Between Sisters
“Something up?”
I opened the door and there stood Cha Ji-yeon.
She had just stepped out of the bath too; water glistened on her hair.
It looked like the order had been Mom first, little sister second, big sister last.
“…Se-yeon isn’t here. You didn’t come here either?”
Her tone was pure defiance, as if she wanted nothing to do with conversation.
“Probably not. Come in and check.”
“No.”
I flashed a grin, and Cha Ji-yeon actually took a step back.
“You’re worried about your sister, aren’t you?”
“Not really.”
If I told her to come in, she refused. If I blocked the doorway, she barged in anyway.
Cha Ji-yeon’s mischievous streak was still in full swing.
“Then why did you come? You couldn’t have come just to see me.”
“Don’t say things like that.”
“You came all the way to my room looking for Se-yeon? Maybe you really did come just to see me after all?”
“If you… tried anything weird with Se-yeon too…”
Cha Ji-yeon flushed with anger and tried to shout, but she forced her voice down.
“Anything weird? What kind of weird? This kind?”
“Ugh…”
I poked her chest with my finger.
She immediately slapped my hand away.
“Don’t. I’m not in the mood for that.”
“Really?”
I pinned her against the wall so she couldn’t escape.
“Who said your feelings matter? I’m the one who’s in the mood.”
I grabbed her chin and brought my lips close.
Cha Ji-yeon jerked her head away.
“You’re going to scream.”
“Go ahead. Let your mom hear. That way, tomorrow all of you will be on the street.”
“You coward…”
Cha Ji-yeon glared at me, teeth clenched.
Even that look looked cute to me.
“Mmmph!”
I forced my lips over hers.
Cha Ji-yeon stood there stiffly, giving no reaction at all.
Her fists were white-knuckled, trying to hold back humiliation.
“Open your mouth.”
It was boring just sucking on her lips while she stood rigid.
I forced her tightly closed lips to open.
But Cha Ji-yeon ignored me completely.
“If you don’t behave properly, I might touch Se-yeon too?”
“Hmph…”
Only then did Cha Ji-yeon relax her body.
“You should have done that sooner.”
She only listened when I added that one extra line.
I pressed my lips against hers again.
And pushed my tongue deep into her open mouth.
“Mmm. Suck.”
Cha Ji-yeon looked completely flustered, clearly unused to having her tongue kissed.
This time I bit the inside of her mouth like I had done to her little sister earlier.
I sucked on her lips and pulled her tongue out with my own, rubbing it against mine.
While I licked her entire mouth, I shoved my saliva deep into her.
Cha Ji-yeon frowned in displeasure.
“Hoo… hah… haah…”
But soon she gave up and stopped resisting.
I tasted her unwilling lips until I was satisfied and let her go.
“Hoo. How does it feel? You said you wanted to know what it felt like, right?”
That night when we first kissed.
A somewhat obscure foreign movie was playing on TV.
In the movie, a man and woman kissed. Naturally.
Like any Hollywood movie.
It wasn’t just a simple lip-to-lip kiss.
It was the kind where they devoured each other, sucking hungrily.
The scene that clearly hinted at sex was treated as completely normal.
“Why do foreigners do stuff like this? It’s disgusting.”
Cha Ji-yeon muttered in disbelief.
It probably also had something to do with watching the scene together and feeling embarrassed.
“It feels good, so of course they do it.”
“That’s good?”
“You said it’s disgusting. If it’s bad, why would they purposely do something dirty?”
Cha Ji-yeon had always picked fights with me like this, day after day.
So I had planned to answer neutrally and move on.
“…Want to try it sometime?”
For some reason, Cha Ji-yeon suggested it to me.
Of course I hadn’t accepted it right away.
I didn’t know her intentions.
So I used Future Sight to carefully consider every possibility.
If I accepted her proposal, surprisingly Cha Ji-yeon willingly offered her lips.
And from then on, there were no issues.
On the contrary, if I had refused, Cha Ji-yeon would have stayed in a bad mood for the rest of the time.
She wouldn’t even talk to me and would snap at the family for no reason.
At that time, the farthest future I could see was only half a day.
I couldn’t predict what would happen further in the future.
In the end, I accepted her proposal, kissed her, and three days later I was kicked out of the house.
“So how many men have passed through here since then?”
I toyed with the hand on her lips still covered in my spit and asked.
Cha Ji-yeon nervously slapped my arm away.
“You don’t know.”
“Yeah. I don’t know.”
“Mmm.”
This time I slipped my hand inside her clothes.
And groped toward my target.
“It grew a lot, huh?”
I squeezed her breasts through her shirt.
Bigger than her little sister’s by one handful, smaller than Mom’s by one.
It could be called big for her age.
The size was perfect, the shape was good, the feel was amazing.
Despite her dirty personality, this was still a face and body that screamed “beautiful girl.”
“If I keep touching you, will it grow more?”
“…Garbage.”
“Haha. Who’s sticking to this garbage?”
I sneered at her one last time before pulling my hand away.
I knew Mom was coming this way.
