(V). A means of sexual pleasure, Lower Wacker Drive (named after the street in Chicago IL) is when a man (on bottom in stated position) rubs his penis along the crevice of a girl’s vagina. In addition to simply rubbing his penis against the virginal crevice, he generally uses the girl’s fecal matter as a lubricant in this action. This is generally performed in the back of a moving car.
Well we picked up this hott hitch hiker and I couldn't resist giving her a Lower Wacker Drive.
