A standing sexual position in which the man is behind the
woman, who is bent over with her hands cuffed behind her back. As the man "pumps", he moves the
woman's arms up & down, while putting his finger in her ass. At the moment of climax, the man pulls his finger out as the
woman simultaneously ejaculates and shits.
While vacationing in Antigua, I hired a tuba
player to come back to my hotel room and
play while I gave my wife a Guatemalan Water
Pump.
