June, 2096
In June of the year 2096 of the Western calendar, Kashima Retsu, an elder of the Japanese magic world and a retired Major General of the National Defense Force's Ground Army, visited the Ninth Magic Development Research Laboratory with his son and current head of the Kashima family, Makoto Shinon.
The Ninth Laboratory, as a national institute, was closed after the Third World War , but it continues to operate as a private research institute funded primarily by the "Nine" families, led by the Kashima family. Deep inside the lab, a row of life-sized dolls lined up before the two Kashima men.
"What's the progress?" Shinon asked.
The chief researcher who had guided them smiled triumphantly at Shinon's question.
"The Parasites' establishment in the military humanoid machine 'Gynoids' is proceeding smoothly. We have already completed 16 prototypes of the 'Parasite Doll'
"Sixteen, is it?"
"Yes. The Parasites are currently dormant within the Gynoids due to the Allegiance Ritual Formula. We can start the performance tests anytime you give the command."
The chief's words exceeded Shinon's expectation; he had thought practical performance tests were still far off. However, Retsu had a different idea.
"You know that an inter-High School Magic Competition is held every year in August, don't you?"
"Huh? Yes, I am aware of that, but..."
"This year, an event called 'Steeple Chase Cross Country' has been adopted there. It's a long-distance obstacle course race where students aim for the goal, overcoming physical obstacles as well as magical interference."
Hearing this, the chief immediately grasped Retsu's intention.
"You plan to use the Parasite Dolls as the obstacles?"
"If we use the Parasite Dolls, no military magic users will be injured by a counterattack from the students. If we limit their strength with the Allegiance Ritual Formula, we won't inflict serious injuries on the students, either. It's the perfect opportunity for the first operational test."
While the chief nodded in agreement with Retsu's plan, Shinon expressed his concern.
"But, former head, will the Operating Committee approve?"
"They will give their assent. At this point, the Operating Committee has already had the Steeple Chase race forced into the competition by the intervention of the National Defense Force. They can't possibly turn down our request now."
"...Understood," Shinon reluctantly conceded, a look of hesitation on his face.
No one mentioned precautions in case of information leaks or who would take responsibility. They fully intended to shift the blame to the National Defense Force, which had intervened first.
Unseen Details
Yet, until the very end, everyone, including Retsu, failed to notice—or rather, was unable to notice —that five of the 16 Gynoids lined up before them (those containing the cultured Parasites) were "too similar to living human beings." Not only their faces, but their entire skin surface, including limbs, breasts, and even their private parts—all five were female-type—were faithfully reproduced. Such realism was unnecessary for mere combat use.
Someone who saw these Parasite Dolls, which the Ninth Lab researchers unconsciously created through Jun's alteration ability, would surely have said, "They look just like Combat-Cyborgs."
Jun's Thoughts and the IS Project
About a month and a half had passed since the two Nanagusa twins became female slaves. It was around the time the student council and club federations would start preparing for this year's Nine Schools Competition (Nine Schools Battle).
(Well, this year they're going to be in an uproar over the Parasite Dolls, though.)
It was currently June, but the Operating Committee should send the requirements for this year's competition next month. And there would be a change in the event types—three out of six events would be swapped. That was why President Azusa-senpai was sure to be in tears. The reason for the change was that the "Scorching Halloween" incident last year had energized the hawks within the National Defense Force, who then intervened with the Nine Schools Competition's Operating Committee and forced in more military-focused events. This was incredibly annoying to Tatsuya.
And in one of the swapped events, the Steeple Chase Cross Country obstacle race (with physical and magical interference), the old man of the Kashima family was going to use Parasite-sealed Gynoids as obstacles.
(Well, I'm going to make that fun, too.)
Through my alteration, I've made five of the 16 Parasite Dolls erotically strong, like the Combat-Cyborgs from the Lyrical Nanoha world. On the day of the competition, I'll have Tatsuya deal with the other eleven Parasite Dolls, and the erotic five will sexually assault the participating athletes (excluding Miyuki and her group). The goal is to make Ichijou and Kichijouji come close to a techno-break. I took the women of the Ichijou family, so at least let's give them a peaceful climax at the Nine Schools Competition.
The IS Project
I was relaxing and thinking such things in my villa world when—
"Jun-kun!!"
"Tachibana-kun, I have something to discuss with you."
"Hm? Taba and Suzune. What is it?"
Taba looked as cheerful as usual, and Suzune, surprisingly, wore an excited smile. Did something good happen? By the way, I was happy to see them both naked.
