Ero Academy

"I'll take off your shoes for you."

She's going to take off my shoes? Serena squats down and removes my shoes. Afterward, she springs up adorably, grabs my coat, and leads me to the dinner table.

'The aroma of freshly cooked rice.'

Tonight's menu consists of braised ribs. Did she prepare this as soon as she returned from the academy? My sister is truly remarkable. I'm at a loss for words when I see the twelve-dish banquet spread on the table, its legs appearing as though they might buckle under the weight.

"Are you hungry? Brother, go wash your hands."

"What happened today?"

Could it be someone's birthday? Regardless, I head to the shower room to wash my hands and, on my way out, lock eyes with Stella.

"Stella, brother, is back."

"…Yes."

Stella responds quietly and hurries off. Is she feeling shy? Nevertheless, when it's time to eat, we all gather around the table.

"Thank you for the meal."

My two sisters wait for me to take the first bite before they begin eating. The delicate clinking of utensils against dishes creates a cheerful atmosphere.

Serena looked particularly enchanting as she ate.

"What's the occasion today?"

Serena spoke after swallowing all the food in her mouth.

"Well, it's not really a special day."

"I got some money from my brother and gave it to Serena. She handles our finances."

"Oh, that?"

Indeed.

Serena had always been kind to me, but today it seemed she had gone the extra mile.

She seemed to be gauging her brother's reaction.

Stella had already displayed an exuberant reaction—affectionately touching her hand—but,

What about Serena?

"I earned it in the dungeon. Use it for our household expenses."

Serena caught her breath.

"…Indeed. Brother, you're now the very lifeblood of our family's finances."

Nodding.

Stella continued to nod her head as she savored her ribs.

Is it truly that significant? It seems to be.

Rather, since coming here, I seem to have lost my sense of money. It's not won, not yen, but coins.

Isn't it a similar nuance to something that might be tossed around at a bar event?

However, the value of 300,000 coins is, in simple terms, akin to $300,000.

The value might change depending on the exchange rate, but it is approximately 300 million won. Considering one can even trade with devil merchants in this world, the worth of coins is incalculable.

"So… I did my best to make this! You worked hard, big brother."

"Hehe…"

An involuntary smile of contentment appeared.

"Compared to the money you earned, it's not much, but... enjoy your meal."

Serena shyly twisted her waist. Aren't they truly delightful sisters? It's a blessing that they treat their older brother as if he's on a pedestal.

"Thank you."

The meat was seasoned perfectly and tender enough to chew with just the gums. The freshly cooked rice complemented it well. It felt like one could eat without limit.

"One more bowl, please."

"Of course! Just sit down, big brother!"

Serena hurriedly fetched more rice.

"…"

Stella, following suit, swiftly rose and brought water to sit beside me.

"Um, let me know if you need anything, big brother."

"Alright."

The meal that Serena carefully prepared by hand... I absolutely loved it.

"Serena manages the money, providing Stella with coins to spend each month."

"Uh! And you, brother?"

"I'm fine. Buy whatever you two desire. I'll replenish your funds when they run low."

"…"

Serena's cheeks flushed crimson as she twisted her waist.

"I wish to marry you, brother."

This girl…

Should I reprimand her once more with a firm smack to her backside?

"I'm envious of the stepsister who will marry my brother. Right, Stella?"

"…Humph. What's there to envy? We're already family."

Indeed, we are family.

Part of the reason I indulged in purchasing enhancements for my girlfriend's abilities was the potential for personal gain.

It sets this investment apart from the money I've given to family members, as I foresaw a return on it.

Of course, I receive something far more valuable than money in return: my sisters' affection and love.

I, too, enjoy being the chief provider in this household.

My beautiful stepsisters regard me as the head of the house, making it all the more gratifying.

"Ah! Brother, I'll take care of the cleaning. Don't touch a thing."

"Perhaps I could offer some assistance."

"Men don't typically do things like this. Go to the living room and relax."

A smile lingers on Serena's lips.

Her devotion to me and taking such joy in doing the odd jobs. I can't force myself to help her.

Instead, I…

Hold Serena tightly in my arms, gently pat her, and stroke her head.

"Oh…."

Serena seems delighted in my embrace.

"Thank you, Serena."

"Yes… Oppa…."

"I need to unpack, so I'll go upstairs first."

"Let me know if there's anything I can help you with."

I can't ask for help from someone who is already assisting me.

I tenderly kiss Serena on the forehead and head to the second floor.

