Was the Dream a Premonition?
For the first time in my twenty years of life, I tried studying ahead. Math, of all things.
Simply to forget the filthy dream starring Unnie Hajin.
The equations in the book tormented me like they were wringing my brain dry, but by the next morning I had managed to claw my way back to normal.
"Ah, my head."
A faint headache still lingered, as if the aftershock of all that math prep refused to leave.
Studying with Unnie had actually been fun enough that I'd given it a shot, but I wasn't at the stage where solo study felt enjoyable yet.
People always say you shouldn't do things you don't normally do.
But I hadn't had a choice.
Aside from math prep, there had been no other way to drive that dream out of my head.
"Hello, Mother."
"Hello, Hajin. You're dressed so flashy today."
"After class today we're grabbing lunch and then going out to play with Jaehee."
"I see. It looks wonderful on you, Hajin."
"Really? Thank you, Mother."
The sound of the door lock opening was followed by Mom and Unnie Hajin's conversation drifting through the door.
The part about her dressing flashy kept circling in my ears.
Yesterday she had given off the vibe of a teacher coming to tutor a student, mixed with something like a club VIP.
What kind of look was she going for today?
"Jaehee, hi."
"Whoa."
The moment I saw Unnie step through the door, a short gasp of admiration slipped out first.
A black halter top under a denim jacket—anyone could tell this wasn't an outfit for teaching a student.
This was pure going-out-to-play attire.
And with sunglasses perched on top of her head on top of that, I couldn't even begin to guess how thoroughly she planned to play with me after lunch.
I was first startled by how much lighter the outfit was than I'd imagined, then startled again by the atmosphere and beauty that called an idol photoshoot to mind.
Honestly, Unnie Hajin's face carried the whole look from start to finish.
"Unnie, your outfit today is insane."
"We have to play, right? You can't wear a shirt and skirt to go out and have fun."
"What are we going to do?"
"I'll tell you after we finish studying. If I tell you now you won't be able to concentrate."
If I say that just this outfit alone is already enough to kill my concentration, that would be bad, right?
"What did you do after studying with Unnie yesterday?"
"Huh? What do you mean, what did I do?"
"I'm curious about Jaehee's daily life. I want to know."
"I ate lunch, took a nap, worked out, and did a little math prep."
"You did math prep? Studying with Unnie made it fun, huh! Really well done, our Jaehee."
The news of my prep made Unnie clap her hands in delight; she even stroked my head with a look of proud affection.
It had been so long since anyone had ruffled my hair like that that I felt oddly embarrassed.
"Does Jaehee dream a lot when she sleeps?"
The question Unnie tossed out so casually was completely ordinary. Yet I felt my breath catch in my throat.
Because everything I had desperately scrubbed from my mind began crawling back up, one slimy piece at a time.
The unfamiliar scent that had thickly filled my room, Unnie Hajin's hot, lewd breath tickling my ear, the maddening stickiness and heat I'd felt between her thighs pressed against mine—
Every single detail came roaring back in less than a second.
I felt heat rush straight to my face.
My ears had to be burning bright red all the way to the tips.
"Uh, well… sometimes I do, sometimes I don't."
My voice suddenly trembled enough that anyone watching would have found it strange.
At the same time my gaze wandered the air, not knowing where to land, and I nearly locked eyes with Unnie staring straight at me—I flinched hard.
Is it just my imagination that her gaze suddenly feels lewd and sticky?
"What's wrong, Jaehee?"

Of course Unnie found my weird behavior suspicious.
She rested her chin on her hand atop the desk and gave a light smile, as if she had already read every single thing inside my head and was only asking for confirmation.
"Ah, nothing… it's nothing. Let's start studying already, Unnie."
What I needed right now was math.
I flipped the pages of the math book in front of me like I was about to rip them out on the spot, and Unnie clapped again, praising how nice it was to see such passion.
"Our Jaehee wanted to study math with Unnie that badly, huh?"
Naturally she had no way of knowing it was so I could forget the dirty dream starring her even one second sooner.
Before long Unnie smiled sweetly and scooted right up beside me.
"Good. Unnie will teach you how to properly enjoy math."
At those words my heart seemed to drop, then immediately began pounding as if it would burst.
"Jaehee, Unnie will teach you how to properly have sex."
It made me vividly recall the line I'd heard right before waking from the dream.
"I'm going crazy…"
A small, pained sound slipped out before I could stop it. The moment that voice hit my own ears, my face flushed so hard it felt ready to explode and my mind went completely blank.
Until a moment ago Unnie Hajin had simply been a pretty unnie who dressed well; now her presence suddenly pressed in far too heavily.
The tiny rise and fall of her shoulders with every breath, the white skin peeking dangerously between the straps of the halter top, the same sweet yet heavy perfume scent I'd smelled yesterday rolling off her body—
Every one of those things scraped mercilessly across my nerves.
"Jaehee's face is red. Do you have a fever?"
"I must be hot. Let's start studying, Unnie."
"Okay, sure."
I believed that once we started math my head would settle again. But things unfolded differently from yesterday.
"Jaehee, that's wrong. You can't group it and calculate like that."
"Ah, right."
"What did Unnie say yesterday?"
"Uh, that was…"
"Find the chunk and give it the name u, remember?"
I completely forgot concepts I had understood instantly from her explanations the day before, so my approach to every problem was wrong, and even when she explained important points again I let them slide right past.
At first Unnie cut me some slack, thinking I just wasn't used to math yet.
—Squelch!
"Unnie?"
"Jaehee, why can't you concentrate at all? Completely different from yesterday."
When the same thing kept happening, she pressed the tip of her pen into my cheek and stared at me with clear dissatisfaction.
"Are you really sick somewhere? Your face keeps staying red and I'm getting worried."
"I'm sorry, Unnie."
"Unnie doesn't want an apology. I want a reason. If I don't know the reason I can't adjust for Jaehee."
"That's…"
Of course I couldn't tell her the real reason. I needed to invent some decent excuse, but my entire head was stuffed full of the dirty dream starring Unnie.
"Maybe Unnie shouldn't have mentioned going out to play yesterday. Feels like that's why you can't focus."
"That's… not it."
"Or did someone start occupying your thoughts overnight?"

