I’ll Only Show It To You
Choa isn't exactly the type who enjoys working out.
During gym class, she'd always spend summer lounging in the shade under the trees and winter basking in the sunniest spot she could find.
Yet last December, she suddenly declared that she was going to start exercising regularly.
When I first heard about her goal, I thought it was pretty impressive.
The girl who used to roll around the house playing games all day was now grunting through squats. It made me smile like a proud dad.
Even as I watched her with admiration, though, I figured it would last three days at most.
But I was wrong.
Choa has been sticking to her home workouts for months now.
Not every single day, but three times a week.
She focuses mostly on bodyweight exercises centered around stretching.
Her once-awkward, half-bent squat form has transformed into something that actually looks like it belongs to a woman who works out.
Once she learned how to properly engage her glutes, her squats became far more effective.
And thanks to that, her ass has gotten firm and perky, turning into my personal pillow every weekend.
She was already blessed with an incredible body from birth, but adding consistent exercise has doubled that blessing.
“Is this your first time at a gym?”
“Yeah, first time.”
Choa was actually following me to the gym.
“So please take good care of me, trainer.”
“Trainer?”
“Today you're my personal one-day trainer.”
I haven't been working out long enough or well enough to actually be anyone's trainer.
Still, I could at least teach a beginner how to use the equipment and give basic form corrections.
“Alright.”
We arrived at the gym.
It was a small, locally-run neighborhood gym.
It didn't have the sleek interior or cutting-edge equipment of those big franchise chains, but it had everything you needed.
And because the owner was meticulous about maintenance, the place was spotless.
“……”
As usual, the owner was already there early in the morning, wiping down the machines. I gave him a light nod in greeting.
It was a typical gym thing. Even without talking, seeing the same faces regularly creates a kind of silent camaraderie.
The few people who had arrived before me and were already working out were all familiar faces too.
“Hello!”
While we guys were quietly acknowledging each other with that inner familiarity, Choa greeted the owner with a bright, refreshing smile like morning sunlight.
And just like that—
“Welcome!”
The usually stern-faced owner broke into a wide, blooming smile.
Owner…
In over a year of coming here, this was the first time I'd ever seen him smile like that.
So he could smile after all.
“Do you have day passes?”
“Of course we do. Absolutely.”
The owner practically jogged over.
“Coming to work out this early in the morning?”
“Yes.”
“Wow, you're really diligent!”
I'd thought he was the quiet type.
Turns out he was quite the chatterbox, like one of those neighborhood aunties.
The owner gave Choa a quick tour of the gym and explained how the day pass worked.
Choa listened politely, occasionally responding with soft exclamations of interest.
Having a beautiful girl actually engaging with what he was saying made the owner excited enough to start dumping all kinds of unnecessary trivia on her.
The people who were already working out kept stealing glances at Choa too.
There were even a few women among them.
Just like how guys admire a truly handsome man, women seemed to admire a genuinely beautiful woman in the same way.
It was nothing new, but…
Choa really was insanely pretty.
I'd gotten so used to seeing her every day that I'd almost forgotten.
“By the way…”
The owner lowered his voice and whispered to Choa.
“…Is he your boyfriend?”
Was he even trying to whisper?
He may have lowered his voice, but I could hear it crystal clear.
“No, he's not. We're just friends.”
Choa waved her hand dismissively.
A guy and girl showing up to work out together first thing in the morning could easily look like a couple.
But still.
Did she have to deny it so quickly?
Of course denying it was the normal thing to do.
It was just… really firm.
“Yu Choa.”
The owner, who had been buzzing with excitement ever since a beautiful girl appeared in his bachelor-scented gym, looked like he was about to hover around her all day. So I grabbed Choa's wrist and pulled her away.
“Go change and let's get to working out.”
“Okay.”
Choa headed into the women's locker room.
Now it was just two guys left.
Looking disappointed that he couldn't keep talking to her, the owner approached me with a sly expression.
“Member-nim, you've got some skills, huh?”
He nudged my side with his elbow.
We'd suddenly jumped several stages of closeness.
“When I first saw her I thought she was an idol. She's not actually an idol, is she?”
“No.”
Her face was pretty enough to be called an idol even without makeup.
And that girl…
With me…
The memory of what happened yesterday made my face heat up.
Choa seemed to think of it as nothing more than a casual greeting kiss.
But I couldn't see it that way at all.
No, I couldn't.
I like her.
I can't express it honestly, but…
Even the smallest, lightest skinship has always meant something incredibly special to me.
Every time we held hands in winter, she'd say my hands were warm and smile. But the truth is, my hands only get warm because she's holding them.
I hold her hands to keep them warm.
Every time she eats the food I cook and says it's delicious, I smile quietly to myself.
