Leona von Garcia
The next morning.
Not even half a day after Gaia had applied a light pressure to the Imperial Court, the mansion’s massive front doors were thrown open with a violent crash.
"I am Leona von Garcia, the eldest daughter of the Imperial Court, conscripted to assist the Hero Aria in her subjugation of the Demon King."
A beautiful blonde girl dressed in a flamboyant imperial gown stepped inside. Leona, the Empire’s greatest genius mage and a woman who prided herself on her haughty, aristocratic nose, walked in with a haughty gait.
However, contrary to her confident exterior, Leona’s pupils were trembling ever so slightly.
'Crazy, this is insane...! Why on earth did I have to possess a body in the 19+ adult web novel "In My Space, My Word Is Truth," and why did I get dragged into this den of evil?!'
In truth, Leona was a transmigrator who had lived in modern-day South Korea.
Mistaking this world for the setting of the novel she had read, she had buried herself in a corner of the Imperial Palace, hiding away to avoid a monster named 'Jin Sang-gun' who supposedly possessed brainwashing abilities. But in the face of a mandatory summons from Gaia, the supreme deity of the universe, the power of an Imperial Princess was utterly useless.
'I must treat this strictly as a business relationship. I’ll just stick to Aria’s side, pretend to help with the Demon King subjugation, and look for an exit strategy. I must never even make eye contact with the original protagonist, Jin Sang-gun...'
"Oh? The Princess is here? Hi!"
Just then, in the middle of the living room, the black-haired Hero Aria approached, waving her hand brightly.
The moment Leona’s gaze landed on Aria, the Princess’s entire cognitive circuit ground to a halt.
The Hero Aria was completely naked, without a single thread of clothing. The only things attached to her were dainty 'pink heart patches' covering her voluptuous nipples and the secret crevice between her legs, from which honeyed nectar was dripping.

"...Huh? Uh, uh?"
While Leona was unable to speak due to the shock, Gaia, who was neatly bringing out tea from the kitchen, also walked out wearing the exact same naked heart-patch attire.

"Welcome, Your Highness. I am Gaia, the bitch who serves the Master."
'Insane...! She’s already been brainwashed by that original protagonist bastard and turned this place into a den of depravity?! The Hero herself is walking around with nothing but heart patches on her crotch?!'
Just as Leona was about to step back in terror, I, who had been lounging comfortably on the sofa, chuckled and stood up.
My pants zipper was wide open, and thanks to Gaia’s diligent sucking throughout the night, my massive, stiffened center stood proudly before Leona’s eyes, showing off its majesty.
"Nice to meet you, Princess. I am the master of this mansion, Jin Sang-gun."
My gaze lingered on Leona’s face.
Gaia, standing behind me, licked her lips with a red tongue and whispered quietly into my ear.
"Master. That Princess bitch, the color of her soul is completely different from the humans of this world. She’s just a Princess on the outside, but there’s a strange soul stuffed inside."
I chuckled and stared straight at Leona.
"Princess. It is common sense that any woman who sets foot in this mansion must confess everything honestly, without hiding a thing."
Vwooooom----!!
A familiar violet wave forcibly tore through Leona’s soul.
The Princess’s golden eyes went vacant in an instant, and regardless of her own will, her lips parted on their own, beginning to spill the truth as if she were screaming.
"I, I am a transmigrator who lived in South Korea and came to this other world...! This place is the world inside the web novel I read!!"
"Ho, a world inside a novel?"
"According to the original story...! In the future, the protagonist bastard calls the Empire’s greatest beauties into this mansion one by one, strips them naked, puts heart patches on their crotches, and turns them into slave bitches who beg for his semen for the rest of their lives!! I didn't want that to happen, so I volunteered for the Hero party to run awayyy!!"
Leona had perfectly spilled her own massive secret and even the future of the original work with her own mouth.
"Ha, ha-up...! Wh, what did I just say...?!"
Leona, having regained her senses, was startled and hurriedly covered her mouth with both hands, but it was already too late. Her face had turned deathly pale, drained of all color.
"A very interesting future, Princess. So, it seems you want to follow the novel?"
I curled my lips into a wicked smile and snapped my fingers.
At that moment, my absolute power deeply carved a new 'common sense' into Leona’s soul.
It is common sense that for a transmigrator to survive in this mansion, they must perfectly perform all of the Master's rules (naked heart patches) to avoid the 'Transmigrator-Exclusive Extinction Penalty'.
Vwooooom----!!
As the violet wave swept through her brain, Leona’s eyes clouded for a moment before beginning to shine with a bizarre 'realization'.
'...Ah! That's right, what was I thinking!'
Leona slapped her knee hard in her mind.
'In a 19+ dark transmigration novel, isn't it a golden rule that if you don't cater to the protagonist, you get hit with a soul extinction penalty by the world system?! How could I have forgotten that and tried to resist!'
It was perfect mental pollution.
Leona, never dreaming that she had been brainwashed, fell into cognitive dissonance, believing she had to perform her 'survival quest as a transmigrator'.
'I have to live. This isn't being brainwashed; it's securing the minimum probability for survival!'
I tossed a large bundle of pink heart patches onto the table.
"It's a future you spoke of yourself, isn't it? If you want to live, take off your clothes right now and put those on."
"...Ha, ha-uk."
Leona gasped for air and began to unzip her flamboyant imperial gown.
Slide, thud.
The expensive silk dress fell to the floor, revealing the snow-white naked body of the Princess who had been raised as the most precious treasure in the Empire.
Her voluptuous breasts and slender pelvic line shone brilliantly under the living room lights.
"Wow! The Princess is finally changing into comfortable indoor wear! Good thinking!"
Aria, my childhood friend, who was shaking her pelvis while naked, clapped brightly.
Even as Leona flushed red with shame, she desperately activated self-rationalization in her mind.
'Yes... I have no choice if I want to avoid the system penalty. This is a quest. It's an unavoidable sacrifice for survival...!'
Slap! Slap!
Leona picked up the pink heart patches with trembling hands and slapped them onto her stiffened nipples.
Squish, slap!
And she pressed the patches onto the secret, untouched crevice of her maidenhood, making a lewd sound as they adhered.