"Guess what! We finally succeeded in incorporating magic theory into the IS!"
"Magic theory into the IS? Is it going to fly dry ice from the IS or something?"
"Boooo! Totally wrong!"
"Please look at this," Suzune said.
I took the mobile device Suzune handed me and read the displayed content. ...Seriously?
"If this is true, things are going to get interesting."
"Right, right?! But we don't have anywhere to test its performance..."
"Ideally, we need a situation where it can be operated for a long time under severe conditions, such as combat..."
Aha, I see. They want to operate this modified IS in an "alternate world," specifically one where combat occurs.
(Combat, combat, huh... Ah! I've got the perfect world!)
In that world, they can unleash the IS's super firepower, there are plenty of targets, and they'll be able to harvest high-quality female crotches (manko). It's two birds with one stone.
"Understood. Taba, please prepare a large quantity of these modified IS units."
"A large quantity?"
"Yes. Enough for all the students of Class 1, Year 1, of the IS Academy."
"Ohh! You're going to take us to a world where we can use so many?! Woooow, I'm feeling motivated!"
Taba pumped her fists several times and then ran off, leaving Suzune behind. Hmm, she's as free-spirited as ever.
"By the way, what kind of place is the world you've chosen for this experiment?"
"That would be..."
"A hell where extra-terrestrial species called 'BETA' are massacring humans."
Deployment in the Muv-Luv Alternative World
—Muv-Luv Alternative world, Kashgar Hive, Xinjiang Uyghur Autonomous Region, China
"Seeing it again, it's really an unfair advantage," I said.
Driving a large commuter (heavily customized) through a giant underground tunnel called the Drift, I watched the IS Academy students fly around the Drift, firing bullets at BETA many times, even dozens of times, their own size.
The Tank-class that crushes everything with its abnormally positioned mandibles. The Destroyer-class that rushes at tremendous speed, its front covered in hard carapace. The Grappler-class that wields its sturdy arms. The BETA pouring out of the depths of the Hive were being annihilated without a single IS being shot down. Occasionally, attacks would come from the Laser-class—individuals that shoot lasers from a giant, eyeball-like projection organ —but:
"Oops, got hit."
"Are you okay?"
"Totally fine, the shield energy is still full."
What would the humans of this world think if they saw an IS completely unscathed even after a direct hit from a Laser-class attack? Even their strongest weapon created to fight the BETA, the manned bipedal tactical robot Tactical Surface Fighter (TSF), would surely evaporate along with the cockpit if subjected to the laser for even ten seconds.
"IS is amazing, isn't it? Rinna, you rode one in that other world, right?"
"Yes. I flew through the sky exposing my crotch, just like them."
"Wow, so erotic ❤"
Erika and Rinna were in the back seat of the commuter, and Taba and I were in the front. Taba seemed delighted with the results. I was also delighted to watch the female students fly around in their IS units with their breasts and crotches exposed after a long time.
"Besides, converting the energy used for magic-based phenomenon alteration into IS shield energy isn't something anyone would easily think of."
Rinna was right. Taba had made it possible for the IS to "automatically draw in Psions from space, and convert the phenomenon alteration energy for IS use." If the IS, which already possesses absolute defense, could get an unlimited supply of energy for it, the BETA wouldn't stand a chance. The commuter had the same modification, and although Destroyers had been charging at us, it was completely fine. In fact, the BETA were bouncing off the commuter's shield and overturning. Long live cheats, seriously.
The four of us who came to this world, plus the 25 students from IS Academy's Class 1, Year 1, excluding those with personal IS units, reached the Main Hall—the innermost area of the Hive—almost non-stop, passing from the Drift through the vertical shaft called the Main Shaft. And there, the Heavy Brain-class, the commander-like existence of the BETA—
"Ew, gross!"
"Are those tentacles? They're squiggly and disgusting."
They were right; the slimy, serpentine appearance with six eyeballs was certainly gross. And as we were talking about it, the tentacles immediately attacked. But...
—Dododododo!
"Whoa~"
"They were all obliterated by the simultaneous firing of assault rifles and machine guns."
Erika and Rinna were dumbfounded. Pitifully, the Heavy Brain-class had all its tentacles blown away and could only repeat the process of regeneration followed by obliteration.
While that was happening, Taba and I got out of the commuter. We were using the IS's protective function to avoid breathing the outside air, just in case.
"Alright, Taba, as planned."