Unnie stopped poking my cheek and raised both arms in a stretch.
When she arched her arms back behind her head, the side of the black halter top gaped open, revealing the soft curve that ran from her underarm in one smooth line.
My gaze followed that curve and stopped dead on the side of her breast, so full it looked ready to burst free.
The white skin peeking out so dangerously, and that silhouette—they looked far too much like the soft fullness that had completely filled my palm in yesterday's dream.
In the dream Unnie's breasts had looked incredibly soft. Soft enough that I had lost all reason and lunged for them, even though I barely liked girls.
I shouldn't think about it any further, yet the image of her nipples and areolas hardened and jutting out rose up again, overlapping perfectly with the chest right in front of me.
I can't keep doing this. If I do, even just being near Unnie is going to get hard.
"Ah, no…"
The answer to whether someone was on my mind rose all the way to my throat, but I never managed to spit it out.
"That's enough studying for today."
"Huh? Already?"
"In this state we're just wasting time. It'll be hard on Jaehee too. Instead, tomorrow we do two hours."
"Yes, Unnie. I'm really sorry."
"If this happens again Unnie will scold you. When Unnie gets mad I'm actually scary."
I nodded, then sucked on the drink Mom had left out earlier through the straw.
I only realized I'd been chewing the straw to pieces because Unnie kept occupying my thoughts when the drink stopped coming into my mouth.
"Or maybe it's because Unnie is too pretty."
"I think that's it."
"Oh my, really?"
I had to explain the difference from yesterday somehow, but my mouth wouldn't open properly, so I just answered with whatever came to mind.
"Then do I have to go bare-faced every time I meet Jaehee? Even so, I want to look pretty in front of Jaehee."
"Why?"
"Because I like Jaehee. You're handsome."
Is it because of that dream yesterday?
The words "I like you" hit me a little differently now.
"Unnie, if this is out of line I'm really sorry, but can I ask just one thing?"
"What are you going to ask that makes you so careful?"
"Unnie, do you like girls?"
The Unnie I'd seen yesterday had been a friendly, kind older sister type.
But after watching her press her body against mine so stickily and lewdly in the dream, the thought that she might be a lesbian had crossed my mind.
"Jaehee, does Unnie's face say 'starving lesbian who desperately needs girls' or something?"
"No."
"Then is Jaehee a lesbian too?"
"No."
"You're not?"
Why is she surprised that I said no?
"Pfft!"
She laughed like it had all been a joke, then rested her chin on her hand again and tapped her cheek with a finger, putting on a fairly serious expression. She looked like she was thinking something over deeply.
"Then how am I supposed to know? There's no way to tell."
That reaction was basically the same as answering my question with a yes.
"Of course, I haven't met a girl in quite a while so I am pretty starved."
I think I just heard something I wasn't supposed to hear.
"Unnie, if that made you uncomfortable I'm sorry."
"It's fine. I am a lesbian, after all."
"Then when you said you like me, does that mean…"
"I'm trying to seduce Jaehee."
"Why? This is only the second time we've met, and I'm not a lesbian."
"If I say it was love at first sight, will you believe me?"
I had even less of a clue what Unnie was thinking now.
I wasn't pretty or charming enough for anyone to fall for me at first sight. So why on earth?
"Me?"
"Yeah. Curious about the reason?"
"Yes, of course I am."
"You're handsome."
The situation was so familiar that I just stared, and instead Unnie tilted her head in confusion.
"You're not surprised?"
"I've heard that reason a lot."
"From who?"
"From elementary school all the way up to two days ago."
"So you just go around seducing every girl?"
"I've never seduced anyone."
"How many confessions have you gotten? Be honest."
I stared into space for a moment, trying to count how many times girls had confessed to me so far, then gave up because there were too many.
"A fair number."
"Player."
"Huh? I've never even dated anyone."
That short, narrow-eyed scolding suddenly made me feel like the bad guy.
"What a sinful woman. So if Unnie seduces you and takes you away, that means Unnie beats out all those other girls, right?"
"Is that… how it works?"
Somehow it didn't land as a light joke.
The will to seduce me no matter what was burning hot and bright.
"Still, there's something different."
"What?"
"You're the first person who's ever openly said they're going to seduce me."
"…Sounds like you're telling me to try it if I can."
"Um… that wasn't what I meant."
"Heh!"
She let out a small laugh and stood up from the chair.
In that instant my vision seemed to sway, and the next thing I knew I was lying on the bed.
"Huh?"
I hadn't even managed to make a sound of falling before I found myself on top of the mattress; only then did the question form, and in that gap Unnie climbed over me.
With movements that were somehow sticky and lewd.
"Jaehee."
"Uh, Unnie?"
She even slipped one leg between mine as she closed the distance, and before I knew it we were face to face.
Just as I started to panic at the feeling of our chests pressing slowly together, both of her hands gently stroked my stomach and my head.

"Our Jaehee has abs too, huh?"
"I… worked out hard, so…?"
While continuing those blatantly erotic caresses, she whispered quietly.
"If you keep this up, Unnie might just devour you whole."
