IF Side Story: Minhi Acquires the Hypnosis App — Part 01: Onee-Shota
Outside the window, the cries of cicadas had begun to announce the arrival of a scorching summer.
“Huuuuh…… it’s so hot…….”
At twenty-four, having given up on job hunting here and there, I had followed Mom and Dad down to the countryside to try farming.
And then…
One night I had a wonderful dream, so I took that good omen and scratched a lottery ticket—and the first-place jackpot landed right in my hands.
All this time I had kept my feelings carefully hidden, but the love I held for my own older brother had piled up and piled up until, before I knew it, I wanted him all to myself.
Even the thought of other people looking at him made my skin crawl.
Whenever we went down to the ordinary market or the village, every single glance the women cast at my brother set my nerves on edge.
Like this… all alone……
The love I felt for my own blood brother, Yoo Junhi, only grew more diseased with every passing day, and I wanted him completely to myself.
If only I’d had the money, I would have locked him away in some mountain cabin and made him look only at me—those fantasies had filled my head for so long. But now, with the lottery winnings in my grasp, I could finally turn every one of those dreams into reality.
“………Phew……….”
Completely unaware of the love burning inside me, my brother was stretched out on the living-room sofa, napping in the breeze of the fan.
“It’s all…… your fault, oppa…….”
You never noticed my feelings, and you kept doing things that tempted me like this. You shouldn’t have.
Without a clue in the world, he was wearing a loose tank top that left his neck bare and a pair of my pants—because he claimed he had none of his own left.
“Gulp…….”
I kept staring at him as he slept.
That high, elegant bridge of his nose, the double eyelids everyone envied, and those smooth, glossy lips that looked like they would burst with juice if you took just one bite.
Soon…… I’ll be the only one who gets to see him like this…….
As long as I used the lottery money to find a place where I could monopolize him—even if it took a little time—everything would be perfect.
So just wait a little longer for me, oppa ♡
Until that day comes, I’ll endure with photographs.
Careful not to wake him, I slipped my phone from my pocket and opened the silent-camera app.
The first time I tried to take secret pictures the shutter sound had startled me, but by now I was an old hand.
Because it was a cheap free app, a bunch of ads always popped up the moment I launched it.
Should I just pay for the premium version while I’m at it?
Five thousand won would kill the ads, but somehow spending even that little felt wasteful.
But who am I?
Goodbye, you trash ads.
Even after taxes, twenty billion won still sat in my account.
So, for the sake of quietly photographing my brother from now on, I paid for the premium silent-camera app.
—Bzzzt~
A short vibration, and then the message that money had left my account……
“!!!!”
Am I seeing things right now??
The twenty billion that had been sitting in my bank account just a second ago had dropped to zero in an instant.
I told myself the message must be a glitch and opened the banking app.
0 won —
The twenty billion that had been in my account was gone.
…………
My mind went completely blank.
No thoughts, no ability to move—I just stared at the balance.
Raising the daily transfer limit to ten billion because of the prize money had clearly been a mistake.
“Ha… hahahaha……….”
I laughed in a voice small enough not to wake my sleeping brother.
My money…….
My brain refused to accept the situation, and at the same time I couldn’t believe this garbage app had sucked my entire account dry.
With trembling hands I unlocked the phone again, half hoping, half dreading, to look at the twenty-billion-won scam app.
Fuck.
The silent-camera app that had been there a moment ago was gone. In its place sat a single app marked with a strange eye.
What the hell is this…… a Hypnosis App?
Where the silent-camera app should have been, an app I had never seen before was installed.
I had no idea what it was.
I had never downloaded anything like it, yet somehow I felt an urge to tap it.
—Ding!
I opened the Hypnosis App that had appeared on my phone, and something lit up on the screen.
Gender
MaleFemale
I didn’t understand why it was asking for gender, but I tapped “Female” to match myself, and a whole new set of screens appeared.
Gender : Female
LV : 01
Select the desired ability, then show the screen to your target.
LV. 00 : Erases the hypnotized state and all related memories.
LV. 01 : Mental Age Adjustment Hypnosis
[ Teens · 20s · 30s · 40s.... ]
LV. 02 : Locked
LV. 03 : Locked
. . .