"Roger that ☆"
Taba approached the now-defenseless Heavy Brain-class, took out a device from her expanded territory—a pointed, rod-shaped object with a monitor in the middle —and:
—Gusah!
She thrust it into the Heavy Brain-class. She then operated the monitor, and the regeneration of the tentacles stopped.
"Yes, all right! Heavy Brain-class mastered and controlled ☆"
"That was easier than I expected."
"Of course! This is child's play for Taba-san ♪"
As Taba gave me a thumbs-up, the surrounding girls began high-fiving and cheering. The initial objective was now complete.
We had two purposes for coming to this world. The first was, of course, to test Taba's modified IS. This was an absolute success. The second was to master the Heavy Brain-class. Because...
"Taba, please continue and give commands to the Heavy Brain-class."
"Roger, I will ♪"
At my instruction, Taba began operating the monitor again. And from the Heavy Brain-class, a certain command was sent to the Hives scattered throughout this world.
"In the Solar System's Third Planet, 'Earth,' there exist carbon-based life forms different from the silicon-based life form creators, commonly known as 'Humans.'"
"'Humans' include individuals with the X and Y chromosomes, 'Category Classification Name: Male,' and individuals with only the X chromosome, 'Category Classification Name: Female.'"
"Upon discovery, 'Females' are to be captured, preserved in an aging-element degradation prevention capsule filled with an aphrodisiac gas and sedative gas, and transported to this Main Hall."
In other words, the goal was to use the BETA to collect the female War-Technicians (the name for TSF pilots in this world), the high-quality female crotches of this world. I hope we gather a lot!
"Jun, is that all?"
"Yes. The IS performance test was successful, and the Heavy Brain-class has been mastered and given its commands. All that's left is to go home, but... how about we all take a commemorative photo first?"
"That's a great idea! Everyone~, Jun says we're taking a commemorative photo~!"
Perhaps because they were classmates for a short time, the Class 1 students gradually gathered at Rinna's call. Watching them, Erika smirked.
"That's nice~, those skin-tight suits where their breasts and crotches are completely visible. Ah, I can see their butt-holes, too. I might want to wear one next time."
"That's a good idea. Should we adopt it as the Uniform for Class S of the First High School?"
"Haha, that might be fun ❤ Since going naked is the default at school and in the villa world recently, an accent like that is very welcome to prevent boredom ♪"
Since Erika was also enthusiastic, I'll seriously consider it. I might also include the pilot suits worn by the War-Technicians in this world—the War-Technician Enhancement Equipment—as a candidate. I always thought those rubber-suit-like outfits that tightly cling to the body line were sexy despite the lack of exposure.
"Hey, Jun and Erika! Everyone is lined up!"
"Oh."
"Yes, yes."
When called over, their former classmates, who had their IS units in standby mode, were gathered like a school trip group photo, their nipples throbbing hard. Some were even touching each other's crotches—good, keep it up.
"Tachibana-kun, over here~"
"You were Chiba-san, right? Please take the spot next to Tachibana-kun."
"Is that alright?"
"It's fine, it's fine! Chiba-san is Tachibana-kun's female slave, just like Rinna, right? Then you should prioritize masturbating next to Tachibana-kun."
"Ah, I see. Understood ❤"
"Me too, next to Jun. Nngh ❤"
As suggested by Shizume and the others, I stood in the center of the middle row of the three-tiered formation. Erika and Rinna took their positions on either side and immediately began inserting their fingers into their crotches. This was the signal for the surrounding girls to start fondling their breasts and fingers their butt-holes. The Main Hall, once dominated by the BETA, was instantly filled with the sweet moans of females.
Just waiting for this moment, Taba, who was also naked like Erika and Rinna, aimed an SLR camera at us.
"Alright, how are your crotches doing~? Just stay like that, just like that~, with your pleasure faces, say 'Cheese' ♪"
—Click!
"Hauu ❤"
"I'm coming ❤"
"Ahii ❤"
With the shutter sound, several people seemed to have orgasmed. No, wait, everyone came. As expected of Class 1, Year 1, their level of lust is unrivaled by any other class. Erika and Rinna, of course, also came, whispering into my ear as they did:
"I'm coming, next to Jun ❤"
"Jun, you should come too, listening to me and Rinna's cries of pleasure ❤"
My penis became fully erect from Erika and Rinna's ASMR, but I barely managed not to ejaculate. I was seconds away from exposing myself like that Councillor Kanda. Close call, close call.
