Tasmanian Helicopter

The female member of a heterosexual partnership proceeds to maneuver into a head stand position next to a bed or other object which one can stand upon. Then she will follow by spreading her legs into a split. The male will then stand upon the aforementioned device used to stand upon and will slowly insert so as to balance precariously upon his penis. Finally, the man will start to spin as the female hums an engine sound. The male body will resemble helicopter blades. Mission accomplished.
