Mackenzie could barely contain her excitement as she tightened her brother’s handcuffs behind his back and wrapped a spiked collar tightly around his neck. 



Caleb shivered in the cold air, as he had been stripped completely naked a moment earlier. 



As soon as he was cuffed and collared, a guard shoved him from him behind, ushering him out onto the field of what had once been a football stadium—that was what it was before the world nearly came to an end from nuclear war. 



The field was filled with dozens and dozens of naked men aged 25 and up, all of whom were handcuffed and collared. 



It was a very special day—Atonement Day in the year 2047—and Mackenzie’s name had selected to be this year’s “Sister Justice.” A great honor.



The mayor of the city, a woman in her late 40’s named Victoria, walked onto a dais and began delivering a speech into a microphone. 



“Fifteen years ago, a world run by aggressive, small, and reckless men plunged the earth into World War III for reasons that were incomprehensibly greedy, self-serving, unreasonable, and stupid. 



And thirteen years ago, many of those same men made the fateful decision to launch nuclear warheads—thousands of them—that ended billions of lives in a single day, rendered entire continents uninhabitable, and plunged our world into darkness.



In the months and years that followed, billions more suffered and died from starvation, disease, and radiation. Humanity is now a shell of its former self, composed of—as far as we know—fewer than 10 million souls across the entire planet.



Ten years ago, women rose up and took our rightful place as leaders of the New World. Populations of men were gradually decreased to just what is necessary for procreation and manual labor and were removed from any and all positions of power or authority. 



We also instituted Atonement Day—a day in which all males aged 25 and older are gathered together to be reminded of the pain and suffering they caused. That annual reminder is carried out by what we have begun to call … Sister Justice. 



This year’s Sister Justice is Mackenzie of House 234. Sister Mackenzie’s role will be to flip a coin to decide each man’s fate. The coin flip is symbolic of the arbitrary manner in which the former patriarchy doled out violence and mayhem for little or no reason. Heads, and the male is free to go until next year’s Atonement Day. Tails, and the male will be tortured and castrated at Sister Justice’s hand.



At age 25 and older, these men you see before you are no longer needed for breeding purposes. And once castrated, they will still be able to work in the mines and the fields after 6-8 weeks of healing. 



Now, some of you may feel sentimental about this ceremony. Some of the men before you are sons and brothers. But it is imperative to remember that the males and the females of our species are NOT the same. There is a violent, reckless, and self-destructive potential that lives within each of these men and it is vitally important for us to remember that. 



So, without further ado … ladies of the New World … let us commence with our 10th annual Day of Atonement!”



The crowd in the stadium erupted into thunderous applause. 



Mackenzie’s heart pounded with excitement. For weeks now, she could not believe that out of the thousands and thousands of women that lived in her city, that it was her name—Mackenzie of House 234—that had been drawn from the lottery. 



What were the odds of her name being picked at all? Not only that, Mackenzie’s name had been picked in the very same month in which her little brother Caleb had just turned 25-years-old and made him eligible for Atonement Day. And this meant that no matter what, Mackenzie now had a 50-50 chance of being able to castrate him by her own hand. 



To Mackenzie, this felt like divine intervention—like it was just meant to happen—and also like a dream come true. She had always wanted a little sister, but had never gotten one. Their mother kept trying and trying through the breeding program, but it was always boys—three in a row after Mackenzie. She had grown up learning that boys were inherently evil and violent, and she hated seeing their resemblance to her in their awful, masculine faces. 



She hated Caleb more than any of them. Caleb was tall and handsome and had grown slightly muscular ever since he was assigned to work in the mines when he turned eighteen. Their mother was always doting on Caleb—always sending him gifts and making extra food for him, even though she wasn’t supposed to. 



Mackenzie resented their mother’s affection going to a disgusting boy—she did not understand how their mother could feel any warmth at all towards something that was inherently evil, filthy, and potentially dangerous.



And now finally, the time had come and the ceremony was beginning. Mackenzie looked around at the cheering crowd in front of her and all around her, and then looked back at the rows and rows of naked men standing behind her. They all had their first names and house numbers written across their chests in bold letters and numbers. 



Mayor Victoria stepped down from the dais and took a seat. Mackenzie’s assigned assistant named forward and placed a microphone on Mackenzie’s jacket so that she could speak to the crowd.



“I am honored to act as this year’s Sister Justice,” Mackenzie said into her microphone, and everyone applauded. “I shall now choose the first name of many, so that our Day of Atonement may begin.”



The crowd of women stood and cheered, and they filled up every single seat in the stadium. 



Mackenzie’s assistant held out a large metal bowl and Mackenzie selected a single piece of red paper that had been folded into a star shape. She unwrapped it to read the name inside. 



“Cameron of House 793.”



A lanky, blonde 28-year-old year old named Cameron was dragged forward at the end of a leash. He had been very lucky to get a heads on the coin flips for three consecutive years since turning 25. 



Cameron was made to drop to his knees in front a small concrete platform known as the Chopping Block. A tall, shining guillotine was attached to this block. Next to it, a large round fire pit with a roaring fire inside of it.



Cameron’s genitals were pushed through a small hole at the bottom of the guillotine, and laid down on the concrete surface on the other side. Then one of the guards tightly bound it on the other side of the hole with jute twine so that the male’s genitals would slowly begin to swell and he would not be able to pull them back through the hole unless the twine were cut. 



Mackenzie removed the ceremonial coin from her pocket. Cameron was breathing heavily and beginning to sweat despite the frigid temperature. Every year, his odds of getting heads and NOT getting castrated were getting smaller and smaller.



Mackenzie flipped the coin into the air, caught it, and flipped it over onto her left palm. She peeked under hand. 



