The Wager
“Damn it, there isn’t a single spot on me that doesn’t hurt.”
“Still, isn’t it a relief that it stopped at this much?”
My joints still throbbed as if they remembered the damage, and I couldn’t get used to the newly grown legs and hands. I had rested, but the injury had been severe; the scratches and scrapes on my face hadn’t fully regenerated. I came to campus covered in ointment and bandages. The worst wounds had healed, yet for some reason they still ached.
“It hurts…”
“Stop whining.”
I had muttered it under my breath, but Chae-yun heard me. She patted my back from beside me and spoke louder. “Come straight home after class today.”
“…It’s not even your house.”
“Doesn’t matter. We need to look into that thing you caught yesterday. Seo-hee said she’d keep an eye on it for now.”
“…”
The one responsible for leaving my body in this battered state was currently fast asleep in my studio apartment alongside Seo-hee. Whether it was the strength of Seo-hee’s paralytic venom or not, unlike me—who had slept the entire previous day to recover—the creature still hadn’t opened its eyes. A poison capable of knocking out even a monster like that. Anyway, she had confidently declared she would watch over it while we were at school, so I left it in her care. I was uneasy, but there was nothing else to do. She would handle it.
“…Then, oppa, you should head in now.”
“Yeah. Thanks.”
Lost in recollection of yesterday’s events, I had already reached my lecture hall. Normally I would have walked Chae-yun to her building, but after I had nearly died, she insisted on escorting me today. I let her. Being fussed over like an invalid wasn’t entirely unpleasant.
“I’m going.”
“Text me when you’re done.”
I turned and waved casually. Chae-yun kept waving back with a worried expression, watching until I entered the classroom. I nodded to show I was really fine. Only then did she turn away. I grasped the doorknob and stepped inside.
“…was it?”
“What the hell.”
The classroom, usually quiet, was unusually noisy. Students chattered without noticing anyone had entered. Had I come to the wrong room? I leaned backward like I was doing the limbo, poking my head out the door to double-check the room number.
“…It’s the right one.”
“Professor Han Hui-ju canceled today for personal reasons.”
The girl who approached my ridiculous posture and explained the cause of the uproar was Seo-rin, the class representative.
“…Canceled?”
“Everyone here only found out after they arrived. They couldn’t reach her.”
Seo-rin reported in her usual cold, emotionless tone. The noise came from students celebrating the sudden holiday and others grumbling about waking up early for nothing. But complete loss of contact? …Ah, shit. I had forgotten.
It seemed the professor’s disappearance was my fault. I had forgotten after dealing with that woman yesterday—the special aphrodisiac Seo-hee had prepared. Even diluted, it was potent enough to send a person into heat instantly, and the only antidote was my semen. I had asked for something decisive, but I never imagined this outcome.
I broke into a cold sweat as I listened to my classmates’ cacophony of delight and irritation echoing from inside the room.
“Hey, where does Professor Hui-ju live again?”
To resolve the situation, I asked Seo-rin— who was close with the faculty—for the professor’s address.
“…Is anyone home?”
Less than thirty minutes later, I stood in front of the door to Professor Han Hui-ju’s officetel. It seemed rather large for a woman living alone. I kept repeating the same words.
“Is anyone there? Professor, it’s Im Chan-woo.”
No sound came from beyond the door even after I gave my name. It couldn’t be. The worst possibilities flashed through my mind, sending a chill down my spine. No matter what, she couldn’t be dead. The drug was strong but diluted, and she had been lucid for about five minutes after taking it. Probably…
“…Excuse me.”
I decided I needed to check. I forced the doorknob until it broke and stepped inside. The entryway was dark. Even though it was morning, the entire apartment was pitch black, as if every curtain had been drawn.
“Mm?”
The moment I passed the entryway, I felt it—an instinctive unease. It was the smell. How to describe it… a strange blend of a woman’s fresh shampoo and the damp-cloth scent that fills the air on rainy days. Neither pleasant nor foul, yet it saturated the entire apartment.
Pushing through that thick odor, I moved deeper into the apartment with the caution of someone exploring a haunted house. The further I went, the stronger the scent became. Then I began to hear voices.
“…Ugh…!!♡ Mmm!!…♡”
I turned toward the source. At the end of the hallway stood a tightly closed white door. Even through it, the woman’s moans pierced the barrier and echoed faintly into the living room.
