The Beginning of Taboo (2)

It wasn't as if Jo Yu-mi suddenly hated Mincheol and wanted to break up right then and there. With all the years they'd spent together and the memories that came with them, she was just hanging on by clinging to those old recollections. She was growing more and more exhausted, weighed down by the pointless mental energy she had to pour into it. The closer he tried to get, the more she had to push herself away. She had no interest in keeping up the relationship like it was some given, let alone letting it escalate in a whirlwind like that.

But that one night with the male junior—and the raw, intense sex in the club room—had rattled her brain. Her entire mindset crumbled. She'd thought she wasn't the type to waver over a single fuck, but the thrill and ecstasy lingered in her body, hijacking her thoughts. The texture grazing her inner walls, that rigid length plunging all the way to the hilt. The brutal grip seizing her breasts. It kept replaying, kept feeling real. She'd never understood women who chased pleasure without a second thought to their lives, but now here she was, one of them. She'd had plenty of time to mull it over, but she'd already gotten a taste. A once-pure woman falls fast to that dizzying rush of bliss.

Paradoxically, it even muddled whatever lingering feelings she still had for Mincheol. The fling with her junior—born purely out of spite for Mincheol—had upended everything. Still, she had no plans to treat him like some slut who'd spread her legs for anyone. Chastity wasn't up for debate after sleeping with another guy, but ever since that ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠day, it wasn't other men haunting her mind—it was sex with Seonghwan. And yet, the junior who'd unlocked woman's pleasure for her hadn't pushed his luck afterward. Caught between her status as "senior's girl" and his crush on someone else, he'd stalled out.

That's how she knew: the second she cleaned up her mess and went to him, he'd bolt. She'd spent the last few days wallowing in self-disgust over how little he seemed to think of her, agonizing... but in the end, she had no choice. No matter how he saw her or what he misunderstood. She just hoped it'd keep going burden-free like this, and she'd deal with the future when it came.

Yu-mi had wrestled with it plenty. Worried plenty. And decided to just go with her gut.

Seonghwan lay there, eyes bulging as Yu-mi straddled him and stripped off her clothes.

As expected... Yumi sunbae's tits...

Just two hours earlier, he'd been holding Min Yu-ri, kissing her, sucking her breasts. Yu-ri's were plenty big and perfectly shaped, but the pair right in front of him now? Yu-mi's breasts were on another level—massive, heavy, bouncy.

Even with Seonghwan still in just his boxers, Yu-mi didn't hesitate. She shed everything, flaunting her killer body like it was nothing.

She grabbed his hand and pressed it to her breast.

"I told you, didn't I? Where my sweet spot is?"

"...Tits."

"Bingo."

The words barely left her mouth before Seonghwan clamped down hard.

"Ahhhng. Yeah, that. Aaaah."

Insertion? Not even close. But her moans from just her tits alone had his cock surging to life. Seonghwan sat up, burying his face in them, sucking greedily.

"Huuuuung. More... more."

"Haup."

Smack smack smack smack smack.

Her nipples hardened under his tongue, perking up perfectly for the hard suction. Churu-rup.

"Ahk!!"

He grazed one with his teeth mid-lick, and her back arched, breasts ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠jiggling wildly. Seonghwan seized the escaping flesh and latched back on.

"Haguk."

Her moans turned filthier by the second. Seonghwan couldn't take it anymore. Hands locked on those massive tits, he shoved her—the girl astride his thighs—flat on her back.

"Fuck."

The curse slipped out unbidden. The second she hit the mattress, he spotted the slick gush from her pussy.

Fuck, this the same virgin from the other day? How many dicks has she taken to get this slutty?

He had her all wrong, but even if Yu-mi knew, she'd probably skip the excuses. Rage and jealousy boiling over, Seonghwan rammed his fingers into her without mercy.

"Ahhhng."

Plop plop plop splash splash.

She thrashed like she might pass out, hips bucking wildly at his brutal fingering. Splurt splurt. The wet, sticky friction of her ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠juices and his fingers nearly made him blow his load right there.

Not yet. Might as well try everything I've ever wanted today.

Eyeing her flailing arms and lewd convulsions—pleasure or pain, who cared?—he climbed onto her stomach.

"Haa... why?"

Ignoring her, he squeezed her tits and tweaked a nipple. It quivered lewdly. Still pinching, he yanked them sideways. The heavy mounds spread slowly in his grip.

"S-Seonghwan... what're you—?"

He met her flushed face, cock standing proud. "Can I... try something I wanna do?"

