When a guy/girl bends over like a monkey/gorilla at the end of a diving board, wearing a flash outfit with a hole in the bung. Then a man at the bottom of the diving board runs up and sticks his penis into the guy/girls bunghole, rolling into the water making a huge splash while doing it.

"Because I was doing the thunder plow with some hot prostitute."
