Insatiable Night with the Instructor
“Hiiik! Heuk!”
Thwack! Thwack! Thwack! Thwack!
There was no holding back. In the position that let him plunge the deepest, he slammed his cock in to the hilt and pulled out, over and over. It wasn’t mere pistoning. On the thrust in, he angled deliberately to grind against her inner walls; on the pull out, he clenched the glans tight, raking her sensitive spots with intent.
Ugh… she’s so tight, feels like her pussy lips are gonna get dragged out…
Even with her juices soaking not just her but the entire bedsheet, the friction was intense. A cunt so perfectly fuckable he’d gladly pound it for life if he could.
“Again!… Cumming ag… Heuuek…!!♡”
“Kuh…”
Riiip… The blanket in Gwangnyeon’s grip tore a little. She’d ripped it without meaning to, her strength control lost to the overwhelming pleasure.
Riiiip… Squish…
To heighten her climax even more, he kept his cock buried and swirled his hips side to side, churning her depths. Less friction, more targeted stimulation of every nook and cranny. Intensely arousing for her with no real strain—making the orgasm hit that much harder.
“Feels good?”
“Huaa…! Go… good…! Hue… haa…♡”
Her dazed, honest reply to his hazy question was adorably endearing, sending delicious chills of mental ecstasy through him. No way this was the same cocky, untouchable woman from that morning.
Not just bodily bliss—the psychological thrill was soaring too. They weren’t in love, barely knew each other a few days, yet here they were, lost in mindless rutting… That fact alone made his spine tingle.
This was the illicit rush of a one-night stand. Men and women alike knew the judgmental stares society threw at it, but once you tasted it, stopping was impossible. He’d seen plenty of women like that. Though Gwangnyeon didn’t strike him as hooked—not yet, anyway. If anything, she seemed like it’d been ages since her last fuck.
Ages? No, wait…
Odd thought amid the heat, but she came off like a total newbie to casual hookups.
“Calmed down? Starting again?”
“Don’t… say sorry…”
Panting hard but clinging to her pride—cuteness overload. She’d switched to casual speech just thirty minutes back. Like her mind had been too fogged to stop it then; now, with the afterglow fading and senses returning, she was course-correcting.
Tongue still loose, though—speech all slurred.
“You like formal talk? Into younger guys?”
“Fuck off… what’s that got to… get lost… I prefer older… Heuk?”
Her mouth turning foul again. Easy fix: swivel the hips.
Squish… Squish…
Cock in motion, and she went quiet fast, breathy moans laced with sighs slipping out. When she craved his dick this much, shaking his hips felt like pure reward.
Can’t hold out anymore.
He’d endured plenty already. Hadn’t cum once.
“I’m hitting my limit too… Gonna go hard now, so hang in there?”
“Harder… haa… more than just now?…”
A slight nod answered her. Gwangnyeon’s eyes shifted—pleasure and unease mingling, but a flicker of anticipation too.
That look… and she claims to hate it rough?
Post-climax languor meant he’d started slow; now he ramped up. The back-and-forth pace quickened, turning ferocious in seconds.
Thwack! Thwack! Thwack! Thwack!
“Hiiik?! Wai… t…!! Mmph!!… Ummph!!… Mmph!!!”
Her cries louder than ever—loud enough to carry outside? She knew it too, clamping her mouth with her forearm to stifle the screams.
Already climaxed multiple times and burning hot, she was primed to tip over easy. Her pussy clenched and released in waves, telegraphing her peak.
Thwack! Thwack! Thwack!
Eyes fully dark-adapted, he took it all in. Sweat-slicked beauty biting back moans against the ecstasy. Breasts jiggling off-beat from the savage pounding, nipples stealing his gaze. Endless clear nectar foaming cheap white froth along his shaft from the friction. And those flawless pink inner lips splayed wide by his buried cock.
…Blood surged to his dick like never before.
“Gonna…!! Haa!! Cumming…! Mmph! Right now!!…”
“Me too… almost…”
“I’m cumming! Cumming nooow…!♡ *cough*! Heuk!!… Kek!!… Sto… p…♡ Kkheuk…!♡”
“Uuugh! So… fucking… tight… Kuh…”
Thwack! Thwack! Thwack!
Cock diamond-hard from the rush, pussy vise-gripping like it’d never let go. He ignored her nonstop orgasms, slamming away purely for his own bliss.
Too much—her drool trickled down her cheek.
He didn’t last. Ramming a climaxing cunt was pleasure beyond endurance.
Ugh… here… it… comes…!
Last shred of reason yanked his cock free. No birth control in this world—creampies were a no-go.
Spurt! Spuuuurt!! Drip-!
Uncommon volume splattered her pale skin. Forceful shots mostly hit upper chest.
But he had no bandwidth to notice. Mind-shattering ecstasy hijacked his brain, blanking thought.
Spuuuurt!
“Krrgh!…”
Cumming wouldn’t stop. Pent-up release crashed like a burst dam, whitening his mind. Soul-scouring clarity, like chugging industrial booze.
“Haak… Hek…”
“Huaa… Haa…”
Both lost in the fierce afterglow.
Whoa… now he saw: semen flecked her face and hair too. Shot far. White globs clinging to her orange bob—obscenely hot.
“Huaa… ha… what, didn’t cum inside? Was gonna boot your balls if you did…”
Shocked expression. Fair—rare for a guy to pull out unprompted mid-lust haze.
