your sphincter as it widens. Once fully inserted, pause for a moment before activating any movement; this gives your muscles time to settle.

Once you are ready for stimulation, activate vibration first at a low setting. Let your body get used to the internal pulsing before adding the rotating ridges. The mechanical rimming sensation is intense, so introducing it slowly prevents overwhelming yourself. Many people find starting with rotation off and vibration on, then gradually adding ridging over several minutes, creates a more sustainable session. Try Bendable Silicone P Spot Beads beforehand to warm up your prostate; this often makes dual-engine play more comfortable and responsive.

Care and storage

Wash the silicone body with warm water and mild soap after each session, paying special attention to the ridged areas where lubricant can collect. Dry thoroughly with a soft cloth. Charge the plug monthly even during storage to keep the battery healthy. Store in a cool, dry place away from direct sunlight. Keep the remote separate in a drawer to protect the battery contacts.

What to expect

First-time users often underestimate how intense the rotating ridges feel compared to vibration alone. The mechanical action is relentless once activated — it does not pause or tire — so many people find that starting with rotation off and adding it gradually creates a more controlled introduction. The tapered design slides in smoothly with enough lubricant, but the flared base takes a moment to settle; rushing this step often leads to discomfort.

The dual-engine setup means you are managing two separate sensations at once. Some users sync the patterns for compound intensity; others prefer to keep one feature subtle while the other leads. Experimenting across multiple sessions helps you find your sweet spot. The wireless remote works reliably at close range, though moving it too far away (more than a couple of metres) can cause signal drop.

Cleanup is straightforward because silicone is non-porous, but the ridged exterior does trap lubricant. Rinsing thoroughly and drying completely prevents residue buildup. Battery life after a full charge typically supports several sessions; charging monthly during storage keeps the plug ready when you need it.

Comfort improves noticeably after your first two or three sessions as your body learns to relax into the shape and anticipate the sensations. Many people report that the rotating ridges become more pleasurable once the initial novelty wears off and you stop bracing against them.