That's when I feel like all the effort I put into practicing cooking—just so I could feed her something tasty—was worth it.
To others, it might look like ordinary, familiar daily life.
But to me, every single day with her is incredibly special.
Will I ever be able to share these feelings with her?
Maybe yesterday, when we kissed, the beating of my heart actually reached hers.
Or maybe not.
“Hiii~”
Before starting my workout, as I was stretching, Choa came up behind me.
I was doing shoulder stretches when I turned around.
“What the…!”
I nearly had a heart attack when I saw what she was wearing.
I'd assumed she'd changed into regular gym clothes.
But Choa was wearing leggings.
Pink leggings.
They clung so tightly that the full, plump curve of her ass was on complete display.
On top, she had on a white bra top.
The deep neckline revealed the full roundness of her breasts and the deep valley between them.
“Is this girl crazy?!”
It was a common outfit for women at the gym.
But compared to the short sleeves and shorts she usually wore when exercising at home, this was way too bold for Choa.
I forced the windbreaker I'd been wearing onto her.
I zipped it all the way up to her neck.
“Why?”
Choa tilted her head like she genuinely didn't understand.
“It's too revealing.”
“Revealing?”
“Yeah.”
“It's not like I'm wearing a micro bikini. What's so revealing about this?”
Choa pulled the zipper back down.
I zipped it back up.
She pulled it down again.
I zipped it up again.
“Ugh, come on!”
Choa puffed her cheeks and huffed in annoyance.
“Says the guy who watches cosplay porn.”
“That's porn. This is different.”
Choa flapped the oversized windbreaker that reached all the way down to her hips and said,
“So you're telling me to work out like this?”
“Yes.”
I answered firmly.
If we were at home, maybe. But I couldn't allow her to wear something like that outside.
“Aha~”
Choa, who had been pouting with her lips pushed out, narrowed her eyes.
“You just don't want anyone else to see, right?”
“W-what?”
“If that's the case, just say so. Fine.”
Choa whispered in a small voice.
“I'll only show my breasts to you.”
“……!”
“Just kidding.”
Choa giggled.
“What? Did you actually get your hopes up for a second?”
“Shut up.”
“Okaaay, okaaay.”
I clicked my tongue.
“My childhood friend is so overprotective of me, it's becoming a problem.”
“Let's just stop talking.”
“I know the Confucian spirit is admirable and all, but girls aren't into guys who are too Confucian, you know?”
I realized I'd overreacted this time.
It was just normal workout clothes.
Very common.
It was practically the standard female gym fashion.
If I looked around the gym right now, there were already two other women wearing leggings and bra tops.
“……Give me back the windbreaker.”
I held out my hand.
I felt embarrassed realizing how much I'd made a fuss.
My behavior just now was exactly like…
A boyfriend checking his girlfriend's outfit.
Except I wasn't her boyfriend.
“You're really something, Park Siho.”
Choa laughed as she took off the windbreaker.
“What should we work on?”
I asked while stuffing the windbreaker into my bag.
“We should stretch before working out. Let's stretch.”
“Okay.”
There was a separate stretching area in the corner of the gym.
One entire wall was covered in mirrors.
Choa laid out a yoga mat on the floor.
“Now that I think about it, did you know? I'm actually super flexible?”
Choa stood on the yoga mat and slowly bent forward at the waist.
Her palms touched the floor, just like in a flexibility test.
“Whoa.”
But she wasn't done.
Choa folded her body completely in half like a flip phone.
“Whoa!”
I was genuinely impressed.
All those yoga videos she'd been copying must have paid off.
“I can do this too.”
Like an excited child, Choa showed me another pose.
She lay face-down on the yoga mat,
then stretched her arms forward like a cat waking up.
Her back drew a smooth curve as it arched downward.
Her breasts pressed flat against the floor like pancakes.
It was incredible flexibility.
But.
In the process, her ass lifted high into the air, and the sight was incredibly lewd.
That delicious-looking peach of an ass.
The round heart-shaped curve was perfectly emphasized.
And that wasn't all.
The plump, juicy outline of her pussy—looking like a fresh oyster—showed clearly between her thick thighs.
“How's that? Pretty flexible, right?”
Still lying flat, Choa wiggled her ass playfully.
I wanted to peel that peach right now and taste its flesh.
Just imagining pounding into her from behind was enough to make my cock twitch and harden.
“I think I can go even lower…”
Choa pushed her ass out toward me and glanced back over her shoulder.
Choa lying prone on the yoga mat, back deeply arched, ass raised high and presented toward me. Her pink leggings stretch tightly over her plump cheeks and the unmistakable outline of her pussy between her thighs. She glances back with a playful, teasing smile.
“Can you press down on my lower back a bit?”
