Panties... Completely Soaked
Something had felt off. I'd known it.
The Hero's companions had all gotten drunk on my saliva too. Even granting that the bastard had taken my head and I'd lost most of my magic, it still didn't add up. There was no way she could swallow my saliva—laden thick with my power—twice over and not be seized by the urge to crave me.
All this time, whenever I practiced basketball, she had been barely slaking that hunger with the sweat-soaked clothes I'd left in my locker. The faint smear of Senior Sohee's juices on the locker door was the proof. Thin as it was, that sharp, tangy scent she gave off when she went into heat clung there without any mistake.
I didn't think Senior Sohee had it in her.
I studied the faint stain. Judging by how dry it was, it had been left last night. The image of her slipping in when the department room was empty, burying her face in my clothes and touching herself, pulled a dry chuckle out of me.
She's a complete bitch in heat.
Only then did the thrill that had been held back come flooding through me. I couldn't pretend I hadn't been a little anxious—that maybe my magic simply didn't take on Senior Sohee—and that unease had kept me from properly tasting the conquest. But after confirming the nectar that had spilled from her lower lips, I was certain. Senior Sohee was being dyed in my colors, without a single hitch. And like water bursting from a broken dam, dopamine poured through my skull.
So she's been stealing my scent behind my back this whole time?
A prick of indignation came with it. How dare she take in my smell without this body's permission? As a former Demon King, it was something I could not tolerate. Until I allowed it, no female was permitted to claim so much as a scrap of my clothing as she pleased. Senior Sohee needed to be taught that rule of mine, thoroughly.
The time to begin her education will come soon enough.
It was right around the corner now. The day Senior Sohee would be reduced completely to my thrall. When that day came, I would strip away the fragile mask hiding her instincts and let her feel, without limit, the happiness of being a female.
Classes were over at the Business Administration College Main Building. Past six, students and staff were hard to find. Unless something came up, there was no reason to linger on campus.
Haa...
Of course, something had come up for Sohee, which was why she was still in the main building—in the Business Administration Department Room. She had gone carefully through the hallway, the lecture halls, even the bathrooms, confirming that no one was around, and only then slipped quietly inside.
Silence settled over the room. Right now, she was the only person in this building, on this floor. She had already checked, thoroughly.
...Good. Nobody's here.
Certain of that, Sohee strode forward—toward the locker with the name Kang Minsu written on it.
Clunk—
As if it were already second nature, she opened the locker door. Inside, just as she had hoped, was the shirt Minsu had worn during today's basketball practice.
Haa... I heard he ran longer than usual today.
Ever since the day she had first tasted the clothes in Minsu's locker, she had stayed behind alone every evening, late, to raid it. The shirt inside. His scent soaked into that shirt. She had fallen into the addictiveness of that smell and could not pull herself out.
...Haa... How did I end up like this.
Even Sohee herself didn't know. On the first day she realized Minsu's scent was coming from the locker, she hadn't touched a thing. She had just brought her face close, taken a brief sniff, and that had been enough. But on the second day she ended up opening the door and sticking her head inside to breathe it in. On the third, she took his clothes in her hands and pressed them to her own nose. And on the fourth, she carried his shirt to a corner of the department room, crouched down, and buried her face in it. Even that wasn't enough. She undid the button of the jeans she was wearing, and soon her hand found the sticky place inside her panties.
In the end, Sohee had chased pleasure to her heart's content in the department room—an open, public space—without anyone knowing, feasting on the scent of a man named Kang Minsu. All of it had happened in just four days. In that short span, she had completely crossed the line. They had been the most precarious, passionate, and cathartic three days of her twenty-three years.
Sohee had never felt this way in her life. Under the pressure of overbearing parents, under the image she had to project to everyone around her, another self inside her had been suppressed and crushed—and it was as if that self had finally snapped awake. She didn't entirely dislike the feeling.
Today... it'll be even stronger, right...?
Recalling those past three days, Sohee picked up Minsu's shirt. She walked to the corner where she had secretly done the deed yesterday and crouched down.
"Hnnngh...!"
She buried her nose in his shirt at once and quickly undid her pants button, dragging the zipper down. Into her pale pink panties with their little ribbon, she slipped her hand as if it were the most natural thing in the world.
Squelch—
"Haaah...! Haah...!"
Her sex trembled faintly at the sudden arrival of her fingers. But those fingers, as if they belonged to someone else, paid no mind and began rubbing at the still-quivering entrance of her vagina.
Squelch— squelch—! squelch—!
"Hnnnngh... hahk...! Huuhk...!"
Her moans grew rougher. In time with them, the sound of her fingers tormenting her slit grew louder too. Just as she had expected, today's clothes from Minsu held a more intense scent than before. That scent met the venom spreading through her and set off fireworks of pleasure inside her body.
"Ugh!... uungh..! knngh..! nngh...!"
Now it wasn't only the slit between her legs. Her thighs, her lower belly, her chest and shoulders began to tremble. It was the touch of a demonic beast, forcibly waking the sexual senses that had lain dormant in her. The seed of a succubus had taken deep root inside Sohee, and the sprout grown from that seed had flourished until it finally bound her reason tight and held it captive.
This place, just a few hours ago, had been a department room where countless classmates came and went. The fact that she was doing something no one should see, in a public space anyone could walk into, churned through her mind. Guilt had long since been used as fertilizer for her pleasure. If this kept up, she might end up doing something even more dangerous than this—Sohee thought it, and then—
"Haaahk—!!!"
Fwoosh—!
In the end, Sohee let go completely, gushing right where she sat. Over the past three days she had crossed the line, but she had never gone all the way. Whether it was because Minsu's scent was especially strong today, she had finally gone all the way.

Ha... haa... This can't be happening.
Sohee's heart hammered. Only then could she see what she had done—the situation she was in. In the department's shared lounge, with a junior guy's clothes pulled over her face, sitting in a corner, she had wet herself.
Sohee... have you actually lost your mind...
She scolded herself. Even if she was going off the rails, there had to be a limit. Shooting out a stream like she did at home. With a face gone bright red, she rummaged through her bag and pulled out tissues, wet wipes, and a spare pair of panties—packed on the off chance that something like this might happen.
Hurry... clean up and go home.
Sohee didn't want to stay in the department room a second longer. It was the shame that came flooding in like a tide after she'd reached climax. She wiped the floor diligently. Fortunately, it didn't seem to have splashed anywhere else.
Panties... completely soaked.
Not just her panties—her pants were wet too. Because they were jeans, the damp patch showed.
At least... change the panties.
Sohee took off her jeans and peeled off the soaked panties as well. After changing into the spare pair, she neatly folded the wet ones and tucked them into her bag.
The pants... can't be helped.
She had no spare, so she had no choice but to put the wet jeans back on as they were. The one silver lining was that the damp area wasn't that large. If she pulled her top down, she could just about cover it.
Having cleaned the scene thoroughly, Sohee looked around carefully this way and that, like a criminal surveying the site of the crime.
Nothing left? All cleaned up? If people come in tomorrow morning... they won't know anything, right?
A perfect crime. Sohee let out a sigh, hoping that today's events would remain her secret for the rest of her life. She must not get caught by anyone. A girl known for never even properly holding a guy's hand, let alone dating—caught masturbating alone in the department room after classes were over?
That's death... social death... uwaaaagh...
Sohee sat in a chair on one side of the department room, clutched her head with both hands, and slumped over the desk. She had no idea how she had ended up like this. Had it simply been time for something to burst? Did everyone else also live holding back the same kind of desire?
Those questions were blooming in her mind when—
Beep-beep-beep-beep—
Someone punched in the passcode on the department room door lock.
