Using the Womanizer ( http://www.womanizer.de/shop?___store=en&___from_store=en )who works like a air depression device, there are no vibrations, I am pretty sure that no one woman can hold on, use it without having a orgasm in a very short time. There is no physical contact between the clitoris and the device.
Some T-Shirts shows " Hike or Dye "
Using this device is like " Cum or Scream and cum "
I have a 50 years long experience in vibrators, I never used a such pleasure device.
Expensive , yes it is, you will enjoy your expenses, use protections for your matrass and sheets ladies, it will make you squirts all the fluids you have, and make you dry, until recovery.
If the Hitachi Magic Wand and the Eroscillator makes you orgasm by contact with your body, the Womanizer will make you cum by reaching your erotic soul, and awake it if it was sleeping, bringing to a second life if it was dead.
