While performing intercourse the male inserts his penis into the pussy for one stroke, then into the anus for one stroke... Repeating as necessary and increasing speed to resemble a sewing machine.
(noun or intransitive verb depending on usage) The positioning of a woman while enjoying sexual intercourse with a man. The woman sits atop her man straddling him facing towards his feet. Needless to say the man is laying on his back facing now towards her backside. Through this process she rides him with equal dexterity as though she were a thoroughbred jocky, much like the well acclaimed Willie 'The Shoe' Shoemaker
Chris: Hey Eric so how was your date last night with Jennifer?
Eric: Cool, dinner was alright..bad wine, but the night improved because Jenny did the "Willie Shoemaker!"
