Author's note

So, I've watched Season 2 of Maken-ki a long time ago, and I loved its Episode 1. The pervert got cock-blocked by Ooyama Takeru, but what if Takeru failed to stop him? This is a what-if chapter. I hope you guys will love it. Now then, let's get to it.

XXX

The Tenbi Academy used to be an all-girls school. Recently, it has been converted into a co-ed one. However, Tenbi isn't an ordinary school. Its students are trained to harness the power of Elements in order to protect themselves and the innocent civilians. They are also granted gears known as Maken. All the students of this school are being watched over by a student body called Maken-ki, which is similar to the Disciplinary Committee and the Student Council of a regular high school. Ooyama Takeru, the protagonist of this story, has joined Maken-ki along with his best friend Usui Kengo after being persuaded by his childhood friend, a second-year called Amaya Haruko.

Recently, trouble has been brewing in Tenbi Academy. A lingerie thief is out there stealing underwears of female students. To make things worse, the thief also took embarrassing pictures of his victims. Whoever they are, they're very elusive. A clever deduction from Takeru led them to believe that the thief's M.O. is stealing bra based on cup sizes. He began with A and worked his way up to G. If Takeru's deduction is correct, the thief's next target is students who has H-cup sized busts.

All eyes fell to Haruko and another member of Maken-ki called Akaza Chacha. Both of their cup sizes are H.

Incidentally, the one with the next biggest bust size is Rokujou Minori, who is the principal of Tenbi Academy. Her cup size is I. Finally, the one who owns the title of the Bust Queen of Tenbi Academy is Nijou Aki, who works here as the school nurse and has a pair of K-cup breasts.

A fellow Maken-ki member by the name of Shinatsu Azuki proposed to use Haruko and Chacha to lure out the thief. Another Maken-ki member, a first-year called Uruchi Minaya, on the other hand, is against it. She absolutely adores Haruko, and can't stand the thought of letting her precious senpai be exposed to danger like that. However, Haruko has a thought of her own.

"I'll do it!" Haruko declares. "In order to prevent anyone else from falling victim to the underwear thief, I'll become the bait!"

"Are you sure, Haru-nee?" Takeru asks while looking really concerned.

"To be honest, I'm a little scared." Haruko confesses. "However, I believe that Take-chan-no, the entire Maken-ki will protect me!"

And so, it's been decided. Both Haruko and Chacha are to stay inside the girl's changing room next to the pool. This changing room has a single entrance and is difficult to sneak into, which is why it was chosen. Everyone else are standing guard near the changing room and will charge in on the first sight of trouble.

While Haruko and Chacha are inside the changing room, they got changed into matching idol outfits. The one Haruko wearing is blue-and-pink in color. She's also wearing her signature pantyhose. As for Chacha, she's wearing a yellow-and-green outfit, and her feet are bare.

"Why do we have to get changed into this?" Haruko couldn't help but ask.

"It's to lure in the culprit, of course!" Chacha replied cheerfully. "Do you like the colors? They're brand new!"

"Jeez, I wish I'm as carefree as you are. Still, it's best if we're careful. After all, we don't know how the thief is going to attack us."

As the two girls are talking, a black ooze appears from the ceiling where the ventilation fan is installed. Chacha was quick to notice it.

"Hey, what's that?" she asks while looking alarmed.

Haruko notices it too.

"Stay back, Chacha!"

The two of them took a few steps back in a hurry. As they watch, the ooze drips to the floor and transforms into some sort of mini beastman. The beastman is only two feet tall. It has no beast ears, but has the face of one. It has short brown hair and wears a brown trench coat.

The beastman raised its hand and said something. One could argue that it said something along the line of, "Fuck yeah!".

Haruko is mesmerized by the appearance of the beastman.

"So cute…" she mutters.

Chacha stares at her fellow Maken-ki member with a look of disbelief. "Huh?"

Without a single warning, the beastman unbuttons its trench coat and shows its naked body to the two girls. Haruko gasped while blushing and partially covering her eyes with her hands.

"What on earth is that?" she demands.

Chacha, on the other hand, is very excited.

"So big! So manly!" the girl with the brown skin exclaims.

The beastman starts to move peculiarly. It's moving its body slowly in a circular motion. It only took Haruko and Chacha a few seconds to be hypnotized by its hidden ability.

While the two of them are basically rendered powelress, the door to the changing room opens, and in comes Kengo. However, this isn't the real Kengo, but actually our lingerie thief.

The thief snaps his fingers, and the beastman disappears in an instant. His face and size shifts and transforms neck to his original ones.

"It's really convenient that the two of you are together." the thief laughs creepily. "Take off each others' bra."

Upon receiving the thief's order, Haruko and Chacha turn to look at each other. And then, their hands proceeds to undress the other. The top of the idol outfit came off easily enough. Next, their hands are about to reach the straps of the others' bra.

