33. The Sister Devouring Brother-in-Law's Cock, Sister-in-Law Da-hye Who Ultimately Got NTR'd(?) by Brother-in-Law. "This is weird...? Is it vulgar...? Is this what a pussy looks like...?"

Drip...! Ssshh! Drip-drip-drip...!

The moment her panties came down, the state of bride-to-be Seo Mi-na's pussy was revealed—

A plump, dripping cunt, gushing slick juices as if she'd downed some kind of aphrodisiac. What was even more astonishing was her attitude. She acted almost as if she were pleading, Don't think of this lewd display as strange, while putting on a fragile front.

'This is weird, unnie... How is she making those sounds...?!'

At first glance, Seo Da-hye concluded that either her sister's mind or body was far from normal. Either her mind was so messed up that she was genuinely pissing herself in front of her future husband,

Or her body was so out of whack that her arousal fluids were leaking like urine. Struck with disbelief, Seo Da-hye trembled, her hands and lips quivering.

"What a hopeless pussy."

Shake... shake...!

Meanwhile, Geum Tae-yang, who was witnessing Seo Mi-na's performance firsthand, clicked his tongue in an oddly fascinated tone and shook his head side to side.

"Come here! I'll love you properly!"

‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠

Splaaash!

"Hhhuuuuuhh! I liiike it...! ♡"

He was pleased. The sight of Seo Mi-na—a woman who carried herself like a seductress yet pretended to be delicate—

It was the perfect image of a lust-crazed female, one that stoked the flames of his machismo. Geum Tae-yang wrapped his arms around Seo Mi-na's slender waist and yanked her toward him roughly.

"Grrrr...! Pussy...!"

Squelch! ♡

"Tkhuuuuuuhh!"

Jolt! ♡

Then, he grabbed hold of his future bride's plump, dripping cunt—the very pussy he'd be legally fucking in a few months—and squeezed it hard.

In response, bride-to-be Seo Mi-na shuddered violently, unable to suppress the moans rising from deep within her.

'B-Brother-in-law...! He just grabbed unnie's—her there! And he called it a pussy...!!!'

The unmistakably wet sound of a soaked cunt being roughly palmed by a large hand reached Seo Da-hye's ears in full clarity. No matter how much she wanted to deny it,

And on top of that, Geum Tae-yang's cock throbbing from his dantian was just as audible as Seo Mi-na's moans,

So Seo Da-hye could vividly picture exactly what her brother-in-law was fixated on right now.

"Beyond just damp—it's soaked... Once you become an adult, is this how much you're supposed to leak from your pussy, huh? Answer me, Seo Mi-na..."

Squish...! ♡ Squish...! ♡ Squish...! ♡

"Hhhuuuuhhn...! Hhhk! Hhhuuuuuhhn...! Hhhn! Hhaaahhn! Hhhuuuuuuuuh...! I liiike it...! Hhhuuuhn!"

"Not answering, huh? Your future husband asks you a question, and you just moan and collapse instead."

Squelch...! ♡ Squish...! ♡ Squelch-squelch...! ♡ Squish-squelch...! ♡

Geum Tae-yang lovingly kneaded Seo Mi-na's plump, slick cunt. His words were downright vulgar, dripping with gaslighting,

But Seo Mi-na didn't care—she was too busy reveling in the sensation of his hands worshiping her pussy, even shutting her eyes to focus on it.

"The problem is that you're just too damn lovable! Hhhuuuhn! Tkhuuuhn! The problem is that I just wanna fuck you, you little bitch! Hhaaauuuhn! Hhhuuuuhn! Tkhuuuhn! Don't blame me, you bad girl—ahh! Hhhuuuuhn!"

Bounce! ♡ Bounce! ♡ Swayyy—bounce! ♡ Bouuunce! ♡ Bouunce! ♡

"How can you be this adorable?! It's driving me insane! To the point where I'm making a scene right where your mom works?!"

