Imagine all the ways you can fill up using this 2-in-1 hollow plug! The large anal plug is made of soft silicone for a silky-smooth insertion. Your sphincter will come to rest on the bold ridges of the stem, providing extra stimulation. The open core allows you to get creative, further filling yourself or your partner with an enema hose, lube, and more! Once you are at maximum capacity, the solid core fits snuggly and securely, sealing the plug up! Made of premium silicone, this toy is non-porous and phthalate-free. Clean with mild soap and warm water and avoid use with silicone lubricants.
