Naked water
Naked water-skiing is when you take your clothes off, grab your board, and try not to fall in the lake. If you’re a guy, you might get a hard-on. If you’re a guy who falls in the lake, you might get a hard-on and a cold shower.
My uncle went naked water-skiing and got stuck in the lake. He came out screaming and still had a hard-on.
My friend took a naked water-skiing trip and got hit by a wave. He ended up with a hard-on and a sunburn.
My dad went naked water-skiing and got so hot he turned into a human sauna.
