Senior Yena and the Couple Secret Unlock
Just hearing the word "couple" made my face burn hot.
"C-Couple panties? Isn't this just a coincidence?"
Even so, it felt like Assistant Manager Lee Yena had deliberately rummaged through the pile of underwear.
Otherwise, why wouldn't any pair have sufficed?
Regardless, she ignored my question and fixed her gaze on my lower body.
"Oh my, the fit is no joke. Dohyuk, have you been working out your lower body hard? Your thighs are so firm."
Without a hint of hesitation, Assistant Manager Yena scanned my lower half with obvious interest, her eyes lingering especially long on my cock, which strained angrily against the thin silk fabric.
"By the way, this is perfect timing, Dohyuk."
"Yes? What do you mean?"
"Next week, we're shooting an ad for this Couple Panties lineup in an adult magazine. The professional models just don't capture the wild, healthy male vibe this product targets. They're all too skinny."
Resting her chin on her hand, Assistant Manager Yena took another step closer. A faint, sweet scent—her signature fragrance—washed over me. Maybe because she was only wearing panties, I could also catch the subtle scent of her pussy that I'd noticed during the interview.
...Mmm... I'm getting horny...
My sense of smell remembered. The overwhelming arousal I'd felt when I touched Assistant Manager Yena's pussy.
"So, how about it? Will you rehearse the shoot with me?"
"...Rehearse? Here?"
"Yeah. We're both already wearing the products. Let's check how appealing the poses will be to customers."
...This was absurd. No matter how much of a lingerie company this was, did she really expect me to rehearse an underwear ad with a male junior in the laundry room?
"Senior, this is still the office, no matter what..."
"Ahem. Newbie. Did you forget the chain of command?"
"......"
It felt like watching the cycle of workplace bullying repeat itself. Did she treat her juniors the same way her superiors treated her?
No way. There's no way Assistant Manager Yena, who's like an angel, would do that... Look at those doe-like, sparkling eyes... I'm going crazy...
...Thinking too deeply about it was complicated, but if I treated this as just part of the job, it would be easier on my conscience. Above all, if I got fired from Eve Secret, I'd be stuck bouncing between small and medium-sized companies... I couldn't throw away this high salary over a careless decision.
I'd just do as she instructed.
At that moment, Assistant Manager Lee Yena tapped my lips with her index finger and smiled seductively. Then she gave an order I couldn't refuse.
"First, hug me from behind."
"...Excuse me?"
"Back hug concept. We need to see how lewd these panties look when a man's firm thighs press against a woman's ass. Hurry up."
She spun around and thrust her plump ass toward me.
"Ah......"
I needed to use some crude language for a moment. Assistant Manager Yena's ass... was fucking firm and bouncy. I wanted to grab it with both hands and squeeze it wildly.
Haa... I'm seriously losing my mind. Why is this trial happening to me...
"...Dohyuk? What are you doing? How long are you going to hesitate? Did you suddenly turn into a statue? Where did that eager, quick-witted newbie from earlier go?"
"...No, ma'am! I-I'm coming right now!"
Yeah. Let's just do it.
I swallowed hard and carefully wrapped my arms around her slender waist.
Swish.
Hugging the delicate Senior Yena from behind, I felt her warm body heat and soft skin. It felt like even the unspoken wall between us was crumbling.
I wanted to just pull her panties aside right there and shove my cock into her pussy.
Ah... My cock is acting on its own... Stop...!
If we were on a bed, I'd pin her down completely, but this was the workplace. I was a man who separated work from personal matters. That was me.
For now, I only followed Assistant Manager Lee Yena's instructions.
Squeeze—
"Hn...!"
The moment we pressed together, a short moan escaped her lips. Of course it did—my throbbing cock had settled perfectly between her soft ass cheeks. Through the two thin, smooth layers of couple panties, the hot, hard sensation was shared vividly.
"Dohyuk, what's that hard thing? An e-cigarette?"
"...I don't smoke. This is..."
"It feels... like a weapon..."
"Assistant Manager... it might be dangerous-looking, but it's not that kind of weapon, so please don't misunderstand..."
"Mmm... There's no way you'd do that to me, Dohyuk..."
"Right... Even if it's temporary, you're still my supervisor..."
But.
Lee Yena. This woman.
She was enjoying the situation.
Look at her. Her voice had become so sticky!
"Dohyuk... that weapon... it's really huge and heavy... like a club. Your girlfriend must be happy... having a boyfriend with something this thick..."
"No... are you allowed to say things like that at the company...?"
"What does it matter... Everyone does it..."
"What?"
"Our company. Everyone's starving for sex. External dating is banned, after all."
"No... what the hell! Is that even allowed? And it's not just internal dating—external too?"
"Well, you see..."
According to Eve Secret's company rules, dating was completely prohibited during employment. Of course, everyone had their own ways of relieving stress, but if an official relationship appeared on social media or if a secret relationship was discovered, it meant recommended resignation.
Probably, Eve Secret had established this rule so employees could focus entirely on work.
