My Junior's Education
The doorbell rang—Gong Jiyun had arrived at my house.
Click. “Reporting for duty~”
The small, adorable thing brushed past me as I held the door open. As if she were completely at home, she kicked off her shoes with a cheerful morning greeting.
Gong Jiyun came to my house every weekend for some very thorough “education.”
‘It used to stop at foreplay, but today…’
I casually served her some iced tea.
Slurp— “But why are you still in your pajamas, sunbae?”
Even though she was here for training, Jiyun had shown up in her usual office look.
“It’s my house. What’s the big deal?”
“Still, we’re supposed to be working, aren’t we? That’s disappointing~”
“Technically, it’s your education.”
She’d been whining through text messages, but now she was smiling brightly and cracking jokes.
“Who cares if I’m in pajamas? They’re coming off anyway.”
“Huh? Why would you take them off? Oh, are you changing into something else?”
Slurp— Her expression was utterly innocent. She had no idea what was about to happen to her.
“You don’t have to. It’s just the two of us for the lesson anyway. Make yourself comfortable.”
Ignoring Gong Jiyun as she sipped her iced tea, I opened the app.
Start Modification Mode?
Target: Gong Jiyun
‘Yes.’
Modifying Gong Jiyun’s inner psyche.
The world around me turned pitch black. I had entered Gong Jiyun’s mental space.
Exiting Modification Mode.
My vision returned. In front of me, Gong Jiyun sat quietly, still holding her iced tea. Her eyes were unfocused, as if she were in a daze.
“Hey, hey!”
“...Ah, eh? Yes?”
“Look at you. Still half asleep.”
I naturally slipped off her suit jacket.
“Huh...? Did I doze off?”
“How are you supposed to learn anything like that? You’re not going to fall asleep in the middle of the lesson, are you?”
Before I knew it, her blouse was gone too, leaving only her bra on top.
“Come on~ No matter how educational it is, who falls asleep during sex?”
She reached behind herself and unhooked her bra.
Click—
The moment she undid the hook, I also popped open the button on her skirt.
Looking up at me with those pure, innocent eyes while wearing nothing but white cotton panties and black pantyhose… it stirred something primal and possessive deep inside me.
“Um...”
She must have read something in my gaze. Her face flushed as she covered her chest with both arms.
“Ugh… I-I’ll take the rest off, so… sunbae, hurry up and undress too!”
“Undress? What a naughty girl.”
“Nooo! It’s embarrassing if I’m the only one naked!”
“Heh heh.”
Enjoying her reaction, I stripped off all my clothes. My already massively erect cock appeared right in front of her eyes.
“...Huh? H-huh?!”
Her eyes widened in shock.
“S-sunbae! Why is it so big?!”
“Because you’re turning me on.”
“Nooo! Not that—I mean it got longer!”
Big and Beautiful — +3cm correction
Obviously, a cock growing overnight was impossible. Any normal person would be shocked and suspicious.
“So what?”
“Huh?”
But there was no problem. I had already taken care of that in Modification Mode earlier.
Kim Junyoung’s body may undergo dramatic changes, but she will not find it strange.
“It’s not weird for it to grow about 3cm, is it?”
“Ah…”
Gong Jiyun’s eyes glazed over slightly.
I am a new employee. There are many things I don’t know, so I must learn diligently.
Kim Junyoung is my senior. I must receive training from Kim Junyoung.
I will not question Kim Junyoung’s lessons.
“Didn’t you know? If you keep touching a cock every day, it grows a little bit.”
“Uh… um…”
“You’ve been sucking it every day during your lessons. Of course it would get bigger.”
Gong Jiyun’s eyes refocused.
“I-I see… I didn’t know that before.”
“Good. Now stick your ass out. Time for your lesson.”
“Ah, wait a second. Let me take off my stockings and panties first.”
“No. Leave them on.”
“Huh?”
I led Gong Jiyun to the bed and made her get on all fours with her ass raised. Her cute little butt was wrapped in white cotton panties, and glossy black stockings clung to them.
