My On*Hole Academy [EN]: Chapter 144

< 143 > Who’s Hotter, the Blonde or Brunette Little Sister?

I peeled Stella off me and said,

“This big brother doesn’t do that with *any* of his little sisters.”

There’s a time and a place to be petulant. But is it really okay to ask your brother which one he’d rather sleep with?

“Huh? Honestly, Big Bro, who do you think would be better to, you know, *do it* with?”

The tale of “Which Cow Works Harder?” came to mind. It’s a Korean folktale about fairness and perception.

Prime Minister Hwang Hee, traveling incognito, once saw a farmer plowing a field with a yellow cow and a black cow yoked together…

He asked the farmer which of the two cows worked harder, and the farmer, making sure the cows couldn’t hear, whispered in his ear,

“The yellow cow works harder…”

In other words, according to that tale, Stella is better at sex…

No. Damn it. That wasn’t the moral of the story, was it? Where did my brain short-circuit?

“I love you both.”

“Big Bro~! Don’t dodge the question~!”

“I love you too, Oppa~.”

Squeeze.

Serena’s breast pressed against me, and I realized the whole truth.

The farmer already knew the black cow worked harder, but he was trying to boost the yellow cow’s spirits… He was being considerate.

“Big Bro, I’m sorry for saying harsh things yesterday… I was being needlessly proud… but the truth is, I really, really love you…”

That was all part of Zhuge Liang’s [Gongming’s] strategy, and in reality, the farmer was a master of reading the situation.

“Oppa, wanna think about it while touching my chest?”

…What kind of concept is ‘works well’? Even if the yellow cow excels in teamwork, the black cow might be superior in physical strength. Or is it pure skill, perhaps?

Amidst the confusion, I touched her chest anyway.

Squish, squish.

“Serena’s are too big. Isn’t the baby going to get tired and cry while eating?”

Despite Stella’s jab, Serena has the composure of someone who has it all. From the start, she monopolized my attention with her breasts, so she doesn’t get angry at all.

But it was me who reacted to those words.

“Stella.”

“…Why…”

Stella answered a bit curtly.

“Don’t do that. You shouldn’t put others down.”

“…”

To comfort the sulky Stella, I hug her tightly again and give her a kiss.

Stella receives my kiss and says with eyes that have become the kindest in the world.

“Chu… Chu-lup… I’m sorry, Oppa…”

“Apologize to Serena.”

“I’m sorry for saying you have breasts that make babies cry while eating…”

“Huh? I’m okay with it…! Oppa will definitely have many new sisters-in-law and many children, and the more I can feed them, the better…”

Serena said shyly, smiling.

Already thinking about feeding the babies of her future sisters-in-law?

It struck me anew that Serena is an amazing heroine. Not just anyone gets the reputation of being a hexagonal onahole [a perfect sex partner].

“It’s always like this, so I’m the only one who feels inferior…”

“Haha…”

I know what that feels like.

Stella is probably feeling impatient and resentful towards Serena, against whom a fair fight can’t even be established from the start.

“Did you guys make some kind of bet while I was gone?”

“A competition to see who gets pregnant first…”

“…”

“…”

「Oppa. Wake up… Ugh… Really, does a pregnant little sister have to come wake you up from the morning? It’s morning. Baby’s daddy♡」

「Pervert Big Bro, are you happy that your little sister is having a baby~? I’m happy too♡」

…A dizzying fantasy flashed through my mind.

“So… Serena feels the same way…?”

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

“Y-yes…”

…My body is hot. It wasn’t just because Stella was clinging to me.

“What are we going to tell your mom?”

“We’re all adults now… I think we’re old enough to take responsibility…”

“Still, between family…”

Stella kissed my lips softly, whispering.

“The line that families should keep… we’ve already crossed it many times, haven’t we? Big Bro.”

I felt a pang of guilt.

Even today, I’ve been touching Serena’s breasts every time she comes into view, haven’t I?

I just assumed she’d let me, so…

In the suddenly serious atmosphere, Serena said in a high tone.

“A-also. You know? The 300,000 coins Oppa gave me are almost all still there…!”

“…If we’re short, Serena and I can earn more! We’re capable enough!”

