Chapter Title: Dongseong's Full Joining, and Eunju's Appearance
-----------------------------------------------------------------
August 30th, second day of the semester, 7:40 PM to 9:20 PM.
Business Department empty classroom 306 (after evening self-study).
On the second evening after classes started, the campus had gone completely quiet once evening self-study ended.
Most of the hallway lights were off, with only the faint echoes of footsteps from students studying late and the occasional sound of doors closing.
The entire lecture building was nearly deserted, and the distant rumble of the cleaning lady's cart wheels felt like the only sign of life.
The door to classroom 306 was slightly ajar, with just one fluorescent light on inside.
The lighting was dim, leaving the corners of the room shrouded in shadow, and the blackboard still bore faded graffiti from last semester that no one had erased.
Scrawls like "Failed the exam fml" and "Prof is insane" stood out more sharply under the faint light.
The air was thick with dust and the musty smell from the AC, while outside the window, the night sky on the second day of classes hung deep and black, starless.
Dust had built up on the window frame all summer, stirring slightly whenever the wind blew.
Kang Siyun was perched on the desk at the front of the classroom.
Black short-sleeve tee and jeans, a half-melted iced Americano in hand.
His phone and small bag sat on the table, and inside the bag was the plastic container (of pills) he always carried.
Siyun chuckled lowly as he stared at his phone screen.
'Second day of classes...
Over break, I made all three of them completely mine.
Even got them into outdoor exposure play... now it's time to really get started on campus.
Dongseong, buddy, time to bring you fully onboard starting today.
Start by handing over the department rep slut...
Mijin's my main girl—no way she's up for sharing.
Only the casual snacks are on the table.
Main girls are girlfriends, casual snacks are just that—snacks for when I'm bored lol.
Can't wait to see that look on Dongseong's face.'
Siyun sent off some texts.
[Siyun → Sua] Department rep slut, get to 306 now.
Special guest today. Don't call Mijin or Yerin. Come alone.
[Siyun → Dongseong] Yo Dongseong, wait out front of the department office.
Grabbing the department rep slut now. Let's have some fun.
The door opened quietly first, and Choi Sua slipped in.
Sua was in her usual slutty style today too.
Thin white off-shoulder crop top + ultra-mini pleated skirt.
The crop top rode up about 12cm above her navel, baring her slim waist completely,
and its deep plunge showed the clear outline of her nipples. (No bra.)
The ultra-mini skirt was so short it'd flash everything if she sat,
and with no panties, her inner thighs glistened with every step.
A few students in the hall had glanced her way, but Sua was completely used to the stares by now.
If anything, they only turned her on more.
The 'Casual Snack #2' choker glittered around her neck.
The moment she shut the door,
Sua approached Siyun with a blissful smile.
"Master... second day of classes, and you called me already... I'm so happy♡
I wore off-shoulder and an ultra-mini skirt today... I felt everyone's eyes on me in the hall♡
Didn't call Mijin-unnie or Yerin like you said... came alone♡
Special guest today, right? I'm so excited♡
The stares in the hall... my pussy got wet, and the fabric rubs every step♡"
Siyun lifted Sua's chin slightly.
"Good girl, department rep slut.
Special guest today."
"Wait here. Get in position."
Sua struck the pose immediately.
She hiked up the off-shoulder crop top to cup her breasts,
and lifted the ultra-mini skirt just enough to flash below.
Beaming happily,
she gazed at Siyun.
"Master... like this?♡
When oppa gets here... I'll do it for him too♡
Breasts... nipples... pussy... all oppa's♡
Going to oppa in front of Master... feels so good♡"
The door opened again,
and Kang Dongseong stepped in.
Dongseong, back on campus for the second day after his leave,
was in casual checkered shirt and jeans, textbooks still not sorted.
His nearly 180cm frame and broad shoulders stood out even in the classroom.
Dongseong gulped as he shut the door and saw Sua.
"Whoa... Sua?
Why the hell are you dressed like that?
Department rep in off-shoulder and ultra-mini skirt...
What is this on day two?"
Sua turned her blissful smile on Dongseong.
"Dongseong-oppa... long time no see♡
Thanks to Master... I'm happy every day now♡
Slutty outfits... if oppa likes them... it makes me even happier♡
Today... I'll make oppa happy too♡
Breasts... nipples... pussy... touch them as much as you want♡
Going to oppa in front of Master... feels so good♡"
Dongseong panicked and shot Siyun a look.
"Yo Siyun... what's going on here?
Why's Sua acting like that with you?
And making me happy too... what the fuck?"
Siyun chuckled lowly.
"Dongseong... Sua's my casual snack #2 now."
"Handing her over to you starting today.
Enjoy her all you want."
Dongseong froze for a second,
then slowly looked back at Sua.
Sua held her pose,
smiling blissfully as she spoke.
"Dongseong-oppa... Master gave permission♡
Today... I'll take proper care of oppa too♡
Breasts... nipples... pussy... touch them all♡
Going to oppa in front of Master... feels so good♡"
Dongseong swallowed hard,
and approached slowly.
"This... for real?
Siyun... you're insane..."
Siyun lounged on the desk, arms crossed,
watching with a grin.
"Dongseong... Sua's a casual snack.
A toy to play with when bored."
"Mijin's different.
She's my main girl.
Think of her as my girlfriend."
"Main girls are off-limits. Never sharing.
Casual snacks... I can pass them around anytime."
"Yerin and Sua are yours too.
