It’s Not Like I Like You, Sister
Graduation at the magic academy always coincides with the arrival of the New Year.
Since graduation isn't simply a matter of having spent a long time at the academy, the ceremony is held on a grand, almost extravagant scale.
I had stepped foot into the school for the first time in a while, and standing right in front of me was Belial.
“So this is the magic academy where Runi attends.”
Because I had only ever told her stories about my school life, she looked around with intense curiosity, as if everything were fascinating.
“The mana here is quite dense.”
“That’s probably because of the Mana Crystal up there.”
On the roof of the magic academy, there exists a Mana Crystal where vast amounts of mana are condensed.
It is responsible for the barrier surrounding the academy and plays a major role in maintaining the school's structure.
“Doesn't something like that need to be hidden?”
“It’s fine. There’s a barrier around the Mana Crystal that can only be broken by a state-certified 1st-class mage.”
“They’ve put up an incredibly sturdy barrier.”
“Runi!”
Students scheduled to graduate have no reason to come to school before the ceremony.
Naturally, opportunities to interact with classmates have dwindled.
As I was chatting with classmates I hadn't seen in a while, their attention naturally drifted toward my sister.
“Ah, this is my close sister, Belial. I’ve told you a lot about her, right?”
“Hello, Sister. I’ve heard so much about you from Runi.”
“Is that so? What kind of things did Runi say about me?”
“She said you were incredibly pretty, kind, gentle, and a sister she respects.”
“Hey…! W-when did I ever…!”
The exposure by my classmates led to teasing from my sister directed at me.
Perhaps because the compliments were the kind that anyone listening couldn't help but smile at, she listened to them with a smirk and repeated them back to me.
“So that’s how it is. Runi thinks I’m pretty, kind, gentle, and someone to respect.”
“Th-that… that was only when I thought you were human.”
“So you’re saying that’s not the case now?”
“Obviously!”
I turned my head sharply and walked away with heavy, forceful steps.
-Thud!
“Eek…?”
Just then, a disaster occurred where I tripped over my own feet.
As the ground and my face drew closer, my sister wrapped her arm around my waist and caught me.
“Thanks, Sis…”
-Smooch!
She lifted my waist to make me look at her face, then, very naturally, pressed her lips against mine.
The kiss itself didn't bother me.
It’s an act she does so often that I consider it part of my daily life.
The problem was that she had kissed me at the front gate of the magic academy, where so many people were gathered.
“Oh my, what’s that?”
“Youth, huh.”
“Isn’t that Runi?”
“Looks like she’s dating that person.”
As the murmurs I couldn't possibly ignore reached my ears, my face turned red enough to explode.
“Ugh… S-sister…”
“Hmm?”
“H-how long… are you going to keep doing this.”
We were at a distance where I could feel her breath far too clearly.
Catching me when I fell was fine.
But why did she suddenly have to kiss me…
“Cute.”
With those words, she tried to kiss me again, so I hurriedly pulled away from her embrace.
“Whew…”
“Runi, wait up.”
I walked forward, looking only ahead, leaving my sister, who followed me with innocent playfulness, behind.
All while keeping my hand pressed against my chest.
At some point, my heart had started racing.
So much so that my heartbeat was being transmitted clearly through the hand I held against my chest.
“Runi, I said wait for me.”
My sister, who had followed me, took my hand.
At that moment, my heart began to beat even faster.
At first, I thought it was because of the kiss that had taken place in a crowded area.
But that didn't seem to be it.
After all, the physical contact with my sister had made my heart rate climb even higher.
Doesn't this mean my heart started racing violently because of my sister's kiss?
“Runi.”
“Have you been well, Runi?”
While I was lost in thought, I ran into my parents, who had come for my graduation.
“Mom, Dad! It’s been a while!”
“You seem a bit more mature since the last time we saw you?”
“Oh, really?”
“Hello, Mother, Father.”
“Belial, we are always grateful to you.”
“Thank you so much for taking such good care of our Runi.”
After greeting my parents for the first time in a while, I headed toward the main auditorium where the students were supposed to gather.
But before that.
“Sister, I’m going to the restroom.”
“Mm, alright.”
I stopped by the restroom for a moment.
Not to relieve myself, but because of my heart, which hadn't calmed down since the moment her lips touched mine.
“Haa… why is it like this?”
I sat quietly on the toilet and placed my hand over my chest.
My heart was still beating at a faster pace than usual.
“It’s not like I like my sister.”
Anyone would judge this reaction as one that appears when you like someone.
Come to think of it, this had happened before.
The moment she held me in her arms and whispered words of love.
I had the same reaction then.
“Ugh… I don’t know.”
In this state, I didn't have the confidence to face my sister.
Because my heart would surely go even more insane.
“Is it because of her face?”
It would be strange if I didn't feel a flutter, even as a woman, when looking at her face.