Consent? More like predator's privilege. She nodded quick, eyes gleaming with barely hidden thrill as she stared him down. Emboldened, Seonghwan plunged his dick between her tits.

"Hap...?"

Those twin globes swallowed him whole.

"Huuup."

The squeeze alone had his spine tingling, orgasm teetering on the edge. Not yet. Ngh.

Gritting through it, he bore down harder on her tits.

"Ahhhk."

Squish. Her lewd wail escaped as precum beaded, but his face stayed stone. He started thrusting.

Splurt splurt.

"Huk huk huk huk."

Shivering in ecstasy, he didn't stop. Soon enough, Yu-mi took over, clutching her own tits to egg him on.

"F-Fine... harder. Whatever you want..."

Keuk?!

Her words clubbed the back of his skull. A busty goddess spewing filth like that? Emotion and bliss crashed over him. Reason gone, he pistoned wildly—still pinching, twisting her rock-hard nipples mercilessly.

"Hahhhk. R-Right there. Like that. Hahk."

A woman whose kink was her nips. Owner of tits so rare in this cramped country. And she was clinging to him, sex-mad.

"Hahng. M-Me too... enough now..."

He got the hint. Releasing her rack, he slid down, groping for her dripping slit. Squelch.

...Drenched. Fucking soaked. Gonna lose it.

Her nectar coated his fingers thicker than ever—like it embodied her pussy's desperate hunger for him. He notched his tip at the weeping entrance.

"Uhng."

She sensed it, anticipation dripping from her voice.

"Huuu."

He lined up and slammed—

"Euk. Damn."

Yu-mi's phone blared right as he thrust, screen glowing. Seonghwan groaned in frustration at the cockblock. She fished it out, checked—and shot him an amused glance from below.

Huh?

Her look jolted him; he peeked. What the fuck?

She thumbed the answer button anyway, ignoring his frantic shooing gestures.

"Yeah. Why?"

- Where are you?

Shit... why now?

Regret soured his gut, the throbbing lust and near-climax fizzling out. Catching his pouty stare, her eyes sparkled mischievously.

"I'm at Yuyeon's."

- Yuyeon? That friend studying abroad?

Seonghwan clocked it—Yuyeon, her old roommate and classmate from before she moved in. Her innocent reply came as her hand drifted south, snaring his raging cock.

Euk? Y-Yumi sunbae?

He grabbed her wrist in panic, but she held firm—already bowing her head toward his crotch.

Why...?

He knew exactly why. Every guy fantasizes: another dude's girl, hooked on you, blowing you mid-call with her man. Just a fantasy!!

But fantasy turning real? His brain shorted. She stroked him slow, heat reigniting—snapping him back.

Lick. Her tongue flicked his glans; he twitched, shaft quaking.

"Heup."

He clapped a hand over his leaking moan.

- Why're you quiet?

Mincheol sounded impatient.

"Yeah, Yuyeon's."

- What? Why there all sudden?

Smoooch. Her lips grazed the head.

"...To crash."

She winked up at him, glans between her teeth.

Chill. Her slutty vibe electrified his spine.

- Didn't you say you were heading home?

Haaaup. She engulfed half his length ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠in one gulp.

"Cough... krup."

- Hello? You okay?

"Candy got stuck in my throat."

She eyed him with cutesy lilt, revving him higher.

- What candy sticks like that?

"Got one. Big candy. Way bigger than the one oppa got me last year."

Seonghwan yanked free—he was seconds from bursting. Reality never lives up to fantasy, right? Bullshit. Fuck. You try this taboo rush. How the hell do you hold back?

No saint here—just a horny young guy, urges always simmering. Yuri and Yu-mi were making them real; her depraved play snapped his moral leash.

Today's Yu sisters are out to kill me. Yuri's bathroom exposure stunt. Yu-mi's boyfriend-call fellatio. Peak madness.

Then—

- You doing something shady? Voice sounds off from our usual calls.

Mincheol's suspicion crackled through. Seonghwan glanced at Yu-mi; she met his eyes. Contact made, she eased back, spreading wide. Mouth agape, she mouthed: It's. Fine. Fuck. Me.

Then he got it. For him? For her? Didn't matter—this moment, she craved him ditching all else for her pleasure. Her quivering gaze screamed matching ecstasy. And that possessive glint... claiming him utterly.

He slammed home into her pussy.

"Kyaaaahng!!"

Her scream drowned Mincheol's chatter, filling the room. In that instant, Seonghwan felt the chains of propriety shatter—for the first time.

And just like that, he tasted true taboo.
