Squeak-

    “Good morning.”

    I greeted him habitually as I entered the office.

    “Senior! Why are you here now!”

    Cute puppy-like face, small stature.

    A voluminous head of hair that extends just beyond the shoulder blades.

    A cute assistant greets me along with colder air than usual.

    “It might be a little late.”

    My commute to work was at 8: 40.

    A week ago, the clock was brought forward to 8 o’clock sharp with the appearance of a suspicious app.

    “Let’s go to morning class quickly! Hurry up!”

    The assistant manager, Gong Ji-yoon, jumps around and grabs my collar.

    The little guy acts like this, like a rabbit throwing a tantrum.

    “Why are you so excited, the person you’re with is so excited.”

    “Hehe, I like morning classes the best during the weekdays!”

    Led by Gong Ji-yoon’s hand, he moves to a deserted place.

    Our secret place, our training ground, the dusty supply room.

    Squeak-

    The supply room door closed with a worn-out creaking sound.

    Now, in this secret room, there are only the two of us.

    “Hurry up!”

    “Yeah, yeah. Lift up the skirt first.”

    Gong Ji-yoon rolled up her suit skirt.

    A pair of cute light green cotton panties were revealed.

    “What, why are you still wearing it?”

    As if anticipating the training, her clitoris is already poking out from above her underwear.

    I teased him while patting his clitoris.

    “Ugh…!”

    “What if a new employee in training wears underwear at work? Huh?”

    “Haat… That’s not it… Sun, huh, wait, nose, bean…♡”

    “How long has it been since you taught me? It would be a problem if I forgot already.”

    I grabbed my stiff clitoris and rolled it with two fingers.

    “Ah, ah♡ Gu, rather than rolling it… pinch it, heung♡!”

    “Who feels it while getting scolded?”

    When I gently pinched her clit as she wished, she wiggled her waist in pleasure.

    The vaginal discharge stains her panties and she can feel her vagina bulging through the fabric.

    It seems like we’ve already reached a mild climax.

    “Haa… Who would flinch during training? You’re making the person who’s training you feel bad.”

    This cute girl thrusts her hips forward and climaxes, her pussy twitching enough to be felt by her fingers.

    It’s a crazy situation. I want to pounce on it right now.

    “Huh…♡ Ha, huh…♡ Ha…”

    Gong Ji-yoon’s eyes widen, her mouth falls open, and drool leaks out.

    She looks so happy just by having her pussy touched over her panties.

    Then, the guy suddenly comes to his senses and glares at me with his eyes wide open.

    “Ah, no…! My senior told me to take off my underwear in front of him… That’s why I waited!”

    “Huh? Oh, right.”

    Now that I think about it, that’s what I did.

    I scratch my head in embarrassment and hug the guy’s thin waist.

    Gong Ji-yoon’s small figure fit into his arms.

    “I forgot, sorry.”

    “…Is it enough to just say sorry? Even now, you’re still rubbing your erection against my stomach…”

    He calmed the guy down by unbuttoning Gong Ji-yoon’s shirt.

    “Sorry, sorry. I apologize, let’s get over it. Okay?”

    “Really… It’s good that you educate them diligently, but sometimes you can let them go a little…Haaang…♡”

    I sucked on her breasts that had suddenly become exposed to the air.

    Her cute, moderately swollen breasts stretch out into a spire-like shape.

    “Pa. Today, I’ll change the subject of education to what you want, so skip it. Okay? You’re my senior.”

    “…Chi. Just this once.”

    “Yeah, yeah. What kind of education should I do?”

    Gong Ji-yoon pretends not to be able to win and keeps ticking.

    “Don’t you see… Suck it.”

    The lewd words coming out of her small mouth make me squirm without even realizing it.

    “Is that the best during education?”

    “Yeah… From our perspective, I guess that’s true.”

    “Do you like it when you see it quickly?”