Her face is, after all, national treasure-level.
“No, but she’s a demon…”
I reminded myself over and over that she was just a demon with a normal-looking exterior, but this body simply wouldn't listen to me.
After closing my eyes and taking a few deep breaths to calm down as much as possible, I stood up from the toilet.
Just as I opened the door and stepped out.
“Sister…?”
Belial was standing right in front of me.
She gave a small smile and stroked my cheek.
My heart, which I had barely managed to calm, started racing like crazy all over again.
“Wh-why are you here…”
“Runi, your face is red?”
“I-is it? I don’t know why. L-let’s go now. If we don’t, we’ll be late… Mmph!”
The hand that had been stroking me slowly cupped my face.
Immediately after, her lips and mine became one.
“Mmph…”
“Slurp…♡”
Her tongue entered between our joined lips, wrapping around mine and refusing to let go.
-Creak!
I couldn't resist the force pushing me back inside.
Naturally, I ended up in the same space as my sister, and the door locked firmly.
“Slurp… why is our Runi’s face so red?”
“Th-that… Sister… I think we’ll be late for the graduation ceremony…”
I couldn't bring myself to push her away, so I barely managed to let out a voice that sounded like I wanted to crawl into a hole.
-Squish! Squish!
“Hnggg…♡”
Before I knew it, my sister’s hand had slipped inside my skirt and was stroking my pussy over my panties.
“N-no… not here…”
“Is the place the problem, or is the time the problem?”
“Obviously… both…”
-Squiiish!
“Hyaaa-mmph♥”
She pushed my panties aside, and two fingers slid deep inside at once.
A moan threatened to burst out roughly, but my sister’s mouth blocked it.
“Slurp… Slurrrp♡ Mwah…♡”
“Hnggg… Hyaaa…♡ Mmm… Slurrrp♡”
Contrary to saying no, I was already matching her tongue.
-Squish, squish, squish, squish!
“Hnggg♥”
It wasn't the massive cock that always filled my pussy, but my sister’s thin, long fingers moving.
Repeating the motion of curling and straightening, pressing firmly against the vaginal wall.
Of course, the stimulation was lighter than when a cock was inside.
“Mmmph♥ Hnggg♥ Hmph♥”
Every time she pressed against the vaginal wall, moans leaked out continuously.
“Mirei, have you seen Runi?”
“No, I haven’t.”
“Where did she go? She just disappeared.”
Voices of my classmates came from outside.
They seemed to be looking for my whereabouts while washing their hands.
Would they know that the Runi they were looking for was having her pussy fingered by my sister in a toilet stall?
Would they know that I was in a state where my love juices were overflowing, soaking my legs?
“Mmmph♡”
“Hmm?”
“What’s wrong?”
“I thought I heard a strange sound.”
“It must be your imagination.”
“No. I definitely heard it.”
-Step, step!
At the moan I accidentally let out, the sound of footsteps drew closer.
A clear shadow was visible under the door.
This meant my classmates were right in front of us.
-Squiiish!
“Mmph…♡”
In a situation where she should have pulled her fingers out of my pussy, my sister pushed them in even deeper.
Not stopping there, she flipped her fingers and rummaged through my pussy.
“Sniff, sniff… I think there’s a strange smell here?”
“Isn’t it just the smell of the restroom?”
“I guess so.”
“Mirei, now is not the time for that. It’s really starting soon.”
“Ah, right!”
The shadow clearly revealed under the door faded away along with the sound of receding footsteps.
“Phew…♡”
“We can go now, Runi.”
-Squish, squish, squish, squish! Squiiish!
“Hnggg…♡ Hyaaaaaa♥”
-Spluuurt!
As if signaling the finale, she kept flipping her fingers and digging into my pussy, and unable to endure it, I sprayed a large amount onto the floor.
“Haa… Hnggg…”
“Slurp… Runi is the prettiest when she comes.”
-Smooch!
My sister, who was licking her fingers with a satisfied face, announced that our time was up with a small kiss.
My legs gave out, and I slumped down onto the toilet.
“Do fingers feel good, too?”
“Ugh… Sister’s fingerrrs… feel good…♡”
“Let’s go to the graduation ceremony now. Your parents will be looking for you.”
“Hnggg…♡ I-I can’t walk…”
Because my pussy had been roughly fingered while I was standing, my legs showed no signs of regaining their strength.
Perhaps acting for my sake, my sister pulled up my half-fallen panties properly.
And she even wiped away the love juices that had soaked my thighs.
“Runi.”
“Mm…?”
As I looked up at her with half-lidded eyes, a soft touch came to stroke my hair.
She just stroked it without saying a word, looking down at me.
A small smile was playing on her face.
I have no idea what she’s thinking.
Whenever I try to figure it out, it feels like I’m sinking deeper into a swamp.
