The Junior's Morning Lesson

I stepped into the office with my usual greeting.

“Good morning.”

“Seonbae! Why are you so late!”

A cute puppy-like face, petite frame, and long, lush hair that fell just past her shoulder blades. My adorable junior colleague, Gong Jiyun, greeted me alongside a noticeably chillier atmosphere than usual.

“I can be a little late sometimes.”

My usual arrival time of 8:40 had been pushed forward to exactly 8:00 two weeks ago, right after that suspicious app appeared.

“Hurry up and let’s go for morning education! Hurry!”

Gong Jiyun bounced on her toes, tugging insistently at my collar. The way this tiny thing acted made her look like an impatient little rabbit throwing a tantrum.

“Why are you so excited? You’re draining everyone else’s energy.”

“Hehe, out of all the weekdays, morning education time is my favorite!”

Pulled along by Gong Jiyun’s hand, I followed her to a rarely used spot. Our secret place. The place of education. The dusty equipment room.

Creak—

The equipment room door let out an old, weary groan as it shut. Now, inside this cramped space, there were only the two of us.

“Hurry!”

“Yeah, yeah. Lift your skirt first.”

Gong Jiyun rolled up her formal skirt. A pair of adorable light-green cotton panties came into view.

“What’s this? Why are you still wearing them?”

Her clitoris was already peeking out slightly over the fabric, as if she’d been eagerly anticipating this ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠lesson. I tapped it a few times and scolded her.

“Hngh…!”

“You’re a new employee still in training. How can you be wearing panties at the company? Hm?”

“Haah… That’s not it… Seonbae, hngh, wait, my cl-clit…♡”

“How long has it been since I taught you? Forgetting already would be a problem.”

I pinched the now-stiff clitoris between two fingers and rolled it firmly.

“Ah, ah♡ R-rolling it feels good but… please pinch it harder, heeung♡!”

“Who told you to feel good while getting scolded?”

As requested, I gave her clit a light pinch. Her waist trembled violently in pleasure. A wet stain bloomed across her panties, and I could feel her pussy lips twitching and pulsing beneath the fabric. She seemed to have already reached a light climax.

“Haa… Who told you to twitch your pussy lips during education? Because of you, the person giving the lesson is getting turned on.”

A girl this cute was thrusting her hips forward in orgasm, her pussy lips visibly spasming hard enough to be felt through my fingers. It was insanely arousing. I wanted to pin her down right then and there.

“Hngh…♡ Ha, hngh…♡ Haa…”

Gong Jiyun’s eyes had gone completely glassy. Her mouth hung open, drool slipping from the corner. Just having her pussy touched over her panties was enough to put such a blissful expression on her face.

Then, as if suddenly snapping back to her senses, she tried to glare at me with those hazy eyes.

“N-nooo…! Seonbae told me I must take my panties off only in front of you… so I was waiting!”

“Huh? Oh, right.”

Come to think of it, I had said that. Feeling a bit sheepish, I scratched the back of my head and pulled her slender waist into my arms. Gong Jiyun’s small body melted against me with a soft thud.

“I forgot. Sorry about that.”

“…Is saying sorry enough? You’re rubbing your hard cock against my stomach right now…”

I deftly unbuttoned her shirt to soothe her.

“Sorry, sorry. I’ll apologize properly. Forgive me, okay?”

“Seriously… I like it when you teach me hard, but sometimes you could go a little easier… haang…♡”

I sucked hard on her now-exposed breast. Her modestly swollen, adorable tit stretched into a pointed peak.

“Fine. Today I’ll let you choose the education topic, so let it slide. Yeah? I’m your senior, after all.”

“…Hmph. Just this once.”

“Yeah, yeah. So what kind of ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠education do you want?”

Gong Jiyun pouted cutely, pretending she couldn’t win against me.

“Please… lick my pussy.”

The obscene request coming from that small mouth made my cock twitch hard.

“Is that the best during education?”

