My First Fellatio♥
The air in the room grew thick and sticky.
Layered over the musty scent of old paperbacks on the bookshelf...
It was because the hot heat radiating from Woohee noona's body and mine was clinging together, sticky, sticky.
Before I knew it, the front of my pants was stretched taut, forming a tent on the verge of bursting.

"Haa... haa......"
Woohee noona sat on the edge of the bed, unable to tear her eyes from my swollen lower half, breathing raggedly.
"N-Noona...... Don't stare so intently..."
I hurriedly twisted my body to hide my crotch.
"Stay still."
Woohee noona's pale, slender hand sliced through the air and clamped down over the bulging outline on my pants.
I flinched!
"Hng...!"
The moment her cool palm touched me through the fabric, a sharp thrill shot up my spine.
Woohee noona's hand was visibly trembling.
"It's hot......"
Noona murmured in a cracked voice.
She slowly applied pressure with her palm over my pants, carefully tracing the shape of the stiff pillar hidden inside.
Like a tamer approaching a massive beast for the first time, her touch was clumsy, half curiosity, half fear.
"N-Noona. Are you really... really going all the way? What about Haru noona...... I want to do it with Haru noona."
I gasped, clutching the mattress tightly with both hands.
But instead of answering, Woohee noona brushed back her sweat-dampened bangs and looked up at me.
Her usually porcelain-pale face was flushed beet red from her nape to her ears.
"Haru unnie... will already think we've crossed the line."
Noona's fingers fumbled with the buckle of my belt.
"And you're excited too."
"...This is just a physiological reaction. I like Haru noona."
"No excuses."
Click, ziiiip.
The sharp sound of my belt buckle unfastening and zipper descending cut through the room.
I sucked in a sharp breath.
"Your body proves it. Your instincts want me. You know? As long as we don't copulate, it's not cheating. I read that perspective in a book."
Woohee noona tried to justify the situation with logic from a book, but her trembling voice and heaving chest revealed she was utterly overwhelmed too.
Noona wanted me.
The plan to make Haru unnie jealous had long lost its pretext and evaporated.
Woohee noona gripped the waistband of my pants with both hands and yanked them down to my knees along with my underwear.
Whoosh—!
Freed from the confining fabric, my cock sprang up heavily, revealing itself in the air.
"Ah......"
Woohee noona's lips parted unwittingly.
She covered her mouth with one hand, staring down at my raw, exposed flesh in disbelief.
It was overwhelmingly real compared to the precise anatomical diagrams in the Human Reproduction and Reproductive Biology book from the underground storage.
The difference between 2D and 4D, I suppose.
Veins bulging ruggedly along the shaft, subtle throbbing with each ragged breath,
And at the tip, thick, viscous precum beading and dripping transparently.
"The smell......"
Woohee noona wrinkled her nose with a groan.
"The diagrams... didn't mention this fishy, intense scent."
Noona seemed a bit embarrassed now that she was seeing a real cock, her eyes watering red, but...
She couldn't tear her gaze away.
Like a scholar exploring new knowledge,
Or a female animal unable to suppress her hunger,
Her sticky gaze dissected every inch of my genitals.
I had to endure the cold sweat trickling down my back, my most private and filthy part laid bare before her eyes.
"N-Noona... stop looking... please give my clothes back......"
Unable to bear the shame, I twisted my hips to pull up my pants.
Smack!
But Woohee noona firmly swatted my wrist away and wrapped her thin, cool hands carefully around both sides of my hot shaft.
"Hngh...!"
The destructive stimulation from the temperature difference made my hips buck reflexively.
Woohee noona flinched at the feel of the hot mucosa too, but she didn't let go.
Noona swallowed hard once, then slowly leaned her upper body forward, bringing her face toward my crotch.
"N-Noona? Wait... you don't mean you're going to......"
I couldn't believe my eyes.
Woohee noona, the greenhouse's intellectual boasting the coldest reason, was kneeling between my legs with her lips parted.
"In the book... it said this. The act I'm about to do is called fellatio, shortened to felatio."
Noona's lips hovered at a tantalizing distance from the glans, almost but not quite touching.
'My cock itches—'
Her hot, moist breath tickled the sensitive mucosa, making my lower belly churn wildly.
"For successful copulation... mucosa must exchange with mucosa through sufficient foreplay. To maximize the male's arousal... reduces failure probability."
Logical rationalization.
To hide her bursting lust and shame, noona used Mama's command and book knowledge as a shield.
But such flimsy excuses didn't matter.
What mattered was that she was about to take me in her mouth.
"Haa... I'll, I'll check it. How effective this physical stimulation is... Hng♥ It'll be enough practice for when you do it with Haru noona someday."
Woohee noona squeezed her trembling eyelids shut.
Then her small lips parted slowly, and the tip of her tongue flicked up the beaded precum.

