B Ball Uno is a butt plug that reacts to your motions! B Ball Uno is shaped for easy insertion and ultimate comfort - and thats not even the best part!
With every movement, the small weight inside of the B Ball Uno create reactive sensations depending on the body's activity, allowing intensity ranging from gentle to powerful. The movement of the toy's weight does not require any electrical power and it delivers pleasure for hours whether during intercourse with a partner or as a little secret to carry around during the day. B Ball Uno gets to work without making a sound and thanks to its narrow base, it can be worn discreetly beneath the user's clothes. Its small size makes it an ideal beginner anal toy.
