After finishing up with Lushia, I headed straight back home.

"……Ah, Sensei♡ Welcome home♡"

Nanako, my high school girlfriend, came in holding Choobi, the puppy, in her arms.

"I'm home, Nanako. I'm home, Choobi."

I stroked the puppy's head, and he closed his eyes with a look of pure bliss. "……Goo."

Nanako stared at me intently through her black eyes. "……Goo."

...Apparently, she was doing it to me too. "Good girl. Good girl." "……Hehe♡"

I headed back to the living room with Nanako. "Welcome home! Welcome home, Onii-chan♡" "……Yeah. Bro, welcome back."

Akari in her apron and my younger sister Midori were waiting for us to come home. "I'll warm up dinner right away~" "Ah, yes..."

Perhaps because we had shared a kiss with Lushia earlier, looking at the two of them felt a bit awkward... That's what I was thinking when...

Akari stopped in her tracks.

She came striding toward me. "Wh-What's wrong...?"

Akari rubbed her nose against my chest, snuffling. Wh-what…? "Did you meet Lushian?"

How does Akari know I met with Lushian…?

"Figured as much~ That makes sense then~ ♡" Akari flashed a dazzling smile. ……I’ve learned my lesson.

When Akari gets angry, she smiles. I’ll be honest.

"Yeah, I went to see Lushian."

"I see, how about we have something to eat first? ♡ ……We can deal with the tribunal later." "Ah, uh…" Akari headed toward the kitchen. I changed into fresh clothes and returned. Nako and Midoriko were seated at the table.

Waiting for the food, I kept an eye on Akari’s mood.

I couldn't sense anything particularly unusual from her back…

But the aura of rage she had just radiated was overwhelming.

"Sensei, why is Akari angry?" Nako asked me.

"…Eh, Akari's angry?"

Midoriko widened her eyes in surprise as she asked Nako. "Yeah. It’s really…"

My sister must be able to read the room, at least when it comes to my little sister's mood. "I'm here!"

Shortly after, Akari places the dishes on the table. Thud. Well... he really went all out this time. "...It's hiru zaru sushi."

"It's summer, you know? Hot days like this, I figured we'd need to build up some strength."

There were four portions prepared just right.

Nanako and the others had theirs set properly, and so did I, and him.

I was worried it would be a meal where only one person gets to eat... "Well then, let's dig in~♡" "Thanks for the food!"

I picked up my bowl and downed some hiru zaru sushi. As always... damn, this is good.

"Eat it plain at first, then add some sansho pepper, and finally pour the dashi broth over it."

"...Honestly, Akari, your cooking skills are amazing, you know that?"

Impressed, Midori Lake devoured her food with gusto.

"Don't flatter me. I'm just training to become Karin's wife-in-law."

Akari flashed a bright smile and asked me something.

“Was your wife’s cooking tasty, huh ♡?”

“Ah… it’s really good. Thanks for always doing this.” “You’re so welcome~ ♡”

Akari said nothing. That silence was what made it even scarier...

Midori Lake ate as if unaware of the tension, while Naeko trembled.

“Ah, Akari...? Don’t get angry now, okay?”

“What? I’m not angry at all?” She was absolutely furious...

Although the meal was delicious... the pressure was unimaginable. He finished eating shortly after.

As barley tea was served for everyone, Akari opened her mouth to ask the first question. “Did you do it with Rushian?” ““Wha—!?!””

Naeko and Midori Lake wore expressions of sheer shock.

“While your wife was cooking at home and waiting for you?”

“No, wait, that’s a misunderstanding. I didn’t do it.”

“But you did meet with Rushian, right?”

"It was just... I stopped by to pick up the manuscript, and while I was at it..."

"So you went to collect the manuscript and gave Rurian a kiss?" "「Kiss!？」"

My actions were becoming increasingly clear in front of everyone…….

"P-please... k-kissing... n-no, no way..."

"...Brother, did you kiss her while she was working? You bastard? Huh?"

Nanako's face flushed red as she writhed around, "Nope nope, no I didn't."

Midori Lake had veins bulging on his forehead... tik-tik.

"Okarin, it's not like, it's okay. Since he's in a relationship with five of us anyway, it's fine to kiss Rurian who is his lover?"

Then why is he getting so worked up?

