35. Sister-in-law Da-hye, Who Got NTR'd(?) by Her Older Sister and Enjoys Defeat Masturbation Beside Them. 'What is this feeling...? My chest hurts with a stinging sensation, and yet... something... I mean, something...'

Seo Da-hye, who had been NTR'd(?) by her older sister, experienced something beyond just the hollow ache in her chest. 'Pleas... pleasure...?'

It was a perverse excitement born from defeat. 'I-I'm wet...'

For the upright and proper virgin Seo Da-hye, this was an emotion far too difficult to comprehend. But she wasn't even given the time to deny it—before she knew it, she could already feel the dampness soaking through her panties. 'This shouldn't be happening... T-this can't be right...'

Sssss...! Her rationality screamed that this was wrong,

But her instincts, already swept up in the moment, compelled the defeated female Seo Da-hye to let her hand drift downward. "Kuuuuh...! Our Mi-na's pussy... such a fucking delicious cunt..."

Squelch...! ♡ Glorp...! ♡ Schlick...! Squelch...! ♡

"Hnnngh...! Hahhht! Hnnngh...! ♡ I love you, you fucking bastard... Hnnngggh! ♡ Hnnnngh...!"

'Khhh... Khhhh... I shouldn't... Hnnngh...'

Squish...! Squelch...! Squish...! Seo Da-hye's fingers, clumsy and uncertain, slipped not over her clothes but beneath her pure white panties—right into the soaked folds of their owner. Those fingers moved in time with the sounds of her older sister and ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠brother-in-law fucking in the next room, stimulating her pussy to draw out pleasure. "Kkkk...! Can't you see my cock sliding in and out like this, Mi-na...? Don't turn your face away—look at it..."

Plunge...! ! ♡ Squelch...! ! Schlick...! ! Plorp...! ! ♡ Glorp...! ! ♡

"J-just fuck me deep alreadyyy—Khhhhnngh! Hngh! Hnnngh! With that long, thick thing! Hnnngh! All the way inside me! Hnnnngh! Deep, deep inside! Hnnnngh!"

"Our Mi-na really is so shy, huh..."

The defeated masturbator Seo Da-hye's plaything,

Geum Tae-yang slowly, deliberately thrusted in a one-leg-up standing side-fuck, his cock plunging deep as he wrapped his arms around Seo Mi-na. It was an invitation to enjoy the spectacle of their coupling together. But Seo Mi-na, her face flushed red, averted her gaze and snapped at him with a sharp edge to her voice. Despite having fucked Geum Tae-yang hundreds of times, this pure-hearted female still couldn't bear to watch his cock sliding in and out of her pussy. "This is why I'm crazy about you, Mi-na... How the hell could I not lose my mind over you...? Acting all tough, but melting more than anyone else for the man you love... That's the kind of ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠lover you are..."

Squeeze...! ♡ Squeeze...! ♡ Squeeze...! ♡

"Hhaaahhhngh...! ! God, you talk too much, you fucking dickhead...! ♡ Haaahhhngh...! Hngh! You're so full of yourself just because you took my virginityyy...! ♡ Hiiiiih...! Hhaaahhhngh...! ♡"

Rock...! ! ♡ Twist...! ! ♡ Rock...! ! Slurp...! ♡ Slurp...! Rock...! ! ♡

Geum Tae-yang groped Seo Mi-na's ample 75G breasts with abandon, attacking her in another way. Where was his target? Perhaps the soft, vulnerable flesh hidden beneath her thick turtle-like shell? When Geum Tae-yang, who knew her true self, pointed it out, Seo Mi-na felt both embarrassed and happy. And so, she swayed her hips seductively, loving both her future husband's cock and his heart. "Who took this pussy's virginity...? Who tore this pussy's hymen apart...? Say it, come onnn!"

Plunge—squelch! ♡ Squelch—schlorp! Plunge—squelch! ♡ Squelch—schlorp! ♡ Plunge—squelch! ♡

"Hahht! Hnnngh! You diddd! Hnngh! You fucking dickhead, Geum Tae-yang! Hngh! Haaahhhngh! With this thick, long thing! Hnnngh! Hngh! You turned me into a deflowered, slutty female, didn't youuu! Hhaaahhhngh! Hahht!"

