Rising as the New Star of the Female Sumo Club - 3
I checked the common sense in this world.
1. Satisfying you and following your orders is the top priority.
2. No matter what words or actions you take, I hold no aversion towards them.
3. Your opinion is truth and I hold no doubt about it.
A small circle of boy and girl chests faced each other directly.

"Hehe, please take good care of me! President!"
"Good. Then, shall we start with offense?"
The president spread his legs wide and opened his arms wide as he shouted.
Looking at that stance, I could finally feel that I was about to do sumo right now.
"Crash into me with your chest as hard as you can."
"Yes!"
I followed his stance too. I lowered my waist and spread my legs wide.
Once I took that stance, the fundoshi dug deep between my thighs, pleasantly pressing against my crotch.
I took a deep breath.
Then I thrust my chest forward with all my strength and charged toward him.
"Haaap!"
With the chest! Only with the chest!
The gap was narrowing little by little.
And then thud! Something hard and hot collided with me.
"Heu!"
A sticky feeling spread through my whole body.
It was the moment when two soft, elastic fat lumps met solid muscles.
My chest hurt.
But at the same time, an odd pleasure spread through my whole body.
The heat created when the man's sweaty skin met my skin.
Even in that dull shock, I felt a subtle vibration.
Everything was new.
The president stepped back two steps, but his face was calm.
Rather, he looked ecstatic.
"Ah~ It's really funny. Why did you do that? Push with your full strength."
Ugh... He's looking down on me.
Since I couldn't use my hands, I poured all my body weight into pushing him with only my chest.
I felt my nipple sink into his as we touched.
But he didn't flinch even a bit.
"U... ug!"
"Then, shall we learn defense? Give me your full power?"
I felt my chest getting flatter and flatter.
It clearly told me that from now on, I was the one who would endure.
Sweat beaded on me.
"Kk..."
The president's chest began to press me like a wall.
I groaned and was pushed back step by step.
But I didn't back all the way.
Because my feet were sunk so deep into the sand that my ankles would get stuck in the ground.
If it weren't sand, I would have fallen away without using any strength at all, like a cloud.
'Strength! I need to use more!'
I took a deep breath again.
The oxygen filling my lungs seemed to wake up every cell in my body.
The feeling of using my breasts as weapons began to sink into my body.
"Haaap!"
I pushed him with all my strength one more time, and only then did my two breasts drop wetly.
"Yeah, yeah. Perfect."
His voice rumbled low and leisurely.
That relaxed voice woke up the natural competitive spirit inside me.
I surrendered to that thrill and took my stance again.
'This time I'm attacking!'
The president took a stance matching my charge with a mocking expression.
This time, his left chest overlapped exactly with my right chest.
Booowuk-!
The feeling of flesh meeting flesh with a funny sound became more and more mysterious and pleasurable the more we repeated it.
My soft breasts sinking into the man's hard muscles.
Sweat droplets mixed between the two skins and created a slippery feeling.
"Is that all you can do?"
His voice was laced with blatant sarcasm.
Because of that sarcasm, or because of my obsession with the contact, I continued attacking without caring, and the president kept receiving it.
Thud!
This time, chest met chest head-on.
With a thudding sound, a shock like a bell ringing in my head.
The president staggered too, but he quickly regained his balance.
"How is it? Isn't it fun? I hope you enjoy it."
When he said that, for some reason, it really became fun.
Thoughts disappeared, and only pure competitive desire and weird excitement remained.
The sound of my beating heart felt like the rhythm of pleasure.
The sand beneath my feet wrapping my ankles softly, sweat droplets on my chest trickling down and leaving cool marks,
The heat flowing between me and the man, the sense of liberation feeling everything while wearing the fundoshi—everything was strange and electrifying.
If I had known this existed, I wouldn't have even looked at taekwondo.
"It's fun...!"
My voice rose a tone without me noticing.