“Mmm… From our position, yeah, it probably is.”

“You like getting your pussy licked?”

“It feels good just lying back and taking it, it’s super perverted, and it really feels like I’m being properly educated…”

“Perverted? How is it perverted? I need to write it in the education report, so explain in detail.”

Gong Jiyun wiggled her small hand against my chest as she spoke.

“Seonbae, you’re really good at licking pussy. You press down hard on my clit with your upper lip. Your rough tongue goes in as deep as my fingers do when I masturbate, rubbing all the folds inside my walls, drrrk drrrk…”

Ah, this cute junior unconsciously spouting such filthy words… It was seriously turning me on.

“The breath from your nose hitting my pubic bone feels so tingly and perverted… Oh, but my nipples got hard from the cold air. You need to suck them, right?”

“Ah, yeah. I’m supposed to suck them when they get hard. Right. Chuuup—”

I took the sweet-scented pink nipple into my mouth and sucked.

“Eut, ha, ah…♡ Ah, it’s so warm…♡ I-I’ll continue. Um… where was I…”

Gong Jiyun stroked my head, which was buried in her chest, and kept talking.

“And… I don’t know if you realize this, Seonbae, but when you shove your tongue really deep into my pussy…”

“Slurp, chuuup— Yeah. What about it?”

“Ha, aah…♡ At that time… you always, um… how do I say it? The spot where my butt and thigh meet…”

“Slurp. You mean the underside of your ass?”

“Yes, anyway, you grab that spot so tightly it feels like you’re going to crush it and pull me downward… When you do that, my butt spreads open and cold air touches my asshole… making me twitch and shiver all over… That part is really… haat♡ That… that part is seriously so perverted…”

“Chuuup… Oh… Really? I didn’t know. I’ll keep that in mind. I’ll spread your ass more often from now on.”

“Yeees. And while you’re at it, please touch my asshole too… Ah, Seonbae. My left nipple is cold now…”

“Okay, I’ll switch. Chuuup—”

“Haaang♡ Th-thank you…”

Gong Jiyun rubbed the nipple I had just released, expressing her gratitude. The saliva-coated, plump pink bud glistened wetly.

“Anyway… Seonbae licking my pussy is just… way too perverted…”

Well, you’re one to talk.

A girl who got her pussy licked by a company senior who wasn’t even her boyfriend, and then explained every single sensitive spot in such vivid detail. She had no idea how perverted she herself was, yet she praised me for being perverted. My cock was so hard it felt like it was about to burst.

“Ah, Seonbae! Also, when you’re licking my pussy, can you not do that one thing?”

“Hm? What thing?”

“You know, that thing. Um… how do I describe it?”

Gong Jiyun stroked my head, struggling to put her thoughts into words.

“When you’re licking and then suddenly, like a vacuum cleaner, you suck my hole with all your strength—choooop!”

“Yeah, I do that. Why? You want me to stop?”

“Yes! That really makes the person receiving it feel so weird!”

“How does it feel weird?”

“Ah, it’s hard to explain with words…”

I stopped sucking on her breast, knelt down in front of Gong Jiyun, and looked up at her.

“Then I’ll do it now. Feel it and explain while you do.”

“What? No, no…! I told you not to do that!”

“Shhh. I have to write the report, remember? Stay still.”

I pulled down her light-green panties, revealing her pussy. The plump lips paired with soft, neat pubic hair made her look incredibly young. Her folds were already glistening with arousal.

I brought my mouth to her slit.

“I told you clearly, right? Describe the feeling. Got it?”

“Ah…! N-nooo! I really hate that—ha, haat♡?!”

I pressed my lips against her tiny hole like a kiss, then sucked with all my might like a straw. Chooooop—

“O-ohhhng…?! Hng, hoooooooock♡?!”

Gong Jiyun tried to push my head away from between her legs while her hips jerked violently. Her pussy clung to my tongue with wet, obscene sounds, gushing fluids.