Rock—rock! ♡ Thrust—rock! ♡ Rock—rock! Sway—sway! Sway—sway! ♡ Thrust—rock! Rock—rock! ♡

A bond that not even a split sky could change,

Geum Tae-yang had taken Seo Mi-na's virginity. By reminding her of that, he relentlessly attacked the proud Seo Mi-na's vulnerable inner self. The wide, full-thrusting strokes of his cock were almost secondary. 'B-brother-in-law's thing...! So roughhh...! Hnnngh...!'

Squish! Squelch!

Squelch! Squelch! Seo Da-hye could feel the rough thrusts of her brother-in-law's cock and the relentless pounding growing even more savage. Naturally, her own defeated fingers mimicked the rhythm, shifting into a fierce tempo of their own.

"Hah—! I'm gonna cum! Ugh, damn it! Seeing Mi-na like this is too much for me!"

Schlick! Schlick! Schlick! ♡ Plap! Plap! Squelch! ♡

"Cum inside me! Hahh—! Hahhh! It's a safe day, Tae-yang! Nngh—! Hahhh!"

Thrust! Thrust! Thrust! ♡ Rock! Thrust! Thrust! ♡

It was nothing short of primal—this raw, animalistic fucking. This kind of savage assault on her weakest points was one of the key triggers that could yank Geum Tae-yang's cum out in an instant. And sure enough, whenever he felt the need to shoot on time, this was exactly what he did.

Feeling the pressure building rapidly, Tae-yang's cock pistoned desperately toward release.

Meanwhile, Seo Mi-na, her ass glistening with sweat, writhed and bucked, urging him to spill everything inside her.

"I'm marking my territory in Mom's building—!"

SPLURT!GLOOOORP!—SPLOOSH!SPLAT!SPLOOOOSH!♡

Driven wild by the sight of the frenzied, heat-drunk woman, Tae-yang's cock hit its limit—

"Hahhh—! Nghh—! Hahh—!"

GUSH!

Mi-na's fingers clawed at the bathroom stall door, gripping the top edge as her body convulsed.

"KYAAAAH—! Hahhh! Hyaaah—!!"

SPLOOOOSH!SPLATTER!SPURT!SPLOOOOSH!♡♡♡♡

Her climax tore through her as she squirted violently.

"Hahhh—! Ughhh—!"

—SSSSQUEEZE!

Mi-na's climaxing pussy clenched even tighter, milking every last drop from Tae-yang's spurting cock.

"Come here, Mi-na! Fuck—! I can't believe we have to stop after just one! Chuuuaaah—! ♡"

SLAP!PLAP!♡SCHLICK!PLAP!♡PLOP!♡

"Hahhh—! Hahh—! So good...! Hahhh—! You feel so good, Tae-yang... Hahh—! Hahhh—!"

Glug...! ♡ Glug...! ♡ Drip... drip... drip...! ♡

Geum Tae-yang wiped the remaining semen from his cock with a few more lazy thrusts, then pulled back slightly to turn his beloved woman Seo Mi-na's face toward him before hungrily capturing her lips.

Mi-na, cooing softly, met his lips eagerly.

From her pussy, the thick cum that had filled her womb sloshed out in heavy, viscous waves.

And at that very moment—

Sluurrp...!

Seo Da-hye, who had just awoken to the devastating allure of her own humiliating masturbation, quietly slipped out of the second stall and exited the bathroom.

[Me]

Hah! Starting tomorrow, we'll all be living together!

[Playful Seo Ji-eun]

I'm so excited, Brother-in-law~!

[Me]

Heh~ Be prepared, Ji-eun. The moment I get a chance, I'm gonna tease you relentlessly~

[Playful Seo Ji-eun]

Unnie! Unnie! Da-hye unnie, you'll protect me, right? Promise?

[Da-hye ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠Sensei]

Got it, hehe.

[Me]

Yeah~ Not like I'll listen to you anyway~

After finishing the tour of Galleria Cheongdam, Geum Tae-yang also completed his resignation from Sejin Logistics.

Now, starting tomorrow, he would be moving into Kim Seo-yeon's penthouse.

[Playful Seo Ji-eun]

You'll listen to Hye-jin unnie, right? Brother-in-law, Third Unnie is kinda scary, you know...

[Short-tempered Seo Hye-jin]

Annoying.

Hye-jin was no different.

Their mother, Kim Seo-yeon, had sternly ordered them to strengthen their bonds as much as possible before the September wedding.

[Me]

It's not fear. It's respect.

[Me]

Hye-jin and I are partners in doing good deeds, after all.

[Da-hye Sensei]

Brother-in-law, you're really amazing. It hasn't even been a year since you settled in Seoul, yet you've been so dedicated to volunteer work.

