Waves of the Incubus - Chapter 36

 Women's Restroom

(...Is this... a demon's wave?)

The figure abruptly stopped walking and looked up at the sky, as if confirming something. The middle-aged man walking directly behind him wore a brief look of annoyance at the sudden stop, but quickly hurried past him.

Around them, many people were bustling about with busy and cheerful expressions, looking completely ordinary. It was the usual hustle and bustle of Shinjuku—a scene of a bustling commercial district found anywhere, symbolizing a peaceful Japan.

Yet that figure briefly sensed that faint yet distinct black energy, scanning the surrounding faces to identify its source. Suddenly, his eyes fixed on a towering luxury hotel, and he stared intently at it.

(Tch! ...Inside a hotel...)

Pinpointing the exact source of the malicious wave, he simultaneously wore a bitter expression. Since there were hundreds of people inside the hotel, it was difficult to determine precisely who was emitting the wave.

Normally, he would march right into the hotel and search until he found the person fused with the demon, but unfortunately, he had a prior engagement today.

He was scheduled to ambush and eliminate the target he had been tracking today alongside his allies. If he missed today, he would have to wait many days over again, so he could not afford to split up and act alone if he wanted to ensure the target did not escape.

"Evil thoughts are overflowing more than usual today..."

Looking up at the night sky covered in black clouds, he muttered aloud.

Though invisible to ordinary people, he could clearly see the swirling energy of evil thoughts in this metropolis flowing as dark streams. Cities like Shinjuku and Ikebukuro, where many people consumed by greed gathered, easily accumulated such thoughts.

Those thoughts served as nourishment for non-material energy life forms known as demons, drawing them to this society and serving as the catalyst to fuse with humans.

After standing quietly for a while, he could no longer perceive that black wave.

(My imagination? ...No, it was definitely a demon's wave. Still, with thoughts this strong, it's hard to distinguish...)

The strength of the wave he had sensed for a brief moment was faint, and even if it were a demon, it was likely of the lowest rank. If so, it posed almost no real harm to society, so it could probably wait. After all, the opponent he was heading to meet now was a middle-class demon who had appeared in this area after a long absence, and was a presence that had already claimed numerous victims.

(Well, I'll find and eliminate it eventually...)

Autumn had deepened, and the wind blowing between the buildings carried a slight chill. Glaring at the hotel, the figure turned up the collar of his thin coat and finally began walking again.

Vice Principal Usami had finally been discharged from the hospital and returned to school.

Naturally, his leg was still encased in a cast and he relied on crutches. With Usami's return—following surgery and hospitalization after tearing his Achilles tendon during a tennis match against science teacher Kenichi Mido—even the morning assembly had returned to its usual brisk routine.

When they exchanged morning greetings, Usami directed a look of intense, naked hatred, but Kenichi brushed it off with a completely ordinary expression. Back when he was timid and weak, he probably would have cowered at such a look, but now he appeared brazen and completely unconcerned.

Seeing Kenichi's attitude, Usami's hatred only swelled further.

After all, he had been defeated in his specialty of tennis and sent to the hospital, so the humiliation was beyond ordinary. Throughout his hospitalization, he had harbored a growing grudge, vowing in his heart to exact revenge someday.

Yet the science teacher who was the target of his grievances listened to the morning assembly looking thoroughly bored, as if to say the vice principal's thoughts meant nothing to him.

Neither Vice Principal Usami nor any teacher in the staff room, however, realized the truth.

Even at that very moment, black waves were emanating from the science teacher's body, enveloping the entire school and completely wrapping it within. Everyone inside had all their actions and states fully monitored, and within this ideal hunting ground of a girls' academy, an evil, lustful beast was keenly eyeing its next prey.

"No... Sensei, stop..."

The twenty-minute long break between the second and third periods. Summoned in advance via email, third-year student Ruriko Asakura was pinned against the wall in a private stall of the fifth-floor women's restroom, having her shameful parts licked from behind by the perverted teacher.

