IS, formally known as Infinite Stratos.
In a world where male superiority has given way to female superiority due to the appearance of the world's strongest weapon, the IS, which only reacts to women, the protagonist, Orimura Ichika, happens to activate an IS despite being male and is forcibly enrolled in the IS Academy, an institution for training IS pilots.
Since "males cannot pilot IS," Ichika becomes "the only man in the world who can use an IS" at the all-female IS Academy. Amidst his academy life, various encounters, reunions, a difficult daily routine, and days of fighting over the IS begin.
◇◇◇◇◇◇◇◇◇◇◇◇◇◇◇
It was spring break after the graduation ceremony at First High. I had come to the world of Infinite Stratos. Unlike the DxD world last time, I have a complete grasp of this world, from the original novels and anime to the social games, so I know exactly which girls are here.
And who did I bring to this world this time?
"So this is the other world, huh? I'm excited!"
"Hey, Lina, don't talk about it out loud too much."
"Yes, yes!"
I brought Lina. The truth is, we can't do anything unless we can pilot an IS. Since the setting of the story is the IS Academy, it's better to have someone with IS aptitude. As a result of my selection, Lina possessed an IS aptitude of A-rank, the same level as the original heroines. By the way, I set my own aptitude to B-rank using my modification ability. There's also another reason why I chose Lina, but I'll get to that later.
◇◇◇◇◇◇◇◇◇◇◇◇◇◇◇
Thus, Lina and I successfully transferred mid-term into the IS Academy. You might ask why not from the start? This time, I decided to enter right after all the heroines from the first season of the anime had gathered, which is at the beginning of Volume 3 of the original novel. There are various reasons, but the simple fact that "I was too lazy to wait for all the heroines to gather" accounted for about 60% of it.
Now, the reaction from the main characters in Class 1-1, where they were, was intense regarding the unseasonal transfer students. Just one month prior, two heroines had transferred into Class 1-1. Since two more were transferring again, it would be stranger if they weren't surprised.
"Hey, can I talk to you for a minute?"
The first person to speak to us was the protagonist of this world, Orimura Ichika. He's a handsome, wooden-headed guy who goes through academy life completely oblivious to the affection of the five plus two heroines. He supposedly possesses enough sensitivity to react to the opposite sex, but I can't help but feel like saying "Is this guy a homo?" based on my past life experience.
"You're Tachibana Jun, right? I'm Orimura Ichika, call me Ichika. Nice to meet you, Jun."
"Yeah, nice to meet you."
In my mind, I thought, You're still calling me by my first name so casually, but outwardly, I shook the hand he offered so as not to cause trouble. Well, for now, I'll play nice.
Then, Ichika introduced the heroines in Class 1-1, and the heroines greeted me.
"I'm Shinonono Houki."
"I am Cecilia Alcott."
"I'm Charlotte Dunois, nice to meet you."
"I am Laura Bodewig."
"Oh, and there's Huang Lingyin in Class 1-2. Let me introduce you at lunch."
"Understood."
Houki, the black-haired, ponytailed busty girl, Cecilia, the blonde, vertical-curl ojousama, Charlotte, the blonde girl who uses the male pronoun boku, and Laura, the silver-haired girl with an eye patch. These five, along with the loli twin-tailed Huang Lingyin, are the heroines of the first season of the anime.
"Well then, let me introduce my companion too. Lina."
"Yes, yes!"
Lina, called by me, approached with a cheerful smile.
"I'm Angelina Kudou Shields. Nice to meet you ♪"
"What, you knew Tachibana?"
"Yes, um, shi-shino…"
"I'm Shinonono Houki. Houki is fine."
"OK. Houki is right, Jun and I were classmates at our previous school."
"Oh, is that so?"
Good, good, it's exactly according to the cover story we rehearsed beforehand. I was worried about Lina since she's bad at lying.
◇◇◇◇◇◇◇◇◇◇◇◇◇◇◇
After that, there were lectures, and the gazes from the girls in the class were intense. However, with the homeroom teacher Orimura Chifuyu—a cool beauty with long black hair tied in a single knot, wearing a tight skirt—and the vice homeroom teacher Yamada Maya—a busty woman with a baby face and glasses—intervening, the class progressed and the lunch break arrived in no time.
