Waves of the Incubus - Chapter 4

Activation

Even while dragging through the morning science class, Kenichi kept thinking about the strange event that had happened to him. It wasn't that he no longer cared about Junko and the vice principal, but rather that too many strange things were happening at once, drawing his attention away.

His severe nearsightedness had cured itself overnight, and during the morning assembly, he had managed to overcome a crisis by blurting out something on the spot without even knowing what the agenda was. It wasn't a coincidence, nor could it be explained by science; he felt an eerie, mysterious presence. Of course, there was no baseline proof for this.

Furthermore, he noticed his body felt strangely hot. If he took his temperature, it would probably be over 38°C (100.4°F). Yet, his head, which had felt so heavy this morning, was now completely clear, and aside from his lingering gloomy mood, his body felt astonishingly light. He was naturally uncoordinated and terrible at sports, but right now, he felt like he could handle anything.

(Unconscious memory? A hallucination or delusion caused by a fever?)

As a man of science, he tried to explain what was happening to him with logical reasoning, but too many points simply didn't add up. Putting aside his quick response in the staff room, his nearsightedness vanishing overnight was impossible by the standards of modern science and medicine.

"Sensei, what happened to your glasses?"

After class ended, one of his students, Natsuki Kurosawa, called out to him. Even in this prestigious girls' school famous for its beautiful students, she was a standout beauty whom Kenichi had secretly taken notice of. Lively and popular, Natsuki's father was reportedly an executive at a major corporation. Like a typical modern high school girl, her checkered uniform skirt was extremely short, about 25 cm above her knees. He had often caught glimpses of her underwear on the stairs and used it as fantasy material.

(That's rare... for her to initiate a conversation with me...)

Unlike Usami, Kenichi had a gloomy, dark personality and was by no means popular with the female students. In fact, in the student popularity polls, he was constantly fighting to avoid dead last. Naturally, Usami was always at the top.

"Sensei, did you switch to contacts? Or did you get LASIK?"

As the beautiful girl persistently questioned him, he noticed for some reason that her face was flushed and slightly feverish. It made her look even more adorable than she usually did in the classroom.

"No, it's just..."

While bewildered by her unusual behavior, he wondered if this was also due to the "power" of the contract. A female student who usually ignored him like background noise was now talking to him with genuine, deep interest, not just out of boredom or to tease him.

(Huh?)

That's when he noticed something. Looking closely, a faint, aura-like glow was emanating from Natsuki's entire body. It was so faint that he had to focus to see it, but a pale yellow light enveloped her, radiating outward.

(What is this?)

"Sensei... you're making me blush... Don't stare at me so much..." Natsuki said, smiling bashfully as she assumed he was gazing at her passionately.

As she did, the wave-like aura around her shifted slightly in color, deepening before returning to normal. He quickly realized that the aura reflected her inner state. Even as he watched, the hue shifted subtly, though it remained mostly a pale yellow. However, he couldn't yet understand what the specific colors meant.

A science teacher and a beautiful student standing and talking in the hallway—it was a bizarre pairing that drew glances from the other students passing by. It was only natural, given the combination of the school's least popular, plain middle-aged teacher and a top-tier beauty.

Kenichi’s usual cowardice urged him to flee the scene immediately, but he suppressed the urge and checked the surrounding students. From what he could see, no such aura was visible around the others; for now, it was only coming from Natsuki.

(What on earth is this aura... Its color changes subtly along with her emotions...)

"Hey, Sensei... What are you zoning out for?"

Watching the aura, he realized something unbelievable: the beautiful girl in front of him actually held affection for him. Proving his theory, Natsuki, one of the prettiest girls in the sophomore year, seemed eager to keep talking to him despite her bashfulness.

(I want to know more about what this aura is...)

His scientific curiosity began to surge. But this was a bad place; they were already drawing too much attention.

"Ah, right... We have a 20-minute break right now. I need to prepare for a test. Kurosawa, could you come to the science prep room and help me out?" Kenichi spoke to Natsuki with a calmness that surprised even himself. The old Kenichi would have turned bright red and started stuttering.

Natsuki nodded happily and smiled at him. Immediately, the aura radiating from her body grew deeper in color.

Walking through the hallway where other students chatted and laughed in groups, Kenichi and Natsuki headed toward the science prep room. As they went up the stairs, the presence of other people thinned out. The distinct smell of school floor wax grew stronger, and the air on the fifth floor—the top floor—felt somewhat colder and more stagnant compared to the lower levels, as if the remnants of human presence had settled there.

"Sensei, you seem completely different from usual..."

"R-Really?"

"You seem kind of wild and manly. Maybe it's because you took off your glasses?"

Her eyes seemed somewhat moist as she looked at him. Being told such things by Natsuki, who could easily pass for a magazine cover model, certainly didn't make Kenichi feel bad.

"Alright, can you help me separate these printouts here?"

Entering the dimly lit science prep room, Kenichi walked over to a desk piled with printed papers and began sorting them into class sizes alongside Natsuki. Because this prep room was tucked away at the back of the fifth floor, barely anyone besides Kenichi ever approached it.

Isolated from the noise of the school in this dim room, the beautiful girl showed no signs of anxiety about being alone with the school's least popular male teacher. Under normal circumstances, let alone being alone with him, she would never have approached such a dark room willingly.

"Shibata-sensei apparently mixed up the classes the other day and gave our class the same quiz twice. Since we'd already done it, everyone got really good scores... Shibata-sensei looked so surprised..."

Natsuki kept talking cheerfully by herself, shifting from school topics to classes. While moving her hands at the desk, she kept up a continuous stream of casual chatter. A faint, wave-like yellow light still emanated from her body, showing up even more clearly in the dim room.

