[Instant Hyper Preg]

In this world, there are many martial arts. And most of them have already been pushed to their limits, courtesy of what humans are able to do. But some still have potential. Some have secrets that are still left to be unlocked. Some still had to be shown to the world.

That was the spiel that young Ryu had gotten from his Grandfather, before he was forcibly taught his secret art. 'Botehara-Ken'. Of course he never actually taught him what it was supposed to do, just what he had to do to use it. And when he started falling down on his luck and didn't have many prospects for his future, his Grandfather did him a favor. Signing him up for a prestiged tournament, where he would be able to prove his skill against other arts.

Which was how Ryu had ended up staring down a girl that was a head shorter than him. He wasn't exactly a tall youth either, it's just that the girl who stood opposite of him was shorter because a lot of her weight was concentrated down below. Focused on her thighs, which made it hard to really look at her and her seemingly shut eyes, or the cute buns that formed her hair. Especially hard to focus on those upper body details when that very same set of thighs were completely uncovered, with only a painfully tight looking leotard serving as the girl's choice of combat attire. It really made her look like a dumpling that happened to wear a dress...

"Where are you looking, Ryu-han?" The girl asked, as she carefully assumed her stance with a soft smile on her lips. "This is a tournament, if you leave yourself open for even a moment, I will seize victory." She made her intentions clear, while beckoning the boy to strike first. Not because she thought of him as weak, but she wanted to show him that she could counter any move that he made.

"I-" The young boy paused, before shaking his head. Compared to his opponent, he was barely even ready. He had slapped on a gi to look like he was ready for a fight, but he hadn't properly tied his belt or anything. Not to mention it was a hand-me-down too, he wasn't even really fit for it. Maybe he should've trained so he could fit his grandpa's digs properly. "W-What's your name anyway, they didn't tell me! I don't wanna fight somebody I don't know!"

The shorter girl chuckled, before briefly bowing her head while still in her combat stance. "Bao. Get ready, Ryu-han, if you won't make the first move, then I will!" After briefly introducing herself, Bao took a single step... And came crashing forward, using the momentum of her step to swing her leg over her head, bringing her foot straight down towards the boy!

Ryu's eyes widened as he quickly dodged out of the way, sweat running down his head as he looked at the cracks in the floor below. Those thighs weren't just for show, she had a lot of strength packed into them! How was this crummy martial art supposed to compete against that!?

"Faster than you look, impressive, Ryu-han!" Bao giggled, her eyes briefly opening as they sharpened into a glare. "But if you do not attack, you'll fall. Just like everyone that didn't take me seriously just because I've got hips like a dumpling!" She shouted, as she didn't let up the offense. Even if her leg was partly stuck in the floor, she could still keep kicking like a wheel, her foot flying straight towards the young boy!

He couldn't dodge for long if this was what she could do. The only way he had to beat her was to actually use that technique. As far as he could recall, he had to split his fingers, and then... Yeah, he could probably land that hit. He just had to focus, especially when that foot was rapidly approaching his face!

"Bohehara-Ken Ougi!" Ryu shouted as he split his pointer and middle fingers apart, forming a V, before jamming them straight towards the lower part of Bao's stomach. He even let out a shout to amp himself up, landing the blow just as the kick was delivered straight onto his head, causing his eyes to roll into the back of his head from the sheer pain running through him.

Though once the pain went away, all he could see was Bao stuck on the floor. Not because he had caused her any pain, but rather because it seemed like her stomach was visibly writhing. "H-hey! Are you okay, Bao?" His natural instinct was to worry about this girl, even though she had practically given him a concussion after that blow.

She didn't answer him with much more than a desperate and overly satisfied moan, as her midsection very suddenly burst outward. Her tummy grew several sizes in a matter of seconds, making her look like she had been pregnant with twins, triplets, hextuplets... And she was still growing. Only when she looked like she was overdue with well over a dozen kiddos did the growth stop, with Bao trembling and gasping as her body struggled to process what had happened, especially as her matching enormous breasts, which were now bigger than her head, drooled out so much milk that she was lying in a pool of her own nourishing white liquid.

"T-That... Ryu, that was..." Bao gasped and panted, hands resting on her belly as her eyes opened fully to reveal hearts in place of her irises. "I-I've heard of this martial art, b-but... T-To experience it first hand... A-Ah..." The painfully stretched fabric dug into her pussy, revealing how much she was truly leaking at that moment. "It feels... It feels so good to be this full... Ehehe... I always wanted to continue my family tree after my Mother decided to leave us, but this is more than I could've ever hoped for..."

Ryu stared at his now extremely gravid opponent in shock, all while looking down at his hand. He wasn't sure how he was going to handle what he had just done, much less accept the sheer power in his fingertips...

