The dinner menu featured pasta, prepared by Serena herself.
"Enjoy your meal, brother."
"Thank you for the food."
It was delicious. The noodles' doneness and seasoning were precisely to my taste.
Serena was skilled at cooking as well. Impressive.
The familiar aroma of garlic wafted from the heated pan.
"I prepared gambas as well. Here, I've got some soft bread too, so it'll be nice to eat together."
"Mmm…"
Since it was already in his mouth, he simply nodded repeatedly.
"Brother, say 'ah'."
"Ah~."
Munching away…
He diligently ate whatever Serena fed him.
Stella observed them from the side with a look of disgust.
"What's going on? Why are you talking like that?"
"Stella, you too. Say 'ah'."
"…When did you two become so friendly?"
Stella begrudgingly accepted Serena's food, even as she complained about their sudden closeness.
They stuffed their cheeks with food like hamsters and chewed, their gazes fixed on Serena.
"Uhm, since this morning?"
Cough! Cough!
He nearly spat out all the food he was eating.
"Brother, please eat slowly."
The black-haired younger sister handed him a glass of water with a beaming smile.
…In a way, she seemed even scarier than Stella.
Perhaps it was because they shared secrets that went beyond just stealing glances or taking pictures of her underwear.
"…Something seems off."
A cold sweat trickled down his spine.
"Stella, you also opened your heart to brother today, didn't you?"
"Open your heart? Who on earth to whom?"
"We ended up sharing a meal like this, didn't we?"
"That's true…"
Stella glared at me.
"The one who was always locked in their room has come out. That's the only difference."
Me? Ah, I see.
The role of the recluse must have belonged to Koo Sang-hyuk.
Stella was always confident, so she most likely dined with Serena.
From Stella's perspective, I, the new Sang-hyuk, am an uninvited guest intruding on the happy family's mealtime.
"There's no reason to stay locked up anymore. If you want to see Stella's panties, just ask her to show you."
"Who's going to show you?!"
"I've already seen them today."
Startled!
Stella clenched her thighs together and glared at me indignantly.
"No fighting, both of you. Isn't it nice to gather and eat like this?"
"Right. Fine."
"Besides, if a brother wants to see, a sister can at least show her panties, right?"
"That's not the case."
"What are you saying? Have you lost your mind, Serena?"
My rapport with Stella is seamless.
Serena clapped her hands in delight.
"Wow! Our chemistry is perfect, isn't it?"
"…"
"…"
The timing of closing their mouths was the same. It's normal for one to react like Stella when asked to show their underwear. If they think they can show it… It's actually scarier to ask them to do so. It feels like they might really show it.
"Ah, brother. You have a lot of laundry. Are you going to wash them all?"
"No, I'm going to throw them away. I tried using hydrogen peroxide and baking soda, but they didn't work."
What on earth did they get on themselves for the stains to be so stubborn? It was a total mystery.
"School uniforms? It's a waste to throw them away."
"The size doesn't fit. I… grew a bit taller last night."
"Hmm… I'll try to alter it for you!"
"It'd be quicker to buy a new one. How much does a uniform cost?"
"About 900 coins?"
…
To afford one, they'd have to defeat eighteen goblin hordes? They checked the number of coins deposited on the student ID.
[Kim Sang-hyuk]
[Coins held: 54]
'This won't work.'
Would they be summoned to the student council room again if their attire continued to be improper while they tried to earn more coins?
I was not absolved of my guilt. My punishment was merely suspended due to mitigating circumstances.
It was a conclusion even a child could understand: should an accident occur in the meantime, I would face aggravated repercussions.
"Please, Serena."
"Leave it to me, big brother! I'll take care of it."
"I'll get up first."
*Swish.*
Stella placed the dishes she had eaten from in the sink, then ascended to the second floor.
We followed her with our eyes.
"Do you think there's a possibility of reconciliation?"
"Stella gets lonely easily. If you keep reaching out, she'll come around soon enough."
"I can hear you!"
If only she would come around.
I hoped for peace in our home…
There was nothing better than having beautiful younger sisters who followed me willingly.
A short while later.
"Big brother, can we sleep together?"
'This might be following me too well.'
At bedtime, I stood before the door, my vision growing hazy as Serena swayed her waist.

…I never wanted to know that my sister was a hexagonal Onahole.
Dressed in a translucent shirt with black lace underwear, I'm even more unsure of where to look.
Serena, tightly embracing her pillow, gazes up at me with moisture-filled eyes.
If the very orchestration of this scene feels contrived, is it merely my imagination playing tricks on me?
This is a blatant seduction.
Or is it not?
Could it simply be that my thoughts have become depraved?
'…Would close siblings share a bed?'
I should be discerning. Kim Sang-hyuk.
But as an only child, I genuinely don't know.
I reflect on my experiences during holidays, when I used to sleep in a mixed arrangement with my cousins.
That's not much help.
I can say with certainty that the atmosphere back then was never this sexual.
My cousins appeared as creatures teetering somewhere between monkeys and humans, so entwining while we slept never provoked any thoughts.
