Teacher, It's Getting So Big
After sitting on the edge of Seol-ha Yeon's bed, I carefully undid my belt and pulled down my zipper. The silhouette of my cock was blatantly visible through my underwear.
"Hng...."
Seol-ha, squatting right in front of me, let out an intrigued, glistening hum through her nose and smiled. Her warm breath brushed against my manhood. My lower body twitched, and a ticklish sensation spread through my whole body.
Oh shit.
This thing's gonna get hard. Shockingly, I was actually excited by the situation. It's not like I'm some exhibitionist pervert. I was just feeling that thrill of immorality from baring my cock in front of a girl my age—a stunning beauty, no less.
Ugh. Does that make me a pervert? I couldn't help it. The way Seol-ha was staring right at my crotch, her gaze so lewd and bewitching... it was practically an act of God.
Still, I couldn't let it get erect. The vivid image in my head of Seol-ha sneering and teasing me over my swollen cock was too much. I'd die of shame for sure.
"Hurry up and pull down your panties too."
Seol-ha issued the command with a shady smile. Her eyes stayed glued to my groin.
I took a deep breath, squeezed my eyes shut, and slid my underwear down.
Flop— Finally. My cock dangled out, already a little swollen.
"First time seeing one for real... So this is a cock."
Seol-ha muttered to herself as she started inspecting my shaft. Call it my imagination, but her hot breaths carried a sultry edge.
First time seeing one in real life?
I blinked in shock at her words. Hard to swallow. No way—she was the one who straight-up demanded to see my dick. I figured she was a total slut. Was I wrong? Or maybe she was just messing with me. Maybe she clocked me as a total virgin loser and was playing innocent to reel me in. Then laugh when I got hard, mocking how turned on I got from hearing it was her "first."
This wasn't paranoia. These past few days desperately trying to teach her had taught me one thing: Seol-ha was scary smart. She came off as all playful mischief, always flashing that seductive smile my way. Skipped studying to goof off like a total wild child. But she'd never lost a single argument with me. Even now, she had me pathetically exposing myself like a fool.
If only this would get her to study. But would she? She was the chaebol tomboy heiress. She might just bail on the deal.
All sorts of doubts churned in my head, but the arousal wouldn't quit. I glanced down—Seol-ha's face was breathtaking. Those seductive cherry-blossom irises. Soft black hair wafting cherry shampoo fragrance. Cute, dainty pink lips. And the filthy breaths spilling from them, teasing my cock. She was like a gumiho summoned to ensnare every man's heart.
With a fox like that eyeing my crotch so coyly, it'd be weirder not to get horny.
Ah.
I couldn't hold back anymore. The humiliation of flashing my privates to my own student twisted straight into raw lust.
Twitch! Twitch!
My cock started writhing for real. I mentally belted out the national anthem, but no dice. Despite my silent pleas to calm down, it just kept swelling bigger.
"Huh? Teacher~ This thing's getting so big already."
Seol-ha's eyes widened a bit at my rapidly engorging cock, then she giggled and mocked me.
"No way—are you actually turned on? Showing your cock to your student?"
"......"
She nailed it; no comeback. I just gritted my teeth in silence. A grown man turned into a peer girl's plaything. I hated myself for it.
As my pride shredded in real time...
"Thought it'd gotten pretty big, but it's still kinda squishy~"
Tap tap—
"!!!"
Seol-ha had been humming appreciatively while eyeing my cock, but suddenly she poked it. Her pale fingers grazed the sensitive spot. The press of her perfectly manicured nails and soft flesh against my glans.
"What the hell are you doing?!"
I jerked back in shock.
"That's sexual harassment!"
"Pfft— So everything before now was fine? Looks to me like a teacher popping a boner from flashing his student is the real perv~"
I tried scolding her sternly, but I had zero authority left. Seol-ha shot back shamelessly with bullshit logic, grinning all the while. And kept tapping the tip of my glans.
The feel of someone else—the Sangyeon Group's beauty heiress, no less—touching my cock directly was intensely vivid and erotic. My hardness spiked instantly; you could see it firming up.
"Uh...."
That subtle, wickedly teasing touch had my swollen cock teetering on full mast. That's when—
"Ei."
Squeeze!
"Uh!?"
Suddenly, Seol-ha grabbed my cock outright. Her cool, silky palm wrapped the rigid shaft, making the whole length throb.
"Ah! Finally getting nice and hard! How's it feel now, Teacher? Good?"
"...N-not especially. And I said no touching. Just showing, and you'd st-study—"
"Hnnng~ But you never said no touching~"
With that, Seol-ha started kneading my cock. Flustered as hell, but my body didn't lie. Her palm had warmed up, and that softness... my restraint finally snapped.
Yeah. Full erection.
"Teacher... you're really feeling it now, huh?"
Did she sense my extreme arousal? Seol-ha beamed wider than ever, staring right at my face. Too embarrassed to meet her eyes, I whipped my head away.
"Lemme check... was it like this?"
Shlick shlick!
"Ugh?!"
The soft friction on my rigid shaft jolted me; I whipped back to stare at Seol-ha.
Pat-pat-pat-pat—
"Nghah...."
Intenser stimulation. A guttural groan slipped out.
"Ahaha! You are super turned on!"
Seol-ha sneered. Her slim, elegant hand squeezed tighter, stroking up and down relentlessly. Waves of electric pleasure crashed over me.
What she was doing? Straight-up handjob. Or in vulgar terms, jerking me off. Seol-ha was working my cock with gusto.
What the actual fuck was happening? Sexless virgin me—my brain kept fogging over. Felt unreal. Couldn't believe a knockout like Seol-ha was toying with my dick.
But.
Get it together, Do-yoon.
My head cleared fast. Feels amazing? Sure. But this was no good. She was just bullying me. No affection in that handjob. No lust for me. Met too recently for that shit. And I'm the nag tutor bugging her daily to study. A goddess like her into me?
Right.
This wasn't sweet. Just torment disguised as play. That thought chilled me out, restoring calm. Shake her off before it escalated.
"Teacher, you close already? Looks even bigger now."
Shlick shlick!
Pat-pat-pat-pat!
Even then, Seol-ha kept pumping away. Her pale palm glided over the ultra-sensitive glans, like a succubus squeezing out my load.
"No. Can't cum from this."
I choked back the moan to reply. Forced a chill expression—no way I'd let her look down on me. Not bluffing, either. The urge bubbled, but nowhere near climax.
"Really? Hmm...."
Seol-ha adorably cocked her head at my words. She'd been all expert bitch milking my glans for jolts of ecstasy moments ago; now she looked like a pure maiden. Trippy. For the girl who'd demanded my dick out of nowhere.
Whatever.
"Ah—yeah, got it."
Did she catch on? She'd been stroking the shaft thoughtfully, then pulled her hand away.
"No lube, right?"
Bingo. Beauty handjob's hot, but I'd cooled off composing myself. No direct lewd visuals? Still miles from busting.
"In that case...."
She paused mid-sentence with a sly grin. That smile oozed sex appeal—big trouble.
But what now? Gonna show porn?
I thought that—then froze.
"Hyup...."

Swish— Out of nowhere, Seol-ha stripped off her white tee. Her slim, toned belly gleamed smooth. The bra cradling her massive tits made its presence known.
This... is foul play.
Excitement choked my breath. Couldn't look away. No shot I'd manage it.
Twitch! Twitch!
Before I knew it, my cock throbbed harder than ever.