He... He had to be careful, otherwise the other opponents could end up just like her... E-Even if Bao was really cute like this...

---

"Hey, hey! What's the matter, shrimp?! You did that to lil' Bao, and you can't handle somebody bigger? C'mon, give me some pleasure!"

Somehow, Ryu went from the proverbial frying pan and straight into the fire, as he narrowly dodged out of the way of a much larger woman's muscled arm. He had barely even introduced himself before she went to town, launching attack after attack and barely giving him any chance to breathe. It was actually more than a little overwhelming!

"C'mon! You can't just keep dodging, that's no fun at all!" The much larger woman shouted as she tugged her arm out of the wall that she had smashed it through, pulling out a brick in the process and crushing it to show just how powerful she was. "Martial Artists like you are all bark and no bite, none of you can handle raw strength!"

"Give me your name and I'll stop dodging!" Ryu shouted, gasping as the sweat ran down the side of his head. It didn't help that he was extra exhausted after he helped Bao get to somewhere safe before he went to his next match. His arms were aching and begging for him to stop. But he didn't want to give up. Not now. Not when he had somebody else riding on his shoulders. He needed to win, for the sake of the girl he had managed to knock up with nothing but his fingers.

The oversized woman, who was clad in little more than a tiger-patterned tube-top and matching thong, grinned as she punched her fist into her palm and let her muscles bulge out ever slightly. She wasn't obnoxiously muscular, but compared to the tender plump figure that he had just fought against, she was an entirely different beast. Especially since she towered over him by several heads, her long beastly blonde hair stretching all the way down to her hips. "Taiga! Now come on, brat! Fight me and show me that technique that knocked out the dumpling!" Taiga shouts as she dashes forward, every step causing the ground underneath to shake as her muscles start to bulge out against her arm, showing the power of her body concentrating in that limb.

Ryu did as he had promised. Meeting Taiga's strength head on. Literally, as he slammed his head straight against her fist by running towards her and slamming into it, causing him to suffer much less damage than if she had managed to actually land her punch. And at the same time, stunning her for that brief moment that he needed. Sure, his face had seen better days, and he definitely needed to get something adjusted after everything was said and done, but knocking her off balance was important.

He could see her exposed stomach. And though it was covered in abs, that wasn't the reason why he felt like he needed the extra moment to breathe. No, it was because he needed a powerful blow to subdue her. If a blow like the one he had inflicted on Bao was able to do so much to her, then he needed a stronger one to deal with a stronger opponent.

"Botehara-Ken Ougi!" The boy cried out as he concentrated both sets of pointers and middle fingers, using them both for the pincer-like strike as he dashed towards the staggering beast!

Taiga grit her teeth as she was forced back. "You little runt, you're a lot craftier than I gave you credit for-" She tried to taunt him for what he had done, only for her eyes to widen as she felt the pressure put upon her body once he slammed his fingertips straight into her stomach. The feeling pierced straight through her and the pressure spread across her form, causing her to collapse onto her knees as a massive moan left her lips...

Ryu panted, collapsing onto his own knees as the adrenaline left his body. He was in the perfect position to watch as every single muscle across the entirety of the tan woman's body deflated all at once, leaving her a lot smoother than she was before. Not only that, but she was a whole lot cuter too now that all the scary strength had disappeared.

"T-TOO MUCH!" Taiga shouted as she experienced growth that was just as extreme as Bao's. Only she started at the dozen mark, with her stomach growing little by little as another kid was added to the brood forming inside her. One by one by one, each of them making her moan more and more as her stomach eventually started to brush out against the boy that had delivered that blow to her...

Ryu panted as he slowly got back up, blushing brightly as his cheeks brushed against his opponent's enormously gravid belly. Instead of asking if she was okay, he did the smart thing and just walked around the stomach, to hopefully see a less stressed expression...

Only for Taiga to grab him as he got into her range, her expression just as heart-filled as Bao's. "Y-You're not going anywhere... W-We're... We're not done!" She said, the hearts trembling as she tried to overwhelm the new feelings inside her. But she couldn't, especially not as plenty of milk started to splurt forth from her tits. "Y-You have to take responsibility for what you've done, a-and make sure I'm perfect for you! T-There's no better hubby than you, Ryu..!"

Ryu felt the sweat pouring down his face as he was yanked into a hug, and forcibly introduced to the remaining strength within her body... And how much of that love that had flowed through her was meant just for him...

He just hoped that he'd be ready for his next fight in time...

"To think there was still a Botehara-Ken user left in this world."