What the hell is this supposed to be?
It looked surprisingly polished. To use the hypnosis app, it said, just tap an ability.
“Gulp…….”
Twenty billion had just vanished because of this single app, but if—just if—this thing was real and actually worked, I would have paid any amount for it.
Really……
If this truly was a hypnosis app that worked on people, losing twenty billion wouldn’t matter at all.
I looked at my brother still sleeping on the sofa.
“Uuuung……….”
“……”
I still doubted it would work, but I had nothing left to lose.
[ Teens ]
There was only one option I could choose right now, so I selected Mental Age Adjustment Hypnosis.
Executing Mental Age Adjustment Hypnosis.
※ The user is immune to hypnosis.
The app activated. A dazzling, multi-colored eye began to spin on the screen.
I gently shook my sleeping brother awake.
“Uuugh…… five more minutes…….”
“Oppa, wake up.”
“Ugh…… so annoying…….”
The brother who had been dead asleep a moment ago started blinking his eyes open.
“Why’d you wake me…….”
“Just look at this for a second.”
“What is th……….”
“Oppa??”
The moment he looked at the hypnosis app, his words cut off and the light drained from his eyes.
“What…… does it actually work?”
I was fretting that the app might have broken something and left him unable to come back to himself when—
“Uuuuh……….”
“Oppa? Are you okay?”
The lifeless eyes suddenly regained their sparkle, and the way he looked at me punched straight through my heart.
“Nu… nuna…?”
“?!!!”
“Minhi-nuna, what are you doing here?”
“Ugh!!!”
The eyes that had been empty a second ago now stared at me with the bright, round innocence of a little child.
And the instant he called me nuna, I clutched my chest.
“U-ugh!! M-my heart… my heart feels weird…….”
“Minhi-nuna? What’s wrong?”
“S-stop iiiit…….”
The brother I had always called oppa now, thanks to this hypnosis app, recognized me as his older sister.
And……
Hearing him call me nuna made my heart pound so hard I had no idea what to do with myself.
“Minhi-nuna, are you okay? Why are you grabbing your chest like that?”
“Ah… aaa…….”
Really…… this hypnosis app was the real deal……
Losing twenty billion still hurt, but I had gotten something far more valuable in return.
And it even had the power to wipe the current state and all memories clean.
Which meant that no matter what I did to my brother right now, he wouldn’t remember a thing.
“This is the best.”
The corners of my mouth kept climbing; I couldn’t stop smiling.
“Mi… Minhi-nuna… are you okay? Why do you keep laughing like that?”
“Ah… it’s nothing, Junhi. I just thought of something funny.”
“Really? That’s good then, Minhi-nuna.”
The way he stuck close to my side and fretted over me just like when we were little made my womb clench and throb.
“Haaah…… my little brother… Junhi… won’t you come somewhere with nuna?”
“Hm? Where?”
“Somewhere nice.”
“Nu… nuna… this is a place grown-ups go…….”
“It’s fine, it’s fine. Just trust nuna and follow me.”
I dragged my little brother Junhi all the way to a motel on the outskirts of the village.
We were both adults, so no one stopped us; without any trouble I got a room key for a one-night stay.
“Nu… nuna… this place is a little scary…….”
“It’s okay. Nuna’s right here beside you, isn’t she?”
“U… un…… c-can’t we just go home already…….”
“Why are you so worried? Nuna’s right next to you, isn’t she?”
His body was still twenty-five, but his mind had been rolled back to the teens; the motel clearly frightened him, so he pressed himself tightly against my side as he followed.
Heh… hehehe…… g-good… so good I could die…….
Before long we reached the room. I used the key, opened the door, and stepped inside.
It was just like any other motel room—everything you’d expect was there.
—Squeeze….
The moment we entered, Junhi, who had been glued to my side, grabbed my hand tightly.
“Nu… nuna… are you sure this place is really okay?”
“Yeah, I told you it’s fine. Just trust nuna.”
“S… something feels weird…….”
