Not to be confused with the motor boat. The Boat Motor takes place during the act of cunnilingus. When the vagina becomes sufficiently moist the male makes a buzzing sound with his lips, much in the way you would blow into the mouthpiece of a trumpet. For greatest effect, couple with the Tidal Wave.