"What are you saying, Ruriko? It's already soaked down here."

"...Ahhh... No... It's embarrassing..."

Just as Kenichi pointed out, the refined and pure school idol known as "Madam Butterfly of Eris" was overflowing with a massive volume of nectar from her intimate parts, turning her light blue panties completely drenched.

Attending school in an ultra-miniskirt, Ruriko had fueled her perverted fetishes with the thrill of potentially being watched, and having been summoned via email since morning, she had become aroused in no time at all.

Violated all night long alongside Aiko and the others at the hotel the other day, Ruriko had her semen repeatedly discharged deep inside her womb, causing her body to mature rapidly through that magical power. Stripped of the greedy desires hidden beneath her refined and pure mask, she whimpered in embarrassment while actively seeking out the pleasure, devouring it repeatedly of her own accord.

Even while Natsuki, Aiko, and Tomomi lay exhausted, the greedy Ruriko had continued connecting with the incubus and voicing cries of joy. Seeing her wrap her black-socked legs around the dark-skinned man's body and kiss him dreamily, like a devoted married couple, would surely cause many students who admired her to drop their jaws in shock.

"Ahhhhh... In a place like this... If someone comes..."

Almost nobody ever came to the fifth floor, which housed special classrooms, yet someone might still wander in by chance. Despite the dangerous location, she felt a tingling, thrilling excitement because of it.

For Kenichi, of course, being discovered was an impossibility. His waves accurately informed him of the surrounding situation, allowing him to know precisely where everyone was as if looking at a map.

Yet Ruriko, unaware of Kenichi's "power," felt her head spin with the terror and thrill of not knowing when someone might walk in.

"Here, stick your hips out further."

"...Ahhh..."

When commanded, her mind went blank and she could no longer think, obediently thrusting out her shapely hips. The abnormal situation of mating with a man inside a cramped restroom stall ignited black desires from the depths of her body.

After a brief pause, she was thrust upward with a jarring impact.

"Hiiiiiii! I'm cumming, cuuuuuuming!!"

Standing and being penetrated from behind in the restroom, she was lifted by the long, massive penis along with her internal organs. Swept away in an instant by rough waves of ecstasy, Ruriko opened and closed her mouth like an oxygen-deprived goldfish, voicing cries of pleasure.

She must have taken a shower before coming to school this morning. From her long, glossy black hair, an indescribably lovely fragrance drifted. While ravaging her narrow interior with the massive penis from behind, he buried his face in her hair and became intoxicated by her aroma.

"No... Don't... Don't leave a mark!!"

As he held the third-year high school girl's body in her school uniform from behind and violated her from the hips while sucking on the nape of her neck, a dark red mark was left on her white skin.

"What if everyone finds out when you go back to class? That you were just having sex."

"No, no, no! If they find out, I'm ruined!"

Yet, ironically, imagining that exact scenario excited Ruriko so much that it surprised even herself, quickly driving her toward a second climax. Imagining herself returning to class with the lingering traces of sex on her neck and reeking of semen, her brain was struck with a blinding wave of excitement.

The hot, ecstatic impulse surged once more from deep within her body.

"Hiu!"

At that moment, a large teacher's hand reached out from behind to cover her mouth, and simultaneously, someone entered the restroom. Apparently, the restrooms on the lower floor were full, and two underclassmen had come all the way up here.

"Don't make a sound."

Ordered thus right by her ear, Ruriko nodded desperately, murmuring agreements. If by any chance she were discovered, it would spell the ruin of her social standing, so she desperately suppressed the screams trying to escape her throat.

Yet, ironically, precisely because of this situation, her excitement flared up even more. Her sphincter muscles contracted tightly, turning her already narrow vaginal interior into something unimaginably tight.

(Ahhh! No, no! It feels too good! I'm going to make a sound!)

The harder she tried to suppress it, the more her sexual sensitivity intensified. Without the large hand covering her mouth, she surely would have let out loud moans.