"Ha, ha... Ma, Master... I have... worn them perfectly... according to the rules..."
The Princess, still believing herself to be a 'clever transmigrator using her head', crawled toward my stiffened center. Looking down at that pitiful head, I couldn't hold back and burst into wicked laughter.
"Good. The first stage is passed. But now that you're wearing new clothes, we should do a performance test, right?"
"...Performance, test?"
As Leona opened her eyes wide, I tilted my head and pointed at Gaia and Aria.
"Yeah. Stand between those seniors over there and shake your pelvis the same way. We need to check if the patches fall off even if you sweat."
At that moment, the polluted common sense in Leona’s brain flashed once more.
'...Ah! As expected of a 19+ novel, these perverted hidden quests keep popping up one after another! If I refuse here, the extinction penalty will surely stack. I must perform perfectly to live...!'
Leona rationalized this shameful situation as a 'genius survival strategy' and stood up.
Then, while wearing nothing but heart patches on her naked body, she slid in between Gaia, the supreme deity of the universe, and the Hero Aria, who were shaking their pelvises like crazy.
"Wow! Is the Princess dancing with us too? How exciting!"
Aria laughed brightly and bounced her pelvis even more violently.
Jiggle! Jiggle! Splat! Splat!
Gaia’s massive breasts, Aria’s resilient chest, and the white, noble breasts of Leona, the Empire’s greatest beauty, all mingled in the air and began to jiggle mercilessly.
"Ucha! Ucha! Princess, try shaking harder too!"
"Ha, ha-ang...! Ma, Master...! The newbie Princess is shaking it pretty well toooo...!"
Encouraged by the two senior bitches, Leona also flushed her entire body red and began to bounce her hips back and forth in a vulgar manner.
Squish, slap! Squish, slap!
The pink heart patches on the three women's breasts and nipples made intense friction sounds as they fluctuated.
'Heu-ang...! I feel like I'm going to die of shame...! But if I shake this hard... the hidden reward will drastically increase my survival probability...! I can survive...!'
"Hoo, hoo...! Ha...!"
Leona, who had been shaking her pelvis violently while fluctuating the heart patches on her breasts and crotch, finally stopped.
Even while her entire body was glistening with sweat and nectar, her golden eyes were burning with a tenacity for survival.
'I did it...! I finished perfectly! With this level of synchronization, it’s at a level where I might even get a hidden reward instead of an extinction penalty!'
Watching the Princess, who was gasping for air and glancing at me, I tapped my center, which was standing stiffly between my pants zipper, and muttered in a low voice.
"First hidden quest complete. Excellent, Princess. Now, shall we collect the reward?"
Simultaneously with my declaration, the polluted common sense in Leona’s brain brought up a fake system notification window as if it had been waiting.
[Notification: Hidden Quest Completion Reward 'Protagonist's Essence' has been activated.]
[※ Warning: If you refuse to accept the reward or fail to absorb it completely, the 'Soul Extinction Penalty' will be executed immediately due to the collapse of the world's probability.]
Leona’s face was filled with horror as she saw the transparent fake notification window.
'Insane...! Receiving the protagonist bastard's semen is a survival requirement?! If I refuse, I get extinguished?!'
Leona’s lips trembled in despair, but soon she exerted the cold reason (?) characteristic of a modern person and began to analyze the situation coolly.
'...Ha, yes. It’s a 19+ dark novel anyway. If I can secure a survival buff by sucking his cock a little at the beginning, it might actually be a gain. This isn't being brainwashed; I'm just a game efficiency-maxer running a smart macro!'
Perfect cognitive dissonance. She was the perfect completion of training.
"...I will gladly accept the reward."
Leona, even while tearing up, crawled between my thighs as if she had no choice if she wanted to live.
The Princess, known as the most noble in the Empire, was kneeling at my feet wearing nothing but heart patches.
Slide.
Leona carefully wrapped her trembling hands around my massive pillar. Facing my center, with its veins bulging ferociously, her salivary glands exploded instinctively, and saliva pooled at the corners of her mouth.
'I have to live...! I have to hit 100% absorption to fix my survival probability...!'
She stuck out her long red tongue and greedily licked the tip of my glans.
"Hup, eugu-uuup...! Uup...!"
Soon, she opened her lips as wide as possible and began to push my thick penis deep into her throat.
Even though it must have been her first time serving a cock, the sight of her rolling her tongue and desperately sucking with the sole tenacity of receiving a survival buff was truly vulgar beyond words.

"Wow, the Princess is really good at eating it even though it's her first time! Auntie Gaia, you'd better be nervous!"
Aria clapped naked from the side and giggled, and Gaia also smiled contentedly, gently massaging my pelvis.
"Heu-eung... Master, are you satisfied with the throat cleaning from the newbie Princess...?"
"Yeah. It's very excellent. The performance is certain."
The pitiful transmigrator Princess, who mistakenly believed she was using her head to turn the tables on the original protagonist.
While she was swallowing my cock to the back of her throat, looking up at me with teary eyes, I grabbed her blonde hair roughly and burst into laughter that shook the mansion.
