Fun Factory B Balls Duo Motion Anal Plug Grey/Black

Fun Factory B Balls Duo in Grey and Black is a hybrid of anal beads and a butt plug, with rotating weights that react to every step or thrust. This motion anal plug needs no batteries or charger: the two balls, 3.2 cm and 3.6 cm across, are inserted one at a time, and the weights inside turn as you move. The result is a silent, filling sensation that suits confident anal players during sex, solo play or discreetly through the day.

Key Features

• Reacts to your rhythm: Inner weights rotate with body movement for sensations that build with activity.
• Beads meets plug: Two graduated balls ease in like anal beads and stay in place like a plug.
• Totally quiet: No motor means no sound, so you can wear it wherever you like.
• Discreet base: The narrow base sits comfortably between the cheeks and is hard to detect under clothes.
• Partner-friendly: Worn during intercourse, it adds anal stimulation for any gender.

How to Use and Care

Relax, use a generous amount of water-based lubricant and insert one ball at a time. Remove slowly by holding the base. Always clean anal toys before using them anywhere else.

Wash in warm water with a mild soap or Fun Factory cleaner, rinse well and allow to air dry.

Secure checkout and a plain, unbranded box come as standard, with delivery available to the UK, Ireland and the rest of Europe within the EU.
