Chapter 143 – Who’s More Alluring, the Blonde Sister or the Black-Haired Sister?

I spoke while gently detaching the clinging Stella.

“This brother won’t do anything with any of his younger sisters.”
“Don’t say that.”

You have to ask what you want to know. Is it right to inquire which sister your brother would prefer to have sex with?

“Um? Honestly, I think it would be better with one of them. What do you think, brother?”

“Which cow does the job better?” A folk tale came to mind.
Hwang Hee Jeongseung, who secretly witnessed the scene of a farmer plowing the field with a yellow cow and a black cow…
When he asked the farmer which of the two cows performed better, the farmer came closer and whispered so the cows couldn’t hear.

“The yellow cow does a better job…”

In other words, according to the folktale, Stella is better at sex…
No. Wait. That wasn’t the moral of the story! Where did my brain go awry?

“I love both of you.”
“Brother~~! Don’t dodge the question~!”
“I love you too, brother~.”

With a firm press.

I grasped the entire truth when I was struck by the fullness of Serena’s breasts. The farmer had known all along that the black cow was more efficient, but he had tried to preserve the energy of the yellow cow…

“Brother, I’m sorry for being harsh yesterday… I shouldn’t have let my pride get the better of me… The truth is, I really, really love you…”

This, however, was a cunning ruse, and in reality, the farmer was a master of fact-checking.

“Brother, would you like to think about it while touching my breasts?”

…What exactly does it mean to be good at one’s job? The yellow cow excels in teamwork but is physically outmatched. In terms of pure skill, couldn’t the black cow have the upper hand? Amidst the confusion, I reached out and touched her breasts once more. Fondling them gently.

“Serena, they’re so big. Won’t the baby get tired and cry while trying to feed?”

Despite Stella’s jab, Serena remained composed, like someone who’s confident in what they have. Thanks to her breasts monopolizing my attention from the beginning, she didn’t get upset at all. However, it was I who reacted to the comment.

“Stella.”
“…Why…”

Stella replied, somewhat curtly.

“Don’t be like that. You shouldn’t belittle others.”

“…”

To console the disheartened Stella, I hug her tightly once more and give her a tender kiss. Stella receives my kiss, and with a softened expression in her eyes, she speaks.

“Chu… Churup… I’m sorry, brother…”
“Apologize to Serena.”
“I’m sorry for being the owner of a breast that makes babies cry while feeding…”
“Uh? I’m alright…! You’ll surely have many sisters-in-law and lots of children, and it would be even better if I can nourish all of them…”

Serena shyly smiles.
Is she already considering the feeding of her future sisters-in-law’s babies?
Once again, I realize that Serena is an extraordinary heroine. Not everyone earns the appraisal of a hexagonal onahole.

“Because it’s always like this, I’m the only one who feels inferior…”
“Haha…”

I understand the sentiment.
Facing Serena, with whom Stella doesn’t have a fair chance of competing, she must feel a mix of impatience and sadness.

“Did you two make a bet while I was away?”
“Who gets pregnant first, the showdown…”
“…”
“…”

“Oppa, wake up… Ugh… Really, does your full sister have to come and wake you up in the morning? It’s morning, baby daddy♡.”
“Perverted big brother, are you happy that your sister is having a baby? I’m happy too♡.”

…A dizzying fantasy flitted through my mind.

“So… Serena has the same thoughts…?”

Serena couldn’t meet my gaze and lowered her head.

“Uh, yeah…”

…My body feels hot. It’s not just because Stella is clinging to me.

“What should we say to our mother?”
“We’re both grown-ups now… We’re at an age where we can take responsibility… That’s what I think.”
“Still, we’re family…”

Stella whispered while gently kissing my lips.

“The line that families should respect… We’ve already crossed it, big brother.”

I feel stung.
Just today, hadn’t I touched Serena’s breasts every time she appeared before me?
I did it because I thought, of course, she’d let me touch them…
In the suddenly serious atmosphere, Serena spoke in a high-pitched tone.

“That’s right, isn’t it? Almost all of the 300,000 coins my brother gave me are still there…!”
“…If that’s not enough, Serena and I can earn more! We’re more than capable of doing that!”
“No, I mean, do we really have to get pregnant…?”