As the lunch break began, Ichika guided us to the cafeteria. Of course, the heroines and Lina followed, and the students along the way opened a path for us, making it look like a small feudal lord's procession. I was extremely conspicuous.
At the cafeteria, the loli twin-tail was already waiting at the entrance, as if she had been informed beforehand.
"You finally made it. I'm Huang Lingyin, Ling is fine."
"I'm Tachibana Jun."
"I'm Angelina Kudou Shields. Call me Lina."
"Jun and Lina, nice to meet you."
Houki calmed Ichika, who was grumbling, "I was supposed to introduce them," and we all ordered what we wanted and sat down at a table large enough for everyone.
And while eating the ginger-fried pork set meal, trying hard to ignore the surrounding stares, I immediately used my modification ability and asked Ichika a question.
"Hey Ichika, do you have a girlfriend?"
—Clatter
Oh, all the heroines are visibly upset. Ichika, on the other hand, looked completely unfazed.
"A girlfriend, you mean someone I'm dating? No, I don't have one."
"Is that so? I thought you might be dating one of the girls like Houki."
"No, that's not right. They aren't girlfriends; they're important comrades."
"I see."
Ichika waved his hands, laughing as he denied it, but he was probably unaware of the looks he was receiving from everyone present, including the heroines.
"Um, Ichika, are you a homo? You're not, right?"
"Bwuf!"
"Hey Lina, you can't ask that!"
"Shields-san, I'm not! I'm not a homo!"
Lina's sudden bomb erased the previous tension.
But with this, the wedge has been driven into the heroines.
The question I asked in the cafeteria was a trigger for a consciousness modification. Two modifications were activated: [When Ichika says "I don't have a girlfriend," everyone in the academy's affection for him drops to 0] and [The lost affection is multiplied several times and transferred to Jun and Lina]. That's why the stares directed at Ichika became so intense.
◇◇◇◇◇◇◇◇◇◇◇◇◇◇◇
After school, Lina and I, who told Ichika and the others that we were going to get our dorm keys, headed not to the faculty room but to the arena, the IS training ground.
"So, Jun, what are you planning to do now?"
"Naturally, I'm going to make the academy students my female slaves. But…"
Learning from the lesson of increasing female slaves indiscriminately in the DxD world last time, I decided to be selective about the women I make my female slaves in this world.
"I thought you would make all five girls who are close to Ichika your female slaves."
"I'll only take two this time."
"You're cutting it down quite a bit."
"Yes. And, as for the remaining three… Lina, I'm leaving it to you."
"Me?"
To Lina, who froze, pointing at herself, I explained why I brought her to this world.
"So, I'm the one who's going to corrupt the remaining members?"
"That's right. You can handle it, right, since you've dealt with Stardust members?"
"Well, that was part of my duty as the Stars Commander-in-Chief, and both Claire and Rachel were very responsive… Wait, what are you making me say!"
"You said that yourself… Anyway, after the incident at lunch, their favorability towards Ichika plummeted. We'll take advantage of that."
"Ah, so that question was intentional after all."
"And now, all that's left is for me to select and make them my female slaves based on my own discretion and prejudice."
"By the way, who are the two you're making your female slaves?"
"That would be…"
Telling Lina the targets and arriving at the arena happened almost simultaneously.
◇◇◇◇◇◇◇◇◇◇◇◇◇◇◇
As the blue IS flying over the arena descended to the ground, I approached the pilot of the unit, Blue Tears, Cecilia.
The IS suit Cecilia was wearing was quite erotic. With an appearance like a school swimsuit, the shapes of her breasts, hips, and pussy were clearly visible; there was no way it wasn't erotic.
"Oh, Jun-san, are you here to observe?"
"Yes. As expected of a dedicated unit pilot."
"Fufu, naturally."
