The Principal and Yeon-woo's... Photo Shoot
“Ah, fuck... so fucking horny... huff... huff...! Instructor Yeon-woo... it feels so good...”
Full 19 years old. Freshly adult Beom-jun Kang was overflowing with sexual desire just like any other guy his age. And on top of that, wasn't he a re-taker crammed full of stress? After holing up in the cramped cram school all day studying and coming home, there weren't many better dopamine producers than jerking off to relieve that pent-up stress. Gaming took too much time, and scrolling YouTube or Reels was a hassle too. Handjobs were quick, easy, and got the job done.
But while most guys relied on AV actresses, Beom-jun was different. He had prime jerk-off material right nearby—someone he could actually see face-to-face.
“Ah, so fucking pretty... shit...”
Naturally, it was Mabong Self-Study Re-taker Academy's flower, the academy's sole beauty (there was some accountant in the office, but she was a total hag), Yeon-woo Lee.
Just recalling the time he bumped into her during office hours—no wild fantasies needed—made his cock twitch and harden. Massive tits, tiny waist, and hips and ass that were blatantly huge. Insane... And while most big-boobed girls had bulky upper bodies, Instructor Yeon-woo had a slim, lean frame overall, with long, slender limbs.
Did she get surgery? But the way they jiggled when she walked didn't look fake... Plus that idol-pretty face, and a head so small it defied human proportions. Her overall proportions were unreal. Hell, even her skin should have been flawed at that level of perfection, but no—it was milky white and flawless. So even in plain clothes, just staring made precum bubble up from his tip involuntarily.
But—
What the hell was that thing I saw yesterday...?
That image of her and Cheol-gyu Lee emerging from the motel kept popping into his head. Even plain old Instructor Yeon-woo got him on the edge now... and layered on top were these lewd 19+ scenarios. His heart pounded like a drum.
It's just my imagination, right? He tried to convince himself, but no explanation made sense for why a cousin brother and cousin sister would exit the same motel. Inevitably, dark fantasies straight out of erotic stories or porn flooded his mind.
And he didn't even need to rely on imagination anymore. Lately, Instructor Yeon-woo's Instagram was uploading like crazy. The heat level was off the charts.
“Insane. With all the students watching...”
Instructor Yeon-woo had to know. Honestly, almost every male student she saw daily was probably stalking her Insta. And yet she kept posting these... slutty photos?
“Ah, I can't take it... Instructor Yeon-woo... I wanna cum on your face...”
Tap-tap-tap-tap— Beom-jun's hand sped up, beads of fluid gathering on his cleanly circumcised glans. He'd propped up his wide-screen tablet with her pretty face filling the display. Pressing his tip against it felt like busting right on the teacher's face, ramping up the thrill.
He was just about to blow his load all over Instructor Yeon-woo's face—no, the tablet screen—
“...I'm home.”
A weary voice late at night. It was his older brother, Beom-geun Kang.
“Ow, shit...!”
Of all the timing! Right on the brink! But the chill of panic made Beom-jun yank up his pants and swipe up on Yeon-woo's photo to switch screens. All in under two seconds.
And then— slam! His brother barged in without knocking.
Like any brothers, Beom-jun hated his hyung invading his personal space.
“Hey. What're you doing?”
“Ah, fuck. Studying, obviously.”
His voice trembled for a split second. No way he suspects, right?
But...
“Bullshit. You were jerking off, weren't you?”
“W-what? What the hell?”
“It reeks. And you're panicking hard.”
This guy got a dog's nose or what?
“Get out!”
“You little shit, talking to your sky-sent brother like that? Want me to cut your allowance?”
“...Sorry.”
His older brother Beom-geun Kang, years his senior, was an elite who'd aced med school. Already a second-year resident pulling a fat salary, but too swamped to spend it, so he was generous with pocket money.
“Where's Dad?”
“Dad? Hasn't come home yet?”
Lately Dad had been coming home late a lot. Weird part was, he claimed work dinners but rarely smelled of booze. Some midlife hobby maybe?
“Mom's asleep, right?”
“Probably. Hey hyung, didn't you have that blind date last time?”
“What? How'd you know?”
“Mom mentioned it. Said she's a nice girl, hopes it works out, but worries 'cause you're always so busy.”
“Heh heh... Already got after-date drinks approved.”
“Ooh... pretty?”
“Fucking gorgeous. Thought she was a celeb.”
“For real? What's her name?”
“Pfft. What, you gonna use your bro's future wife's name for what?”
Beom-geun ruffled his still-cute little bro's hair affectionately and left, in a great mood. He'd been thinking nonstop about that woman from the recent blind date—Yeon-woo Lee's face... and that body. Felt shallow and guilty, but her curves were killer. That pretty face and those eye-magnetizing huge tits. Perfect, right? Despite being a doctor, he was average-looking and shy, so he'd had zero confidence... but she'd greenlit after-drinks and even a date. Originally weekend plans, but with tomorrow's night shift covered, he'd begged via text and she coolly said yes. Felt like a palace maid chosen by the emperor. For detail-oriented Beom-geun, it was heart-exploding excitement.
