The Fun Factory Bi Stronic Fusion is a rabbit vibrator that offers pulsating thrusts with external fluttering vibrations. The large size and girth offer an excellent simulation of thrusting perfect for vaginal or anal play. It has two arms — one for penetrative action and one for external clitoral stimulation. It’s penetrative arm is a ridged 4.1-inch shaft. It’s made of silicone that feels silky soft on the skin, and has a forward-leaning head that can massage the G-spot. Its external arm is a flipper-shaped stimulator meant to encompass the whole clitoris. This product is compatible with water-based lubricants.
