The Upperclassman’s Brutal Lesson
The moment I stepped into the break room, Lee Jin was already glaring at me like I’d kicked her dog.
“Stand against the wall.”
“Huh? The wall? Like this?”
I did as she said and leaned back against the wall, relaxed and easy.
“Assistant Manager Na. You humiliated me yesterday, didn’t you?”
“Humiliated you?”
Was getting your tits sucked really humiliation?
“Yes. So I’m going to do the same to you.”
“......”
Arms folded, she stared me down and spoke in a low voice.
“You saw my breasts yesterday, so take your dick out too, Assistant Manager Na.”
“......”
What the hell is she talking about?
“Can’t you hear me? Take your dick out, Assistant Manager Na.”
“What?”
“You saw my breasts, so isn’t that only fair?”
“No, it isn’t. You showed me your breasts, and I’m supposed to show you my dick?”
“That’s... well... that’s...”
She looked flustered for a second there.
I snorted and undid the buttons on my shirt.
“Fine, then I’ll show you my chest too. Go on, look all you want.”
“......”
She puffed up her cheeks, looking offended now for some reason.
“Since when are a man’s chest and a woman’s chest the same?!”
“What’s so different about them? Here, touch it and suck on it. Then you’ll know what it feels like.”
Her eyes sharpened.
“Fine. I’ll humiliate you too, Assistant Manager Na.”
Slowly, her hand reached out toward my chest.
The instant her soft fingertips touched my skin, a jolt of pleasure ran through my entire body.
“Ngh...”
The feeling caught me off guard, and a sound slipped out before I could stop it.
“Oh my, what’s this? I only touched your nipple a little, and you’re already reacting~”
She grinned, clearly enjoying my embarrassment.
“Wow, so even a guy’s nipple gets bigger when you touch it...”
Every time she toyed with the nipple, a strangely delicious shiver rippled through me.
She leaned in closer and closer.
I could feel the heat of her breath against my chest now.
“So this is what a man’s nipple looks like...”
She studied my chest with intense concentration.
“Lee Daesik, is this your first time seeing a man’s chest?”
“Yeah... this close, anyway.”
After studying my chest for a while, she slowly opened her mouth.
And then I felt it—wet, soft, and warm.
Churrrp... chuuup... smack.
She started sucking on my nipple with her mouth!
This feeling was...
It was nothing like the way Ji-hye and Hanna had sucked me while we were fucking.
“Mmm... tasty... churrrp... Assistant Manager Na... smack... so this is how it felt when you were sucking my breast... smack smack...”
As she rolled her tongue and sucked, waves of pleasure kept crashing into me.
And then, at that moment—
I felt the warmth of her hand on my dick.
She was touching me through my clothes, but even that was enough to send a fierce current of pleasure through my body.
“Churrrp... Assistant Manager Na... while you were... chuuup... sucking... you touched my pussy too, right?... smack...”
She kept sucking my nipple while stroking my cock, and my dick swelled up like crazy.
“Smuack... Assistant Manager Na’s dick... chuuup... it’s getting bigger!”
She seemed fascinated, because her fingers grew bolder and bolder.
Ngh... shit... at this rate I’m gonna cum...
Her breathing turned rougher and rougher.
Her tongue moved faster.
And her hand, too, became more aggressive.
Then she murmured through the sucking, “Churrrp... Assistant Manager Na... your dick... chuuup... it’s getting hotter and hotter.”
The strange new stimulation pushed me closer and closer to climax.
And I couldn’t hold it back anymore.
Blrrrt!— blrrrtt!— blrrrt!
In the end...
Semen burst out of my dick and soaked through my underwear and pants.
“Gasp! Assistant Manager Na... your pants... they’re wet! This... don’t tell me—”
Lee Jin stared at my pants with a shocked look on her face.
Ah... damn, that’s embarrassing... I really got humiliated for real.
She kept staring at my pants.
“Assistant Manager Na~ how does it feel? Getting humiliated like that? Heehee.”
She looked at me with a laugh full of triumph.
How does it feel? Fucking amazing, that’s how.
But I didn’t say that out loud.
She wore a satisfied expression.
