EP 1. Education
After organizing her things in the room, Jieun followed her senior's suggestion to go eat.
The dining hall was large enough for more than twenty people to sit and eat at once.
Her senior walked to the end of the long table.
A naked woman lay prone on the floor there.
Without a second thought, her senior sat down on the woman's buttocks.
"What's wrong, Jieun?"
When she stared in shock, her senior turned and asked.
"That woman underneath you…?"
"Huh? What are you talking about, Jieun? This is just a normal 'chair,' isn't it?"
A chair?
But no matter how she looked at it, it was a person.
A person… a person?
Jieun rubbed her eyes.
Huh. It really was a chair… A slightly soft leather chair with nothing but a pair of heavy breasts dangling beneath it, the texture of skin faintly perceptible.
"Right?"
"Y-yes… It is a chair…"
Goodness, why had she been mistaken?
That thing was obviously a chair no matter how you looked at it.
Jieun glanced around for a place to sit.
However, aside from the "chair" her senior was using, there were no other seats in the dining hall.
"What's the matter, Jieun? Why are you looking around like that?"
"U-um, senior… Where are we supposed to sit?"
"Huh? Right there. That's the spot reserved for you and Violet."
Where her senior pointed, a white sheet and a dog bowl had been placed.
"Excuse me…? Over there…?"
"Why are you repeating it like an idiot? Obviously that's the place. Don't tell me a portable onahole like you was planning to sit at the same table as your big brother?"
Violet snorted and walked over to the sheet, kneeling down on it.
Even so, this kind of treatment was a bit…
"What's wrong, Jieun? I went out of my way to prepare a spot that suits you. You don't like it? Did I make a mistake?"
Her senior asked, testing her.
"What? Ah, no. I like it. Very much!"
Jieun shook her head in alarm at the thought that she might disappoint her senior.
"Really? That's a relief. Go sit down."
"Yes!"
Jieun quickly moved beside Violet and knelt down.
This wasn't so bad after all. In fact, it felt rather nice, Jieun thought.
She could look up at her senior from the front, and the sheet beneath her was soft enough.
Yes, yes. Her senior had really been considerate.
Realizing her senior's kindness, Jieun felt a warmth spread through her chest.
While she sat obediently like a puppy waiting, a maid brought food from the other side.
Her senior's table was laden with a lavish feast of over ten side dishes and main courses.
Meanwhile, a ladle poured a thin, porridge-like substance into Jieun and Violet's dog bowls.
A strong, unpleasant odor slowly rose from it.
"Um… Could I ask what this is?"
Jieun turned to Violet and asked.
Violet, who had been sitting in a "wait" posture and drooling profusely, whipped her head around and replied with an incredulous "Haa?"
"You really don't know anything, do you? I can't believe someone like you became big brother's girlfriend. Of course it's semen. What else would you put in your mouth-pussy?"
"So it was semen… Did big brother squeeze it out himself?"
"Ha? Are you broken or something? Even if it's big brother, how could he produce this much? This was collected from those pathetic pig bastards in the livestock pen. It can't compare to big brother's superior semen, but it's still edible enough."
"Pigs…?"
"Yeah. The pathetic, miserable bastards who had their women stolen by big brother and were left crying about it. They're not even worth calling men. After pissing off big brother, they had their personalities erased and ended up locked in the livestock pen. Serves them right."
Was that it?
Jieun didn't fully understand, but it seemed like those pigs were set up that way.
Semen extracted from pigs… Somehow that felt unpleasant.
The smell was awful too.
Plus, it was incredibly thick for semen.
Almost like half-melted jelly.
"You two can eat now."
Her senior said.
"Yes! Thank you, big brother!"

Violet answered energetically.
Slurp, lick-lick-lick, haa.
When Jieun turned toward the vulgar sounds coming from beside her, she saw Violet burying her face in the bowl, eagerly lapping up the semen.
"Huaaah♥"
A blissful smile spread across her usually cold, curt face.
She even trembled with emotion, like someone who had finally tasted delicious food after starving for days.
It seemed over the top, but watching her made Jieun's mouth water.
Jieun slowly lowered her head and licked the semen in her bowl.
As expected, it tasted different from the semen she had tried before.
It felt like it contained something extra.
But it was delicious.
The smell was foul, and there was an odd chewy texture in her mouth, but it tasted good.
Lick-lick-lick.
Gulp.
Slurp.
Lick-lick-lick.
"Huaaah♥"
How to describe it?
It felt like her brain was melting.
Her pussy throbbed, her body grew pleasantly hot, her head went blank, and she twitched uncontrollably.
The semen entering through her mouth-pussy rampaged inside her, pleasantly scraping past her throat and down into her esophagus and stomach.
It was as if her mouth-pussy, throat-pussy, and stomach-pussy were all being caressed at once.
"Heee…♥ Heh…♥"
Jieun's face flushed bright red as she panted heavily, fingering her pussy while diligently licking the semen from the bowl with her mouth-pussy.
The semen wasn't ordinary.
It was a powerful aphrodisiac mixture packed with various nutrients, drugs, and an ultra-potent estrus agent.
Even just applying it without eating would keep a man erect for over a day, and for a woman it would make her shove anything she could fit into her pussy.
"Hufuu… Ihit…♥"
"Aah…♥ Hehe…♥"
Lick-lick-lick.
Squelch-squelch.
Squirt.
With thoroughly disheveled faces, Jieun and Violet licked the semen while lost in masturbation, drooling up and down.
"Hauuung♥"
Jieun came midway and ended up wetting herself.
A stream of pale yellow urine sprayed out and soaked the floor beneath her.
Fortunately, the sheet laid out absorbed all the urine.
"Hihit♥"
After relieving herself comfortably, Jieun buried her face back in the bowl and resumed licking up the semen.