From the second we walked into the motel, Junhi seemed to sense he was about to get fucked here; he kept saying he was scared and wanted to leave, but……
I had no intention of listening.
At the very least I was going to fuck my brother—no, fuck Junhi—senseless.
Nothing more, nothing less.
—Click.
“U-un?? Nu… nuna? Why are you locking the door……?”
“………”
“Nuna…… say something…… why are you looking at me like that…….”
“………”
At my behavior, Junhi began to tremble and slowly put distance between us.
“Nu… nuna…… why… why are you staring at me like that… i-it’s scary… stop joking around…….”
“My little brother ♡ Junhi~ You trust nuna, right?”
“U-un…… I-I trust you… so please let’s just leave… I’m… scared…….”
“It’s okay. There’s nothing to be scared of~ In fact, we’re about to do something that feels really good ♡”
I walked slowly toward him.
“Nu… nunaaa…….”
“Our Junhi ♡ You know nuna loves you a whole lot, right?”
“U-un…….”
I closed the last of the distance, cupped his cheeks, and pressed my lips to the mouth I had coveted for so long.
—Chuuup ♡
“Mm… mmmph!!”
Junhi thrashed as if trying to resist, but there was no way my brother could overpower me.
To punish him for shoving at me and trying to pull away, I kissed him even deeper.
My tongue hunted his, roaming every corner of his mouth so that my trace would be left everywhere.
—Churp ♡ Churrrp ♡
Delicious ♡ Sweeter than any drink I’ve ever tasted ♡
Junhi’s saliva was incomparably sweet.
“Pwah~~ ♡”
“Heh… heh… nu… nuna… this kiss… i-it’s weird…….”
“Our Junhi ♡ How was the kiss nuna gave you?”
“I… it’s weird… it’s just a kiss… but Minhi-nuna’s tongue… kept going inside my mouth and it feels strange…….”
He thought the kiss I had just given him was a simple peck. I wanted to dirty that pure innocence without mercy.
“Want nuna to do something even nicer for you ♡”
“U… uuh…… I-I don’t want to… I feel like we shouldn’t do this, nuna…….”
“Is that so? That’s how our Junhi feels, huh?”
He wasn’t stupid enough to just roll over and have sex, but……
The thought of defiling that purity with my own corruption and rape made me wildly excited; the pants I was wearing were already soaked with juice from looking at him like that.
I shoved Junhi down onto the bed.
“Ugh! Nu… nuna… what are you doing…….”
“You’re the bad one… Every day you walk around looking so lewd and get me all worked up—it’s your fault.”
There was no need to go slow.
I grabbed the pants and underwear he was wearing and started yanking them down.
“S-stop!! I said stop!! Y-you can’t do this, nuna!”
Junhi grabbed my hands, trying to keep his pants from coming down, resisting with everything he had—but the more he fought, the more it turned me on.
“I told you it’s okay. Nuna’s going to show you heaven.”
“N-no, nuna, p-please… don’t do this!!”
He struggled hard, but my strength was greater than his; the pants came off with no resistance left.
“D-don’t look! Don’t look at it!!”
Once the pants were gone, Junhi tried to hide his cock, covering it with both hands.
“Already so excited… Imagining the moment this fiercely resisting Junhi ends up in my arms crying and whimpering… I’m already drooling ♡”
“I-I hate it…… nu… nuna… please… s-stop it…… please… I-I won’t tell Mom… I won’t tell her we came here… or that you saw my… down there… so please…… s-stop…….”
Junhi started sobbing, begging me through tears to stop.
“Ah…… fuck, that’s so hot.”
I began peeling off my own clothes one by one.
“Get hard before I finish undressing.”
I was so worked up I couldn’t stand it; if I didn’t shove that cock into my pussy right now I felt like I’d lose my mind.
“H-hard… I-I don’t know what that is… I-I don’t know… j-just send me home, nuna… please…….”
“Ah, fuck… you’re saying more things that turn me on?”
I threw every last piece of clothing off.
Just how much had his words excited me—my nipples were standing stiff and hard.
“My adorable little brother Junhi ♡ Nuna clearly told you to get hard, but you’re still soft?”
