The Assistant Manager Seduced Me First
One week had passed since Yeonsaeng started working at the company cafeteria.
The employees of Demon Group Headquarters had become utterly dependent on her cooking. They literally could not live without it anymore.
“Isola, awaken already!”
“Isola, bring out Yeonsaeng’s food right now!”
“Why aren’t you serving Yeonsaeng’s dishes today?!”
A crowd of employees was staging a sit-in protest right in front of the cafeteria kitchen.
The whole uproar had begun when Isola declared that Yeonsaeng’s food would not be served that day.
The incident traced back to that very morning.
“Big Sis, today I’m making bomdong bibimbap.”
“Bibimbap? What’s that?”
It was a dish Isola had never heard of.
“You put freshly cooked rice in a bowl like this, then add the star ingredient—spring cabbage…”
Yeonsaeng summoned a large metal mixing bowl with her skill, scooped in steaming rice, and topped it with seasoned bomdong kimchi.
“Then you just add this gochujang and mix it all up real good. That’s all there is to it.”
Yeonsaeng stirred the rice thoroughly with a spoon and handed the bowl to Isola.
Though it was a completely unfamiliar dish, Yeonsaeng’s skills had already been proven beyond doubt. Isola took a big spoonful without hesitation and put it in her mouth.
The moment it touched her tongue, the bold punch of gochujang slammed into her senses. It was intense, but in the best possible way.
After the spicy heat swept through, the crisp, refreshing fragrance of the spring cabbage cleaned her palate perfectly.
“This is…!”
Isola’s eyes flashed with excitement.
Then, as if possessed by a hungry ghost, she began devouring the rest at lightning speed.
“You called it bomdong bibimbap, right?”
“Yep, that’s right.”
Isola thought to herself.
Do I really need to put this on today’s menu?
If I don’t serve it… couldn’t I keep it all for myself?
It was an utterly selfish idea, but she was the kind of woman who could entertain such thoughts without shame.
And so she decided.
I’m never putting this on the menu. I’m going to eat every last bite myself.
Unfortunately for her, one of the three cafeteria staff members—Helli—had overheard the decision. Outraged at the idea of Isola monopolizing it, Helli immediately spread the rumor. That was how the protest had erupted.
“No. I’m not serving it. Eat something else.”
Isola was firm.
The vampire’s legendary possessiveness had exploded after tasting Yeonsaeng’s bomdong bibimbap.
“Storm the kitchen!”
“Seize the treasure known as bomdong bibimbap!”
“Overthrow the cafeteria dictator!”
The employees were about to charge into the kitchen when someone stepped forward to block their path.

“Y’all can’t come in here.”
It was Yeonsaeng.
“The kitchen is a space only for kitchen maids and pantry maids. If y’all insist on comin’ in, I’m tellin’ ya right now—I’ll go on strike startin’ tomorrow.”
“Ugh…”
At her words, the employees froze.
If they had to choose between today’s bomdong bibimbap or Yeonsaeng’s future dishes, the latter was obviously the smarter choice.
They had no choice but to retreat.
“Instead, I’ll serve y’all somethin’ else.”
Yeonsaeng brought out jeyuk deopbap—spicy stir-fried pork over rice—in place of the controlled bomdong bibimbap.
As soon as the employees saw one of her three soul foods—spicy stir-fried pork, pork cutlet, or pork-and-rice soup—piled generously over steaming rice, they swarmed the serving line like locusts.
Tsk… It’s a shame, but I guess it can’t be helped.
Isola felt a pang of regret in her heart.
If she tried to monopolize even this, upper management would probably force her to write a formal apology letter. She decided to settle for keeping the bomdong bibimbap all to herself.
The pantry at Demon Group was normally stocked with all kinds of snacks, so it was usually packed with people who claimed they “absolutely couldn’t eat Isola’s cafeteria food.”
But ever since Yeonsaeng started working in the cafeteria, not a single person came to the pantry during lunch anymore.
Thanks to that, Yeonsaeng could enjoy the break room in peace.
“These here potato chips are somethin’ else. Real tasty.”
The salty crunch had completely won her over.
“Just goes to show big corporations know how to make the best snacks.”
