With the Fort Troff Piston Thruster, it’s all about the back-and-forth stroke to deliver the real feel of a hard pounding Top. Made of Premium Liquid Silicone, use with Water Based lubricants. While the Piston Thruster is not whisper quiet, we felt that an engine with a little roar was essential to deliver the thrust that piggy holes crave. With a stroke of 1.75 inches / 4.44 cm, this thruster nearly matches the stroke of big fuck machines. The super charged engines of the Piston Thruster deliver the power to drive deep. We made sure it’s strong enough to penetrate the tightest holes. The mushroom-shaped head is super soft n’ cushy, for easy entry. Controlling this power top is easy… use the remote or the buttons on the balls. You have 2 speeds of fucking which offer slightly faster versions of the basic stroke. Unlike traditional fuck machines, the Fort Troff Piston Thruster also offers 8 vibration settings. Powered by a state-of-the art lithium battery, the run time is around 45 minutes. USB rechargeable, it takes about 1.5 hours to recharge.