He just chased no-strings pleasure, but couldn’t say that.
Package it nice.
“I’ve always thought I had decent manners.”
“…”
What? No blowup?
Joking bait, but no snap-back. If anything, those eyes conceded the point.
…Weird thrill, getting props from Gwangnyeon.
Bit good, bit did she eat something funny?
Too stuck on her novel archetype?
She’d always been arrogant, rough, unbreakable. But tonight? Shy, subtly yielding.
If real… gotta watch assumptions with new faces. Could have hidden sides like hers.
“Ugh… beat… well, good romp. Satisfied? Then…”
“Satisfied? What’re you on about?”
He pointed to his still raging hard-on, glossy with her slick, showing zero signs of wilting despite the load.
“What?… Guys usually go soft after one, right…”
“Guess I’m the exception.”
“But I’m…”
“You came six times. I’ve only popped once—feels unfair, yeah?”
“…Not my fault…”
“Just two more. No holding back, so quicker than the first.”
One-and-done? Hell no. He stated his case firm. Minimum three to call it good.
Body had solid stamina—couple more no sweat. Natural Healing perk? Didn’t matter.
Eyes screaming no more give!, he pressed with conviction.
Gwangnyeon looked surprisingly fresh post-six. Superhuman endurance.
“Well… if you’re that insistent, maybe a little more…”
Her stunning red eyes flicked aside. Shy mumble trailed off faint.
Ears flushed pink.
…Really the same daytime hardass?
Gulp. Keep tempting him.
Words barely out, he guided her back down flat.
No begging permission—uncool. Smooth and sensible.
Hand gentle to her slightly dried pussy, caressing anew amid talk.
“Huu…♡”
The night of debauchery was far from over.
*
Click!
Window open, cool night air flooded in, shoving out the hours-old sex-heated fug.
Forest freshness hit, revealing the room’s lewd reek.
Ah… up again already…
Not just smell—traces littered everywhere. Prime exhibit: bedsheet drenched in sweat, juices, cum.
“No way you’re hard again?… Impressive on every level…”
“Haha… still young. Anyway, the sheets… what’s the plan?”
“…You wash ’em.”
“Me?”
“Then me? You’re trainee. I’m instructor. You know how it is.”
Pulling rank? His fault too, sure, but… why him over laundry staff?
Sigh… fair point, though…
Obscene stink from sweat and unspeakables—awkward handing off.
Anyone sharp sniffs from a meter out, knows the score.
Hand-wash only here; 99% busted.
Her job, long haul with coworkers. Rumors inevitable.
No dodging it. He rolled the sodden sheet tight.
“I’m showering—grab a fresh sheet from laundry, make the bed?”
“Blanket too? It’s torn.”
“Nah. I’ll stitch it later.”
“You… sew?”
“Why the fuck you complaining?”
Headshake. Why pissed post-fun? Complicated look.
“Something bug you?”
“…Nah, just hate your name.”
“Huh?”
“Drop Park Chanyoung. Till you slim down, you’re Pig. Digging fan? Wild Boar then. Yeah, Wild Boar.”
“…”
Pre-fuck she’d liked it. Hysteria relapse. This was his Gwangnyeon.
Cute and bashful? Myth.
Knock knock!
Sudden rap—jolted him like mid-felony bust.
Not cheating, no guilt… but who this late? Sex noise leaked? Noise complaint?
Ah! Right—novel extra chats her up at door tonight.
Likely him.
No sweat. Sense says hide duo in undies.
She’d fake sleep or ghost the knocks.
He’d play ghost too.
…Naive. He didn’t know Gwangnyeon yet.
“What?”
Creak…
Hold up! We’re in underwear…
Crazy! Answering like that?
Too sweaty for clothes, both in skivvies.
Door swings!…
“Uh… hi, Instructor?”
Knocker gawked at half-nude Gwangnyeon, froze, awkward wave.
Familiar mug. That meh-ugly face…
Blanc! Novel perv hitting on her was you?!
Blanc’s nameless extra—natural miss.
Flustered by her state, he peered inside.
Straight to him, dumbstruck.
“Trainee? The hell you doing here?”
“Uh… I… uh! Nothing! Sorry!”
Creak! Slam.
Blanc bolted downstairs.
Disaster loomed.
“What? Pervert?”
Blanc locked eyes with half-naked, bulging-pantied him.
Lewd-stinking room, scantily clad duo…
What’d anyone think?
Fucked.
“Ah… we’re toast…”
“Why? Know him?”
“My roommate… so, crashing here tonight.”
Bold claim. Declare beats ask—higher yes odds.
‘Sleepover okay?’ = 99% ‘Scram.’
Gwangnyeon gaped, absurd stare. Lunatic vibe.
“You lost it?”
“No, you flung the door—roomie saw. Back there? No sleep, day of hell. Own it.”
Full shameless mode. Innocent act, firm tone.
Bite?
“Sleep here? Cafeteria otherwise.”
“We fucked—bed-sharing’s fine.”
Middle finger salute. Dismissed.
Sober air, no sway. Missed that loose-tongued ‘feels good♡’ hour.
“How’m I supposed to show my face…”
“Not my problem. You’re gone in three months?”
“…”
“Kekeke! Free pussy? Take the L! Suffer~”
Grin blooming wide. Forehead-flick urge spiked.
Infuriating, but that smile was kinda cute—he’d let it slide this once.