“No, it’s not like we necessarily *have* to get pregnant…”

There are countless ways to avoid pregnancy. It’s just that we’re not trying to, so we’ll get 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 from the very beginning, it’s strange that we’re even having this discussion. It doesn’t make sense.

But because we’re fitting realistic puzzles within that strange story, both my little sisters and I are getting *hotter* [뜨거워지고] in real-time.

Clearly, we’re having the same fantasies right now!

“When did you two start competing over who would do it first, and now you’re both appealing to me so nicely?”

Stella lowered her eyes shyly.

“S-Serena and I have always been close, you know?”

“This isn’t something you can decide *lightly* [함부로]. It’s more serious than you guys think.”

I have no choice but to say what I have to say as an adult.

“If you’re uncomfortable with skinship, tell me. I won’t do it anymore.”

“I’m not uncomfortable! Not at all!”

Serena said, waving her hands.

“I want Oppa to keep… relieving me. With my body…”

“Sex is another matter.”

I, who made my girlfriend and her mom pregnant side by side just the day before, am now going to make my little sister pregnant…

Well, from a third party’s perspective, it’s understandable.

But little sister pregnancy sex is a problem in a slightly different category.

“If my girlfriend gets pregnant, we can be *blessed* [축복 받을 수], but if you guys get pregnant, the whole family will be *pointed at* [손가락질 당해]. It’s not a problem you can decide based solely on desire.”

In fact, having a speed-violation baby [a baby born out of wedlock] with a female student from the academy is also something that could be *criticized* [문제 삼을 여지], but…

“I have a duty to protect this family.”

“Even if we’re adopted siblings…?”

Stella asks me *earnestly* [애틋하게], 쪽쪽 [kissing sounds]. I never thought it would be Stella, not Serena, grabbing my pant leg in this situation.

My heart aches too.

Because we’re not blood-related, Serena and Stella will definitely be able to give birth to healthy babies if they receive my seed…

Physically, we’re men and women at our peak. If we decide to *stick together* [붙어 먹기로], sparks will fly just from making eye contact.

“Because we’re adopted siblings. Even more so… If we make even one mistake, there’s no *restraint* [고삐].”

“Yeah…”

「Because we’re not blood-related」

…Using that *perfect excuse* [절호의 핑계], we’ll be having *a lot of* [엄청나게] sex, right?

“Let’s think about it more seriously over time. Okay?”

“Okay. 오라버니 [Oraboni – Older brother in Korean]…”

Stella listens to me well, as always.

I barely managed to shake off my little sisters’ temptations and returned to my room, where En-chan was waiting for me.

“Ugh, En-chan…”

“Why? Do you have something to feel guilty about?”

“Not really… I only said what was right.”

En giggled.

“…While rubbing against Serena’s butt.”

큭…!?

“Someone who knows very well that minor problems aren’t even problems because it’s a ‘ya겜’ [adult game] is also doing a pretty good job of playing the realistic big brother role?”

“Ha, what are you trying to say?”

“Give up the futile resistance and just be happy while having happy-love-perverted-pregnancy-sex with the sexy heroines!”

…I locked the door tightly, worried that my little sisters on the first floor might hear those words.

You’re a perverted terrorist. What is that?

“Just go around impregnating people with mere desires. This is originally that kind of game! Why else would the title be Onahole Academy?”

“I’m already doing that enough!”

“But why are your words and actions suddenly different? You were doing so well with Yuuna’s mom!”

“My little sisters are special…”

Yeah. I know too.

The affection my little sisters have for their brother is not something you can stop even if you try.

“How long will that tiny bit of reason last~?”

I grabbed En-chan’s cheeks and pulled them left and right.

“Habub!?”

“I’ll endure it, even because of you. You little rascal.”

En said, stroking her reddened cheeks.

“Sanghyuk-nim is underestimating Serena too much.”

“Underestimating?”

…What is she talking about?

“You’ll find out soon! Loser♡”

The goddess of ya겜 spoke as if she could see everything clearly and then left.

What is it…?

‘This time, En is right…’

OnaAka is a ya겜. A very vulgar ya겜 at that.

I know that having pregnancy sex with my little sister isn’t a big problem.

Even the harem I built while attending the academy and making two of my friend’s moms pregnant would be a mess if applied to reality.

Still, I was hesitant to cross the final line.

Since a step-sister is also a sister.