The IS is a block of black boxes, and the core part, in particular, can only be manufactured by the developer, Shinonono Tabane—Houki's older sister. Furthermore, because Tabane disappeared after leaving behind 467 IS cores, the current situation is that countries are using these 467 cores distributed among them. Therefore, those who have been loaned a unit adjusted for personal use by their country, the dedicated unit pilots, are regarded as a cut above other IS pilots. Cecilia is one of them, also holding the title of British Representative Candidate—a selected candidate for the IS international tournament Mondo Grosso.
"This is quite timely, Jun-san. I actually have something I wanted to discuss with you. Do you have some time later?"
It's here. It's fortunate that Cecilia initiated the conversation without me having to.
I agreed and followed Cecilia, leaving the pit and entering the changing room. There was no one inside but us. I used my modification ability to send everyone away. In fact, in this academy where everyone but Ichika is female, it would be extremely dangerous if someone else were in the changing room.
"So, the matter I wished to discuss with you, Jun-san, is… Nn-nn!? ❤️"
Without letting her finish, I grabbed Cecilia's butt and stole her lips. I sank my fingers into her soft buttock flesh through the IS suit, and ravaged her mouth with my tongue, enjoying her sweet saliva.
When I shifted my left hand toward her crotch, viscous love juice soaked my fingers up to my wrist. Cecilia's face, when our lips parted, was completely melted, and my cock was on the verge of full erection, desperate to violate her.
"You don't have to say it. Cecilia, you want to switch from Ichika to me, right?"
"That is correct, I don't care about Ichika-san anymore!"
"You want to have sex with me, Cecilia, right?"
"Yes! ❤️ I want to make my pussy your exclusive hole! ❤️"
Having gained an affection level multiplied by several times the amount lost for Ichika, she couldn't suppress her desire to have sex with me. Cecilia pulled out her erect-nippled breasts from the side of her IS suit, pushed aside the fabric over her crotch, and opened her pussy. How much I had longed for this sight since her first appearance in the anime.
Her firm breasts, soft hips, and pussy twitching desperately for something. The moment had arrived for me to make them all mine. I'll be honest. I was just as excited as when I made Erika my female slave.
"Cecilia, become my female slave."
"M-Me, Jun-san's female slave? I would be honored! ❤️"
Cecilia was surprised for a moment, but quickly accepted with a radiant smile. Since this is the IS world, why don't we perform the ritual while she's still wearing the IS suit?
◇◇◇◇◇◇◇◇◇◇◇◇◇◇◇
"I, Cecilia Alcott, vow to dedicate my body and soul, including my pussy, as the female slave of my Master, Tachibana Jun! ❤️"
—Chu ❤️
"I'm going in."
"Yes! ❤️"
Foreplay was out of my mind. Desperate to fuck Cecilia quickly, I slammed my cock straight into her soaking wet pussy.
"Hyaaah-aah-aah-aah! ❤️ J-Jun-san's cock just took my virginity! ❤️"
"Does it hurt?"
"I'm fine! ❤️ Now, please thrust deep into my vagina many times! ❤️"
"Yes, I'll do just that."
—Zuchu, jubub, jupp, guchu
"T-This is it! Jun-san's, my Master's cock! ❤️ With every thrust, the pleasure comes, aah! Yaah! Deep inside my pussy, it's tingling! ❤️"
"Inside you, Cecilia, feels so good…!"
What is this? This truly feels amazing! It's a clinging pussy, different from Honoka's squeezing pussy. The folds of flesh are hitting the sensitive spots of my shaft perfectly!
—Pang! Pang! Pang!
"Intense, it's so intense! ❤️ Ahi! I'm being trained! The shape of Master's cock is being taught to my pussy! ❤️"
"Cecilia's breasts…!"
"Aahnn! ❤️ Having my breasts squeezed feels good too! ❤️ Both my breasts and my pussy are being taught by Master, and I'm, aaaah-aah-aah-aah! ❤️"
"Cecilia, you are mine!"
"Yes! ❤️ Cecilia Alcott belongs to Master! So, please remove all traces of Ichika-san from inside me and dye me with only Master! ❤️"
Although we started in a face-to-face standing position, I realized I had conquered her vagina with Cecilia lying on the floor with her legs raised, a so-called seed-planting press position.
