Setting the stage

"There's a lot more cars here then I expected..." Billy said as he looked at the surprisingly full parking lot when they pulled in to the gym. "I thought it was just gonna be club members...?"

"Maybe some of the guys invited friends or girls. Wouldn't be the first time we snuck a party behind Coach Henry's back," Matt replied as he killed the car and climbed out. "Like I said, whatever helps you out, right?"

Despite his kindly response, Billy noticed the sharpness in Matthew's voice, but he couldn't fault his friend after he had snapped when Mattie just wanted to help. He simply sighed and accepted this answer, though his heart fluttered at the thought of more women invading his sacred boxing sanctuary. He wasn't sure how he would handle the two in proximity to each other without panicking or sneaking off for relief, but he couldn't exactly back out at this point. Instead, he just followed Matt to the entrance.

Inside, the atmosphere was electric. The gym was packed, but not with the usual crowd of hobbyists or serious competitors. No one was dressed for a workout. It was like the scene of an underground fight club, complete with a crowd that erupted with excitement as they walked in.

At the far end of the main ring, an energetic, imposing figure caught Billy's eye.

Billy froze mid-step, his breath hitching in his throat. There she was. Carly. She looked completely different than the person he remembered running out of the club years ago. The weak, flabby girl who was so desperate for recognition had been replaced by a proud, athletic amazon. She stood tall, radiating a confidence that seemed to fill the entire room, her presence commanding attention from everyone nearby.

Billy couldn't believe how incredible she looked in that moment. The skintight orange booty shorts she wore outlined her huge, muscle-packed glutes and left every inch of her powerful thunder thighs on display. Carly's small, but perky breasts were proudly packed into a matching orange top. Her eyes met Billy's as he froze, and she grinned with wicked delight.

A wave of pure, unadulterated dread washed over him, but beneath it, that treacherous heat flared up again making his manhood stir in his shorts. His pulse hammered against his ribs. He felt like a deer in headlights, just waiting to be run down by the fiery kickboxer.

"Oh god," he whispered, almost to himself, his knuckles whitening as he gripped his gym bag. "M-Mattie...? Wh-what's going on...?"

Matthew stopped walking, turning to look at Billy with a grim, knowing expression. He didn't try to sugarcoat it this time. The camaraderie was gone, replaced by a stark finality instead.

"You know exactly what's going on, Billy," Matt said, his voice uncharacteristically cruel. "We're here for the main event."

He gestured toward the ring, where Carly was currently pacing like a caged animal that knows it's about to be unleashed. Every step she took caused those massive, sculpted thighs to flex, drawing the eyes of half the men in the gym.

"You guys got interrupted the other day," Matt scoffed, putting his hand on Billy's shoulder, but not in a comforting way. "Tonight, we get to see how it would have played out."

Billy felt the blood drain from his face, leaving him pale and clammy. The weight of Matt's hand on his shoulder felt less like support and more like a shackle to keep him from fleeing. The realization hit him like a freight train. This was never about helping him. He'd been set up to fall.

"Th-the main event...?" he stammered, his voice barely audible over the roar of the crowd. He looked around frantically, seeing faces he recognized. Fellow boxers, classmates, some women he'd met from Anna's feminism club. All waiting for him to climb into the ring.

"You set this up?!" Billy gaped at his best friend, not bothering to hide the hurt disbelief in his voice. "Why...?!"

Matthew didn't blink. He didn't look sorry. He just placed his other hand on Billy's free shoulder, fully trapping him in place. He leaned closer, his voice cutting through the ambient noise of the gym like a razor.

"You don't get to act like this is a betrayal," his rival said with harsh coldness. "I always had your back. For years, no matter how much people overlooked me, I let it slide because we were a team. Even when you became the champion and started treating me different, I still had your back. Even with what it cost me..."

Matt gestured to the ring where Carly was waiting, bouncing from foot to foot as those deadly legs pulsed with power.

