Prologue

Author: This will be my first time writing an erotic and sex story, so I'm sorry if it's not good.

Black... that was the only thing visible about the figure of many colors. No matter the direction, all that could be seen was the abyss staring back. An abyss so dark that even the very concept of darkness lost its meaning, as did direction and perception.

Until, amidst that abyss, another figure appeared. It was a humanoid form resembling a young woman, slightly taller than the average female, standing at 1.80 meters, with a voluptuous figure. Her body radiated a dazzling white light that made the abyss seem like a cave illuminated by a powerful flashlight.

"Where am I...?" the figure, seemingly falling endlessly into the abyss, asked herself. She only remembered reading the Medaka Box manga and enjoying the romance and development between Medaka and Zenkichi. After finishing the story, she had decided to take a nap around 4 a.m., sacrificing a few precious hours of sleep.

But now, she found herself in this place, falling indefinitely into the abyss. It felt like a fantasy playing out before her eyes. She couldn't deny her fear; after all, humans fear the unknown, and those afraid of the dark often fear what might be hiding within it.

Finally, the light of the humanoid figure reached the falling figure. Was she really falling, or did it just feel like she was plummeting? She couldn't answer that question. Eventually, the larger figure's light reached her "eyes.".

"Well, well... what do we have here? A small and insignificant soul that has escaped the cycle of reincarnation. Well, since this has only happened ten times, including you, we must grant you some 'compensation.'" The radiant figure spoke calmly, with a serenity that transcended human comprehension, beyond description by mere words or writing. It was like trying to record information about a transcendent being.

"Who are you?" the falling individual asked, dazed and confused by the radiant figure's words.

"Who am I? Well, that doesn't really matter. What matters is that you will reincarnate randomly into a world, along with the body of the protagonist from the last story you saw. Plus, you'll receive tickets." As the radiant figure spoke, it clapped its hands, and a roulette wheel with billions or even trillions of titles appeared. With a snap of its right fingers, the wheel began to spin.

Minutes or hours passed; it was impossible to tell. The concept of time did not exist here, so a three-dimensional being's understanding of time made no sense in this place. Eventually, the wheel slowed down and stopped on: High School DxD.

The soul panicked. Even though she had only heard about the series from friends who had read it, she knew this world was extremely dangerous! If you were strong, you'd be enslaved by demons or killed by fallen angels, and the darned church wouldn't do anything about it! There were dragon gods who crushed stars with ease, and characters who could destroy small planets. The more she thought about it, the more discouraged she became.

"Don't be so down. Look on the bright side—your body will at least be equivalent to a high-class demon. At best, you might even surpass Serafall, but... that's only considering raw power. In a fight, you'd still take a beating since Medaka can't surpass the speed of light. But don't worry! That limitation only exists because of Medaka Box's world rules. Here, you can." The radiant figure offered a small explanation to calm the trembling soul, which now shook a bit less.

"Alright... but what are these tickets?" The soul, now curious about the mention of tickets, attempted to stabilize herself and stand. However, this only left her more confused, as it was unlike stabilizing oneself in air or water—something beyond comprehension.

"Don't bother; you're like a drawing trying to comprehend a three-dimensional world. Anyway, to answer your question: since you weren't the best person in your life, you'll only get four tickets. One is to modify a power or ability from Medaka's body, and the others are for skills or powers: one EX-rank, one A-rank, and one D-rank. None of them can have offensive capabilities. By the way, a normal person would receive five tickets, but since you were a degenerate with strange fetishes, I deducted one ticket as compensation." Though invisible, the radiant figure's malicious smile and possible look of disdain were palpable.

"That's UNFAIR! YOU CAN'T JUDGE SOMEONE JUST BECAUSE OF THEIR TASTES!" The soul shouted, but the radiant figure nonchalantly cleaned its ear as if hearing an annoying high-pitched noise.

