Chapter 5: Taboo Privilege
Once their lips met, they didn't part easily. They tilted a little more, aligned a little deeper. Without anyone leading, it deepened naturally.
As their breaths lengthened, the pressure shifted.
"……Mm."
Sera tugged subtly at his shirt. Junyoung, who had been bracing one hand against the wall to avoid putting his weight on her, let his wrist relax as his palm tentatively brushed the side of her waist, the small of her back. His heart pounded with a mix of tense anxiety and subtle thrill, leaving no room for worries about his rough lips chafing hers.
Their lips moved in the slightest ways, matching each other's warmth more intimately. Smack, slurp—wet friction sounds, soft enough that they could only be heard up close, kept echoing between them. In the cold stairwell air, only the heat between them spread thickly.
As Sera gripped his shirt harder, the wrinkles deepened. Junyoung's trembling hand found a bit more stability at the small of her back. Not that he couldn't run, but with a firm resolve not to let go, his breath stretched longer.
"Ha… uh…"
Unable to exhale the inhaled breath, they mingled again, and a sound leaking from deep in Sera's throat traveled through his lips. Their clumsy kiss knew no stopping point, but it didn't matter. The bare skin beneath her jacket grazed against his shirt fabric. So thin, that single layer felt utterly meaningless.
Junyoung's heated eyes fluttered shut for a moment, then opened.
"Mmph…"
Control was slipping away now. While his heart gradually settled toward its normal rhythm, blood rushed downward. In this time he'd gladly accept for a lifetime, breath hit its limit first.
Tears welled at the corners of Sera's eyes as she held back her racing breaths; they parted very slowly.
"…Haa…"
"…Uh…"
The thread-like string of saliva broke, and the sound of them swallowing overlapped almost simultaneously.
Gulp.
In the quiet stairwell, it rang out unusually clear.
Even as their eyes met, it felt different from before. No fluster, no awkwardness. A deeper heat lingered with them now.
Junyoung's Adam's apple bobbed heavily.
"Um… Ms. Yoon Sera."
His voice wasn't loud like before. But it carried a resolute determination.
"C-Can… can I do more?"
It was just the confirmation of a timid man, after all. Sera looked up at him. Her clear, teary eyes captivated him, then she slowly let her leather jacket slip from her shoulders. The black leather slid down with a soft rustle.
Finally, Sera nodded slowly. Short and clear, instead of words.
Junyoung's breath shook again. This time, not from nerves, but from acknowledging desire.
His hand wrapped around her waist again, warming her cooling body. Their lips met once more, but not fully pressed like before. Just enough distance for breaths to mingle. And in that space, Junyoung's free hand groped her breast.
Where the jacket had slipped below her shoulders, her bare skin was fully exposed, its smooth curves gleaming beautifully under the fluorescent light.
Junyoung cupped it very slowly. The soft, living warmth made him swallow his desire. It was nothing like the sensation through fabric.

The fact that he was touching such large, elastic breasts felt unreal. A privilege granted to a 0% man who had achieved nothing. A taboo privilege.
The flesh yielded subtly under pressure, then slowly restored itself, its elasticity pushing back against his palm. The hand that had cautiously enveloped it now more firmly recognized its shape.
Damn…
His suppressed desire poured into his hand, lengthening Sera's breath.
"…Uhht…"
The resilience pressing and reviving in his grasp. Soft, yet strangely firm inside. The slightest pressure changed its shape, and releasing it made it swell back proudly. He inhaled sharply.
Even while kissing, his gaze kept drifting downward. He knew he shouldn't look, but he wanted to visually confirm the source of this sensation.
Damn…
His fingers sank deeper along the boundary, disappearing from view. The difference between left and right, the volume filling his palm. A size that nearly overflowed it. Masculine perfection held him in obsessive thrall.
Even mid-kiss, his excited kneading made it clear to Sera how much he liked her breasts.
"J-Junyoung-ssi…"
Junyoung was already half out of his mind. Like a man drunk on her breasts, he exhaled long and deep. After kneading the massive mounds to his heart's content, his thumb began tracing circles slyly.
