24. You Have to Use Contraception.
Episode 24. We Need Protection
White fireworks exploded one after another in Na-eun's mind. Every time Jin-hyuk's thick fingers roughly scraped along her vaginal walls, the pleasure surging from below threatened to melt her consciousness away.
Without realizing it, Na-eun clenched her buttocks tightly. Her pussy continuously squeezed and bit down on Jin-hyuk's fingers as they pushed deeper inside, clinging to them desperately.
"Hng... Hah—ah!"
Senseless moans spilled from her lips without pause—no different from the cries of a beast that had been held back for too long.
The face she had carefully adorned to look pretty was now helplessly contorted in pleasure. Her unfocused eyes rolled back halfway, and her red tongue lolled out between parted lips as she panted roughly. Even in this disheveled, ruined state, an intoxicating allure dripped from her, only further stoking the man's arousal.
Jin-hyuk's lower half had already reached its limit. His thick, swollen cock, straining to the point of bursting, oozed sticky pre-cum from its tip as if demanding to plunge into Na-eun's pussy right that instant.
This was on an entirely different level from the clumsy pleasure she had experienced alone in her room.
A space where no one could hear them, no matter how loudly she screamed.
Na-eun cast aside even the thinnest shred of shame. She writhed wildly, surrendering her entire body to the waves of pleasure Jin-hyuk created for her.
Squelch, squish.
Every time Jin-hyuk pulled his fingers out, Na-eun's pink pussy flesh clung to them wetly. The relentless scraping against her delicate inner walls had turned her arousal fluid cloudy, dripping thickly down her thighs and soaking the sheets beneath her.
With a final forceful thrust, Jin-hyuk abruptly yanked his fingers free.
Pop!
"Ah—ahhh!"
The moment his fingers slipped out, Na-eun's back arched violently off the bed.
Splurt!
A gush of sticky fluid splattered everywhere from her gaping entrance. Her entire body trembled as if seized by a spasm, her fingers clawing at the sheets.

"Haa... Hah... Haa..."
Gasping for air, Na-eun barely managed to gather her scattered focus. Jin-hyuk's sweat-slicked form came into view. Despite having just been wrung dry by overwhelming pleasure, the emptiness inside her now felt unbearably itchy.
Thirst.
A vast, aching void.
She didn't just want fingers—she craved something far thicker, far hotter, something that would ruthlessly pierce and scrape her insides. The hollowness in her belly was maddening.
Jin-hyuk sat up on the bed, roughly tossing aside the towel that had barely clung to his waist.
"Hahk—"
Na-eun's breath hitched.
A massive pillar filled her vision.
It was even bigger than she had imagined. The engorged, reddened flesh pulsed visibly, its veins bulging as it twitched with every heartbeat. Her brain struggled to process the fact that something so monstrously huge was about to push inside her.
"O... Oppa."
Na-eun's shoulders hunched instinctively. Sensing her fear, Jin-hyuk paused.
"Na-eun."
His voice was thick with concern. Despite the feverish desire burning in him, he held back, refusing to force himself on her.
Na-eun stared up at him with damp eyes, licking her lips before swallowing hard. Though she was terrified of being torn apart, she wanted to give herself to him completely. She had no intention of backing down now.
"I... I can take it."
She spoke firmly, as if making a vow. Jin-hyuk moved between her legs, his heavy presence pressing against her. The pre-cum beading at his tip smeared against her slick entrance.

"W-We... need protection," Na-eun whispered urgently.
Jin-hyuk froze mid-motion, momentarily thrown by her request.
(He had never used condoms with Eun-joo.)
"In my bag... I packed some."
With trembling fingers, she pointed to her bag on the floor. Jin-hyuk unzipped it and pulled out a foil packet.
Riiip.
The sound of tearing plastic.
The thin condom was rolled over his swollen, reddened cock, the transparent latex tightly sheathing his veined length. Once secured, Jin-hyuk positioned himself between her thighs again.
The condom-covered tip pressed against her dripping entrance.
With a slow, deliberate push, Jin-hyuk's hips began to advance.
Schlllp... Schllp.
The heat of his flesh, combined with the unfamiliar friction of latex, scraped against her sensitive walls. The massive pillar forced its way in mercilessly, stretching her tight passage wide.
It was hot.
She marveled at how a human body could radiate such scorching heat. Na-eun stiffened as the heavy weight pressed against her entrance, her entire body locking up. When the swollen tip pressed against her delicate folds, it burned like a brand.
Her consciousness shattered.
Fear.
Curiosity.
Could something so enormous really fit inside her? Could she take him without being torn apart? Her chest heaved with ragged breaths.
"I'm going deeper."
Jin-hyuk's low voice reached her ears. Na-eun squeezed her eyes shut and wrapped her arms tightly around his neck.
"Hold me."
At her plea, Jin-hyuk's strong arms enveloped her trembling back, pulling her close. At the same time, a sharp pain surged through her.
The thick tip forced its way past her tight entrance, ruthlessly parting her delicate flesh. It felt like her body was being split in half.
"Hng—uhhp!"
Jin-hyuk crushed his lips against hers, swallowing her scream.
Schlurp, schllp.
Their tongues tangled wetly. Na-eun desperately sucked on his invading muscle, swallowing his scent as she struggled to suppress the agony in her lower half.
Her breath grew ragged.
His thick length pressed forward relentlessly, stretching her narrow walls to their limit. The sensation of her inner flesh being forcibly expanded sent shivers up her spine.
Jin-hyuk paused, panting heavily, giving Na-eun time to adjust. She rested her sweaty forehead against his cheek and whispered into his ear.
"Haa... Do it... Fill me up."
Her breathless plea. She needed to take all of him inside. She was determined to shed the label of being just a cute little sister—she wanted to brand herself into his mind as a woman.
A possessive desire to claim him with her tight, scorching walls.
A desperate instinct to bind him to her forever by giving him her first time.
So he could never leave her.