Yeonsaeng rarely ate her own cooking. Since she made it for others, she only tasted enough to check the seasoning.
Even though her dishes were boosted by her cooking skill, she never felt any particular excitement about them.
In contrast, the snacks from this world really appealed to her.
“Next, I oughta try these chocolate chips.”
She had wanted to try them the first time she visited the pantry, but they sold out too quickly because of the crowd. Now she could finally enjoy them at her leisure.
“Oh my, Yeonsaeng. Hello there.”
Yeonsaeng paused mid-chew and looked toward the voice. Jerin was standing there.
“Well if it ain’t Assistant Manager Jerin. Howdy.”
“You’re having snacks? Didn’t you eat lunch?”
“I already ate, sure enough. And I heard there’s such a thing as a separate stomach just for snacks.”
“That’s actually true.”
“So did you come here for snacks too, ma’am?”
“No, I was just going to make myself some coffee.”
“I see.”
Yeonsaeng nodded and went back to enjoying her chips.
Hmm… What should I say? Just looking at Yeonsaeng is making my lower belly throb…
The moment Jerin stepped into the pantry, she felt a strange heat pulsing below her navel.
It felt almost like she had been hit with a succubus’s seduction spell.
What Jerin didn’t know was that the pantry was currently filled with pheromones released by one of the four effects of Yeonsaeng’s Yin-Yang Dual Body trait.
Even a lust demon like the succubus Jerin was affected. Her estrus level was rising in real time.
If her current arousal were expressed as a percentage, it sat at 67%.
Ugh…♥ This is… I can’t…♥
She had only planned to make coffee and return to the HR office, but her arousal had already shot past 80%. Jerin could no longer hold back.
If she didn’t relieve it immediately, she wouldn’t be able to focus on work at all.
Her gaze naturally returned to Yeonsaeng.
I can feel yang energy coming from Yeonsaeng… Haa♥
As a succubus specialized in detecting yang energy, Jerin could clearly sense the powerful flow radiating from her.
Yeonsaeng should have been a woman who only possessed yin energy, yet both forces coexisted inside her.
This is… just to confirm, that’s all♥
Jerin licked her upper lip and walked toward Yeonsaeng.
Yeonsaeng was wondering what to eat next when she noticed Jerin approaching.
“Assistant Manager, ma’am, you got somethin’ to say to me?”
“Um, Yeonsaeng… Please don’t think too badly of me.”
With those words, Jerin slipped off the jacket she was wearing.
Her voluptuous figure was revealed, along with the micro-bikini she apparently wore under her clothes every day.
Wearing a micro-bikini instead of normal underwear was simply Jerin’s personal preference.
“A-Assistant Manager, ma’am! What in the world are you doin’?!”
Jerin’s sudden action left Yeonsaeng visibly flustered.
And the moment she laid eyes on that seductive body, Yeonsaeng’s own estrus level began to skyrocket.
Arousal Level: 5% → 52%
Her arousal had shot up in an instant.
The moment it crossed 50%, Yeonsaeng’s crotch began to swell. Her massive cock started to push visibly against her clothes.
“My, my… You’ve been hiding something this magnificent?”
“W-what are you even sayin’?!”
Jerin licked her upper lip once more, then yanked Yeonsaeng’s pants down in one smooth motion.
“Hya?! What the heck are you doin’?!”
Yeonsaeng panicked and tried to pull her pants back up, but Jerin was faster.
She stripped the pants off completely and tossed them into a corner of the pantry.
Then Jerin pulled down Yeonsaeng’s underwear as well. Her long, enormous shaft sprang free.
“This is going to be delicious.”
Jerin licked her lips and brought her mouth to Yeonsaeng’s cock.
“S-stop that right now!”
Despite Yeonsaeng’s protest, Jerin’s lips enveloped her length.
“Haa♥”
“Slurp… sluuuurp♥ Sluuurp♥”
Jerin’s mouth began sucking Yeonsaeng’s cock like a vacuum cleaner.
This is… incredible.
As a succubus who had tasted countless cocks, Jerin knew Yeonsaeng’s was truly special.
That was only natural. Yeonsaeng was constantly under the effect of her powerful system privileges.
Even when idle, she released pheromones. Now that Jerin had taken the very source of those pheromones directly into her mouth, the amount flooding her body was enormous.
