The secret? Two small, weighted balls within each of the bulbs of the plug. These free-moving balls move freely with the smallest movement. Even the gentlest walking motion will set these internal, whisper-quiet balls on the move. The constant movement ensures you can never forget about the sensual plug nestled between your cheeks - and no one around you will be any the wiser.
Crafted with a unisex design, the tapered design of the B-Balls Duo allows for a gradual insertion. Perfect for long-term wear, the slim T-shaped base fits safely and snugly between the cheeks. With a fully waterproof design, this pleasurable butt plug is a breeze to clean.
