Hey folks, boxersoverbriefs doesn’t have a vagina with which to try out this product, so he’s asked me, his lady friend and partner, to put in my two cents. And with that, on to the review:

The Smart Balls Teneo duo is a remarkably well-made toy. First of all, Fun Factory packages everything up nicely and includes fairly extensive instructions (and diagrams!), so getting started is a cinch. The silicone outer layer makes it easy to clean, and doesn’t have the icky chemical smell present in some other products. Both balls have small ridges, which I suppose are meant to add pleasure, but are really more of an aesthetic thing. The second ball has a finger-sized groove on its end, giving the user better leverage for insertion, which is especially useful when sampling the trial-sized packet of lube that comes included with the toy.

It should be noted that silicone-based lubes are a no-no here; they will degrade the material. Water and oil-based lubes on the other hand are a-ok. The extraction cord is “elastomed” coated in silicone, making it stretchy and ensuring that you can’t “accidentally” pull the balls out at an inopportune time, but strong enough to withstand a forcible yank.

While the Smart Balls are advertised as vaginal muscle strengtheners, my experience is that they could easily be marketed as more of a straight-up sex toy. When I first got the product, I put it in for an afternoon of running errands. Within each hollow outer ball is a weighted inner ball, which rattled around whenever I moved, causing slight vibrations within my vagina. Hint: the greater the movement, the greater the rattling.

My partner jokingly got me to skip around a bit and it felt great. Even just sitting at the right angle caused pleasurable feelings, and driving over speed bumps was dangerously distracting. I can only imagine what bouncing around on a trampoline would do! And not only was there constant physical stimulation, but the psychological thrill of doing something secretly naughty, in a public setting, was quite delightful as well.

In the bedroom, the Smart Balls are a diverse product as well. When pulled upon gently, the springy removal band pulls the outer ball into contact with the outermost ring of vaginal muscles, which gives a wonderful sense of tension. My partner masturbated me like that, pulling the outermost ball slowly out, then pushing it back in, and I had one of the quickest orgasms of my life. (Granted, I had been wearing the balls all day and was horny as hell to begin with). We also tried anal intercourse while I had the balls inserted,and the added feeling of fullness and pressure was pretty great.

I can’t speak yet to the muscle strengthening properties of the balls, as I’ve only used them a couple of times. It will be something to remark upon in a follow-up review. Overall, I highly recommend the Smart Balls Teneo duo. They’re easy and enjoyable to use, versatile, and they (theoretically) keep your cooter tight to boot!
