A Promising Rival Emerges in the Female Sumo Club After Common Sense Alteration - 2
This world's common sense check.
1. Satisfying you and obeying your commands is the top priority.
2. No matter what words or actions you take, others hold no aversion toward them.
3. Your opinion is the truth, and no one holds any doubt about it.
I immediately pulled my smartphone out of my bag.
The man's hand was still gripping my breast.
His right hand fondled mine while his left hand fondled Mizuki's.
The situation felt so natural, yet for some reason I had to swallow the nausea rising in my throat as I made the call.
When the ringing stopped, that familiar bright and warm voice came through.
"...Hello? Oh, do you have a minute? Yeah... it's me. I already ate."
It would be polite not to beat around the bush.
"Sorry for calling out of the blue, but I decided to join a club called the Female Sumo Club. Ah, yeah... it's a bit unusual? Anyway, it looks like they don't accept girls who already have boyfriends."
"So let's break up."
Silence stretched on the other end before a confused, stuttering voice came through.
"Huh? Why would I joke about something like this? I'm getting my breasts evaluated by the Club President right now because I want to join."
Since it was such a bizarre club, he probably wouldn't believe me, so I switched to a video call and showed him the hand tightly squeezing my breast over my clothes.
The man's thumb slowly rubbed across my nipple.
The ticklish sensation transmitted through the bra material made goosebumps rise all over my body.
The sounds coming through the phone grew more intense.
It was a voice I could barely stand to hear.
I thought I had explained it properly, but he seemed completely shocked.
Strange. Was what I said really that hard to understand?
My voice trembled because of his hand, but that couldn't be helped.
He kept rubbing my nipple, after all.
Stimulated while already stiff, an urgent, unbearable sensation surged up from my lower abdomen.
"What... why are you, haah! getting so angry? There's nothing I can do about it. I really want to try this. Anyway, that's how it is, so from now on... hngh! Let's just be friends again. I'm busy right now, so I'm hanging up."
Getting angry over something so trivial, even though he always said he loved me.
Did he think being my boyfriend gave him the right to interfere with my club choice?
Good thing I broke up with him.
Yeah.
"Did you wait long? I just broke up. No more problems now, right?"
The man smiled faintly in satisfaction and removed both hands.
"Good. I'll welcome both of you."
Where his warmth and pressure had been on my chest, an oddly chilly air now lingered.
My slightly flushed nipples trembled inside my bra, still remembering the sensation.
"Welcome~!"
"Please take care of us~!"
The seniors in fundoshi standing around us clapped.
The lively applause echoed through the club recruitment area.
Ah, these people are my seniors now.
It didn't feel unpleasant.
When I glanced to the side, Mizuki was shyly scratching her head as well.
But her eyes were already sparkling, anticipating the fun times ahead.
"If you two have time, would you like to start activities right away today? Do you have any other plans?"
"Ah, sorry. I have a part-time job later today..."
"I have a lecture~"
"What? For a female, sumo is more important than that stuff. Did you join with that level of resolve?"
...He was right.
My thoughts shifted on their own.
Part-time job... female... is sumo more important?
Of course.
I'm a member of the Female Sumo Club now.
Once you're in, you can't half-ass it.
"Then I'll start today."
The man nodded in satisfaction and stood up.
"Alright, then. From today, real training begins. Since it's your first day, we'll keep it light, so don't worry. Could you bring two fundoshi over here~"
"Yes~! Just a moment!"
The seniors who had been promoting the club nearby approached with bright smiles at the Club President's words.
They carried two pieces of pure white cloth, just like the ones they were wearing.
"Here you go~! Try them on now, and let us know if the size doesn't fit?"
I looked around.
There was no space with even a makeshift partition.
The only option was to change clothes while leaning against the wall.
But... changing clothes? Right in front of the male Club President?
Mizuki and I looked at each other.
We hesitated for a moment, but our thoughts quickly settled.
Right, of course we should.
We couldn't show any timidity on the very first day.
As sumo wrestlers, exposing our bodies was only natural.
We accepted the fundoshi and stared at them for a moment.
They were much heavier and softer than expected.
They looked like nothing more than long strips of cloth.
How were we supposed to put them on...?
"Um... excuse me..."
Just as Mizuki, thinking the same thing, was about to speak, the seniors stepped in first.
"You don't know how to wear it since it's your first time, right? It's okay~ I was the same. We'll help you change, so take your clothes off first!"
...Eh?
"Hurry, hurry~! No need to be embarrassed!"
With those words, one senior reached for the hem of my hoodie.