[Me]

Hahaha! That's just how I am, Sister-in-law Da-hye.

[Da-hye Sensei]

I respect you so much...

[Playful Seo Ji-eun]

Me too!

If Seo Hye-jin was a brawler, then Seo Mi-na was a rabid dog—once she bit down, she wouldn't let go.

She had relentlessly dug into why Hye-jin had reacted so unexpectedly during her first meeting with Geum Tae-yang, and eventually, the exhausted Hye-jin spilled the truth.

'Thanks to that, Mom fell even harder for Brother-in-law. Now there's not even a shred of hope left to stop this.'

Hye-jin clicked her tongue at the flood of respect for Geum Tae-yang in the group chat.

The reason she got a smack on the back from her mother, Kim Seo-yeon, was because she hadn't spoken up sooner.

Since Hope Orphanage was a place Kim Seo-yeon herself visited, Geum Tae-yang's favorability skyrocketed beyond measure.

'It's true that he's genuinely hardworking and diligent, though...'

Still, Kim Seo-yeon had earnestly asked Geum Tae-yang to make a special effort to get closer to her third daughter.

And who was Geum Tae-yang to refuse his mother-in-law's request? He'd sooner play dead than disobey.

After work and even on Sundays, he squeezed out every possible moment to seek out Hye-jin.

Hye-jin had assumed he'd keep it up for about a week before slacking off after two, but—

Geum Tae-yang remained unwavering.

Moreover—

"Hngaaah...! Nooo... Uncle, don't get married...!"

Another side of Geum Tae-yang became the decisive factor that made Hye-jin accept her mother's demand to stay at home until her sister's wedding.

"Hye-jin unnie's older sister is getting married. So I'll be able to come here way more often with Hye-jin unnie now, So-min."

At the end of June, Geum Tae-yang went to Hope Orphanage with Seo Hye-jin.

There, he carefully broke the news of his upcoming marriage to So-min.

The girl burst into tears, wailing uncontrollably.

"But once you're married, Uncle, you'll get even busier... Sniff... And when you have a baby, you'll forget about meee..."

So-min was someone who belonged nowhere.

She knew all too well that when someone close to her found a place elsewhere, they would drift away.

She had learned that cruel lesson far too early.

"So-min, you're my closest friend. Just because I'm getting married doesn't mean we'll grow apart. I'll always be your friend, Geum Tae-yang."

Pat...! Pat...! Pat...!

Geum Tae-yang had lost his parents as a child, and by twenty, even the grandmother who raised him had passed away.

He knew, soul-deep, the piercing pain of separation.

That's why he was here—to look So-min in the eyes and make this promise.

As he stroked her head, he swore that their friendship would never change.

"Uuu... Then... If you promise to keep just one thing, I'll believe you no matter what..."

The look in Geum Tae-yang's eyes wasn't that of an adult placating a child.

This was a conversation between friends.

And So-min, with her pure heart, felt that sincerity—so she took a step forward.

"What is it? I'll do anything."

"Wh-what is it...? Whisper... whisper... whisper..."

Geum Tae-yang nodded warmly, and So-min shyly murmured into his ear.

"Hahaha! That's your wish?"

"Hngaaa...! Don't say it out loud! It's embarrassing...!"

"Got it, I won't tell anyone. And I promise—I'll make sure it happens."

"Pinky swear...!"

Unable to hold back his laughter after hearing her whisper, Geum Tae-yang linked his pinky with So-min's tiny finger and sealed the promise.

"What did So-min wish for?"

Seo Hye-jin, who had been watching from a distance, asked on their way back.

"Can't tell. So-min said it's embarrassing and made me promise not to tell anyone. It's between her and me."

For nearly twenty days, Geum Tae-yang had been in full "trying to impress Hye-jin" mode.

But despite his smile, the resolve in his silent refusal was unmistakably genuine.

'Ah...!'

It was so different.

[Daddy has something come up, Hye-jin... Let's just have fun with Mom and your sisters for your birthday, okay?]

It was nothing like the look in her father's eyes when he made promises to her.

Seo Min-jun's attitude when making promises to young Hye-jin always carried an air of "I might have to break this, but what can you do?"

And because she could sense that, Hye-jin had always been anxious while waiting.

'Lucky you, So-min. To be respected by someone so much older.'

In contrast, Geum Tae-yang treated his promise with So-min as one between equals.

