Back to Being a Salaryman 5

U Mi-young's face was a perfect blend of intellectual elegance and subtle sexiness. She reminded me of some movie actress... [0, 42, 0]
U Mi-young, the section chief, had no experience with blowjobs or anal sex. I'd assumed she was pretty experienced overall, but that was surprisingly not the case. Maybe she just wasn't that into sex. She favored luxury dresses, always tying her hair back in a neat bun—which sparked rumors she was ex-flight attendant material. True to her fame as one of the office's "Three Beauties," she stood over 174 cm tall, slim and statuesque. That haughty expression screamed confidence in her own beauty. And get this—she was dating our department head, Choi Dong-jin! Only I knew that little secret.
Choi Dong-jin was forty-eight, a divorced dad with a grown daughter. But damn, he looked ageless, like a total hunk in his mid-thirties. A twenty-year age gap with U Mi-young. Sure, I could admit the guy had charm and talent. But she was practically his daughter's age! Must've been some hidden masculine allure that hooked her. Water under the bridge now. U Mi-young was just another shell.
The shell that used to be Choi Dong-jin's girlfriend was still staring at my cock. No expression on her face, but I could see her swallow hard. What was going through her head? She didn't seem that into sex... She'd never shown anyone a secret fuck session like this.
U Mi-young took another sip of her honey water, then slammed the cup down on the counter with a sharp thunk! Gu Mirae flinched at the sound. U Mi-young turned and strode out, her hips swaying lightly as she pushed open the pantry door. Thud. The door clicked shut softly, and Gu Mirae's pussy relaxed with a slick slide. She'd been tense, alright.
Our fuck was something U Mi-young had never witnessed. Must've been a first for her—office pantry routine and all. Honestly, if I was being really honest... I'd fantasized about U Mi-young craving my cock. Got hard hoping for a threesome. No reason to turn down a woman who wanted me. If Gu Mirae and I could've talked, we'd have chatted about it.
"Park, why'd Chief U just leave like that?"
"Who knows? Maybe she didn't wanna fuck me."
"Come on~ You're packing serious heat, sir! Too humble, aren't you?"
Imaginary convo, but that's how Gu Mirae would've played it. I gave her lips a light kiss, planning to end it there—but her tongue poked back into my mouth, prodding playfully. She wanted more.
"Gu Mirae. You were a virgin today."
She beamed at me, all smiles. Guess she loved the rough pounding while talking dirty like a cock sleeve. My lust was bottomless, and so was hers now. I slid back into her gaping hole—perfectly molded to my size. We fucked like college kids high on their first time, eyes wide open to the addiction. Three and a half hours total. Glancing at the clock, quitting time was closing in.
"Urghhh!"
I thrust hard one last time, unloading deep into her ass. Hot cum flooded her depths. Her body stiffened, then shuddered violently. She climaxed with me. Dopamine explosion should've loosened her tongue like before, but no words came. Wasn't dopamine supposed to make shells talk? Whatever. We'd figure it out with more research.
I released her throat. She gasped raggedly, trembling. I slowly pulled out—cum dribbling from her ass.

Pssshhh—psshk! Gu Mirae was utterly spent, legs wobbling. I held her steady. She nestled into my arms, catching her breath, face glowing with bliss—like she owned the world. If she had a tail, it'd be wagging like crazy.
"Gotta wash up."
Her face and hair were caked in my cum. I led her to the sink. She started rinsing as water flowed, smudged makeup swirling away, clean face emerging. No makeup, and she was still gorgeous. I grabbed wet wipes, cleaning her pussy and ass. Our mixed fluids soaked the wipes. She stood still, letting me tend to her.
Blurp-blurp-blurt! Pussy fart echoed as juices gushed again. My touch reignited her heat.
"Haaah... ahh..."
Every wipe stroke made her drip endlessly, soaking her lower half anew. Wipe, drip, repeat—like Dormammu regenerating. Keep this up, and we'd pull an all-nighter. I handed her the pack to finish herself. Even light touches triggered floods. Side effect of breaking her virgin too rough? She'd imprinted as my personal fuckhole.
"Stamina for days."
She grinned wide again.
"Wedding next week, right?"
She nodded.
"We'll keep meeting though?"
