Ha Yuna's Regret, Dark Obsession, and Misunderstanding
I am a terminal-grade, ultra-cute pretty boy.
I have a small build and a face that screams pure kawaii.
But one part of my body is definitely not cute.
In fact, it is downright vicious.
My cock was a rare, massive specimen in my previous world, and the same held true in this gender-reversed world.
Normally it was a decent enough size, but once it started getting hard, clothes could no longer contain it.
My patience had finally hit rock bottom.
Seeing Sieun noona in that pathetic, dripping state, my cock ended up rock-hard.
My massive member stretched the waistbands of my pants and underwear to their absolute limit.
Sieun noona lost the ability to speak at the sight of my vicious cock, so mismatched with my adorable appearance.
She lay on the floor like a frog on its back, legs spread wide, silently staring at my enormous dick.
“Hic…”
The thought of my cock plunging into her seemed to excite and terrify her at the same time.
Sieun noona couldn’t tear her eyes away from my cock. Her mouth simply opened and closed, over and over.
What the… Looking at her right now, it feels like Sieun noona has already completely surrendered to me.
She seems to have accepted total female defeat, mentally, without me even needing to fuck her.
Hmm… Still, I should probably use Sieun noona’s pussy after all.
Experiencing it with her body will make it real.
Besides, I’m insanely horny too.
With my cock this hard, it would be torture not to use a woman as beautiful as Sieun noona.
I stripped off my pants and underwear completely.
I slid the panties Sieun noona was wearing to the side, exposing her pussy.
It was a beautiful, hairless mound, meticulously maintained.
Her pussy was a tight, closed slit, and the inside was a lovely shade of pink that practically shouted, “I’m brand new!”
I had been calling it a leftover pussy this whole time, but Sieun noona’s cunt possessed the highest level of erotic appeal.
“Heh heh. You pathetic bitch. Be grateful~ I’m going to specially grace your inferior leftover pussy~ Every time I fuck that hole, the price is ten million won. Later, get on your knees naked and pay up properly~”
“Ugh…! D-Doyun…! You’re really going to…!”
“Don’t call me Doyun~ I don’t want a pathetic masochist like you using my name~ If you’re going to call me something, call me Master~”
“Ah…! Y-yes…! M-Master…!!!”
“Also. When I’m kind enough to use a worthless masochist cunt like you, that tone is way too arrogant, don’t you think? So just stay quiet~ Have you ever seen an onahole talk?”
“…!”
Okay. With that, I’ve successfully imprinted the title of Master and shut her mouth.
All that remains is to shove my cock into Sieun noona’s pussy.
If I completely defeat her pathetic cunt with my massive dick, I’ll be able to make Sieun noona submit entirely.
After that, she won’t be able to defy me anymore.
Hmm… Shall we begin?
“Haaahk…!!! Haaahk…!! Haaahk…!!! M-Master…!!!!!”
“Huuu…!!! Uuu…!!! I’m still…!!! Still cumming…!!!! If you thrust in now…!!!! My pussy will break…!!!!”
“Heek…!! Heeek…!!! Haaahk…!!! It feels so good…!! It feels way too good…!! More, please…!!! Fuck me harder…!!!”
“Haeh… My pussy… belongs to Master now… If Master says the word… I’ll run over and spread it open anytime…”
“Huuuu…!!! Huuung…!!!!! Please don’t press on my womb…!!!! It has to hold Master’s precious cum…!!!!”
“Haeh… Uuu… I’m so happy… Being used by Master feels so good… Master… you’re the best…”
“Uung… Hueh…”
“…”
“…Wow. I got a little too excited without realizing it. I didn’t originally plan to go this far…”
I don’t know how long we had sex.
What I do know is that it was nowhere near normal, moderate sex.
Since this was my first time in this life, I must have been quite excited.
In the end, I fucked Sieun noona so violently that she passed out from exhaustion.
Even a cat in heat wouldn’t mate this fiercely…
Sieun noona was already a pervert to begin with, but now I feel like I’ve become one too, and it leaves a bad taste in my mouth.
…Well. Good is good, right?
With this, I’ve successfully conquered both Sieun noona’s body and mind.
From now on, there’s zero chance she’ll ever threaten me physically.
Not to mention she won’t bother me anymore either.
Because I trained her so thoroughly, the impression I left on Sieun noona is less “husband” or “boyfriend” and more “Master.”
If I had to classify it, Sieun noona is now my onahole.
Tools and people can’t get married, so she won’t beg me to marry her anymore.
Hmm… She’ll probably throw tantrums occasionally in heat, demanding I use her pussy, but that much is fine.
It’s a hundred times better than her forcing me to marry her with physical threats.
“Ugh… I came so many times in one go that my body feels exhausted… I need to sleep.”
If I leave Sieun noona like this, she’ll clean up on her own.
I turned my back on her cum-soaked body and returned to my room.
Oh, and there’s no need to worry about contraception.
Hunters can directly control whether their eggs get fertilized.
If she does get pregnant, I’ll tell Mom and Chaewon noona everything that happened today and swear never to have sex with her again, so that should be enough to stop it.
