stove pipe
A sexual position that is performed from a classic missionary style, from which the girl raises her ass in the air , and clutches her knees to her breasts.  With the vaginal crevace aiming skyward, the man will step over her, aim his weiner downward at the vagina, insert it, and squat up and down as to provide friction that would result in the eventual spurting of the wang.  A stove pipe can also be performed using the asshole and the weiner.  This is also called a stove pipe.