Vigorous nod, eyes full of certainty. Light kiss on her lips. Wild part? My endless stamina. If food ran out, I could churn protein jelly from my cum. My body felt rebuilt for fucking. Demon hunter perks, clearly—humans couldn't cum this much. College record was eight loads before my dick root ached. Today? Over twenty, no pain. Including subway, Jin Sun-mi, and Gu Mirae sessions.
I taught her positions one by one. Quick learner, curious as a student—nailed slutty cock-sleeve moves perfectly.
Gu Mirae checked herself in the mirror. Face clean, but eyes still burned with lust. She slipped on her bra and pads, sculpting cleavage from nothing. Ah, so that's how she fakes it. Bet I could pull that off too. Instant overflowing B-cups. Tough life with small tits. She grabbed her blouse from the floor after buttoning up—but froze at the missing buttons.
"Oh."
Shells all react the same when shocked. Eyebrows sky-high, mouth in a big O—pure cartoon. When she ripped it off in heat... Now empty eyes darted around. I stripped off my undershirt and handed it over. She wore it instead of the blouse, topped with her jacket. Looked decent. Grateful Joker smile at me. Non-sex Joker grins were default. Wish she'd soften it up sometimes.
Dressed, she raised her arms and toddled to me cutely, crashing into a hug. Looking up, lips pouted. Quick peck, then a smack on her ass. Flat chest, but ass was top-tier. Probably bruised from all my spanks. She headed to her desk first.
Routine and desire. Shells were simple. Gu Mirae's twisted craving for me—saving her virginity just for me. Her strongest urge was me. Mind-blowing. And they could learn, like Photoshop new tabs. She mimicked positions well, though not flexible Jin Sun-mi's ballet or flip-phone poses.
Question: As a shell, she only mimicked forms, no context. Stuck to memorized actions. Recalled her pantry wall-slam kiss. "Where'd she learn that seduction?" Shells repeat familiar, not improv. Probably from her romance novels. Knew she loved them—saw CEO Kim's Too Much on her desk. Wall-slams galore in women's romance. High odds.
Can't chat, so frustrating. They adapt learning for lust relief. She doesn't read anyway—confiscating CEO Kim's Too Much. I'll read it. Might unlock more Gu Mirae insights.
Stepped out—hallway empty, thank god. Everyone glued to keyboards. Easy paycheck, suckers. Wait, paychecks? Economy's dead, money's worthless. Not my problem.
Sat down, eyed Gu Mirae. Photoshop menu clicks—new tab, drawing now. Good girl, remembered the lesson. She glanced up, brushed hair behind ear, Joker smile. I smiled back.
[225, 12, 163]
I took her virginity. Felt weirdly proud. Wedding next week, but right now? Mine.
"Heh..."
Checked my desk mirror. Post-cum, lifespan shot up past 10,000—countdown vanished. Sex extends life endlessly. Freaky world.
At 6 PM sharp, Choi Dong-jin bolted up, clapping.
Alright, everyone—time to clock out!
Classic: no matter the workload, he forced clock-out. Right on cue, up he went, clapping silently with a Joker smile. Everyone rose for exit prep. Next department peeked like meerkats, envious as always. Pre-apocalypse routine.
U Mi-young watched me intently, observing. Why me? Unsettling. Glanced at Gu Mirae—adorable nose scrunch smile. Secret grin back.
Gu Mirae punched out first, heading out. Followed for post-work drinks or dinner. Touched her shoulder—she frowned, slapped my hand, spun, and stormed off with contempt.
What the?
180 flip baffled me. What'd I miss? Her head numbers unchanged: [225, 12, 163].
Ah...
Oxytocin bonds groups. Was our fuck just "boss-subordinate" extension? Real Gu Mirae skipped after-work drinks, strict work-life split—no calls post-quit. So she saw pantry sex as overtime? Explained the ice-cold exit.
Head-spinning. Then... Jin Sun-mi too?
Grabbed CEO Kim's Too Much from her desk. Useless to non-readers.
A bit bummed by post-quit Gu Mirae shift. But figuring out how to control off-hours her? Kinda fun. Until I could invite Jin Sun-mi and Gu Mirae home for a threesome.
Empty office. Flipped open CEO Kim's Too Much midway. What kinda novel...?
"N-No... This won't do..."
CEO Kim's cock struggled into Deputy Manager Nam's ass.
Fuck, it's BL.