The fabric rolled up following her hand, and my navel shyly appeared on my tanned skin.
"Aah!"
"Now raise your arms? Arms up~"
At the gentle tone, my arms reflexively went up.
The hoodie slipped over my head, tousling my hair as it came off.
Along with the feeling of my body becoming lighter, my upper body was completely exposed.
The spring breeze felt even more vivid now.
Only my black sports bra remained, barely covering my breasts.
It was slightly damp with sweat, making the shape of my chest stand out clearly.
"I'll be rude with this side too~!"
Immediately, another senior from behind slid down the dolphin pants I usually wore comfortably.
My buttocks flinched as they met the cool air.
"Uwah...!"
Beside me, Mizuki was going through the same situation.
The pink dress she had been wearing had already disappeared, leaving only red lace underwear visible against her pale skin.
The seniors stripped us naturally, as if dressing dolls.
The man leaned against the wall with his arms crossed in a very relaxed posture.
His gaze never left us for a moment.
It's fine.
This is normal, Choi Yuna.
You're not a taekwondo athlete anymore.
You're a female sumo wrestler now.
I repeated it to myself several times, but my heart raced on its own and sweat beaded on my fingertips.
"Take off your underwear yourselves. You can't rely on your seniors for everything."
The man said this while tilting his chin.
At his words, the seniors nodded and stepped back.
My eyes, with nowhere to go, met Mizuki's.
"...!"
We looked at each other and smiled awkwardly.
Then, as if on cue, we both reached for our bras at the same time.
With a soft rustle, the bras slipped off our shoulders.
Along with the sensation of weight settling, two contrasting pairs of breasts spilled out and bounced at once.
The cold air touched our nipples, making them tremble.
Amid the crowd of breasts, two pairs of large new ones floated in the air.
I had always been confident in my size no matter where I went, but in this booth, they felt average.
"Wow..."
The seniors each let out sounds of admiration at the sight.
The man narrowed his eyes with interest as well.
That reaction gave me courage, and we slowly lowered the last piece of cloth around our waists.
With a creak, our buttocks were revealed.
Pink flesh peeked through the dense forest.
I hadn't thought much of it before, but seeing Mizuki's pale mound made me compare myself.
Mizuki, do you even manage down there...? I should've taken better care of mine too...
Now we stood completely naked in the middle of the noisy event area.
It was only because we had to change into new clothes...
"Wow~ Both of you really have huge breasts! Maybe we've found some promising talents~"
"Right, right! Yuna has this healthy vibe~ Feels very much like an athlete!"
"Mizuki's skin is so pale~ Her nipples are really pretty too!"
The seniors' eyes sparkled like innocent children as they admired our naked bodies.
Thank goodness.
The seniors seemed like good people too.
Immediately, two seniors crouched behind each of us.
I could feel their breath right behind my buttocks.
"Time really flies~ When I first joined, another senior helped me change like this too."
With a nostalgic expression, the senior began skillfully and gently wrapping the white cloth around my stomach.
The Club President chuckled and spoke to her.
"You were so nervous back then that you farted right in her face. Everyone teased you about that for a while."
"Club President, seriously! At least maintain some dignity in front of the new members~!"
Even as she said that, she blushed and laughed heartily.
As if reminiscing about precious memories with close friends.
What a warm and friendly club.
I wanted to get close to them quickly too.
With that thought, I surrendered my body to the sensation of the cloth wrapping around me.
It felt like I had become a baby wearing a diaper.
The cloth wound skillfully around my thighs and groin, and before long, the white fabric took the shape of the same T-shaped loincloth the others wore.
"Hyaa!"
When a finger slipped and brushed lightly against the cleft of my buttocks, a sound escaped me without thinking.
"Ah, sorry. Hehe, you're sensitive there, aren't you, Yuna?"
The senior casually smacked the spot with her palm once more.
Along with a chilling sensation, it instantly hardened.
Heat rose from below, and my mind burned white-hot.
"There! All done! Surprisingly simple, right?"
"This side is done too~"
The seniors stood up with proud smiles.
Their laughter was clear and lively, but it didn't sound louder than my own heartbeat.
Mizuki and I looked at each other with wide eyes.
Before we knew it, we had become just like the seniors we had first stared at in wonder.
Mizuki's eyes reflected the white fundoshi contrasting against tanned brown skin,
while my eyes reflected the white fundoshi harmonizing with pale skin.
"Wow... Yuna unni..."
"Mizuki..."
Both of us flushed bright red from head to toe with embarrassment, as if our blood vessels were about to burst.
But...
'Not very sumo-wrestler-like.'