“Assistant Manager Na, if you’re late again in the future, you’re going to pay for it. Understood?”
“Yeah, got it.”
Looking like she’d won something, she turned away.
“Then I’m off work. Thanks for your hard work.”
Apparently in a great mood, she waddled her hips as she left the break room behind.
Should I tell her to show me her ass next time?
Doing this at work instead of in the comfort of home was strangely exciting.
Anyway, my underwear and pants were both soaked, and the sticky mess was really bothering me.
I took a new pair of underwear and my work clothes out of Inventory, then stuffed the wet ones inside.
Having Inventory really was useful in all sorts of ways.
I quickly straightened up the break room, then hurried back to my post.
And just like nothing had happened, I calmly went back to work.
All the while I kept stockpiling the items I needed into Inventory.

Before I knew it, lunchtime had arrived.
And right on schedule, Brother Daehan came by my station.
“Na, let’s go eat.”
“Yes, sir.”
I headed to the cafeteria with him.
“Na, how’s it going? Did you try the method I taught you?”
Brother Daehan had coached me on how to get closer to the women workers.
“Yes. Like you said, I think we’ve gotten a little closer.”
“Oh... already?”
We had, after all, already sucked each other’s breasts, so I guess that counted as getting close.
“Yes, but we didn’t get very far.”
“Ha, ha. Don’t worry. If you keep approaching them little by little, they’ll open up eventually.”
“Yes, sir.”
“Right, don’t rush it. Women pull away the second they feel pressured.”
Pressure, huh...
Would she get pressured if I asked to see her pussy next time?
We picked up our trays and took seats at an empty table.
And once again, I heard that familiar male voice.
“Yo~ look at these gentlemen~”
Lee Daesik was coming over.
“Hey, why the hell do you keep ditching your own team to eat with us?”
“Because it’s fun.”
“Fun, my ass.”
Daesik laughed as he said it, but the laugh sounded bitter somehow.
“Hey, Na. You still not greeting your big brother today?”
I nodded slightly in greeting.
“Hello.”
Lee Daesik looked unhappy with that.
“Tch. That guy, seriously...”
“Hey, why do you keep giving our Na a hard time? Do your guys even say hello to each other?”
Brother Daehan stepped in to back me up.
At his counterattack, Daesik flinched and looked flustered.
“Of course they do!”
“I don’t see them bowing their heads when they greet people.”
“I said they do, didn’t I! Geez. Just eat.”
Apparently he didn’t want to argue any more, because he shoved food into his mouth.
Was he really getting isolated?
Since most people at this company just did their own jobs, people on the same team weren’t even close.
They basically just said hello and that was it.
Unless someone made an effort, there was no real way to become close.
“Daesik, I heard from our girls that there’s some lousy bastard in the transport team?”
Daesik stopped mid-bite.
“Huh? No... no, there aren’t any like that....”
He said there weren’t any, but his face said otherwise.
“What, that guy?”
Following Brother Daehan’s gaze, Daesik turned his head.
After checking that direction, he shoved his spoon back into his mouth.
“I said no. Just eat.”
Daesik began eating in a panic.
I looked where Brother Daehan had pointed, too.
A group of workers was heading off to dump trash.
And among them was a man with a particularly harsh face.
Is that him?
He looked over 180 centimeters tall, and he seemed strong too.
The man’s eyes suddenly met mine.
He stared as though he wanted to devour me alive.
“Hey! Na, stop staring and eat!”
I heard Daesik’s low, urgent voice.
“Yes, sir.”
I went back to eating as he told me.
“Daesik, why are you so freaked out about that guy?”
“What? Hey, you fancy little bastard. Do you think I’m like you? Freaked out? Who’s freaked out!”
“If you’re not, then you’re not. No need to get so worked up.”
“Whatever. Just eat.”
Looking at Daesik now, he really did seem rattled.
A forty-four-year-old man getting intimidated by someone who looked younger than me?
The fact that I was even interested in that sort of thing meant I really had changed.
I’d never have cared about this before.
***
After lunch, the work period continued.
I kept working hard, faithfully filling Inventory with items.
The space in Inventory wasn’t very large, so it wasn’t easy to decide what to keep.
