Deluxe vibrators can do all sorts of fun things that a real penis can't - but how many of them can simulate thrusting? The Ultra 4 Thruster has a thrusting motion, with the beads moving up and down with variable speeds. The 36 metal beads move up and down at 6 different speeds, while the beaver-shaped clitoral stimulator delivers external sensations through his flickering tongue. The clitoral stimulator has 4 functions (2 vibration speeds, pulsation and escalation), and an instant on/off button which allows the toy to be shut down easily. Glow in the dark controls. Batteries (4 AA) are included.