"So... everyone's... starving for men..."
"Assistant Manager, don't tell me the reason they hired me was..."
"...Huh?"
To use me like this? As a toy for the female employees?
Two emotions surged through me at once.
...Actually, that sounds pretty good?
And then reality hit.
Maybe the reality check was stronger because I hadn't been mentally prepared for this conclusion.
I pulled my cock away from her ass.
"Assistant Manager, I suddenly don't want to do this anymore..."
"Dohyuk! I got the back hug concept. It's perfect. Let's move to the main pose with this same tension."
"Assistant Manager..."
"Press closer to the wall!"
It was as if Assistant Manager Lee Yena couldn't hear my voice. She slipped out of my arms and shoved me backward.
"Ah... cold..."
My back touched the drum washing machine. She approached me as I leaned against it, then suddenly hooked one leg over my thigh.
"Senior?!"
Before I could react, Assistant Manager Yena wrapped both arms around my neck and climbed up onto me in one swift motion.
"Hup."
"Whoa?"
With my back against the washing machine, she spread her legs and clung to my hips in a perfect woman-on-top position.
"This is the main concept. The feeling of the woman taking the lead on top of the man."
"Haa... Assistant Manager, this is really dangerous... I'm in emergency mode right now."
"What's dangerous? We're working right now."
Ha, she could say that even while looking at this rocket-like cock of mine? Or was she doing it on purpose?
At this point, I was done holding back too. Supervisor or not...
"My cock... my cock! It's going to get even bigger, I swear!"
I shouted.
Silence fell over the laundry room. When the newbie yelled like that, even Assistant Manager Yena looked startled.
"...Huh?"

Assistant Manager Yena's shocked expression.
...Cute.
Was it okay for a senior to be this adorable...?!
Even the way she furrowed her brows and made a face was...
"Dohyuk... calling it a cock to your senior... that's too vulgar!"
"Excuse me?"
"Watch your language from now on! Otherwise, I'll have to punish you severely."
"Yes..."
Even as she said that, her cheeks were flushed red and her eyes were moist. If anything, I was curious about exactly how she planned to punish me.
Should I say it again?
Maybe she'd punish my raging cock...
"If you don't want to be punished, stay still. We need to show lovers completely entwined."
"Ugh..."
Eventually, Senior Yena pressed even deeper into my embrace. Her petite frame fit perfectly against mine.
In that moment, a thought crossed my mind.
...I want this woman.
A woman who ignited such possessive desire.
Just then, the washing machine switched to spin cycle, and a rough vibration began rumbling through it.
"...Huh?"
The machine's vibration traveled through my back against the washer and transferred directly to our tightly pressed lower bodies.
Brrrrrrrr—
The vibration reached my cock, which in turn stimulated Yena's ass.
"Aah...!"
Assistant Manager Yena's body trembled on top of me.
"No, why did it suddenly start spinning..."
"Hn...!"
"Assistant Manager... should we take a break?"
"No. Stay like this. Your expression is actually coming alive..."
"Aaah... Is this what it feels like? This concept?"
"Mmm...!"
I thought I understood now. This wasn't just some lewd prank between a supervisor and a newbie. If this was a kind of beta test to infuse the company product with soul before releasing it to customers...
"Assistant Manager... what's the name of this product again? Something like liberation...?"
"Oh my, that's right. The product name is Couple Secret Unlock. It unlocks secrets... a product that lets you feel the freshness of a first experience."
"Assistant Manager, I get it now...!"
Secret Unlock.
Just like the product's name, it was revealing the desires we'd been keeping secret from each other. The urge to wildly torment her pussy until her flushed face twisted in pleasure was growing stronger and stronger.
Even Assistant Manager Yena's expression.
Wasn't she begging for it?!
"Dohyuk... I feel strange..."
"M-Me too. So this was the product's intention. An irresistible force..."
"That's right."
This was the power of the underwear made by Eve Secret.
It was incredible.
The relationship between a workplace superior and junior was being completely disarmed!
Soon, her plump Y-zone began grinding and pressing down on my hard shaft. Every time the smooth panty fabric rubbed together, a dizzying pleasure shot up my spine.
"Assistant Manager... wait a second. At this rate, I'm really going to cum..."
"Stop? That's a lie... You're enjoying this so much too, Dohyuk. Why don't you let go of my ass with those two hands first?"
She was right.
Both of my hands were instinctively kneading her bare thighs and ass with greedy abandon.
I could hear the thread of reason snapping.
Special measures? I'd already sung the national anthem all four verses. Even if there were ten verses, my cock wouldn't stop getting excited.
"Cha Dohyuk. During the interview... you wanted to put your fingers in my pussy, didn't you?"
"...What!? What are you—"
She'd caught me.
I had wanted to shove them in and finger her wildly.
"I know everything. I could feel your finger hesitating right in front of the hole as it passed over my pussy. That was the kindest finger I'd ever felt..."
"...Eh?"
"Fine. Dohyuk. Here... you can do whatever you want...♥"