Nothing happened in the afternoon.

It was partly because I was cautious, but also because my sisters seemed to be contemplating something due to my refusal, which wasn’t really a refusal.

They didn’t come to visit me at night or anything.

Has there ever been a day like this since the possession?!

The third week of OnaAka [OnaAka is a ya겜 (adult game)] begins with an eerily wholesome morning.

We all get ready for school after filling our stomachs with the warm meal Serena prepared.

“I’ll head out first, Brother.”

“No kiss?”

Stella blushed slightly and came over to kiss me on the cheek.

*Smooch*

I was worried because she kept her distance after hearing what I said yesterday, but it seems like everything is back to normal now.

“I’ll help Serena clean up a bit and leave last.”

Stella leaves, and Serena and I stand at the front door of the house.

I watch Serena put on her school shoes, and En-chan’s words come to mind.

「Sanghyuk-nim is underestimating Serena too much」

Underestimating? Am I missing something?

Today, Serena’s thighs under her school skirt are a bit more noticeable. White, translucent skin… Very tempting thighs with some meat on them…

She’s not wearing her usual exemplary pantyhose?

‘……White knee-high socks…?’

Serena? Why?

As I was thinking that, I made eye contact with Serena, who turned around.

Serena was in a very… high state. Is something incredibly exciting about to happen from now on?

Serena’s eyes were sparkling as if she was finally meeting the moment she had been anticipating and looking forward to.

“Oppa [Korean term for older brother, used by females].”

I flinched, thinking she caught me peeking at her white stockings.

“Oh, uh?”

Serena lifted up one side of her skirt herself.

“…It’s purple today♡”

Huh. Panties are not the problem here!?

Just lifting the skirt exposed a dramatically larger area of bare skin, revealing her ample thighs and mons pubis……!

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

I remembered.

Serena, buying a flashy patterned, skimpy, and precarious thong that a student her age shouldn’t have.

Serena smiled, holding the string part of the underwear with her fingertips like the fuse of a bomb, and putting one finger to her cheek.

“Oppa. Are you watching?”

“Y-yes….”

I’m watching…….

[Illustration]

“What do you think will happen if I let go of this?”

If she lets go…. If she lets go…… it’ll come off, and her pussy will be exposed…?

The underwear string that Serena gently pulled up is precariously weighing the fate of the underwear that covers her pussy.

“……You. You were going to go to the academy like that?”

“Yes! Because I wanted you to feel energized all day today with my underwear information.”

“I’m fine with that, but other guys will see it even a little bit….”

Serena narrowed her eyes and smiled so sweetly, as if she couldn’t help but love me…….

“It’s especially daring today, so they might see 「more than usual」. The skirt is also short, so a man might accidentally see the underwear I bought to show you while going up the stairs…….”

“…….”

Could she be… inciting me…?

“Don’t worry, Oppa? My chest, from head to toe… doesn’t know any other man but you.”

Doo-geun. Doo-geun. Doo-geun [onomatopoeia for a heart beating fast].

I stiffened my dick and gradually approached Serena.

“But if you don’t claim me…… I’ll eventually marry another man, right? If there’s a man who comes on to me starting today… I’m thinking of getting to know him little by little.”

“What? Getting to know him?”

“I’m not at an age where it’s weird to date, am I? At home, I’m your sister, but outside, I’m just a female student who wants to date….”

What kind of trial is this?

En once told me. Can you endure even if the heroine is connected to another man?

Why is the heroine a heroine? Can I accept such a thing as reality……?

“I’ll probably get hit on a lot today, right? Wearing such flashy underwear…… The top might be see-through.”

……See-through.

Looking closely, the underwear is definitely flashy. I can’t help but be conscious of Serena’s breasts.

If the underwear is visible through the gap in her unbuttoned shirt, the vivid purple will pierce right through my eyes.

“What if men flock to me and hit on me a lot? Ah, I’m talking about exchanging numbers…♡”

This girl…….

She had that look in her eyes because she was excited about seducing her brother with a lewd script!

“Among those many men, I honestly don’t have the confidence to distinguish who will genuinely see my heart and date me purely…….”

“Serena.”

“For now, I guess I’ll have to learn with my body while dating, right?”

Serena fastens her underwear string and turns around. I grabbed Serena’s body from behind as she was about to go to school.

