10 My Older Sister is Evil

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

Following yesterday, this time has come again.

The time I masturbated with my sister's underwear.

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

I feel a feeling of relief that I have come to my own space.

And at the same time, I feel shame about what I have to do in the next moment but there is also excitement.

I held the panties I received from my older sister with both hands and unfolded them.

They were sexy panties.

Almost half of the panties were made of mesh, so it seemed like even important parts were transparent.

Does my sister always wear panties like this?

Are you wearing it to show someone?

There were many dating rumors about my older sister, but I've never heard of her actually dating someone.

But I just don't know; maybe she already has a boyfriend.

She have a boyfriend, where she show him wearing panties like this.

When I thought about that, my heart felt uncomfortable for some reason. Let's not get deep into this feeling.

I used the same fabric softener for my clothes as my older sister, but somehow, this panty feels 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 clearly.

Even when I was sitting on the bed, I could have seen it if I moved my eyes just a little.

I started masturbating, picturing parts in my head that I couldn't see.

* * *

"Sister, I'm done."

"Come in."

After hearing my sister's answer, I enter the room.

Since when did going into my sister's room become such an ordeal?

My sister, who was lying in bed, saw me and got up.

In the meantime, I felt like I was seeing something I shouldn't have, so I slightly averted my gaze.

"I did it."

"Okay? Give it to me."

My sister holds out her hand to me. Does this mean giving up her panties? Fuck stupid me, of course she wants that.

Now, my sister's panties are covered in a lot of the semen I released.

To be honest, I don't even want to touch it.

Is it okay to give something like this to my sister, who has mysophobia?

"What are you doing?"

As I was hesitating, my sister urged me.

I had no choice but to put my older sister's panties, which were bunched up in a ball, on top of her hand.

"Let's see."

My older sister casually opened the panties in front of me.

The sticky white dirt sticking to the red panties was clearly visible.

"It's a lot. The smell is also terrible. It must have felt good?"

I said nothing and lowered my head. It's is somewhat embarrassing.

"Hmm. Rye cums on the inside of my panties. Do you know what that means?"

My sister asks with a relaxed smile.

The inner side of the panties?

Is there any meaning to that?

"The act of ejaculating on the inside of panties. The meaning of this act is 'I want to make the other person pregnant.'"

"What…!"

I have no idea that something like this exist. Really?

"I see~. Do you want to make me, your older sister pregnant?"

"Oh, no, I don't know about that..."

"Originally, this kind of thing is unconscious. It's a kind of psychological test."

That's a lie.

Who in the world creates and proves such psychological tests?

My sister smiled happily and asked me.

"What do you think, Rye? Do you really want to get your sister pregnant?"

"Oh, no, I…"

"Hehe."

My sister quietly strokes her lower abdomen.

As if there was a baby inside.

I don't know what my sister's behavior means.

But I couldn't take my eyes off my sister's hand for some reason.

"Yes. If I sleep in these panties like this, won't I get pregnant? If it's Rye's healthy sperm, it will travel up my vagina and reach my uterus, right?"

"What are you talking about, sister? Well, that can't be possible, right? Something like that..."

My lips are dry.

I don't know why my sister says this.

Why wear dirty panties in the first place?

No, this is clearly something my sister is just joking about.

To make fun of me.

There's no way a sister with such severe mysophobia would wear panties stained with semen.

So, there is no need to panic.

The more embarrassed I am, the happier my sister will be and the more playful she will be.

"Or how about putting this on and running to the police station crying?"

"Sister!"

I thought, never panic.

But I couldn't ignore my sister's words.

"If police analyze the DNA from the semen on my panties, they will know right away who it is. Then Rye becomes a rare sex offender who raped his older sister, Amara."

"Well, if you did something like that sister then..." I stopped speaking.

"Yes, that's right. Neither I, nor Mom, nor Lye will ever be able to carry our faces in this country again. Ah, it's sad. I never thought my house would be ruined by having someone else's child."

I could only listen to my sister.

My family is harmed because of me.

What my sister was talking about was literally the most horrible thing I could think of.

Just imagining it made it difficult to breathe.

"So, come early tomorrow. If you just listen to what I says, I won't tell anyone. Do you understand, Rye?"

A thin finger brushes my earlobe.

It felt as if a lion had licked the back of my neck.

I'm definitely sure, my older sister is evil.