There are countless ways to avoid pregnancy. It’s just that we don’t want to take those measures, so we end up pregnant… Is it an act for simple sexual satisfaction, or an act to bear the fruit of love…? The nature of the act changes depending on its purpose.

But it’s strange that we’re even having this discussion in the first place. It doesn’t make sense. However, we’re trying to piece together a realistic puzzle within this bizarre story. Both my sister and I are becoming increasingly aroused in real-time.

Undoubtedly, we’re imagining the same thing right now!

“When did it become a competition over who goes first, and now you two are appealing to each other so amicably?”

Stella shyly lowered her gaze.

“Serena and I have always been close, you know?”
“This isn’t a matter to be decided recklessly. It’s more serious than you both realize.”

As the adult, I have no choice but to address this topic responsibly.

“Tell me if being intimate is unbearable. I won’t do it anymore.”
“It’s not unbearable! Not at all!”

Serena reassured, waving her hand.

“I wish you would continue… to satisfy me. With my body…”
“Sex is a separate issue.”

Just the day before, I had impregnated my girlfriend and her mother together, and now, I was about to do the same to my younger sister…

From an outsider’s perspective, it might seem justifiable.
However, impregnating one’s sister is a matter that falls into a different category.

“Though my girlfriend and her family can receive blessings when she’s pregnant, the whole family will be condemned if you get pregnant. It’s not a problem we can simply decide based on desire.”

In truth, having a child with a female academy student at an accelerated pace would also be contentious…

“Because I have a duty to protect this family.”
“Even if we’re siblings…?”

Stella asked with affection as she leaned against me. In this situation, I never expected it to be Stella, not Serena, who would cling to the waistband of my pants.
My heart aches, too.

Since Serena and Stella share no blood relation, they would surely be able to bear healthy children if they were to receive my seed…
Physically, we are men and women in the prime of our lives. If we were to decide to become intimate, a mere glance at one another would ignite a passionate fire.

“Because they’re step-siblings. Even more so… If one were to make a single mistake, there wouldn’t be any reins to hold back.”
“Mmm…”

“Because they’re not connected by blood.”
…Could it be that this perfect excuse will lead to an incredibly passionate encounter?

“Let’s give it some more time and think about it seriously. Understood?”
“Understood, big brother…”

Stella obeys me quite well.
After barely resisting the temptations of my younger sisters and returning to my room, Enn-chan was waiting for me.

“Ugh, Enn-chan…”
“Why? Do you feel guilty about something?”
“Not really… After all, I only spoke the truth.”

Enn laughed softly.

“…While rubbing against Serena’s behind.”

What…!?

“Someone who knows that trivial problems aren’t even issues due to this being a ‘Yagame’ seems to be quite good at playing the role of a realistic older brother, don’t you think?”
“Ha, what are you trying to say?”

“Abandon your futile resistance, and find happiness in the passionate, transformative love-making and impregnation with the explosively sexy heroines!”

I locked the door tightly, worried that my younger sisters on the first floor might overhear such conversation.
What a perverse terrorist! What’s going on?

“It means recklessly impregnating them, driven by simple desires. After all, that’s the nature of this game! Why else would it be called Onahole Academy?”
“I’ve already done more than enough!”
“But why do your words and actions suddenly change? You got along so well with Yuuna’s mom!”
“Younger sisters are special, after all…”

That’s right. I understand.
The love younger sisters have for their older brother cannot be stopped just by trying to resist it.

“How long will that tiny shred of reason last?”

I pinched En-chan’s cheeks, pulling them left and right.

“Ouch!?”
“I’ll endure it, even if it’s just for you. You little troublemaker.”

En stroked her reddened cheeks as she spoke.

“Sang-hyuk, you’re underestimating Serena far too much.”
“Am I underestimating her?”

…What is she talking about?

“You’ll find out soon enough! It’s going to be a mess♡”

The goddess of nighttime games spoke as if she could see everything clearly and then departed.
What was that…?

‘Enn is right this time, at least…’

OnaAka is a lascivious game. An exceedingly crude one at that.
I know that having sex while trying to impregnate a younger sister doesn’t pose a significant problem.
If one were to apply to reality the fact that I’ve impregnated two of my friends’ mothers and established a harem while attending the academy, it would be an utter disaster.

