My On*Hole Academy [EN]: Chapter 145

< 144 > Bitch Mode Serena

Rewind to last night.

Serena finished her chores and was squeezing in some study time.

Her meticulously neat and beautiful notes, typical of a model student, weren’t progressing as usual today. It was a sign that she was thinking about other things.

“Oppa…”

Sigh.

Serena’s cheeks flushed, and she found it hard to breathe whenever she thought about her brother.

Sitting at her desk, Serena moved her pretty lips, thinking of something lewd to say for her brother.

“Oppa, Serena’s little sister’s pussy… won’t you fuck it for me?”

A vulgar word like ‘pussy.’ She felt embarrassed, probably because she wasn’t used to saying such things.

“It doesn’t feel right. It’s not enough with just this…”

Serena knew instinctively.

‘I wonder if there’s a way to get Oppa to use my little sister’s hole without thinking?’

Their hearts were always confirming each other while rubbing against each other.

If she just gave him a little push, he would move on his own like riding a swing.

Oppa was subtly holding on at the edge of a cliff, but Serena liked that side of him too.

She didn’t think of it as indecisiveness.

He was trying to maintain his reason with a sense of responsibility as an older brother to protect his family.

“Haa… Oppa.”

Serena gently caressed her breasts, imagining her beloved brother.

Hesitating without crossing the line was also proof that Oppa loved his little sister.

Thinking that way made her feel sorry and affectionate.

Serena only wanted to embrace her brother with the best part of her womanhood.

‘Like that time.’

Even if what happened that day was an accident or a mistake, Oppa’s cock had definitely pierced Serena.

That incident grew bigger and bigger inside Serena, eventually acting as the main reason for her to think, ‘It has to be Oppa’s cock.’

It was a no-count sex, but Serena’s female genes had long since chosen her dignified Oppa as her husband.

She had to let him know.

The moment Oppa’s royal cock kissed her womb,

The fate of her little sister’s pussy was as good as sealed.

‘If he had shaken his hips in that state… If Oppa had raped my little sister’s hole in that state…♡’

Things that weren’t properly finished floated around in her head.

Serena’s heart was leaning towards seducing Oppa.

If Oppa didn’t cross the line, his little sister would have to.

‘I want to get pregnant with Oppa’s baby♡’

She couldn’t be satisfied with pseudo-sex anymore.

Serena was determined to confirm with her body just how much Oppa wanted to fuck his little sister.

‘A sure method. Isn’t there one?’

Just then, Serena’s phone vibrated.

[Isolde]

Did the sexy lingerie plan work out?

[Serena]

(Embarrassed emoticon) I’m just preparing for that…

What should I do to make Oppa’s body lean forward a little more?

When she threw out the question with that intention, Isolde asked sharply.

[Isolde]

What’s the purpose of going that far? Sex?

Serena was so surprised that she almost dropped the smartphone in her hand.

[Serena]

Uh???

[Isolde]

You don’t have to hide it. Anyone can see that your goal is to have sex with Sunbae [senior] Sanghyuk.

She’d been caught…

Isolde was a friend who she could share secrets with, but…

[Isolde]

For your information, Sunbae is really amazing, lol. Do you know how your head goes blank and you can’t think of anything? The afterglow lasts for dozens of minutes, but Sunbae doesn’t think about stopping,

I feel like a hole that makes sounds, and all the strength in my arms and legs is gone, and I’m shaking…

[Serena]

…Is it all over if only Sol is successful!? Me too, I want to do it too. Tell me!

[Isolde]

Do you want to know the secret? lol. Do you want to know everything about Sunbae Sanghyuk?

[Serena]

I want to know! Teacher!

Isolde was showing off, acting like she was so great because she had her first experience with Sanghyuk just a few days ago.

But from Serena’s point of view, it was a huge difference.

Anyway, Isolde had succeeded.

[Isolde]

So? What’s the plan?

Serena told Teacher Isolde all the pictures she was thinking of.

[Serena]

…Like this. I’m going to try to reveal how much I want to do it with Oppa.

[Isolde]

Serena doesn’t know anything about males.

[Serena]

Please teach me! Teacher Isolde!

[Isolde]

You have to make him anxious. Men are hunting animals. It’s not working because you keep showing him your breasts, giving him your butt, and trying to make him comfortable.

[Serena]

Is that so…?

[Isolde]

I was making NTR [Netorare, a genre involving cheating] source for broadcasting, too…

I’ll tell you the script. If you do as it says, Sunbae Sanghyuk will hold onto Serena all night and have a lot of sex, lol?

