Once you try one of these plugs you’ll understand why we named them the way we did. WMCBP’s are great for long term wear and come in Small through XXL, so there’s a plug to fill any hole. Made from body safe silicone with a weighted steel core.

Silicone World's Most Comfortable Butt Plug

This is the silicone adaptation of the original World's Most Comfortable Butt Plug. The WMCBP line also includes a Vibrating WMCBP, and the E-WMCBP 2.0 which can be hooked up to your favorite tens unit!

Because they're so comfortable, the entire WMCBP line can be worn for many hours. For the Silicone WMCBP, we’ve changed out the aluminum and rubber for silicone. We’ve also added in an internal steel weight, so you get that same heft you’ve come to know and love from our original design. If you like the feel of a butt plug, try one of these - you may just never want to remove it, and you'll LOVE the weight of this toy pressing on your prostate.

The shape of this black Silicone World's Most Comfortable Butt Plug makes insertion simple and once inside gives you a nice, full feeling. The narrow stem lets your hole relax so you can keep this plug lodged inside your hole comfortably. The rectangular base keeps the plug from going too deep and acts as a nice handle.

Once you try this Silicone WMCBP out for yourself, you’ll see why we named it the way we did!

Care & Cleaning

We recommend Mr. S Bodyglide Silicone Lube or any water-based lube for use with these plugs. Wash with warm water and dish soap or use a toy cleaner. Let air dry and store separately from other toys.

We offer a couple pointers to ensure the safe usage and longevity of this very unique product:

When you are ready to remove the plug, relax and simply push the toy out. Do not pull on the base or stem as means for removal.

Any item being inserted in your body should be inspected for cracks, breaks, or rough edges before inserting the item. If you find any cracks or weak spots in Silicone World's Most Comfortable Butt Plug, do not use the product and give us a call.
