The Satisfyer Pro 4 Couple is a compact couples vibrator curved to fit her body. Worn during sex, she gets extra stimulation to her clitoris and G-spot while he enjoys the vibrations too. The insertable portion provides ten modes of vibration to stimulate the G-spot. The external part rests on the clitoris to provide eleven levels of touchless stimulation via pulsating pressure waves. Thanks to the control buttons located on back of the unit, you can choose the vibration and pressure waves separately, which allows for countless possible combinations. The USB rechargeable Satisfyer Pro 4 Couple Stimulator is waterproof for fun in & out of the water and easy cleanup.