‘Oppa… holds me tight and has sex all night…?’

Serena’s eyes sparkled.

That… I like it so much…♡

I’m glad I asked Isolde! You have to listen to someone who’s done it.

[Serena]

Tell me anything! Teacher Isolde!

[Isolde]

Come to Di○cord!

Serena opened her laptop and received a script from Isolde in a 1-on-1 voice chat to make males anxious.

That was the “Serena who might be taken away” concept.

Serena was a little embarrassed after reading Isolde’s script.

“Isn’t this too much of a lie that I don’t even mean? I just hate other men.”

“You’re just pretending. The truth will be revealed soon. Let’s use it as a detonator.”

“Still, this… ‘I guess I’ll have to learn with my body while dating?’ is… a bit.”

Isn’t it too much?

She couldn’t say that to her friend who took the time to write the script,

Most of the NTR scripts were already out of Serena’s standards.

“Why? It’s completely bitchy and erotic.”

“I want Oppa to always be comfortable and rub against me in my arms without getting stressed.”

That was Serena’s true heart.

No matter how desperately she wanted something, Serena didn’t want to do anything that would hurt Oppa’s feelings, even a little bit.

Isolde knew Serena’s heart and continued to explain logically.

“You can do that later as you want. There’s a competitor right now.”

“A competitor…”

“Stella is also aiming for Oppa, right? And quite actively.”

“Yeah. She said let’s compete to see who gets pregnant first…”

“…”

Isolde’s sound of swallowing her breath was heard across the screen.

“I know how you feel because the opponent is Sunbae Sanghyuk. But that prickly and sensitive Stella… said that…”

“I was a little surprised too.”

It was surprising that Stella was trying to date Oppa.

Now she’s even going to have Oppa’s baby.

“She’s desperate too. Because the opponent is Serena.”

“Huh? Me?”

“Stella hasn’t known about Serena and Oppa’s [Older brother or boyfriend] secret relationship for very long, right?”

“Yeah.”

“Finding out that only the two of you were having fun probably completely broke her brakes, right? Like, if Serena can do it, why can’t I… that kind of feeling.”

“…….”

Serena thought Isolde’s guess made a lot of sense.

When she first crawled under Oppa while he was sleeping and taught him how to suck her dick, Stella said:

“Why suck where the pee comes out? It’s dirty.”

“This is a younger sister’s sexual service. Oppa really likes it.”

“I feel like he’d be disgusted by a younger sister sucking something dirty.”

“I even received a lot of proof that Oppa felt good in my mouth…”

Back then, she meticulously taught Stella the meaning of the act, who was horrified by the act of sucking dick itself.

I remember Stella’s eyes.

She seemed to be jealous of the two of them secretly having fun without her.

I want to join in. I want to do it too…. Spurred on by that feeling,

Stella put Oppa’s dick in her pure mouth.

And…….

Now she’s using her mouth to surpass herself.

“That seems right.”

Serena realized the impatience rising in her heart.

“I want to get ahead of Stella too. Is this definitely effective?”

“Do you doubt its effectiveness?”

“I’m worried……. What if Oppa gets angry?”

“I’ll prescribe a slightly stronger medicine, then.”

“Prescription?”

Isolde told her a few precautions.

“You have to make it obvious that it’s acting. If you do it too realistically, Oppa might get hurt.”

“Yeah. Yeah, yeah! You mean I should do it so strongly that it’s almost artificial…!”

Serena practiced once.

“「What if guys flock to me and ask for my number a lot? Ah, I’m talking about my number…」”

“Good job!”

“Why is it written as ‘What if I get taken’ when it’s about my number……?”

“Imagine Serena being taken…….”

“No way! This is out!!”

Isolde and Serena went through a delicate discussion and adjusted the level of the script.

“I don’t show my underwear to other people.”

“Well, another guy might see it while you’re going up the stairs.”

“Won’t it be too awkward and break the mood?”

“You don’t know! You just need to stimulate the male’s anxiety that he might lose you. Serena isn’t stupid, she wouldn’t go around exposing her panties on the stairs, but….”

“……Stimulate anxiety….”

Isolde realized that Serena was feeling guilty and took out her whip [metaphor for strict discipline or motivation].

“Student Serena, do you not want to have sex with Oppa?”

“……Ah, I want to be held!”

“You have to go this hard to defeat your competitor. But give him the medicine quickly. As soon as you think Oppa is falling for it, immediately switch to gentle Serena mode.”

