Corrupting the S-Rank Boss (1): Aphrodisiac on Yoo Ari & Wall-Slamming Kang Tae-jun♡
He repeated the same routine every day like a machine. Every morning, Kang Tae-jun bumped into Yoo Ari at the emergency stairs entrance, warmed her seat first during lunch hour, and in the evening, got his hands on the books she'd check out from the library ahead of time. Through every step, without the slightest deviation, he sprinkled trace amounts of aphrodisiac effect into her daily life—amounts so minute she wouldn't notice.
Of course, he vented the boredom of that monotonous routine and the work stress through Han Yu-jin. And at last, a week slipped by.
Today, he broke from the routine. The evening before in the library, Yoo Ari had shot him an openly suspicious glare. Too many "coincidental" run-ins for it to pass muster. For a woman who worshipped data and logic, suspicion was the inevitable next step. No more coy bullshit. His half-assed act of playing the smooth talker was doomed anyway—it was time to flip the table.
Tonight. Once all the staff clocked out and she was alone in the strategic planning office, he'd wrap it all up.
That was the plan. All day, unlike usual, Tae-jun watched Yoo Ari from afar, and just seeing her made him grin. Every little tic in her behavior screamed that his scheme was working.

Normally, she glided with flawless elegance, but today her legs trembled like she was uncomfortable as she walked, she fidgeted her ass nonstop when seated, and unconsciously crossed and uncrossed her thighs over and over.

Couldn't focus on work either—pressing her temples hard with slender fingers, biting her nails. Signs of unease utterly unlike the impeccably cold Yoo Ari. The incubus energy he'd built up over the week was finally taking hold inside her ironclad defenses, cracking her perfection bit by bit.
A sweltering heat bubbling from within, an inexplicable pounding heart, hypersensitive pussy... She chalked it up to overwork messing with her condition.
Prep phase complete. Just need to seal the deal right...
The aphrodisiac doses over the week were microscopic. Barely enough to handle with a quick masturbation sesh... But she's squirming like that means...
Yoo Ari lives like a total celibate.
Tae-jun's hypothesis was spot on. Yoo Ari had zero experience with men her whole life—not even a single sexual encounter. Confident in his read, he pressed ahead with the plan.
12:30 p.m., Exorcist Association HQ rooftop garden. No sign of that annoying newbie today. Seizing the chance, Yoo Ari unwrapped her nutrition bar with uncharacteristic ease and checked her work pad.
Then her gaze drifted below the bench she sat on. There lay a small USB chip with a name tag: HR Team Leader Han Yu-jin, in bold black letters.
...Dropping something like this? What if it had important files? Isn't this negligence?
Yoo Ari clicked her tongue softly, stood, and left the rooftop. Regulations said lost items went to the lost and found, but with the name tag and same team leader rank, she'd deliver it personally—give a greeting, issue a warning.
She crossed the empty HR office, everyone out for lunch, and headed to the team leader's room at the far end.
Knock knock.
No answer.
Out after all... Lunch hour, so I'll come back later.
As she turned to leave, a faint voice leaked from the door crack.
Someone's inside?
Yoo Ari gripped the knob and eased open the unlocked door.
That instant—
"Haaaaah♡♡ So gooood, Maaaster!! Yu-jin's pussy is meeeelting on Master's cock♡♡♡"
A vulgar, slutty moan ripped through her eardrums like a banshee wail. And the scene before her eyes...

