Sex with Iseol Noona
At the order to undress, Iseol noona's shoulders flinched and trembled.
She couldn't lift her head. Instead she fidgeted, stalling.
The alluring woman from a moment ago vanished, and suddenly she started rattling off excuses in the polite speech of a teacher.
"I-I'm a... I'm a teacher, and Sihyuk, you're, well, you're an adult, but..."
Her voice dwindled to nothing. The way she panicked, completely at a loss, was honestly pretty cute.
"And I've never done anything like this before... Plus you're so popular, and there are so many pretty girls around you. Chaerin, Subin... Why would you even want me..."
She kept babbling on and on.
But nowhere in any of it was a real refusal. There was no "I don't want to."
It was just the pure fluster of a virgin thrown into a situation she had never faced in her life.
I tightened the arm around her waist and pulled her flush against me.
My rock-hard cock pressed firmly against her lower belly.
"Ah...!"
Iseol noona let out a short gasp and looked up at me.
I leaned in to her ear and cut through every last excuse with a single line.
"You want to have sex with me, don't you?"
"..."
Silence hung in the air.
Instead of answering, Iseol noona only worked her lips soundlessly.
Then, a moment later, as if resigning herself—or as if she had been waiting for this—she gave a tiny nod.
"...I want to."
It was barely louder than a mosquito, but the affirmation was clear.
"Then it's okay if we have sex, right?"
"Yes..."
With that, she abandoned all resistance.
The instant I heard her answer, I sought her lips again.
This time was different. I brushed my mouth softly against hers first, then carefully pushed my tongue inside.
"Mmnh..."
Her lips parted in surprise.
I didn't miss the opening. My tongue slid right in.
A wet little sound.
Halfway in, it met her warm, soft tongue.
I didn't really know how to kiss either, and for her this kind of deep kiss was a first.
Still, I took the lead and licked at her with my tongue.
Who would have thought I'd be sharing a deep kiss like something out of a drama with my homeroom teacher.
At first her tongue stayed stiff and frozen, not knowing what to do, but when I gently wrapped around it and coaxed it, she began to respond carefully.
Our tongues tangled. Saliva mixed.
The lewd sounds of us devouring each other's mouths echoed strangely in the quiet sexual-processing room.
Kissing feels good.
So this was a real kiss.
Mixing tongues with a woman was this insanely arousing?
When the long kiss finally ended, a long, transparent strand of saliva stretched between us.
Iseol noona's eyes were wet and completely unfocused.
The rational teacher from earlier was nowhere to be found. What I saw now was simply a woman surrendered to desire.
I slowly undid the buttons of her blouse one by one.
First button, second... With each one that came free, pale skin and a plain gray bra gradually appeared.
Not a single ounce of excess fat, smooth skin that still kept a woman's soft curves.
The breasts swelling high above the bra looked ready to burst free any second.
I almost failed to get the bra off because I didn't know how the clasp worked.
Next were her dress pants.
When I lowered the zipper, her body trembled faintly with shame. I paid it no mind and stripped the pants down.
White thighs appeared, along with gray panties that matched the bra.
I couldn't tear my eyes from those plain gray panties.
The center was already a little damp.
She must have been leaking love juice the whole time we kissed, unable to hold it back.
That fact only made me harder.
"Teacher."
When I called her softly, she lifted her head.
"You're soaking wet."
Her face flushed crimson again and she dropped her gaze once more.
Smiling, I pulled her panties down too.
And at last, Iseol noona's completely naked body was laid bare before me. I guided her to the bed.
I laid her down, stripped myself, and climbed on top of her. My heart hammered like mad.

Calm down. Kim Sihyuk, calm the fuck down.
I was so worked up I might miss the hole entirely and just come all over her thigh.
I took deep breaths, trying to force the excitement down.
Iseol noona kept her eyes squeezed shut, breathing hard and fast.
Her flushed face, slightly parted lips, the full breasts rising and falling with every breath, even the small patch of pubic hair lightly matted with love juice—
Every single detail looked like a work of art.
Looking at that erotic sight, there was no way the heat was going to settle.
I settled between her legs.
Finally my cock and her pussy faced each other.
My fully erect cock was already drooling precum, desperate to get inside her.
Her pussy glistened with so much wetness it looked like it would take me easily.
But the moment I actually pressed the head against her, the entrance was far tighter than I expected.
"Hngh..."
When the head touched her entrance, she held her breath. I swallowed hard with nerves myself.
My cock was pretty big. Could something like this even fit inside a virgin like her?
I gripped her waist and pushed my hips forward slowly—very, very slowly.
Even soaked, it was a tight, resistant feeling. The sensation of my cock forcing its way into her pussy.
"Ah...!"
As the head popped inside, a moan mixed with pain tore from Iseol noona's lips.
I stopped moving and waited for her to adjust.
"You okay?"
"Y-yeah..."
She nodded. Her pussy didn't reject me.