Now Hye-jin understood why So-min had calmed down so quickly.

There was a sincerity in Geum Tae-yang's words that even a child's heart could trust without fear.

"Fine. I'll stay at home until Unnie's wedding."

[Good, good! That's my girl. Ah, you're so precious.]

After that incident, Hye-jin finally accepted her mother's ultimatum.

'Whoa! Galleria Cheongdam was impressive, but this place is on another level!!!'

Though he was moving into the penthouse tomorrow, Geum Tae-yang still had one major schedule left for today.

"Isn't it incredible? Grandpa built all this without any inherited capital."

He was supposed to meet Kim Seo-hui, the younger sister of his mother-in-law Kim Seo-yeon, at Terra Nova Bio Medical's headquarters.

So Geum Tae-yang arrived at the company's glass-curtained 24-story (plus 5 basement levels) headquarters on Teheran-ro in Gangnam with Seo Mi-na in tow.

"They've got every right to be as proud as any chaebol. Whether that's good or bad is another matter."

Kim Il-do was the founder of Terra Nova Bio Medical.

Though he came from a well-off family, he had essentially built the company from the ground up.

Starting as a tech firm called Il-do's Technology Works, his business weathered countless crises to become the massive biotech corporation it was today, with bases in the U.S., Europe, Japan, and Southeast Asia.

'To think the eldest daughter he had such high hopes for went and became an idol...'

For a moment, Geum Tae-yang nearly badmouthed his beloved mother-in-law.

Money wasn't everything in life, but there were limits, damn it.

At least Kim Seo-yeon was sharp enough to prove herself by becoming a self-made billionaire in the arts and culture scene.

"Still, the company vibe's changed a lot. Back when Grandpa was in charge, even the hallways felt tense. Guess Auntie and I really are alike—no way she'd let things stay that grim."

Geum Tae-yang and Seo Mi-na headed to the 20th floor, where the Strategic Business Division's head office was located.

'Mi-na's expression is definitely more relaxed than when we met Grandpa, huh?'

Within the family, Mi-na was often said to be a perfect mix of Kim Seo-yeon and Kim Seo-hui.

So naturally, she shared some traits with her aunt, Kim Seo-hui, and was the closest to her among the maternal relatives.

That's why, for today's schedule, Mi-na was taking the lead without Kim Seo-yeon.

"She's very professional about work but isn't the type to obsess over hierarchy. Cool-headed. That's where she's like me."

"If she's like you, I'm already stressed."

"Huh? Why?"

Why was Mi-na explaining Kim Seo-hui in such detail to Geum Tae-yang?

It wasn't like this was anything more than a courtesy visit for the wedding.

"Because I love you, everything about you seems adorable. If she were my boss, I'd have lost my mind by now."

"You wanna die?"

That's right.

Having resigned from Sejin Logistics, Geum Tae-yang would now be working under Kim Seo-hui at Terra Nova Bio Medical.

'Well, Mi-na's got that easygoing, slightly airheaded side to her. If they get along, maybe Division Head Kim Seo-hui is similar?'

Half of what he'd just said was a joke.

He'd already heard from the other sisters-in-law that Kim Seo-hui, despite being the company's heir apparent, wasn't as strict as one might expect.

'I've imagined a few different versions of her, but... Please just let her be a normal boss.'

Still, Geum Tae-yang kept his ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠guard up, reminding himself not to get complacent.

After all, these were just stories from family.

An outsider's experience might be entirely different.

"Division Head, your guests have arrived."

"Alright. Let them in."

Kim Seo-hui's standing in the company was evident.

Despite being a division head, she had her own dedicated secretarial office.

After being guided by the secretary-general, Geum Tae-yang finally stepped into the Strategic Business Division Head's office.

"Auntie~ We're here."

'They really are close...'

Entering the office, Seo Mi-na greeted her aunt with a bright smile as the woman rose from her seat to welcome them.

'Wow...!'

Geum Tae-yang's tongue nearly rolled out of his mouth.

He had imagined many possible versions of Kim Seo-hui's appearance.

And the one he'd hoped not to see was exactly what stood before him.

"So, you're Geum Tae-yang?"

'It's the Queen...'

![A full-width image of Kim Seo-hui exuding an overwhelming queenly presence]

So this is the dark version of Seo Mi-na who grew up under the iron rule of Kim Il-do rather than Kim Seo-yeon?

Kim Seo-hui was indisputably a queen—radiating an overwhelming aura of majesty.
