A firend of mine told me a buddy of his was reading an article in Playboy once (how’s that for a cite?) which told the supposedly true story of a couple who had sex while water skiing. She bent over, he zoomed up behind her and the rest I’ll let you figure out.
Jesus. I can barely stand on those things when I’m by myself. I can’t imagine how good you would have to be to get that close to a person without falling - nevermind keep your soldier at attention and finish with a happy ending. Tricky stuff.