"Hnnng—uhhh!"
Jin-hyuk's massive cock plunged deeper, splitting her apart. The sheer bulk of him was incomparable to the fingers that had teased her earlier.
There was no space left—only overwhelming pressure as he filled her completely. The sensation of her insides being rearranged dominated her entire body.
The rough scraping against her delicate flesh.
Na-eun's back arched off the bed, her knees locking around his waist in a primal mating reflex—her body instinctively pulling him deeper.
Deeper.
To the very core of her.
Finally, the swollen tip pressed firmly against her sealed cervix.
"Haa... Ah—!"
The impact sent a jolt up her spine, straight to the crown of her head. The pain and pressure transformed in an instant, detonating the suppressed pleasure into an explosion of sensation.
White-hot ecstasy flashed through her mind. The agony of being split apart had morphed into a searing, electric pleasure that clawed at her belly.
"Ah... Ahh...!"
Fat tears spilled from Na-eun's eyes, dampening the sheets. Overwhelming joy—she had taken him all. The most primal pleasure a woman's body could experience.
Clutching Jin-hyuk's broad back as if she might break, she let out a shuddering moan.
"Hng... Uhh..."
As the floating sensation began to fade, Jin-hyuk's cock slid out slightly. Her sticky walls clung to him, stretching wetly.
Then, with a single thrust, he buried himself inside again.
"Haa—ahh!"
A broken cry tore from Na-eun's lips.

His engorged length began moving in earnest, pistoning in and out of her with deep, deliberate strokes.
Schllp, schllp, schllp!
"Haa... Haa..."
Jin-hyuk's breathing grew rougher, his pace quickening.
"Ahh... Uhh!"
Suddenly, he pulled her close, whispering urgently.
"I'm gonna cum."
"Y... Yeah."
Na-eun nodded frantically.
Thrust!
"Hnnng—uhhh!"
His cock buried itself to the hilt, slamming against her cervix. Her stretched walls convulsed, splattering fluid everywhere as her entire body trembled like she'd been electrocuted.
Pulse, pulse.
His veined shaft throbbed violently. Thick, hot cum spurted into the condom, battering her entrance with each jet. The thin barrier denied her the scalding heat of his seed directly against her walls, and her cervix clenched around him in frustrated desperation.
"Ahh... Aaahh!"
Na-eun collapsed completely under the tidal wave of her orgasm.
"Haa... Haa..."
Jin-hyuk's ragged breathing gradually steadied. Na-eun blinked away the haze in her vision, slowly regaining her senses.
"O... Oppa."
Jin-hyuk brushed her sweaty bangs aside and murmured,
"You did well."
"No... It was amazing."
Her voice was hoarse. She had been too overwhelmed just taking him in—she hadn't done anything for him. A pang of guilt struck her. Jin-hyuk silently stroked her damp hair.
Schllp.
"Haa... Uhh..."
His swollen cock slowly pulled free. As the pressure eased, her inner walls twitched with aftershocks.
The condom, now heavy with his release, was streaked with vivid red—her maidenhead blood.
"Ah..."
Hot tears welled in Na-eun's eyes again.
Jin-hyuk removed the condom, tied it off, and tossed it into the trash. Yet despite being freed, his cock remained stiff and throbbing.
Na-eun's heart sank. While she had been lost in pleasure, he hadn't found release. She wanted to satisfy him, but she didn't have the strength to move a single finger.
"It's fine. We can do more next time."
Jin-hyuk wrapped an arm around her bare shoulders. Na-eun nestled into his embrace and whispered,
"Thank you."
