A woman shoves a filled water balloon up her vaginal tube, using it like a dildo. She then jumps up and down to feel the vibration of the water bouncing around. This is when the guy comes in.... the man begins to insert his penis in her vaginal tube and thrusts as hard as he can until it pops and squirts all over them. Then he has to stick his head up her vagina to get loose pieces of wet rubber. You would also use a water filled condom.
I just gave Fircoota a Wet Popper lastnite. She got freeky :)