“Chooooooooop—”

“O-ohhhock♡ H-aaaaaahng♡ Hngooooooong♡!!”

To signal her to start talking, I smacked her trembling ass sharply.

“Ho, hoooock♡ My pussy inside is, it’s, it’s shrinking so much♡ My belly, inside my belly feels so tight and tingly♡ H-haaaat♡ My womb♡ It feels like my womb is being sucked in♡ S-stop♡ Hooot♡ It keeps, from my pussy, it keeps squirting out, viewwwwt viewwwwt♡ Haaat♡ Ah, haaaat♡! Haaaaaaaahng♡!”

Fluid gushed from Gong Jiyun’s pussy like a fountain. Her hole twitched wildly as she pressed her weight onto my head, hips bucking uncontrollably.

“My p-pussy♡ My pussy is squeezing all by itself♡ Squeezing so tight♡ So tiiiiight♡”

Even so, she faithfully reported everything I’d ordered her to. She might complain, but she was a good girl who listened to her senior well.

“I-I’m gonna cum♡ I’m cumming♡ My pussy’s cumming♡ Hoooooooong♡”

I had trained her to say “I’m cumming” when she climaxed. Her pussy, which had been about to open, only trembled violently under the suction of my mouth as it continued to spray.

“He, hek♡ Hek♡ Heeek♡ I came♡ I came so♡ Please stop, stop licking my pussy…♡”

As requested, I pulled my mouth away from her pussy. Tzzzzzzt— Several silvery strands of saliva and nectar stretched like spider silk between my lips and her slit.

When I looked up at her from between her legs, she was an absolute mess. Her half-lidded eyes had pupils completely blown wide. Her mouth hung slack, tongue lolling out. She looked dangerously fucked-out.

“Aigoo~ Our cute junior still listens to her senior well, huh?”

“He, heh♡ Ha, ah♡”

She still hadn’t fully come back to her senses and could only twitch weakly.

“Here, here’s your reward.”

I slid my tongue into her open mouth and swirled it around.

“Slurp, chuuup, chup… sluuuurp…”

“Haaum… hngum, hngnum…♡”

Even though her mind was gone, she instinctively sucked on anything that entered her mouth like a baby, greedily nursing on my tongue.

“Slurp, chuuup… Haa…”

When I finally withdrew my tongue from her sucking lips, a long string of saliva connected us.

“Hngnum… Haa… Aah…”

Gong Jiyun let out a disappointed sigh. She had already regained some awareness and was looking at me with ecstatic eyes, having been sucking my tongue.

“More… moreee…”

She grabbed my collar and whined. When a beautiful puppy-like girl looked up at me with heart-shaped eyes begging for a kiss, it was impossibly arousing.

“Haa… You fucking perverted bitch… Seriously, I want to shove my cock in your mouth so bad I’m losing my mind…”

“If you want to, then do it… I’ll suck it really well too… Okay? Seonbaeee…♡”

I wanted to more than anything, but it was five minutes before work started. If I took my cock out now, we’d be late.

“I’ll give it to you later. Let’s head back to the office now. Good girl~ Yeah?”

“Hmph… Fine, but don’t talk to me like I’m a child…”

“Yeah, yeah. Come on, let’s go. Oh! You need to take off your panties and bra and give them to me.”

“Ah, right! That was close…”

Gong Jiyun reached under her skirt and wiggled out of her panties, then removed her bra and handed both to me.

“I’ll take these according to procedure. Come to my house on the weekend to pick them up. And don’t show up at the office with your nipples hard like last time, okay?”

“Yes~ Thank you for licking your junior’s pussy~”

Gong Jiyun bowed politely at the waist, following proper procedure. With that, morning education was over.

We left the equipment room. I supported the wobbly-legged Gong Jiyun all the way to the office entrance.

“You’re here.”

“Yep.”

The guy sitting next to me—my coworker and close friend at the company, Park Youngmin—greeted me.

