Two Asian 18 y.o. teenagers are happily sparring to enhance their skills. As they are close friends, they talk of many things as they mockingly punch and kick each other. All is going well until the boy brings up the subject of which sex is the strongest in a mixed fight. The argument starts to get heated when the girl says that boys have balls that make them weak so girls can win. It’s the boys turn to lose his cool by lashing out his fist and hitting her face hard. She immediately pushes up against the ropes and knees him in the balls. She does not hit very hard because she now wants to enjoy his suffering as she repeatable targets his balls throughout the fight. Now the poor boy has a nice little bulge as a target for his girlfriend who takes great advantage, enhancing her pleasure and enjoyment as a winner over a boy.

The teenagers have forgotten about the rules of sparring and it has turned out to be the great battle of the sexes. The boy’s girlfriend feels much insulated at being told that she is the weaker gender of the human species. She is about to change and gives him a soft knee blow straight up into his balls, and Wow, did he not get a painful surprise. His knees sagged as the pain migrated into his belly, then his temper flares. He swings his arm, closing his fist tightly hoping to knock her out. However, she was to quick and ducked down so his arm swung harmlessly over the top. Before he could correct himself, another hard blow hit him straight up into his balls. This was a kick this time, it hurt even more, and he collapses to the ground. She starts to enjoy inflicting pain into his balls and proving to him as a mere male being make weak by a girl attacking his balls. She now knows how to control her boyfriend so he will be submissive to her. The girl kicks him in the groin several times and while his head is low, she kicks a few, not so hard blows around his head. She is starting to feel turned on with sexual feelings as she kicks him in the balls from behind. She is deadly and accurate with her kicks and she starts to feel as though she is a supreme girl, being all-powerful over boys. As he hangs on the ropes close to the floor, she kicks him hard into his back to stand him up. The teenage boy stands and turns to face her and then the girl knees him again, but this time it is a double whammy as she lands an uppercut to his chin at the same time her knee flattens his scrotum. She spins around and executes a backward kick lands with deadly accuracy up into his balls. Her crotch tingles with excitement and bulges with the pleasure as she experiences having absolute power over her boyfriend. The girl turns to face the boy and she notices his groin bulge is a little bigger than it was. She starts laughing and teases the boy, calling him the male weakling. The boy is now out of control with rage, swinging his fist wildly trying to bring her down. She elbows him in the face and knees his balls at the same time to show him as a girl that she is the boss. Her crotch, now throbbing, wet and slippery gives her the urge to have some fun by dancing and kicking his balls in ballet style. She does a backwards flip and hits his balls yet again with her boot. This time the boy was down for the count but manages to get up in due time. As she watches the boy, she noticed that now his groin bulge had grown even more. He sinks to the ground again with his hands cupped around his groin to ease the pain and to hide his ever-increasing bulge. The girl looks at the kneeling boy aware that he may spot her wetness, but she was proud, as a supreme female and it would show the pleasure was all hers in physically dominating the boy. Girls have boys curled at their feet as they win the battle of the sexes.
