In the calm, warm air that gently hinted at the arrival of spring, a wet, squelching, lewd sound echoed through the music preparation room.
“Ahh… aaahn!” Right now, I was pinning my classmate and girlfriend, Kumiko Omae, against the wall, taking her from behind in a standing doggy-style position.
Of course, it was completely consensual.
I never engage in any sexual act without love.
This is a world where only one in seven people are male.
A world where the values and societal expectations of women and men have been completely swapped.
While women are allowed to be crude, vulgar, or aggressive, men are expected to be chaste, refined, and modest.
The world I was reborn into had its entire sense of sexual morality flipped, along with a massive gender imbalance.
In such a world, I joined the brass band club.
To put it bluntly, I was in a state that could only be described as the “princess among princesses” — what would have been called an “otaku circle princess” in my previous world.
You might not understand just from hearing it, but that’s exactly how it felt.
In a society where men are already extremely rare, joining a brass band club where they are even rarer made me an absolute rarity.
Partly because I genuinely loved music, I became interested in wind instruments.
In my previous life, I had dealt with pops, rock, electronic music, and soundtracks.
Since I had lived a life completely unrelated to brass bands, I wanted a fresh kind of stimulation.
The instruments I used to play were basically “pole objects” — meaning guitars and electric basses.
I was a composer in my previous life.
Fortunately, several of my songs became hits.
I asked a singer I liked, who was on the decline, to stand on stage with the next song I composed.
As the planner and MC, I exited the stage while applauding, but I accidentally fell off the stage, hit the wrong spot, and died.
It’s what you call dying in the limelight.
Or “calcium light.” None of that matters now.
Right now, I want to concentrate fully on having sex with Kumiko.
Twisting my hips, I stirred and tilled the inside of Kumiko’s tight, wet vagina with my thick penis using a slow, rotating grinding motion rather than simple piston thrusting.
The lewd, sticky sounds of flesh rubbing against flesh filled the room.
Letting out high-pitched, sweet gasps, Kumiko pressed her hands against a heavy music book printed with the serious faces of Bach and Beethoven.
Having sex right in front of the great masters somehow made my spirit soar with excitement.
Perhaps feeling my meat rod growing even thicker and harder inside her, Kumiko called out to me happily, her voice trembling with pleasure.
“It’s… getting bigger inside me… I’m so happy you’re this excited… and feeling me so deeply…” “Sex after school has always been one of my dreams… And it can’t be helped because your pussy is so incredibly wet and erotic, Kumiko.” “Hehe… What’s that?
You sound like an old man,” Kumiko replied with a shy smile and a playful joke.
Apparently, she had been caught in a sudden rain shower during outdoor practice earlier.
Even though she was wearing her winter uniform, the fabric was clinging tightly to her body due to the moisture.
While she looked a bit cold, the way the wet uniform emphasized the soft curves of her modest but beautifully shaped breasts, slim waist, and gently rounded hips roused my “son” even more.
Kumiko has a delicate, cute face with large, expressive eyes and slightly wavy, dark brown hair that reaches just past her shoulders.
Her body is slender and feminine, with smooth, pale skin that feels incredibly soft to the touch.
Her breasts, though not huge, are perfectly shaped and sensitive, with cute pink nipples that harden easily.
Following those heated feelings, I continued thrusting into Kumiko right there in the music room after school.
Having sex at school after hours had been one of my long-held goals.
It was something unattainable in my previous life, but now I had fulfilled one of my dreams.
It made me incredibly happy.
I slammed my hips against Kumiko’s soft ass with a rhythmic *pan-pan-pan* sound.
“Ah!
Aah!
Aaahn!” Feeling Kumiko’s voice gradually growing louder and more dangerous, I hurriedly covered her mouth with my hand.
“Mmm~!” Kumiko let out a muffled voice of protest, but it would be bad if we were caught.
Well, it wouldn’t actually be a serious problem in this world, but it was just a reflexive reaction.
This world is very broad-minded about sex.
The motto is basically “Making babies, pregnancy — keep it coming!” It’s a timeline where it’s perfectly normal for high schoolers to be pregnant.
A world where there’s no issue with going to school while heavily pregnant or wearing a sailor uniform with a large, swollen belly.
It’s a world where people casually enter love hotels with the same ease as going to a karaoke box.
Naturally, I want my girlfriend Kumiko to get pregnant with my child.
With the sole intention of impregnating Kumiko, I pressed the swollen head of my penis firmly against her cervix and accelerated my movements.
As I sped up the piston motion, the wet, squelching sounds from Kumiko’s dripping slit grew louder and more obscene.
I felt the climax rising rapidly up my spine — a tingling, numbing pleasure.
At the moment my excitement reached its absolute peak, I discharged a massive load of thick semen deep inside her with a powerful *dobyu-buryuryuryu* burst.
“~!!!!” It seemed Kumiko also came at the exact same timing as my ejaculation, her pussy convulsing and squeezing me tightly.
The two of us collapsed together onto the floor of the after-school music preparation room.
The cold spring floor felt refreshing as it cooled down our flushed, sweaty bodies.
With my still-hard meat rod sandwiched inside her twitching slit, Kumiko lay on top of me, looking completely exhausted.
After all, we had done it three times in a row without much rest.
As expected, Kumiko seemed utterly spent.
She rested her head on my chest for a while, breathing heavily.
Still, sailor uniforms are truly wonderful.
Unlike pants, you can simply slide the panties aside and fuck immediately.