"Fair or not, I am the law, and I am the rules. You have no choice but to accept it. But as compensation, I'll add one of your peculiar tastes to your new body." The response was calm, spoken with a tone of disdain, as though the figure barely cared.

Sighing in resignation, the soul gave in. A stream of information about how to use the tickets flowed into her mind. She mentally wished for the panel to open, and it did. Quickly, she searched for passive evolution abilities. Thankfully, a search bar allowed her to narrow her options, but to her disappointment, she found nothing of that sort—it made sense since it would be too overpowered.

She finally made her choices, noticing that many of the abilities she'd considered weren't available, likely because they were too broken. However, she was surprised to see a Rank A skill of that nature. Afterward, she modified one of Medaka's body's abilities.

Another mental panel opened, and she was thrilled to see everything listed. Her excitement grew even more upon seeing her gender.

[Name: Medaka Kurokami

Sex: Female

Addition: Futanari

Race: Human]

『Personal Skills of the Body』

The End - Rank EX: Unlike the original Medaka's The End, which required her to be physically superior to copy a power and was limited to Abnormalities, this version allows the user to learn and perfect any skill or power.

Wound Erasure - Rank D: Capable of erasing severe injuries like a destroyed heart. However, decapitation or attacks beyond that scale will result in death.

『External Skills』

Presence Concealment - Rank EX: Completely erases all traces of existence, becoming one with the world.

Instant Comprehension - Rank A: Allows instant understanding of anything seen at least once.

Cleaning - Rank D: Removes all impurities (stains, dust, odors, etc.), leaving everything spotless and shiny. Even the tiniest impurity disappears.

When her consciousness returned, she found herself in a dark, lightless space, but through touch, she could perceive it was an extremely claustrophobic environment. Then, a metallic, emotionless sound echoed in the baby's mind.

[The being "■■■" has caused the host's consciousness to awaken at 8 months and 51 weeks. At this moment, you are about to be born. Your parents are already at the hospital.]

As the young baby absorbed this information, an immense pressure began to force itself upon her tiny body. After several minutes, she finally emerged into the world, feeling the midwife clean off the small amount of blood on her body before handing her to her mother. Initially, her beautiful mother was worried because the baby wasn't crying, but she soon felt relieved when she realized her child wasn't lifeless—she was simply gazing at her with curious eyes.

The hospital room door suddenly swung open, revealing a tall man with brown hair, tanned skin, and piercing red eyes. His build was strong, and he wore what resembled a black suit with a red tie. His commanding appearance might have made him seem intimidating, but the concern in his expression as he looked at his wife softened his aura. Even so, his crimson eyes retained a sense of intensity.

"Darling, let me hold our little princess so you can rest." His deep voice carried a gentle warmth as he extended his arms slowly. He carefully cradled the baby, wrapping her tiny body in his arms with a tender embrace. The warmth of his touch was unlike anything this child had ever known from a paternal figure. "Medaka, from this day forth, you shall be Medaka Kurokami, our daughter and rightful heir." His voice brimmed with affection, wrapping the child in a comforting cocoon.

As Medaka turned her gaze toward her mother, she saw an elegant woman whose beauty could easily rank among the world's most stunning. Her long purple hair was disheveled and drenched in sweat, her pale skin glistening from the effort she had exerted moments earlier to bring her baby into the world. Slowly, her eyelids drooped, hiding her lilac eyes. Her chest rose and fell gently, signaling she was drifting into much-needed rest.

Medaka's father began softly rocking her in his arms while humming a beautiful melody. His voice was so pure and soothing that, within seconds, both his wife and "precious treasure" were sound asleep. Moving silently, he approached his wife and placed the baby beside her on the bed. From his pocket, he pulled a small piece of paper with his left hand and a pen with his right. Writing a few comforting words, he assured her that she could call him if she needed anything.

With quiet steps, he left the hospital. Once outside and at some distance, he paused to glance back at the building, a warm smile adorning his face.

