After playing with the Rump Shakers Small for a while, I wanted something a bit larger to use. Since I enjoyed the Small, I thought I’d give the Medium a try. The Medium Rump Shaker from Doc Johnson is low priced, and comes in four colors. I chose black to make it accessorize better with the type of play I had in mind. The plug is about 5 1/2" long, with an insertable length of 4 1/2". It tapers from about 1” at the tip to a maximum of about 1 3/4" in diameter.

The plug then thins down at the neck. The base is flared, and the cord to the controller comes out of the bottom of the base. The controller is also black, and takes 2AA batteries. The vibrations are controlled with a dial and can go from gentle to quite powerful. It's noisy when you hold it in your hand, but when it's inserted; the noise level is not too loud at all.

The Shaker is made of smooth rubber, and it smells coming right out of the box. Rubber is a porous, low wear material and typically has a funky smell. I washed and aired this toy out a few times, and the smell did mostly dissipate. Since rubber is porous, it’s a good choice to use a condom during each use. Both silicone and water-based lubes are safe to use with rubber.

The Medium plug has some flexibility to it, and is not hard or rigid like glass or acrylic plugs. It can be separated from the controller pack, so you can use another style that has pulses, etc. if you desire.

Because this plug is so wide I warmed up with a smaller one first, before my husband tried to put this in. He lubed it liberally, turned it on, and started pushing it in. At first I couldn’t take the whole thing, but he kept working it in a bit at a time, and I kept my clit busy, until it finally went all the way in. This boy is big! My ass could really feel it, and with the vibrations turned up, it didn’t take me long to climax. We did find that this made it easier for us to have anal sex – it opened me wide enough so he was able to penetrate my ass more easily.

Overall, I would recommend the Rump Shaker Medium, especially if you like larger toys. It packs a good buzz for the money, and it can help widen you for anal sex.

I love the size of this toy, and that it vibrates. While this isn't something to be worn out for long periods of time, it does its job well during sex. I also love that the remote can be changed since the toy jacks into it. The original remote just dials up the vibrations, but use a pulsing remote, and wow - you can really get some good sensations going.

So far, this plug has held up well, with no tearing of material, and the scent has pretty well dissipated. I would really like to have a plug this size and shape in silicone, but until then this will stay in my anal arsenal.
