Somehow I Ended up Dating the Perfect Female Classmate, but My Sister Found Out and They're Turning Into Yanderes - Chapter 95-96

Chapter 95: Digging Into the Domestic Violence

““““……””””

The four of us—me, Rinka, Ayuka, and Fuzuha—eat our yakisoba in total silence.

Summer festival yakisoba really is different from the frozen kind. It’s fresh and hot, and the taste is addictive.
But in this heavy atmosphere, nobody can actually enjoy the flavor.

“W-well… it ended kinda early, huh?”

Fuzuha breaks the awkward silence again.
Man, she’s the youngest here but she’s seriously the most reliable.

Compared to her, Ayuka and Rinka… nah, if I’m being honest, the least reliable one is definitely me.

“…We didn’t even need the yukata.”

Looks like Rinka is still pissed about being forced to wear one.

Actually, she probably just wants to complain about Satsuna.

By the way, Satsuna is upstairs right now putting away her dress.
She’s that refined young lady, after all.
She’d never allow any stains or wrinkles on her precious dress, so she’s probably being super careful even while taking it off.

“But it’s fine, right? Summer break is almost over anyway, and Satsuna’s gonna head back to the dorm soon.”

Like Ayuka said, this is the last week of my final high school summer break.

Once second semester starts, Satsuna will have to go back to dorm life.
Actually, why did she even come home for a whole month?
Isn’t homecoming usually just for Obon?

“I’m not exactly wishing for Sister to hurry back to the dorm or anything.”

“Liar. You’ve looked super uncomfortable ever since Satsuna got here.”

Rinka definitely wants her gone as soon as possible.
Ayuka might not say it out loud, but inside she’s probably singing “go home” on repeat.

“By the way…”

Ayuka suddenly gives me this slightly pulled-back look.

“Everything Satsuna was talking about earlier… the stuff she did to you… is that true?”

“…It’s true.”

There’s no point trying to dodge it now.

“That’s… isn’t that straight-up domestic violence?”

Whoa, I never expected to hear that word come out of Ayuka’s mouth…
Did Ayuka suddenly get interested in DV?
If so, feel free to test it out on my body anytime//

“You knew about it…?”

“…Today was the first time I heard the details. I knew Sister kept calling Kiyoto a useless dog or a pet animal, but I thought it was just her usual sarcasm toward him. Still…”

I guess it makes sense that Rinka never noticed until now.
Nobody would ever imagine their own sister was doing SM play with their brother.

“B-Brother… does that mean even during this summer break Satsuna did awful stuff to you…?”

“W-well, that is…”

“You don’t have to answer if you don’t want to. I pretty much get it now…”

Of course it’s true that Satsuna pampered me in all sorts of ways during break.
But that kind of thing is normal between me and Rinka, and I don’t think it’s something the family needs to treat as a problem.

“S-sorry!!!!!!”

Suddenly Fuzuha stands up and bows her head to me.

“It’s because I called Satsuna on the phone and told her to come home.”

“H-hey, you don’t have to apologize, Fuzuha. I don’t hate the affection I get from Satsuna at all.”

“Eh? You don’t hate it?”

Fuzuha looks completely caught off guard.

…Crap, I blurted that out in the heat of the moment.

“What did you just say? Kiyoto, you don’t see Sister’s treatment as suffering?”

“Well, um…”

Aah, I made it complicated by saying something unnecessary.

“What are you two so shocked about? It’s not like this is new—Brother’s always been a masochistic pervert who gets excited by Satsuna’s play.”

So Ayuka had already seen right through my true nature.

“……”

Fuzuha goes quiet after hearing that word from Ayuka.

“What do you mean?”

“Rinka, did you seriously not realize Brother is an insane masochist?
Well, I guess that makes sense. You’ve never done anything like that with him.”

There was that one time Rinka suddenly kissed me out of nowhere, though…

“Remember when you forced your tongue into his mouth? He looked super happy.”

“Forced my tongue…?”

Oh no!
When they questioned me about the time Kirino and Rinka forced a kiss on Ayuka, I never mentioned the tongue part!

“…This is the first I’m hearing that you violated Kiyoto’s mouth that violently.”