Call them whenever."
Dongseong tentatively groped Sua's breasts.
Sua let out a happy moan.
"Ah...♡ Dongseong-oppa... there... so good♡
Harder... going to oppa in front of Master... feels so good♡"
Dongseong grew bolder,
pinching her nipples.
Sua's moans grew louder.
"Haa...♡ Oppa... nipples... so rough... it's the best♡
Master... watch♡ I'm taking good care of oppa♡"
Dongseong laid Sua back on the desk.
He spread her legs
and hiked the ultra-mini skirt all the way up.
No panties, and she was already soaked.
When Dongseong slid fingers in,
her insides clenched wildly.
"Eung...♡ Oppa... so deep...♡ In front of Master... going to oppa... so happy♡"
Dongseong panted,
dropping his pants.
Sua smiled blissfully,
spreading her legs wider.
"Dongseong-oppa... put it in♡
In front of Master... I want to go to oppa properly♡"
Dongseong pressed against her entrance.
Thrust in slowly.
Sua's moans filled the classroom.
"Aaaah...♡ Oppa... so big...♡ Master... watch♡
Going to oppa... feels so good♡"
Dongseong started moving.
Deep, hard, slow.
Sua kept moaning happily.
"Haa...♡ Oppa... harder...♡ In front of Master... going to oppa...♡
Breasts... nipples... all yours♡"
Sua's body convulsed hard.
She climaxed.
Smiling blissfully,
Sua hugged Dongseong.
"Dongseong-oppa... thank you♡
Master... I took good care of oppa too♡
Casual snack #2... I'll make oppa happy too♡
Call me anytime♡"
Dongseong panted,
glancing at Siyun.
"Dude... Siyun... this is insane."
"But... fucking awesome..."
Siyun turned off the video,
grinning.
"Dongseong... how's that?
Casual snacks taste good, right?"
Dongseong nodded.
"Bro... seriously... the best."
"But why not Mijin for real?
She's gorgeous too.
Big tits and everything..."
Siyun chuckled lowly.
"Mijin's my main girl.
Think girlfriend.
Main girls are mine only. No sharing.
Casual snacks are toys for when I'm bored."
"Yerin and Sua are yours too.
Call whenever."
Dongseong grinned.
"So... am I a casual snack owner now too?"
Siyun nodded.
"Yeah.
Casual snack owner.
But main girls are mine alone.
Touch them and I'll get pissed."
Dongseong laughed,
stroking Sua's hair.
"Sua... looking forward to more♡"
Sua smiled blissfully,
burying her face in Dongseong's chest.
"Dongseong-oppa... call me anytime♡
With Master's permission... I'll make you happy too♡"
Then
the classroom door creaked open slightly,
and an unfamiliar shadow appeared.
It was one-year senior Eunju.
Eunju's face was a touch less pretty than Mijin's,
but her breasts were definitely bigger.
Overwhelming 75F-G cup volume.
Today she wore a tight white knit + jeans,
the knit straining so hard over her chest the buttons looked ready to pop.
Eunju peeked inside and looked mildly shocked.
"Huh...? Siyun? Dongseong?
What are you doing here?
Sua... why are you dressed like that?
Your tits are totally see-through...
And... what was that noise just now?"
Sua turned her blissful smile on Eunju.
"Eunju-sunbae... thanks to Master... I'm so happy♡
Slutty outfits... every day now♡
Sunbae... if you want to see... anytime♡
Your breasts are huge...♡ Master would love them♡"
Eunju flushed red,
stepping back.
"W-what the...?
Siyun... what is this?
Dongseong, why are you here too?"
Dongseong gave an awkward smile,
looking at Eunju.
"Sunbae... long time no see.
Me too... starting something fun today."
Siyun approached slowly,
lifting Eunju's chin gently.
"Sunbae... your tits are huge.
Way bigger than Mijin's...
Wanna get inspected?"
Eunju's face turned beet red,
backing away.
"Hey... are you crazy?
I'm your senior..."
Siyun grinned.
"Sunbae... when your body heats up... come find me.
I'll be waiting.
I really like big-titted girls."
Eunju flustered,
bolted from the classroom.
The door slammed shut.
Siyun chuckled lowly at the sound.
'Eunju-sunbae... tits bigger than Mijin's.'
'Your turn soon.'
Dongseong watched from the side, laughing.
"Yo Siyun... next target's Eunju-sunbae?"
Siyun nodded.
"Yeah.
I like big-titted girls.
Dongseong... you into her too, right?"
Dongseong laughed, nodding.
"Dude... honestly... fucking massive.
I wanna grope 'em sometime."
Sua smiled blissfully,
alternating glances between them.
"Master... Dongseong-oppa...
Eunju-sunbae will be happy soon too♡
Like me... Master's♡
And... I'll share with oppa too♡"
Siyun stroked Sua's hair, grinning.
"Good... Sua.
You're casual snack #2 now,
so take good care of Dongseong too."
"Eunju-sunbae... joining our collection soon."
Dongseong hugged Sua's waist, laughing.
"Yo... Sua.
Looking forward to more♡"
Sua smiled blissfully,
burying her face in Dongseong's chest.
"Dongseong-oppa... call me anytime♡
With Master's permission... I'll make you happy too♡"
Siyun watched them,
chuckling lowly.
'Dongseong... you're officially in my harem now.'
'Eunju-sunbae... your tits are mine soon.'
The second day of classes ended like that.
