Being Stepped On During Splits Is Common Sense♡
Flexibility is the very genesis of proper posture, and a flawless posture is the most intuitive display of innate superiority. Naturally, concluding a stretch with leg splits was only to be expected. Just as naturally, attempting to force a split on one's own makes it nearly impossible to adequately expand one's range of motion. Thus, relying on a partner's body weight was simply common sense.
And yet, of all the wretched souls on earth, my partner just had to be that bastard again…
I yearned to slash that smirking, sun-tanned blonde delinquent's face to ribbons. But completely indifferent to the murder brewing in my heart, the teacher's whistle let out a sharp shrill.
Tweeeet—!
With that, the instructor dropped flat to the floor to demonstrate. The first rotation of students tasked with splitting—myself included—dutifully followed suit. Breasts pressed flush against the polished wood, we spread our legs wide open like frogs. With our preparations complete, the teacher blew the whistle once more.
Pweeeeeeep—!
“Ah, ahh…”
“Ahn, nnnh…”
“Oww, hyuuung…”
“Mmh, nnff…”
Indecent, stifled whimpers echoed from every corner of the gymnasium, and I was certainly no exception.
“Haaahnn…♥”
A sharp, electric jolt shot straight through my inner thighs. The harder that wretched worm stepped down on me, the more agonizingly electric the sensation became, as if my thigh muscles were being ripped apart strand by strand. Speaking to him was vile and degrading, but this was one grievance I could not swallow.
“Hey. Step on my lower back, not my ass.”
“Ah, sorry, my bad! It's just, your butt curves up so high that it's kind of impossible to keep my balance on your waist.”
For once, the maggot wiped the grin off his face, apologizing with a remarkably earnest and contrite expression.
Urgh…
My knee-jerk reaction was to dismiss it as sheer sophistry, but the more I turned it over in my mind… the more reasonable it sounded. Indeed, balancing purely on my narrow waist might pose a genuine mechanical challenge. Even so, stepping directly on my rear was bound to—
“Hngh…!”
Inevitably, my worst fears materialized. My paper-thin, skin-tight gym shorts were paired with special functional panties engineered solely to conceal the contour of my mound. While they offered supreme breathability during physical exertion, any external contact yielded a sensation practically indistinguishable from bare skin against bare skin. Come to think of it… shouldn't we have changed into different clothes before doing this? No, wait—before that…
Would anyone ever step on a girl in a posture like this just to improve flexibility? And by a member of the opposite sex, no less?! Something about this is completely insa—eeeeeek?!
“Hey! Stop, stop pressing down, it hurts!”
“Ah, sorry… but teacher said to do it this way…”
There was that guileless, dead-serious look again. Sigh. It couldn't be helped. No matter how thoroughly bound for a pathetic gutter-life this worm was, embracing a peer who displayed such sincere dedication to school activities was the solemn duty of the student representative and the first-year class topper. Meticulously composing my facial expression, I gritted my teeth against the scorching pain invading my thighs.
By the way… what was I just thinking about? No, surely not. I have never once forgotten a single thought in my entire life. A brilliant mind like mine would never suffer the absent-minded lapses of an imbecile. Absolutely not.
Regardless, owing to the specialized athletic undergarments and academy gym uniforms, my crotch felt excessively sensitive. Well, this was merely the academy's profound wisdom at work—teaching us to experience life by bearing comfort and discomfort in equal measure. I had no intention of complaining. My most private, delicate place was being ground into the hardwood floor, growing raw and hypersensitive, but overcoming such tribulations was the noble destiny of pillars of society like me. I had to accept it.
Throughout my stoic endurance, that filthy insect kept grinding his foot down into my buttocks. Squeeeeze♥. Fortunately, maintaining a steady, continuous pressure kept the stimulation at a threshold my groin could somewhat tolerate. However, the stretching routine still had another phase in store.
After about thirty seconds of bearing his weight on my rear, the whistle cut through the air once more. Tweeeet—! It signaled the end of the first posture, and simultaneously heralded the beginning of the next.
“Now, bounce and press in rhythm like this, everyone~ Squish, squish! Keep pressing rhythmically for three minutes before switching!”
Concurrently finishing her instructions, the two teachers demonstrated the movement. The foot of the instructor pressing down pumped up and down atop the stretching teacher's back like a piston. The stretching teacher's waist dipped and rose in tandem, rocking down, up, down, and up. Each time, momentum drove her hips deeper and deeper, until her pelvis seemed virtually glued to the floor.
“Ah, ahhng…”
Since the teacher only needed to demonstrate, she stopped after a brief ten seconds. But we were expected to endure this for a staggering three minutes. Wasn't that far too long? The complaint rose in my throat, but reframing it not as mere stretching, but as rigorous mental discipline made the duration feel entirely justifiable. In any case, the end of the demonstration signaled the commencement of our personal hell.
Right on cue, the whistle blew.
I clamped my jaw shut, but any semblance of composure was violently stolen away by that bastard lowlife ruthlessly stomping down on my backside. Squish♥ bounce♥ press♥.
“Hyaah! Ah! Aah! Hngh, aahn!♥”

The thin uniform caused violent, merciless friction between my groin and the polished boards. The resulting sensory assault was by no means a disaster visited upon me alone; shameless moans erupted simultaneously across the entire hall.
“Haa, haahn, ahh…”
“Nnff, h-haa, hah!”
“Hyoooohk!!♥”
Even so, I held out remarkably well compared to the others. Yet as the seconds dragged on, the fundamental disparity between male and female physiology made itself painfully apparent. Maintaining one's balance while bouncing atop someone is easier said than done; keeping it up for three uninterrupted minutes is bound to exhaust the person pressing down. True to form, the hips of the other girls were no longer vibrating with their initial fury.