    “It’s comfortable because you just have to quietly receive it, and it’s so wild, it feels like you’re getting a proper education…”

    “Do you have to? How do you have to? I have to write it in the education status report, so tell me in detail.”

    Gong Ji-yoon speaks while fiddling with her small hands on my chest.

    “Senior, you suck really well. You press down on the bean grain with your upper lip. Your rough tongue goes in as deep as your finger when you masturbate, and you rub the inner vaginal folds…”

    Ah, a cute junior who talks dirty without realizing it… I really like it.

    “The breath that touches my pubic bone is so creepy and erotic… Oh, but my nipple is stiff because it touched the cold air. Should I suck it? ”

    “Ah, right. I had to suck the nipples when they were erect, right? Chuuup-”

    I put the pink nipple with its sweet fleshy scent into my mouth and suck it.

    “Ugh, ha, ah…♡ Ah, it’s warm…♡ G, I’ll continue. Uh… Where did I stop…”

    Gong Ji-yoon continues talking while stroking my head, which is buried in my chest.

    “And… I don’t know if you know this, but there are times when you stick your tongue deep into my vagina.”

    “Choot, jooup- Yeah. Why is that?”

    “Ha, ah…♡ That, that time… Senior, out of habit, that… Where is it? The place where my butt and thigh meet…”

    “Chu-reup, what, roughly butt fat?”

    “Yes, anyway, there, huh, huh♡ There… he grabs it so tightly as if he’s going to burst it and pulls it down… and then his butt spreads and the cold air hits his anus… and it, tingles, and it’s creepy… that’s really… haat♡ that, that’s really lewd…”

    “Sigh… Oh… Really? I didn’t know. I’ll have to keep that in mind from now on. I’ll spread my butts often.”

    “Yes, if you’re going to do it, please touch my asshole too… Ah, senior. My left nipple is cold…”

    “Okay, I’ll change it and suck it for you. Chuuup-”

    “Haang♡ Thank you…”

    Gong Ji-yoon rubs her nipples, which she just spit out, and expresses her gratitude.

    The luscious pink nipples soaked in saliva glisten with watery luster.

    “Ah, anyway… It’s really, really wild when you see your senior sucking my dick…”

    ‘Well, you’ll just do it.’

    A bitch who explains in such detail the points she feels while looking at her senior colleague who isn’t even her lover.

    He doesn’t know how slutty he is, and he compliments me on how slutty he is. Seriously, my dick is so horny I could explode.

    “Ah, senior! And, when you suck on a boi, shouldn’t you do that?”

    “Huh? What is that?”

    “There’s that, that. Uh…what’s it called?”

    Gong Ji-yoon strokes my head and tries to express my thoughts in a rambling manner.

    “That, while sucking, suddenly, like a vacuum cleaner, he sucks the hole with all his might! ”

    “Yeah, right. Why? Don’t do that? ”

    “Yes! That’s really, it makes the person on the receiving end feel weird!”

    “How is it weird?”

    “Ah, it’s hard to express in words…”

    I stopped sucking my breasts and knelt down in front of Gong Ji-yoon.

    “Then I’ll do it for you, so explain it to me as you feel it.”

    “Huh? Oh, no…! I told you not to do that!”

    “Sup. I have to write a report. Stay still.”

    She pulled down her pink panties, revealing her vagina.

    The vagina, which looked very young with its plump breasts and soft fur, was already soaking wet and glistening with vaginal fluid.

    I put my mouth on the clam shell.

    “I said it clearly? Tell me how you feel. Got it?”

    “Ah…! Shit, I don’t like that! You really don’t like that, ha, haat♡?!”

    He kisses the small hole as if he were kissing it, and sucks it in like a straw.

    “Oh, huh…?! Huh, hooohhh♡?!”

    Gong Ji-yoon pushes my head buried between her legs and shakes her waist violently.

    The vagina sticks to the tongue and squirts love juice.

    “jjooop-”

    “Oh, ohhhh♡ Haooong♡ Heungooong♡!!”

    He slapped Gong Ji-yoon’s trembling buttocks, meaning to tell her to start quickly.

