Sybian machines are a favorite running gag on the Howard Stern show, and for good reason. They're designed to be ridden and used hands-free. Because you can change the different attachments and motions, it is a highly versatile toy. At the most basic level, they're great toys for clitoral stimulation, and you can change the attachments to take advantage of the rotating and vibrating actions. There's also a world of potential for the bondage crowd. Imagine being tied down to one of these things! This toy is definitely an investment in pleasure, and well worth the money you'll pay for it!