Yet, truth be told, I hesitated to cross the ultimate boundary.
After all, a stepsister is still a sister.

Nothing eventful occurred in the afternoon.
I did try to restrain myself, but I couldn’t help but wonder if my sisters had any thoughts because of my non-rejection rejection.
There were no nighttime visits to my room.

Has there ever been a day like this since I was possessed?
In a bizarrely wholesome state, the morning of the third week of OnaAka begins.
We fill our stomachs with the warm rice prepared by Serena, and all three of us get ready for school.

“I’ll go ahead. Big brother.”
“Aren’t you going to give me a kiss?”

Stella approached with a slight blush on her cheeks and pressed her lips to mine.

Sigh ♡
Yesterday, I felt anxious because she kept her distance after hearing my words, but now it seems everything has returned to normal.

“I’ll help Serena tidy up, and then I’ll leave.”

After Stella departs, Serena and I stand at the entrance of the house.
When I see Serena putting on her school shoes, I recall Enn’s words.

“**Sang-hyuk**, you’re underestimating Serena too much.”

Am I underestimating her? What am I missing?
Today, Serena’s thighs beneath her school uniform skirt are slightly more noticeable. White, translucent skin… incredibly enticing thighs…
These aren’t her usual exemplary pantyhose?

‘…White knee-high socks…?’

Serena? But why?
As I ponder this, my eyes meet Serena’s, who has turned to look back at me.
Serena seems to be in an exceptionally… exhilarated state. Is something incredibly thrilling about to unfold?
Her eyes sparkle, as if she is finally welcoming the long-awaited and anticipated moment.

“Big brother.”

I flinch, thinking I’ve been caught sneaking glances at her white stockings.

“Oh, really?”

Serena lifted one side of her skirt herself.

“…Today it’s purple♡”

Goodness. The panties aren’t the issue, are they?
Simply by flipping up the skirt, the exposed area of her bare skin increased dramatically, revealing her ample thighs and pubic mound…!

“Don’t you remember? You told me to wear these.”

She recalled.
Serena had bought a pair of tiny, risqué thong panties with an extravagant pattern that no student her age should possess.
Holding the strap of the underwear delicately between her fingertips like the fuse of a bomb, she smiled and touched one finger to her cheek.

“Big brother. Are you watching?”
“Uh, uh…”

Watching, indeed…
“What do you think will happen if I let go of this?”

If she lets go… If she lets go… The panties would come off, revealing her vagina, right…?

The delicate straps of Serena’s underwear, which she had gently tugged upwards, now precariously balanced the fate of the garment concealing her womanhood.

“…You. Were you planning to go to the academy like that?”
“Yes! I wanted to cheer you up with a glimpse of my underwear today.”
“But aside from me, won’t the other guys catch a glimpse too…?”

Serena squinted her eyes and let a captivating smile spread across her face, as if she couldn’t help being so enchanting…

“Today, I’m feeling especially daring, so they might see ‘even more than usual.’ My skirt is quite short, and I bought this underwear intending to show it off to you while climbing the stairs, but another guy might accidentally catch sight of it too…”
“…”

Could she be… encouraging me?

“Relax, sweet brother? My breasts, from head to toe… I don’t know any other man besides you.”

Thump. Thump. Thump.
I approached Serena with my cock standing at attention.

“But if you don’t claim me… one day, I might marry another man, right? Starting from today, if there’s a man who pursues me… I’ll consider getting to know him little by little.”

“What? You’re catching on?”
“Well, I’m not too young or too old to be in a relationship. At home, I’m your younger sister, but outside, I’m just a girl who wants to date….”

What kind of trial is this?
Enn once told me. Can a heroine endure being connected with another man?
Why is a heroine even a heroine? Can we accept such a thing as reality?

“Are you going to attract a lot of attention today, right? Wearing such flashy underwear… the top might even be see-through.”

…It appears see-through.
If you look closely, the underwear definitely stands out. Even if I don’t like it, I become conscious of Serena’s breasts.
If her underwear were visible through the gap of the open buttons, the vivid purple would pierce right through to your eyes.

“What if a bunch of guys come and try to hit on me? Oh, I’m talking about phone numbers…♡”

This girl…
She must have been excited at the thought of teasing her brother with such a lewd script!

