Sohyun's Strange Behavior
“Sent the money.”
“Thanks.”
“Don’t run off.”
“I’m not that kind of person.”
“Just kidding.”
A few words exchanged, and suddenly courage welled up inside me.
My inner wimp has grown a spine!
Conversations with Sohyun felt a bit easier now.
“I’ll pay you back as soon as I get my paycheck. Thanks, Oppa.”
“Sure.”
“Come by my mom’s snack shop sometime. I’ll hook you up with extras.”
“If you eat with me.”
I surprised myself today I was surprised after saying it.
My courage had ballooned out of control.
Sohyun’s expression didn’t change, but her eyes narrowed just a touch.
“Sure. When do you want to go?”
“Huh? For real? Uh, yeah.”
“Then I’m off. Gotta help Mom.”
“This late?”
“Lots of people come for hangover noodles.”
Sohyun stood and turned away.
College, PC bang part-time, helping her mom.
Sohyun really hustled.
Damn, that’s cool, I thought.
“Someone that pretty could make bank just streaming.”
Honestly, plenty of people would buy her as an idol.
“She’s got her reasons.”
I headed home.
Rooftop room on the fourth floor of the building.
That was my place.
“Huh?”
She left some again today.
The landlord on the first floor ran a side dish shop.
So she always left these for me.
Unsold stuff, but it made for solid late-night snacks or breakfast. I was grateful.
“Thanks for the food, ma’am.”
I thanked her in my head.
Stashed the sides in the fridge.
Flopped onto the mattress that passed for my bed.
The light flickered.
Flickering again. Should’ve bought a new one.
I just turned it off.
Darkness fell. The pitch-black room usually felt oppressive.
Not tonight.
-I, Yu Sohyun…
I replayed the video we’d shot as an IOU.
“She’s seriously pretty.”
I studied every inch of Sohyun’s face.
Couldn’t stare like this normally, so my eyes widened on their own.
Everything was perfect, but her lips especially.
Just looking made me feel good.
“No. Don’t go there.”
Dirty thoughts crept in uninvited.
Those pretty lips around…
“Ahem. Time to sleep.”
Got to hold back impure thoughts about Sohyun.
Still, the video kept loneliness at bay tonight.
Slept, woke, headed to the school library to study.
Re-enrollee, so all my peers had graduated.
Juniors found me intimidating.
Skipped club meetings too.
Loved soccer but held back.
Get hurt, and no part-time gig.
Studied at the library a bit.
Then evening hit, back to the PC bang for work.
“Welcome, Oppa.”
“Hey, Sohyun. Hi.”
Sohyun looked pretty today too.
“Interest.”
She set a cola next to me.
“Thanks.”
Still her usual blank face.
But it felt like we were closer.
Worked like normal today.
Boss could fire me if I slacked.
Can’t miss seeing Sohyun.
We were getting closer now.
So I hustled.
No boss yelling today.
Until late evening, when a drunk group came in ordering ramen for hangovers, delaying cleanup.
“Hey!”
The scolding started again.
Kinda curious now.
Common sense change or not.
Wondered what the boss was thinking, taking the slap.
“Boss.”
“What.”
“Why do you stick your cheek out after I slap you?”
“Why? That’s just common sense.”
“If I don’t hit you, you don’t get hit, right?”
“You gonna stop? Fine by me.”
“Do other part-timers hit you after scoldings?”
“Nah, just you.”
“So why only me?”
“Hey, quit asking dumb shit and get back to work.”
“I haven’t hit you yet.”
“...Fuck.”
Boss stuck out his cheek slightly.
I slapped with moderate force this time.
“Ugh, stings. You little shit.”
System was definitely on my side.
Tonight’s gonna be fun.
Tutorial over, real version starts now.
Changes would likely benefit me.

It’s started.
Wonder what changed this time.
Focused on me, so I’ll keep an eye out.
“Skin for the reward, huh.”
Not bad.
Good skin boosts your image these days.
Military training had roughed mine up a bit. Perfect fix.
“Careful going home, Oppa.”
“You too.”
“My mom’s snack shop. Let’s go after my paycheck next week.”
“Sounds good.”
“Get inside safe.”
Small stuff.
But spending time with Sohyun felt nice.
“What’s this week’s?”
Like the boss offering his cheek, it’d be obvious.
Next day, same routine, clocked in at the PC bang.
“Welcome.”
Sohyun greeted me as usual.
White blouse and skirt today—office look.
Made her seem more mature, even prettier.
No wonder customers flock.
Worked my ass off.
After 10 p.m., crowd thinned.
“Oppa.”
“Yeah?”
“Um…”
Sohyun’s cheeks flushed slightly, her usual blank face cracking.
First time seeing her embarrassed.
“What’s up?”
“What do you wanna see?”
“...Huh?”
“Tell me quick.”
“...Like what?”
“Ugh, you know. That thing.”
“...?”
Sohyun was definitely acting weird.
“Forget it. I’ll just show you myself.”
What the—
Pop, pop—
She unbuttoned her blouse one by one.
“...!!!”
Pulled it open slightly, revealing her black bra underneath.
Her massive cleavage jiggled into view.