Beside her, Violet also lay prone, twisting her hips in ecstasy and laughing emptily before wetting herself as well.
"Ehe♥ Ehehehe♥"
It had been an incredibly happy meal.
***
After finishing their meal, Jieun and Violet followed Kang-hyuk out of the dining hall.
"Ehet…♥ Big brother♥ Big brother, big brother♥"
"Senior…♥ Senior…♥"
Both women wore dazed expressions as they kept fingering their pussies.
"Now that you've eaten, I should show Jieun, our new family member, around the mansion. Follow me."
"Yesh, senior♥"
"By the way, how long are you two planning to stand on two legs? Jieun might not know better, but Violet, you should be setting an example. Have you gotten cocky again already?"
Violet flinched violently, her body trembling, then immediately dropped to the floor.
"Ah, no. I'm sorry, big brother. I forgot my place for a moment. Please forgive me."
Violet crawled to her senior's feet and whimpered cutely.
"Don't come near me. You reek of semen."
Her senior kicked Violet away as he spoke.
Violet, who had been sent sprawling, knelt back up and looked up at him with a "hehe♥."
When Jieun watched with concern, thinking it was a bit harsh, her senior spoke.
"It's fine. It's just our usual play. You know how it is—siblings fight all the time."
"Aha… I see."
Thinking back, Jieun had often fought with Jia when they were young too.
Of course, it had only ever been verbal arguments, and she had never used violence.
But that was probably just how each household was different.
Violet seemed to like it too.
"You should get down too, Jieun."
"Ah, yes, senior♥"
Jieun crouched on the floor like a dog.
This was the etiquette of this household.
If so, she had to follow it as well.
After all, she was now family with her senior too.
The thought excited her.
Family with senior…♥
"Good girl. Let's go then."
The two of them crawled on all fours, following behind Kang-hyuk.
Despite the mansion's size, there didn't seem to be many rooms in use.
After touring the study, recreation room, music practice room, laundry room, and reception room, her senior led them down to the basement.
"This is the punishment room."
After passing through a narrow corridor and opening the door, a rather bleak and unsettling scene unfolded.
Inside, things like whips and sharp skewers hung on the walls, and on one side stood a tall, long bed resembling an operating table.
On another side was a separate space partitioned off by iron bars.
It looked exactly like a prison cell.
The purple stains scattered throughout the room were strangely unsettling.
No matter how she looked at them, they appeared to be bloodstains that had dried and discolored.
"It's literally a place for people who need punishment. But we never use violence against anyone's will. Punishment only happens when the person themselves wants to repent. Right, Violet?"
When her senior called her, Violet, who had been trembling in fear ever since entering the basement, flinched and answered.
"Y-yes! Big brother!"
"Violet came here before too, didn't she?"
"Y-yes! I did!"
"And you received punishment because you wanted it yourself?"
"Yes! As a cheeky bitch who doubted big brother, talked back to him, and above all tried to harm his body, I asked big brother to punish me so I could repent…!
Big brother… Big brother gave me plenty of drugs to fix my bad habits…♥ Until my head went all mushy and my masochistic nature was fully injected…♥ And while doing that, he whipped my ass over and over…♥"
"And then?"
"And then…♥ Big brother removed all the things Violet didn't need…♥ For example, my teeth…♥ Because I had the nerve to bite big brother…♥ To make sure it never happened again, he pulled out all my teeth♥ And put in soft dentures instead♥ He said I wouldn't need them anyway since I'd only be eating semen from now on♥ And because I scratched him with my nails, my nails too… Ihit…♥"
Violet trembled and leaked a bit of urine.
"And then?"
"And then… When this arrogant bitch still showed no signs of repenting… He pulled out all my hair♥ It was sad at the time, but instead I got beautiful new hair through a transplant… So I was very happy…♥ And also♥ Because my pussy and back-pussy were inappropriately tight♥ He forced them open until his arm could fit, turning them into ruined holes♥"
Violet said this while spreading her rear hole.
Now Jieun could see a small nipple-like protrusion sticking out.
"Jieun, try pulling it."
"Huh? Ah… Yes."
Jieun carefully grabbed the protrusion and pulled.
Then—
"Ohoooook♥"
Violet let out a bizarre moan, and a large black bead began to slide out.
It was nearly the size of a fist.
And it wasn't just one—more and more kept coming out the harder she pulled.
"Ihi♥ Euh♥"
"Wooow…"
"What do you think, Jieun? What are your thoughts seeing this?"
Her senior asked.
Jieun glanced at him cautiously before speaking carefully.
"It's a bit… vulgar, I guess…"
Honestly, she wondered if it was too much, but since Violet had wanted it herself and there was surely no fault on her senior's part, Jieun vaguely assumed.
"There's still one more thing left. Right, Violet?"
"Yesh♥"
Violet answered with a smile full of flattery, then peeled off the heart-shaped sticker on her nipple.
She then grabbed her erect nipple with her fingers and spread the center open.
The nipple stretched open surprisingly wide, revealing the bumpy interior.
"And big brother also♥ Surgically modified my useless nipples so milk would come out even without pregnancy and I could easily fit fingers inside♥ And also♥"
Violet inserted her index finger into the nipple and thrust her hips, letting out a strange moan.
"Ohoook♥ Ah… He made the inside sensitive… So it could be used for masturbation too♥"
"And as a result, you became a good little sister?"
"Yes♥ Violet has become a good, diligent little sister who obeys big brother…♥"
"That's great. Right, Jieun?"
"Huh? Y-yes…"
Jieun was flustered.
How to put it—it felt like something was off, but she couldn't quite grasp what.
If someone did wrong, received punishment, repented, and changed, that wasn't a bad thing.
So her senior was probably right, but… huh…
Well… Whatever.
"That's… good."
