“So that’s about everything.” Maki finished, as she showed the last of the school classrooms to her new junior.

 

The green haired girl watched as Nobara looked around with wide eyes, still only slightly masking her giddy excitement despite this being the fourth of the nearly identical classrooms they had seen that day.

 

Chuckling lightly, Maki looked down at the shorter girl with a raised eyebrow.

 

“Is it really that exciting? I mean, you had classrooms back in your hometown too, right?” Maki questioned as Nobara continued looking around.

 

“Huh?” Nobara huffed out as she looked up at her new senior. “Are you kidding? These are waaaaaay better than the ones we had back in the countryside! Hell, the bathrooms here are bigger than some of the classrooms I used to be in. Viva la Tokyo!”

 

Spreading her arms wide into the air, the 1st year shouted the end of her sentence for extra punctuation, listening happily as her voice echoed around the grounds of the quiet school.

 

Smirking once again, Maki placed a hand on Nobara’s shoulder before quickly beginning to pull her along the walkway, a soft gleam present in her eyes.

 

“Well then, Nobara-kun!” The girl started, using an overly flamboyant voice that sounded suspiciously similar to Gojo. “If you think that’s good, you won’t believe what we have next.”

 

“Eh? There’s still more?” The orange haired girl blinked in surprise as she continued to be pushed along the grounds of the school.

 

With the gleam in Maki’s eyes growing brighter, she continued ushering the confused girl along for nearly two minutes until they stopped in front of an old fashioned wooden building that was hidden just behind their school dorms.

 

“Ehhhh! No way….” Nobara gasped in shock, the slow realization of what the building they were standing in front of dawning on her as she stared at the old yet sturdy wooden structure. “M-…. Maki-san, i-is this a….”

 

“Yup! I figured you would like it if I saved the best for last.” The older girl said with a smug grin on her face. “Welcome to the Jujutsu High Natural Hotspring. There’s springs both indoors and outdoors, and they stay the perfect temperature year round. The students are in charge of cleaning and maintaining it, but….”

 

Leaning down until her mouth was nearly pressed against Nobara’s ear, Maki gave a quiet whisper.

 

“It’s open 24 hours a day, seven days a week. Free for us to use whenever we want.”

 

Backing up to gauge the new student’s reaction, Maki watched as Nobara just stood with her head down, hair covering her eyes and her entire body lightly shuddering.

 

Until,

 

“TOKYO BANZAI!”

 

With a thunderous shout that once again echoed across the campus, Nobara jumped happily before whipping over to Maki in an instant.

 

“When can we go in, Maki-san?!” The girl said excitedly as she grabbed onto the older student’s sleeve, eyes shining with excitement.

 

“Didn’t I just tell you? It’s open 24/7, and there’s a reason I saved this place for last. Let’s hop in now.” Maki replied, throwing her arm over Nobara’s shoulder with another grin.

 

“Besides….” Maki began as her grin turned a bit more lecherous, while she subtly moved her hand down further until she was gently groping Nobara’s boob, massaging it dexterously. “I think it’s about time we see what each other have hiding underneath here, don’t you?”

 

Freezing momentarily at the sudden fondling of her breast, Nobara quickly looked up towards Maki with a lewd smile matching Maki’s own.

 

“Oh man…. To be honest, Maki-san, you’re the first girl I’ve met other than my family that’s also a sorcerer. I’ve been dying to see what you’ve got underneath your “Curtain” since we first met.” As Nobara finished her sentence, Maki felt her shift slightly before a small hand soon began massaging her ass. “Well, how about we head into the changing room together?”

 

Licking her lips at the sight of her junior’s excitement, Maki released Nobara from her gentle hold after one last squeeze before walking into the building, beckoning the new student after her with a finger.

 

“Naw, we wouldn’t want to ruin the surprise now would we? You take the one on the right, and we’ll meet inside once we’re properly undressed for the occasion.” Maki said as she disappeared into the changing room on the left.

 

With her full lips stretched across her face in a bright smile, Nobara quickly jogged into the other changing room, already half way done unbuttoning her blazer before she had even cleared the doorway.

Unbuttoning her top as she stood in front of the clothing hamper, Maki felt a warm pool begin to form in her belly as she looked into the mirror at her figure.

 

Even while fully clothed it was clear to see that the girl had a great body, with large perky breasts visible even through the layers of her top, and a well rounded ass that was clearly outlined though her skirt, however, that was only what a normal person would think.

 

Those familiar with the Curse World, however, knew otherwise.

 

As Maki finally removed her top layer, she watched with joy as her boobs began ballooning out underneath her button up shirt.

 

Though that side would be completely out of the ordinary to witness for any normal human, for those at Jujutsu High it was just a normal occurrence.

