The day of the National High School Magic Theory Thesis Competition.
Arriving at the venue, the trailer carrying the stage equipment had already unloaded its gear, and Iori-senpai was in the middle of directing the transportation inside the hall.
In the original story, Erika and Kanon would have been glaring at each other here, but such a thing does not happen in this world. That is because both of them are my female slaves.
"Now Chiyoda-senpai is also Jun's female slave, which means she's one of us. So let's stop this silly bickering from now on."
"You're right. I don't want to cause trouble for Tachibana-kun."
And so, with no particular issues, Erika quietly went to the audience seats with Mizuki, Leo, and Mikihiko. Kanon, meanwhile, continued to guard Iori-senpai.
Hmm? What happened with the detention center incident? That part is completely cut. I'll just say that Tatsuya, Mari, and Mayumi successfully countered Lü Ganghu, who came to silence Sekimoto.
"Jun, you're already here."
"Hey, you two. It looks like you're the last ones."
"Is that so? I thought we arrived on time."
The Shiba siblings, who had just arrived, looked a little surprised. They were the last because the roads were clear and the trailer had entered the venue early.
"By the way, when is First High's presentation?"
"It's at 3 in the afternoon."
"It's 8:30 AM now... Ugh, that's over a six-hour wait."
"It is. But we won't be bored, as we have to guard the equipment and do final checks."
"That's for you guys. Is Miyuki joining in too?"
"Yes. If possible, with Onii-sama."
Typical siscon, she's consistent.
"So, what will you do, Jun?"
"Do what?"
"Help us out or something."
"No, no. Unlike the Nine Schools Competition, I'm not a member."
"I see... Then, with Erika and the others?"
"Yeah, I'll quietly sit in the audience, watch the other schools' presentations, and doze off."
"Oh my, Tachibana-kun."
"That's like you."
After being laughed at lightly, I parted with the siblings and headed for the audience seats... but before that, I went to a private communication room inside the venue. Entering the room, which I had received a contact for beforehand,
"Tachibana-kun, I've been waiting for you."
Mizuki was waiting, her cheeks flushed. She closed the door and began to slip out of her uniform, becoming completely nude in an instant.
Then, spreading her already-wet pussy, she slowly swallowed my rod, which was positioned on the chair I was sitting on.
"Hah... Nnh, Fuuh..."
Mizuki's cries of pleasure echoed inside the soundproofed private room. Her body, in a position where she was straddling me and being embraced from behind, trembled faintly.
"Hih, Ah... Hahih..."
"You were just with Erika and the others, and you're already like this?"
"I'm s-sorry... But, I couldn't resist, I wanted Tachibana-kun's, my Master's penis so badly! ❤"
As Mizuki thrust her hips, panting heavily, I slowly rocked my body up and down.
"Hiaaah, Hahih! ❤ Hyaah!"
The honey pot gripping my rod made lewd, squelching sounds. With every sound, sweet moans escaped Mizuki's lips.
My cock-shaped pussy also writhed obscenely with a Gnyu, Gnyu sound.
"Mizuki, stick out your tongue."
"Yes ❤ Eh ah... Rero... Reroerero... ❤"
When I withdrew my tongue from hers while thrusting into her vagina, saliva dripped down, wetting her ample chest.
Meanwhile, her female flesh contracted delightfully with a Kyuu sound.
"Aahnn! ❤ This is it! ❤ This is what I wanted! ❤"
My cock and her pussy rubbed against each other with a suggestive Zuryu, Zuryu sound.
In rhythm with that movement, her vaginal folds wrapped around my shaft with a Juru, Juru sound.
"Oh, my pussy! My pussy feels so good! ❤"
Led by the pleasure in her pussy, Mizuki started thrusting her hips back and forth even more intensely than before.
Furthermore, when I played with her nipples from behind, the tightness of her pussy increased.
"Please, torment my breasts a lot too! ❤"
"Honestly, Mizuki has great breasts. Mikihiko must be crying with regret."
"Yoshida-kun? No way, my breasts belong to my Master! ❤ I'll never give them to anyone else! ❤"
Kuh! I wish I could let the two of them in the original world hear that! When she says such a line with a melted face, my semen levels skyrocket!
"Mizuki, I want to come soon. Where should I do it?"
"I-Inside my pussy, of course! ❤"
"Understood."
I thrust deeper into her thoroughly wet honey pot, while also kneading her breasts, attacking her from two directions.
"Kuh!!"
"Ahh, aaaaahhhnn! ❤ Nnnnnnnnnnnnnnnnnnnnhhh!! ❤"
As I ejaculated purely out of lust, I strongly squeezed her nipples, and a high-pitched cry of climax erupted from Mizuki.
"It's amazing... ❤ Something hot, in my pussy... ❤"
In rhythm with the ejaculations being expelled, she wiggled her hips, making the flesh wrapped around my cock writhe and suck up the semen.
