We have probably all had what I call "The Call of the Balls." It's that feeling when your balls are tingling and you need to bust a nut. If you are home alone, then you can whip out your cock and have a go at it, but it can be torture if you are in public and can't bust a nut. Then again some people will do it anyway. The best is on a long road trip while you are alone in your car, the call of the balls comes, and you can just whip it out. You can even give the truckers a show. You know whenever and wherever the call of the balls comes, you've got to answer the call.