If anything, the inner walls twitched as if they wanted to take more of me, gently biting down on my cockhead.
That tiny movement made me want to start thrusting wildly. I barely held back and savored her virgin pussy.
So this is a pussy. Holy shit...
At first the tension made it feel a little stiff, but when I stayed still it turned soft.
Then came the heat.
I couldn't wait any longer. I shoved the rest of my shaft in.
A wet, meaty sound.
"Hyaang...!"
At last my cock was buried inside her.
I was too big to get the root all the way in, but her pussy was stuffed full of me.
A massive wave of pleasure ripped through my whole body.
That packed fullness. Hot, soft, tight, wet flesh wrapping every inch of me without a single gap.
Pleasure I had never even imagined before.
In my past life I never even held a girl's hand, and now I was inside a beautiful noona like this—because she wanted it.
The sheer mental satisfaction alone almost made me come.
I began moving my hips slowly.
At first I was clumsy. Not knowing how to thrust, I rocked my whole upper body with it.
I just swung my hips back and forth on pure instinct, chasing bigger pleasure.
But even that felt incredible.
And the woman under me was feeling even more of it than I was.
"Hah, nngh, ah...!"
I had no idea what getting speared by a thick cock felt like for a woman, but her expression was already lost in pleasure.
I hadn't even thrust many times, and already the urge to come was climbing hard.
At this rate I wouldn't last a minute.
Fuck!
Maybe it was because it was my first time and we were going bareback without a condom.
Having sex with a woman this gorgeous, of course I wouldn't last long.
Right as I was panicking over what to do—
"H-hngh, haaaang!"
Suddenly Iseol noona arched her back and let out a high scream.
At the same time her pussy convulsed, clamping down hard around my cock.
"Ugh!"
The crushing pressure forced a sharp breath out of me.
I almost blew my load right then.
I had barely even started pumping and she came first.
Her whole body shuddered through an orgasm she was feeling for the first time on a cock.
The sight was so filthy I nearly came inside her on the spot.
"W-wait... Sihyuk... just a second..."
She gasped for air in the aftershocks, begging, but I couldn't stop. No—I had no intention of stopping.
Her climax only poured gasoline on my fire.
Just like I'd seen in porn, I hooked her legs over my shoulders and started slamming my cock down into her pussy.
"Ah! Hngh! Hahng! W-wait, I'm still...!"
Wet, filthy slapping sounds filled the room.
After a few thrusts I started getting the hang of it.
My body learned how to lock my upper half in place and piston deep and hard using only my hips.
The better my technique got, the louder her moans became.
"Hngh, ah, ah! I don't know this, it's too deep...! Aaang!"
The amount of love juice pouring from her pussy kept increasing.
There was no tightness left at all now.
Every time my cock scraped along her walls, sticky juices squelched and sprayed everywhere.
"N-nngh! I'm gonna come again! Sihyuk, ah, I can't...!"
A woman's moans at the peak of orgasm were the best thing in the world.
A sudden spray.
Shuddering as she came, she squirted a short jet of fluid.
The look she gave me while biting her lip hard was pure submission.
Hearing her climax voice sent the urge to come roaring all the way to the top of my skull again.
Shit. This won't do. I want to fuck her longer without coming yet.
To give my cock a short break, I spoke.
"Noona."
"Hngh... yes...?"
"You're so beautiful."
"A-aah... th-thank... you..."
She tried to turn her head, embarrassed that she was moaning while getting fucked by a younger man.
So I deliberately caught her face, forced our eyes to meet, and said it sweetly.
"You're cute."
"Hnn..."
I flicked my hips slowly again.
When the head prodded her cervix, she panted out hot breaths.
"From now on, when it's just the two of us, I'll call you noona instead of teacher."
"Y-yes...! Ah, wait...!"
"You have to answer, Iseol noona."
"Yeees... I-I like it..."
I pounded into her pussy while raining praise on her.
Even while losing her mind to pleasure, she struggled desperately to answer. It was adorable.
Then the most important words suddenly came to me.
"Noona."
"Haang...?"
"I'm gonna come inside."
At that, Iseol noona's body jerked hard. She couldn't speak.
She just nodded frantically while letting out even more lewd moans.
Her pussy clamped down on me again, hard.
"Haaaang! I'm, I'm coming...!"
The moment she reached the peak of another orgasm, I couldn't hold back either.
"Coming...!"
I gripped her waist and began pouring hot cum into the deepest part of her pussy.
Thick pulses. More and more.
Even while ejaculating I never stopped moving my hips.
"Huuuh...!"
Mind-breaking pleasure.
Nothing I had ever felt in my life compared to this.
The more I ground my spurting cock inside her, the more the ecstasy multiplied.
I mercilessly slammed my hypersensitive cockhead against her soft inner flesh while still coming.
Everything was perfect. It felt like I had been born for this exact moment.
Even after I finished, I left my cock buried inside her for a long time.
Breathing hard, I savored every last aftershock of my first time.
