bow thruster
The act of taking a woman out on the water in a boat. When you find a desolate or suitable area of open water configure the controls to make the craft spin in circles or make a broad arcing maneuver. After the controls are set bring the woman to the front of the boat and tie her hands either in front of her or behind her back. Set her on her knees and proceed to fuck her face until you blow your load.
Took my wife out on the water last night. I gave her the ole bow thruster If you know what I mean.
