Some women can in a real fight defeat your very manhood by kicking with such precision and speed that they can decide which testicle the doctors will be trying to save one or two hours after you went down screaming and crying.
I am a tall and big Danish guy. There are small, pretty and big-boobed martial arts women who can defeat me in a real fight with a single kick rupturing my right testicle. That very fact makes me cum so hard it actually hurts my left testicle.