That was the conclusion we reached.
When doing sumo, this was normal.
In the first place, we would have to collide and roll around while looking at each other's hot naked bodies from now on.
What was there to be embarrassed about?
We needed to get used to it quickly.
Mizuki and I met each other's eyes and nodded.
"Always keep your fundoshi clean and treat it with care. It's the basics for anyone who does sumo."
The man stretched and spoke to us.
His eyes were the same as before, but now they felt like a strict coach's gaze.
"Shall we head to the practice area, then? You two, follow me. The rest of you, please continue with the promotion. Ah, don't accept ugly girls or anyone below a D-cup, okay?"
"Yes! Leave it to us, Club President!"
"Have a good time~ Do your best, you two!"
The seniors picked up their signs again with renewed energy and saw us off.

We walked through the crowded event area.
Since we were from the Sumo Club, walking around like this was unavoidable...
Walking barefoot in fundoshi felt incredibly awkward.
Above all, the lecherous gazes from men other than the Club President that followed us as we passed were unavoidably unpleasant.
It was proper sportswear, yet some people still looked at us that way.
Men really are...
I wanted to kick them, but I held back for the sake of the Club President who was personally guiding us.
Mizuki seemed to have noticed those gazes too, as she followed behind me while staring only at the ground.
"Don't worry, Mizuki. If any weird guy approaches, I'll beat him up for you."
This cute girl, as always, smiled at my words and pressed closer to me.
"Hehe, thank you, Yuna unni."
Once we finally escaped the crowd, the Club President stopped in front of a wooden building in a somewhat secluded area.
"Alright, this is where you'll be rolling around from today onward. Let's go in."
When he casually opened the door, a musty salt smell and something like the scent of a women's bath stung my nose.
The interior was larger and cleaner than expected.
The floor was covered with soft sand deep enough to sink into, and strands of variously colored hair were scattered here and there.
"The floor is really soft~ There's also this strangely pleasant smell."
Mizuki said while looking around.
"You could call it the scent of females... Anyway, you'll get used to it if you come often."
"One hundred reps, begin-!"
Startled by the loud command, I looked to the side and saw other women in fundoshi gathered in the distance.
More seniors?
I should greet them...
"Begin-!"

They all raised their arms above their heads and began repeatedly squatting with precise movements.
With each dull thud, thud..., the seniors' large breasts swayed like waves in unison.
Sweat droplets flew and ran down their napes and cleavage.
Even in their flawless motions, their wet bodies created even clearer silhouettes beneath their sumo attire.
Their breathing grew rough, yet none of them wavered.
They simply focused diligently on their exercise with dazed eyes.
"Wow..."
Our mouths fell open on their own.
Even though we were from an athletic department, the unfamiliarity and overwhelming energy, so different from the taekwondo we had done until now, rose from within me.
"Ah, don't mind them. They're in the middle of their daily training. The sumo squats are good because they build lower body strength and also cultivate a female's vulgarity."
The Club President spoke to us with his arms crossed indifferently.
So training like that was basic.
I would be fine, but would it be too hard for Mizuki...?
"Since it's your first day, you won't be doing that, so don't worry. I just want the two of you to experience the fun of female sumo first."
He tapped my unmoving shoulder as if reading my mind.
"Ah... Yes!"
I straightened my posture.
The man drew two circles side by side on the sand with his foot.
"The basic rules are the same as regular sumo. You just have to push each other out of the circle. If you fall or step outside, you lose. But the difference is..."
The man poked my left nipple with his finger as he spoke.
"Hik...!"
"You can't grab your opponent with your arms or legs. You can only push with your breasts. That's all. Simple, right?"
"Ah... Yes..."
I nodded silently.
Only with breasts... to attack?
Ah, I see.
Of course, in sumo... you naturally have to push and collide with your breasts.
That's why he only recruited females with large breasts.
You needed big, ample breasts to properly push an opponent away.
I could hear myself nodding in agreement inside.
As expected, the Club President knew everything well.
I felt pathetic for having wasted time worrying about unnecessary things until now.
My nipples, even harder than before, continued to twitch as they remembered the touch of his fingertips.
"Do you understand, Mizuki?"
The man asked Mizuki.
Mizuki's face had turned bright red as she trembled.
"Y-Yes~! I understand!"
"Good. Then Choi Yuna, let's have a match with me first. I'll teach you the details as we go."
The Club President's two feet stepped into the circle.
I could learn directly from the Club President.
Alright.
Choi Yuna, pull yourself together.
Let's learn properly.
Female sumo.
