Douching had never been easier with the Nasstoys Electro Douche! Simply fill the bulb with water, firmly twist on the auto-spray nozzle, comfortably insert using water-based lubricant, then press and hold the power button to begin douching. No more squeezing a bulb and no more back flow! The user may refill the bulb and repeat the douching process as needed. Please clean before and after each use with toy cleaner. To charge, please insert the pin charger into the back of the douche nozzle.