"But that wasn't enough for you," Matthew growled, finally releasing all the subdued pain and anger that had built over the years. "You cost me Carly, you don't give me credit for my skills or my support, you talk down to me in front of the other guys, and you lied to me about Anna! You knew we liked each other, but you told me she was gay just so I wouldn't ask her out! That's TWO girls I liked that you decided I can't have...!"

Billy stared at Matt, his jaw dropping. The allegations poured out of his friend like venom, stripping away every excuse he’d ever used to justify his behavior. He hadn't just been arrogant, he had been manipulative. He had treated Matt like a sidekick instead of a brother, and he had lied to keep both Carly and Anna out of reach.

"Matt... I... I didn't mean to..." Billy started, but the words turned to ash. He looked at the floor, unable to meet the brawler's piercing glare.

The truth was, he had been selfish. The undefeated champion had enjoyed the feeling of being the best, and had not been nearly as supportive of Matthew as his friend had been of him. He would rag on him in front of the others just for that tiny swell of pride from feeling superior. And while he had never intended to cause Carly and Matt to break up, he was always quick to remind his friend about her attitude towards the end to ensure they stayed apart. What was worse, Billy had no defense against the accusation involving Anna. The champ had lied for purely selfish reasons, not liking the idea of sharing his best friend with his nerdy little sister.

When Billy couldn't find words to defend himself, Matthew let out a harsh, cynical laugh that lacked any humor. He knew that his friend had finally realized the depth of his own betrayal, and that Matt's actions were justified. He stepped back, giving Billy space, clearing the path to the ring.

"There's no backing out of this, Billy," Matt smiled, a real thrill running through at the dynamic he held for the first time and the battle to come. "Everyone here came to see this rematch. They've seen you. Walk away, and everyone will see you run. Even if you tell them you were tricked into coming, they'll all know that you are scared shitless of Carly."

The crowd was a sea of expectant faces and eager voices. Some were cheering, others were whispering, but all eyes were fixed on the towering, sweating mass of muscle that was Billy. Above them, at the center of it all, Carly waited in the ring. She beckoned him forward with a predatory grin, slapping her gloved hands together.

Billy was trapped. Between Matt's icy stare and the roar of the crowd, there was nowhere to run. If he walked away now, he wouldn't just be losing a fight, he'd be forfeiting his reputation, his title, and every shred of respect he had left. He'd be known forever as the coward who ran from a woman.

His eyes drifted back to the ring. Carly was practically vibrating with anticipation. Those orange shorts hugged her curves so perfectly it made his mouth dry, and the way she slapped her gloves together sent a jolt of electricity straight to his crotch. He hated how much he wanted this. He knew how important it was for him to win, and yet he quivered at the idea of her overpowering him.

Billy gulped, his voice trembling slightly. "Fine."

Matthew gave a curt, satisfied nod, and gestured down the path of spectators. He watched as Billy slowly, reluctantly, began to move toward the ring, like a prisoner being led to the gallows. The walk felt miles long, every eye in the gym watching the champion's timid approach. Everyone who knew the confident, unbeatable boxing prodigy could barely believe that this was the same man.

As Billy climbed through the ropes, he looked across the ring. Carly was waiting for him, barely containing her excitement and wearing a smirk that screamed triumph.

"Took you long enough, big guy," Carly teased, her voice loud enough for the front rows to hear. She bounced on the balls of her feet, her thick legs flexing with every movement. She looked ready to tear him apart.

Too nervous to meet her eye right now, Billy looked out at the crowd. Most of his clubmates were here. Some looked surprised to see him cowering so much, a far cry from the unstoppable force they had always known. Others looked elated, hoping to see the man that none of them could dream of beating finally laid low. The idea that it might be a woman that finally did the deed, the very first knockout he'd ever delivered, somehow made it all the more exciting.

It didn't take him long to find Anna, right in the front row. Of course she was here. His sister had a smug grin on her face as she looked up at him, as if she knew his defeat was imminent.