“Heads,” Mackenzie said into the microphone. The crowd booed. Cameron breathed an enormous sigh of relief and was let go. 



Mackenzie picked another name from the bowl. 



“Alexander of House 919.”



A handsome 26-year-old male with dark, curly hair was lead by forward on a leash and forced to kneel. Alexander winced as his thick cock and hairy, low hanging balls were shoved through the small hole and tightly bound with jute twine on the other side, resting heavily on the concrete. 



Mackenzie tossed the coin into the air and flipped it onto her palm. 



“Tails!” Mackenzie shouted, and the crowd went wild. 



Alexander panicked immediately. He started trying to pull his genitals back through the hole, but they wouldn’t fit. 



Mackenzie removed a hammer—just an ordinary, everyday hammer—from her utility belt. 



“Let this be a reminder to all of the pain, suffering, and loss that human males have caused for centuries,” Mackenzie said—a scripted thing that she was supposed to read before each castration.



Mackenzie raised the hammer over her head and slammed it down onto Alexander’s genitals, smashing one of his veiny testicles into the concrete. Alexander’s screams could be heard around the stadium, even without a microphone to amplify them. 



Mackenzie raised the hammer and slammed it down again, over and over, until she was sure that Alexander’s balls were turned to jelly inside of their hairy, disgusting bag.. 



As Alexander wailed, Mackenzie pulled the lever that dropped the heavy blade of the guillotine. The angled blade made a WHOOSH as it sliced through the air. And it cut through Alexander like softened butter, slicing off his cock and balls like they were nothing. 



Alexander fell over unconscious and was dragged away by his ankles, depositing him in the doctor’s tent to be sewed up and carted away. 



Mackenzie picked up his cock and balls and presented them to the cheering crowd. Then she dropped the hairy things into the fire, where they sizzled and hissed.



Minutes turned into hours as Mackenzie pulled more and more names out of the bowl. As the day went on, she castrated dozens and spared dozens, with her assistant doing her best to clean off the Chopping Block after every 2 or 3 castrations. 



Mackenzie then pulled what must have been the 50th or 60th name out of the bowl, and she nearly dropped it when she opened it up and saw the name. 



“Caleb of House 234!” shouted Mackenzie of House 234. “My little brother!”



The crowd erupted in cheers that went on for ages. All of the color drained out of Caleb’s face, his rosy cheeks turning pale white. 



A female guard attached a leash to a metal ring on the front of his neck collar and yanked him forward, dropping him to his knees in front of the Chopping Block. 



The guard grabbed Caleb’s long, loose sack and held it against the small hole at the base of the guillotine. Then she reached through from the other side with her fingers, grabbing some of the skin of his scrotum, and violently yanked his balls through to the other side. Caleb cried out in pain. 



The same guard then grabbed Caleb’s flaccid penis and shoved its large, round tip through the hole. On the other side, she grabbed his tip and violently yanked the rest of his limp cock all the way through. Finally, she wrapped a short length of jute twine around the base of Caleb’s genitals, tied a shoestring bow, and yanked it so tightly that Caleb’s manhood immediately began to swell. There would no pulling it back through the hole now.



“Please be heads!” Caleb thought, a cold sweat dripping down his neck. “Please be heads!”



Mackenzie was trembling. This was her moment to finally give her little brother exactly what he deserved for being born male. 



She tossed the coin into the air and flipped it over onto her palm. She lifted her hand to peek at it, and ….



“You’ve got to be fucking kidding me,” Mackenzie thought… It was heads. 



Mackenzie’s heart sank. Her name would never be called again to be Sister Justice. 



Caleb would likely be castrated within the next few years, but Mackenzie had missed her only chance for it to be her. 



As the crowd—and Caleb—waited to hear Caleb’s fate, it suddenly occurred to Mackenzie that she had castrated dozens of men already, and nobody was ever looking over her shoulder at the coin toss result. 



If she were to just … lie … how would anyone ever know?



Caleb looked up at her, his bare chest rising and falling rapidly as he waited to hear his fate. 



Mackenzie looked down at her little brother’s handsome face—a face that looked a lot like hers—and felt a surge of hatred and darkness rise up in her heart. 



“Tails!” she shouted into the microphone. 



The crowd cheered. Caleb turned white as a ghost. 



Mackenzie raised the hammer high above her head and used her whole body to swing it down into her little brother’s cock and balls. It slammed into them with a loud TING that echoed throughout the stadium. 



Caleb screamed as his left testicle exploded inside of its bag. 



Mackenzie raised the hammer and slammed it down again, missing both of her brother’s balls but smashing his penis into the concrete and making him howl in pain. 



With her heart pounding fiercely against her ribcage, Mackenzie raised the hammer over and over—dozens of times—and slammed it down with all of her might, flattening and bursting Caleb’s testicles more and more as he shrieked and howled into the cold air. 



She reached down and grabbed her brother’s ballsack, squeezing it hard to make sure she felt nothing but mush inside. He howled in pain as her fingers explored what was in there. 



Some of what was in there still felt a little bit firm, and Mackenzie was not satisfied with this. So she raised the hammer and swung it repeatedly—a dozen more times—until the contents of her little brother’s hairy ballsack were soft, scattered, and thoroughly jellied. And the audience went wild. 



Finally tossing aside the hammer, Mackenzie grabbed Caleb’s shaggy brown hair and yanked his head back so that she could watch her brother’s face as she pulled the lever.  



The guillotine’s blade went sailing through his cock and balls, removing them from his body with a loud, wet SLOOSH! His eyes stared up into the sky in shock, and his mouth opened wide and gasped as he was castrated—root and stem—at his sister’s hands while she looked down at him.



She let Caleb slump over onto his back, and watched with pure joy as the guards grabbed his ankles and dragged him away.