Before long, the sound of running water echoed as both of them finished using the facilities and left the stall. Hearing the sound of handwashing at the sink, Ruriko remained frozen in the innermost stall, letting out a sigh of relief.

"Hey, hey. By the way, did you see Ruriko-senpai today?"

Hearing her own name suddenly mentioned, Ruriko gave a start. At that jolt, the erection deep inside her womb rubbed against the vaginal wall, sending a forgotten, dull, sweet sensation rushing through her entire body. She nearly cried out in surprise and hurriedly bit down hard on her lips to endure it.

"Saw her, saw her! She had a different vibe today, didn't she?"

"I know, right? She's always been mature, but today she looked more like an adult woman..."

"Not to mention that miniskirt! I'd never wear a super miniskirt like that, even Ruriko-senpai."

"True. Even I couldn't pull off a skirt that short. Wonder if something happened with the senior?"

Apparently, they were chatting while checking their appearances in front of the mirror.

(I don't care... Just hurry up and leave...)

Ruriko screamed internally, feeling irritated by the two underclassmen whose faces and names she didn't know, while still being violated in a standing position.

Yet, as if ignoring Ruriko's plea, the two continued their idle, trivial chatter.

Behind her, Kenichi slowly began to move once more.

"Mufuuuuuu..."

Uttering a muffled scream at the intensely vivid stimulation, she glanced back over her shoulder, shaking her head in desperate, frantic refusal. The thought that they might be heard by the two still standing in front of the mirror made her heart shrink with a terror that caused her entire body to tremble.

(Stop! Sensei! Please, don't move!!)

Yet, as if mocking Ruriko's plea, the insidious teacher skillfully used his long, massive erection to stimulate her internal weak points. The lustful beast, already knowing every sensitive spot of this young lady inside and out, used his protruding flesh ridges to grind against those areas repeatedly.

"Kufuu!"

A small explosion of sound escaped through the gaps of his hand. She flinched, but it was already too late.

"Did you say something?"

"Nope... Must have come from over there."

(Hick! Found out!!)

Hearing those voices, the two students headed toward their direction.

Ruriko stiffened her body with her heart pounding frantically. Ironically, that tension caused her vaginal muscles to contract even more, further amplifying the sweet pleasure rising from her lower back. As her hips lost strength and she felt close to collapsing, the merciless penis thrust counter-punches upward.

"Ahiii!"

This time, a short but distinct cry of pleasure escaped her. While she was already overwhelmed by the sensation of her sensitive mucosa being ground against, the terror of someone potentially discovering her state acted as a spice, instantly igniting Ruriko's sensuality.

Even though she hurriedly covered her own mouth, it was too late.

"Is everything alright?"

A hesitant voice called out from beyond the door. Having heard the previous sound, whoever was outside apparently thought someone inside was suffering or in trouble.

(Hiiii! She found us!!)

That must be what they meant when they said your heart freezes. At that exact moment, Ruriko felt her heart genuinely stop beating for a second.

(What do I do... What do I do... What do I do...)

Should she answer, or ignore them? Unable to decide, she panicked.

The person on the other side seemed to be probing the situation as well. Several seconds of dead silence followed. She panicked, terrified that the sound of her pounding heartbeat echoing loudly might be heard.

(Please... go away somewhere...)

Ruriko prayed desperately.

At that moment, the unthinkable happened.

The teacher behind her grabbed her hips firmly with both hands and slowly began a rhythmic thrusting motion.

".........!!!!"

Ruriko bit her lips until they bled, pressing her hands over her mouth to kill her voice. Staring with wide-open eyes at Kenichi—who was committing outrages behind her—she shook her head violently to plead for him to stop.

Yet the demon, taking sadistic pleasure in crushing Ruriko's wishes, grinned wickedly as he used his hips mercilessly yet skillfully. When he hooked his sturdy ridge onto her G-spot—her primary weakness—she fell deeper into a profound ecstasy, letting out hot juices from deep within her womb.

".........uph!! ...kuh!!!"

Ruriko writhed, desperately suppressing her voice.