 

The one piece of common knowledge most widely known among even the most beginner Jujutsu sorcerers was that the source of cursed energy was negative emotions.

 

What not many knew, however, was what exactly qualified as a “negative” emotion.

 

There were the obvious ones, such as anger, fear, hatred, and envy. But there were also some that were less apparent, such as hesitancy, confusion, or even emotions linked to basic human needs like hunger.

 

However, despite such negative emotions being needed for cursed energy to be produced, it wasn’t like all Jujutsu sorcerers were angry or hungry all the time. But that was because most curse users drew the majority of their power from a different negative emotion.

 

Lust.

 

Sexual hunger, desire, libido, lechery, and the wealth of fetishes humans in the world had all been found hundreds of years ago to be classified as “negative emotions” when it came to the production of cursed energy. Then, after decades of study, it was discovered that not only were sexual emotions found to be one of the primary producers of cursed energy in most sorcerers, it was also one of the most potent.

 

In fact, it was actually too potent, and with each new generation of sorcerers being found to have greater sexual appetites than the last, their lustful emotions soon began producing more cursed energy than they had the capacity to store.

 

So, with nowhere to go, all that cursed energy returned to its source. Specifically, it returned to the sexual zones of the body, causing the energy to settle and enhance those parts of the body as it stored itself inside.

 

For male curse users this meant that not only did their already high libido’s shoot through the roof, but that as more and more cursed energy amassed inside their genitals, the organs expanded in size greatly over time.

 

Females on the other hand, similarly found their libido’s skyrocketing, but instead of their genitals, they found that the erogenous zones of the body saw the majority of the growth from their excess cursed energy.

 

Over the generations, their tits and asses continued growing in size with their bodies becoming curvier and curvier the more cursed energy they possessed, to the point where curse users began to view the size of theirs endowments as a status symbol, with bigger boobs and asses on women and the larger cocks on men commonly thought of to be linked to a higher potential as a sorcerer. Whether that idea was true or not was often debated, but nevertheless the stereotype remained deeply rooted in Jujutsu society to this day.

 

But what about someone with almost no cursed energy like Maki?

 

Smiling at herself in the mirror again, Maki finally released the last button on her dress shirt, watching with familiar excitement as her boobs instantly bounced outwards while jiggling against her chest. Her already impressive set of tits began immediately growing larger even faster than before as they soon surpassed the size of her head before coming to a complete stop. Groaning in pleasure, Maki reached forward and began massaging her heavy tits while gently fondling her large nipples.

 

“Ah, that feels much better….” The green haired girl called out with a sigh, before releasing her boobs reluctantly.

 

Dropping her hands down to her side, Maki began unzipping her skirt as she walked towards the entrance to the hotspring. She had kept her cute junior waiting long enough.

 

As she walked, the tall girl groaned in excitement as she continued unzipping her skirt, feeling a burning pleasure as she felt her ass begin to expand outwards, growing in size.

 

Due to their enlarged endowments, cursed users eventually grew to the point that it became difficult for them to move in combat situations thanks to their size. However, after years of study a solution eventually was devised from an unlikely place; Lord Tengen.

 

Tengen’s barrier were primarily used to hide and compress the areas that curse activity was taking place in, which allowed sorcerer’s to protect the outside world from dangerous spiritual activity.

 

But eventually someone had the idea to use a miniaturized version of Tengen’s barrier on their own body. As a result of this, select areas on a person could be shrunken thanks to the barriers’ effects, resulting in much more freedom of movement as well as less attention from non-sorcerers in everyday life.

 

While it wasn’t at all uncomfortable having your tits or ass shrunken by Tengen-sama’s barrier, it did leave you feeling unnatural throughout the day. This led to almost all sorcerers preferring to let their natural bodies out when relaxing, despite it generally being harder to move around in.

 

Maki, of course, was of a similar mind as she dropped her skirt to the ground, groaning in pleasure as she felt her thighs and ass continue to thicken and expand.

 

Finally, with Maki left in only her leggings and a lone heart shaped pasty over her pussy, the second year finally entered the open air spring, being greeted by a thick veil of steam.

 

“Maki-san, is that you?”

 

“Yeah, I’m coming in now.” Maki called, unable to see her junior through the thick steam.

 

Heading towards where she heard the first year call out from, closer to the center of the pool, Maki headed towards the sound. Dipping herself into the water, the girl began wading forward through the thinning steam.

 

As she drew closer, the natural veil started to clear in front of her and she caught a glimpse of Nobara’s auburn hair.

 

“So how are you enjoying the water so far, Nobara?” Maki called out as she saw a clearer view of the girl’s face. “Pretty nice, huh?”

 

As the steam drifted lower past Nobara’s collar, Maki’s eyes locked onto the other girl like a hawk. She wasn’t expecting too much from a first year, as she would’ve just recently awoken to her cursed energy, but despite that Maki knew that even a younger sorcerer like Nobara could be packing some serious curves.

