Experiment with slippery, messy, ass-filling fun with the flow fill silicone anal douche accessory, only available in the kink 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.
Care and Maintenance Instructions: Spray with Doc Johnson Toy Cleaner, wash with mild soap and warm water. Allow to dry completely before storing separately from other toys in a cool, dry place. Use with water-based lubricant/glide. *Toy Cleaner sold separately.