"This will be cup number eight! All that's left are the principal and Aki-sensei!" the thief mutters to himself excitedly.

Just as the girls were about to take off each others' bras, Takeru barged in.

"Haru-nee! Chacha-senpai!" he shouts.

The first thing he sees is, of course, the four barely-concealed mountains. The sight gave him a massive nosebleed.

"What the heck is going on?" Takeru mutters to himself as he turns around and covers his nose.

"C-Can you not get in my way?" the thief demands.

Takeru glares at him.

"You! You're behind this?" he spat.

Before Takeru could go a thing, the thief snaps his fingers and summons his beastman familiar. The familiar uses a rope to tie up Takeru with a speed faster than blinking. He tries to break free, but to no avail.

"Why are you doing this? Answer me!" he demands.

"Let me answer your question with another question. Do you need a reason to take perverted pictures of women and steal their bras?" the thief asks.

"What?"

"I'm asking you whether you need a reason to live while following your instinct. You're a man too. Haven't you ever thought of doing the same thing as I have?"

"T-That's…"

The thief scoffs. "Heh, you're just a scum who's tied down by self-restrain and common sense."

He looks towards Haruko and Chacha. While he and Takeru are arguing, the two girls have taken off their bras. In other words, their huge breasts are bare. Just looking at those naked boobs caused him to have an erection.

"Hey, guess what? I was planning to dip right after I got their bra. But I think I'll go an extra mile this time." the thief tells Takeru.

"What are you talking about?"

The thief licks his tongue in a really perverted and repulsing manner.

"I'm going to take their virginity." he whispers.

Takeru's face got pale in an instant. He struggles like there's no tomorrow. Unfortunately, the rope that's used to tie him up is way too tight.

"Don't! Don't you dare! I'll kill you! I really will!" he threatens.

The thief laughs at the empty threat. "Go ahead and try. You can't even break free of a normal rope. What hope do you have?"

"Other Maken-ki members are outside! They'll come in and wipe the floor with you!"

"Oh, you mean those girls outside? I've hypnotized all of them, just like how I did these two. They won't be helping you out anytime soon."

Upon hearing that, Takeru fell into deep despair.

"Now then, who should I start with?" the thief mutters to himself.

"No, please don't…Haru-nee, Chacha-senpai…" Takeru moans.

""Haru-nee", you say?"

The thief looks at Haruko and Chacha.

"Which one of you is this Haru-nee?" he asks.

The still-hypnotized Haruko slowly raises up her hand.

"The two of you are childhood friend, or something?" he asks Takeru while smiling creepily.

"Yes. So please, don't defile her…" Takeru sobs and pleads pitifully.

"Nope. I'm going to start with her just to spite you. Come here, Haru-nee or whatever your name is."

"No, NOOOOOO!"

Haruko goes to the thief obediently.

"I'll at least make your pussy wet first. I'm not THAT heartless." the thief says to Haruko.

He reaches out his finger and begins to finger Haruko's pussy.

"Ah…ah…"

Her nipples are all stiff and erect. Her cheeks are bright red. She has a lewd expression on her face. She begins to breathe heavily. As Takeru watches helplessly, Haruko begins to pant and moan. A minute later, a sticky substance leaks out of her vagina.

She has an orgasm.

"A-Ah...!"

Haruko collapses on the floor, her body twitching and trembling.

The thief licks his lips.

"Well, let's get started."

He unzips his pants and reveals his erect penis. Then, he inserts it into Haruko's pussy.

"Ah…"

Blood came out from Haruko's pussy, signifying that her hymen had broken.

"Hmm? Oh, you were a virgin? Lucky me!"

The thief smiles victoriously at Takeru.

"How does it feel to watch your childhood friend lose her virginity to a complete stranger, eh? You must be really frustrated, you little shit! That makes me really happy! I'm gonna keep going until your precious Haru-nee can't walk anymore!"

Takeru grits his teeth and stares at the thief hatefully.

"I swear to God that I'll definitely kill you… You just watch…"

"Again, empty threat means nothing to me. Now, Haru-nee, let us have some fun, shall we? Ahahaha!"

The thief starts thrusting his hips, moving his penis in and out of Haruko's vagina. The sound of skin slapping against skin fills the room. Haruko's eyes are half-closed, her mouth is hanging open, and her tongue is sticking out. She lets out a series of incoherent moans.

"Ah...ah..."

Haruko's body trembles uncontrollably. The thief grins at her, enjoying her expression.

"You're feeling good, aren't you? I'm feeling good too. So this is what a pussy feels like! This is much better than just jerking off. I'm getting addicted to this sensation."

The thief keeps thrusting his hips, slamming his dick inside her. Blood continues to flow out from her vagina.

"Ha...ha..."

Takeru watches the scene unfold before his eyes, unable to do anything but cry. He cries and cries and cries.

"Haru-nee..."