Lick—
"Haa...."
A deep sigh escaped my lips.
I could only clutch the thin straps of Woohee noona's slip tightly with both hands.
Woohee noona shuddered at the first taste of male fluid and its distinctive fishy scent.
Her tongue instinctively recoiled, but she gathered courage and didn't back down.
"Hng... hngh......"
Woohee noona opened her lips wide again, this time taking half the glans into her mouth at once.
Slurp, slurrp♥
"Haaa... N-Noona... Ngh, Woohee noona......!"
What is this...
What the hell is this...... Slippery and soft and warm tickling my cock...
The hot, slick oral mucosa enveloped and squeezed my swollen shaft.
A level of pleasure worlds apart from Jiha's clumsy handjob.
A woman's mouth—a perfectly hot, wet chamber—was devouring my cock.
But Woohee noona's fellatio was terribly unskilled too.
"Ah, it hurts noona! Teeth, your teeth are scraping......"
I groaned in a mix of pain and pleasure, and Woohee noona startled, pulling her mouth off.
Pop♥
Sticky saliva stretched long from the shaft and dripped.
"S-Sorry."
Woohee noona wiped her wet lips with her hand and apologized.
"It's... bigger than I thought, so trying to cover it just with my lips keeps scraping on my teeth. My jaw hurts too."
She grumbled like someone stuck on a tough logic puzzle, but her gaze stayed glued to my reddened shaft.
"Then don't do it... Haa, you don't have to, so stop...... We'll get in big trouble like this......"
"Who said stop."
Woohee noona cut me off sharply.
"Quitting halfway through something I've started isn't my style. I just need to open wider."
Woohee noona puffed her cheeks with determination and opened her mouth wide again.
She gripped the base firmly with both hands for support, then lowered her head to take me in once more.
Sluuuurp, smooch♥
"Haa, haa... Hngh, this is driving me insane......"
This time, noona tucked her lips inward to avoid her teeth, carefully bobbing her head up and down.
Each time her warm, soft oral mucosa glided over the glans's contours, my hips kept bucking into the air uncontrollably.
And that wasn't all.
Woohee noona's silver hair cascaded over my thighs and pubis, delivering a pleasant itchiness.
With her mouth full, she furrowed her brow as if her jaw ached, but she tried to curl her tongue around the shaft and lick upward.
Slurrp, smooch... suuuuck—♥
The quiet room filled only with the creak of bedsprings and lewd, wet friction sounds.
Mmm... smooch, slurp......♥

Woohee noona's nasal hums tickled between my legs.
"Hah... hah...♥"
Noona occasionally pulled off to gasp for air, saliva droplets glistening and trailing down my shaft each time.
Her messy, amateurish efforts were perfectly vaporizing my sanity.
"Haa... Woohee noona, I, I'm gonna come. Wait, it's dirty stuff—"
The overwhelming ejaculation pressure boiling from my lower belly made me shove at her shoulders urgently.
But Woohee noona clamped my thighs with both hands, shook her head, and tightened the suction in her mouth even more.
Suuuuuck—♥
"Haaa...! N-Noonaaa!"
I couldn't hold it.
In the end, I unleashed my lust completely deep into Woohee noona's hot mouth.
Splurt— spluuurt—♥
"Mmph...♥ Mmm♥"

Woohee noona's throat bobbed heavily once.
Startled by the flood of hot, fishy semen, she squeezed her eyes shut but kept her lips sealed, taking it all.
Each pulse and contraction of my cock was gently milked by her oral mucosa, squeezing out the last of the pleasure.
"Haa... haa......"
Feeling my vision flicker white, I collapsed onto the bed.
My head spun as if all oxygen had drained from my brain, my whole body trembling uncontrollably.
Pop♥
Woohee noona slowly released her lips and straightened up.
Undigested milky fluid clung stickily to the corner of her mouth, precariously trailing down her chin.
Woohee noona roughly wiped her mouth with the back of her hand, panting heavily.
Her teary eyes stared down at me blankly.
"Haa... haa... This is......"
"This... is a man's... semen."
"Noona..."
"Ah... Every breath, the fishy smell from inside...♥"
Woohee noona stared blankly at the semen on her hand, then buried her face in both palms and slumped forward onto her knees.