———————————————

After 16 years, I found myself standing behind the red brick gates, just one step away from entering high school. Currently, I am a 16-year-old freshman. Of course, I could have skipped a few grades if I wanted to, but I chose not to. This was Kuoh Academy.

At present, I am a slender young woman with very long purple hair that reaches my waist, bangs that barely cover my eyes, and an ahoge on top. My bust measured 98 cm, my waist 59 cm, and my hips 87 cm. In the entire Kuoh Academy, only Rias Gremory and Akeno Himejima surpassed me in measurements.

To be honest... these have been the best years of my life. I couldn't ask for anything better than loving parents, something I never had in my previous life. My "addiction" only began when I was 15 years old. I admit, the extreme sensitivity almost made me moan that day and nearly drew my parents' attention. But, thank God, I managed to hide it, which allowed me to keep everything under wraps.

When I was 7, my parents revealed the existence of the supernatural world to me. After seeing them suppress their magic to human levels just once, I learned to do the same. My parents called me a prodigy. They prioritized me more after seeing my talent—perhaps excessively so, but I didn't mind. From that day onward, I always wore a seal that restricted my mana to human levels, which, of course, also diminished some of my physical abilities. But that was fine since I used it as training. You could say I'm always operating at less than 15% of my full power.

Of course, you could say that Magic Power≠Physical Power, and you'd be right, but that doesn't apply to me. I discovered a method to enhance my physical attributes in exchange for magical energy.

In my past life, I was nothing more than an orphan. At 7, I was expelled from the orphanage because there were too many mouths to feed, and they discarded the least necessary and talented child. From that day on, I lived without a roof, without walls, without food—only with the loneliness inside me. I stole to survive, was beaten many times, and was almost assaulted once by a homeless man who had probably gotten drunk after obtaining some alcohol from a bar. But that's just a hypothesis.

Over time, however, I managed to rise above it all.

During this period, I've been fighting against the supernatural, subjugating stray demons. Of course, up until now, I've only fought one that approached high-class level. The closest to that was a mid-high-class male demon with a monstrous appearance, one of the strongest in the middle-class category. I was almost killed in that fight, and nearly assaulted, but thanks to my "Wound Erasure," I caught him off guard and managed to plunge my hand into his chest, crushing his heart with my fist.

Recalling this, I could only sigh heavily, blaming my pride for wanting to fight a demon head-on. Sure, I had defeated other mid-class demons without much trouble, but I hadn't expected that venom ability to make such a huge difference. That venom paralyzed muscles and confused the nervous system, spreading throughout the poorly lit warehouse. I couldn't dodge it, but thanks to that fight, I discovered that my Wound Erasure could even purge poison from my body.

Taking a deep breath and exhaling the air from my lungs, I stepped forward, entering Kuoh Academy. I felt several gazes directed at me, but I wasn't bothered. However, I did notice three lecherous stares. Recognizing who they were, I didn't even bother to look in their direction—I simply pretended they didn't exist.

———————————————

If Medaka had to define the things she studied, it would be "boring." She had only met with Sona a handful of times and had seen Rias just once, through the window of her clubroom that same day. However, Rias hadn't noticed her because she was using her Presence Concealment ability.

Medaka dropped her backpack in the corner of her queen-sized bed, which had a base made of refined white wood.

She sat there, quietly waiting for the "intruder" to enter her room. Since earlier that afternoon, she had intentionally allowed a certain supernatural being to sense her power. It wasn't low enough to go unnoticed, but it wasn't high enough to scare them off—it was just enough to draw them in.

It didn't take long for a tall, slender woman with long navy-blue hair and brown eyes to appear. She wore a brown cropped trench coat with a wide collar, a matching miniskirt, and black high-heeled shoes. The trench coat's top was open around her chest, offering a generous view of her cleavage. A gold necklace adorned her neck, and a white shirt seemed to be underneath her outfit, though it was only visible from certain angles. This was Kalawarna.

