Ero Academy

The student council president, who had just left the chairman's office, seemed strangely content.

"You are my first project, Kim Sang-hyuk. I'll turn you into a new person."

"…So, what should I do first? I've missed classes."

I decided to simply obey the student council president and work like a dog. Eventually, it would all come to an end.

"You need to attend classes. I've informed the teacher, so go and join the first-year students."

With the first-year students?

"You must participate in the dungeon exploration class, Kim Sang-hyuk. Especially since you're a D-grade. I won't tolerate faking illness to escape."

'Dungeon exploration…'

It seemed my academy life could continue. Surprisingly, it was more relaxed than I thought.

"I'll call you in the afternoon. Be prepared to show up immediately when I call."

"Yes, Mr. President."

"This is my number."

Oh…

I naturally received the student council president's number. This might prove beneficial, I thought.

"Private contact is forbidden. Don't even send a message until I initiate the conversation."

"…"

My hopes were dashed.

As Isabella strode away with an air of confidence, a whirlwind of thoughts filled my mind.

["Assessing Onahole Aptitude"]

[Isabella]

[Strategy Difficulty – None S (Strikeout)][Onahole Aptitude SS+ Grade]

[Virgin][Underwear – Black T-string, nipple patch (no bra)]

[Onahole Traits (★) – A lascivious, perfectly rounded derriere that is truly overwhelming! An impressive waistline, an Onahole specialized in the cowgirl position]

[She is the Student Council President of Ethol Academy and the Head of the Villain Correction Department. Simultaneously, she is one of the famous S-class heroes in Seoul, known by the hero name "White Devil."

Her exquisite face rivals that of top idol 'Lizna May', and her incredibly sensual figure has garnered her a multitude of fans. There are even rumors of "Student Council President merchandise" circulating in the underground market.]

'Black T-string…'

My gaze can't help but linger on her buttocks.

It must be because regular underwear would be too restrictive while riding a horse or engaging in similar activities…

[Onahole Acquisition Quest]

[Grasp the audacious Student Council President's ample rear and indulge in some lewd lovemaking♡]

[Try "Fellatio Anywhere"! You can watch the student council president's vacuum fellatio show!]

As I assessed my aptitude, system messages flooded in like malicious pop-ups. It seemed that Enn's Onahole viral campaign had begun.

"Wow, so audacious. How arrogant!"

*Pop!*

Our adorable blonde goddess appeared and glared at the student council president's back.

*Zing!!*

"How dare you! Interfering with Sang-hyuk's erotic academy life! Let's grab that haughty backside right away and teach a lesson through perverted sex!"

"…Do you really think I'm some kind of perverted sex-launching machine?"

"You've already crossed the line! Isn't it time to let loose and indulge?"

"Why…? Was there a reason for this situation to be like this?"

"Because they're arrogant!"

Enn confidently puffed out her chest and declared.

"…So, because they're arrogant, you want me to grab their rear, force myself upon them, and teach them a lesson?"

"That's exactly what I'm saying! Lucky Perversion: ON!"

"I won't do it!"

Setting aside the evaluation of the student council president's arrogance, looking down from an exceedingly haughty point of view.

I don't understand why that would lead to rape.

Such a drastic leap!

"Uh… Don't we teach about vaginas…?"

"Would you like to start?"

"…I, I'm an unattainable heroine!"

…How strange to speak so crudely, and yet be shy when the target is oneself.

"En. Listen carefully."

"Yes? Please speak!"

"Ordinary people don't think about punishing a woman with rape just because she's arrogant."

"Hmph, Isabella's ass is incredible… I wish Sang-hyuk would enjoy it…"

'…How amazing must it be…'

"If I were to brandish a Lucky Skeve with that mindset, in a month, no, in a week, all the women around me would become onaholes…"

"That's exactly it~."

…

I tugged at En's cheek.

"Havvb. Ofb."

"What do you mean, 'exactly it'? You porn-addicted goddess. Please come to your senses."

"Abbub. To forgive such a brazen pussy… you're far too lenient…"

"Quit lecturing and go on in. I'm a model student who listens well to the student council president."

"You must be an interested student! Bye!"

"This!"

As I tried to hit the teasing goddess, she swiftly escaped.

Ugh.

The time stop is lifted, and I return to the building where I'm attending class.

The group chat was quite noisy.

[Yuuna]

When are you coming? Sang-hyuk, you can't refuse to go to school! I'll come to your house!

[Henna]

ㅜ

[Yuuna]

We have to go to the dungeon, but there are only two of us left, hurry up!

[Kim Sang-hyuk]

You two go ahead. I'm a bit late because I had to meet the student council president.

[Yuuna]

(Emoji filled with question marks) Student council president? Isabella? Why??

[Henna]

…Did you get scolded again?

Haha.

To Henna, the student council president seems to be a figure who scolds Kim Sang-hyuk.

Well, it's more or less the same as being scolded.

[Kim Sang-hyuk]

I'm caught in a weak spot, so for now, I have to follow the president's orders.

[Yuuna]

What?! Wha… What kind of… Hey, did they take a risqué photo of you?

…Why would she even imagine that?

[Kim Sang-hyuk]

Anyway, I'm on my way right now, but there's some distance, so you two go ahead.

[Henna]

Yes.

[Yuuna]

See you at lunch, then!

Hmm. That's settled.

With Henna and Yuuna gone, all the second-year students must have left.

I wonder if Serena and Stella, the first-year students, are here?

I felt a bit tense as I entered the indoor training ground.

I could hear the female students chatting loudly outside.

As I cracked open the door, all eyes were on me.

'There are so many…'

Are all the first-year students gathered here?

There are far more people than when it's just us. Almost 200 people.

