When a man and a woman love each other very much, and can't decide between regular and anal sex they decide to compromise. This involves putting (carefully) the balls in her ass, and dick in her twat. This is best accomplished while in the "Pouting Frog" position. When finished, the easiest way to remove balls from ass, is using "Asian Dismount".
"Dude i was with this girl last night, and she wanted me to go Spelunking. The Pouting Frog was ok, but i think i crippled myself with the Asian Dismount"