"I've been waiting for you, raven," Medaka teased, her voice sharp and precise. The provocative remark made Kalawarna respond immediately.

"You litt——" Kalawarna, who was about to protest, didn't get the chance, as Medaka's lips crashed onto hers and the young woman's left hand pulled the fallen angel down to her height. The fallen angel's eyes widened.

But for some reason, her body refused to obey her commands, and she found herself simply returning the kiss. However, due to her experience, she began to take control of the battle of tongues, even letting out a mental chuckle at her dominance. Medaka, who was now being overwhelmed, simply closed her eyes and let herself go. She knew, though, that this fallen angel wouldn't go too far—after all, one of Addition's abilities was "Aphrodisiac Saliva."

What Medaka didn't anticipate was how bold Kalawarna would become under the effects of her saliva. Suddenly, Kalawarna lifted Medaka slightly, gripping her rear firmly with both hands and sliding under her skirt. This action elicited a low moan from Medaka, muffled as their lips were still locked. Spurred on, Kalawarna began devouring her mouth, her tongue exploring every inch of the younger woman's mouth. When their kiss broke, a thin string of saliva connected their lips.

Taking advantage of her position, Medaka pushed Kalawarna against the wall and tore apart her brown top, revealing her full, voluptuous breasts. The shorter woman leaned in, taking part of Kalawarna's left breast into her mouth, while her left hand played with the other. Her tongue teased the fallen angel's nipple, making light suction motions that sent shivers through Kalawarna's body. Medaka was clearly skilled.

"You're quite bold, aren't you?" Kalawarna said with a husky voice as she tore open the upper part of Medaka's clothing and began teasing her nipples. This sudden action caused Medaka to freeze, her ability to toy with Kalawarna's breasts halted. It was the first time she had felt this kind of stimulation, and she was still processing the pleasure coursing through her.

Noticing Medaka's hesitation, Kalawarna pushed her onto the nearby queen-sized bed. In one swift motion, she removed Medaka's skirt and panties, revealing to the world a 21-centimeter-long penis.

Unintentionally, the fallen angel began to salivate at the sight, but she held herself back. Gripping the base of the shaft, she placed her thumb on the pink, mushroom-shaped tip. Slowly, she began to stroke—down, up, and down again. Little by little, pre-cum began to drip from the urethra.

"Aahh~" Medaka let out a soft moan as she felt the unfamiliar sensation of someone else stroking her. Due to one of the debuffs from "Addition," the delicate and gentle touch of Kalawarna's hand nearly made her climax immediately. Seeing this, Kalawarna smirked mischievously and increased the strength and speed of her strokes, causing Medaka's moans to grow louder with each motion.

Medaka's toes curled, and her breathing grew erratic as even her testicles were teased and played with like toys by Kalawarna, who had completely taken control of the situation. Finally, Medaka couldn't hold back any longer.

"AHHHHH!~~❤️" she cried out loudly as thick, sticky streams of white semen burst from her urethra. The warm fluid coated Kalawarna's hand, with some drops landing on her face and chest, while even the ceiling was marked with streaks of white. A few stray droplets fell back down onto the fallen angel, but Kalawarna didn't stop with just a simple handjob. She quickly enveloped Medaka's shaft and base with her soft breasts.

Despite Medaka's size, Kalawarna stretched out her tongue and began to lick and suck on the shaft while continuing to stroke the base with her breasts.

Lewd, wet sounds filled the room as Kalawarna's saliva dripped down, coating the entire length of Medaka's member and serving as lubrication for the fallen angel's relentless double assault.

"Aaaahhhhh!~~" This time, Medaka's moan was softer, but her legs trembled, and spasms of pleasure coursed through her body. The combined sensation of Kalawarna's warm mouth and her breasts, which squeezed her shaft like the inside of a vagina, sent waves of ecstasy through her.