“Pay attention. This is how you use pantyhose during sex.”
I tore the crotch of the stockings apart.
Riiip—
“Ahhn~”
Then I pulled her panties to the side. Her soft, downy pussy lips, already soaked and glistening with arousal, were revealed.
“Whoa… fuck…”
Looking at those tightly closed, baby-like folds, I was reminded all over again how young she was. This was the perfect little pussy for a cute, innocent new hire who had been the subject of every male employee’s dirty fantasies since the day she started.
‘Look at how pretty her pussy is… I’m so fucking hard right now…’
The fact that this girl was presenting her ass to me made me insanely aroused.
“Hm? You’re already wet.”
“B-because it’s before the lesson! It’s supposed to get wet!”
“Who said that?”
“You did, sunbae…”
“I never said anything like that.”
I slid a finger into her narrow hole. Thick, scorching wetness enveloped it.
Squelch—
“Haaah…!”
Her hole had once been as tight as her small frame suggested, but now it easily accepted two fingers. It had been thoroughly trained by me.
Her elastic new-employee pussy recognized its owner and squeezed my fingers with wet, rhythmic pulses.
“You’re not here for a lesson at all, are you? You just want your pussy stuffed, right?”
“Hnnng… shut up!”
Gong Jiyun turned her head and snapped at me. Her embarrassed reaction was like a tiny animal trying to look threatening.
I stirred her tightly pressed inner walls without mercy. The bumpy texture of her vaginal walls dragged against my fingers.
‘If I put my cock in here… holy shit…’
Those vivid folds would scrape against my glans instead of my fingertips. My cock throbbed painfully, on the verge of exploding. I never knew fingers alone could make me this horny.
Squelch, squish, slurp—
“Ha, huaa… mmm… hnn…♡ Huh…? Mmm…♡?”
Suddenly, Gong Jiyun lifted her head with a confused expression.
Slurp, squelch, schlick, squish—
“Haaang… haa, haaahk♡?! S-sunbae, your fingers today… haaang♡”
Schlick, squelch, squish—
“Hnn, kup, haaahk♡?! S-something’s wrong! Sunbae’s hand, haaht♡?! Y-your fingers! It feels so gooood♡”
Unlike usual, Gong Jiyun’s pussy was writhing wildly, greedily swallowing my fingers. The amount of juice was the same. It hadn’t even been a minute, yet she was already flooding.
The wet sounds grew increasingly obscene.
Schlick, squish, splat, splat—
“Ha, ho, hoook…♡ Why, why is it like this! Your fingers, hnnk, haaaahk…♡ Haahk♡ I-I’m going crazyyy…♡”
Soon her hips began to shake violently.
“Hooooook…! Hook♡ Sunbae, I think I’m gonna— haaaahk♡ I’m c-coming! I’m coming, hoooooook…♡!”
Her pussy juice splattered all the way to my face. Even though I had stopped moving my fingers, her hole kept twitching and making wet noises on its own.
Squish, squelch, squish, squelch—
“Haaaaah…♡ Ha, haaht♡ Haaaaahk…♡”
Her pussy drooled thick fluids while greedily chewing on my fingers. The inside of her scorching hot cunt felt like it would cook my fingers alive.
“Wow…”
Someone could probably cum just from the sensation of these fingers. The sight was that lewd and arousing.
‘So this is the power of a Level 5 skill… It’s no joke.’
Sex Master Lv. 5 (Master Level)
(Passive Skill)
Applies absolute-level correction to all sexual acts and performance.
This was the Level 5 version of the skill I had drawn yesterday. The reason I could raise it straight to Level 5 was thanks to an item.
Awakening
One-time use item. Temporarily raises one designated skill to Master Level for 6 hours.
‘I used it this morning.’
Smack, slurp, squish, squelch…
“Haaahk…♡! S-stop! T-take it ouuut♡ Take your fingers ouuuut♡!”
