Waves of the Incubus - Chapter 18

 Two People

"Who is it?" 

"Who could it be?"

Both froze, startled, but naturally neither had any idea who had arrived. Kenichi, who had no friends or relatives coming to mind, even wondered for a moment if it was the police coming—a continuation of their joke from earlier.

In times like this, it would be convenient if he could use that powerful radar-like "power" he had at school. For reasons unknown, however, it was almost useless away from the school grounds. Though a black surge of energy could emit from his body, at home its range was 50 centimeters at most. At such a distance, verifying things with his eyes and ears was far more efficient and reliable.

"Wait here..."

He whispered to Natsuki, and sensing something in Kenichi's demeanor, she obediently nodded without a word. Leaving the bedroom, he shut the door tightly, tidied away Natsuki's athletic shoes lying in the entryway into the shoe cabinet, and opened the front door.

"Wh-What..."

Standing there was a girl in a tracksuit with a large bag, just like Natsuki.

The second unexpected visitor of the day was someone he could have deduced if he had thought about it logically; there was only one possible answer.

"G-Good evening..." 

"...Y-Yeah..."

It was Aiko Kawashima, a second-year member of the tennis club whom he had parted with at the station just an hour ago, fresh off winning the girls' singles tournament today.

Aiko and Kenichi moved to the kitchen.

Aiko had raised her face briefly when they first met at the entrance, but since then she had kept her head down with a flushed face. While she had hesitantly stepped into the room, she remained silent, leaving Kenichi unsure of what to do.

"Ah, um... Anyway, good job today... Congratulations on winning..." 

"...T-Thank you very much..."

Silence descended again. Facing the quiet Aiko, Kenichi didn't know how to handle the situation. Away from school, he reverted to his former self—timid and timidly soft-spoken.

"Why did you come here?"

Realizing this was the second time today he had asked this question, he spoke to the blushing Aiko. After standing still for a moment, she lifted her head and began to speak as if she had made up her mind.

"I-I've been feeling strange all this time... Ever since that thing happened with you in that room, Sensei... Every time I see your face, my heart throbs..." 

"..."

"And... even today... every time I looked at you, I felt so unsettled inside... I knew I shouldn't, but I couldn't help it... So, that's why... um... well..."

Having said that much, poor Aiko blushed down to her ears at the embarrassment of her own words and lowered her head once more.

Every time she locked eyes with her science teacher, an intense, burning urge welled up within her—an abnormal state occurring in her body. That very sensation was the cause of her throbbing heart and inner turmoil.

However, putting that reality into words made it sound like a confession of love. That realization drove her into a state of embarrassment so intense she wanted to disappear.

That wasn't all. Though she could never admit it to her science teacher if it killed her, lately she had been having explicit, erotic dreams every single night. What's more, the contents were so lustful and greedy that they would make adult videos look mild.

Taking advantage of the fact that it was a dream, she had sex with her science teacher every night, indulging in pleasure in various positions. Just last night, while wearing her school uniform, she got on all fours, spread her buttocks apart with both hands to expose her flesh, and begged for intercourse herself.

Every morning upon waking, the 17-year-old maiden sat dazed on her bed at the sheer wretchedness of her actions. In her dreams, she took the burly erection of the man before her into her mouth, shook her head, and grinned happily as she swallowed the large quantity of semen he released.

They say dreams are a mirror reflecting a person's hidden desires. For Aiko, the shock of discovering how lustful and greedy her true self was ran deep.

Aiko remained silent, looking down.

Kenichi, possessing remarkably little experience with women, had no idea what to say in a situation like this. If this were an erotic game, dialogue options would pop up, but naturally, no options appeared in real life.

Just as he was wondering what to do, an angel of salvation—or rather, a demon—emerged from the bedroom.

"Heeek!"

Shocked by the sudden appearance of a girl in a cheerleader uniform where she thought only two people were present, Aiko gasped upon recognizing her classmate's face and name. What's more, she had just made her embarrassing confession, which might have been overheard.

"You're... Kawashima-san, the tennis club captain... right?" 

"Y-Yes... You are Kurosawa-san from Class 4..."

Since they had been in different classes since entering school, the two had never spoken properly, but they knew each other by face and name. Above all, both possessed striking beauty that stood out whether they wanted to or not, and each was the ace of her respective club.