Eventually, the thief feels that he's about to climax.

"Oh, I'm going to cum...I'm going to cum inside!" he moans.

"Don't! Don't do that! Haru-nee will get pregnant!" Takeru pleads desperately.

"Like I care!"

The thief continues to thrust his hips, fucking Haruko's pussy harder and faster.

"Ha...ha..."

He groans loudly as he reaches his climax. He ejaculates his sperm inside Haruko's pussy.

"Ah..."

Haruko lets out a small gasp.

"Hahaha! What a good feeling! Your pussy is the best, Haru-nee. It's the tightest and the warmest."

The thief removes his dick from Haruko's pussy. His cock is covered in her blood and cum. He looks at Takeru with a grin on his face.

"How does it feel to watch your childhood friend being fucked in the pussy by a random guy?"

"You fucking bastard!" Takeru yells.

The thief ignores him and turns his attention to Chacha next.

"Now, it's your turn, Chacha-senpai. You're probably really jealous, huh?"

The thief approaches her.

"Don't touch her!" Takeru demands.

"I'll fuck her as much as I want. You can't do a single thing."

The thief grabs Chacha's breasts and squeezes them roughly.

"So big and soft. These are definitely H-cup."

Chacha's body shakes. Her nipples are getting harder and harder.

"You're feeling good, aren't you? Well, I'm not surprised. Women's bodies are made for men to use, after all."

Similar to Haruko, the thief made sure to wet Chacha's pussy before fucking her. He sticks his fingers into her hole and rubs her clit.

"Ah...ah..."

Once her pussy is wet enough, the thief pushes her down and inserts his penis inside.

"Ha...ha..."

His dick slides inside her easily. He begins to thrust his hips, moving his dick in and out of her pussy.

"So...tight...you're the tightest yet!"

"Ah...ah..."

The sounds of flesh hitting flesh and moans of pleasure fill the room. The thief continues to fuck Chacha's pussy, making her orgasm several times.

"Ah...ah...ha..."

"Your pussy feels amazing, Chacha-senpai. I'm going to cum soon."

The thief increases his pace, fucking her harder and faster.

"Ha...ha..."

"I'm cumming, Chacha-senpai! Here it comes! Take it all in!"

The thief thrusts his dick deep inside her pussy and ejaculates. His cum shoots into her womb.

"Ah..."

Satisfied, the thief pulls out his penis from Chacha's pussy. He then bends down and picks up her bra, then Haruko's. He puts them inside his pants pocket.

"Now then, if you'll excuse me, I have an appointment with the principal and Aki-sensei." the thief says to the still-tied-up Takeru.

He leaves the room and closes the door behind him.

Takeru grits his teeth and clenches his fists.

"I swear...I'll kill him. I'll kill him, no matter what."

Takeru glares at the unconscious Haruko and Chacha with eyes filled with hatred.

"Haru-nee...Chacha-senpai..."

Meanwhile, the thief has already reached the principal's office and is having his way with Minori. Even the mighty principal was helpless before the thief's hypnotizing ability.

After fucking Minori and taking her bra, the thief heads over to Aki's office. There, he finds the busty school nurse sitting behind her desk.

"Good afternoon, Aki-sensei." the thief greets cheerfully.

"Oh, hello." Aki replies.

She looks up at the thief and smiles.

"Can I help you with something?" she asks.

The thief nods.

"I was wondering if you'd be willing to give me your bra."

His question made Aki go on full alert mode.

"You! You must be the underwear thief!"

"Yeah. And now I'm going to take your bra, too."

"What?!"

Before Aki could do a thing, the thief hypnotized her. Naturally, he fucked her too. He was very surprised to learn that this school nurse is actually a virgin. He enjoyed her pussy thoroughly before cumming in her. Afterwards, he took both her bra and left the room.

Having completed his mission, the thief goes back to Minori and forces her to sign a statement which enforces a new school rule. Under the rule, all boys are hereby expelled from the school, and it will return to being an all-girls one. Only two boys remained. Takeru and the underwear thief.

Takeru are to be tied up at all times. Every once in a while, he would be brought out when the thief feels like fucking Haruko.

"You're pathetic, Take-chan. You swore that you'll protect me, but you were all talk." Haruko says to Takeru with a voice full of contempt one day.

The thief laughs at what she just said.

"This is a riot! you know what's the best part here? I'm not even controlling her to say that! She meant those words out of the bottom of her heart!" he chortles.

"Shut up!" Takeru snaps. "I'm not going to let you do this! I'll never forgive you for doing this to me...to us!"

He was so furious that he almost went berserk. The thief couldn't hold himself back any longer.

"That's right! Go ahead and curse me, you worthless piece of shit! I'm not afraid! Just watch how I make your Haru-nee suffer until I get bored with her!"

The thief laughs cruelly at Takeru's reaction.

And so, the thief has officially became the true ruler of the Tenbi Academy.
