Feelztoys aren't messing about with the Cunter. Made of heavy duty, flexible silicone and with a powerful in-built vibrator, this product is pretty much the daddy of all prostate massagers.

Cunter has a ribbed, knobbly shaft and thick, heavy bulge at the end, designed for stimulating a man's prostate. At about five inches long, it's not a devastatingly enormous product and most people should be able to insert it comfortably, as long as they use enough lube. Just make sure it's not silicone-based lube, though, as that will damage the Cunter.

At the base of the knobbly shaft is a subtle, but effective flange to prevent the vibrator disappearing into a hungry orifice! The flange is well designed, though, with ergonomic curves that mean it fits snugly and comfortably in the crack of one's ass.

At the base of the Cunter is the on/off switch. This is a single button - sounds simple, right? Actually, that button cycles through a variety of different 'programs' of vibration, from simple and gentle to throbbing, powerful and unpredictable. It makes the whole device perfect for those who like to mix up their stimulation.

The only criticism is that the button on the base is the ONLY control, meaning it's not exactly intuitive how to switch the vibrator off! In actual fact, you just have to press and hold the button.

The whole product is made from silicone, which means it's easy to wash in hot water, with soap and disinfectant. It's also totally safe to boil, although the inbuilt battery compartment means you can't just sling it in the dishwasher. The fact that it's made from such safe material, however, means it's perfect for sharing or those who want to use it (once properly washed) in another orifice. The design and 'bulge' at the top makes it very suitable for stimulating a woman's g-spot, for instance.

The vibrator is powered by two AAA batteries, which mean the batteries are easy to replace and the vibrations are fairly strong. One recommendation: Remove the AAA batteries when you're not using it, as it's surprisingly easy to accidentally switch it on!

My wife used the Cunter on me while she was giving me a long, lavish blowjob. I loved it - the vibrator is small and slim enough to make it easy for my wife to lather it up with water-based lube and slip it inside. It nestled in my ass quite snugly, although might have popped out if I'd been standing up or tried to walk about.

The vibrations are awesome. My wife gave the full range of cycles a whirl and they varied from ultra-subtle (pretty much too subtle for me to notice) to some really arousing vibe programs that mixed up the sensations into pulses of varying length and power. That, combined with my wife's tongue bath of my erection, made for some incredibly intense experiences! I came very quickly and very powerfully, with my wife gulping down my cum at the same time she coaxed more out of me by thrusting the Cunter in and out of my ass.

Afterward, it was incredibly simple to wash the Cunter under the hot tap, with plenty of soap. I did notice, however, a ton of lint stuck to it when I dried it with the towel!

Although this clearly a product made for men, specifically to tease and tantalize their 'p' spot, we've now found ours gets more use in my wife's willing pussy. The 'ball' at the curved end is just perfect for massaging her g-spot when slid inside her, and the dense silicone toy carries the adjustable vibrations perfectly.

The fact that the vibrations are so strong, and you can 'mix things up' with an assortment of different vibe patterns, means that she feels very satisfying internal stimulation when the Cunter's buried in her cunt.

Formerly the rabbit had been her favorite toy, but this is fast becoming its replacement. The main criticism is that the Cunter's not great at clitoral stimulation; although the 'flange' that makes it safe for anal play does carry some of the vibrations to her clit, and jiggles the crack of her ass very nicely.

However if I'm fucking her with this toy, I can usually make up for the clitoral shortfall with my fingers or tongue.

Even better, the whole product is perfectly safe to use in her pussy, or my ass, as long as we sterilize it afterward. Although silicone doesn't feel as nice as cyberskin, that's reassuring and convenient considering this is now a 'two hole' toy and no longer just an anal adventurer.
