Sister-in-Law's Temptation
"Eunjeong... you've gotten so slutty."
"So you don't like it?"
Instead of answering, Taeseok pulled her by the waist and covered her mouth with his own.
Every time his tongue pushed familiarly through her mouth, Eunjeong's body gave a small tremor.
"Mmmnh..."
Slurp... suck... suck...
His hand slipped naturally under her skirt and stroked the sensitive flesh there.
"Haah~ Taeseok..."
Taeseok lightly lifted the moaning Eunjeong and set her on the dining table.
When the cold wooden surface met her hot thighs, she sucked in a short breath.
He gently spread her legs and pushed his body between them.
His fingers shoved her panties aside, revealing her plump, glistening pussy, already wet and shining.
"Haa..."
Eunjeong let out a low moan and clung tighter around his neck.
"You wore panties today."
"Yeah... because I like it when you take them off for me. And... I think you like taking them off me too..."
"Cute."
Taeseok pressed the hot head of his cock against her entrance and slowly pushed in.
No hesitation, no delay.
It was insertion as natural as a morning routine.
"Hwaaang~"
A moan like a scream burst from Eunjeong.
She took him every morning, yet the sensation still flooded her with tension every single time.
The moment his thick length forced her open and sank inside, her hips gave a little jolt.
"Ah... Taeseok... it feels so good. How is it... different every time?"
Her insides were hot and springy, wrapping tightly around him.
Taeseok gripped her waist firmly with both hands and drove himself all the way in.
Then he began to move—slow, but with a steady rhythm.
Thud.
Thud.
Every time the table shook, Eunjeong's full breasts swayed heavily inside her dress.
She buried her face against his shoulder and kept pouring out sweet, desperate moans.
Her legs locked around Taeseok's waist, pulling him deeper of her own accord.
"Taeseok... I love it... thank you so much..."
Still clinging to his neck, she breathed against his ear.
"Every morning... doing this for me... I want to engrave it every single day... that I'm yours. Haang~♡"
"Yeah... you're my woman. The one I want to fuck like this every day..."
The instant Taeseok lightly bit her ear and drove his hips harder, Eunjeong's body rocked hard.
And her eyes flicked toward the room where Eunsu was staying.
...Eunsu's probably already awake too.
The thought only made a strange heat surge through her around him.
She won't come out. Not while I'm doing this with Taeseok...
Eunjeong clenched hard around his cock.
She's listening to my moans, isn't she?
"Aaaang~ baby~"
Eunjeong made her voice a little louder.
I'm getting fucked by Taeseok like this, while all you can do is touch yourself. Fingers in your own pussy.
That fantasy made her even hotter and wetter.
That's right... listen. Your big sister... being held like this by Taeseok... you need to know it too.
Even though she was sharing Taeseok with her little sister, this short stretch of morning belonged to her alone—and she was proving it to her sister right now.
"Haaang... Taeseok... deeper..."
Eunjeong locked her legs tighter around his waist and rolled her hips herself.
Her pussy squeezed his cock hard; overflowing juices dripped one drop at a time down the edge of the table.
Right now... Taeseok is... only mine.
As if she wanted her sister to hear every word, she asked loudly,
"Haak~ Taeseok... do you like me? Doing it like this... with me... do you really like it?"
"Yeah... I really do. My Eunjeong... tastes so fucking good."
"Haaak~ I'm happy. That you think of me like that."
At last Taeseok slammed into her deepest point and poured a thick load of hot cum inside her.
Eunjeong's body shook hard as the wave of climax swallowed her whole.
She buried her face against his chest and whispered inward with a blissful sigh.
...Thank you. For making me... yours like this.
Still trembling, she clung tightly to him and savored the aftershocks of her orgasm.
After breakfast, Eunjeong got ready to go grocery shopping.
She put on a beige dress with good stretch.
It used to be just a comfortable everyday piece, but now it looked completely different.
The dress clung to her body.
Her breasts swelled and pulled the fabric taut; her waist nipped in to an extreme hourglass, and her hips rose full and round.
With every step the fabric over her thighs swayed softly, openly displaying every sensual curve.
Eunjeong checked herself once more in the mirror.
Same dress, completely different silhouette.
Almost too much...
But she didn't mind it.
She put on light makeup and left the house.
On the way to the nearby big supermarket, the air on the street had started to feel subtly different these days.
The reactions of people who passed her were clearly not what they used to be.
Blatant, lingering stares tracked her body.
A middle-aged man stood frozen with a cigarette between his lips, staring at her openly.
Two college students walking toward her stopped talking and turned their heads at the same time.
"...Whoa."
The soft murmur of admiration was definitely aimed at her.
Eunjeong heard it.
And she felt it.
She had become someone people looked at, someone people wanted to look at, someone men wanted to fuck.
Thud.
A passing man's shoulder brushed hers lightly.
"Ah, I'm sorry..."
He bowed his head in apology, but his eyes stayed somewhere else entirely.
On Eunjeong's chest.
And the curve that continued down past her waist.
For a second she held her breath.
"...It's fine."
She started walking again.
It had to have been deliberate.
Things like this happened often lately.
She straightened her back naturally and lifted her gaze.
