Fun Factory B Balls Anal Plug

B Ball Uno is a butt plug that reacts to your movements for extra pleasure and sensation thanks to the small weight inside.


This weight inside this anal sex toy bounces, rolls, and rumbles in response to your movement, allowing extra sensation and intensity ranging from gentle to powerful.

Using the same technology as the Fun Factory Smartballs, the movement of the inner balls creates a new type of anal sensation. It stimulates the anus and surrounding erogenous zones during foreplay or sex for anyone.


  • Wear it during vaginal sex for an extra feeling of fullness: its round shape will angle your partner (or favorite luxury dildo) into your G-spot.
  • Press a luxury vibrator against the base, and feel the ball inside respond! 
  • It can be worn as a little naughty secret to carry around during the day. It is quiet and thanks to its narrow base, it can be worn discreetly beneath your clothes. 


Shaped for easy insertion and comfort, B Balls Uno is an ideal beginner anal sex toy thanks to its small size. 


Made with premium silicone, we recommend using Fun Factory B Ball Uno with water-based anal lubricant and cleaning them before and after use with sex toy cleaner.
