The Merci Power Banger Fuck Machine delivers superior power and endless deep pleasure. The adjustable thrust arm of this powerful machine can be set to give you exactly what you want in all your favorite positions, while four strong suction cups at the base securely hold the machine in place. With the speed controller, you have full control: the variable speed controller allows you to adjust the thrust speed from 28 to 195 strokes per minute. The included Vac-U-Lock plug enables compatibility with attachments from Doc Johnson's Vac-U-Lock and Signature Cocks series, as well as all other VUL-compatible attachments.
