Experiment with slippery, messy, ass-filling fun with the Flow Fill silicone anal douche accessory, only available in the Kink by Doc Johnson by Doc Johnson collection. Flow Fill is crafted in the shape of a traditional tapered-tip butt plug with a hollow center intended for liquid play; just attach it to the anal douche bulb or shower hose adapter (sold separately) to completely fill that hole with lube, water, or other liquids of your choosing. Kink by Doc Johnson by Doc Johnson is an exciting collaboration with Kink by Doc Johnson.com to create a collection of high-quality authentic fetish items suitable for long-term practitioners and new initiates alike.
