Of course you can use this to flog anything, not just balls. However this is a classy and very versatile BDSM toy that you have to try on some willing balls.
Perhaps you've heard the phrase, "This space is so tight, you can't swing a cat in here". It originates from the 18th Century British Naval punishment of a cat o'nine tails. A cruel torture implement very similar to this one here, and if used repeatedly on a pair of balls they will be glowing red in no time at all!
