Somehow I Ended up Dating the Perfect Female Classmate, but My Sister Found Out and They're Turning Into Yanderes - Chapter 66-67

Chapter 66: One More Person Attending Cram School

“So, why is Satsuna-neesan tagging along?”

“Is it a problem if I come with you?”

As usual, Ayuka and I rode our bikes to cram school.

But today, my bike was really hard to pedal.

The reason? Satsuna, sitting right behind me on the saddle.

Why do modern bikes have a structure for two people if riding double is supposed to be banned?

“Brother, you’re pedaling too slowly. Ayuka’s leaving you behind.”

“W-Well, with two people, it’s harder to pedal—”

“So, you’re saying my weight is heavy?”

“N-No, not at all!”

If she did something from behind, I could get seriously hurt, so I had to keep Satsuna in a good mood.

“Still, I’m deeply moved to see you going to cram school, Brother.”

Yeah, right.

“But, Brother, if it’s about studying, I could teach you step by step.”

Step by step…//

No, no, bad idea.

If my “son” gets excited now, it’ll be dangerous.

“Is Satsuna at the top of your class too?”

“Of course. I scored higher than even the seniors in national mock exams. Though, that’s why some of the dorm seniors dislike me.”

Being disliked in a girls’ dorm sounds chilling just thinking about it.

To be clear, the “bullying” we’re talking about is sexual, okay?

Don’t get that wrong.

“Would you like me to invite you to my dorm sometime, Brother?”

“…What, for real?”

I almost ignored it since she said it so casually, but that’s a big deal, isn’t it?

Inviting me to an elite girls’ school dorm!?

Of course, I’m going!!

“Yes, I’d love—”

“Stop! Hold on, Satsuna-neesan! What are you saying!?”

I was about to agree eagerly, but Ayuka cut me off.

“I’m just talking about inviting Brother to the Shinkai Girls’ Academy dorm.”

“That’s not the point! That’s not allowed! What’s the point of a girls’ dorm then?”

“It’s fine. With Brother’s body, no one would treat him as a guy.”

Hey, what does that mean?

Am I androgynous or something?

If so, I’d happily dive into a yuri situation, but does she just mean I’m scrawny and not seen as a threat?

“That’s not the issue! And you, Brother, why are you agreeing? Do you want to get assaulted for real—”

“AAAAAAAAHH!!”

I shouted to drown out Ayuka’s voice so Satsuna wouldn’t hear.

“What’s wrong, Brother? Yelling like that all of a sudden.”

D-Dirty!?

“N-No, I just remembered I forgot something.”

I signaled to Ayuka with my eyes to be careful.

She signaled back with her eyes, apologizing.

“A-Anyway, Satsuna, you’re in your uniform again today?”

I quickly changed the topic, but this was something I was curious about.

Yesterday, Satsuna slept in her uniform, and this morning she said,

“I’m going to change here now.”

I hurriedly looked away, and she teased,

“If you want to see me naked, it’s fine.”

Even so, seeing a refined lady naked might ruin her image, so I tried to look away as much as possible (not saying I didn’t sneak a peek).

After changing, she was back in her uniform.

“Isn’t it hot wearing that uniform?”

“It’s hot, but in dorm life, we weren’t allowed to take off our uniforms no matter the season, so I can handle this heat.”

Is that really an elite girls’ school dorm?

I was ready to go along with the idea earlier, but if it’s got strict rules like some old-school Spartan academy, I don’t want to go.

No, wait, maybe in such a strict environment, girls starved for romance might use me, a guy, to let loose…

No, what am I thinking?

I have my beloved girlfriend, Kirino-san.

Look, I’m even seeing a hallucination of Kirino-san right in front of me… wait, hallucination?

“Good morning, Kiyoto-kun.”

“Huh!? Kirino-san!?”

“Yes, why are you so surprised?”

I was so caught up in talking and imagining with Satsuna that I didn’t notice we’d reached the bike parking area.

“N-Nothing. Good morning, Kirino-san. But why are you at cram school today?”