    “Ho, hooooh♡ Bo, inside of the vagina, it’s getting, oh, oh, it’s getting, shrunken♡ Belly, inside of the stomach is getting, nervous♡ Ha, haoooh♡ Uterus♡ getting sucked in♡ Th, that’s it♡ hooooh♡ Okay, keep, getting the water from the vagina, keep, getting taken away♡ Haat♡ Ah, haaaat♡! Haooohh♡!”

    Water spurts out from Gong Ji-yoon’s vagina like a beverage.

    My pussy twitches wildly, and the guy’s waist jerks as he puts his weight on my head.

    “Look, look at me♡ Look at me, all by myself♡ Look at me♡ Look at me♡”

    Still, he speaks faithfully and faithfully as I tell him to.

    Although he may be a bit noisy, he is a good boy who listens well to his seniors.

    “It’s cheap, it looks cheap♡ It’s cheap♡ Look, it’s cheap♡ Hooong♡”

    I taught you to say ‘I’m going to cum’ when you climax.

    The vagina that was about to open trembled and spurted water because of the suction from my mouth.

    “Heh, heck♡ heck♡ I sucked♡ I sucked♡ Look, stop, look, stop sucking…♡”

    As you wish.

    I took my mouth off the guy’s vagina.

    Tsuaap-

    Several silvery threads run between the lips and the vagina like spider webs.

    When I looked at him from between Gong Ji-yoon’s legs, he looked terrible.

    Through the half-open eyelids, the pupils are visible, focused in the center.

    The mouth is wide open and the tongue is sticking out, giving the face a dangerous look.

    “Oh my~ Our cute junior, you still listen to your seniors well?”

    “Heh, heh♡ Ha, ah♡”

    He still hasn’t come to his senses, he’s just trembling.

    “Okay, let’s get the prize.”

    Put your tongue into the gaping mouth of the guy and roll it around.

    “Whoosh, hoosh, hoosh… hoosh…”

    “Haum… Hungum, Heungnum…♡”

    Like a baby who is absent-minded but reflexively sucks and licks anything that enters his mouth, he sucks my tongue.

    “Choot, choot… haa…”

    As I pulled my tongue out from the lips that were sucking, a string of saliva continued.

    “Hungnum… Ha… Ah…”

    Gong Ji-yoon lets out a sigh of regret.

    The guy suddenly came to his senses and was sucking my tongue with rapt eyes.

    “More, more…”

    The guy grabs my collar and whines.

    A puppy-like beauty looks up at me with her heart-shaped eyes, longing for a kiss. I can’t help but be captivated.

    “Ha… You’re such a fucking bitch… Seriously, I’m going crazy wanting to put my dick in your mouth…”

    “If you want to do it, do it… Me too, I’ll suck it well too… Yes…? Senior…♡”

    I’d love to do that too, but it’s five minutes before work starts.

    If you take out the phone now, it might be too late.

    “I’ll give you some sleep later. Let’s go to the office now. Good job~ okay?”

    “Cheet… Okay, don’t use a childish soothing tone…”

    “Yeah, yeah. Okay, let’s go. Ah! I have to take off my panties and bra and give it to you.”

    “Oh, right! I almost got in big trouble…”

    Gong Ji-yoon puts her hand inside her skirt and slowly takes off her panties.

    Then, she took off her bra and handed it to me.

    “This is the procedure. I’ll take it. I’ll go to work at my house this weekend and take it. Don’t make it look like last time and get caught by the office staff?”

    “Yes~ Thank you for sucking my assistant’s pussy~”

    Gong Ji-yoon bowed as per the procedure.

    With this, the morning training is over.

    After leaving the supply room, he carried the staggering Gong Ji-yoon to the front of the office.

    “Coming now.”

    “It should be.”

    The seat next to me.

    Park Young-min, who joined the company at the same time and is a close friend within the company, greets you.

    Park Young-min points to the bag at my seat and asks.

