I’ll be there.
“Were you in the living room, big brother?

Protagonist: “// I’ve been in the living room for a while now.

“I see. I thought you were in your room. You scared me.
You know what?

Protagonist: “What?

“Did you hear what I just said to myself?

Protagonist: “// Yeah, a little bit.

Did you hear me? I was just reading a message from a friend.
“I just got a notification on my phone saying we should hang out sometime! Nothing weird about that.
“Right?

The main character: “Marina!

“Oh, my brother, no way. Why?

Protagonist: “Why, you’re the one.

“That’s my line. Wait a minute.
“I’m wearing jeans and a blue T-shirt.
“You’re the one who picked me!

The main character: “Yeah, but I didn’t think you’d come.

It’s my line! I didn’t think my brother would book our restaurant.
“Well, this is JK reflex. Do you know what you’re doing?

The main character: “How can I make a reservation without knowing what I’m doing?

Do you really know what you’re doing? You’re going to do this and that with me in uniform. Do you understand?

Protagonist: “I know, I know.

You know what I mean? Hmm. Hmm.
I’m starting to feel embarrassed saying that to myself (sigh).

Protagonist: “Yes.

“Oh, good. There’s a super delicious sweet. Let’s go.

“Hmmm, isn’t that cool? I’ll post it on social media later.
“Oh, yeah.
Big brother, look at me.

Protagonist: “" What?

“Ew.
“Heh. I got my first picture of my brother.

Protagonist: “Don’t take pictures without permission.

“Hey, why are you so grumpy? Didn’t you like being photographed? If you don’t like it, I can delete the picture.

Protagonist: “"You don’t have to delete it.

I knew you’d say that. I was hoping you would say that. I was hoping you would say that." “Oh, maybe you’re embarrassed, not grumpy?

Protagonist: (sighs in pleasure)

The main character: (letting out a sigh of pleasure) “You can feel it just by licking it? You’re so cute, big brother.

Protagonist: “"Don’t make fun of me.

“I’m not teasing you. I’m simply happy.

I’d like you to tell me more about your brother, (takes penis) mmmm, mmmm, mmmm, mmmm, mmmm.
I want to know more about my brother.