 

Despite her lack of curse energy herself, Maki was confident that she was still well endowed even among other Jujutsu users. This was because of her heavenly restriction, which not only seemed to increase her physical abilities to far beyond normal, but also her physical traits as well.

 

“Oh yeah, this place is awesome! I’ve barely even taken a dip but I feel so relaxed…. This could start becoming a habit.”

 

“Heh, tell me about it. I already come in here almost every night.” Maki said with a grin, before she walked even closer to her junior, lightly waving her hands to remove more of the steam in-between them. “And now that I have another girl to talk with we can-”

 

Jiggle.

 

“Wow, Maki-san! Your pasties are so cute! You have to show me where you got them later! It’s been such a pain trying to find thongs that will fit me lately, and when I finally do get some I always grow out of it in a few months.”

 

Jiggle jiggle.

 

“You-…. wh-… how-….” Maki could stare slack jawed at the sight in front of her.

 

There stood Nobara in the center of the pool, but it was not the Nobara that she knew.

 

Staring down at the girl’s body was like looking at the embodiment of lust. Resting on her chest was a pair of tits that could be described as nothing other than massive, which each boob being almost twice the size of her own head, and each mountain of jiggling flesh was topped off with a massive pink areola that were so large you wouldn’t even be able to cover one with your hand.

 

But what was even more shocking was the size of the girl’s ass. Each cheek was so large that even from her position in front of Nobara, Maki could easily see the oversized buns coming out of the brunette’s hips, flowing nicely into some of the most dangerously thick thighs that the young Zenin had ever seen.

 

“Hmm? What’s up, Maki-san? You’re looking a little pale….” Nobara asked the older girl, as her smile quickly turned into a look of concern.

 

“Y-… Your boobs…. And your a-ass….” Maki stuttered out, eyes flickering dangerously between each organ.

 

“Huh? Oh yeah, sorry, I was a little too excited so I jumped in before my Curtain was fully released. I know they’re a little small now but just give it a few moments and they’ll be back to normal.~”

 

As if on cue, Nobara let out a slight moan, before her already giant breasts gave a slight jiggle before slowly beginning to expand forward.

 

“Wha- Bigger!?” Maki exclaimed in shock.

 

Nobara, however, seemed to either ignore or not notice the other woman’s exclamation as she continued on.

 

“But enough about me, Maki-san, you should release your Curtain technique already! I can’t wait to see how amazing a second year’s body is!” Nobara exclaimed with a slight bounce of excitement, causing her entire body to jiggle violently as her tits and ass continued to grow. “I bet you’ll knock me out of the park! Look, your ass is already starting to grow and your Curtain isn’t even off yet!”

 

Indeed, Maki’s ass had start to begin bulging outwards as the remains of Tengen’s Curtain started to fade away, but as for any growth that it had made, Nobara’s seemed to double down on it, as the girl’s already huge ass continued filling out, becoming more round and full by the second.

 

“But I….” Maki began, pausing as she swallowed a bundle of nervous saliva that had pooled in her throat. “I already removed my Curtain spell…. Before I left the changing room….”

 

Maki could only watch in fear as Nobara’s growth finally stopped. While the girl’s chest had been absolutely ludicrous before, it was something else entirely now, with her absurd breasts now covering her belly button thanks to their sheer size, and extending out enough that her nipples had disappeared from sight beneath Maki’s own underboob.

 

“….Huh?” Nobara raised an eyebrow in confusion as she gave her senior a puzzled look. “There’s no way, Maki-san, that would mean you’re actually that small….”

 

Her confusion visibly growing, Nobara began looking up and down between Maki’s boobs and ass.

 

Up.

 

Down.

 

Up.

 

Down.

 

Click.

 

With a sudden moment of realization, Nobara finally looked up into Maki’s eyes once again. Now, however, the girl’s previously excited smile had been replaced with a relaxed smirk accented by half lidded eyes as she stared up at the taller woman in front of her.

 

Placing a hand on her hip, causing her now monstrous ass to jiggle enticingly from the minor movement, Nobara walked a little closer to the girl in front of her.

 

“Well…. I guess some people are just a little more well endowed than others…. It’s no big deal, after all, who really cares if someone’s bigger in one place or another, right, Maki?”

 

As Nobara continued walking forward, her giant tits soon began pressing pleasantly into the Zenin girl’s stomach, causing an indescribably pleasant feeling as they squished around the shape of Maki’s toned abs and the underside of her breasts.

 

But instead of enjoying the pleasure, Maki could only focus on the sinking feeling beginning to bloom in her stomach as she stared at the ridiculously curvy girl below her.

 

The sinking feeling that the balance of power between the two had suddenly shifted.