"M-Mizuki..."
"Aaaahhhnn... ❤ My Master! ❤"
Satisfied with having sucked up the semen, Mizuki's upper body fell forward onto mine. Seriously, what an erotic female slave. It's truly worth bringing her back with me.
I continued to manipulate Mizuki's twin peaks for a while, keeping my rod inserted into her vagina.
◇◇◇◇◇◇◇◇◇◇◇◇◇◇◇
Meanwhile, Kyoko Fujibayashi visited First High's waiting room where the Shiba siblings were.
"By the way, Fujibayashi-san, is it alright for you to come to First High's waiting room?"
Tatsuya was concerned about "whether his true identity would be exposed by her, a member of the National Defense Force, making contact." Of course, he phrased it in a way that someone slightly knowledgeable about the circumstances would take it to mean, "Is it acceptable for her, an O.G. of Second High, to be in a rival school's waiting room?"
"It's fine. It's convenient to have many titles at times like this. It's not unnatural for me, a technical officer of the Ministry of Defense, to visit you, who demonstrated such advanced technology at the Nine Schools Competition, is it?"
"I see."
In that case, Tatsuya had nothing more to say. Miyuki had only managed a wry smile since Kyoko arrived.
"Well, enough with the preamble... Which do you want to hear first, the good news or the bad news?"
"That's a familiar setup... I'll take the good news first."
"The good news. The movable suit we talked about is complete. Captain Sanada sent a message that he's bringing it over tonight."
"I see. As expected."
Tatsuya had asked him to make it because he couldn't create one capable of combat, but he hadn't expected it to be completed so quickly. Hence the praise.
"Then, for the bad news. The matter we discussed doesn't seem to be over just yet."
"Is there a problem?"
"Look at this for the details."
She said, handing a data card to Tatsuya.
"The matter." That was the incident two days ago when they captured almost all of the field operatives of the spy unit (though their commander, Chen Xiangshan, escaped). Indeed, the details would be something even wireless transmission would hesitate to carry.
"It might get messy."
"Understood. We'll prepare on our side as well."
It was her position, and the battalion's, which regarded them as valuable and powerful assets, that prevented her from saying, "Don't get involved."
◇◇◇◇◇◇◇◇◇◇◇◇◇◇◇
9:00 AM. The National High School Magic Theory Thesis Competition began in a solemn atmosphere. Unlike the Nine Schools Competition, which is a contest between students, this is a presentation aimed at people from universities, corporations, and research institutions. It would naturally be more formal.
As I told Tatsuya, I was going to doze off in the audience... but I couldn't, so I was timing things in the coffee room.
"I think it's an honor to have the 'Mist Phantom' interested in my work."
"...I never thought the 'Electron Sorceress' would know someone like me. The honor is mine."
Using my alteration and stealth ability, I listened to the exchange between Haruka and Fujibayashi-san while sipping coffee at the next table. The nicknames they called each other were quite chuunibyou-inducing.
Well, it seems the exchange ended with Fujibayashi-san giving Haruka a warning. Now, time to release the alteration.
"Excuse me, may I speak to you for a moment?"
"!"
"T-Tachibana-kun!?"
They both looked at me with surprised faces, having checked that no one was around before I suddenly appeared.
"Tachibana-kun, the presentation has already started..."
"Listening to Second High's content was making me sleepy, so I voluntarily left before I could be kicked out for snoring."
"Pfft."
"Eeh~..."
It seems Fujibayashi-san found it amusing. After an initial slight burst of laughter, she was holding her mouth to suppress more. Haruka, though, looked exasperated.
"So, do you have business with us... or rather, with the teacher there?"
"No. Fujibayashi-san, I have business with you."
"...With me?"
She looked at me with a heavily suspicious expression. Of course, a student she'd just met having business with her would put her on guard.
"I apologize, but could I trouble you to accompany me for a moment?"
"...Alright."
"Ah, Haruka-sensei too."
"M-Me too?"
"Yes. It's a rather important matter."
Saying that, I led the two of them to an empty room (already secured with my alteration ability). It was about the size of a conference room for ten people.
"So, what business do you have with me?"
"First, let me introduce myself. I'm Jun Tachibana from Magic High School 1-E. Perhaps 'Tatsuya's classmate' would be easier to understand."
"I see. I am—"
"Ah, it's alright. Second Lieutenant Kyoko Fujibayashi, of the National Defense Force, 101st Brigade, Independent Magic-Equipped Battalion."
"What!?"
Having her hidden title revealed, Fujibayashi-san looked shocked. Haruka also seemed too surprised to speak.
"H-How..."
"How do I know, you ask? That's a trade secret. I know various other things too. Like 'Special Lieutenant Tatsuya Daikoku,' and Material Bu—"
"That's enough, I understand!"