Next to her was Anna's best friend, Kristen, which actually horrified Billy even more. Despite being such an introverted nerd, Anna had always had a loyal and outgoing friend in Kristen. The buxom blonde babe had developed a rather substantial following on TikTok, and was already recording everything, making the champ pale at the thought of this going viral.

Billy looked around again, and sure enough, others were already taking pictures and videos as well. This was SO much worse than his loss to Karen! At least with her, only one video existed, and there was a chance everything would just blow over or disappear if he stayed in line. But this...? Win or lose, this match would be all over the internet tomorrow.

Billy tried to take relief that this fight would have no official standing. Even if he lost, even if he was humiliated, even if Carly managed to find her way to his chin and to night-night him, it wouldn't affect his spotless record!

But he knew that mattered little. With all these people watching, recording, ready to post the destruction of his legend at the fists of a thick thighed feminist...

He would be finished. He would be ruined. He would be broken for the entire world to see...

His dick throbbed.

Matthew climbed into the ring. With his standing as one of the best boxers around and his connection to both competitors, he was a natural referee. He gave Billy a look, a casual, friendly grin that he'd shared with his rival so many times throughout the years, but held a whole new meaning tonight.

"Get ready," Matt said simply before pulling out a microphone to address the assembled crowd. "LADIES AND GENTLEMEN! WELCOME to the MAIN EVENT!!!"

The roar of the crowd was deafening, a wall of sound that crashed over Billy and made his ears ring. Even his championship matches didn't get this kind of response! Why were so many of them here? They couldn't have had much notice.

It hit Billy punch in the gut that they were all here to see if he would really lose to a girl. They wanted him to lose! He tried to focus on his breathing, to tap into that old championship mindset, but his body was betraying him. His palms were sweaty and his knees felt dangerously weak, all while his meatstick threatened to show everyone how turned on his opponent was making him.

"GET READY FOR THE REMATCH OF THE CENTURY!" Matt said enthusiastically, his voice booming through the ring speakers, amplifying the hype to a fever pitch. He pointed to Carly, who was eagerly bouncing on her toes, her massive quads exploding with might even from the simple movement. "In this corner... the challenger who proved that size and gender doesn't mean squat... "MANKILLER" CARLY!!!"

To her immense shock and pride, a roar of approval came from the audience. Not just friends or feminist supporters, but several of the boxers who had once sneered at her with disdain. Who had mocked her for trying to compete in a "man's sport." Those who had doubted her, belittled her, made her feel worthless, were now chanting her name, urging her to dethrone the champion...

Billy swallowed hard, his throat feeling tight and parched. Hearing that nickname, "Mankiller," sent a fresh surge of heat straight to his groin. It was humiliating, absolutely degrading, but God, it was working! He could feel his cock twitching painfully against the fabric of his boxing trunks, a shameful reaction to the sheer dominance radiating from the woman across the ring.

"CARLY! CARLY! CARLY!"

Billy's stomach churned as he heard the chants. Hearing his peers, men he respected, men he had trained alongside, all of them cheering for his downfall was a special kind of torture. It felt like a mutiny, yet as Matt had proven, one the champ deserved.

He stole a glance at Carly. She was soaking it all in, her head held high, looking absolutely incredible in her orange gear. Every time she shifted her weight, those gams strained against the fabric of her shorts, reminding him of how much power she could produce. Billy couldn't ignore the outline of her abs or the swell of her biceps as she waved at her new fans. With her figure packed full of all the muscle she had clearly worked so hard for, Carly might just be the strongest of the women that had humbled him, and the only one who had yet to put his lights out.

That thought made him gulp. She was the only one that remained. If he lost tonight, in front of all these people, he might truly be finished. He might never be the champion again. Every woman he'd faced would have completely crushed him, and the world would know, and he'd have nothing to hide behind.

Those white gloves Carly wore weren't the lethal blue weapons that his mother and sister had used. He couldn't pretend he had underestimated her like Karen. He couldn't act like this would be a lucky shot in training like with Lucy.