I had already stopped moving my hand. Yet her pussy was convulsing, chewing on my fingers all by itself. And she was cumming again from it.
“I’m going crazy♡! Take it ouuut♡ I’m coming! I’m coming again♡ Take it out! Take iiiit♡!!”
She looked like she was struggling, so I decided to pull my fingers out as she wished.
But.
Sluuurp… The moment my fingers tried to withdraw, the entrance of her hole clamped shut. Then from the inside, it clung to my fingers like glue.
“Huh? W-what the hell?”
It was like taking a mold with silicone—her pussy stuck to my fingers with zero gaps. Then it started sucking my fingers deeper.
“Haaaaaaaahk♡! Take it ooooout♡ I told you to take it ooooout♡ I’m coming…!!”
“Okay, okay.”
I yanked my fingers out by force. The pussy lips that had been biting down on them stretched out like a woman giving a blowjob—juuuuuurp—before finally letting go.
“Huaaaaaaaaang♡ Don’t pull it out! Don’t pull it ooooout♡ Stop♡ Sto— hnngk…?!”
Gong Jiyun’s waist jerked up and down so violently it looked dangerous. Spurt! Spluuuurt!
Her pussy kept shooting out fluids, but none of it leaked out. The thick entrance was clamped so tightly around my fingers that there was no room for the juices to escape. Instead, I could feel the sticky inner walls inside her twitching cunt greedily milking my fingers, squirting thick girl-cum all over them.
“Holy fuck, this is insane…”
Her pussy was incredibly hot, but Gong Jiyun’s body was shaking so hard it looked like she might pass out, so I quickly pulled my fingers free.
Sluuuuurp—pop!
“Guh♡ Guk♡ Oh, ohk♡”
With a satisfying popping sound, my fingers came out. Gong Jiyun couldn’t even make a proper sound, as if the breath had been knocked out of her. She just twitched like a freshly caught fish.
“Whoa… fuck…”
Her hole opened and closed as if lamenting the loss, greedily chewing at the empty air.
Squish— squish— schlick—
“Heh♡ Ohk♡ Guk♡ He, heooook…♡”
It was an unimaginably lewd sight.
“Huu…”
My cock throbbed so hard it felt like it would burst. My throat was dry. Blood rushed to my head, creating unbearable pressure.
What would it feel like to put my cock in there?
“Hauu…♡ Hoo… Haa…♡”
At some point, Gong Jiyun’s upper body had collapsed onto the bed. Only her trembling ass remained raised high toward me.
Inside the hole that kept opening and closing with wet schlicking sounds, I could see a thin, perforated membrane.
Her hymen.
“…”
She was still panting, unable to fully shake off the aftershocks of her climax. Spurt, squirt— her pussy continued to sporadically shoot out small streams of juice.
Even so, I couldn’t hold back any longer.
Schluuurp—
“Haa… hnn…! Hnn♡ Huh…?”
I pressed the head of my cock against her entrance.
“Hnn♡ Ha, w-wait…”
I pushed my cock into her hole. No—her hole sucked my glans in.
Schluuuuurp—!
“Ugh, ah… huaa…?”
The moment I entered Gong Jiyun, I couldn’t help but let out a groan of pure amazement.
“Holy… fuck…”
Her pussy was devouring my cock.
“H-hauu♡?”
The soft, wriggling inner walls clung to my shaft with no gaps whatsoever. Despite being slick with her juices, the suction and stickiness were like a slime toy stuck to a wall. When I twisted my hips once, the tightly pressed vaginal walls pushed back elastically, sending dizzying pleasure through me. I wasn’t joking—my head actually spun.
“What is… this… hnnng…♡?”
Gong Jiyun’s hips twitched intermittently. She seemed to have already had a light orgasm. Her mind was flailing, unable to process the sudden surge of pleasure.
“Hoo, i-inside♡ my belly♡ My beeeelly…♡ It’s touching…♡ What is this…♡?”
“Hurk…! Fuck, pussy, stay still for a second! I’m gonna cum— w-whoa…!”