Oops, I was cut off. Well, there was a lot of content that would be a problem if Haruka heard it, let alone just me.
"What exactly is your goal...?"
"Do you really need to ask that? You know the answer."
"Yes... I understand, I will comply with your demand."
Saying that, she put her hand on the buttons of her blouse.
"In exchange for not revealing the information you know, I will become your female slave. Is that acceptable?"
"That is acceptable. Of course, you know what a female slave entails, don't you?"
"Of course. It means 'wrapping your penis with my fully ripe pussy and having you spurt semen into me.'"
Saying such a thing with a straight face, Kyoko became completely nude and pulled my cock out of my pants.
"I, Kyoko Fujibayashi, swear to dedicate my mind and body, including my pussy, as the female slave of my Master, Jun Tachibana."
—Chuu ❤
"Well then, I'd like to start right away... but first, take a look at this."
I took out my mobile device and showed the recently-vowed Kyoko a certain video.
"A-Ah...!"
"Is that you, Fujibayashi-san?"
As Haruka, who looked over my shoulder, said, it was the video of her masturbating that had been sent via Mayumi.
"Th-Then, it was for you all along?"
"That's right. In other words, Kyoko, it was predetermined that you would become my female slave."
"S-Such a thing... A-Aah! I'm coming!"
Perhaps excited by the fact that she had been watched all this time, she squirted with a Pshuu sound. Wow, so Kyoko actually has a nature that gets aroused by being watched. My kink collection is expanding.
"Wow, your pussy is all slippery now~"
"N-No! Don't finger-squish it!"
"Hold on, Haruka, the ritual is still ongoing."
"S-Sorry. I just couldn't help it..."
As Haruka apologized and pulled her finger out, passion fluid mixed with the scent of a female was thickly scraped out and dripped onto the floor. No preparation needed, I guess.
I had Kyoko climb onto the conference table and inserted my rod into her pussy in the missionary position.
"Ngaaaahhh!"
"No blood, as expected. It's nice that I can ravish her without worrying about it from the start."
The vaginal opening, which easily swallowed my rod, squirmed and sucked on its own, its mucous folds winding around and inviting me deeper.
"My pussy, all the way to the back... I've been completely ravaged... ❤"
"Which one is better, yours or your fiancé's?"
"A, Ah..."
The spiteful question made her emit a voice like her throat was dry. But when I thrust powerfully into her!
"Ahii! This penis is better! This penis feels better than that person's!"
"Well done. Then, let's go for more!"
"Aaaahnn! I'm submitting to my Master's penis... I'm begging for more... I'm whining for more! ❤ Move, penis, thrust into my pussy! ❤"
In response to that demand, I pulled Kyoko's hands and thrust my hips intensely against hers.
The sound of flesh colliding echoed, and pleasure spread throughout her body.
"Ngh-ah, Ahahaaaahhh! ❤ There, right there! Amazing... Nnghauuuhhh! ❤"
At that moment, a hand snuck out from the side and grabbed my arm. Haruka took the grabbing hand into her skirt and started gyrating her hips, as if begging me to play with her pussy.
"Hey, Tachibana-kun..."
"Honestly, between Mizuki and Haruka, you're all impatient female slaves. ...You can say the magic words, right?"
"Y-Yes...! Master, please squish and grind Haruka's pussy intensely! ❤ Hyaaahn! ❤"
The slapping sound of flesh colliding from Kyoko's pussy and the squelching sound of passion fluid being stirred from Haruka's pussy echoed, creating a lewd duet.
"My penis feels so good, I'm coming! I'm coming with the penis!"
"I'm coming too, with my Master's finger!"
Synchronizing with the two of them climaxing, I also fully ejaculated inside Kyoko's vagina.
"Kyoko-san, now we are co-slaves, female slaves of the same Master..."
"I suppose so... Ah, my Master's penis... ❤ Ah-fuu ❤"
Kyoko was sprawled out on the conference table, basking in the afterglow of her climax, and Haruka was sitting on a chair, her hips twitching. Both were picturesque compositions.
"Kyoko, though you are now my female slave, remain in the Magic-Equipped Battalion for a while. Carelessly resigning might expose the fact that you're a female slave."
"Understood ❤"
I really want to take her home with me, but doing that would break the original scenario too much. Patience, patience.
Looking at the clock, it was almost 11 o'clock. It should be around the time Suzune-senpai arrives at the venue and Kyoko receives an emergency call.
(Lü Ganghu, who was supposed to be transferred to Yokosuka, should have escaped, and then combatants and armored vehicles should be sent from the Great Asian Union's disguised landing craft.)
Knowing such a future, I still decided to leave the resolution of this 'Yokohama Disturbance' to Tatsuya and the others, contemplating whether to "make Suzune-senpai a female slave inside the evacuation helicopter or make Azusa-senpai a female slave inside the shelter."
