I Got Hired at the Cafeteria, Ya Know
Yeonsaeng sat on the bed and stared at the cock that had suddenly sprouted from her body.
"Think it over, Yeonsaeng."
Yeonsaeng pondered why a man's member had grown on her.
And one possibility came to mind.
"Reckon that's probably it, ain't it? Open the physical traits section of the privileges."
The moment Yeonsaeng spoke, a window displaying the physical section of her Irregular Privilege System appeared before her.
Physical Traits
1. Supreme: The user always maintains peak physical condition.
2. Invulnerability: No blade or magic can inflict injury upon the user's body.
3. Yin-Yang Dual Body: The user's sex is female, yet she possesses male genitalia.
3-1. Yang-Energy Abundance: Failure to regularly ejaculate semen will result in entering a state of estrus.
3-2. Enhancement: Capable of strengthening the abilities of any partner she ejaculates into.
3-3. Subjugation: Able to bind any partner she ejaculates into according to her will.
3-4. Pheromone: The user emits pheromones that seduce and induce estrus in partners (females only). Effects vary greatly depending on the partner's mental fortitude.
3-4. Estrus Level: The user can check her current estrus level before reaching the threshold of 3-1.
The mysterious question marks that had filled the entry when the Irregular Privilege System first opened were gone. Seeing Yin-Yang Dual Body written there instead, Yeonsaeng knew her guess had been correct.
"Just as I reckoned, I was right."
Yin-Yang Dual Body.
As the name implied, it meant possessing both a yin body and a yang body. That was why a cock had grown on Yeonsaeng.
"Still, what in tarnation does it mean that if I don't regularly shoot out semen I'll fall into heat?"
Her words were not a question about the explanation itself. They were a lament over the penalty.
"Reckon I ought to check? Show me my estrus level."
Physical Trait 3-4: Estrus Level Information
Current Estrus Level: 78%
Yeonsaeng's current estrus level stood at a staggering 78 percent. It was proof that the condition had built up considerably without her noticing.
"Why's it so high?"
The moment she became aware of it, a tingling sensation shot through her entire body.
"Ugh♥ What's happenin' to me?"
Throb!
With that electric jolt, Yeonsaeng's cock stood ramrod straight.
"Haa... haa...♥"
Estrus Level Increased
78% → 85%
In that instant her estrus level shot up by seven percent. Yeonsaeng realized that if she didn't take care of it right now, she would fall completely into heat and turn into a drooling, lust-mad wreck.
"Ain't no help for it..."
Yeonsaeng decided to masturbate. Normally a proper maiden would have preserved her dignity, but such thoughts no longer existed inside the current Yeonsaeng.
"Hngh♥"
Merely wrapping her hand around her cock sent a piercing pleasure straight into her brain that began to dominate her whole body.
"Haaaaah♥"
Slap! Slap! Slap!
She started stroking her cock up and down. Every motion paralyzed her mind with ecstasy.
"Khhng♥ This... feels mighty fine... haaah♥"
Her hand moved faster, rougher. The pleasure kept spiking.

"Khaaaaaah♥ I'm comin'!"
Spurt! Spluuuurt! Spluuuuuuurt!
At the peak of climax, thick ropes of semen erupted from Yeonsaeng's cock and gushed outward.
Estrus Level Decreased
85% → 24%
Along with her ejaculation, a notification appeared stating that her estrus level had dropped. But Yeonsaeng's eyes did not register it at all.
"Haa... haa...♥"
Still burning with arousal, Yeonsaeng began masturbating again. She wanted to savor this pleasure a little longer.
Slap! Slap! Slap!
Her frantic self-pleasure continued until her estrus level finally reached zero percent.
"Ugh... I'm beat..."
Maybe it was because she had masturbated so fiercely the night before? Yeonsaeng felt like she might drop dead from drowsiness. But she could not sleep. Today she had to head to the Demon Group Headquarters.
Once inside the massive building, Yeonsaeng made her way to the reception desk.
"Welcome. How may I help you today?"
The receptionist offered the practiced service-industry smile and asked Yeonsaeng's business.
"I'm here to see the team leader of the Mut HR department."
"You mean Director Mut? Do you have an appointment?"
"Yeah. Made one yesterday, I did."
"Understood. One moment while I confirm."
The receptionist picked up the phone and pressed the button for the HR department. After receiving confirmation, she set the receiver down and spoke to Yeonsaeng.
"You're cleared. Take the elevator over there to the third floor. The HR department is right there."
"Much obliged."
Yeonsaeng gave a polite bow and stepped into the elevator as directed.
"Hold up a second."
Just as the doors were about to close, Yeonsaeng saw someone sprinting toward the elevator and quickly pressed the open button.
"Huk... huk... Thank you."
"No need for thanks. Looked like you were in a hurry, so of course I'd wait."
A woman with short silver-white hair boarded. The elevator doors slid shut once more and quickly rose to the third floor.
