Chapter 11 – Let’s Study!

After school.

We’re in the go-home club, so we headed straight home. It’s not that I have no admiration for club life, but I prioritize my own time more. We are Generation Z, after all.

“Alright, let’s knock out the homework.”

Today we had math homework assigned at school. Having changed into casual clothes in my room, I pick up the workbook. Honestly, I’m bad with science and math and find them a pain, but putting it off will only make things worse later.

“…………”

That said, I don’t really feel motivated. For some reason, looking at numbers always makes me sleepy.

“For now, maybe I should relax a bit first……”

I lock my room door and pull out my beloved Sukebee manga from its hiding spot.

Changing the subject, rabbits have incredibly strong reproductive power. For example, in Australia, a few rabbits that were brought over escaped and, with no natural predators, multiplied into hundreds of millions in just a few years. Readers, don’t casually release invasive species into the wild!!

Anyway, I, who share the name of such a creature, also have very strong sexual desire. This is a necessary act. If I don’t do this, I might end up unleashing my wicked desires on Aku-nee or Auntie Midori…… nee-chan.

While making such excuses and opening the pages, Aku-nee suddenly called out to me.

“Hakuto-chan!”

“Gyaaaaah!?”

“You don’t have to be that surprised……”

“A-Aku-nee!? Why are you here!? I locked the door!”

“Well, picking it only takes one second. I like how simple the locks in this house are.”

“Don’t casually use lockpicking skills… Does the concept of privacy not exist for you, Aku-nee?”

“When it comes to Hakuto-chan, that kind of thing doesn’t exist…… Wait, were you in the middle of enjoying yourself? Geez! If you had just told me, I would’ve done quite a bit for you…”

Saying that, Aku-nee picks up my Sukebee manga and starts skimming through it.

“Ah, hey?!”

“Again with this stuff…… Hieh?!”

This book is the most extreme one story-wise among all the Sukebee titles I own. At first glance the art and cover look like pure sweet lovey-dovey moe, but the actual story can be summed up as “heartless.” The heroine girl is endlessly corrupted, both mentally and physically broken, her dignity trampled, and in the end she’s left in a state like the final episode of Gund◯m SEED. It’s a legendary manga in many ways. ……The girl with the wonderful smile on the cover turning into a complete wreck at the end really gets me going.

“…………I won’t say anything new about Hakuto-chan’s fetishes at this point, but…… Big sis is really worried about you… This content is a huge turn-off. Is this the kind of development that’s okay in an ero manga? This……? This is what gets you excited?”

“Reading someone’s Sukebee manga without being asked and then taking damage from it is your own problem…… At least praise me for not unleashing my twisted desires on you, Aku-nee.”

“You can unleash them, you know? I’d just like you to hold back a little.”

“No.”

“Well, whatever. Hey Hakuto-chan, let’s study together!”

Saying that, Aku-nee points at the math workbook. While pulling my pants back on, I look at her a bit suspiciously. She had already changed out of her uniform into casual clothes too — a T-shirt and mini-skirt combo.

“Study? You’re not plotting something, are you?”

“You have no trust in me……”

“How am I supposed to trust someone who picks the lock and breaks into my room?”

“Fair point.”

“……If you don’t do anything weird, it’s fine. Either way I have to do the homework.”

“Fufu…… That’s what I like to hear!”

“However, if you start sexually harassing me again, I’m kicking you out, okay?”

“Where does it cross the line into sexual harassment? What’s the boundary?”

“Why are you always trying to push right up to the edge……”

While feeling exasperated, I grab my own workbook, pull out the foldable table I had leaning against the wall, and set it up. Even if her brain is full of pink thoughts, Aku-nee is actually pretty smart. Studying together has benefits for me too.

Chapter 12 – The Movie Is Currently Receiving Massive Acclaim

This work contains spoilers for the theatrical version of Gund◯m SEED.

“……This problem here—”

“……”

“……For this part, you use this formula.”

“……”

“……Word problems look complicated, but if you calmly break them down, they’re easier.”

I thought she was plotting something, but once we actually started, it turned into a completely normal study session.

Aku-nee may act strangely, but she’s genuinely smart. That trait was fully on display this time, and we finished the homework smoothly and quickly.

“Amazing. Aku-nee, you’re really good at teaching.”

“Ehehe. It’s not that big a deal~”

Aku-nee puffs her chest out proudly. Cute.

“You might want to aim to become a teacher in the future.”

“A teacher, huh…… I hear it’s pretty black company vibes, though. Kamaitachi-sensei complains about it a lot……”

“It really is a harsh world.”

Leaving aside Aku-nee’s career plans, we finished the homework much faster than I expected. Now what?

“Want to take a break? I’ll go make some cocoa.”

“Yeah. Thanks.”

With that, Aku-nee stood up and headed to the kitchen.

Maybe I’ll watch some YouTube videos. My favorite creator posted a new one. Or should I watch a movie or anime? Our house has all the subscription services so it’s basically unlimited. Or maybe play some games.

While thinking about that, Aku-nee came back to tell me the cocoa was ready. She suggested we drink it together in the living room, so I left my room and went over.

There’s a TV connected to the internet there, so maybe we could watch some anime. We’ve been rewatching the Gund◯m SEED series together lately, especially since the movie came out.

Our family has always been huge Gund◯m fans. I think we’ve seen pretty much the entire TV series. Of course we also went to the theater as a family to see the movie I mentioned. Even though it’s a popular title, the fact that we still go watch movies together as a family even now that the kids are older shows how close we are.

By the way, in CE my favorite MS is Aku-nee’s Destiny while mine is Strike Freedom…… The fact that our tastes don’t quite match is still the same as always.

Aku-nee even displays the model kit of that machine in her room because she likes it so much. So after it and its pilot got major screen time in the movie, her brain was fried for a while.

She even tried to buy three more model kits and hopped between the local electronics store and toy shop, but everywhere was sold out and she cried tears of frustration. They didn’t even have the old kits from before the remake.

……Some of you readers know that pain, right?

＊＊＊

While drinking the cocoa Aku-nee made for me, we sat shoulder to shoulder watching the TV screen. Our parents are still at work. Since they’re a dual-income couple, until they get home at night, we kids have free rein.

On screen was the climactic mid-point of the second movie — the one-on-one duel between the previous protagonist and the current one in the snow.

“……”

It was an intense scene, but for some reason Aku-nee wrapped her arm around mine.

“What? You’re being really clingy.”

“This way it feels like we’re lovers. Sitting close and watching the same screen together.”

“……We’re not actually dating though.”

“You say that, but the fact that you’re not forcing me off shows you don’t totally hate it.”

“Well, that’s……”

Aku-nee rubs her chest against me. She then takes one of the Jagari○ potato sticks she brought out as a snack, and brings it to my mouth. I gratefully accept it.

“……Aku-nee, are you seriously not wearing anything underneath right now?”

After swallowing the snack, I ask what I was thinking. From the feeling, she’s probably only wearing that T-shirt.

“You noticed?”

“If I’m in contact with you every day, of course I can tell the difference between when you’re wearing a bra and when you’re not.”

“Hakuto-chan you perv.”

“You’re the one rubbing yourself against me……”

I say it with exasperation, but in truth I’m definitely getting excited.

“……?”

Something’s off. There’s a strange sensation. An abnormally strong sexual arousal. Sure, touching a girl’s body will naturally excite me, but this impulse rising up toward my stepsister is on a completely different, far more intense level than usual.

On the TV screen, the protagonists’ battle had just begun.
