This position is basically a back-bend meets fellatio. It demonstrates the woman's athleticism while giving the man a very nice top-down view.
The position begins with the man and woman standing while facing the same direction with the woman four feet in front of the man. The woman then bends backwards into an arch until her mouth meets his manhood. For balance and leverage, the woman wraps her arms around his waist. She may also vary positions by holding onto his butt cheeks for added stimulation.