"I heard what you said in the back..." 

"...Th-That's horrible...!" 

"What are you talking about? You started talking on your own!" 

"...Th-That's true, but..."

While the two conversed as if hurling invisible sparks at each other in midair, Kenichi stood by listening quietly. However, he only appeared calm on the outside; internally, he was flustered, having no clue how to manage the situation. After all, the chemical reactions of a girl's heart were nowhere to be found in textbooks or study guides.

"Come over here for a sec. Grab that bag..." 

"...E-Eh? Why...?" 

"Just come... I'll teach you how to resolve this..." 

"W-Wait... Ahhh... Okay, I get it, I get it..."

Thus, Natsuki pulled Aiko by the hand and retreated back into the inner bedroom. Left alone in the kitchen, the timid teacher could only hover anxiously. Having nothing else to do, he took a sip of his lukewarm low-malt beer.

"Sensei! Come over here!"

After a commotion of arguing and scrambling inside, Natsuki called out to Kenichi from the bedroom once more.

Opening the bedroom door, an even greater shock awaited Kenichi than before.

"Tadaaa~ How is it? Two high school girls looking naughty?"

On the bed, two beautiful high school girls sat in their respective uniforms, waiting for Kenichi with their legs spread wide in an M-shape posture. Natsuki smiled brightly yet seductively as before, while Aiko was so flushed red that Kenichi felt sorry for her, looking off to the side while desperately spreading her legs to display her crotch.

"Ah... no... this is so embarrassing..."

Even though he had seen her in her tennis uniform plenty of times at the court today, seeing her in such an obscene posture from this close range carried an entirely different level of destructive force.

The white tennis skirt was pulled all the way up, leaving the crotch area covered by her pristine white undershorts completely visible. Adorned with cute lace ruffles at the rear, it was slightly smudged with dirt from the clay court.

"Come on, come on... Let's pick up where we left off, Sensei... You wanted to smell a high school girl's crotch, didn't you?"

Just like Natsuki, Aiko had been exercising all day today, so her entire body was drenched in sweat. Having come straight here after the tournament, she hadn't had the time or luxury to take a shower. Thus, the sweet sweat and body odor exhaled by the maidens rose thickly from their bodies, filling the small six-tatami bedroom in an instant.

"Come on... No need to hold back, Sensei! Kawashima-san is just like me—in the end, she just wanted to have sex with you too." 

"...Lies! Th-That's not true!!" 

"There's no other explanation... If you're panting every time you look at Sensei's face, what else could it be?!" 

"...Ahhh... I don't know... Could that really be it...?"

(Your overbearing logic and problem-solving skills are as powerful as a certain robotic cat from the future...) Kenichi almost blurted out.

"Come on... Don't just stand there, come over here, Sensei~"

Growing impatient as Kenichi stood dazed without reacting, Natsuki reached out and pulled him toward the bed.

"...Whoa, hey!" 

"Kyaah!"

Pulled suddenly, Kenichi tripped over a large bag at his feet and collapsed onto the bed. Since Aiko was right there with her legs spread in an M-shape, he desperately extended his hands to catch himself on the bed to protect her.

"...A-Are you alright...?" 

"Y-Yes..."

Saying so, his eyes met Aiko's beneath him, and her large dark eyes immediately grew moist. The healthy, sun-kissed beauty who looked so good in her white tennis gear hesitated for a brief moment before clinging onto the fallen Kenichi.

"Ahhh... Sensei! Sensei!"

Clinging desperately to his neck, Aiko began kissing him passionately, as if her previous shyness had been a lie. Her urgent, unreserved actions spoke volumes about the magnitude of the sexual desire she had been bottling up until now.

"Mmm... Fuuu-mmu..."

Covering Kenichi as he lay on his back, she proactively intertwined her tongue with his. With the same greed as when he first used the red tentacles, she licked around the inside of her science teacher's mouth as if his saliva were a sweet dessert.

"Nnn-fuu... Ngggh... Nnn..."

Because Aiko was on top facing downward, smooth saliva dripped down from her mouth due to gravity. The 17-year-old girl's fluid tasted as sweet as if mixed with syrup, and Kenichi swallowed it eagerly.

"Ahhh... Kawashima-san, that's unfair! I want to... I want to kiss Sensei too..."

