“After class, the duel will take place in the auditorium~! If you’re scared, feel free to run away! Ohohohot~!”
Even after Orteza finished her declaration and returned to her seat, everyone’s attention remained focused on us.
However, when the homeroom teacher loudly cleared her throat, everyone quickly turned their heads away.
Tsk.
It’s like watching a well-trained dog.
They’re so spineless, swayed by every little thing.
“The class representative will be decided through a duel between the two of you. If anyone has an objection, please raise your hand.”
Who could possibly raise their hand in this situation?
The influence of the Noxfer Viscountcy is said to rival even that of a Duke.
Anyone who dares to oppose her would be marked for sure.
‘…What a cunning teacher.’
My first impression of the homeroom teacher was far from favorable.
She deliberately didn’t stop Orteza’s actions, and even now, it feels like she’s trying to pit me and Orteza against each other.
“Then, let’s begin our first lesson. Today, we’ll be covering the basics of magical attributes.”
The lesson that followed was something I had already learned exhaustively from Alyssa.
Alyssa, surprisingly, had taught me everything in great detail. The teacher’s explanations were almost identical to hers.
“Good work, everyone.”
Clatter-.
“Wait! Alyssa!”
As soon as the first class ended, Alyssa quickly got up from her seat, hugged me, and rushed off somewhere.
The discomfort and shame of being hugged by my younger sister made me want to break free, but there was no way I could overcome Alyssa’s monstrous strength.
“Sister, no one will be here.”
Eventually, Alyssa dragged me to the academy rooftop.
The rooftop was so high that the ground below looked distant, and as Alyssa had said, it was completely empty—not a single person or even a chair in sight.
“Alyssa… why did you bring me to a place like this? You need to tell me the truth.”
“Sister.”
“W-Wait!”
Bang-.
“A-Alyssa…”
Unfortunately, my body seemed to have learned from past experiences, as I instinctively flinched when Alyssa slammed her hand against the wall.
How many times has this been now?
Being pinned against the wall by Alyssa…
Every time this happens, Alyssa changes, and it’s starting to get scary.
Zing-.
“Why.”
“Ugh…”
Alyssa’s low, cold voice carried an eerie intensity.
Even though she had dragged me here and was clearly angry, I had a vague idea of why she was upset, which only made me feel more pathetic.
“Didn’t you listen to what I said…?”
“A-Alyssa… I had a good reason…”
“I clearly told you not to fall for such cheap provocations.”
I had no words to defend myself. It was me who fell for the low-level provocation, and it was me who put the family’s honor on the line by not backing down.
“…I’m sorry, Alyssa.”
“That’s not enough.”
“Huh?”
Even though I had sincerely apologized, Alyssa didn’t let me go.
No, not only that, but she stepped even closer, pressing herself against me until I could feel her breath.
“Sister… you told me not to leave your side, right? So, I’ll do anything to protect you.”
“That’s only natural…”
“Then, this time, I’ll have to punish you.”
Tap, tap tap-.
“Huh!? W-Wait! Alyssa, what are you doing!?”
Alyssa began unbuttoning the uniform I was wearing.
Slowly, the uniform came off, revealing my undergarments and bare skin.
A wave of shame washed over me.
I tried to stop her, but before I knew it, both of my wrists were pinned by Alyssa.
Being held down like this while she undressed me felt like I was being humiliated, and at some point, the fear began to outweigh the shame.
“A-Alyssa… stop…!”
Alyssa’s blue eyes had already darkened, and she looked just like she did during those strange moments I’d seen before.
I knew that at times like this, Alyssa wouldn’t listen to anything I said, but all I could do was plead in a voice that sounded more like a whimper.
“Sister… do you hate it?”
After completely removing my top and exposing my undergarments and stomach, Alyssa asked as if it were the most natural thing in the world.
I was about to answer, but her next words left me speechless.
“I… hate it too.”
Alyssa was shedding transparent tears… one drop… then another.
Why… do you look sadder than me, the one being punished, Alyssa?
“I want to protect you.”
Swish, swish-
“Ugh…!”
Alyssa’s fingers brushed against my navel, and I let out an involuntary, lewd moan.
I quickly bit my lip to stop any more from escaping, but it was already too late—Alyssa had heard it.
“That’s why… I won’t hesitate to do things you hate.”
Squeeze-.
“Ah…”
Her long, slender fingers dug into my navel.
Moving slowly, as if scratching the inside, her fingers created a strange sensation that made me unconsciously release my lip, which I had been biting.
“Sister. Please listen to my request. If you don’t, I’ll punish you every time.”
“What… ah… are you…”
“No matter what happens, I’ll always be on your side. You promised… not to push me away, right?”
Squeeze, squeeze-
“Stop…”
Disconnected.
A promise I had made to Alyssa long ago.
