Story about taekwondo girl
I hope you can help me with this. I''m looking for a story about a girl in taekwondo class, who enjoys kicking the sparring partners in the nuts. If she discovers that the boy is'nt wearing a cup, "accindetaly" kicks him in the nuts. There was a phrase about their "happily waiting balls". The title was about "Being a girl in taekwondo class", or something like that.
