With a stroke of just under 2 inches, the Tendril Thruster nearly matches the stroke of big fuck machines. The super charged engines of the Tendril Thruster deliver the power to drive deep. We made sure its strong enough to penetrate the tightest holes. The mushroom-shaped head is super soft n cushy, for EZ entry, and the tendrils give extra stimulation. Controlling this power top is easy use the remote or the buttons on the balls. You have 2 speeds of fuckin, which offer slightly faster versions of the basic stroke.
