18 y.o. Sister and brother are home alone and should be doing their homework. An argument starts and as usual, the subject is about which sex is smarter, or stronger and able to overpower the opposite sex. The argument drifts to a new topic on the weakness of boys having balls. The argument continues until they decide to settle their dispute by fighting outside on the grass. Will the boy win by his brute force or will the girl win by using her feminine skills of defense by attacking his balls.

Nelly says: "I'm a ballet dancer and one time in partnering class we were doing this really hard lift. He lifted me up, something went wrong, and I kicked him in the balls! Typically, girls kick guys because they want revenge! The guys are in so much pain and they make funny expressions. It's a key to victory in all wrestling matches against my brother!"

Bob says: "Week ago I was playing with my girlfriend. I would get on all fours and she would climb all over me and try to get me down. She was wearing a long sleeved leotard and ballet shoes. Once though, she tried to kick my butt and was a little low. She kicked me solidly in the nuts. It was like I was hit by a truck. I had no idea how bad a kick in the nuts was like till that hit. The game was obviously over. Bad luck, my sister Nelly witnessed my shame. Now she attacks my groin each time when we wrestle each other, oh God, it hurts so much!"