“Among so many men, the one person who truly sees my heart and wants to date me purely… Honestly, I’m not sure if I can tell the difference…”
“Serena.”

“First and foremost, there’s no choice but to learn through our bodies while dating, right?”

Serena fastens her underwear strap and turns her back to me. I grab her body from behind as she’s about to head to school.

“Don’t go.”
“Ah, oppa…”
“…Don’t go to school today.”
“Okay, I understand.”

I’m taken aback by her surprisingly obedient response.

“If oppa says not to go, I won’t go.”

…Ah, I’ve caught her.
The moment I reveal my true intentions, the mask loses its meaning.

Who’s the adult here?
Feeling reassured, I rub my dick against Serena’s ample ass while eagerly massaging her breasts.
This is it…!!

“Ah, mmm.”
“Serena… Serena…”
“Yes, I know. Ah… These breasts are for oppa’s use only… So don’t worry, okay?”
“Today, don’t go anywhere.”

I grab Serena, who’s already carrying her bag for school, and take her to my room.
During student days, the world is unbelievably quiet when you slightly exceed your school hours.
On a morning like this, just before being late, with the fresh morning air and sunlight pouring in…

“I give in. Serena… I want to have pregnancy sex with you…!”

As the older brother spoke of “matters only adults should discuss,” he found himself entwined with and rubbing against Serena’s lush and provocative body.

“Brother, ah…”

Serena smiled, half embarrassed and half delighted, as she surrendered herself to me.

“In truth, I desire you! I yearn to make love to you, Serena! Serena…! I want to release myself inside your womanhood!”
“Alright, I understand. Haa… Brother… I’ll allow you to impregnate your younger sister’s most intimate part. Please, calm down… ♡”

With a soft rustling sound, Serena’s bag fell to the floor, spilling textbooks everywhere.

The purple lace panties and bra I had forcibly removed with my hand lay scattered haphazardly atop the mess.

With no panties and no bra beneath her uniform, I pulled Serena onto the bed.
Even as her brother manhandled her, Serena did not resist at all…

Rather, she gracefully lay down, lifting her hips as if to assist.

My breath caught…
Her short skirt could not hide the incredibly ample buttocks now before my very eyes.

I lowered my pants, revealing my erect manhood.
Throughout this, Serena continued to gently sway her hips from side to side♡

She moved as if to provoke his angry arousal.

“I’m sorry I made you feel uncomfortable. Let’s ease your feelings with my little sister’s pussy, okay?”
“…The nerve of Serena, who’s been scolded by me before…!”

How dare she, how dare she scheme like this with her older brother?

“Do you want to be punished with my hard, bare cock?”

*Slap* *Slap*
As he struck Serena’s wet, young sister’s pussy with the head of his cock, she pushed her ass out, not knowing what to do.

“Just like that time… will you thrust your hard, firm cock into your little sister’s womb?”

He tightly gripped Serena’s buttocks.

“That was a mistake. But…”

Grasping Serena’s ass?
What was he trying to do? Was he planning to shove his erect cock into his sister’s pussy and take her like a dog?
As he hesitated, removing his hand, Serena gently swayed her hips from side to side.

“Brother! The negative emotions that surged earlier… it’s not good to hold onto them! Hurry and put your cock in here with me♡ I’ll melt them away carefully with my little sister’s pussy♡”
“Serena…?”

“Here it is, big brother. Don’t overthink it, just slide your cock into your little sister’s pussy and let’s enjoy ourselves, okay?”

Serena, using one hand to part her buttocks, revealed her moist entrance to me.

Ah.

I immediately pressed my erect dick into Serena’s inviting hole, bearing my weight upon it.
*Swoosh* ♡♡

*Tight grip*… ♡
Covering Serena’s body with my own, I pushed my throbbing member all the way inside her in one smooth motion.

*Squelch* ♡

“Ah~!”

*Tightening*… *Tightening*…
Once inside and holding still, I could feel Serena’s pussy adjusting to my cock in real time.

Ever since that first day, my sweet and lovely little sister’s pussy♡

At last… ♡

What was all that sweet talk yesterday about, huh…?
Enn might have already known that my words held no true meaning.

In the end, it comes down to this…

I can’t stand the thought of giving Serena away to someone else!

“You’re right on the mark this time, big brother…♡♡”