This time, Natsuki brought her face close from the opposite side of Aiko—that is, from the left side of Kenichi lying on his back—and forcibly turned his face toward her to steal his lips. Twisted with enough force and speed to cause whiplash, Kenichi almost fainted from the intense pain as another beautiful girl sucked his tongue.

In an instant, squeezed between two beautiful high school sophomores, the science teacher lay between them, exchanging kisses alternately as they whimpered and begged from both sides. As he did so, dark red blood began coursing into his erection, causing the erectile tissue to swell rapidly.

Accompanying this, a black surge of energy activated, expanding outward with his body at the center. At home, its range was 50 cm at most, but that was more than enough distance for the two high school girls pressed tightly against him.

(It's here!!)

With a tingling sensation, evil red tentacles of thought extended from his body, coiling around Aiko and Natsuki on either side.

"Ahhh-nnn!" 

"Mmm-ffuuu-nnn!"

Aiko let out a sharp cry of pleasure with her open mouth, while Natsuki uttered a muffled scream deep in her throat, which was blocked by the kiss. The pink aura surrounding the two rapidly turned red, pulsating as its color shifted into an intense, vivid hue. Through his perception heightened by the wave energy, he could clearly confirm that both were in a state of intense arousal.

As always, the power of the red tentacles was staggering.

To the extent that she had been inexperienced and shy, Aiko's transformation was particularly dramatic. Like a butterfly emerging from a chrysalis, the ordinary high school girl transformed in an instant into a lustful, seductive imp.

"Hey, Sensei... First, Kawashima-san and I will lick you all over..." 

"Kurosawa-san and I will make you feel super good..."

The two beautiful girls, who stood out exceptionally at school for their looks, spoke in unison as they began stripping Kenichi's clothes off. With expressions melted by desire, breathing hot gasps, they excitedly stripped the teacher naked on the bed.

"Hey, hold on... I just got back earlier, so I'm dirty." 

"What are you talking about...? You made me lick you endlessly in my dreams..." 

"Huh?! Kurosawa-san, have you had dreams about having sex with Sensei too?" 

"Yeah. Don't tell me you have too, Kawashima-san? Lately, it's every single night~" 

"Yes, exactly! Me too, me too! Having sex with Sensei in my dreams every night has become normal now..."

Listening to their conversation, Kenichi thought with a hazy mind.

The incubus was originally referred to as a dream demon. As the name suggests, they were said to mate with target women in dreams, stealing their energy and sometimes making them bear demonic children.

On the other hand, the erotic dreams he had been experiencing recently felt vivid and real in his hands, with clear memories remaining even after waking up—completely different from ordinary dreams.

What if that dream world wasn't a simple dream, but a realm created by the incubus he contracted with? And what if Natsuki's and Aiko's dream worlds were connected by the incubus's power, sharing that world with him?

And what if the inccubus itself was an inhabitant of that dream world, able to move freely into other people's dreams through it?

"Ouch!!"

His train of thought was abruptly interrupted by a sharp sting.

"If you're thinking about other girls, I'm gonna bite you!"

Natsuki had bitten Kenichi's neck with her signature canine teeth as she spoke. Of course, the bite wasn't hard enough to draw blood.

"I'll turn into Dracula and drink your blood, Sensei..."

Cute as she smiled and said that, she trailed her tongue around the bitten spot and sucked up with her lips. As she made slurping sounds, the area bruised into a vivid hickey. Since he had no partner to worry about being seen by, Kenichi let the girl have her way.

"Oh no... Don't zone out, Sensei, feel good..."

On the other side, Aiko took her position on his bare upper body, licking his nipples over and over. Having done this countlessly in her dreams, her technique was practiced even though it was her first time doing it in reality.

As they did so, both were likely excited. Still wearing their cheerleader and tennis uniforms, they wiggled their high-raised hips covered only by miniskirts from side to side. That scene was reflected in the huge mirror of the dresser placed at the edge of the bed, clearly visible to Kenichi, whose eyesight had grown remarkably keen.

He felt like praising himself for placing the dresser in such a spot.

Natsuki's blue undershorts and Aiko's white undershorts were, as expected, wet and discolored in a narrow vertical strip from the honey overflowing from within. Even now, the red tentacles wriggled gently, continuously stoking their excitement.
