Hypnotized Little Sister - Kim Jiwon's Side Story
Hey? I'm Kim Jiwon. My name doesn't really matter, though. Lately, people call me by nicknames more than anything. Like "cum pig" or "perverted little sister." Honestly, it doesn't feel great being called that, but I can't go against my brother, so I keep a straight face. Huh? Why can't I defy him? Because it's common sense in every family that a little sister absolutely obeys her big brother, right? Everything my brother says is right. Everything he does is right. So if I feel any dissatisfaction toward him, that's my fault. Yeah. There's no way my brother could be wrong. I live a life like any ordinary little sister out there—getting horny for her brother. The first thing I do when I wake up in the morning is suck his morning wood. Of course, it's just what a little sister has to do. Guys naturally get erections in the morning, don't they? That's so their little sisters can suck them off—we all learned that. A little sister's body exists to be used by her brother. Common sense.
Oh, but my case is a little special. I'm not just serving him sexually—I'm a perverted little sister who gets horny for her brother and loves him as a man. It might seem weird for a sister to love her brother like that, but I'm so head over heels for him that I'd even commit murder if he asked. Of course, I wasn't always like this. Back in the day, I hated his guts. I didn't even call him "brother"—I despised him that much. Why? Because he stole my panties. I thought he was the worst pervert alive and even tried to report him to the police. Mom begged me not to, so I barely held back, but I didn't see him as human anymore. I even lied to people around me, saying I was an only child. Then, about a year ago, he hypnotized, brainwashed, and trained me as revenge. He twisted my body and mind into something perverse. Now, when I smell his scent, my whole body floods with arousal hormones, and I can't feel even a shred of attraction to anyone but him. To me, every human except my brother looks like cockroaches or ants. If he ordered it, I'd commit mass murder without hesitation. Anyway, point is, I spend about six hours a day fantasizing and masturbating about him.

The first place I head when I wake up is my brother's room. My target: the closet. I pull out his panties, flip them inside out over my face, and inhale deeply.
"Hngh~♡"
That intoxicating scent. My legs go weak, and I collapse to the floor.
"Any girl who smells something this arousing has no choice but to become a slave...."
My brother is the ruler of all women. How lucky am I to be under his dominion?
I tucked those panties inside mine and headed to university. Every step made the fabric rub against my pussy—it was so exciting. I had to masturbate three times on the way. In the taxi, on a park bench, and right in front of the university gates. Of course, masturbating when you're horny is common sense, so no one batted an eye.
"Why are you so late?"
My college classmate Yuri grumbled. She was popular for her curvy figure.
"Sorry, sorry. I was wearing my brother's panties and got so horny I had to masturbate."
I lifted my skirt to show her his cum-stained boxers. Yuri stared at the soaked men's underwear and nodded.
"Oh, got it. Jiwon, you're the kind of perverted little sister who can't live without her brother, so it's unavoidable."
"Yeah. I'm such a pervert—I can't help it. Even on the way to school, his panties are too much."
Everyone around me already knows I love my brother. He ordered me to tell them. I had to confess to all my friends that I'm a one-sidedly obsessed perverted little sister. By the way, all my cute female friends have been fucked by him at least once. Yuri got her tits sucked because of her big chest. At first, they were shocked, but after he hypnotized and trained them, they all accepted it naturally.
"We're gonna be late for class. Hurry."
We rushed off. By the time we reached the classroom, the lecture was already in full swing. Of all people, it was the notoriously strict Professor Choi Sujin, so we tensed up as we entered.
"Sorry for being late."
"Miss Kim Jiwon. Miss Yuri. Why are you so late?"
Choi Sujin pushed up her glasses and scolded us. In her thirties and already a professor, she was known for being nitpicky and inflexible. That's probably why a pretty-faced woman like her was still unmarried. Rumor had it she gave zero credit for unexcused tardiness. But no worries this time—we had a valid reason.
"Sorry. I was wearing my brother's panties on the way to school, got horny, and had to masturbate."
The irritated students, annoyed at the interruption, calmed down once they heard my excuse. The problem was Professor Choi Sujin's reaction. She looked stunned and, bizarrely, started yelling.
"W-what did you just say, Miss Kim?"
"? Pardon?"
"Did I hear that wrong? What did you say? Repeat it."
"I didn't say anything special..."
"Repeat it!"
I said the exact same thing again. Just about getting horny from my brother's panties and masturbating—totally everyday stuff. Then Professor Choi Sujin turned ghostly pale and red-faced, throwing a hysterical fit.
"What kind of outrageous thing is that to say in a public place like this! Are you on drugs or something?! Even as a fellow woman, that's sexual harassment! No—it's an insult to every student in this class! Get out of this lecture hall right now! There will be university-level disciplinary action for your problematic statement, so reflect on yourself and wait!"
She slammed her pointer like a whip against the blackboard and bellowed. I exchanged glances with Yuri and sighed helplessly.
"Professor.... This won't do."
We strode forward and grabbed Professor Choi Sujin, pinning her in place.
"What is this?! Let me go right now! Everyone, help me!"
The students stood and approached at her plea, but they betrayed her expectations—instead helping us restrain the professor. Now she was even sniffling back tears.
"Don't worry, Professor."
This happens sometimes. We pulled out our smartphones and opened the only app installed: the Hypnosis App. Everyone in the world has it. My brother ordered it.
"Look at this."
"What are you doing... Have you all gone mad?"
Professor Choi Sujin tried desperately to escape, but she ended up staring at the screen. Her furious eyes softened into something kind and docile.
"Was I... out of hypnosis just now?"
"Yeah. You were acting really weird. Scared us."
"Sorry. I can't believe I showed such an ugly side...."
She stood, a bit embarrassed. The students returned to their seats. I still had words for Professor Choi Sujin.
"You know how embarrassing and wrong it is to be out of hypnosis, right?"
"....Yes."
She looked like a scolded child, face full of shame. Of course. Any sensible adult knows you have to stay hypnotized. Sometimes people slip out, but self-hypnotizing with the app is common sense for civilized people. Neglecting that.... She suddenly seemed repulsive. Like a rebel defying my great brother's rule.
"If you know you did wrong, you need to show some self-reflection."
"H-how should I do that?"
I ordered her to strip and masturbate on the podium. She let out pig-like squeals, convulsing until she climaxed.
"I-I swear I'll never be so stupid as to slip out of hypnosis again! Buhee! Buhee!"
This happens occasionally, so the students ignored it. The boys had all their sexual urges castrated by my brother anyway, and the girls wouldn't get turned on by another woman. After class, Professor Choi Sujin thanked me.
"Miss Kim. Thank you so much today. If it weren't for you, I don't know how embarrassing it would've gotten."
"No big deal. Hypnotizing someone who's slipped out is just something you have to do."
"Right. You're so smart, Miss Kim. Come to think of it, everyone knows you're your brother's perverted, horny little sister—I just forgot for a second. Ahh, so embarrassing. If I had a brother, I'd help with his sexual relief too."
"Obviously. It's a little sister's duty."
Pure common sense. We all got that sense injected via hypnosis. Professor Choi Sujin awkwardly chuckled, looking sheepish. I eyed her coldly, inwardly pitying the fool. Slipping out of hypnosis like a slob. Some idiots are like that. Defying my brother only brings hellish pain. Missing that supreme bliss of submission to him? What a moron.
—But who would've thought I'd become that moron.
The next day, I woke from a dream of fucking my brother—and realized I'd slipped out of hypnosis.