Billy knew what Carly was capable of. He knew she wanted his head. He knew he had every advantage in skill, size, durability, and power. And yet he was scared of this frizzy-haired feminist. Because he knew that this might be his last chance to prove he wasn't washed up. If he lost, Carly would be the champion in all but name, and Billy would be her bitch...

...and that thought made his dick throb once more...

Matthew raised his arms, silencing the crowd with the gesture.

"And in this corner..." Matt continued, his voice dropping to a lower, more dramatic register. "...the undefeated champion. The man thought, until recently, to be unbreakable... BILLY "THE IRON CHIN"!!!"

The chant for Billy was significantly quieter than the one for Carly, lacking the fervent energy of the crowd. It was respectful, perhaps, but it was hollow. The most significant reaction he got was when he removed his shirt, a few women (and men) cat calling at the sight of his sculpted body and bulging muscles. It didn't do much for Billy's confidence now that he knew the truth. People were here to watch a king fall, not to celebrate his reign.

"This exhibition bout is best of three rounds," Matt announced, his voice firm. "The match will end if a combatant cannot stand before a ten-count, admits defeat, or is knocked out."

The crowd cheered it's approval. Matthew dropped his hands and walked over to Carly while Billy put his gloves on. He made sure her own were secured and spoke where only she could hear.

"You got this babe," Mattie said with a grin, showing how proud he was before switching to a more serious octave. "How do you win?"

Carly smiled back, repeating the words her boyfriend had drilled into her all day yesterday. "I'm not stronger, so don't try to be. I'm faster. I'm smarter. I'm harder to hit. Use it."

"That's my girl," he winked, his grin getting a bit more playful. "Want a kiss for luck?~"

Carly giggled and winked back. "Anna already took care of that, but Billy looks like he could use one~"

Matt winked again and walked over to Billy in the opposing corner, making sure his gloves were secure as well as he whispered to his friend and rival, "How you feeling, Champ?"

"I'm fine," Billy lied, his voice cracking slightly. He felt like he was facing his own execution, so he should probably say his last words. "J-just so you know, Mattie... I...I'm sorry. About all of it..."

"I believe you," Matthew said bluntly, with just the slightest hint of remorse, but he gave his friend a playful smirk that quickly hid it. "But we're past the point of regrets, dude. Maybe we can figure things out after this is over, but right now..." he leaned in close, giving a harsh whisper, "...I hope she wipes the floor with you~"

Billy gulped, but said nothing. There was nothing more to say.

Matt stepped back and moved to the center of the ring, raising his arm high. "TOUCH GLOVES!"

Billy shuffled forward, meeting Carly halfway. Up close, the difference in height was obvious, and yet Carly's aura made her seem like the giant, even as the champ looked down at her. As their gloves tapped lightly, he couldn't deny the ache in his groin at her confidence. Her eagerness to destroy him. Carly leaned in, her breath tickling his skin as she whispered in his ear.

"Payback time, Billy boy, and it's been a long time coming. Get ready, because they're gonna have to carry you out on a stretcher~"

A shiver raced down Billy's spine at her whisper, his cock throbbing with painful excitement at the threat. He looked pale and nervous as he watched Carly strut back to her corner, her booty boulders giving a firm sway and wobble with every tantalizing step. Matt had to snap his fingers in front of Billy's face to get his attention so he could send him back to his corner.

Billy retreated to his position, his mind racing. He knew he had to get his head in the game or he was finished, but all he could think about was the rhythmic bounce of Carly's glutes and the terrifying promise in her voice. Of her delivering her killing blow she had been denied days ago. Of being a humiliated loser, knocked out at Carly's feet.

Across the ring, Carly settled into her stance, her eyes locked onto Billy with unwavering intensity. She wasn't just focused, she was hungry. Years of frustration and humiliation were about to be repaid, and the look of fear and desire on Billy's face couldn't be any sweeter~

Matt stepped between the two fighters, checking their stances one last time. He looked at Billy, then at Carly, and finally brought his arm up high.

"ROUND ONE!" Matt bellowed, dropping his hand sharply.

DING!