Her flesh pot clamped onto the erection like a toothless carnivore, squeezing the steel-like mass with all its might. The gripping force was enough to leave bruises, representing the ultimate pleasure instrument every man dreams of.

The supreme delicacy provided by an 18-year-old beautiful girl.

"Fuuu..."

Savoring an intense constriction that would make an average man last barely ten seconds, the lustful beast let out a small groan from his open mouth. In a high-stakes situation dripping with thrill, the school idol was clearly aroused and excited to an abnormal degree.

"Hey? Are you alright? Are you in pain?"

The two outside still hadn't given up, and now they were even tapping lightly on the stall door. They assumed the person inside was suffering from some illness and wanted to help in any way they can.

"I'll go call a teacher!"

With that, the other student scurried out, opening the restroom door and heading into the hallway.

(Hiiiiiiiiii! What should I do... What should I do!!!)

It was a true crisis.

Since there was only one restroom door to begin with, if multiple people arrived, there would be no way to escape or explain this abnormal situation. If it became known that she was locked in a private stall of the fifth-floor women's restroom alone with a male teacher, Ruriko's position at this school would instantly collapse.

Yet Kenichi continued his rhythmic movements, timing them to enjoy Ruriko's confusion.

".........っ!!!!!!!!"

Ruriko shook her head desperately, begging him to stop. She could not afford to be discovered looking like this, of all things.

Yet his rhythmic hip movements systematically targeted the zones of pleasure inside Ruriko's womb, forcibly driving up her sensuality.

(Stop it! Please, I'm begging you, stop!!)

She pleaded desperately, but the stimulation only grew, elevating the voltage of pleasure. Having been repeatedly ejaculated inside countless times, Ruriko's immature sensitivities had fully blossomed, granting her the sensitive, rich receptivity of a mature young wife through the incubus's magic. When probed thoroughly and persistently with that robust, thick staff, how could she possibly resist the stimulus?

Her body, rather than her mind, took over everything, and soon pleasure dominated all else.

(I... I'm already done!! No more, noooooo!!)

Having endured and held back for so long, the backlash was colossal.

Faced with the premonition of an unprecedented tidal wave approaching, Ruriko felt darkness cloud her vision in despair. Once she experienced this, there was no way she could keep quiet.

"I'm going to release it."

Whispered right by her ear, she understood the meaning of those words and shuddered.

(No! Not that! Please, forgive me only for that!!!!)

If they saw her leaking white bodily fluids from her crotch, she would truly have no reason left to live.

Her desperate attempt to pull away and shake her hips to dislodge him proved to be the fatal blow.

The gigantic glans scraped directly against the ring of the uterine opening that had descended, craving the seed of passion. Extremely congested and sensitive to the extreme, it was like sticking a needle into a balloon inflated to its absolute limit, causing an instant explosion.

"Higuuuuuuuuuuuuuuuu!! Guuuuuuuuuuuuuu!!"

An explosive orgasm that felt as though her brain were boiling forced a beast-like roar from her throat. Unable to muffle it with her hand anymore, she trembled throughout her entire body, raising a loud, rapturous cry.

"Ooooouh!"

Savoring the delicious taste of the eighteen-year-old virgin vagina clamping down with desperate intensity, Kenichi exhaled foul breath as he unleashed all of his accumulated white, wicked semen deep inside her. The muscular tube, contracting wildly from end to end, wrapped around him from tip to base with fierce intensity, attempting to wring the male dry.

"Ahiiiiiiiiiiiiiii! Higuuuuuuuuuu!"

When the high-speed white bullets battered the deep door of her flesh ring, Ruriko shook her body further, wailing aloud. The orgasm, which she had thought was her limit, deepened even further, and every single cell in her body trembled with joy as she welcomed the semen into her entire being.

An overwhelming surge of pleasurable current rushed through her, causing Ruriko's overloaded brain to finally shut down, and she lost consciousness. She felt herself slowly sinking into a dark yet sweet abyss that foreshadowed her future.