“Uwaah… I’m so tired… I just want to sleep…”
Maybe because I released so much semen, my body felt heavy.
It was already late, too.
I was so tired I could pass out just like Sieun noona.
The moment I reached my room, I collapsed into sleep.
Woonnya-nya…
In the end, I had sex with Sieun noona, but…
Well… it’ll work out somehow.
For now…
Let’s just sleep…
Zzz…
Gurgle…
Ah… The moment I opened my eyes, a monster roared inside my stomach.
I was so hungry I felt like I could eat anything.
“Ugh… Come to think of it, I didn’t eat properly last night either… And after that intense mating session with Sieun noona, of course I’m starving…”
Ugh! I have no strength from hunger, but today is still the start of a powerful and meaningful day!
I forced myself out of bed with a grunt.
When I checked myself in the mirror, I was still wearing yesterday’s cosplay outfit.
Ah… I fell asleep without changing into pajamas.
I must have been really exhausted yesterday.
Hmm… I’m too hungry to bother changing clothes right now.
I’ll just eat like this and change when I shower.
I headed downstairs still dressed in the cosplay.
On the way to the kitchen, I ran into Ha Yuna. She looked extremely flustered.
She was so startled that her usual sharp, venomous eyes had gone perfectly round.
“Wait… You… What are you wearing…?”
“This? It’s nothing. Don’t worry about it.”
I had neither the energy nor the reason to explain to Yuna why I was wearing the cosplay.
I ignored her and kept walking toward the kitchen.
That was when I felt a strong grip on my wrist.
When I turned around, Yuna was holding onto me.
For some reason, her expression was far from normal.
She looked angry… but also afraid.
…Why?
Why is Ha Yuna acting like this?
“Tell me the truth. Why are you wearing those clothes? Did someone ask you to wear it? Or are you trying to get people’s attention? You’re not… taking pictures in that and uploading them online, are you?”
Ha Yuna wasn’t understanding the cosplay at all.
Instead, she had misunderstood and assumed I was wearing it to get attention from women.
Yeah. I can see what she’s worried about.
If I saw a family member walking around the house in cosplay, I’d probably worry too.
But that’s not what this is at all.
I don’t need people’s attention, and I’m not starved for affection.
So she doesn’t need to worry.
Sheesh… She’s being so serious that it’s hard to even joke around.
I should just tell her the truth.
…No. Telling the full truth might be awkward…
After all, I only wore it because Sieun noona asked me to.
If I say I did it for Sieun noona, it might put her in a difficult position…
“…Hey. Why aren’t you answering?”
When I stayed silent while thinking, Yuna’s expression grew even more serious.
She pushed me against the wall.
She kept interrogating me, demanding an answer.
Normally I would have responded to her rude behavior with something playful.
I would have thrown out some harsh words and brushed it off like usual.
But the look on Yuna’s face as she stared down at me was so sad…
…I just couldn’t do it.

“Why… are you wearing such embarrassing clothes…? Why… are you willing to degrade yourself just to get other people’s attention…? Don’t do that… Please value yourself more… You’re not… a guy who should be treated like that…”
“Ah… Yuna. You’re misunderstanding. I didn’t cosplay to get women’s attention. There’s a very clear reason for it.”
“Then tell me. Why are you wearing those clothes?”
“Ah… That’s…”
“See? You can’t say it. You wore it for a reason you can’t tell me, right?”
“Haha… That’s not it…”
“…Is it because of me? Did I say cruel things to you… and make you thirsty for love? If that’s the case, I’ll apologize. I’m sorry for speaking so harshly to you all this time. I never once… hated you. No. I never hated you, oppa. Actually, I’ve always truly cared about you.”
“Ah… Haha… Yuna. Just listen to me—”
“Unlike our sisters, you’re fragile, right? So I didn’t know how to treat you. I didn’t know how to approach you or what kind of face to make when looking at you. To me, you were completely unfamiliar and difficult. So… without realizing it, I took the easy way out. You’re obviously different from our sisters… but I ended up treating you like a girl. I’m really sorry. It’s all my fault.”
“…”
No matter what I tried to say, it was useless.
For some reason, Yuna kept misunderstanding everything on her own, jumping to conclusions, and eventually apologizing to me.
Her expression was even worse.
She looked like she was about to burst into tears at any moment.
This was the first time I had ever seen Ha Yuna look so weak.
That made it even more awkward.
I had no idea how to resolve this situation.
Just then, someone came down the hallway toward us.
It was my second-oldest sister, Sieun noona.
Sieun noona smiled brightly as if to smooth things over and said,
“Haha. Yuna, it looks like there’s been a misunderstanding. Doyun wore the cosplay because of my stream. I had a mission, so that’s why he did it. There’s no need to worry.”
Sieun noona clearly explained the reason behind my cosplay.
Only then did Yuna realize she had completely misunderstood.
She released my wrist and slowly began backing away.
Her head was lowered so I couldn’t see her exact expression, but her ears had turned bright red. She must have been incredibly embarrassed.
“Ah… Sorry…”
With those last words, Yuna ran to her room.
A moment later, the loud sound of her door slamming echoed through the house.
