With the touch of a button, those 4 thrust modes we mentioned activate, sending the pussy thumping and pulsing up and down. Just in case that's not enough to take you flying over the edge, the Thrustbuster is packing a very sexy audio surprise. A separate button shaped into a pair of lips starts up some orgasmic moaning, panting and oral encouragement. Rechargeable via USB and complete with padded travel pouch, the Thrustbuster is definitely portable and always ready to play. 3.5 hours of charge time will provide up to one full hour of playtime. Not rated for use in water.