Squelch! ♡ Squelch-thrust! ♡ Squelch! Squelch-thud! ♡ Squelch! Slam! ♡

"I'm going craaazy...!! Hhhuuuuuuh! Hhhuuh! ♡ Hhhaaauuuuuuh! ♡ If I can't feel you right now, my head's gonna explode—hhaaauuuhn...! ♡ Hhaaah! Hhaaauuuhn! ♡"

Pat... ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠pat... pat...

"Damn it, Seo Mi-na! You're obsessed with me!"

The genius artist with her plump, dripping pussy displayed extreme emotional swings. Cursing like a sailor while twerking on Geum Tae-yang's hand as if devouring it,

Eyes brimming with tears while nuzzling into his touch—

To an outsider, it would look like they were high on something and fucking right then and there.

'Hhaaahhh...! I can't understand this exchange of emotions... What in the world is this love between brother-in-law and unnie...??'

Still, wasn't Seo Da-hye the one who communicated best with her sister in the family? She'd seen all sorts of her sister's eccentricities and had tried to understand them.

But this? This felt like hitting a dimensional wall.

"That's right! Feel my love until it drives you insane, Seo Mi-na! Get up here!"

—Flash!

"Hhiiiiiiuuuh...! Finally... Tae-yang's cock... Hhaaauuuhn...!"

Geum Tae-yang lifted Seo Mi-na's body while holding her waist. "Hngggh...! Does it really have to be this position...?"

"Deal with it. This is the love space you chose."

Thud! Thud! The position for penetration was set. Geum Tae-yang remained seated on the toilet, while Seo Mi-na braced one hand against the wall behind the toilet and shamelessly spread her legs, settling over his lower body. It was just shy of the so-called sitting cowgirl position.

"Good... decadent and filthy... Perfect for tasting my Tae-yang's cock..."

Squish...! ♡ Squish...! ♡ Squish...! ♡

Seo Mi-na aimed his cock at her pussy, stroking the thick shaft obscenely with her lewd fingers.

'She's doing it...! She's really doing it!'

Seo Da-hye, frozen in place, clamped both hands over her mouth. She could practically feel the moment her brother-in-law's cock and her sister's pussy were about to go wild. Gllrrk...! ♡ Blrrp...! ♡

Then, with practiced ease, Seo Mi-na lowered her plump ass, pressing her aroused pussy flush against the head of Geum Tae-yang's cock.

"Nghhaaahhh! Hngghh!"

Schlluuurp! The moment she felt the lewd connection of cock and pussy, she threw her head back and howled like an animal. Even though full penetration hadn't happened yet, the sight was undeniable—a completely natural reaction, not an ounce of pretense. Drip...! ♡ Drip...! Splurt! ♡

'Ghhhaaah! Even the entrance feels insane!'

The spectacle unfolding was more than understandable. The moment the head of Geum Tae-yang's cock pressed slightly into Seo Mi-na's pussy, her folds gushed like a waterfall, splattering her juices. To Seo Mi-na, Geum Tae-yang's very body—no, love itself—was like an intoxicating drug.

Trembling at the sight of Seo Mi-na's unprecedented arousal, Geum Tae-yang felt not just exhilaration but the primal pressure of a male needing to satisfy his mate.

"Nghhaaaahhh! Hngghh! ♡"

Thud! Thwack! Seo Mi-na's reactions escalated further. Tipping her head back wasn't enough—she slammed her free hand against the bathroom stall wall.

'Haaahhh...! What do I do...?! What do I do?!'

Was this the love between her brother-in-law and her sister? The pure love of first love? Was the physical love between lovers nothing more than animalistic mating?

Seo Da-hye, who had always held fairy-tale illusions about love between men and women, felt as though that very storybook was being torn to shreds before her eyes. She clutched her mouth, her expression on the verge of tears.

[Love makes everything beautiful when you're inside it... Once you fall in love, Da-hye, I think you'll understand what I mean...]

'Even so, Mom... I can't accept the shocking scene happening right next to me... Am I the one who's wrong? Is it me? Am I just being fake?'

And then there was Kim Seo-yeon—Seo Da-hye's mother, the roadmap of her life.