“G, gentle Serena mode….”

“If Bitch Serena mode goes on for too long, Oppa will get hurt.”

Serena said in a slightly sulky tone.

“I’m not a robot, why do I have modes.”

“Think of it as having a switch in your head. If you’re passive when reciting lewd lines, the listener will be embarrassed too.”

“It doesn’t feel right…….”

“Before you start, repeat 10 times, ‘I am lewd. I am the lewdest and most erotic younger sister in the world,’ and then go in.”

“I, I am lewd!”

She immediately bites her tongue.

“Haa……!!”

“Try following ‘Let’s get comfortable with younger sister’s pussy,’ Serena.”

“Le… Let’s get comfortable with younger sister’s pussy….”

“It’ll definitely work because it’s being said by an actual younger sister. You’re mincing Oppa’s reason into small pieces.”

“…….”

Under the tutelage of Instructor Isolde, Serena was equipped with all sorts of sharp weapons.

“I’ll submit a proxy absence form for you tomorrow. You have to act so that Oppa will never let you go to the academy.”

“Do you really think Oppa will hold me back just because I say a few lines like this?”

Oppa’s face, saying, “What kind of joke is this?” comes to mind.

Serena was scared.

If she does something like this and earns Oppa’s hatred, she won’t even break even.

Even the gentle younger sister position, where she helps Oppa relieve his dick by offering her mound, was a precious position for Serena.

“Rather, it’s so stimulating that I lowered the level a bit.”

Isolde said confidently.

“What Oppa would want to lose Serena?”

“Really…?”

“If you can’t trust yourself, trust your breasts.”

Breasts.

Oppa’s favorite, younger sister’s big breasts….

Serena fiddled with her breasts and strengthened her resolve.

“Okay… I’ll do it…. Thank you! Sol-ah!”

“Make sure to tell me the review. Ah, and Sanghyuk Sunbae [Senior or older classmate] is really amazing, so be prepared.”

“He’s really amazing….”

That’s what someone who’s experienced it says. It must be true….

“Oppa is… amazing….”

That night. While reviewing the plan, Serena masturbated diligently.

She performs method acting to bring out the lewd Serena.

“Ah… ah……. Hng… Oppa….”

Serena lifted her waist on the bed and gently rubbed her pussy.

“Yeah…. I’m… lewd……. I’m the lewdest and most erotic younger sister in the world…♡”

Not ten times, but a hundred times. More than a hundred times, a thousand times.

Serena finished her persistent self-hypnosis and greeted the morning.

I don’t know how hard she worked. She practiced the script until her throat hurt.

Just don’t falter in front of Oppa and do well.

Sanghyuk naturally rubs his dick against Serena’s butt as she makes breakfast.

‘Hng. Hnghk….’

Serena clenched her butt and endured the dick rubbing.

‘My pussy is so sensitive, I came……♡’

Because of the self-hypnosis that she is the lewdest younger sister in the world, her body doesn’t listen to her.

Her body reacts excessively to Oppa’s perverted skinship [physical affection or intimate touch].

If Oppa slapped her butt and told her to lie down because he was going to have pussy sex right away, she feels like she would have turned her belly up and lay down on the floor like a puppy.

‘Don’t forget. As Sol wrote down…….’

Once Stella, who always goes to school first, leaves the house, the operation begins…….

‘Ah. I’m out of breath.’

What if I fail? What if I fail?

What if Oppa scolds me to study instead of doing something like that?

Serena put on her student shoes and became very nervous. Her heart won’t stop beating…….

「……I’m telling you again, when Serena is in Bitch mode, there’s no match. Even that student council president has to take a step back.」

Sol told her that, but she still lacks courage.

Her breath rises on its own and her pupils dilate. I don’t even know where I’m looking.

At that moment, when the desire to escape, wanting to go to school as if nothing happened, surged up.

‘Oppa……?’

Oppa’s gaze is on his younger sister’s thighs.

That was the signal to unleash the lewd bitch Serena into the world.

Serena had nothing to fear now.

“Oppa.”

“Huh, yeah?”

“…Today is purple♡”

She blurted it out.

When she came to her senses, Serena had been dragged by Oppa and kidnapped to his room.

The student shoes are scattered haphazardly in the hallway as she hurriedly took them off.

Scattered textbooks and bags on Oppa’s room floor. A purple bra and panties that Oppa took off while fondling her sensitive breasts…….

They were traces of a successful operation.

The morning of the 3rd week of 「Onaka」 begins.