As her older sister, I couldn’t break a promise to my younger sister, so I had no choice but to quietly endure Alyssa’s punishment.
Why can’t I control my temper…?
I tried to hold back, but something inside me boiled over, and I couldn’t resist.
“…It’s all red now.”
“T-That’s enough… right? Alyssa…”
How many minutes had passed?
My navel, relentlessly tormented, was now swollen and red, just as Alyssa had said.
A throbbing pain spread through me, but the relief that the punishment was over outweighed the discomfort.
“Yes. Now, I’ll heal you. Sister Amy.”
“W-Wait! Stop!”
Before I could stop her, Alyssa knelt down and brought her lips to my navel.
Slowly, she stuck out her tongue and began licking it, the wet, warm sensation sending shivers through me.
What is this? Is this part of the punishment? Why… is Alyssa… doing something like this…?
“Stop! Get… off me!”
I tried to push Alyssa away with my now-free hands, but she held onto my thighs with both hands, refusing to budge.
Meanwhile, she continued to lick my navel relentlessly, the sensation more ticklish than painful.
Slurp-
“Ah… ngh…”
Eventually, I gave up trying to push her away and resorted to covering my mouth to stifle any sounds.
Seeing that I had given up, Alyssa seemed to gain momentum, gripping my thighs even tighter and sucking on my navel.
‘This is weird… it feels so strange…’
Even though Alyssa had done something lewd in her sleep just this morning, at least that was unconscious.
But now, she’s fully awake… why is she doing this?
I’ve never heard that her saliva has healing properties before…
Slurp…
“Haah…”
Alyssa finally stopped after a few minutes.
My navel, thoroughly sucked by her, was now throbbing in a different way.
“Alyssa…”
“My saliva has strong healing properties. See, Sister.”
“What…?”
I was about to slap Alyssa’s stomach, but when I looked down, sure enough, my navel was completely healed—no trace of injury.
Not just my navel, but my entire body felt revitalized, as if energy was surging through me.
The usual lethargy and fatigue were gone…
“What is this…”
“Sister. If you get hurt, I’ll lick you anywhere. So, please try not to get hurt.”
I was about to get angry, but Alyssa’s confident tone left me speechless. The gentle, fragile Alyssa I knew… no, even the Alyssa who never dared to defy her older sister—where had she gone?
“Now, let’s go back. Sister Amy.”
Smirk-.
“Y-Yes, let’s go…”
In the end, I had no choice but to obediently follow Alyssa back to the classroom, overwhelmed by her presence.
Even after returning to the classroom, I was so dazed that the rest of the day’s lessons passed by in a blur.
‘Alyssa…’
My mind was completely filled with the image of Alyssa sucking on my navel.
I don’t want to admit it,
I absolutely, absolutely don’t want to admit it.
‘Ugh…’
Even now, a faint trace of that pleasure lingered.
‘What is Alyssa really after…?’
Sometimes, she’s like a sage who knows everything.
Sometimes, she’s like an innocent, untainted child.
Sometimes, she’s like a fragile younger sister longing for love.
I don’t know which Alyssa is the real one anymore. She’s even grown a little taller… and today, she…
“Haah…”
The memory of Alyssa pinning me against the wall earlier came to mind, and I let out an involuntary sigh.
For some reason, thinking about that Alyssa makes me feel strange.
“You! Are you listening to me!?”
“…?”
“The time for the duel has come! It’s time to show everyone your weak side~!”
“Ah… the duel. We were supposed to have a duel.”
“Had you forgotten!?”
I had completely forgotten about Orteza.
Right now, what’s important to me is Alyssa’s transformation, not some insignificant girl like her.
‘…Alyssa doesn’t seem to care.’
I glanced at Alyssa, but she was just smiling faintly, showing none of the intense reaction she had when Orteza first provoked us.
Does that mean it’s okay to fight?
I don’t want to risk Alyssa sucking on my navel again if I lose.
…No, what am I thinking, Amy?
The family’s honor is at stake.
I can’t run away just because I’m scared of Alyssa.
“Fine. The auditorium, right? Let’s go.”
“A-Alright… W-Wait! Don’t just leave me behind!”
Leaving a flustered Orteza behind, I headed to the auditorium.
As expected, Alyssa also got up from her seat and followed me, but unlike usual, she stayed a step behind.
“Sister Amy.”
“…What is it, Alyssa?”
“Please try to win without hurting the opponent too much.”
“If I ask why, will you tell me?”
“…I’m sorry. But I know you’ll win, Sister.”
After saying that, Alyssa didn’t speak another word.
Even when I looked at her, she averted her gaze, refusing to meet my eyes.
…I can’t keep letting Alyssa have her way like this.
When we get back to the dorm tonight… I’ll have to punish her.
