The Case Where I had S with My Girl Friend Three Times

Throw All Your Common Sense About Lovers Away

—the day after Touya had sex with Iko.

Slowly and quietly.

Touya opens the door of his house with trepidation. It’s a little past seven in the morning.

The reason why Touya is opening the door quietly is because…Touya told his little sister that he would be home a little late, but he ended up going home in the morning.

It’s Saturday, Shio shouldn’t be up yet…

“Why didn’t you say you’re home, Nii-san?”

“Uwaa!?”

The moment Touya entered the living room, his little sister said so.

Shio is sitting on the table with a mug in her hand and a smile on her face…

“S-Shio…”

“Yes, I’m Shio-chan, nii-san’s most adorable little sister in the world.”

“……”

“Why aren’t you reacting as usual Nii-san? Please react as usual.”

Usually, Touya would have made some kind of retort, but now he can’t even do that.

Touya’s head is full of what happened last night.

‘Nhnn, Touya…Touya…”

Iko’s eyes when she looks at me.

Her exquisite face when she feels good and pleasured.

Her embarrassed face.

Her sweet voice whispering in my ear.

‘Cum…Touya…a lot inside me—’

AAAHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHH!!!

“Nii-san?”

“I’m going to lock myself in my room for the rest of the day—!!”

“Wait, Nii-san!?”

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

“And that’s why.”

“I see…”

Iko-san, please don’t look at me as if you’re looking at garbage! As I said before, it can’t be helped!

Me and Iko are sitting next to each other in the living room, Shio is sitting in front of us talking about what I did that day while drinking a cup of tea.

“Really, you don’t have to be embarrassed just because you stayed the night at Iko-san’s house.”

“I-I’m not embarrassed!”

I’m not embarrassed, rather I’m panicking because there is just too much going on my mind.

“I’m sorry Iko-san. Nii-san is such a virgin.”

“Eh…ah…yeah…”

“……”

…normally I would say ‘What’s wrong being a virgin!’ B-But, I did it, I’m not a virgin anymore.

Iko seems to think the same thing as she awkwardly avoids eye contact with Shio.

“But…it’s hard to believe that the two of you are still not dating.”

“…w-why?”

“Of course because the two of you are a great match…and on top of that, a boy and a girl sleeping under the same roof? I’m not sure what to expect. Ah, or maybe—did you two have sex?”

““!?””

Iko and I both stiffen up.

Why is my little sister so sharp…

Shio smiles as she sees our reaction. I think she notices something.

“I see, I see…I think my hunch might be right. Hey, Nii-san. You do know that I take care of our laundry, don’t you?”

“Ah, yeah…”

I usually give my uniform and other clothes to Shio for cleaning.

“I like to smell Nii-san’s clothes. Nii-san’s smell is calming.”

“……”

What should I do…eh, wait a minute, why was my little sister sniffing my uniform?

“I understand that Iko-san’s scent will be on Nii-san’s jacket because he was staying at her house, but the fact that even Nii-san’s shirt and pants smell like Iko-san…that means there was something about Nii-san taking off his clothes in front of Iko-san… In other words, you two did it ♪”

What Shio said is certainly true. But…is my little sister a police dog!? Is my little sister a pervert that likes to smell her brother’s clothes!?

“Nii-san, how many times did you have sex with Iko-san?”

“You shouldn’t ask that with a big smile on your face!”

“Oh, you don’t deny it. Bingo.”

I guess she found out. Shio is laughing out loud at my reaction.

Iko who has not spoken since a couple of minutes ago, is blushing in read as she looks down. I think the remembered the things we did.

Shio doesn’t stop interrogating us.

“The two of you had sex with each other, right?”

Kokuri, Kokuri.

“You had sex with someone who isn’t your girlfriend, didn’t you?”

Kokuri, Kokuri.

“Then why don’t you just go out with her?”

Neither Iko nor I shook our heads at Shio’s words.

“The two of you did it, right? Ah, is the relationship not progressing because Nii-san is an insensitive scum? Fufufu~”

I feel bad for holding the answer to Iko’s confession, but as I said before, I just can’t bring myself to give Iko a half-assed answer.

“That’s why the relationship between the two of you will remain the same until Nii-san can give you a proper answer. Right, Iko-san?”

“Yeah…that’s right…”

“I knew it. My brother is very serious in a weird way.”

“…you’re sharp, Shio.”

I really underestimated Shio.

Then, Shio sits up straight and look at us with straight eyes.

“Nii-san, Iko-san. Throw all your common sense about lovers away and go out with each other. Please date each other.”

Shio’s tone of voice is very serious.

Even Iko and I sits up straight at her words.

“Why does Shio-chan wants us to…why do you want me to be Touya’s girlfriend?”

After a short pause from Iko’s question, Shio begins to talk again.

“Of course I want Iko-san to be Nii-san’s girlfriend. I believe that Iko-san is the only girl for Nii-san, because whenever Nii-san talks about you, he has a very nice smile on his face.”

“…! I-I see…”

Seeing Iko blushing makes me embarrassed too.

“So…will the two of you date each other?”

“……”

Both Iko and I glance at each other’s faces and don’t say anything. We’ve been like this since a while ago.

I feel bad for Iko if we decided to go out like this—

“Ah, I’m such a light mouthed person.”

“…? Shio?”

Shio gets up from her seat and starts to walk around the room.

“I’m so light-mouthed that when I leave this house, I’m going to tell my neighbours that there’s a boy and a girl who won’t go out with each other even though they’ve done it.”

“Hah!?”

Shio glances at us as she said so.

Wait, stay calm, I don’t think Shio will make a joke out of this…

“Ahh, if Nii-san doesn’t say he will go out with Iko-san within this ten seconds, I will leave the house.”

No, no, no, there’s no way, right…?

Suddenly, someone tugs the sleeve of my shirt.

It’s Iko.

Iko is shaking her head as if urging me to say ‘we will date each other’.

“Then, I’ll start counting down now. Three, two—”

“Where did the seven seconds go!? I-I will date her!”

“Date who?”

“…me and Iko…we will date each other! We will be lovers!”