"So soon? I thought you'd last a little longer~" Kalawarna teased, feeling Medaka's shaft throb and pulse wildly between her soft breasts. Realizing that the overly sensitive Medaka was about to climax again, she resumed her relentless assault. Within moments, another helpless moan escaped Medaka's lips, accompanied by spasms that shook her legs.

Glup! Glup! Glup! Pop!

Kalawarna greedily swallowed every drop of Medaka's seed, using her breasts—which squeezed tightly, mimicking the sensation of a snug vagina—to milk out as much as she could. Medaka could only let out weak moans, entirely at Kalawarna's mercy. Both of their minds were clouded in a haze of lust. The fallen angel consumed nearly a liter of the thick, creamy nectar. Its flavor, sweet with a hint of saltiness, was to her liking. 

Once satisfied, Kalawarna climbed atop Medaka and locked eyes with her. A playful smirk adorned her lips.

"Well, it seems you were acting a bit too cocky, weren't you?" she remarked, her tone dripping with amusement.

As she spoke, Kalawarna began stroking Medaka's momentarily soft member, coaxing it back to full hardness. The shaft quickly regained its impressive firmness, standing tall like unyielding steel. Kalawarna knelt over Medaka's erection, grinding the wet slit of her dripping entrance against the sensitive tip of Medaka's cock. The contact elicited another soft moan from the younger girl. 

Without warning, Kalawarna slammed herself down in one swift, powerful motion.

Smack!

The sound of her thighs colliding with Medaka's filled the room. Both women moaned together in a harmonious symphony of pleasure. Kalawarna began moving, her hips rolling faster and faster, the rhythmic sound of skin slapping against skin growing louder with each thrust.

Encouraged by the mounting pleasure, Medaka grabbed Kalawarna by the hips, matching her movements and increasing the speed. The fallen angel let out a deep moan, her pace growing erratic as they approached the peak of their pleasure. 

Finally, both of them reached their climax. Medaka let out a guttural cry as her thick, warm seed surged deep inside Kalawarna, filling her womb completely. Kalawarna's body trembled, her insides tightening around Medaka, ensuring every last drop was taken.

The Fallen Angel's eyes rolled back into her head and she collapsed onto the smaller girl's body, who was only gasping for breath. Medaka's member was still embedded in Kalawarna's pussy, but through the small gaps, semen was leaking out. Kalawarna, even with years of experience, had passed out. Maybe it was because Medaka's cock was much bigger than anything she had ever endured? Probably.

Medaka, still panting, her purple hair messy and sticking to her skin, found herself oddly enjoying the sensation of being dominated. Her thoughts were abruptly interrupted by the sound of a notification.

[Congratulations! You have met all the requirements to make Kalawarna your subordinate!]

[Y/N]

Exhausted, Medaka mentally clicked "Yes." She gently moved Kalawarna to the side of her bed and slowly withdrew her member from the fallen angel's pussy. As she pulled out her now-flaccid length, a small stream of white semen trickled from Kalawarna's relaxed entrance. Medaka was careful enough to remove herself so delicately that she didn't even disturb Kalawarna's peaceful sleep.

The scent of semen, however, lingered heavily in the room, making Medaka sigh in mild irritation. Using her "Cleaning" magic, she quickly rid the space of all odors and impurities.

Rising from the bed, Medaka cast a spell to hide her "Addition" once again. But as she finished, the system sent another notification:

[Since you've had your first sexual encounter, your "Addition" will no longer disappear. Good luck!]

She could almost imagine the system giving her a thumbs-up, telling her to figure out how to deal with this "monstrosity" herself.

With a resigned sigh, Medaka slipped into her pajamas, climbed back into her bed, and laid down next to Kalawarna. Their bodies rested mere centimeters apart, close but not touching.

Author: I want to apologize if my sex writing isn't good, after all, it was my first time. Medaka was easily dominated because she was extremely inexperienced and only had the theoretical part (from reading hentai).
