That's hard enough to provoke a superb ejaculation! The effect lasts from several minutes to more than two hours if the beating is followed by frictions with stinging NETTLES. I may ascertain that because my genitals were flogged twice a week by my lovely 3rd wife during some eighteen years. Such a good treatment was always IN PUBLIC every Saturday afternoon...
Oh yes ! the wife of this lucky man is slapping very correctly her husband cock which is perfectly able to regularly endure such a healthy so favourable session !