I moved my hips aggressively, ravaging the squishy-wet Cecilia inside. I covered her mouth again, whose moans were gradually growing louder, and intertwined our tongues.
"Cecilia, I'm coming!"
"Hiin! ❤️ I'm about to come too! Give me your semen deep inside, deep inside my pussy! Make me yours alone! ❤️"
"Kuh, haaah!"
"Ahi, I'm coming! I'M COMING! Ah, aah-aah-aah-aah-aah-aah-aah-aah-aah-aah-aah!! ❤️"
I ejaculated an incredibly thick stream of semen deep into Cecilia's vagina, surprising even myself. I lowered her legs and embraced Cecilia in a face-to-face position, still connected.
"Now I am truly Master's, aren't I… ❤️"
"Yes. From now on, you will open your legs immediately when I ask, so be prepared, okay?"
"Yes! ❤️ I await your call! ❤️"
◇◇◇◇◇◇◇◇◇◇◇◇◇◇◇
Afterward, I showered with Cecilia and changed into our uniforms, then took her to the faculty room. After receiving the dorm key from Yamada-sensei, I took Cecilia straight into the room.
"Jun, welcome back."
"Lina-san?"
Cecilia froze when she saw Lina in the room. I had modified the situation so we were in the same room, thinking it wasn't necessary to separate them.
And that wasn't the only reason Cecilia froze. On the bed where Lina was sitting, there was—
"Fu-hii ❤️"
"L-Laura-san!?"
"Laura became my pet today. Right?"
"Ahi ❤️ I-I am Lina's pet!"
—the eye-patch girl, lying naked and spaced out with an ecstatic look.
It must have been because Lina's technique was incredible. The German soldier had been reduced to a mere female dog.
"How about it, Cecilia? Our academy life is going to be fun, isn't it?"
"...Yes ❤️"
Cecilia, who was kneading her own breasts and fingering herself over her skirt and stockings, using Laura's disgraceful state as her subject, had an alluring expression.
(I've made arrangements for Cecilia and the others, but I should set up something for Ichika as well.)
◇◇◇◇◇◇◇◇◇◇◇◇◇◇◇
In the room where his roommate had changed from Houki to Charlotte, and was now just him, Ichika was tormented by a nightmare—no, a wet dream.
"Your small cock, Ichika-san, can't reach this far, but I'm being penetrated deeply!"
"Ahiin! ❤️ Not there!"
A dream where his classmates, Cecilia and Laura, were being violated by someone other than himself. In the dream, the two were making sweet sounds with ecstatic faces.
"Cum inside! Pour lots of your cock juice into my pussy! ❤️"
"I'm coming-coming-coming-coming-coming! ❤️"
"AAAAAAHHHHHHHHH!!"
Just before the moment Cecilia and Laura were internally ejaculated on in the dream, Ichika woke up with a scream.
His breathing was ragged, and his face was sticky with an unpleasant sweat.
He turned on the light in the room and headed to the sink. After washing off the sweat with water and wiping his face with a towel, his breathing finally returned to normal.
"Why did I have a dream like that…"
Recalling the contents of the dream, a part of his body began to react sensitively. Unable to restrain himself with reason, Ichika sat on the bed and pulled down his pajama pants.
"Cecilia… Laura…!"
He began to masturbate, substituting the person who was fucking his classmates in the dream with himself. And, with a consciousness modification, he pressed a pair of female panties—Cecilia and Laura's underwear, which he had somehow acquired—to his face, savoring the owner's scent that lingered on the fabric.
"I'm not small-cocked! This is normal!"
Although he muttered that to himself like self-hypnosis, his cock, even at full erection, was smaller than the average Japanese size in peacetime.
Rubbing his dick, which could be hidden by three fingers, up and down, Ichika ejaculated in less than a minute. A thin, non-opaque liquid slightly stained the floor of the room.
"Ah… what am I doing…"
Falling into self-loathing during the post-ejaculation 'sage time,' he quickly cleaned up, turned off the light, and slipped back into bed.
That's why he didn't notice.
He didn't notice that the two pairs of underwear he was just holding were gone.
Nor did he notice that the stealth-spec searcher surveillance camera I had prepared was recording everything.