“That’s what I want to ask you… I bet Ayuka, the brother-obsessed girl, dragged you here, right?”

“No, I didn’t drag him!”

Yeah, you totally threatened me to come.

“I just came to use the study room today.”

“Oh, I see.”

Kirino-san and I run into each other a lot, for better or worse.

“By the way…”

Kirino-san looked behind me.

“Who’s that girl with white hair?”

Chapter 67: Chaos at the Bike Parking Area

“Who’s that girl with white hair?”

Kirino-san pointed straight behind me, like a little girl spotting a ghost.

Well, Satsuna’s presence is hard to ignore for Kirino-san.

Totally expected.

“Brother, is this the girlfriend you mentioned?”

“Yeah, I told you about Kinui Kirino-san.”

“I see. Nice to meet you, Kinui-san. I’m Satsuna Nuregami, the eldest daughter of the Nuregami family.”

Satsuna greeted her elegantly, stepping back with her right foot and lifting her skirt’s hem.

She’s definitely been trained at that fancy girls’ school.

She’s so refined on the outside, but behind closed doors, she makes her pet (me) lick her feet.

Am I the only one charmed by that gap?

Yeah, probably just me here.

“Nice to meet you, Satsuna-chan. You’ve probably heard from Kiyoto-kun, but I’m Kirino, his girlfriend.”

“Yes, yes, I know, Kinui-san.”

Kirino-san probably declared herself my girlfriend right away because Satsuna’s my sister—and the eldest—so she’s on guard.

“So, what’s Satsuna-chan doing here today?”

“I just came to observe my sister and my pet-like Brother’s private life.”

“Uh, Kiyoto-kun’s… a pet?”

“Yes, my beloved dog.”

…This is way beyond expected.

Who calls their own brother a dog right after meeting someone?

But she’s totally right.

I’m Satsuna-sama’s loyal dog.

Next time, not just her feet, but maybe her armpits…

“Still, I can’t help but notice Brother’s bad taste.”

“What do you mean?”

“Well, for my dog’s girlfriend to be someone who looks like she’s into paid dating… oh, pardon me. Someone who looks so shameless.”

“Sis, I totally agree.”

Ugh, I’m done caring what happens now.

“…That’s a bit rude, don’t you think?”

“I’m just stating my opinion. No need to take it personally.”

“I’m not bothered at all.”

Your eyes are screaming that it did bother you, Kirino-san.

And the worst part? Satsuna’s insanely sharp and notices these things right away.

She’s already noticed.

“Sis, this woman’s just Brother’s fling, so you don’t need to say stuff like that.”

“Can you not butt in, Ayuka-chan?”

Alright, this is getting out of hand, so I’ll step in—

“Oh, Brother. Do you think a dog can just walk away from its master?”

Yes, I understand.

I understand, so please stop pulling the skin on my back.

It hurts more than grabbing my neck.

This is abuse!

I’m reporting you to an animal protection group!

“…I thought the eldest sister would be more decent. To think she’d be so rude at our first meeting and call her own brother a dog.”

“Still better than a fling like you.”

“Can you stop acting so high and mighty, Ayuka-chan?”

“Now, now, both of you, please stop fighting.”

“You don’t get to say that, Sis!”

“That’s not something you should say, right?”

Wow, amazing.

It’s the first time I’ve seen them agree on something.

“So, not ‘paid dater,’ but Kinui-san.”

“Yeah, that was definitely on purpose, right? My name doesn’t sound anything like that.”

Honestly, Kirino-san’s being pretty mature for not snapping yet.

Man, where she pinched me really hurts.

She’s such a sadist, she probably knows exactly where to pinch to cause pain.

She’s so perfectly my kind of master…//

“So, how far have you gone with Brother? With a name like that, I bet you’re already physical, right?”

“…Kiyoto-kun, sorry. I’m at my limit. If we stay in this bike parking area… you know? Can we all just go inside the cram school?”

“Y-Yes…”

…This is bad.

I’ve never seen Kirino-san so close to snapping, her face all red with anger.

…I hope if she breaks, she turns into a violent girlfriend.