It's so wonderful to have a caring sister at home. When I lived alone, even after eating,

I was slow to clean up, so there were always dishes piled up in the sink.

Serena is incredibly diligent; the house is always spotless, and there isn't a speck of dust to be found on the floor.

It's no wonder she's in charge of the family's finances.

'Let me put this here.'

I began by clearing out the remnants of (former) Sang-hyuk's presence in the room. I removed all the ill-fitting, smelly clothes, and it felt refreshing inside. There was no time to sort through the heavily soiled garments; I decided to simply discard them all.

And then, I caught a glimpse of Stella's lovely blonde hair through the open door.

Peeking.

"Stella?"

"I'll help you, big brother."

Serena assisted with the chores, while Stella helped with the organization. I truly was a fortunate older brother.

"Did you buy clothes?"

"Yes. I'll wear this at home."

"Will you launder them? I'll be back."

Stella kept herself busy, and thanks to her, I was able to finish organizing things more quickly. I took care of pushing aside the display case and disposing of (former) Sang-hyuk's belongings.

'There's so much trash.'

I tightly secured the waste in 50-liter pay-as-you-go bags and disposed of them one by one. Among the discarded items were numerous explicit magazines. Since the academy locker already contained a plethora of such material, I threw it all away. They were of no use to me anyway.

Upon returning to the first floor, the sound of the washing machine working tirelessly filled the air. Serena had nearly finished tidying up and was in the process of untying her apron.

"I'll help too, brother."

"Almost done. Don't worry about it."

Smooch, smooch.

I exchanged cheek kisses with Serena. Up until this point, it had been a sweet sibling moment, but then Serena's gaze crossed a boundary.

This was a temptation.

"…"

Don't give me that look, filled with desire.

The instant our eyes met, I pressed my lips against hers. It was a forbidden and sticky kiss, one that should never have transpired between step-siblings.

Ah, Serena's mouth is so delectable...

Slurp, slurp, slurp.

I pressed my lips against Serena's and entwined our tongues passionately.

"Mmmm… Huh… Hmmm…"

Serena looked slightly taken aback.

"Giving such a lustful kiss to your little sister..."

"Ah~"

As I opened my mouth and let out a soft 'ah' sound, Serena embraced me and returned the kiss.

"Churu, churu… Mwah… Mwah… Your little sister can't resist your kiss, brother.

Serena nibbled on my tongue, savoring it with delight.

As he gently caressed her slender back, he exchanged saliva with Serena.

*Chup… chup… chup… chup… chup…*

*Choo-Loop… chup…*

Suddenly, they heard footsteps descending the stairs, and they quickly pulled away from one another. Serena wiped the saliva from her lips with her arm, feigning as if nothing had happened. Her hair was slightly disheveled, and her cheeks were flushed.

"Brother! I have something to tell you. Please come to my room later."

"Uh, sure."

It seemed he hadn't revealed anything to Stella. He held the upper hand. Once he confirmed that Stella had gone back up the stairs, he whispered,

"… What should we tell Stella?"

"I'll leave it up to you. You can say, 'Serena has been helping me with sexual matters for a while now,' if you want."

"The kiss we just shared wasn't about sex. You know that, right?"

"Then?"

"I kissed you because I liked you."

What was he saying? How did he end up making such a statement? He felt embarrassed and wanted to die, but it had the desired effect.

"Brother, I like you too!!"

Serena embraced him.

Is it really okay just because the outcome is good? I ended up saying things I should never say to my younger sister. Serena spoke as she gently rubbed her body against my cock.

"Lying down with you, I want to keep... doing naughty things, hmm."

"…"

"Is it not allowed? Oppa…"

"What if Stella finds out?"

What if Stella gets twisted again? Am I the only one worried about this?

"Even if we get caught, we have to be caught well. Oppa, don't worry. Stella will be happy to take turns with your cock."

"Shouldn't I be pulling myself together now?"

I don't know what's right anymore.

"Why? We like you, Oppa. We like you enough to think it's okay to do naughty things with you."

So…

What would happen if I were to say okay? Leaving aside the pangs of conscience, my cock just keeps getting harder.

"It's not good... This is definitely a bad direction.

"I won't disturb you. Today, I'm getting closer to Stella. Oppa! You can do it."

But wouldn't it be truly dangerous if we became closer?

a little while later.

My footsteps led me toward Stella's room.

'I took a shower.'

What is she trying to tell me? I feel nervous at her door.

What kind of emotional change has Stella experienced since our passionate encounter?

"S-Stella has decided to become your slave!"

… What sort of fantasy is this?

