Let this butterfly take you for a ride! The Madame Butterfly 2 is a self-stimulating system that is waterproof. The kit includes an inflatable tube-pillow that can hold up to 300 pounds. A ribbed strap-on clitoral stimulator fits around the pillow and uses a removable multi-speed 2.25in x 1in bullet to provide you with varying pleasure and excitement. The controller requires 2 AA size batteries, not included, to get this butterfly soaring. The most comfortable pillow you will ever find!