    “I think you came first today too.”

    “Uh.”

    “Why do you come to work so early these days? What are you doing outside the office when you come home early?”

    “Vice-Advisor Training.”

    “…Really?”

    “Really, then.”

    Park Young-min looks away with a trembling expression.

    To other people, you may appear to be a ‘conscientious employee who works hard at training assistants.’

    Park Young-min, who often hung around with me and was quick-witted, began to gradually suspect me.

    ‘Should I fix this too?’

    Rather than focusing only on winning over women, it seems necessary to look around as well.

    I looked at my watch.

    “9 o’clock.”

    “Ugh… I want to go home already…”

    Gong Ji-yoon whines as she passes by.

    Gong Ji-yoon, a cute new employee who immediately stole the attention of male employees from her first day on the job.

    She is playing in my hands.

    ‘It’s a sweet extraordinary life. It started thanks to the app…’

    A week ago.

    A mysterious app appeared to me, an ordinary office worker.

    Modification app.

    An app that lets you modify the subject’s inner self and perception to your liking.

    Because of that, one poor rabbit gets dirty by me every day.

    ‘Who the hell made this app… huh?’

    Tiring!

    [There are updates that meet the conditions.]

    [Do you want to proceed with the update?]

    +++

    I spent the day in a hurry.

    “Thank you for your hard work~”

    “Let’s go in.”

    As soon as I got home from work, I opened the app.

    [There are updates that meet the conditions.]

    [Do you want to proceed with the update?]

    ‘…What update is it?’

    I don’t know what changes will happen, but I have no choice.

    Nothing appears on the screen except the ‘Yes’ button.

    ‘…yes.’

    I pressed the button.

    A buffering indicator rotates in the center of the screen.

    5 seconds…

    10 seconds…

    About a minute passed.

    Tiring!

    Information flows into my head.

    As if it was the information that existed originally.

    Review the knowledge that has entered your head.

    I went into the store.

    [Random Skill Box] – 500 points

    [Random Item Box] – 100 points

    There are only two items on display.

    ‘Is this all?’

    Is drawing the only way to get items?

    User information was displayed.

    ‘Starting with skills.’

    [Would you like to open 3 random skill boxes?]

    ‘yes.’

    [You have acquired the skill ‘Big and Beautiful’!]

    An additional 3 cm correction is applied to the length of the penis.

    [Sex Master]

    Lv. 1

    Additional minor adjustments are applied to each sexual act.

    [Azoospermia]

    (on/off skill)

    It inactivates sperm, making it unable to impregnate a woman.

    “…Oh?”

    If you just look at the descriptions, they are all like pearls.

    ‘But… will it really work?’

    The power of the app has already been experienced. There is no doubt about it.

    But the skill description is too sweet.

    So much so that it doesn’t feel real.

    First of all, the numbers have definitely been updated.

    Pull up the front of your pants to check out Junior’s appearance.

    “Oh…? Oh!”

    It got bigger.

    It’s a subtle change, though, as it’s before erection.

    Clearly, there are changes that can be observed with the naked eye.

    ‘The skills are also real.’

    [Sex Master] and [Azoospermia] are both very good.

    [Sex Master] goes without saying.

    [Azoospermia] will make every man’s dream come true, his irresponsible pleasure.

    ‘There’s surgery, but… I don’t think going under the knife is right.’

    Even on/off skills.

    It’s perfect.

    ‘Next is… item drawing.’

    I bought the item box with high expectations due to the skill.

    ‘For now… should I just try one?’

    [Would you like to open 1 random item box?]

    ‘yes.’

    Pull down your contact list.

    After a while, a reply came.

    ◁[Just in case]

    As Gong Ji-yoon worried, it will definitely end late.

    ‘Because you have to taste it really thoroughly.’

    It seems like I can see Gong Ji-yoon’s expression as she crouches before my eyes.

    I threw myself on the bed, thinking about the ‘corrections’ I would apply to Gong Ji-yoon.