“H… hard… I-I don’t know what that is, nuna… p-please… I’m begging you, please… j-just send me home…….”
“It’s okay. Even if you don’t go home, soon you’ll be under this nuna crying and whimpering anyway.”
Whether he had no interest in my body or his mental age was simply too young, Junhi’s cock was still soft and wilted.
I settled over his legs, gently took that soft cock in both hands, and began to stroke it slowly.
“H-haaah…… th-that… d-don’t… nuna… m-my… peepee…… i-it’s weird… stop… stop touching it… i-it’s weird…….”
“Why? Does nuna’s hand feel good?”
“I… I don’t know… stop touching… my peepee’s getting weird…….”
“Should I really stop?”
“U-un… please stop… I wanna go home…….”
“No.”
At that single word of refusal, Junhi looked up at me with eyes full of despair—and at the same time, under my hands, his cock stiffened.
“Our adorable little brother Junhi ♡ Want nuna to show you a magic trick?”
“I… I don’t want to… I wanna go home, nuna… s-send me home… my peepee’s weird too…….”
“Don’t worry. Nuna’s going to make you feel nice real soon.”
There was no need for more foreplay.
My pussy was already dripping with juice, hungry to swallow that cock; I could feel it twitching and gaping, desperate to take him in.
I rolled my hips slowly, lining my entrance up against Junhi’s cock.
“Nu… nuna… stop iiiit… weird water’s getting on my peepee… i-it’s weeeird ♡”
—Schluuup
“Ha… haaaah ♡ I-it’s in ♡ Oppa’s…… no, Junhi’s cock ♡ is filling up my pussy completely ♡”
I could feel it.
The pain of my hymen tearing was nothing compared to the way the cock inside me turned every bit of that pain into pure pleasure.
“G-good ♡”
Just from the insertion alone, my pussy felt like it had a mind of its own, writhing and squeezing around his cock, while my womb slowly descended, eager to swallow him whole.
“Ha… haaaaah ♡ Nu… nunaaa…… my peepee… it’s squirming… s-stop iiiit… my head’s… going blank… please… s-stooop ♡”
“Hah… hah ♡ This is only the beginning, Junhi.”
—Schlick ♡
My pussy didn’t want to let the cock go; every time I moved, lewd wet sounds filled the room.
“Heh… heuuuh ♡… Nu… nunaaa… don’t mooove…… my… peepee… is getting weeeird ♡”
“Just a minute ago you were saying you hated it and wanted to go home, and now you’re making that filthy face like a little whore ♡ Looks to me like you’re begging to get fucked like a dog ♡”
“Heh… heuuh ♡ I-it stings…… stings…… don’t mooove ♡”
“A cock like yours needs to be disciplined with a pussy like this!!”
—Thwuuump!!!!
“Heuuuuuh ♡!!!!!!!!”
The moment I slammed my hips down onto his cock, Junhi let out a beast-like cry and his back began to arch.
—Spurt!!! Spurt!!!
“H-huuuuh ♡!! My… peepee… peepee is…… c-coming out of it ♡ Heh… heuup ♡”
“Huuuh ♡ Finally…… finally…… it’s inside me ♡”
The dream I had longed for so long had come true.
My brother’s warm, sticky cum was pressing against the entrance of my womb, flooding in thick and full ♡
I hadn’t even moved much, yet Junhi’s climax dragged me over the edge with him.
—Fsssh!! Fssshhh!!!
I sprayed the love juices of my orgasm all over Junhi’s body as he trembled through his first ejaculation.
“Huuuuh ♡ Nu… nunaaa…… it feels…… it feels so… gooood…… ♡”
The same low-mental-age brother who had insisted he hated it and wanted to go home was now pinned beneath me, tongue lolling, saying things that only excited me more.
“This is only the start ♡”
Once the hypnosis wears off he won’t remember a single thing about today ♡
“Nuna’s going to make you experience, drop by drop with her own body, just how many times you can cum today ♡”
I won’t let a single drop go to waste.
From now on your body, your heart, and every last bit of your cum belong to me.
Yoo Junhi—you are mine now.
Completely, entirely my possession.