I went straight to the teacher.

"Welcome. I heard you."

'Should I go solo without Henna and Yuuna?'

The teacher glanced around.

I searched for familiar faces among the many younger students.

'Serena. Stella.'

As expected of our younger sisters. They're the first ones to catch my eye.

Serena waved with a welcoming smile, while Stella quickly turned her head away as our eyes met.

"Teacher! Please let senior join our party!"

"We'll take them!"

"Everyone, be quiet."

I nearly felt embarrassed, as if I'd been reduced to the status of a hired mercenary. For some reason, I became a hot commodity despite being a D-class onahole collector.

"Stella is Kim Sang-hyuk's younger sister, right? Go as a duo."

"Yes?"

Stella asked incredulously. If it weren't for the teacher, she might have immediately said, 'No way. I'm not going with that jerk.' That's the kind of expression she had… However, since we were in front of hundreds of people, Stella chose her words carefully.

"…But Serena is here too."

It was a statement along the lines of, 'Why me, instead of Serena?'

"Since you're D-class, A-class Stella should take you."

Laughter erupted all around. Although I had never felt ashamed of being D-class due to my ignorance of the academy's social hierarchy, seeing my juniors laugh made me feel somewhat embarrassed.

"Wow, Stella's brother is so handsome!"

"Look over here!"

"…"

Stella glared at me as if she wanted to devour me. I hadn't anticipated ending up in a situation like this. In the end, I found myself squeezed between my sister's friends, waiting for my turn.

Naturally, Stella didn't come anywhere near me, and Serena was the first to approach.

"Oppa!"

"Serena…"

…Welcoming me with such a radiant smile in front of her friends, despite me being a D-class oppa…

My heart melts.

Embrace!

"What happened? How about your class?"

"Ah, I got scolded by the student council president for a bit…"

"Really? That's too much…"

Empathy multiplied by 100.

Serena was always focused on protecting her brother.

My heart is warmed.

In the meantime, I recalled what I saw in the morning, on top of Serena's school uniform…

White panties adorned with a ribbon were seemingly visible beneath her black polka-dot pattern.

'Is this almost like an irresistible force?'

"Is this the oppa you were talking about, Serena?"

"Wow… he's tall."

"He's really handsome…"

Serena's friends gathered around, forming a protective circle around her and me.

"Hello, senior."

Among them, there was a girl with pink pigtails who seemed particularly close to Serena and had come to greet her separately.

"I'm Serena's friend, Isolde."

"Ah, yes, nice to meet you."

Isolde bowed her head.

…The chest is quite large. The first-year students' development is quite remarkable…

"I-I'm Sarika. Hello, senior."

"Mm, hello."

A healthy and radiant brown-haired ponytail girl approaches me.

She's quite pretty as well…

With three heroines in such a small space, it seems I might get an erection without any resistance.

'My sister's friend. Calm down.'

"Please call me Sarika."

"I'm Kim Sang-hyuk. Sarika."

"Uh! Oppa? Did you hurt your hand? Let me see."

Serena clings to my side, playing with her fingers…

She then spreads hand cream on my hand.

Why do they find this so amusing, exclaiming "Ohh" and gasping in awe?

I can't quite understand girls' sensibilities.

"Your hands are really big, Oppa."

"Can I touch your hand?"

"Uh, sure…"

The girls giggle after lightly touching my hand.

Their faces are adorned with unrelenting smiles.

I'm amazed that my mere existence can bring such joy to these girls.

"Senior! May I ask you a question?"

"You can do it."

"Are you truly a D-class adventurer?"

*Swoosh.*

The girls' spirited questions pierce my heart.

"Why do you even ask that?"

"Right. Where would you find a genuine D-class adventurer?"

"Do you really collect Onaholes?"

"I do."

"Kyaa~~."

After answering their various questions honestly, I notice the waiting line has already diminished considerably.

"I wish I could go with you too… I'm envious of Stella."

"Can't the three of us go together?"

"No, we've already formed a team."

"Who's in it? Is it a man?"

"Kyaa!! 「Who is it, a man?」Please do that again!!"

… … .

Serena's cheeks flush as the people around her tease her.

"…I decided to go with Sarika. I'm not going with a man."

"Hmm."

"Are you relieved?"

*Gently.*

Serena intertwines her soft hand with mine.

I'm quite anxious, fearing someone might notice our unusual relationship.

"I'm relieved."

"It's our turn now. We'll be back. Always be cautious in the dungeon, okay?"

"You too, Serena."

Sarika and Serena depart.

As the numerous female students entered the dungeon when it was their turn, the once bustling training ground gradually grew sparse and quiet.

"…"

My sister's friend, the pink-haired Isolde, gazed intently at me…

"Why, why?"

"Can I take a picture with you?"

She is quite the bold heroine. I never anticipated such a request.

"Suddenly?"

"It'll only take a moment."

"…Fine."

After all, she's my sister's friend. Well…

She took out her phone and prepared it for a photo. Attaching her smartphone to a selfie stick, she extended it and crossed arms with me.

…My sister's friend's breasts touch my arm!

*Rub rub rub.*

"Peace~. Serena's handsome brother, I'll try to seduce you with my chest~."

*Nuzzle nuzzle.*

…

"What kind of picture is this?"

"I crossed arms with my friend's brother while she was away."

"Are you obsessed with the number of views?"

I wonder what Serena will say when she sees this later…

"Thank you for your cooperation in filming."

"…Go on in."

Now, I must face the final boss.

Stella, who had been leaning against the wall, tensed up and prepared herself as I approached.

"…Why? It's so delightfully intense, I could die from pleasure. Let it be my end. Brother?"

I couldn't help but smile at the familiar taste.
