Where when a person is about to cum they put there balls into a small container of cold water to keep back the cum. Eventually after doing it many times the person can't hold it back so it seems like it's a never ending shower of cum.
Bobby: Yesterday I had a good never ending shower going and it took like 5 minutes to finish!