Sera's waist shivered.
"Eut…"
A small moan. Junyoung's eyes snapped wide at the sound.
She reacted.
The fact that he had elicited it strangely emboldened him. A normal woman might have said something, but thankfully, his partner was Yoon Sera. A woman who could captivate over ten men with a single exposure, yet sharing her first time with him like this—from the moment she entrusted her body to him fully, he was no longer passive.
As he rolled his thumb under her nipple and it flicked away with a tick from momentum, Sera held her breath. An unfamiliar lust made her waist tremble faintly.
"Ah, ha… w-wait… just a sec…"
It didn't sound like a command to stop. More like flustered breathing. He didn't let go of that lewd thread now.
Realizing he could shake someone like this made him bolder. Sera's hands gripped his shoulders. Her legs twisted together, bracing herself.
"…Junyoung-ssi…"
Her voice quivered thinly. Only then did he lift his head to look at her. She hadn't known her body could be this honest.
"…Th-that… feels good…♡"
Her glamorous face flushed red as she caught her breath.
"Augh…"
Junyoung trembled from the dopamine rush of excessive excitement—legs, fists, all of him—but with such an adorable woman before him, that was a luxury he couldn't afford. His head dipped lower, lips brushing her pale skin. Passing the plump upper swell, he took her nipple fully into his mouth. Short, repeated sucks made Sera's body quiver each time.
"Ah…!"
Junyoung didn't stop. If anything, he grew obsessive. Like a child determined not to miss his first taste of something sweet, he wrapped her waist deeply with the arm already there and devoured Sera with his lips to his heart's content.
Unable to endure, Sera's head tilted back, her golden hair brushing the stairwell wall.
"Ahh! Junyoung-ssi… s-stop… for a sec…!"
Her shrill voice turned ever more lasciviously feminine. Her words said one thing, but her legs twisted tighter, her hands gripped his shoulders harder. He was in a trance.
"Ha… ah…"
Her voice grew hazy. This wasn't acting for content. Beyond her control, she clutched at everything she could grasp. She knew best that her body was reacting first.
Her waist swayed subtly; tension built in her thighs, making her legs twist and untwist repeatedly. In the process, the heat from her bare skin pressed against his pants, drawing ever closer. When the insides of her thighs went strangely slack, a hot sensation trickled downward, soaking into Junyoung's pants.
And right before her relatively petite but long-legged crotch loomed the bulge of his erection straining in his pants.
Feminine instinct pulled her waist forward; after one graze, Sera kept seeking it out.
Sera's waist shifted subtly once more. The friction through the fabric teased her clit.
"Hngh…!"
Her jiggling breasts developed under his touch, drawing her into a hazy, unrealistic daze approaching orgasm. Sera thought: When will another man explore me this intently?
The rippling sensation below sharpened.
"Junyoung… Junyoung-ssi!!"
Sera wrung out his name through her trembling body. At the man buried in her breasts, slurping her nipple greedily and rapidly.
Startled by the sound, he looked up briefly.
"…Junyoung-ssi…"
Her breath quivered thinly.
"Suck it… please…"
It wasn't a request—it was thirst. Not to ride the mood or excite him like before, but purely because she craved him. Because she wanted to see that thing inside his pants that kept arousing her.
The foreplay's lead was already ambiguous. Both exciting each other with breasts and crotches, desperate and worked up.
Junyoung froze completely.
"…Sera-ssi, th-that—"
Was this the same man who'd just coated her swollen nipple with saliva while toying with it? His words faltered. He dry-swallowed once, twice.
"N-No, I mean… I'm…"
What excuse, when it was already blatantly hard? Sera looked down at him, her lips curling slightly upward. Then, as his arms naturally slackened, she slowly, smoothly bent her knees.
"S-Se-Sera-ssi—"
Without a word, she wrapped both hands around his legs. As preciously as if their meeting were a choice, not duty.
"I… want to do it."
Her upturned eyes, crescent-shaped and sparkling, shone even folded halfway.
