Chapter 4 – I Reported Masturbation to My Sister

Smart.

“… Sister. It’s me.”
“The door is open, come in.”

Before opening the door, I took a deep breath.

How long did you have to worry before coming to this room?
I thought and thought about it, but it only wastes time and only builds up stress.
Because this was a question for which there was no right answer from the beginning.

I made up my mind and opened the door.
My older sister was sitting in front of her dresser, doing her hair.
As if she was getting ready to go to sleep, she was wearing only a thin slip.

Black underwear is visible under the slip.
My sister always looked like this at home, but today it felt particularly sensational to dress like that.

“Why are you here so late? You thought you were missing it from the first day and tried to find it.”
“… Sorry.”

I wanted to tell you to stop doing this.
I wanted to tell them to stay as normal older sisters and younger siblings like before.

However, when I saw my sister, instead of the words I practiced several times, the words I was sorry came out first.

“It’s okay. Are you going to masturbate now?”
“…”
“Aren’t you going to answer me?”

My sister stares into my eyes through the mirror.
I swallowed dry saliva and nodded.

“… Huh. I will do it from now on.”
“Okay. Are you thinking of your older sister properly? Got it?”

Saying that, my sister stood up from her seat.
Then he put his hand on her waist and pulled down the panties she was wearing.

I was startled by my sister’s sudden action and turned around.
Taking off her panties in front of her younger brother out of the blue, what the hell is your sister thinking?

“Ruler. Today’s daughter.”

Something light lifted the top of my head.
Daughter feeling… Surely, it’s not what I think, is it?

Carefully hold something on your head with your hand.
I could feel the soft feel of the fabric.
When I checked it with my own eyes, it was sure to be the panties my sister was wearing.
Passionate Red. Her panties, embroidered with luxurious patterns, were half transparent.

My sister just called it today’s daughter’s feeling.
Just like I did yesterday, today it would mean to ejaculate in these panties.

My older sister was sitting on the bed, her legs crossed, staring at me blankly.
Are you enjoying yourself watching me panic?
I stammered, trying to squeeze the defiant words out somehow.

“Whoa, sister. Something like this…”
“Why? Don’t you like it?”

My older sister smiled and crossed her legs in the opposite direction.
The white thighs exposed under her short slip attract my attention.

Besides, my sister is not wearing panties right now.
If I just look, I might see an important part.
When she thought about that, her heart started pounding.

But it’s the Bermuda Triangle.
If I take my eyes off it, I will drift forever.
To avoid such a situation, I mobilized all my mental strength to look away.

“… Okay. Can it be cheaper here?”
“I know. And after that, be sure to come check it out. Got it?”
“Test…”

Does that mean you’re going to check if you masturbated properly as your sister told you to?

… What does your sister want to do?
Is it just that he wants to see me embarrassed, or is there some other purpose…
I don’t know what the hell my sister is thinking.

But even if I have complaints, I can’t rebel against my sister.
If my sister told me to do it, I had no choice but to do it.

* * *

After leaving my sister’s room, I returned to my room and locked the door.

Following yesterday, this time has come again.
Time to masturbate with my sister’s underwear.

I took off my pants and lay down on the bed.

“Under…”

A sense of relief that you have come to your own space.
And at the same time, shame about what to do next.

But I have no other options.
It would be best to stop thinking about it and end it quickly.

I grabbed the panties with both hands from her sister and tried to spread them.
It was dirty panties.
Almost half of the panties were made of mesh, so the important parts seemed to be exposed.

Is your sister always wearing these panties?
Are you wearing it to show off to someone?

My sister also had a lot of dating rumors, but I’ve never heard of her actually dating anyone.
But all I don’t know is that she might already have a boyfriend.

A boyfriend who will show you how to wear these panties.
When I thought about that, my heart felt tight for some reason.

Maybe it was because I wore it after taking a bath, but the fabric softener smell was stronger than yesterday.
I use the same fabric softener for my clothes, but somehow it felt different from my clothes.

“Sister…”

I remember my sister taking off her panties.

