140. Midterm Bliss at Hasun's House – Clear Mind from Sister Donburi and the Eccentric Scientist
Studying for midterms at Hasun Park's house, complete with a bonus sister donburi session, cleared my mind and made everything click even better. 'Though honestly, I think I spent more time fucking than studying.' Thanks to Hasun, I actually got some real work done, so I scraped through the midterms without a hitch. Not great grades by any stretch, but no fails either. My homeroom teacher did chew me out a bit since my scores had dropped...
Anyway, today was supposed to be a celebration with Mom and Hyunji Kim, but after hearing what those lewd sisters had to say, I changed my plans.
"This the place?"
I attend a vocational high school right in front of a university, so I rarely have reason to come here. But today, I made a special trip for one specific check. Tense because this might be where the person I've been hunting for hangs out, I stepped inside the university grounds.
A few days ago, during our final pre-midterm cram session at Hasun's house, our chat turned to her "weird" friend. This woman five years older than me had been tinkering with strange gadgets since she was a kid. Invention alone wouldn't raise eyebrows, but she's got brains so sharp she's called a genius—blessing or curse. That's why her potions and contraptions occasionally cause chaos, earning her a rep as the ultimate eccentric. I asked what she made, and her answer hit me like a truck: this was the one I'd been looking for.
"Let's go meet her, then."
The woman I'm after is already a professor at her young age, doing research right here on campus. I got in touch through Hasun ahead of time and set up a meeting for today, but she was too lazy to come to me—"Figure it out and come here"—so now I'm tracking her down.
"Excuse me."
"Yeah? What do you want?"
I flagged down a grad student-looking guy with heavy dark circles under his eyes, and his reply dripped exhaustion.
"I'm looking for Professor Na Chae-myeong..."
"Huh? P-Pro-Professor Na Chae-myeong?! N-no idea!"
"Huh?"
I'd barely said the name, and the dude shrieked like a girl before bolting. I stood there dumbfounded. 'What the hell has she been up to?'
Professors can be scary from a grad student's POV, sure, but that reaction? It put me on edge too.
"Eh, it'll be fine."
I just wanted to see if she had any hypnosis apps or aphrodisiacs—minor stuff(?). So I headed to her lab.
"Professor Na Chae-myeong... not much older than me, and already a prof. AV World perks, I guess?"
The real world has its share of incomprehensible geniuses too, so a mid-20s professor isn't impossible. But that's not important right now.
*knock knock*
"Hi, I'm Seojin, Hasun's friend."
"Hasun? Come in."
The voice from inside sounded young, laced with heavy annoyance. I opened the door and stepped into chaos. Lab stuff everywhere—vials, papers, weird smells wafting around.
'Maybe this is perfect.'
I'm after an eccentric scientist who makes the unusual. The less normal, the closer she is to what I want.
"So you're Hasun's friend?"
"Y-yeah... Hi, Professor Na Chae-myeong."
She was buried in stacks of papers, not even glancing my way. I was stunned. 'Mid-20s? No way.' She looked way too young—like a high schooler. Five years older than me, but she seemed five years younger.
'Good thing Hasun warned me about her looks, or I'd have mistaken her for a student.'
She didn't look like any professor, but I knew this was her.

Messy red hair, face screaming "this is such a hassle." She shook a mystery vial in one hand and finally looked at me.
"So, what do you want?"
Her everything's-a-pain expression screamed mad scientist from hentai or manga, not porn.
"I'm looking for something I heard you might have."
I cut straight to it, no fluff. She didn't seem to mind—in fact, my directness got a faint smirk.
"I whip up all sorts of crap. What do you need?"
"Got any aphrodisiacs?"
"Aphrodisiacs?"
Her eyebrow twitched. She eyed me warily—probably thinks I'm out to misuse it.
"For fun with Hasun. Figured it'd be good."
"Ah, got it."
She nodded casually at Hasun's name. Hasun hides her lewd maso pig side from most people, but the prof knows. They've been tight since Hasun was little—one of the few she calls a friend.
"Can't give you any."
Flat refusal. I grinned. 'Not "I don't have it"—just "won't give." Means she does.'
There are plenty of weak aphro-like drugs, but nothing that fully breaks reason with heat? If she has it but won't hand it over...
"Can't I buy it somehow?"
"Got plenty of cash."
She's an eccentric who patents useful inventions amid the junk, raking in dough. Straight cash probably won't cut it.
"Do me a favor instead, and it's yours."
"What kind?"
I figured it'd take serious convincing, but she offered quick.
"Nothing big. Got an experiment coming up—need a specific ingredient."
She shook the vial and approached.
"Want you to provide it."
"Me? What ingredient..."
"Nothing much... Mind leaning forward a sec?"
"Sure."
No threat vibes, so I leaned in.
*sniff...*
"Huh?"
The vial hit my nose, dizziness hit hard, and I crumpled.
"Turns out I need some holy semen..."
Her playful grin was the last thing I saw before blacking out.
......................
"Perfect timing—fresh material delivered."
Na Chae-myeong chuckled casually as she dragged my unconscious body to the next room by the legs.
"Nngh... kinda heavy."
Smaller and slighter than average, even for a woman, she struggled but got me to a chair and strapped me down.
"Hasun's friend, so I'll milk him moderately."
She's researching female arousal and male pheromones lately, aiming for a universal attractant. Key ingredient: fresh, high-quality semen. She'd been pondering how to get it when I showed up begging for aphrodisiacs. Quick math, and now she's trading it for my load.
"If he's basically Hasun's boyfriend, should be fine."
Trust issues run deep for her, so a random stranger asking favors? She'd have called security already. But Hasun's man, and Hasun's like a little sis? Good enough.
"There. Can't move now."
Chair-bound, arms and legs secured—no escape without release.
"He gets aphro, I get cum. Win-win."
Prepped for refusal with knockout gas and restraints. She'll get what she wants.
"Great timing, really."
Knocking someone out and tying them up? Zero guilt. She's used to fallout after getting hers—process doesn't matter.
"Alright, pants off first..."
She stripped my pants for semen extraction.
*thud*
"Ooh... impressive equipment."
First dick she's seen, no big reaction. Curiosity and intellect always trumped everything—even sex.
"No wonder Hasun's into it. Solid size even soft."
Intrigued not sexually, but scientifically by the above-average girth.
"This'll yield top-tier semen."
Goal: maximum volume. Satisfied, she grabbed her prepped tools.
"Can he cum asleep? Experiment time."
Gloves on, lube and onahole in hand, she approached.
"Let's begin the experiment♥"
Her eyes sparkled brighter than ever as she grinned.