Though Ryu had managed to recover, currently covered in so many cute golden kisses thanks to how much Taiga had showered him in love, what he heard from his next opponent caused him to feel a chill stronger than anything else. "You... You know of it..?" He asked, slowly entering a stance. This opponent was not one to take lightly.

His opponent was a gentle looking girl, who wore a kimono as her long black hair reached all the way down to her rather impressive looking hips that were brushing out against it. "My great great Grandmother had been a victim of its influence. But it was because of her loss that my bloodline developed a technique to leave it completely inert. As you have managed to inherit it, despite the best efforts of my Grandmother... I'm afraid that I'll have to use that very same technique on you, Ryu-kun."

She took a single step forward... And then she vanished before his very eyes. Before he had a chance to find her again, he felt a single touch on his chest, and a shock pouring through, All while she became visible once more, and he could see into her somber yet determined blue eyes...

"My name is Mamori. Fall before the power of Kyozetsu-Ken, Ryu-kun." Mamori said, as she gently stepped back. With a single finger, she had been able to defeat him just like he had been able to defeat all the others.

As much as he wanted to get up, it was like a spark had disappeared from his heart. The... The affection he felt for those two girls, the affection that he felt for anybody in his whole life... It seemed to vanish right then and there. "W-What... What did you do, M-Mamori..?" The boy muttered, his eyes dimming as he looked up at her while falling right onto his knees as all the strength in his body faded alongside his affection...

"Kyozetsu-Ken rejects all affection. Without affection, your Botehara-Ken will never activate again. You will never think of using it against anybody, much less think of anything beyond just existing. This is necessary to protect the world from that impregnating fist." Mamori explained, gently closing her eyes. "Even if you were to have caught me out before I delivered the fatal blow, you wouldn't have been able to hit me. I pursue strengths beyond just stopping you and that technique. To that end, I've discarded any chance of my bloodline continuing. Just so I can become stronger."

Ryu listened, but it all went in one ear and out the other. She wanted to be stronger, and she had managed to disable him with little more than a poke. He understood that. But why did she look so sad while she did it..? It didn't feel right. The sad look in her eyes was causing the spark inside his heart to slowly return, as his body trembled and his fist tensed...

"Live a long and prosperous life with the ones you still have by your side, Ryu-kun. You'll need them if you want to counteract Kyozetsu-Ken-"

"I don't need them like that..! Just like you don't need to put up that front..!"

Mamori's eyes widened as the color in Ryu's eyes returned, and a flame started to burn within. He hadn't lost his passion. Far from it. It was supercharged if anything. Had she made a mistake..!?

"Stand down, Ryu-kun! That fist should be buried in history, so nobody can misuse it!" The elegant black-haired girl cried out as she started to vanish, ready to evade his blow by being too fast for him to catch her...

Only for her eyes to widen as he slammed his fist straight into her weak spot, his eyes flaring brighter and brighter. "I don't want to misuse it! SO STOP ACTING LIKE YOU HAVE TO BE THE ONLY ONE THAT HAS TO BEAR THAT RESPONSIBILITY, MAMORI!" The boy shouted, the sadness that he had seen inside the girl's eyes setting his soul ablaze as one punch turned into two, then four, and the punches just kept on doubling again and again, even if they didn't actually do damage!

Every punch added a little bit more to the stacking gravidity, with Mamori's mind doing its best to hold on. But it couldn't. Because she understood what he was trying to do. He wasn't like the man that had tied their destinies together. He was a boy who actually understood the gravity of what that fist did...

"BOTEHARA-KEN OUGI - AI!" With one final pair of punches to the composed girl's belly, the explosive growth that followed smashed him right in the face. And yet he didn't back down. Not even as it tried to push him further and further back. He just met the growth head on, standing his ground...

By the time that her belly started to brush up against the ceiling, he finally lost ground and got pushed out to the edge of her growth, giving him a view of what his love-fueled fist was able to do. All while his body forced him to collapse, clearly not satisfied with how badly he had overexerted himself in such a short time.

Though he could still hear and see what had happened to Mamori. Instead of treating him with disdain and hate for what he had done, she was giggling like a girl who had been set free, drawing a soft heart on the surface of her belly...

"To be the Mommy of Ryu-kun's children... Nothing'd make me happier..." Mamori sighed, the hearts in her eyes more genuine than ever. "Taiga-chan and Bao-tan as well... But you better prove that you were telling the truth, Ryu-kun. I don't want our bloodlines to feud again..."

Though he now had three loving girlfriends that were obnoxiously pregnant thanks to the power of his grandfather's secret martial art, he didn't seem too bothered. No, he would do exactly as he had told Mamori, and make sure to bear the responsibility of knowing this technique.

Ryu just smiled a bit as he came to terms with all of this... right before he passed out, satisfied with a smile on his face.