Park Youngmin pointed at the bag on my desk and asked,

“Looks like you came in early again today.”

“Yeah.”

“Why have you been coming in so early lately? What do you do outside the office when you arrive first?”

“Junior education.”

“…For real?”

“Of course it’s real.”

Park Youngmin gave me a dubious look before turning away. To others, I probably looked like a diligent employee devoted to training his junior. But Park Youngmin, who stuck to me often and was quick-witted, was starting to suspect me.

Should I modify him too?

It seemed I needed to pay attention to my surroundings instead of only focusing on conquering women.

I checked the clock.

“It’s nine already.”

“Ugh… I already want to go home…”

Gong Jiyun whined as she walked past. The cute new employee who had stolen the gaze of every male employee from her very first day—Gong Jiyun—was now completely under my control.

What a sweet, abnormal daily life. All thanks to that app…

Two weeks ago. A mysterious app had appeared before me, an ordinary office worker.

The Modification App.

An app that let me edit a target’s inner thoughts and perceptions however I wanted. Thanks to it, a pitiful little rabbit was getting defiled by me every single day.

Who the hell made this app anyway… Hm?

I somehow made it through the day in a daze.

“Good work today~”

“See you tomorrow.”

The moment I got home, I turned on the app.

…What kind of update is this?

I had no idea what changes would occur, but there was no choice. The screen showed nothing but the ‘Yes’ button.

…Yes.

I pressed it. A buffering icon spun in the center of the screen. Five seconds… ten seconds… about a minute passed.

My vision went dark.

.

.

…

.

Just like when I first received the app.

.

…

…

.

Information flowed into my mind.

.

..

…

..

As if it had always been there.

…

.

.

…

Something was ‘modifying’ my knowledge.

…

.

…

Or perhaps.

..

..

Not just knowledge, but something else as well.

…

…

.

.

.

My vision returned.

“…”

I reviewed the knowledge that had entered my head.

Points are generated when I ‘change a target’ through modification.

I opened the shop.

There were only two items listed.

That’s it?

Was the only way to obtain items through gacha?

I opened my user information.

I guess I should try the gacha for now.

It was the only thing I could do with my points at the moment.

Skills first.

“…Oh?”

Just from the descriptions, they all sounded incredible.

But… will they actually work?

I had already experienced the power of the app. There was no room for doubt. Still, the skill descriptions were so sweet they felt unreal.

The numbers had definitely updated. I pulled at the front of my pants to check on my junior.

“Oh…? Oh!”

It had grown. Even though it wasn’t erect, the change was visible to the naked eye.

The skills are real too.

Both Sex Master and Azoospermia were fantastic. Sex Master went without saying, and Azoospermia would let every man’s dream of irresponsible pleasure come true.

There are surgeries, but using a knife is a bit much.

And it was a toggle skill. Perfect.

Next… item gacha.

With sky-high expectations fueled by the skills, I purchased an item box.

Let’s just do one for now.

I scrolled through my contacts. They were sorted alphabetically, so his name appeared quickly.

[Gong Jiyun]

▶[You know?]

▶[Tomorrow’s Saturday]

The read receipt appeared instantly.

◁[—_—]

A simple reply arrived.

▶[What.]

◁[My Saturday…]

▶[I’m also giving up my Saturday]

◁[It’s toward the company!]

Pfft— Her cute reaction made me laugh without meaning to.

A little later, the reply came.

◁[This junior]

◁[End later than]

Just as Gong Jiyun feared, it would definitely end late.

Because I’m going to savor her thoroughly.

▶[Yep]

◁[(crying emoticon 1)]

◁[(crying emoticon 2)]

◁[(crying emoticon 3)]

◁[(crying emoticon 4)]

“Heh.”

I could practically see Gong Jiyun’s sulky face in front of me. I threw myself onto the bed, thinking about the ‘modifications’ I would apply to her.