“Sluuuuurp♥”
Gulp… gluuuurp—!
Every time she sucked, Jerin’s arousal level skyrocketed. And with every surge, a flood of love juice poured from her pussy.
Arousal Level: 52% → 92%
Once Yeonsaeng’s arousal passed 90%, any trace of reason had long since flown out the window.

“Haaaaangh♥”
Spurt—! Spluuuurt—!
Yeonsaeng’s cock swelled as thick ropes of cum flooded Jerin’s mouth.
“Gulp! Gulp!”
The moment she swallowed Yeonsaeng’s semen, Jerin felt it.
My magic power is rising?
Magic power was the very source of a demon’s strength.
She could feel it increasing in real time with every swallow of Yeonsaeng’s cum.
Yeonsaeng… You’re exactly the person I’ve been looking for.
Succubi were lust demons.
Lust demons were a race driven by endless sexual desire. The reason they craved and hungered for sex was to replenish their magic power.
But the instant she drank Yeonsaeng’s semen, Jerin felt destiny.
With every swallow, she was gaining magic power that would normally have taken fifty years to accumulate.
After swallowing every last drop, she thought: If just a blowjob gives this much… how incredible would it feel to take it straight into my womb?
“Haa… haa…♥”
Yeonsaeng caught her breath, thinking it was finally over.
But Jerin had no intention of stopping here.

“Yeonsaeng, wouldn’t it be a shame to stop now?”
Jerin spoke while shaking her hips invitingly toward her.
“A-Assistant Manager…”
The moment Yeonsaeng saw that seductive movement, her arousal—which had dropped after the blowjob—rebounded violently. Her cock stood rock-hard once again.
“Oh my♥ So energetic♥”
Yeonsaeng decided not to resist anymore.
She couldn’t find a single reason to refuse.
If the person doing the seducing was the one at fault, then she would gladly accept.
“…… You started this first, Assistant Manager.”
Yeonsaeng grabbed Jerin’s hips with both hands and thrust her massive cock straight into Jerin’s dripping pussy.
“Khhhaaaangh♥ This is it♥ Haaangh♥ It’s even better than I expected♥”
“I’m gonna go a little rough now.”
Yeonsaeng began slamming her hips with powerful strokes.
The inside of Jerin’s pussy was softer than the yongsu jelly she had once eaten and warmer than a steaming hot pot.
“Khhhoooongh♥ You can be even rougher♥ Haaangh♥”
Yeonsaeng’s cock was far superior to any of the men Jerin had experienced before.
No—it wasn’t even on the same level.
This… was truly destiny.
“Hooooooongh♥”
“Uuuungh♥”
The lewd cries of Yeonsaeng and Jerin filled the entire pantry.
Yeonsaeng is mine♥
Since she had discovered her first, it was only natural that Yeonsaeng belonged to her. That was the possessive mindset of a succubus who had chosen her fated partner.
“Uuungh♥ I think I’m about to cum. Better pull out now.”
“Hoooongh♥ No, it’s fine if you cum inside♥”
“But if I finish inside…”
“I’m a succubus. I can control my own contraception, so it’s perfectly fine♥”
Succubi could indeed regulate their own fertility at will.
But Jerin had zero intention of doing so.
Bearing the child of her fated partner was the ultimate wish of every succubus.
“Alright then… Here I come!”
“Haaaaangh♥ Come as much as you want♥”

Spurt—! Spluuuurt—! Spurt—!
Yeonsaeng’s thick cum began flooding Jerin’s womb until it was completely full.
Drip… drip…
The excess semen and love juices that couldn’t be contained spilled onto the floor.
Ah…♥ This is it… This is exactly it!
The moment her womb received the cum directly, an enormous amount of vital energy and magic power—enough to take hundreds of years to gather—filled her in a single instant.
Arousal Level: 100% → 0%
With her climax, Yeonsaeng’s arousal finally returned to normal. Her reason came flooding back.
Whew… It’s finally over.
She swore she would never do something like this again.
She hadn’t felt like herself at all.
Judging by the look in Jerin’s eyes, Yeonsaeng resolved to stay out of her sight for the foreseeable future.
