The Nightmare's Box – A Hardcore Play
Nightmare's Box has been acquired.
A demonic artifact from the Demon Realm. Capable of plunging a captured human into any dream of extreme pleasure or torture at the user's command.
From the other world came one of those alien artifacts. Among them, the long-eared, beautiful elves specialized in healing potions and items for recovery. Meanwhile, the horned demons of the demon race focused on destructive and lethal tools. The Nightmare's Box belonged to the demons.
It was a device that could trap a human inside and force them into a desired dream.
A young male high-school student whose hormones were boiling like crazy would have begged for this exact thing: to experience a filthy dream. Yet in reality, it was an incredibly terrifying apparatus.
There was no limit to the range of dreams it could create. Whether it was a dream of making love to a heavenly beauty or the nightmare of being dipped alive into a pot of boiling sulfur while his skin was stripped away—it all belonged to the user to control however they wished.
And when the worst villains got their hands on it, the result was precisely this.
Extracting the PrPc component that transformed under extreme pain and using it to manufacture drugs.
Even the demon magicians who stuffed victims into the box, subjected them to hellish torture until their brains melted, and ground their brains into powder were silenced by this project.
I couldn't understand why that bastard Jungu Lee had gone this far into demonic deeds, but if placing this box over someone's head guaranteed I could make them dream exactly what I wanted, then...
“This is something I've never used before, so I'm curious.”
All the serious magical items from the other world carried insanely high prices. The cheapest one already exceeded the cost of a building.
Calculating the price of something as versatile and effective as the Nightmare's Box was impossible even for me.
“Is this it…”
A cube-shaped box, translucent crystal.
It was a tool perfectly suited for torturing and breaking a mind like Lee Yohee's. It would become an invaluable aid in the future training.
If I used this to reduce Yohee to complete submission, the youngest daughter of the Lee family of the Samjung Group could even take on the role of an internal whistleblower, exposing her own family's corruption and scandals.
But to do that, I first had to fix her infantile regression.
A witness on the stand declaring herself an internal whistleblower while babbling nonsense like a madman—that was something no one would believe. On the contrary, they might turn around and accuse me of abusing that poor girl just to stage a performance.
Ultimately, I had to bring Yohee back to normal.
Sigh… It was genuinely frustrating that I had to do something for that bitch dog.
Cognitive behavioral therapy was out of the question. I wasn't qualified to handle such advanced psychological treatment.
I'd even imagined using the Nightmare's Box for dream therapy, but it wouldn't work. Hypnotists themselves couldn't control dreams that deeply penetrated the subconscious, let alone me with my limited skills.
It might even worsen her infantile regression.
So the only remaining alternative was medication. Didn't this house have some psychoactive pharmaceuticals?
Following that thought, the shelves in the education room were filled with dozens of medicine bottles.
“Let me see…”
First, an anti-anxiety drug to stop her from clinging and acting like a separated dog. Then, an antipsychotic—benzo or risperidone.
I picked up the bottle labeled with those names and noticed another interesting one beside it.
Addy.
The raw material for Plimax liquid. An ingredient in Flibanserin drugs.
It wasn't just a simple stimulant. It chemically altered a woman's brain itself over several weeks, amplifying her libido and sensitivity. Unlike instant drugs, it gradually changed the body. If I fed this to Yohee whenever she was regressed, I would see dramatic results when harvest time arrived.
I headed to the kitchen, prepared a light breakfast with the medicine, and carried it upstairs to her room.
Knock knock.
“Miss, this is Kim Sunghyun.”
“Waaaaah! Sunghyun!!”
Bam!
The moment I opened the door, two enormous breasts swinging wildly in the air came into view.
Jiggle♡ Jiggle♡
It seemed she had taken off her bra because it was uncomfortable while sleeping.
Still, she was wearing the white shirt she always wore, but with no skirt or panties, the massive breasts and pink nipples on top were shamelessly visible.
Even if I hated her mentally, her body reacted as it should.
I wanted to flip this cow-like bitch and force impregnation, but I couldn't do that yet.
“Are you horny, Miss? Want some food? Heehee, I'll feed you.”
I placed a sandwich in her mouth as soon as I saw her.
“Aaaah~ Hwub… Nom nom.”
Slurp slurp.
The face that looked like a classic villain was melting into goo like this. Did she have no innate evil?