HR Team Leader Han Yu-jin, shirt and skirt a tangled mess, bent at the waist—while that newbie who'd bugged her for a week, Kang Tae-jun, pants down, pounded into her like a beast with his throbbing meat rod.
"...?!!"
Yoo Ari's brain flatlined. Her logic circuits couldn't process the surreal sight. Wet slaps of flesh, Han Yu-jin's trashy moans, Tae-jun's savage hip thrusts. All of it—the primal human instinct she'd ignored her entire life.
Sex.
Her cheeks flushed crimson in a heartbeat, and the week's pent-up aphrodisiac erupted, ignited by the perfect visual trigger. Her lower belly clenched♡ with heat, a ticklish itch flooding her body.
"Wh-what...! What the hell are you doing here?!"
Snapping to, Yoo Ari yelled in a trembling voice.
Only then did they notice her—but Han Yu-jin kept moaning through her orgasm, unphased. Tae-jun didn't miss a beat either, casually turning his head toward her mid-thrust.
"Oh! Yoo Ari Exorcist! What brings you here?"
His brazen attitude left her speechless, but she had business: "I-I just came to return your item! And call me Team Leader Yoo Ari in the office—not 'Exorcist'!" She hurled the USB to the floor like toxic waste and stormed out, slamming the door.
Tae-jun smirked inwardly. That reaction... She's hooked good.
Then Han Yu-jin piped up cluelessly: "Hiiing♡ Master! You sure this is okay? Eut! With Team Leader Yoo's personality, we might both get stripped naked—haah♡!"
"Huh? Aren't we basically naked already?"
"Nooo♡ Not like thaaat♡♡"
"Haha! I know, you slut. Normally she'd bitch to the 감사팀 or whatever, but right now? High odds she'll let it slide."
Tae-jun slapped Han Yu-jin's ass confidently as he replied. A gamble, sure—but everything had gone to plan so far. The USB with Han Yu-jin's name, blatantly dropped under Yoo Ari's lunch bench. She would deliver it personally. Plus his hunch she'd be sexually clueless. Witnessing raw, intense fucking would rattle her psyche. It all converged perfectly. Big win.
Time flew. Past quitting time, 7 p.m.—Association building lights out, dim emergency lights glowing in the halls.
In the strategic planning office, Yoo Ari alone, lit only by her monitor as she stared at work.
But unlike usual, her fingers fumbled lost over the keyboard. Her head was stuffed with that lunchtime shock show.
Unconsciously, her right hand crept toward her skirt.
That moment.
Clack, clack.
"...!"
Heels echoed from the hall, shattering the silence. Closer... then stopped at her office door.
Tense, she stared—there stood Tae-jun, cool as ever.
"...??"
Sight of him auto-replayed lunch: Han Yu-jin's sleazy moans, sloppy flesh smacks, Tae-jun ravaging her mercilessly. Lower belly clenched♡ again, body tickled♡—unfamiliar, but not unpleasant.

Yoo Ari flinched, squirming uncontrollably. But feigning composure to uphold her S-rank dignity, she adjusted her glasses and asked coldly: "Kang Tae-jun-ssi. What business brings you to strategic planning this late?"
"Shouldn't I ask you that, Team Leader? Working overtime? Saw the light on my way by."
He answered glibly, strolling right up to her desk.
Normal Yoo Ari would've shut him down instantly—"State your business or leave"—but tonight, weirdly, she let him approach in silence.
Recent overwork stress bubbling up suppressed urges... Logical explanation for my body's reaction. Yeah...
She rationalized it analytically. No other choice really. A scrubby newbie wielding incubus powers, targeting her? That was the real stretch.
Tae-jun, no longer hiding, pumped thick aphrodisiac mist from up close.
"Isn't it risky, man and woman alone like this late at night?"
Grinning like a joke, he draped an arm over her chair back, leaning in shoulder-to-shoulder.
"Refrain from meaningless remarks."
"You really don't get it?"
Her cheeks already rosy. Confirmed, Tae-jun pushed bolder. Leaning over "papers," he "accidentally" brushed her tits with his hand.
"Hngh..!"
Tiny moan. Undeterred, he "stumbled," planting his hand on her thigh.
Yoo Ari twisted wildly, lost in her first taste of a man's blatant touch. Her mind went white-hot, reason clashing with instinct.
That instant—
BAM!!!
"Guhak!!"
A half-dome barrier exploded around Yoo Ari's body. Tae-jun, incubus-enhanced or not, got blasted back, smashing into the office wall. Even fortified, the S-rank force crushed his bones with agony.
Stunned on the floor, he squinted up, thinking: No way... She figured it out..?