My eyes bugged out.
“That good enough?”
Face beet red, Sohyun slammed her shirt shut.
That soft, jiggly cleavage vanished from my sight.
Regret hit hard—I hadn’t gotten a good look.
“...What was that?”
“What? You know exactly.”
“...”
Oh! That’s it.
Instinct screamed common sense alteration.
No other way Sohyun would do this to me.
Even if she liked me, not this sudden.
Liking me wasn’t even on the table.
What the hell is it?
Throb—
Fuck.
Just a black bra and cleavage.
My dick surged anyway.
Prime of my life, and Sohyun’s tits were lethal.
“Back to work.”
“...”
Ask for another peek, get slapped?
It was so hot though.
No, rimmed hot.
Picture it. Burn it in your brain.
***
Got home, pondered deep.
“What could it be?”
Like a common sense quiz.
Racked my brain on why Sohyun did that.
“No reason fits.”
Only odd thing lately: lending her money.
She’d pay back with her next check.
“Not that.”
Paying with her body instead?
Nah, shook my head.
Didn’t add up.
One sure thing.
“She won’t explain till I guess right.”
Like with the boss’s cheek.
“Hahaha.”
Dry laugh escaped.
Whatever, I saw Sohyun’s cleavage.
Proved changes benefited me.
“Tomorrow too?”
Throb—
Seeing her secret bits.
Cock throbbed, so I dropped pants and briefs.
Closed eyes, replayed the scene, stroked myself off.
Just cleavage, but.
“Hoo.”
Young and virile, easy enough.
“Not my fault. Yours, Sohyun.”
Hoped she’d do something weird tomorrow too.
Next day, clocked in same as always.
Sohyun acted like yesterday never happened, back to normal.
Stoic face, hard worker.
Then things slowed.
“...What today?”
Face flushing again, she asked me.
Did the same yesterday.
Told me to say it.
Showing me what I want to see?
Blue tee and skirt today.
Under the skirt… curious.
Possible?
Her face burned red, waiting on me.
“Not gonna say?”
“...Panties?”
“...Pervert.”
“...”
She flinched, embarrassed.
Then lifted her skirt slightly, flashing white panties.

“...Wow.”
“Good enough? That’s it for today.”
“Didn’t see it properly…”
“I showed you. Clearly.”
Regret again today.
Wanted the cameltoe through the panties.
Still… satisfying enough.
Caught those springy thighs when she lifted too.
Driving me insane.
Pretty face and killer body. What gives?
That night home, jerked off another load.
“What is it really.”
Post-nut clarity, mulled it over.
Once a day.
Seemed like she had to show me whatever I wanted.
Next day, asked Sohyun straight.
“Sohyun, why show me?”
“Why? We agreed.”
“Agreed?”
“...Quit embarrassing me when you know.”
“...”
Her face flushed hard again.
“So today… what?”
“...Hmm.”
Pussy possible?
Nah, too far.
She barely flashed panties.
Still want something hotter.
Eyes locked on her black pantyhose.
Extra sexy today.
Hiding after yesterday’s flash?
Wanted to see how they looked under the skirt.
Never seen ’em before.
So I said it.
“Lift your skirt… higher?”
“Again, that…?”
“...Just wanna see inside.”
“...Total perv.”
Embarrassed, but vibe said she’d do it.
Sudden greed hit.
Heart pounding, got excited without thinking.
“S-Sohyun. Sit on the chair… show me?”
“...Mean.”
“Oh, can’t?”
“Sigh. F-Fine.”
This works?
Sohyun sat in the chair.
Shyly spread her legs.
Wide open.
“Whoa…”
Eyes wide this time.
Saw it all: black pantyhose, black panties inside.

Fucking rimmed.
First time realizing pantyhose could be this hot.
Get why guys go nuts.
Nostrils flaring.
“Done for today.”
She closed her legs, bolted to the bathroom.
“...Insane.”
Crazy shit happening lately.
No, blissfully happy shit.
“Tomorrow… what to ask for.”