…But just the idea of sleeping beside Serena…
"Oppa… I'm scared to sleep alone."
I gulp.
Her skin looks incredibly soft, evidently still damp from her recent shower.
Serena's captivating purple eyes, positioned within the dimly lit corridor,
radiate a mysterious allure as they shimmer gently.
"Even after growing up, you're still afraid to sleep alone?"
"Yes."
"…Come in."
Serena, granted permission to enter the room,
With a playful smile, she suddenly leapt into my embrace.
Tightly!
"Hehe!"
"You…!"
"Am I a child, scared of sleeping alone? Huh, oppa?"
She's not a child, but a grown-up, and that's the problem!
Ah, no bra?
Unable to resist, I became aroused as Serena pressed her breasts against me and even rubbed them.
Serena smiled alluringly, as if confirming her charm.
Try as I might to shake her off, she wouldn't easily let go.
Serena, tempting me while rubbing her breasts.
"Mmm~ oppa, why do you keep stepping back?"
"S-Stella might see… "
"Haha, it would be a real mess if Stella found out that you and I already had sex."
"…What sex?!"
It's not sex!
"You said it was a mistake too."
"Oppa, are you trying to evade responsibility?"
"It's not that. It was an accident! Even for the sake of your future husband."
Serena stood tall and looked up at me.
"…You already knew?"
"What…?"
"My brother's… the sensation when it fills me completely, reaching to the very root… The reaction I showed when I clenched tightly, the feeling of unity we experienced when we became one."
"…"
"At that time, I felt that I had no choice but to become your woman… In my little sister's nursery, you made me swear, remember?"
Each of Serena's words makes me dizzy.
Is it really like that?
Is there truly no turning back?
I felt like my intelligence was gradually decreasing as she rubbed her breasts.
"Am I really a virgin? Brother?"
"…Ah, ugh."
"Did you take me earlier… or not?"
"No."
Like that.
It's dangerous if I don't force myself to think that way.
Our relationship.
"But…"
I grabbed Serena's delicate shoulders.
"Ah, brother?"
"If you don't want to make a mistake, I'll take full responsibility."
If that's how Serena feels.
I'm…
"Your brother, your lover. Can I be your boyfriend?"
"…"
Serena's face looked lost, as if intoxicated.
"...Let's go talk to Stella about what happened between us."
Serena snaps out of her daze, as if my sincerity had reached her.
"Ah, no! Oppa… I was just joking because I found it amusing to see you flustered…"
"There are other things to joke about! Do you really want to get scolded?"
Phew…
I breathe a sigh of relief inwardly.
It seems I'm still okay as her older brother.
"I'm sorry. I didn't mean to act like I had found your weakness…"
"A mistake… right?"
"Yes. It was clearly an accident, no matter who looks at it. Don't feel guilty, Oppa."
That's true…
Losing one's virginity by simply falling down is absurd…
That should be considered a no-count, humanly speaking.
"…Was what you said earlier also a joke?"
"...What do you mean?"
"You mentioned something about going down to the root…"
Serena could only give a sheepish laugh.
...It must have been a joke.
My handsome cock surely wouldn't possess an evil effect like 'once a woman tastes it, she can't turn back.'
Right? Oh, Goddess?
To Serena's future husband, Serena is a true maiden, in both heart and body.
Please, let it be something like this. I shudder at the thought that I might have ruined Serena's life.
"Now we can sleep together, right? Brother."
"…Huh? Is that so?"
"Yes. Everything is settled. All that's left is to sleep with my trustworthy brother!"
"…???"
Huh? Is this right?
Led by Serena's hand, we enter the bed together.
Seeing Serena happy, there shouldn't be any problem…right?
A dark room after turning off the lights.
Feeling Serena's skin and body heat, we become entwined.
Serena doesn't seem to mind my erect cock touching her; instead, she snuggles closer in my arms.
"I'm glad you're my brother."
"Well, we haven't known each other for that long…"
"But we've seen each other for years."
Ah, right. From Serena's perspective, that's true.
"Anyway, out of all the brothers I've known for years~, I like the brother I saw today the most."
"…"
I didn't think there could be more unsettling words than Stella's "Die, brother."
"Brother. I like you."
This time, it felt like my brain was melting.
After being entwined with one another for some time, I gently touched Serena's bangs and cautiously inquired.
"…Does that mean you like me as an older brother?"
My face flushed with heat.
Why was I asking my younger sister such a question?
What if she liked me as a man? Would I go on to touch her right away?
Serena was fast asleep in my arms, seemingly at ease.
'…'
Sigh…
We had agreed on 'older brother.'
Serena was merely elated to have an older brother to dote on her.
If I had been serious and tried to make a move, she would have had the same reaction as when I had just grabbed her shoulder.
So…
As a man, my duty was to not touch her.
Even if Serena were to give me room as vast as the Pacific Ocean, I wouldn't lay a finger on her.
'…This is the hardest thing I've done today.'
It was quite a predicament with my cock being so aroused.