As if she already knew she was the most eye-catching thing on this street.
She paused for a moment in front of the glass doors at the supermarket entrance.
Her reflection.
The sharply cinched waist.
The naturally swelling breasts.
The hip line that swayed softly with every step.
Eunjeong looked at that image for a moment, then smiled very small.
I should prepare something delicious again today... for Taeseok, who made me like this.
She headed for the meat section.
Something a little better, chosen with a little more care.
Things he would like.
Her walk carried far more ease and confidence than when she had arrived.
And that change only pulled the surrounding gazes even harder.
Then a KakaoTalk notification chimed.
Eunjeong stopped walking for a moment at the message.
Then, as if deciding, she sent her reply.
Around seven in the evening.
A luxury foreign sedan slid in quietly and parked in front of Eunjeong's house.
The door opened and a man stepped out.
Yoon Gicheol.
Eunsu's husband.
He wore a neat semi-formal look—no tie, the top buttons of his dress shirt loosened.
Tall, with a clean impression and sharp eyes.
His appearance was well-groomed, but his face was set hard.
Being summoned to the house of his soon-to-be-ex-wife's older sister was never going to feel welcome.
The moment Eunjeong heard the car from beyond the front door, she checked the mirror one more time.
Good enough.
She was wearing an ordinary dress.
The hem sat just below the knee.
Nothing flashy.
But the fabric still subtly outlined her figure, and the stretch made it easy to pull up or down.
It was clearly intentional.
"Welcome, brother-in-law."
Eunjeong opened the door with a smile.
Her voice was soft and gentle.
Gicheol paused for a second.
His wife's older sister.
They didn't see each other often, yet something about her felt unmistakably different from usual.
He couldn't name the feeling exactly, but the magnetic, attractive air around her was impossible to miss.
"Yes... it's been a while, sister-in-law."
"It has. Come in. I've been waiting."
Eunjeong stepped aside lightly; Gicheol entered the house.
His gaze lingered for a brief moment on the line of her waist before he looked away.
Too short an instant.
But Eunjeong didn't miss it.
Tonight she had to seduce him, and every little thing like that gave her courage.
A few days earlier, when Taeseok first suggested she seduce Eunsu's husband, Eunjeong had thought he was joking.
He wasn't.
When Taeseok laid out the detailed plan and asked for her agreement, she had nodded without a shred of resistance.
She was already that kind of woman.
Moving the way Taeseok wanted, acting the way Taeseok proposed.
It didn't feel strange or forced.
It felt natural.
What came after was worry.
The last time Taeseok had told her to sleep with another man, all she had to do was go along.
This time was different.
This time she had to make the first move and seduce him herself.
Would a man really fall for the advances of a thirty-nine-year-old woman?
But recent reactions had erased that doubt.
Her body changing every time she looked in the mirror.
The stares on the street.
And just now, the way Gicheol had looked at her.
That was enough.
They sat facing each other on the sofa.
"So... what did you want to talk about, sister-in-law?"
"Honestly... I was pretty shocked when I heard from Eunsu. About the divorce..."
Eunjeong slowly tucked her hair behind her ear.
The line of her neck appeared.
The thin collarbones below it.
A calculated little motion so his eyes would naturally drift that way.
"Did she... tell you why things got to that point?"
"Yeah. Not everything, but... the gist. Our Eunsu has always been a bit free-spirited."
Eunjeong looked at him.
Her eyes held pity.
"Sister-in-law... it's not something you can just brush past like that. Do you have any idea how much I've put up with?"
"I'm sure you have... I understand. But... what if the two of you tried again?"
"Our marriage is already over. If that's what you called me here for... I'll be going."
Gicheol stood up from his seat.
"Still... you came all this way... leaving like this would hurt my feelings..."
Eunjeong's voice dropped lower.
She didn't stand.
She kept her legs together, tilted slightly to the side, and only lifted her head to look up at him.
Fuck... why does my sister-in-law look this hot today?
Gicheol's feet stopped.
"You used to treat me really well, you know."
She spoke slowly.
"Trying to look good for Eunsu... asking me all sorts of things, buying me drinks."
As if remembering those days, a faint smile touched her lips.
At her words, Gicheol's eyes wavered for a moment.
"Don't bring up embarrassing old stories..."
Embarrassment and the look of a man trying hard to ignore something flickered across his face in turn.
Eunjeong rose slowly and stood right in front of him.
Close enough that her breasts almost brushed his chest.
She tilted her chin up slightly to meet his eyes.
"Back then, Gicheol... you liked me quite a bit. If you hadn't, you wouldn't have helped things go well with my little sister."
"The situation's changed a lot."
"Every time Eunsu dumped you, I bought you drinks... during the dating, during the fights..."
"Yeah. I really... owe you a lot of gratitude and apologies. Still..."
"How about a drink tonight too?"
Eunjeong cut him off and lightly brushed his wrist.
Gicheol fell silent for a moment.
His gaze wavered.
There was no reason to drink with her, yet somehow he couldn't refuse.
In the end he let out a small sigh.
"...Just one glass."
Eunjeong smiled brightly at those words.
She led him back to the sofa.
This time not across from her, but right beside her.
"Okay. Just one glass."