Preparing for the Return
After the commemorative photo, we withdrew from the Muv-Luv world. We'll return when the BETA has captured and transported the female War-Technicians here.
(Hmm, it's currently 1979... The year after the failure of the Paleologus Operation to capture the Minsk Hive. The setting of the Muv-Luv Alternative spinoff, Schwarzes Marken, is 1983, so it's about five years later.)
If things go well, East and West German female War-Technician crotches will be in this Main Hall... I can't wait!
Kei's Secret Rendezvous
While Jun was preparing for his erotic refill, an obscene event was also taking place in the room of a certain First High School student.
"Haa... Ungh."
"Nngh... Slurp ❤ Lick... Nngh ❤"
The young man, who likely maintains a gentle demeanor at school, was being served orally by a female elementary school student in his room.
"Nnngh... Kei-san, how is it?"
"Ah, it feels good, Ruri-chan..."
Ichijou Ruri appeared before Isori Kei, the student council treasurer of First High School, shortly after the start of May.
"I am Ichijou Ruri, and I will be in charge of your sexual service starting today. Please shower me with lots of affection ❤"
At first, Kei was repulsed by the phrase "sexual service" from such a young girl. However:
"Slurp slurp ❤"
"S-Stop, stop that... Aah!"
"Nngh, nngh! ... (Gulp) Phew, thank you for the meal ❤"
Due to Ruri's fellatio technique, which was incredible for her age, and Kei being an adolescent who had recently had an erotic dream about his former fiancée, Kanon, he was unable to resist the temptation. About a month had passed since then, and Kei was increasingly captivated by Ruri's erotic body.
"Ruri-chan, is it okay?"
"Kiss... Yes, of course."
Ruri, who had been sucking his penis, pulled away at Kei's request. A bridge of saliva formed between his glans and her lips, then snapped. Licking up the residue with her tongue, Ruri began taking off her dress. The rustle of fabric echoed in the room, and Kei hugged Ruri, who was now only in her bra and panties. While their lips met, Kei's fingers began to fondle Ruri's butt.
"Nfuh... Kiss, Kei-san... ❤"
"Ruri-chan... you're going to be mine forever."
"Of course. I would never abandon you like Kanon-san."
Kei's heart was weak. His engagement with Kanon, a relationship once promised for the future, was broken off, and even in a dream, he was told, "Don't come near me more than necessary from now on". The sudden appearance of an erotic girl who adored him was enough to make his heart waver.
"Ruri-chan, I want to come inside you again today."
"You can. My crotch is for Kei-san only. I'm different from someone who cheats on her fiancé with other men."
"That's right, you're different from Kanon. Different from Kanon, who is having sex with a man who isn't me...!"
Led by Ruri, Kei released the emotions he had held back. His anger turned into lust, and while enjoying her cute, squishy twin mounds, he pushed her onto the bed. He then thrust his hard penis, which she had just orally served, into the girl's small slit.
"Nnngh! ❤"
"Aah, Ruri-chan's vagina is so tight, it feels good."
Her smooth crotch, which hadn't even grown pubic hair yet, was being squeezed tight by Kei's average-sized penis. However, even that felt pleasurable to her body, which had been taught sexual techniques by a master from another world—Huang Lingyin, a genius of effort who practiced fellatio to satisfy her master—before being sent here. Her vagina immediately secreted a large amount of arousal fluid to lubricate the penis and the vaginal wall. This made the thrusting easier and induced further pleasure for Kei.
—Pachun! Pachun!
"Ah, ah, aah! Kei-san's penis is kissing my womb a lot ❤"
"Ruri-chan's crotch feels good!"
"Is my crotch good? ❤"
"Yes, it is! I like Ruri-chan's loli-crotch more than Kanon's!"
"Hehe, I'm happy ❤"
Kei uttered words that would be unthinkable in the original world. If Kanon abandoned him, he felt he had the right to deny Kanon. With those dark emotions mixed in, Kei's thrusting sped up. Ruri's hips moved in sync, and the sound of arousal fluid splashing from the coupling echoed through the room.
"Ruri-chan, I'm going to come! Ungh, kuuuhh!"
"Ahih! ❤ Aahn! Aaaaaaah! ❤"
After a moment of spasming hips from their simultaneous climax, Kei, having ejaculated completely into her womb, collapsed onto Ruri on the bed. The two held each other, savoring the afterglow.
Kei would never know that this moment of happiness was orchestrated by his junior...