"Jerin, late again I see."
The moment the doors opened, Mut—the head of the HR team—was standing right there.
"Sorry, Team Leader. I didn't hear my alarm and overslept."
"Tsk... Spare me the lies. I know you went clubbing last night."
"Chit... Busted, huh?"
"What was that?"
"Nothing at all. Oh, right—I have documents to organize."
The silver-haired woman, Jerin, dodged Mut's scolding and hurried to her desk. Watching her, Mut clicked her tongue, shook her head, then turned to Yeonsaeng.
"You've arrived. Follow me."
"Got it."
Yeonsaeng answered and trailed after Mut.
"Yeonsaeng, correct?"
"Yep, that's me."
"I'd like to know what brings you to the Demon Realm."
Yeonsaeng considered how to answer. Saying she had suddenly appeared here would obviously not be believed.
"I heard this Demon City was a fine place for a lowly commoner like myself to live. So here I am."
"You think this is a good city to live in? Pfft... Bwahahaha!"
Mut burst out laughing at Yeonsaeng's reply.
"You genuinely believe this is a good place to live?"
"Yeah..."
What was so funny? Yeonsaeng could not understand why Mut was laughing. Was there something wrong with what she had said?
"It's half true that it's livable. Well... never mind that. Do you have any special skills?"
"Special skills? Why're you askin'?"
"Because I need to know."
"If it's special skills... this one's good at cookin' food."
"Cooking, hmm..."
The reason Mut asked was simple. She had judged Yeonsaeng as a dangerous element. Yesterday she had watched a clumsy lower-class street robber's blade shatter into pieces the instant it touched the woman's cheek. At that moment Mut had thought, That... is dangerous.
She had even considered eliminating her. But her instincts told her she probably could not, so she abandoned the idea. If she could not get rid of her, the next best thing was to keep her close and watch her. Thus Mut decided to make Yeonsaeng an employee of the Demon Group.
Of course she needed proper justification. Asking about special skills was the perfect excuse. After all, placing someone where their talents were most useful was an ironclad reason.
"Would you like to work for our company?"
"By company ya mean the Demon Group?"
"Correct."
Yeonsaeng did not hesitate. She had no other choice. This was not Joseon. In fact, it was not the world she had once lived in at all. She had nowhere else to go. When someone offered her a job under those circumstances, what else could she do but accept?
"Yeah. I got plenty of will to work."
"Good answer. In that case... the company cafeteria would be perfect. They've been hounding HR nonstop about being short-staffed."
"Just put me to work and I'll do my best."
"Then spend today observing how things are done. You'll start in earnest tomorrow."
"Understood."
And so Yeonsaeng was hired at the Demon Group cafeteria.

"I have no idea where you found such a talent. I was right to trust Team Leader Mut after all."
"My goodness, Big Sister. Weren't you badmouthing Team Leader Mut until yesterday? And now you're saying this?"
"W-when did I ever do that!"
Isola, the vampire in charge of the company cafeteria and affectionately called Big Sister by her staff, was utterly taken with the new hire who had arrived yesterday.
Not only did the newcomer handle the work of several people by herself, but the moment Isola tasted her cooking she thought, Ah... everything I ate before was garbage. The flavor was heavenly—no, since they were demons, it was like falling straight into the abyss of flavor.
It was only natural Isola would think so. Yeonsaeng possessed a cooking skill that always maintained the highest possible taste while also raising the favorability of anyone who ate it. Isola's affection had skyrocketed.
"Big Sister, try this and tell me if it's good enough to serve today."
Yeonsaeng held out a plate of freshly made bulgogi. Normally a new hire would never do something so forward, but with Yeonsaeng it was different. Isola actually wished she would make even more.
"Let's have a taste, shall we?"
"Big Sister, let me have one bite too—"
"Hey! The adult gets the first taste!"
Isola picked up a piece of bulgogi with her chopsticks and put it in her mouth. The beef should have been tough since it came from an aged demon-world cow, yet an unbelievably tender texture conquered her tongue. The meat melted like the finest demon beef grilled to perfection. By the time Isola came back to her senses the plate was already empty.
"What? Where did it go? Helli! Did you eat it?!"
"What are you talking about... You inhaled it like a storm while I didn't even get one bite!"
"Ahem... This will have to go on the menu today."
Indeed, the bulgogi was delicious enough to change the entire lunch lineup. That day the special bulgogi was served, and the reaction was explosive.
"What is this? This isn't Big Sister Isola's cooking, is it?"
"It melted away without even needing to chew?"
"Hey! If you want more, go get your own! Why are you stealing mine?! I've only had one bite!"
The Demon Group cafeteria operated on a self-service system. And into that system had appeared the overlord known as Yeonsaeng's bulgogi. Lunchtime that day turned into an absolute battlefield as employees fought to claim the overlord for themselves.
