NTR manga titles give you a pretty good idea of the content.
『Boy's Corruption』 is a bit ambiguous, but 『My Brother Clings to Mother』 has such a straightforward title that you can grasp the plot without even peeking at the story.
The little brother who loves his big sister but can't bring himself to approach her. The stepdad who can't overcome his desires and ends up violating his daughter.
A setup that feels familiar, like something you've seen before. It's a common pattern in NTR manga.
'In this world, it'll probably play out in reverse.'
Gender swap. That turns it into 『My Brother Clings to Mother』.
Here, the brother refers to Juyeon-woo, and the mother means the Aunt.
'Now I get why Juyeon-hee didn't show up.'
The Aunt had finished work and come home. The head of the household was back. That meant coming out to the entryway to greet her.
Even if you're super busy grinding ranked matches, the polite thing is to at least show your face before heading in.
But Juyeon-hee didn't do that. She didn't even poke her head out.
It went against basic Hongik Ingan etiquette.
'She didn't act like that when I arrived.'
I'd just met Juyeon-hee for the first time earlier.
Was she acting like some kid who'd forgotten all manners back then?
I clearly remembered the warm smile Juyeon-hee gave me as she welcomed me.
That wasn't the face of someone who didn't know the basics.
Juyeon-hee had deliberately stayed away. She didn't even want to come out and say hello to the Aunt who'd come home from work, so she holed up in her room.
'What a messed-up family.'
No need for a long evaluation.
I left the Aunt's room acting like nothing was wrong. Even as I walked away, I could feel her gaze on my back.
The Aunt was leering at me obscenely. It was more blatant than if she'd groped me with her hands, sending chills down my spine.
'...So in moments like this, it lets me move on my own.'
I had control. That's why I could slip away without getting caught.
'Not yet, though.'
The moment the Aunt crosses the line and decides to devour me, my body will end up in her arms. That fate was unavoidable.
It might be a good idea to apologize to my twin little sister in advance before that day comes.
"Oh."
The instant I stepped out of the Aunt's room, my body reacted. It started moving on its own. I wondered where it was headed, and sure enough, it was the kitchen.
My body got to the kitchen and started doing household chores without being told.
It washed the rice, put it in the cooker, and made side dishes. Miso soup. Rolled omelet.
Rolled omelets are such a hassle that I'd never make them, but my body handled it perfectly on its own.
Pro-level skills. It had reached the realm of a full-fledged housewife.
"Your skills are getting better every day, Juyeon-woo. You could get married off right now."
"Haha..."
The Aunt, now changed into comfortable clothes, picked at one of the finished side dishes and commented.
Since I hadn't made it myself, the praise didn't really move me. I just gave an awkward smile and went with the flow.
I bustled around busily. Before I knew it, the dinner table was set.
The Aunt, who'd been watching TV in the living room, came over to the kitchen table on her own without me calling her and sat down.
But Juyeon-hee showed no sign of coming.
"...Tch."
I was too lazy to go all the way to her room, so I thought about just calling out, but nope. My voice wouldn't come.
Looks like I'd have to fetch her myself.
"Aunt, I'll go call Juyeon-hee."
"Okay."
The Aunt set down her spoon for a moment and waited. I headed straight to Juyeon-hee's room. What could be going on in there? I could picture it.
'I want to knock.'
But no chance. Actions required for the manga storyline were being forced against my will.
"Juyeon-hee, time for dinner."
My body flung open Juyeon-hee's door like it had forgotten basic family etiquette.
Walking into my sister's room like it was nothing. Juyeon-woo was one crazy bastard.
'If you can't avoid it, enjoy it.'
I decided to enjoy the situation. I'd watch Juyeon-hee's masturbation as my body guided me.
The moment I thought that, control returned to me.
The bed's orientation was hilariously ironic. Almost like it was set up for this—legs facing the door.
With her legs spread for masturbation, from the doorway, you'd see her pussy first thing.
'Her bush is impressive.'
I admired it inwardly as I watched Juyeon-hee masturbate.
"Oppa, oppaang, Juyeon-woo oppa...!"
Juyeon-hee was lying on the bed, rubbing her pussy. She didn't even notice me come in and was lost in her self-pleasure. One hand pinching her nipple, the other rubbing her clit, going at it hard.
