Something Has Changed
The Hye-mi noona I had seen in the student cafeteria earlier that day seemed exactly like her usual self. Her bright, energetic personality and the way she approached everyone without hesitation made me wonder if the awful dream I’d had last night was nothing more than a nightmare. At least until I saw her eyes and tongue.
What the hell was that? Had yesterday not been a dream after all? What exactly had that mask done to her?
I sat alone in the empty club room, tossing unanswerable questions at myself, when I suddenly sensed someone behind me. The sweet scent of shampoo—the same fragrance I had breathed in all night long. I didn’t even need to turn my head to know who was standing there.
“Hye-mi noona…!”
“......”
I pushed my chair back and stood, turning around. Right behind me was Hye-mi noona, the corners of her mouth lifted in a gentle smile. Yet her wide-open eyes weren’t smiling at all. They simply stared at me with hollow, empty pupils.
The way she stood there motionless, gazing at me, sent a chill racing down my spine. She said nothing. Even though she was clearly looking in my direction, it felt like she was staring through me into some deeper void. A vacant smile clung to her lips.
“...Noona, please say something…! Do you remember what happened yesterday…?”
“..........”
Unable to stand the anxiety any longer, I pressed her urgently, but Hye-mi noona remained completely silent. She simply stood there watching me, exactly like she had last night after putting on the mask and freezing in place.
This was too strange. When I had seen her in the cafeteria at lunch, she had been talking and laughing normally. She had carried on conversations with other people and gone about her day as if nothing was wrong. But the person standing in front of me now—was this even the real Hye-mi noona?
An indescribable dread washed over me. I took a step back and pulled the ‘mask’ out of my bag. It was a bizarre object with no special patterns or decorations, just painted plain white. The reverse side was densely covered in strange characters I had never seen before.
Hye-mi noona had put this mask on and changed into… this.
I looked back and forth between the mask and noona, who continued to stand there with that dry smile even after such a long silence. Had this been the expression she made while wearing it…?
I recalled the events of last night, which had happened less than twenty-four hours ago. It had started as a joke from Hye-mi noona, but the moment she put on the mask, something had gone terribly wrong. She had moved like a robot, obeying only my commands, while I had surrendered to my desires and crossed every line. And then… the jade-colored change in her mucous membranes and the tentacles writhing inside her pussy.
Just thinking about it made heat rise to my face. With the person herself standing right in front of me, what the hell was I thinking about…? Yet the something squirming in my chest refused to agree with my reason.
Her short denim shorts revealed the contours of her legs just as clearly as yesterday’s leggings had. A tight T-shirt and a thin cardigan. I kept picturing the pure white skin beneath those clothes—the skin I had seen, touched, and enjoyed yesterday.
I didn’t understand why I was acting this way. I knew Hye-mi noona had a precious lover she cherished. I knew full well that what I had done would hurt both her and the man she loved. But I couldn’t stop.
Even though I had drawn a rational line I should never cross, the moment I came to my senses I realized I had already stepped over it. Everything had started changing after I picked up that mask—after I read the characters engraved on it.
Even as I thought this, my mouth was moving on its own.
“...Noona, open your mouth and stick out your tongue.”
She wasn’t wearing the mask, but if she was still in the same state as yesterday…
“........”
The moment I gave the ‘command,’ Hye-mi noona’s hollow eyes flashed with jade light. Her red lips parted with a wet sound, and she extended a tongue the same color as her irises.
Her tongue was about one and a half times longer than a normal person’s, and an unnaturally sticky saliva dripped from the tip, stretching into thin strands. But what caught my eye most of all was the emerald hue that had completely stained her tongue and the mucous membranes inside her mouth. No matter how many of those cheap candies I used to buy at the stationery store as a kid I ate, they could never produce a color like this.
It was a sight that defied common sense and logic, yet absurdly enough, my pants were already straining to the point of bursting.
I slowly raised my hand and placed a finger on her outstretched tongue.
“.......♡”
Slurp. A soft, slippery texture. Small, rough bumps brushed against my skin. Then her elongated tongue coiled between my fingers as if trying to lick away the dirt and sweat from my hand.
Under normal circumstances I would have yanked my hand away in horror, but I remained eerily calm—so calm it frightened me. I stared into her eyes as she licked my fingers without any change in her expression, then withdrew my hand. It was soaked with so much saliva that the entire thing glistened. The fluid was so impossibly sticky that it refused to wipe off easily.
“.......”
I took a moment to admire her hot, narrow throat. This hole would probably feel incredible too. I want to feel that same pleasure from yesterday again. The thoughts occupying one corner of my mind completely took over my reasoning, and my hand drifted lower toward my zipper.
“Noona, just like that—”
I was about to cross the line once more when—
Creak.
“Oh, Wooju oppa? What are you doing here? And Hye-mi unnie?”
With the sudden sound of the door, a girl entered the club room. She wore glasses and had the neat, diligent appearance of a model student—Ko Yunsol from the reading discussion club. My junior in the same club stood at the doorway, looking back and forth between me and Hye-mi noona.
“...What are you two doing?”