Seo Da-hye recalled the stories Kim Seo-yeon had told her about lovemaking between couples, but none of it matched this. She felt like she was about to have a mental breakdown.

"Hhhaaahhh...! Hngghh...! Nghhh...!"

Squelch...! ♡ Squish...! ♡ Slurp...! Slurp...! ♡

Regardless of her little sister's turmoil, Seo Mi-na, reveling in the explosive pleasure unfolding in her mother's office bathroom, began rocking her hips.

She gripped Geum Tae-yang's cock firmly, stroking it in reverse while grinding her pussy against him—starting a lewd cock-pussy frottage.

Squelch...! ♡ Squelch...! ♡

"Ghhhaaah! That squelching pussy of yours, Mi-na!"

Glrrsh! ♡ Glrrsh! ♡

It was the sound of Seo Mi-na's dripping-wet pussy, already in the throes of extreme heat. Even though they were only grinding, the head of Geum Tae-yang's cock was already nearly swallowed by her slick folds.

In this state, Geum Tae-yang could feel every inch of his future bride's thick, slippery, and deliciously textured pussy pressing against his sensitive glans. The stimulation shot straight up his spine, piercing through his frontal lobe, making him grab Seo Mi-na's plump 41-inch ass like he wanted to break it.

"Hhhaaahhh! So gooood...!"

Rock...! Rock...! ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠♡ Twist...! ♡ Buck...! Rock...! ♡

Seo Mi-na, relishing the way her lustful body moved, could feel Geum Tae-yang's raw excitement through his trembling grip.

For Seo Mi-na, seeing the man she loved brought to the brink of ecstasy because of her sent her primal feminine satisfaction and self-worth skyrocketing like a blood sugar spike. She rolled her hips even more dazzlingly.

"Khuuuu...! Shamelessly bouncing on his cock like this... my plump, round ass... my big, jiggly peach... the pure, untouched rear of your bride-to-be, Seo Mi-na..."

Slap!♡ Smack! Slap!♡

"Hhaaang! Hahhht! Because it's my man's cock... hhuuuuhn! The cock that took my virginity... ngh-haaht! Tskh! Haaahhh!"

Driven mad by Seo Mi-na's wanton allure, Geum Tae-yang spanked her ass. At this point, even he no longer cared if someone walked into the bathroom.

'Everything unnie said was true... All this time, while brother-in-law was making love to her like this... when he was texting me... texting me...!'

Thud-thud...! Thud-thud-thud...! Thud-thud-thud...!

Seo Da-hye was forced to indirectly experience Geum Tae-yang—a sex machine with its reins cut loose. Her mental state teetered on the verge of a breakdown.

Caught between the image of her simple, honest brother-in-law and the femme fatale duality of his true nature, Seo Da-hye's soul seemed to leave her body as she babbled incoherently.

"So you'd better take responsibility for me, you bastard—hyaaahk!"

Squelch!♡ Glurp!♡ Thrust-squelch!♡

And in that moment,

Seo Mi-na shot a coquettish glare at her future husband while lowering her plump, no-longer-virginal bridal hips—which had just been thoroughly spanked—down with deliberate slowness.

Thus, as she sank down, her ample 41-inch hips swallowed her fiancé's 23cm arm-thick cock in one devastating stroke.

"Khuuuuuuuk!"

—Sluuuuuurp!!

Wham!!

A perfect, single-motion penetration.

This was only possible because Mi-na's physicality was extraordinary to begin with, and after nearly two hundred rounds of sex, their compatibility had reached flawless synchronization.

But above all, it was Mi-na's sheer audacity—her unyielding determination to love and cherish Geum Tae-yang's extraordinary cock wholly as his bride—that had manifested at 200% capacity.

Perhaps sensing the depth of this first-love devotion,

Tae-yang straightened his torso, pressing their bodies flush together as he embraced Mi-na's waist with even more reckless abandon.

"Tkheuuuuung! Heuuuuung! So good!♡"

—Squelchhhhh!!