“Don’t go.”

“Ah, Oppa…….”

“…Don’t go to school today.”

“Okay. I understand.”

I was surprised that she agreed so readily.

“I won’t go if you tell me not to.”

……Ah. I’ve been caught.

The moment I revealed my true feelings, the mask became meaningless.

What’s with being an adult?

Relieved, I rubbed my dick against Serena’s big butt and fondled her breasts.

This is it…!!

“Eup, ahn.”

“Serena… Serena….”

“Yes, I know. Ah…. It’s your exclusive breasts…. Are you relieved…?”

“Don’t go anywhere today.”

I grabbed Serena, who was even carrying her bag to go to school, and took her to my room.

During student days, when you slightly exceed the time to go to school, the world can be so quiet.

Such a morning air and sunlight pouring in, a morning right before being late….

“I lost. Serena… I want to have pregnancy sex with Serena…!”

The brother who was having 「a story to tell as an adult」 was clinging to Serena’s ample and seductive body.

“Oppa, kyaaa…….”

Serena smiled with half embarrassment and half joy, entrusting her body to me.

“Actually, I want to! I want to fuck Serena so badly! Serena…! I want to cum in Serena’s pussy!”

“Okay. Okay, so…. Hyaang [sound of moaning]…. Oppa…. I’ll let you impregnate your sister’s pussy, so calm down……♡”

*Chwaarruk [sound of something tearing].*

Serena’s bag was scattered on the floor along with her textbooks.

The purple thong and bra that I forcibly took off by reaching in are scattered haphazardly on top of them.

I dragged Serena, who was wearing only her school uniform with no panties and no bra, onto the bed.

Serena doesn’t resist at all as her brother does whatever he wants…….

Rather, she prettily kneels down and raises her butt as if she’s helping.

*Hwaaak [sound of something being exposed]…….*

The huge butt that the short skirt couldn’t cover came into view.

I pulled down my pants and took out my erect dick.

In the meantime, Serena gently shook her butt left and right♡♡

She moved as if to induce my raging dick.

“I’m sorry for making you feel uncomfortable. Oppa♡ Let’s get comfortable with your sister’s pussy, okay?”

“……Serena, who used to get spanked by me and scolded…!”

How dare, how dare you design your brother?

“Do you want to be scolded with my raw dick?”

*Chyaak chyaak♡ Chyaak chyaak♡ [sound of slapping].*

When I slapped Serena’s moist sister’s pussy with my glans, Serena didn’t know what to do and stuck out her butt.

“Like that time…. Will you *jjoohk [sound of something wet entering]* in your sister’s womb with your hard and dignified dick?”

*Kkwaak [sound of grabbing tightly].*

I grabbed Serena’s butt so she couldn’t move.

“That was a mistake. But…….”

Grab Serena’s butt?

What am I trying to do…? Was I trying to bury my erect dick in my sister’s pussy and fuck her like a dog?

At that moment, when I let go of my hand and was flustered. Serena shook her butt gently from side to side.

“Oppa! The bad feelings that soared earlier…… It’s not good to have them! Quickly put it in here with your dick♡ I’ll melt it carefully with my sister’s pussy♡”

“Serena……?”

“It’s here. Oppa. Don’t think, just stroke your dick with your sister’s pussy and feel good, okay?”

Serena spread one side of her butt with her hand, showing me her pussy hole.

Ah.

Immediately, I put my weight on Serena’s pussy hole and inserted my erect dick.

*Jjyuboop♡♡ [sound of something wet sliding in].*

*Kkoohk kkoohk……♡ [sound of thrusting].*

Covering Serena’s top with my whole body, I inserted my dick all the way in at once.

*Jjyugeok♡ [sound of something penetrating deeply].*

“Eungeuk!!”

*Kkoohk…. Kkoohk….* [sound of thrusting].

Once I insert it and stay still, Serena’s pussy adjusts to my dick in real time.

My lovely and kind sister’s pussy that I’ve been with since the first day of possession♡

Finally……♡

What was all that pretending to be nice yesterday…?!

En-chan might have already known that there was no substance in my words.

In the end, this is it…….

I absolutely hate giving Serena to another man!

“It’s not a mistake this time, Oppa……♡♡”