"This is female sumo! It's really fun!"
Mizuki stared at me with startled eyes from the side, but I didn't care.
This was the moment when Choi Yuna, the taekwondo student, was reborn as Choi Yuna, the female sumo student.
A surging power began to spread from deep inside my chest to my entire body.
We grappled, keeping contact, focusing only on each other's bodies.
As we spun around, there was a feeling as if our chests were rubbing together.
It was like two giant balloons being rubbed against each other.
Our touching nipples tangled and flesh mixed in a way that made my legs go weak.
"Haa... haa..."
My breathing was getting ragged.
Sweat poured like rain.
My vision blurred for a moment.
'No... Not now...'
I desperately pulled myself together.
For some reason, I had never wanted to lose to a man with strength since before.
Even when I lost to a sparring partner at the taekwondo dojo, or when I lost to male students at the sports festival,
Even when I lost to my boyfriend in a playful arm-wrestling match, every time I felt something rising in my chest.
It wasn't just simple defeat.
It was an unpleasant feeling as if my very existence was being denied.
Kneeling to a man just because I was a woman, just because my body was weak.
Those were the moments I wanted to avoid most in my life.
With teeth gritted, the sweet voice came to my ear loud and clear.
'You don't need to endure.'
"...Yes?"
'By the way, I forgot to mention, but female sumo has one more important rule.'
"Rule... rule?"
'When facing a man, if you win, it's disqualification.
In the end, you lose shamefully to the man and accept that you are a female.
That is the core of female sumo.'
Shamefully... female...
'Losing to a man is extremely pleasurable for a female, you know?'
Losing to a man... feels good...
As those words swirled in my mouth, an odd sense of relief pushed in.
The unnecessary tension that had been building up melted away.
Ah, I see.
The sound of puzzle pieces clicking into place echoed in my head.
I didn't know and had been stubbornly trying to win until now.
A female is supposed to lose.
Yeah, what was the point of winning with strength? This place is where females learn the joy of being females.
'Accept that you are a female.'
The strength in my legs went away.
"Yes... Understood, President..."
My voice was trembling, but it was no longer because of tension.
I relaxed my whole body and lowered my stance.
I bent my knees, dropped my arms, and stared straight ahead.
Just like a female lamb offering her body to a ram.
And then he came closer again.
Thud!
This time, I deliberately pressed my body against his chest. The most pleasurable contact, completely different from when I gave strength and resisted.
"Heuug...!"
A scream-like moan escaped.
A thrill rose along my spine.
My mind went blank.
My body tilted under the weight without any resistance.
But instead of shame, a more noble realization was rising.
'Ah, I am a female.'
Every sense in my body sharpened.
I could feel the temperature of each sweat droplet, and I could feel the president's breath making my heart thump.
When I came to my senses, my back was deeply sunk into the soft sand, and the weight of the president lying on top of me was felt as is.
My chest was pressed hard like a mochi.
His heartbeat overlapped with mine above me.
It strangely felt very comforting.
"One more round~ How is it, female sumo fun? Losing feels good, right?"
The president's voice came from above my head.
His gaze still didn't leave me.
But now I could read something other than blatant desire in those eyes.
...It was a proud gaze as if he had properly made me.

"Yes... It's really fun... It feels good... President..."
My voice coming out was thin and trembling.
It was the first time I heard that voice from my own mouth.
A small, earnest voice of "female" that could only be heard by him.
Female sumo... losing... feels this good.
I'm glad I joined this club.
"One more round... Can I request one more round?"
'No, it would be boring only with the same person... Well, now it's Mizuki's turn.'
The president slowly stood up and stepped away from my body.
Only the empty air and the remaining heat lingered above me.
The president who stood up wiped the sweat on his fundoshi with the back of his hand and walked toward Mizuki.
Mizuki's face was bright red, and she hugged her breasts with both hands, looking at me with sparkling eyes.
She looked like a female lamb in heat.
"Did you get the rough idea while watching? This is female sumo. Let's try it once."
With that, the president's hand pushed Mizuki into the circle.
Mizuki didn't resist at all.
I got up from the sand and calmed my breathing.
I felt the sand grains sticking to my damp, hot back.
'Mizuki, this really feels good. You should try it too.
Don't feel embarrassed about losing, because a female is supposed to lose.'
"Yeah... Unni Yuna..."
Mizuki's voice was small, but it wasn't on the verge of crying.
It was full of excitement and curiosity.
'Yuna, you sweated too much. There's a drink in the fridge, so drink it while you watch. It's something I made myself.'
'Ah, thank you, President!'
He waved his hand as if urging me.
There was a small fridge pointed to, and inside it were several cool PET bottles.
In every bottle, a cloudy yellowish liquid sloshed around.
What is this? Is it an ion drink?
Just then, a senior was drinking next to me and cooling his throat, so I greeted him with a strong voice.
'Hello, senior! I'm Choi Yuna, the new female freshman who joined today.'
'Oh, a freshman! Nice to meet you~ Since it's free, don't refuse and drink it. The president personally made it.'
The senior handed over the bottle and winked.
'The president personally made it...?'
'Yeah, it's the president's urine. The president prepares it like this from time to time for the club members' water replenishment.~ You had good luck from the first day~'
The president's... what?