Ah, date with her tomorrow night~! Can't stop palpitating.
Whistling back to his room, Beom-geun held his phone—with the photo Yeon-woo had KakaoTalked him. A close-up of her stunning, glamorous face. He grinned like an idiot staring at it.
Oblivious that it was the same girl his brother had just been using as jerk-off fodder...
===== August 9th. 1 PM.
“H-hello... Instructor Yeon-woo...”
“H-hi...”
The teachers in the office after lunch jumped in surprise. Because...
“O-oh, your outfit today is... uh, looking good.”
“...Th-thanks.”
It was... a bit too breezy for work. Way too revealing.
Bottom half: a sheer, body-hugging H-line skirt that clung to her lower curves like a second skin... but so short and precarious it was blatantly a micro-mini. Bend over even a little and ass cheek would flash. And—was it his imagination?—her ass outline was crystal clear, with no panty lines where they should be. Brain-melting slutty skirt.
Sure, on the street it'd just be bold fashion worth a double-take. But this was a cram school for college exam re-takers, sacred ground for studies—even if they were adults.
Ahem... isn't that too short?
Yeah... should I say something?
...Nah, leave it.
The male teachers who should've scolded her just exchanged glances, hesitating between awkwardness and... some perverse urge.
And the top wasn't as shocking as the skirt, but it was a string halterneck with full armpit exposure and deep cleavage—another outrageous reveal. As a Q&A instructor, raising her arms even slightly would flash pits, a nightmare for certain fetish students.
And the real shock was the back. Barely held by strings up front, the back was wide-open exposure: shoulder blades, erector spinae muscles down her spine, all on display. Jaw-dropping.
Glance, glance.
Everyone unsure where to look, but eyes kept drifting shamelessly to Yeon-woo's exposed skin... especially certain spots.
“...”
But Yeon-woo, who showed up in this bold outfit so confidently, didn't wear the haughty expression you'd expect. Instead...
Ah... so embarrassing...
She looked utterly humiliated, creating this weird gap that stirred something lewd in the watching men. Hard to pin down, but it was like she'd been forced into this by someone...
“Instructor Yeon-woo, you're h—oh, wait...?”
Then the academy owner, Principal Son In-su, came to the office to see her and froze.
=====
“No... Instructor Yeon-woo. Even without a dress code here...”
“...S-sorry.”
Yeon-woo often wore bold, figure-hugging clothes, but always within office-look bounds.
But this...
“S-sorry...”
Even Yeon-woo, who loved exposure and had loose sexual morals as an OP girl...
This was too slutty for her right mind. Dragged to the principal's office, she sat on the guest sofa biting her lip, head down, staring at the floor. Nothing to say.
If I were a guy... what would I think of a woman showing up like this?
Slutty whore, attention-seeker—total trash talk.
But she couldn't tell anyone it was because her cousin blackmailed her into dressing like a prostitute slut after catching her.
So she just sat there, face flushed with shame, hands clamped over her crotch lest her no-panty groin peek from under the skirt, anxiously taking the scolding.
But...
“Hmm... alright. Ah, today... time to update the model photos, right?”
“...Huh?”
“You signed the contract last time. We're using you as our promo model ongoing. Didn't demand outfits this extreme, but... it's contractual, so we scheduled the shoot today?”
“...”
Did she? Kinda rang a bell... Promo pics were just casual snaps anywhere, Photoshopped and posted—no fixed date. But Principal Son said it, so maybe?
“Y-yeah, I think so. Ha, haha.”
Yes. It had to be. That way, she wasn't some psycho coming to work in whore clothes for no reason—it was just fulfilling her promo model duties with a hot outfit request. Rationalized.
“R-right? Hmm... shall we snap some now?”
“...Pardon?”
“Better take them here and explain to the other teachers there's a reason...”
“Ah! Y-yes, Principal.”
And just like that, she was roped into a photoshoot.
Mabong Self-Study Re-taker Academy promo pics. Summer special edition.
=====
“Hmm... alright, taking the shot.”
“Okay...”
The sudden “academy promo photo” shoot. They sometimes hired pros, but often did selfies or asked other teachers. Principal shooting wasn't weird.
Of course...
“...Hah... hah... g-good, perfect.”
The 40s uncle principal's gaze kept dipping into her cleavage or under her skirt hem—super annoying, but unavoidable.
Just like how Yeon-woo endured pervy acts under Cheol-gyu's blackmail. This outfit was forced by him too, but to elevate it to “official duty”...
“...Changing pose, Yeon-woo.”
“Sure...”
“...Grab that desk... and bend over a bit?”
“...Pardon?”
But...
Who takes 'academy promo photos' in poses like this...?
She couldn't help the doubt.
