Naghi No 38 is a duo vibrator with 2 powerful motors, one in the sturdy shaft that has a big rounded top, the other motor in the butterfly with its soft wings and teasers to stimulate the clitoris. Apart from the 10 vibrations to choose from (being 3 levels of steady vibrations and 7 different rhythms), the top of the shaft can make rotating movements as well, in 3 speeds. You may find this super exciting and be warned, it may cause G-spot orgasms! Use the third button at the base of the vibrator to start the escalating mode, which is an acceleration boost. When you push this button the vibrations will immediately go to the highest level.
