My younger sister is the woman who will become my slave.

An awkward atmosphere lingered in the cafe.

My sister and I were sitting at a table, having coffee with our masks off.

My sister and I aren’t super close.

At best, we ask each other if we’ve eaten.

And even then, my sister curses at me for everything,

and rags on me for not doing my job properly; to put it bluntly, she’s kind of a shitty person.

We like completely different things,

and we enjoy completely different things, but…

Why, of all things, did our sexual tastes have to match up perfectly in this crazy situation?

“You perverted bastard.”

“…Who’s the perverted bitch who flashed her naked body to a perverted bastard?”

“Th-that’s because I didn’t know it was you.”

“What’s the difference between a bitch who sends nude pics to a random guy and a bastard who doesn’t even know it’s his sister and sends sex jokes and asks to meet up?”

The conversation is a little too intense for a cafe.

But she’s the one who started the fuss, so there’s no reason for me not to respond.

I started the sex jokes first,

and my sister was the first to send nudes in response.

Doesn’t that make us even?

But if she weren’t my sister, she’d be perfect.

24 years old, about 159cm tall, D-cup with abs, Kim Jihye.

She’s also good at studying, so she succeeded in getting an internship.

But the problem is that her eyes are so fierce that she’s rumored to be a scary woman.

They said she’s so scary that guys can’t even approach her,

but whether it’s luck or misfortune, I didn’t see her face and only saw her body, and honestly, I’m horny.

But she’s my sister, and we live in the same house, so we can’t just satisfy each other’s sexual desires.

I’m a son of a bitch for getting horny for my sister, but she’s also a son of a bitch for taking nudes for a random guy.

“If I knew you were a pervert, I would’ve satisfied you.”

“…That’s fucking awful, a jobless bum after graduation is gonna hit me.”

“The bitch who got horny from chatting and sent nudes is saying that.”

“Ah, shit, that’s because I didn’t know your face.”

“So, if I cover your eyes and hit you, you’ll get horny? Should we go home and I’ll cover your eyes and hit you and we’ll bet on whether you get turned on or not?”

I was just going to finish my coffee and go home, but this bitch is really good at getting under my skin.

Shi-bal, I couldn’t get a job because the flu spread and hiring was blocked,

but anyone would get pissed if you nagged them about that.

It’s not that I didn’t work, it’s that society didn’t hire me, is that my fault?

I got pissed and scratched her nerves too, and she couldn’t even refute my words properly.

Yeah, I may not be as good at studying as you, but my mouth is top-notch.

With that… I made my sister horny, even though she’s my sister… I feel a strange sense of guilt.

“Fucking bastard. Let’s bet, shibal, what are you gonna bet?”

“What are you gonna bet? You’re obviously gonna lose, so do you even have anything to bet?”

“If I get horny from getting hit by you with my eyes covered, I’ll be your slave, shibal. Then what are you gonna bet, you son of a bitch?”

She’s stronger than I thought.

No, my victory is certain, but is she trying to make me back out by making me nervous with the big condition of becoming a slave?

Not a chance.

I’m not scared in this kind of situation, you little sister.

I can already see her living as a slave in the house soon.

“I’ll give you my entire salary for 10 years after I get a job. If you’re really gonna do it, record it… no, you’re too scared to do it, so there’s no need to record it.”

I can feel her glaring at me, grinding her teeth.

But what can I do? I’m sure to win, and if we’re going to do it, we have to do it properly.

How comfortable would it be to do nothing at home and have my sister do everything for me?

I give her a victorious smile.

“You fucking bastard, record it. This content is that if I get horny from being hit by oppa with my eyes covered, I swear to be oppa’s slave.

Instead, if I don’t get horny, oppa swears to give me all his salary for 10 years after getting a job. Do you swear, Kim. Seon. Ho.-ssi?”

She recorded it on my phone that was on the table,

and pushed the phone in front of me, waiting for my answer.

…So, this bitch is finally going to see this through.

I spat out into the phone without hesitation.

“I, Kim Seonho, agree to all of this and swear.”

After finishing the recording, my sister and I glared at each other.

Like wild animals in a battle of nerves, trying to devour each other,

we didn’t take our eyes off each other and glared, and got up from the table almost simultaneously.

“Why are you getting up?”

“I’m going to the bathroom.”

“Why are you getting up with me, you fucking bastard? See you later.”

“Shut up.”

When I moved to the bathroom first, she followed me, sending a sharp gaze from behind.

The men’s bathroom is structured to go up the stairs right next to the women’s bathroom.

I stopped for a moment and looked at my sister who was about to enter the bathroom.

My sister glared at me and raised her middle finger.

Yeah, she’s a bitch full of strange confidence that she won’t lose to me, so she can do that.

But I’m absolutely confident in this bet, and I can show you the proof now.

“Go to the bathroom and go home, I’m going somewhere else.”

I waved my hand at her appearance, which was dressed up to emphasize her figure.

Especially at the clothes that emphasized her butt and chest.

“Ah! You shibal bastard, where are you hitting!”

I slapped her butt with the palm of my hand and ran upstairs.

She must have already sensed defeat with just this.

I’ve never had a Majo-nyon that I’ve seduced with words in my life, even though she’s my own sister,

so I thought she would like the touch of my hand.

Even if she’s an animal, shouldn’t I have at least one weapon to beat my sister?

It would be easier to win and make her a slave and stop her from causing trouble,

so I smiled victoriously and headed to the bathroom.

–

“…Shii-bal Sae-aekki…No, how hard do you have to hit for your panties to get wet from one hit on the butt…? I’m screwed…”

My sister was sitting on the toilet in the bathroom, looking tearful as she looked at her panties that were wet with vaginal fluid.

Later, she told me that when I hit her before going to the bathroom,

she got wet right away.

Imagining that scene made me smile.

Winning in one go is something that all men would like.