It must be because of the cat costume Henna sent an hour ago.

"Phew…"

I took a deep breath and knocked on Stella's door.

Knock, knock.

"Come in…"

I could hear Stella's slightly damp, sultry voice from inside.

The atmosphere felt different from when we were in the infirmary.

Stella's room was clean, emanating a pleasant scent. It was filled with large, huggable dolls ideal for cuddling up with in slumber.

"What are you looking around for?"

"It feels like my first time seeing it. Stella's room."

"Of course. Did you think I'd let a pervert like you in? Into my room?"

But why am I allowed in now?

"Ah, don't worry now. I've dispelled all the protective barriers."

"…"

Room… Uh… Barrier…?

Could I have been electrocuted just now?

Stella sits timidly on the bed, waiting for me as she confesses such a monumental secret.

Who invented dolphin pants? What a beguiling item.

Stella's firm yet tender thighs and long legs stretch coolly beneath the bed.

"Is your ankle okay now?"

"Yes."

No scars remain, and it seems to have healed completely.

As expected, a world with healing magic is truly different. My back healed quickly after being injured as well.

I quietly sit down next to Stella.

"What do you want to say to me?"

"…"

It appears difficult for her to speak.

… It's difficult for me, too.

"Don't be so bashful. Haha. I've already done everything except having sex with Serena."

I can't say that!!

Stella doesn't know what transpired between Serena and me.

So.

The indiscretion in the infirmary must have been an incredible event for Stella.

'…Haha.'

I'm sorry, Stella.

I merely treated your loving gesture as an erotic event.

In the world of "OnaAka," some women boldly approach you, like Reida, asking if you'd like to explore their intimate parts, while others are delicate heroines who require a more subtle approach.

I know I shouldn't just pounce on her and take her, but... Is it the overwhelming scent of feminine pheromones that fills the room? Stella's naughty younger sister's aroma saturates the air, strangely stimulating my cock.

The atmosphere, ripe with sexual possibilities, urges me on. My cock begins to slowly grow erect.

"Is it... because of what happened in the infirmary?"

"Ugh…"

"Stella?"

"I'm so frustrated!"

Stella suddenly plops down on top of me. Oh no, Stella's buttocks are making contact with my cock!

"If I keep squirming like this, I'll die of frustration."

"Stella?"

Stella snuggles into my embrace, then swiftly lifts her head. Every emotion of Stella's is etched on her lovely face. Her eyes glisten slightly, as if begging for something!

Her furrowed eyebrows seem to say, "I hate to admit it, but what can I do if I've fallen for you?" This is the essence of a younger sister!

"Yes, I like you. Any complaints?"

"None."

"Because I did that, I can't make excuses anymore. So, I'd rather admit it openly."

"Do you like me, Stella?"

"I like you! I like you! I like you! So what if I like you? Until recently, I had been full of resentment, hurling harsh words at you. But now, things have improved. What should I do?"

Oh dear.

With the ebb and flow of emotions, please don't press your buttocks against me... Stella!

Though the squirming itself is truly beneficial to the health of my cock,

It's not appropriate for this situation!

Stella kept coming into my embrace, pouting.

"I only... helped you out because your cock was so hard it was uncomfortable! Because I'm your sister. That's allowed, right?"

"Is that really allowed? It's not supposed to be."

"Ah, anyway…! I have no regrets! I have no intention of turning back."

"I like you" is absolutely overflowing!

It's so like Stella to not know what to do with it and wrap it up in anger.

Serena had been straightforward in her affections from the moment we first met, unlike Stella.

But I couldn't bring myself to rebuke her.

"I like you too, Stella."

I embraced her tightly from behind, causing Stella to melt into my arms. The once restless girl now quietly heated up within my embrace.

"Ah. Ugh…"

"I think I truly cherished both Stella and Serena because they were my younger sisters."

"That's right? I must be a sister who is too much for a D-class brother like you."

Stella hastily corrected herself.

"I might be doing it a bit now, but... Don't be smug. You're still my older brother, no matter how amazing you become, right?"

"It's alright. I don't mind if Stella is D-class."

"Why are you so considerate?"

Wasn't confirming each other's feelings enough? At that moment, Stella firmly grasped my finger.

"…Brother."

"Hmm?"

"What if Serena finds out?"

"What?"

"That I touched your cock and did naughty things... What if Serena finds out?"

… ….

Had they already discovered our secret?

Asking such a question would be pointless.

"Is it because of me that we can no longer be a family?"

A sharp pain pierces my heart.

What in the world was I so worried about?
