“You got it!” said Chelsea as her strong, athletic leg kicked upward with all of the force she could muster. She had no intention of holding back. A part of her was desperately wishing to her the sound of two “POPS” when her foot landed. In what was only a split second, her hard, unforgiving Mary Janes landed perfectly onto the bulge between Bobby’s legs. Coming in an upward angle, the hard and wide toe of the shoe captured both of his precious orbs and pressed them mercilessly into his pelvic bone. The force of the kick was such that Bobby’s feet almost left the ground, only the tip of his big toes remained on the floor. This meant that his own body weight was working against him, and he felt an unbearable pressure in a region of his body that he had never even give much thought to. He was in absolute shock.

For Chelsea, that moment had returned. That fleeting feeling of absolute paradise as the boy’s face contorted into an expression that it had never before made, twisted as it was by the overwhelming feelings of shock, pain, and utter terror. In Bobby’s face she also thought she saw a hint of betrayal – she was his sibling after all, his blood. How could she do this to him? This truly was the worst thing that had ever happened to this boy in his short and sheltered life. And it was all thanks to his older sister, someone who was supposed to love and protect him.

Something else was different for Chelsea this time, too. Before she had been a witness to the bust, now it was her foot between his legs, it was she who was the cause of this torment for the male victim.

These two facts only multiplied the pleasurable sensation overcoming her, and her knees actually buckled a bit as her kicking foot returned to the ground. She had to steady herself from falling.

Cynthia, too, was experiencing that same feeling as she watched her son’s face. It had been too long, she thought, as this familiar high came back to her. She was also overcome by pride, having just watched her daughter be initiated into the wonderful world of ballbusting. And this was not any male victim, this was her son. This moment would always have a special place in her memory as she sought to capture that expression on his face.

As before, Chelsea noticed that the first thing to snap her out of her daze was the loud, high pitched screams of the tormented male victim. Bobby collapsed to the floor, grasping vainly at his balls in attempt to relieve the pain, and sounding more like a girl than Chelsea did with his high pitched wailing. Again, the wave of satisfaction surged throughout her body as she watched her victim roll, writhe and scream. She thought it was so amusing how he did everything he could think of to relieve the pain, since clearly nothing would work. He clearly did not fully comprehend the reality of his existence yet. He was a boy, and as such a prisoner to his own testicles.

It was this amusing thought that caused her to giggle. Her mother joined in, and soon the two burst into hysterics. The fact that this was her brother writhing on the floor, and that she was sharing this experience with her mom, made it even more intense for Chelsea. Her sides felt like they would burst with laughter, and partly as a result of that, and partly in a desire to mock her brother further, she fell to the floor beside him and rolled and writhed, grabbing at the area between her legs. Only of course, hers was nice and smooth.
