We all know about the Japanese creativity and this is yet another proof. A while ago, they invented one of the most famous sex toys. Geisha balls, also known as Ben Wa balls or Burmese balls, these little items responsible for the improvement of the sex life of many users, are two small balls made of plastic or thin metal and contain a small weight that rolls around - most of the times one of them contains a third smaller one that is filled with quicksilver in order to increase the movement. They are to be inserted in the vagina (or even the anus) and their purpose is to strengthen the muscles that support them.
What you have to do is place them in a vagina (sometimes even for a day) and then do your usual business. Sure, it's a pleasurable sensation generated by the vibrating effect - due to the friction created by the smaller ball bumping against the wall of the hollow one. But its function is by no means to provide you with an orgasm. The Geisha balls' ultimate purpose is to develop the vaginal muscles and to increase your ability to control the vaginal movements. They have been compared to the Kegel exercises but for the lazy ones these are much more suitable. Just think - all you have to do is insert them and they just 'exercise' your muscles while you do... well... basically nothing.
Consequently, in a short while, both you and your partner will experience more intense orgasms and the whole sexual pleasure will be increased (trust me, the Geishas knew what they were doing). You may even
be able to perform little tricks in no time - like, for example releasing the balls and sucking them back in.
Apart from this pleasurable effects, they have positive effects concerning your health and are recommended by obstetricians and gynecologists, since the Ben Wa balls increase the vaginal elasticity and the bladder control. So, mild urinary incontinence (the involuntary excretion of pee that is) will be ancient history if you decide to use these toys. With these being said, knock yourselves out and give your partner the opportunity to experience some pretty damn awesome sensations.
