The Pythagoras position is where 3 people engage in oral and traditional sex while in the shape of a right triangle. One person lays on the ground and fucks one person and eats our the other person. The people on the top of the position make out. This produces a right triangle shape, hence the name, Pythagoras Position.
*note: requires one male
*note: can be done in both a vertical or horizontal position
Jane, Beth, and Billy created Pythagoras Position last night.