“Relax your face. If you don’t want to get caught by your mom.”
Even with my warning, Cha Ji-yeon’s glare stayed strong.
“Ji-yeon? Is Se-yeon over there?”
“…!”
Mom called from the other side.
Instead of answering, Cha Ji-yeon turned her back to me.
“Hmph.”
I sent her on her way without a word.
It was still the very first day. There would be plenty more chances.
It was fine that she was being defiant instead of obedient from the start. There was fun in training her.
Because Cha Ji-yeon was being defiant, the future where I would strip her naked and bully her was even more exciting.
I closed the door and stepped into the room.
Under the blanket on the bed, Se-yeon peeked out her face.
“Oppa? Did Nuna leave?”
Since she was wrapped in the blanket, she hadn’t heard our conversation from the doorway.
Even though I had just tormented her older sister, I told a straight face to Se-yeon.
“Hah. She left, but what do I do now?”
Not only Se-yeon’s sister but Mom too was looking for her.
The way she kept appearing and disappearing in the house was unnatural.
“Oppa, I’ll say I was hiding under the bed in your room. I was playing hide-and-seek.”
“…That’s a good idea.”
Not a kid.
If I said I was playing hide-and-seek in Oppa’s room, they’d think it was weird.
“If Nuna keeps asking, tell her you talked to me. She won’t be able to dig deeper.”
“Huh?”
Se-yeon tilted her head in confusion at my words.
“Oppa, what did you talk about with Nuna?”
“Nothing much. She asked if I did anything weird to you.”
“What kind of weird? This kind?”
With that, Se-yeon kissed my lips.
Puck.
Cute kid. She has no idea my lips are still covered in her sister’s spit.
“Yeah. I’m pretty untrustworthy too. I’d never do something like that to my cousin.”
“Hmph, you already did it.”
“Exactly.”
I gave Se-yeon’s small chest a quick squeeze and properly put her bra back on.
“Let’s go out soon. We’ll be suspected.”
But Se-yeon didn’t want to leave. She just stared at me.
“Oppa.”
“Why?”
“What are we now? What kind of relationship do we have?”
Relationship.
“Hmm, well… an evolving relationship, maybe?”
I didn’t want to define it with any specific term.
Honestly, Se-yeon was still my toy, but I couldn’t say that out loud.
“So it means it can develop more in the future? Right now we’re just cousins?”
“That’s up to you to decide.”
I dodged as much as possible.
It was never good to lock down positions.
“You could just tell Mom and Nuna honestly, right? About our relationship.”
Our relationship?
What kind of relationship?
Se-yeon probably thought it was something like boyfriend and girlfriend.
“Then I’ll be kicked out again? Just like ten years ago.”
“…Even though this is Oppa’s house?”
“If I don’t get kicked out, maybe it would be the opposite. All of you would go out together.”
Se-yeon hugged my stomach at my words.
“Why? Because Oppa and I are cousins?”
“Maybe.”
“That’s weird. I like Oppa, that’s why. If liking Oppa because we’re cousins is wrong. In foreign countries cousins can even marry.”
“Exactly. It is weird.”
I gently stroked the childlike Se-yeon.
“So we have to keep it secret forever…?”
“One day I might reveal it. When your family is free. And when Se-yeon can be completely independent from the family.”
“Yeah…”
Is Se-yeon imagining that day?
That day may never come, but even if it does, can I continue with you?
It was a truly naive dream.
“I’ll keep it secret until then. Because I don’t want to leave Oppa.”
It was admirable, but not trustworthy.
I felt like she would do something pointless right in front of her sister.
I didn’t even need Future Sight to see it clearly.
“Can you do it well? You have to be careful not to let anyone notice normally.”
“Don’t worry! I’m really good at acting!”
“Yeah. I believe you.”
Se-yeon stepped away from me.
And slowly put her clothes on.
“Oppa, then I’ll go. See you tomorrow.”
“Wait a second, Se-yeon. I have one last thing to say.”
“Eh? What?”
I stopped the Se-yeon who was trying to leave.
And leaned close to whisper in her ear.
“Before bed, while thinking about me, touch yourself.”
“Ma… st… ur… !?”
Se-yeon’s face turned bright red when she understood my words.
We had already done quite intimate things, but she still seemed to have no immunity to this kind of talk.
“Can you do it? This is today’s homework.”
“Ah…”
While saying that, I lightly touched between Se-yeon’s legs.
Se-yeon hesitated for a long time before answering.
“…Yeah. I’ll think about it…”
“I’ll check tomorrow.”
I couldn’t check if Se-yeon properly masturbated.
But by giving this command, I opened up new possibilities.
I already knew through Future Sight that tomorrow would bring even more fun to watch.
“Hoho.”
After Se-yeon left the room, I lay on the bed where her body heat still lingered.
Mom. And Mom’s two daughters, Cha Ji-yeon and Cha Se-yeon.
All three mothers were dancing smoothly on my palm.
The day when I would strip them naked and use them as slaves was not far off.
Thinking about that day, I laughed so hard it even felt unpleasant to my own ears.