Then, right on cue, she hit orgasm, her hips trembling wildly.
"Haaang! Ang!"
Squirt! Splurt-!
A milky white fluid sprayed from Juyeon-hee's nipple. My twin little sister's breast milk splashed all the way to my face. It shot straight into my mouth perfectly.
I swallowed Juyeon-hee's breast milk without spitting it out. It tasted different from Geum Tae-yeon's. And then our eyes met.
"O-O-O-Oppa!?"
Juyeon-hee shrieked like she'd seen a ghost and covered herself up. She grabbed the blanket nearby to hide her lower half and averted her gaze.
"W-Why, why'd you come in...!"
"...Dinner's ready. Come eat."
I delivered the message as calmly as possible. It was dialogue I'd chosen myself.
'As long as it's roughly similar, it's fine?'
In these big sister positions, catching a little brother masturbating leads to various reactions.
I went with the mature, level-headed one. The kind older brother who doesn't pry and just moves on.
"..."
Leaving my completely frozen little sister behind, I quietly backed out and closed the door for her. She probably needed time alone to process this.
When I returned alone, the Aunt, looking puzzled, asked,
"Where's Juyeon-hee?"
"She said she'd finish the problem she was working on and then come eat."
"Juyeon-hee? Studying? That's unexpected."
I covered for Juyeon-hee. The Aunt didn't press further.
Dinner began with one person missing.
Juyeon-hee didn't come out until the Aunt had emptied her bowl twice.
I went to fetch Juyeon-hee again. This time, my body moved on its own.
It even knocked.
Knock knock knock-.
"Juyeon-hee, dinner."
No response from inside. It felt like someone was there, but no reaction.
Nothing seemed wrong.
Still, I had to act concerned. Casually strolling in would kill the vibe.
"I'm coming in, Juyeon-hee."
And I opened the door right away.
Juyeon-hee was lying on the bed, curled up under the blanket like a kid with a cold.
"Juyeon-hee."
I called her name and approached. Despite being just a minute or two older, Juyeon-woo had a more mature personality than Juyeon-hee.
"Come eat, quick."
"...N-No... I don't wanna..."
Even when I tugged the blanket, she wouldn't budge. She was holding on tight from inside.
Juyeon-hee had no intention of coming out from under there.
I needed to get her out. My body handed control back to me.
I continued the conversation with Juyeon-hee as I wanted.
"I get it, Juyeon-hee."
First, show empathy. Everyone masturbates; it's human nature.
"I masturbate a lot too, just like you."
I lay my cards on the table. To ease her shame.
Juyeon-hee stayed curled up under the blanket, mumbling.
"...You don't have to comfort me, so don't lie."
"I'm not lying."
It's the truth. Not forced by the body for the storyline, but words straight from my mouth.
'Thanks to Geum Tae-yeon, I don't even feel like masturbating anymore.'
Masturbation requires pent-up lust. With my balls completely drained, I couldn't do it now.
That didn't erase my past sessions, though. Countless sperm that died in tissues, the thick, musky smell they gave off—it was real.
"Masturbation is natural."
I said it with as much shameless confidence as I could muster. Thick skin on my face helped.
"It's not weird at all."
Rubbing your pussy fantasizing about your twin brother is weird.
But I won't say that now.
'Should I jerk off in front of her?'
Dialogue blocked.
Okay, different line.
"So, don't avoid your oppa too much."
Stay the kind older brother to the end. It fit Juyeon-woo's personality.
"..."
Juyeon-hee didn't get up from the bed. Facing me right now was probably too much.
'Let's leave it here and step back.'
I'd see the results tomorrow. I carefully slipped out of Juyeon-hee's room.
I went to the kitchen and cleaned up after dinner.
And so, an ordinary day passed.
Preparing breakfast was my role too. No one told me to, but I did it willingly.
Domestic type.
My body yawned as it made simple toast.
"Juyeon-hee, you up?"
The Aunt, ready for work, was eating breakfast.
Juyeon-hee glanced warily at me and shuffled out hesitantly. I smiled brightly at her and said,
"Eat your breakfast, Juyeon-hee."
"...Yeah..."
We finished breakfast and headed to the academy.