“Ah, no… it’s just…”
I carefully hid my crotch and tried to come up with an excuse when—
“Ahaha, I got completely drunk yesterday and Wooju helped me out. I was just thanking him~ What about you, Yunsol? I thought all the other reading club members already went home?”
“Ah, yes. I left behind some materials I need for this week’s debate, so I came to pick them up.”
The noona who had been standing there like a statue suddenly spoke naturally, changing the subject and chatting with Yunsol. I was a little surprised but tried not to show it, only letting my eyes dart around.
I still had no idea what was going on.
“Then you two can keep talking. I’ll be done soon…”
“Okay, good luck, Yunsol~”
Hye-mi noona flashed a bright smile as Yunsol sat down in front of the computer in the corner of the room. Then she turned back to me.
“...Ugh…!”
Her eyes were hollow again—completely different from when she had been speaking with Yunsol. I watched her carefully so Yunsol wouldn’t notice. The girl had already put in her earphones and was typing away on the keyboard, seemingly paying us no attention.
“........”
I quietly pulled a chair over and sat down, then whispered into the ear of the noona who stood rigidly in place.
“Noona, suck it.”
“.........”
Still seated, I quietly unzipped my pants and pulled out my already rock-hard cock. Without answering, Hye-mi noona slipped under the desk, opened her mouth wide like a dripping pussy, and extended her writhing tongue.
She gave the underside of my shaft a slow, rough lick with her hot, bumpy tongue as if tasting it, then showed me something I could scarcely believe even though I was seeing it with my own eyes.
“.....Ahh…♡”
From deep in her throat she pulled out two tentacles covered in dense bumps. They spread wide as if welcoming my cock, and soon her tongue and the two tentacles wrapped tightly around my length.
“Ugh?!”
“Slurp, chu, haa, jubu, chup♡”
Hye-mi noona took my cock—completely hidden by the tentacles—into her mouth, stretching her lips obscenely as she sucked. The noona I had always thought of as kind to everyone, a good friend, a good person, was now shamelessly latched onto my dick.
Only now was I certain. This was no longer the Hye-mi noona I knew. She had been transformed into something else.
Even though her face was a complete mess, her wide eyes never left mine. They seemed to ask, ‘Does it feel good? If you need anything, just tell me.’
The rough tongue, the bumpy protrusions on the tentacles, the sticky lotion of her saliva. The frantic movements trying to milk my cum from my balls just like yesterday forced me to bury my face in the desk to stifle my moans.
I carefully lifted my head to glance at Yunsol, but she still didn’t seem to have noticed.
“Slurp♡ Sluurp, chup♡”
The greedy, wet sounds filled the entire club room. The thrill that Yunsol might hear us at any moment, combined with noona’s quiet, auditory service, pushed me past my limit faster than yesterday.
“....Ugh…!!”
“Gulp! Gulp! Gulp!♡”
Without warning I grabbed her head and slammed my glans into her esophagus, beginning to cum. Thick semen surged through my urethra, filling her mouth to the point that it overflowed and flowed back out through her nose, but Hye-mi noona didn’t change her expression in the slightest. She simply drank it down as if she had been waiting for it.
Still slumped over the desk, I quietly finished ejaculating and finally pulled my still-rigid cock from her throat.
“Haa, haa…!”
…It was incredible. I had thought nothing could feel better than cumming inside her pussy yesterday, but that record had been shattered in less than a day. I savored the addictive afterglow of that overwhelming pleasure as I looked down at Hye-mi noona beneath the desk.
“...Gulp…♡”
She swallowed the last drops of semen remaining in her mouth, and her eyes glowed even brighter. Then, smiling more radiantly than ever, she wiped the stray hairs from the corner of her mouth and spoke.
“...It was delicious. Thank you, Wooju…♡”
Finally, the Hye-mi noona who had been standing there like an emotionless robot had spoken. But although her smile and tone belonged to the noona I knew, something about them was unmistakably different.
“Noona, what the hell…”
“Shh. Yunsol might hear…♡ First I should do what I need to do…”
With those words, she pulled out the ‘white mask’—I had no idea when she had picked it up—from her pocket.
“Bwehh…♡”
She opened her mouth slightly and spat out a thick jade-colored fluid along with her tongue onto the back of the mask. The liquid that pooled on the reverse side instantly soaked into the mask, and the strange characters on it began to glow eerily.
Hye-mi noona smiled sweetly as she wiped her mouth, then emerged from under the desk holding the mask.
“Yunsol, could you take a look at this for me?”
“Oh, yes? What is it, unnie?”
She walked over to Yunsol, who was sitting energetically in front of the computer.
“Wait, noona, hold on…!”
I realized what she was about to do, but it was already too late.
“I can’t figure out what these characters say~ Do you know what they mean, Yunsol?”
“No, I don’t… But somehow this is…”
Hye-mi noona had already shown Yunsol the characters written on the back of the mask. The junior frowned slightly as she examined the text, but her expression quickly went slack. Before I knew it, she had taken the mask from Hye-mi noona’s hands.
“...For some reason my head feels all black inside…”
“Yunsol. Put it on.”
“............Yes.”