Mine, however… were bouncing far faster and far harder than when we had first begun.
“Hnngh… ha… h-nnff…! Hyaat!♥”
Everyone knew the reason. I knew it, he knew it, we all knew it. Because my partner was the sole male in the room. Unworthy mongrel though he was, he possessed an athletic build and stamina that did his sun-kissed skin justice. Like a runaway locomotive charging without a second's hesitation, the punk relentlessly hammered down into my ass with unwavering rhythm and immense force.
Yet if I endured this, it would serve as public, undeniable proof that my mental fortitude eclipsed that of every other student present. I dug my fingernails desperately into the smooth wooden floorboards, clawing for purchase. Given the targeted anatomy, a certain sexual stimulation was unavoidable, but the searing throb in my inner thighs kept my mind from succumbing entirely to wanton thoughts. That, at least, was a blessing. If I were to be driven to climax simply from being stepped on by an inferior male…
Haah…
The sheer agony was making me hallucinate absurdities. I shook my head violently and opened my eyes wide just as the countdown began.
“Five, four, three, two, one! That's it, switch!”
Finally! It was finally over! With the ordeal concluded, I could at last pull my splayed thighs together. And yet…
What? Something inconceivable occurred.
“Hey. Move your foot.”
As if struck deaf, the insect refused to lift his foot off me. Worse still, his expression was the absolute pinnacle of brazen audacity—he stared at me with an innocent look, as though he couldn't comprehend a word I had said.
“I said take your foot off me right now!”
Only when I raised my voice did an enlightened "Ah~" slip from his lips before he spoke.
“Um, excuse me, have you only ever attended all-girls schools until now?”
I couldn't fathom the intent behind the inquiry, but it wasn't overtly hostile. In that case, answering candidly was the proper conduct of a role model.
“I have. What does that have to do with anything?”
Slap! The delinquent clapped a hand to his knee in sudden realization.
“Aha! That's why you didn't know! A man's physical strength is simply too much to be pressed down by a woman's weight. Furthermore, it's a scientifically proven fact that men possess far less natural flexibility than women. For those reasons, when a boy and a girl stretch together, only the girl does the splits.”
Is… that so?
Hmm…?
A dull, numbing tingle washed through my brain. As I hesitated in contemplation, he pressed forward, his voice brimming with barely suppressed amusement.
“Right? Isn't that right? Pfft, hehehe.”
Well… yes… I suppose… That does sound remarkably logical, doesn't it…? Wait, or is it…?
“Right? Hey, am I right? Everyone, isn't that how it works~?”
He turned outward, canvassing the surrounding students. He sounded utterly confident, and the answers echoing back only served to validate his claims.
“Yeah, obviously.”
“Well, if she's never been to a co-ed school, she might not know.”
“Still, she worked really hard, maybe give her a break for the second turn…?”
Among them were a few gentle-hearted classmates who showed concern. But this was my choice. I had to be remembered as someone who was fully aware of the rules and willingly sacrificed herself to aid a peer. Backing out now would run counter to my pride and character.
“I don't mind at all,” I stated nonchalantly. “If anything, I'm glad to have learned something new.”
At my composed reply, the delinquent hovering over me began choking on his own snickers. Hmph. While his vulgar nature remained as repulsive as ever, it was also true that as an athlete, he had shown genuine remorse and seriousness while pressing down on my buttocks. Overlooking a minor blunder—or a little harmless mockery—was simply part of the magnanimity expected of a student representative.
“Stop laughing and get ready again.”
Refraining from harsh rebukes and merely demanding readiness naturally silenced the dog's chuckles. This was true elegance. I personally guided his foot, shifting it from my rear toward my lower back.
“Try practicing your balance this time. That way, you won't embarrass yourself in front of whoever your partner is next session.”
“Pff-pfft! Khh… ghck… Thanks…”
Perhaps I had misjudged the boy slightly. It seemed he was merely prone to laughter. While he couldn't suppress his giggles, the remorseful look on his face appeared genuine enough.
Yet even amidst this amicable atmosphere, the whistle blew without mercy.
Pweeeeeeep—!
“Hnghk… h-aah, hah, hah…”
Once again, lewd cries erupted across the room. Yet as they say, humanity is an adaptable species. While the rest of the undisciplined girls openly wailed in arousal, I demonstrated miraculous endurance, weathering the storm in absolute silence. Ultimately, I weathered the full three minutes of rhythmic pounding flawlessly.
My goal of securing an impeccable reputation at the entrance ceremony was a roaring success. Though the day had begun with an ominous portent and a lingering sense of unpleasantness, I had achieved every single objective I set out to accomplish. One glance at the list of saved contacts from Baekgyeol Higher Education Girls' Academy on my smartphone confirmed it. Out of the 124 first-year students, forty-five numbers were neatly stored in my phone. In a single day, forty-five peers had stepped forward expressing their desire to become close with me.
“Fufu. I'm so glad I came here.”
Though starting the morning with a nightmare about tumbling down a cliff had made for an exhausting day, concluding it with the highest possible outcome meant I had somewhat overcome the jinx. The only truly disgusting detail was that nestled among the contacts of the friends who had eagerly asked for my number was the contact information of that mongrel delinquent.
It was distasteful, but I had made friends to walk home with, and it was a monumental day celebrated with after-school fun. I decided to bury such minor unpleasantries. After all, it wasn't as if our paths would cross often in the future.
Thus, an eventful day drew to a close. Today, as always, I was noble, superior, and supremely elegant. Finding that nobility amidst such trials made the satisfaction all the sweeter. I genuinely prayed that tomorrow, and the day after that, would unfold just like this one.
Completely blind to the horrifying curse I had just wished upon myself.
