The Sybian is probably one of the most terrifying devices that we own here at Insex On Demand. The ironic thing about this, of course, is that the Sybian is a vibrator, a device made to give pleasure. This machine, however, is so powerful and so overwhelming that some of our models would rather be whipped or electrified than be subjected to it. This is why, typically, we use it only as a last resort, building up to it over time with our models, but not this time.