“Kk… Hic… I drank it.”
Unable to feel shame, Yohee took a tiny belch and licked the mayonnaise clinging to her lips with her tongue.
“Miss, this is a good vitamin. Swallow it all at once with water.”
“Eek!? Uuuh it's bitter… Medicine tastes gross.”
“Still, try eating a little.”
“Gross! I won't eat! Gross gross gross gross!!”
I felt my fist clench involuntarily and almost slapped her face, but I endured with superhuman patience.
Forcing her mouth open and shoving the pill in would be easier than twisting a child's arm, but I didn't dare. Who knew how far her mental state would deteriorate?
“Sigh… If I just want you to eat a little… eat… No? What should I do?”
“Hmm? Ah… then th-that~”
She shook her body left and right while speaking in a sweet tone. What was she trying to say while acting so bashful?
“If you eat the medicine well, I'll give you a kiss!”
Bullshit…
This bitch dog.
“What are you saying?”
“Ah why! Do it! If I have to, I'll do it! Then I'll eat the medicine.”
When had I ever felt this intense irritation with a woman?
Every single action drove me crazy.
“Sigh…”
But I had to hold it back.
If I kept feeding her only these “therapeutic” preparatory drugs, I would be able to finish her off more easily in the future.
“Understood. Then open your mouth.”
“Uuuoot… Uhehe! Aaaah~”
I popped three pills into her small mouth that she opened like a bird begging for food, then handed her a cup of water. She swallowed them perfectly. It wasn't actual infantile regression; she was just an adult woman's throat, so no choking occurred.
“Uuu… The medicine tastes gross.”
“Excellent. Then that's all for now.”
“Where are you going!!”
As I tried to sneak away, Yohee grabbed my wrist and pulled me toward herself.
“Kiss!”
She closed her eyes, cheeks flushed, and pouted while making a smooching sound.
‘There really are crazy bitches like this. Damn.’
Expressing affection or craving love was advancing at an absurdly abnormal speed.
It seemed she had suffered tremendous affection deprivation since childhood.
“Quickly!”
Yohee was still sticking her lips out toward me.
I closed my eyes tightly, then pressed my lips against hers.
Smack.
“Kyaa! Fufuhee!! Kissed!”
“Then I'll be going.”
“Fuuh! Fufuheehee!!”
I left her, face buried in the pillow and kicking the bed furiously, to her own madness.
“Kyaaak! Kkuk!”
Spit thick phlegm and wiped my swollen lips with my sleeve, but it still felt gross.
Walking down the hallway with my face twisted in anger, I accidentally passed a corner and saw Cha Seyeon.
“Cha Seyeon.”
“Who dares call me by name… Heuk, Master, hello.”
The moment I called her name, Seyeon came running with proper steps and stood before me.
“Stay with me for a moment.”
“Y-yes?”
“What is that stupid talk, you toilet girl. Can't you understand? Because you're dying for cum, call yourself a semen receptacle.”
I was experiencing both disgust and irritation because of Yohee, so I needed to vent some stress.
“Uuh…♡ Y-yes… Uuhh…”
Seyeon licked her lips once, then followed behind me.
‘Since it's like this, should I use the Nightmare's Box on Seyeon?’
It sounded like it would make for some fun hardcore play.
“Oh? Master, the stairs to the basement are this way…”
“Don't talk nonsense and follow. You're a toilet girl, yet you can't obey my orders?”
“Ah, ah! N-no! Sorry! I'll go anywhere Master wants and serve as a semen receptacle faithfully!!”
When I glared at her with a fierce face, Seyeon was startled and replied while standing at attention.
Squeak—
I had found the basement again.
The assistant director didn't need to worry.
The moment I gave him the makeshift title of butler right after Yohee, I had told him that from now on I would personally handle the basement 'raw materials' management, so he could use his free time for personal hygiene.
The assistant director had finally let out a sigh of relief and left happily. As long as nothing special happened, no one would come looking for the basement.
I grabbed Seyeon's wrist and dragged her into the room where the Nightmare's Box was.
Click.
When I locked the door, Seyeon, with a slightly tense expression, asked.
“Ma-Master… excuse me, but why this room…?”
She knew exactly what kind of room this was.
The room where countless victims had been tortured with hellish pain.
The first step to turning this into a training room was using this woman's body.
“Take off your clothes.”