Thanks to Tae-yang's embrace,

Mi-na arched her back like a drawn bow, explosively savoring both the triumphant fulfillment of full penetration and the cathartic rush of pleasure.

'It's inside... Brother-in-law's thing... inside unnie's...'

Clench...!

The 23cm cock had successfully docked into her slick, faucet-wet pussy.

The sheer carnality of the penetration was so intense it felt like genuine human genital coupling—and then, as if on cue, the paired beasts shuddered in unison, their moans bursting forth in shared ecstasy.

Seo Da-hye bit her lip hard, overwhelmed by the inexplicable sensation, and shut her eyes tight.

"Hhhuuuuu...! Hhuuung...! Hhuuuuuuu...!"

Pant...! Pant...! Pant...!

"Khuuuu... Why do you push yourself so hard, you reckless girl..."

Squish...! Squish...! Squish...!♡

Mi-na's chest heaved like overinflated balloons as she gasped for breath, her body still reeling.

As the explosive catharsis mellowed into a lingering afterglow, the delayed strain of that single-stroke penetration finally caught up to her.

Tae-yang, barely holding back his own climax, kneaded her tightly clenched pussy and grumbled teasingly.

"Shut up... You're so damn tight I can't even fuck you properly yet... Hhuuuu...! Hhuuung... Feels good, doesn't it? Driving me insane, you precocious little bastard? Hhuuuung..."

"W-what nonsense! I'm just treasuring my fiancée's pussy properly!"

But by now, Mi-na could read every nuance of her beloved male's condition just from the subtle twitches of the cock buried inside her.

This was their first time having sex outside the semi-basement room, and Tae-yang—overwhelmed by excitement—had been teetering on the edge of orgasm from the very start.

"Don't worry... It's me... Your first love, your fiancée Seo Mi-na... You can cum right away if you need to... I'm happy just being like this with you..."

Squeeeeze...!♡

"Tch! Who's the pervert here, huh...?"

Mi-na was the pinnacle of push-and-pull.

Countering Tae-yang's gaslighting with her own masterful teasing, she soothed his bruised male pride with a voice dripping with maternal affection, pulling his head into the pillowy embrace of her ample breasts.

"Calling me a milk cow, huh...? Smooch! Smoooch!♡ ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠My hips are plump and bouncy too... Smooch! Smooch! Smoooch!♡"

Squish...! Squish...! Squish...!

"Hhuuuung...! So good... Hhuuuuu... My Tae-yang's such a child... Hhuuuuu...!"

Overcome by the warmth of her maternal aura, Tae-yang buried his face deeper into her soft bosom, suckling greedily.

All the while, his hands kneaded her generous 41-inch ass as he muttered like a tsundere brat.

Watching her beloved golden boy like this, Mi-na closed her eyes gently, savoring the fulfillment of a female who had claimed her male.

'I can't bring myself to look away... What kind of emotion is this even...?'

They hurled insults, even outright cursed each other—only to embrace tenderly after penetration.

All within the span of barely ten minutes.

Seo Da-hye, a virgin who still clung to naive romantic fantasies, couldn't make sense of it.

'Then why is my heart racing like this...? It's clearly wrong... This isn't what Mom told me it would be like...'

Thump! Thump! Thump! Thump!

Her mind refused to comprehend, but her heart pounded violently—as if sex wasn't an experience for the brain, but for the heart alone.

"Does my Tae-yang like his noona's breasts...? Do you feel safe nestled between them...?"

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

Slurp...!♡ Slurp...!♡ Slurp...! Slurp...!♡

"Khuuuuk! W-well... I won't deny it..."

Squish...! Squish...! Squish...!

But as if the real experience was only just beginning,

Seo Mi-na—older sister of Seo Hye-jin—buried her younger sister's brother-in-law's head deeper into her chest while slowly rolling her hips,

methodically devouring her fiancé's massive, delectable cock.

Tae-yang couldn't suppress his shudders.

Drawing a deep breath, he passively enjoyed his bride's skillful riding, his hands idly kneading her ass in vulgar appreciation.