“Huaaaang…♡? C-cum…? Cum…?”
“Y-yeah. If I cum inside, it’ll be bad, right? So just stay still— hurk, ugh…! Hey, hey!”
Gong Jiyun began grinding her ass left and right in slow, sensual circles. Her plump pussy lips and ass cheeks rubbed against my pubic bone, smearing thick fluids all over it.
“I wanna cum…♡ I, I… wanna cum with my pussy…♡ It feels so good… I’m gonna cum…♡”
Her speech was slurred and her sentences broken. It looked like her mind still hadn’t fully returned. She was simply following her instincts, masturbating with my cock.
“Heuu♡ Inside♡ Rub it… rub it♡ Inside, churn it up…♡”
It was too late to pull out. I could feel the semen already rising all the way to the base of my cock. If I pulled out now, the stimulation alone would probably make me cum.
‘Wait… can I even pull out?’
Or was her hole just so sweet that I was rationalizing it? I didn’t know. My head was going blank from the urge to cum.
‘The Azoospermia skill is an on/off toggle… When it came out of the box… was it on? Or off?’
Like an idiot, I had only been happy about getting the skill and hadn’t checked the important details.
“Hey! Stop— hup— seriously stop! This is really bad! I’m gonna cum! You’ll get pregnant!”
“Cum…? Cum… I’m, I’m gonna cuuuuum…♡ Hek♡ Heeek♡”
Even when I used every ounce of strength to pull my trembling hips back even a tiny bit, this insane pussy would immediately suck me back in with a loud schluuuuurp—.
It felt so good I thought I would lose my mind.
“E, hek♡ T-this♡ Here♡ Riiight here♡”
Gong Jiyun, who had been grinding her ass, seemed to have found a spot she liked. She kept rubbing that exact place against my glans. Her soaked pussy lips slapped wetly against my pubic bone—plap, plap—while she used my cockhead to furiously scratch the itchy spot deep inside her cunt.
“Hoo, heeeng♡ Here♡ Right here♡ This is where I’m gonna cum♡”
“Hey, hey! Haa, huuurk…!”
In the end, I couldn’t hold back.
Spluuuurt! Spluuuuurt— Splurt! Spluuurt!
“Hoooooooot♡!! W-what is thiiiiis♡ It’s so warm, hoooooooong♡”
“Fuck— hup, hak…!”
Her round, donut-shaped cervix latched onto my glans like a suction cup. Then, like a straw, it sucked greedily at my urethra, milking out every drop of semen.
‘How the fuck can a human pussy—’
Sex Master wasn’t me. It was this pussy. Was this hole a legendary treasure? Or was it the effect of my Sex Master skill? If a man was truly skilled, could a woman’s body become this lethally lewd in response?
‘My cum… is being sucked out…’
I had never experienced such an intense ejaculation in my life. I leaned over her small back and savored the lingering pleasure of my climax.
‘…Hm?’
Then I felt something flowing down my thighs and balls. When I looked down, her pussy was still gushing. Gong Jiyun’s legs were trembling violently.
“Heh♡ Ho, hok♡ Hoo…♡ Uu…♡”
“…Gong Jiyun?”
No answer. Only intermittent moans. She was still lost in the waves of an overwhelming orgasm.
Throb— throb—
“Hii♡? Huu♡?!”
My cock, which hadn’t softened at all, throbbed inside her. In response, her waist twitched.
When I gently pinched and twisted her clit,
“Hiiiiiiiooot♡ C-clit! My cliiit♡ Haaaooong♡”
Like flipping a switch, her pussy—which had been starting to calm down—began to writhe wildly again. It chewed on my cock with wet, greedy contractions.
‘Good. I can hold on now.’
Thanks to cumming once, the sensitivity of my cock had dulled a little. I wouldn’t end up in that pathetic state of cumming without even a single full thrust like before.
I began pistoning in earnest.
“Haaaaaaaahk♡!!”
