This sexual act requires 4
people: at least 1 guy and 1 girl; most preferably 3 guys and 1 girl due to the physical strength required. A Kellner Washing Machine (KWM) is preformed by having one guy standing in a pool with his penis in the girl's pussy and she is curled up in a ball so that the 2 remaining
people can spin her around and back and forth, sloshing the water around as in an actual washing machine. The girl
may want some good goggles. Depending on the guy and the spin methods employed, the girl
may also need a breathing apparatus.
I got the most amazing KWM (Kellner Washing
Machine) in my pool last weekend. I didn't know
Lauren could hold her breathe that
long. It wouldn't have been possible without her friends Christina and Niki.