“Heh~ So Brother didn’t tell you about that.”

Hey, hey!? Why is Ayuka suddenly in such a bad mood too?
Did she want me to tell Rinka the full deep-kiss details just to tease her?

“…Kiyoto, explain yourself.”

“I’d also like to know why you didn’t properly tell Sister.”

Come on, I’ve been getting dragged around by a leash the whole festival. I’m tired, you know?
Isn’t it a little childish for both of you to gang up on me like this?

And right then

“My, what’s all this commotion about?”

Satsuna, who had finished changing out of her dress, came down at the perfect moment.

…This might be the first time Satsuna has actually saved me in the proper sense of the word.

Chapter 96: Last Playtime With My Beloved Dog

“My, Brother, you’re already back in my room before your owner… what a good boy.”

After I got out of the bath, I was waiting all alone in Satsuna’s room when she came in.

Thinking back now, during this summer break it feels like I spent more nights in Satsuna’s room after she came home than anywhere else.

“I feel a little lonely. Today is the last time I’ll get to see you tied up with a leash in my room, Brother.”

It’s the night of August 28th.
Only three days of summer break left.

And tomorrow Satsuna has to go back to the dorm.

I bet all my other sisters are secretly happy about that fact.

Even Fuzuha, who called Satsuna back, is feeling pretty guilty right now.

“What time are you leaving tomorrow?”

“I just need to be back for the night roll call, so I’ll head out around evening.”

“I see…”

Just so there’s no misunderstanding… I’m super sad about this!!!

When I first heard Fuzuha called her back, the fear of getting trauma-level stuff done to me was stronger than the happiness of being bullied again.

But during this summer break, at least nothing on the level of a chastity belt happened.
Instead she did all kinds of things that directly tickled my masochistic side.

I really think Satsuna understands my kink better than anyone.
On top of that, she “forces” me into exactly the kind of play that makes me happy.

“I thought I’d finally get to spend time with my beloved dog Brother… time really is crueler than I expected.”

No kidding.
I was hoping to get way more intense play during my last high school summer break, but it’s already coming to an end.
Time always gets in the way of my kink.

“Brother, once school starts you’re planning to do impure heterosexual acts with Kinui again, aren’t you?”

Her wording is full of malice, and we haven’t gone that far yet, but yeah, it’s probably gonna happen eventually.

“…As I thought, that woman isn’t right for you, Brother.”

There’s unusually strong emotion in her voice right now.

“She looks at you the same way I do.”

“What do you mean?”

“Like she’s warmly watching over her cute little pet.”

I’m pretty sure Kirino once said she fell for me because she got excited watching a weak guy like me desperately struggling.

…Yeah, that makes Satsuna’s point kinda valid, and actually she and Kirino have something in common.

“A pet belongs only to its owner and doesn’t wag its tail for anyone else. That’s the law of nature.”

Wait, first time I’m hearing that.
Pretty sure that’s just common sense inside yandere SS stories, not an actual law of nature.

“Kinui is trying to steal what is mine. The most adorable thing in the world that I’ve spent so long training to my tastes.”

Satsuna’s words are coming out faster and faster.

“To have my carefully trained property taken by some random woman who just showed up… it’s extremely unpleasant.”

The tyrant side of her is starting to show more clearly.

“No, come to think of it, it’s not just Kinui who’s trying to steal what belongs to me.”

I know that better than anyone.

“Rinka and Ayuka are both aiming for you too. They’re trying to lay their hands on you without my permission.”

Yeah, since I’m completely Satsuna’s trained property, the owner’s permission is obviously needed.

“There seem to be way too many greedy women around you, Brother.”

I think so too.
Right now there’s one of those women standing right in front of me.

“Once I go back to the dorm, they’ll probably start an all-out war to make you theirs.”

…I just hope it doesn’t turn into another police-level incident like before.

“The fact that I, the one who claimed you first, can’t take part in that war… is incredibly frustrating.”

Right now Satsuna looks like she’s letting her true regret spill out from the bottom of her heart.

“…Brother, may I ask you something?”

Satsuna leans her face close to mine and locks eyes with me.
Her gaze is so intense it doesn’t allow me to look away.

“…Won’t you come with me?”