"But it's kinda... unfair, don't you think? Hey, what do the two of you think?" Akari asked Nanako and the others.

"I, I am that... um... jealou-s..." "Your sister is saying it's unfair too, see—" Akari cut her off. "What about Midorin?"

"...Ah, I also think it's unfair. Because... Ah, I also want to... do that with... Brother..."

Nanako and Midoriko both turned crimson. The two of them didn't look even remotely angry.

"Ahem. So, here's the deal: Karin is gonna have to kiss all of you~"
"Whyyy?!"

Me, Nanako, and the rest chanted in unison.

Wait... why are things ending up like this?

"You're everyone's property now, Karin~ If you've already kissed one of us, well, logic dictates you have to kiss the other four too, right? That's what the gods said?" Which god, exactly...?

Still, Akari really is possessive.

"Ahem, so Senpai, please start~"
"Eeh? Eh-eh-eh?!"

She turned red enough for steam to visibly waft off her head. No... yeah. That's probably right. "Maybe we should skip it. We're in public." "...Y-yesh ma'am."

Nanako let out a breath of relief.

Next, I have to talk Midoriko into letting us go...
"Midoriko... mmmph!"

As my sister turned away, she caught me off guard and pressed her lips against mine.
"M-Midoriko-chan?!"

She pulled back with a soft pop.
"Mmm... thanks for the meal."

Pe-co, Midoriko Lake bows her head.

"M-Midori-Lake-chan!... Y-Y-You shameless..."

Nanako says this, her face completely crimson.

But Midoriko Lake turns to the side with a composed expression.

"...B-Because you're gonna kiss everyone, right? So, so it's okay... right?" "I-I'm not..." "...Right?"

Midoriko Lake pushes her face closer, sui.

"...You kissed the other girls too, didn't you? Then... it's fine. I wanted to do it... Or were you uncomfortable?"

Anxiously, Midoriko Lake looks up at me. I must not let my little sister misunderstand. "I wasn't against it." "...Mm."

Blushing, Midoriko Lake averts her gaze.

Both of her ears were bright red. I had kissed my younger sister...

Until just recently, we had been ordinary siblings, but...

She used to kiss me with the casual affection of 'I love you,' but now she comes at it with a sense of shame.

I felt a mix of emotions as I realized how grown-up this was, compounded by the sense of sin from kissing my sister... My chest ached. "Alright, I'm up last~ ♡"

Akari stood up and swung her legs over, straddling my knees like she was riding a horse.

"W-Wait! A-Akari! That position is... kinda perverted..."

Honestly, if you saw it from the outside, we probably did look like we were having some shady time at a sketchy joint.

"That's fine ♡ If you want to jump straight into that shady play you're wishing for, I don't mind one bit~"

"I'm the one who minds... cut it out..." I tried to push Akari off me. But... "Eh-heh ♡"

Akari hugged around my neck and kissed me on the spot.

It wasn't anything like that passionate kiss we shared when we were alone before.

You might call it a peck.

She gently nipped at my lips in a quick kiss before pulling away. "..."

Compared to that ravenous, devouring kiss from that night, this was incredibly light.

"...And something way more intense is coming on our date ♡"

Akari whispered into my ear and gave me a pat as she winked.

Seriously... this girl really has both an angel and a devil living inside her... Akari hopped down from me.

"Does this satisfy you?" "«No way...»"

Dripping with an aura of anger radiating from behind, Akari and Midoriko said:

"We still have a trial pending regarding the fact that you kissed Lushia♡"

"I mean, I'm not saying it's wrong for lovers to kiss?" "It is allowed, but you're not allowed to do it. ♡" "What kind of logic is that..."

Midoriko said this while puffing out her cheeks.

"...Bro, when did you become such a playboy?"

"It's not like I'm actually a player or anything."

"...You kissed her, didn't you? That's so mean. I wanted to do that more..."

While the two of them were furious, Nana remained silent. "Nana... Nana?" "Nee-chan!"

Her face was bright red as she completely lost the strength in her body and slumped back onto the chair! Is s-she catching a cold or something!? "Nana!" "Kyuu..."

With her eyes rolling back in her head, Nanae was unconscious.

"I guess that was a bit too stimulating for your big sister?"

"Yeah, it really was...! Nanae! Hey, Nanae!"
