Hawiian Hydroplane

Although quite a difficult and messy manuvure, the Hawiian Hydroplane involves a girl laying a diarreha onto a slip'n'slide, making sure to cover the whole slide, then proceeding to sit nude spread eagle on the end of the slide. Then the man, also nude, sprints a short distance and slides down the 'reha laiden slip'n'slide on his knees with an erection, positioning himself in a way to where his penis can enter the girls snatch upon collision at the end of the slide.