It was hard to tell what was truly necessary.
Still, the hours passed quickly as I kept working.
Count the items left, enter the number. Count again, enter again.
That was all I was doing, and before I knew it, it was already time to clock out.
“Na, looks like Lee Daeri’s late again today?”
Brother Daehan tapped my shoulder.
“Ah, yes, sir. She’ll probably be here soon.”
“Right. Since you said you two got closer, try having a deeper conversation.”
“That’s what I’m planning too. You go on ahead.”
“Alright. Good work.”
Brother Daehan left first.
And the other workers were finishing handoff and heading out as well.
A deeper conversation, huh...
Ten minutes passed.
Twenty.
And then the shameless one showed up thirty minutes late today.
“Assistant Manager Na~ I’m here. You can clock out now~”
Seeing her complete lack of remorse, I really did think a deep conversation was in order.
“You’re thirty minutes late today?”
“Sorry~ Assistant Manager Na. So do I need to pay the price again today?”
She smiled brightly as she said it.
Her expression was completely different from yesterday’s.
“Of course you do, don’t you?”
“Got it~ Then, break room?”
“Yeah.”
“Okay~”
She led the way to the break room.
Her hips swayed with a cheerful little bounce.
Click.
As we stepped into the break room, Lee Jin was already leaning against the wall.
Without my even saying a word, she was unbuttoning her shirt.
Thump.
And out popped her delicious-looking breasts.
As expected, her nipples were already standing stiff and hard.
“Here, Assistant Manager Na. Suck as much as you want~”
This little brat... is she enjoying this?
I looked at the tempting breasts, but I didn’t move to suck them right away.
“No.”
She looked startled at my answer.
“Huh? No?”
“You were thirty minutes late today.”
“So...?”
“Breasts aren’t enough.”
“......”
The smile vanished from her face.
Her voice trembled when she spoke again.
“Then... what?”
I slowly looked down at her pussy.
Realizing where my gaze had gone, she panicked and shouted, “Assistant Manager Na!!! Where the hell are you looking right now?!”
She quickly covered herself.
I looked at her with my eyes wide and said quietly, “Did you forget that you have to pay the price?”
“That’s why I... took my breasts out...”
“That was when you were twenty minutes late. Today you were thirty minutes late.”
“That’s... ridiculous...”
She shrank back little by little, her voice growing smaller too.
“Really? Then should I report this to the team leader? You already had your breasts sucked, so you’d feel wronged, wouldn’t you?”
“......”
She went silent.
It was obvious she was thinking it over.
Then...
As if she’d made up her mind, she slowly opened her mouth.
“Then... this time, where are you going to...”
“Where else? You know perfectly well.”
When I looked back down at her pussy, she shrank even more.
“Fine... but... here... is a little...”
“You touched it with your hand yesterday too.”
“That was... over my clothes...!”
“Exactly my point. Through clothes or not, what’s the difference?”
“......”
Even though I’d touched her over her clothes, she’d still sprayed everywhere.
Which meant the pleasure felt the same whether fabric was in the way or not.
As she kept hesitating, Hanna’s face suddenly came to mind.
Hanna, blushing and sticking out her ass because she was nervous about it being her first time.
“If looking at my face is too embarrassing, then just turn around and stick your ass out.”
“......”
“Fine. Then hurry up and finish it.”
“Got it. Don’t worry.”
Slowly, she turned to face the wall.
And I walked up to Lee Jin.
The moment I reached forward to undo the button on her pants...
Lee Jin trembled all over.
Before I knew it, I’d ended up hugging her from behind.
“Assistant Manager Na... what... are you doing...”
“What do you mean? I’m undoing your pants button.”
“.......”
Feeling the shape of her ass through her pants made my cock begin to swell.
And before long, she felt it too.
“Assistant Manager Na... there’s something... hot against my butt...”
“When people are pressed together like this, body temperature goes up.”
“Is that so? Then hurry up and finish... my body’s getting weirdly hot...”
“Alright.”
I undid the button on her pants.
Click.
Then I slowly pulled them down.
As the pants slid lower, her ass gradually came into view.
And on that ass was a very cute pair of panties with heart patterns on them.