If I hadn’t looked away at that time, I wouldn’t have been able to see it properly.
Even when I was sitting on the bed, if I moved my eyes a little, I would have seen it.

I started masturbating while drawing in my head the part I hadn’t seen.

-Smart.
Knocking on my sister’s door

My sister’s panties were now in my hand.
My sister’s panties with a lot of my semen on them.

A sense of shame makes my heart suffocate.
Her hands are heavy
Panties are not heavy. The weight of sin in my hands was heavy.

Just standing in the living room felt like committing a sin.
I felt like I just wanted to go to my room and hide.
But there was no response from the room.

I forced my mouth open and let out a voice.

“Sister. I’m done.”
“Come in.”

After hearing my sister’s answer, I enter the room.
Since when did it become a chore to go into my sister’s room like this?

My older sister, who was lying on the bed, saw me and pulled her body up.
In the meantime, I slightly averted my gaze because I felt like I could see something I shouldn’t have seen.

“… And came.”
“Okay? Give it to me.”

My sister holds out her hand to me.
… Does this mean putting out the panties?

Now my sister’s panties are full of semen from me.
To be honest, I don’t even want to touch it.
Can I give this to my sister who has mysophobia?

“What are you doing? I won’t give it sooner.”

As I hesitated, my sister urged me.
I couldn’t help but put my sister’s panties, which had been gathered together, on top of her hand.

“Let’s see. How cheap were our ancestors?”
“Nu, sister.”

My sister spread her panties casually in front of her eyes.
The sticky, white filth clinging to her red panties was clearly visible.

“It was very cheap. The smell is awful too. Did you feel good?”

I said nothing and hung her head.
My face felt like it would explode in shame.

“Hmm. The seonhu is wrapped in the inside of her panties. Do you know what that means?”

My older sister asks with a relaxed smile.
The inside of your panties?
Is there any meaning to that?

“The act of ejaculating on the inside of your panties. The meaning of this act is ‘I want to impregnate the other person.’”
“What… !”

Of course, I have no idea what that means.
I just did it without thinking.

“That’s right~. Did you want to impregnate your sister?”
“Oh, no, I didn’t know that…”
“Originally, these things are unconscious and real. It’s a kind of psychological test.”

That’s a lie
Who in the world would create and prove such a psychological test?

My older sister smiled happily and asked me.

“How are you, Seonhu? Do you really want to get your sister pregnant?”
“Oh no, I…”
“Whoops.”

My older sister quietly strokes her belly.
As if there was a baby in it.

I don’t know what my sister’s behavior means.
But for some reason I couldn’t take my eyes off her hand.

“Yes. If I sleep wearing these panties like this, won’t I get pregnant? If the sperm are healthy before and after, they will ride up her vagina and reach her womb, right?”
“… What are you talking about, sister? Uh, can’t it be? Something like that…”

Lips dry up.
I don’t know why my sister is saying this.
Why are you wearing dirty panties in the first place?

No, this is obviously something my sister was just joking about.
To make fun of me
There’s no way an older sister with such a strong sense of mysticism could wear panties soiled with semen.

So no need to panic.
The more embarrassed I am, the more happy my sister will be, and the pranks will get worse.

“Or how about wearing this and running to the police station crying?”
“Sister!”

I thought I would never panic.
However, I couldn’t get past her sister’s words.

“If you analyze the DNA of the semen on your panties, you will immediately know who it is. Then, Seonhu will become a rare sex offender who raped his older sister, Jin So-young.”
“Well, if you did that, your sister would…”
“Yeah right. Neither I, nor Mum, nor Miso will ever be able to carry their faces in this country again. Ah, that’s sad I would have thought that my house would fall apart due to the adoption of children from other people’s houses.”

I had no choice but to listen to my sister while shaking.

My family suffers because of me.
What she said was literally the most horrific thing I could think of.
It’s hard to breathe just imagining it.

“So, come early tomorrow. If you listen carefully to your sister, you won’t tell anyone. Do you understand, right?”

A thin finger brushes my ear lobe.
It felt like a lion had licked my neck.