Every time Natsuki moved, the clean scent of a young girl wafted over, intoxicating Kenichi as he stood beside her. Watching her hips sway in her extremely short skirt, he felt a dark, heavy desire surging within his body.

(N-No, I shouldn't...)

It wasn't that he had never harbored foul thoughts before, but he had never felt such overt, intense desire for his own student inside the school. Yet, as if mocking his restraint, the desire inside him ballooned rapidly, and his manhood grew hard and swollen.

Then, an astonishing transformation occurred.

As his arousal peaked, his perception sharpened to a crystal-clear edge, and his five senses expanded infinitely.

(W-What is this?)

As his throbbing heat expanded, his senses became unnaturally acute, allowing him to perceive the entire space of the room around him perfectly. The airflow, Natsuki's breathing, the ticking of the clock's second hand—he grasped everything with terrifying accuracy.

At the same time, he felt a certain power radiating from within himself. The energy exiting his body rippled outward in all directions like waves on water. To Kenichi's eyes, it looked like dark waves, rising and falling in a slow, rhythmic pulse.

Naturally, this dark wave reached Natsuki, who was standing right next to him.

At that moment, a thin, red, translucent entity emerged slithering from his body.

(What is this?)

The red, translucent mass extended smoothly like a glowing tentacle, wrapping itself around Natsuki's body. Unlike the dark waves that spread randomly, this tentacle possessed clear intent, targeting the beautiful girl beside him.

As the red tentacle coiled around Natsuki's uniform-clad body, the color of the aura she emitted began to transform rapidly. It was as if the red tentacle's color blended into Natsuki's aura, changing hues in sync with the pulse of his desire. Gradually, her aura stained into a vivid red.

(What... What am I doing to her?)

When Kenichi focused his mind further on the changing aura, the red tentacle split into dozens of branches, coiling tightly around her entire body. From her feet to her thighs, her waist, her chest, her neck, and her head—the red tentacles bound the beautiful girl like a predator securing its prey.

Yet, Natsuki seemed completely oblivious to the tentacles wrapping around her body. Even while completely entangled, she showed no sign of noticing, continuing to chat happily just as before. It appeared these red tentacles were visible only to Kenichi.

For reasons he couldn't explain, his heart commanded him to make Natsuki's aura turn even redder. Following that urge, he focused his consciousness and willed it intensely.

"...Nnh..."

Instantly, Natsuki let out a small, hot sigh.

(Kurosawa...!?)

Simultaneously, through his hyper-sharpened senses, he accurately perceived the physical changes occurring in Natsuki's body. Her mouth parted slightly as she exhaled hot breath, and her cheeks flushed red all the way to her ears. While that much was visible from the outside, he could unbelievably sense that she was sexually aroused—her nipples hardening, her core becoming damp with moisture, and her anatomy swelling with arousal.

(Look at her... She's completely turned on.)

Seeing the beautiful girl suddenly become aroused right next to him, Kenichi felt his own excitement surge even higher. As his manhood throbbed, the tentacles became hyperactive, causing Natsuki to shiver visibly. It appeared the frequency of Kenichi's arousal was being transmitted through the tentacles, synchronizing directly with Natsuki.

By now, the aura enveloping Natsuki flickered rapidly through various shades. She seemed to be resisting something internally, but despite the shifting intensity, her aura was completely overrun by the red tentacles, bearing no resemblance to the yellow light from earlier.

Could this aura be showing Natsuki's physical and mental compliance?

(Let's test it out...)

Perhaps unable to concentrate, Natsuki had restarted counting the papers several times. Kenichi placed his hands on her shoulders.

Natsuki gave a violent start.

"Kurosawa..."

When he turned her to face him, her expression was undeniably that of an aroused woman—a look even Kenichi, with his lack of female experience, could easily recognize. At the same time, the wave of light emanating from her body had completely turned a deep, solid crimson.

He could see more tentacles emerging from his hands on her shoulders, winding tightly around her. Dozens of red, semi-transparent tentacles had now manifested from Kenichi's body, binding her without a single gap, completely visible to his newly cured eyes.

The beautiful girl stared at him with moist, damp eyes, but soon closed them, adopting an ecstatic expression. It was the exact expression he had seen countless times on actresses in TV dramas when they were waiting for a kiss.

(I-Is this really okay...)

Even though his heightened senses told him Natsuki was deeply aroused and desired him, his rational mind still struggled to believe the transformation. After all, there was no reason a woman should ever harbor desire or affection for someone like him.

Yet, Natsuki kept her eyes closed, waiting. Her plump, pink lips were slightly parted, looking unimaginably cute and desirable.

(To hell with it!)

Overcome by desire and pushing aside the sudden fear of being sued for sexual harassment, Kenichi couldn't resist the expression the beautiful girl was showing him. He brought his lips close to her soft mouth.

"Ah... Sensei... no..."

Contrary to her spoken words, the usually unapproachable beauty offered no resistance as she accepted his kiss. Kenichi savored the sensation with overwhelming emotion. The fact that he was kissing his own student in broad daylight inside the school sent the gloomy, timid science teacher into a state of pure ecstasy.

(T-This is incredible!!)

Trembling with a joy that made him want to dance, he pressed his lips against her soft mouth. After confirming she wasn't resisting, he parted her teeth and hungrily slid his thick tongue inside. To his amazement, the beautiful girl accepted his tongue ecstatically, letting him freely explore the hot inside of her mouth.

The incredible heat. The sheer sweetness and comfort.

(Ah... amazing... I'm actually kissing Kurosawa...)

Completely losing himself, Kenichi drank in Natsuki's sweet saliva, driving his aggressive tongue deeper into the pristine mouth of the beautiful girl.