“Professor?”
“…Haa…♡! Uup..!!♡”
I knew without doubt that it was the professor beyond the door, but she gave no answer—only those muffled, hungry moans continued.
“Professor, I’m coming in.”
I had been polite enough. I half-expected to break this door too, but fortunately the handle turned smoothly. The moment the barrier vanished, the moans, the moisture, and the obscene heat wrapped around me with vivid intensity.
“….”
“Aaaaaah!!♡ Haup…♡!!”
The professor’s condition was far worse than I had imagined. A liquid—whether sweat or saliva, I couldn’t tell—had soaked the entire bed. Her hair was a tangled mess, and she wore only a few pieces of sophisticated lingerie. In one hand she violently thrust a dildo into her pussy; another was stuffed in her mouth as she rolled her tongue around it, pushing it deep into her throat again and again. She hadn’t noticed me at all, lost completely in a masturbation frenzy.
Nearly twenty-four hours had passed since she took the aphrodisiac and was left alone. She had been pleasuring herself the entire time, yet she still couldn’t break free from the endless cycle of pleasure.
“Where the hell did those come from…”
My bag sat in one corner of the room. That’s right—I had left it in her office yesterday in my rush. The very bag that contained the adult toys. This entire disaster was my fault from start to finish.
As I stood there wondering how to clean up this mess, the professor finally noticed me. She turned her head, eyes landing on my face.
“…Man…♡?”
“Professor?”
Before I could say another word, she lunged at me, wrapping her arms around my body and burying her face in my chest, inhaling deeply.
“…!!!!♡♡”
Violent tremors ran through her. Her legs shook as she tried to stay upright, but she collapsed on the spot, clear fluid gushing from her exposed pussy. Had she come just from my scent?
“…Haa…♡…”
Even while drowning in the aftershocks of climax, her hand still clutched my collar. She yanked my pants down, exposing my hardened cock right before her eyes. Like a puppy staring at a treat, she stuck out her tongue, breathing raggedly, eyes locked on my length. The disgust she once showed me was completely gone.
“Wait, Professor. Are you still yourself right now?”
The suggestion I had planted in her—and in the other her living inside her head. The more pleasure she felt, the more her original self would fade as the parasite took root. I asked to see how deeply it had already consumed her.
“..Cock..♡! Cock…♡ Please give me…♡”
Damn. She clearly wasn’t in any state to give a proper answer. In that case…
I pressed my index finger to her forehead once more. A faint blue glow swirled at the tip. The flushed, lust-drunk expression on Professor Han Hui-ju’s face drained away, replaced by blank emptiness. As she drooled with a vacant stare, I planted a new suggestion to help her.
“…That should do it.”
The moment I pulled my finger away, awareness returned to her eyes. Her body, however, remained in full heat. Enduring the desires and pleasure that had built up over twenty-four hours would not be easy.
“…This is…♡ Chan-woo…?!♡ You again…!!♡”
“Don’t get too angry, Professor. I saved you when you were about to die.”
“What are you…♡?”
“You don’t even realize what you’ve been doing, do you? Ever since I left yesterday, you’ve been locked in here masturbating nonstop. The more you feel pleasure, the more you disappear.”
Only then did memory flood back. Her face turned deathly pale.
“Ah… Aaaah…! That can’t be…!!”
“I tried to save you, but it looks like I was a little late.”
“What the hell…!!”
“Calm down and look at me. Do you still hate me like before?”
“Of course I… Huh…?”
First confusion, then realization, then pure horror washed over her face. I stroked her cheek with my hand.
“I-I don’t hate it…♡ No, that’s not what I meant…!!”
The moment she felt my touch, her expression turned like that of a lovestruck teenage girl. She became visibly confused by her own emotions.
“See? You’re right on the edge of disappearing, Professor. So let’s settle this with a single bet.”
“What kind of…?”
“The only thing that can fix your current state is taking my cum inside you. If you can endure until I finish once, you win. If you lose… then you won’t be yourself anymore.”
“…You’re serious?”
“This time I’ll keep my word.”
I took my cock in hand and rubbed it against her soft cheek. She swallowed once, eyes fixed on it, then spoke in a voice full of resolve.
“Fine.”
