When a man pumps a slip n slide with lube instead of water and a woman sits at the opposite end of the slip n slide with her legs open. The man then runs, jumps onto the slip n slide, and tries to do the coolest pose he can as he slides down the slip n slide. He slides all the way to the end, using his speed and force to penetrate the woman at the end.
