The Time I Betrayed the Busty Hero Party That Power-Harassed Me ～The Demon Lord Gave Me Land, So Now I’ll Live Free, Develop My Territory, and Punish Those SSS-Rank Bitches～ - Chapter 10 & 10.5: Crashing in on the Busty Hero Party’s Training Session | Interlude

Chapter 10: Crashing in on the Busty Hero Party’s Training Session

I had just finished breaking Marie.

Beside me, she lay unconscious—twitching, drooling, and reduced to an erotic mess. Seeing her like that filled me with a deep sense of superiority.

That was when a light knock sounded at the bedroom door.

It was Cyril.

“Good work, Lord Hyuga. Judging by the look of things, it doesn’t seem you struggled much.”

“No, no. It’s all thanks to you, Cyril.”

After all, the plan to drown Marie in aphrodisiacs until she collapsed completely—that idea had come straight from Cyril.

“Oh, right. Here, take this.”

“This is… Marie’s total slut-fall video, correct? I’ll see to it that it’s delivered to her hometown and her ex-fiancé.”

“I’m counting on you.”

With that, Marie no longer had anywhere left to run.

Judging by how thoroughly she crumbled, I doubted she’d ever recover… but still.

Accidents could happen.

Cutting off every retreat wasn’t just insurance—it was the wisest move.

“By the way, how’s Sakiel doing?”

I had entrusted Sakiel with Teresia’s punishment and Mei’s training.

I trusted her, of course, but when it came to prey, I couldn’t help but be curious.

Cyril quickly averted her eyes.

“…That’s something you should see for yourself.”

“Eh? W-What’s with that reaction?”

“…This way.”

Following Cyril, I was led down the hall to another room in the mansion.

Even before reaching the door, I could already hear voices coming from inside.

“(Hyann ♡ S-Stop it ♡ Teresiaaa ♡ Where are you even lickinggg ♡)”

“(Shut it already ♡ Just sit still and let my tongue make you feel good ♡ Every time I make you cum, I get a reward ♡)”

“(Ufufu ♡ Teresia, you’re so cute ♡ Look, look—Mei, if you want a reward too, then you’d better hold out as long as you can ♡)”

“(Ahh ♡ N-No ♡ Don’t tease my ears and tail like thaaat ♡)”

…Hmm.

So Sakiel was using Teresia to help with Mei’s training.

“There’s a part of me that really wants to see what’s behind this door.”

“Then why not take a peek?”

“No. Not yet.”

After all, when busty beauties were tangled up in an erotic mess, barging in too soon would just ruin the mood.

“(You’re surprisingly stubborn, huh ♡ Then I guess it’s time for my special move ♡ —Here we go: Charm ♡)”

“(―Hinyaaaahhh ♡♡♡♡)”

“(Nfufu ♡ So? Did you fall for me now ♡)”

“(Ahh ♡ N-No ♡ Y-Yeah, I love you ♡ N-No, wait ♡ That’s not how I really feel—ahhhhnnn ♡)”

“(C’mon, c’mon ♡ Fall in love with meee ♡ Double Charm cast ♡)”

Charm, huh.

If I remembered right, that was a spell that bent someone’s will to your own—a succubus specialty.

Wait a second…

“Cyril, doesn’t Charm normally not work on the same sex?”

“Correct. Normally, Charm has no effect on those of the same gender. However, Lady Sakiel’s version is a little different. She weakened the brainwashing aspect in exchange for making it effective on women as well.”

“…Does that even make sense?”

“Not really, no. But Lady Sakiel herself is the kind of woman whose every gesture makes others fall for her. To borrow Lord Ark’s words—she’s basically a ‘mass-producer of diehard fangirls.’”

Ark, what kind of ridiculous term are you spreading around?

Still… it was dead-on. Sakiel really did have that kind of irresistible charm you couldn’t tear your eyes away from.

“…Honestly, I’m amazed I actually managed to make Sakiel my wife.”

“Indeed. By the way, Lord Hyuga, you’re quite famous for being the only man who ever won Lady Sakiel’s heart. Among her fangirls, there are even some who wish you dead.”

“Eh!? Wait, what the hell!? That’s the first I’m hearing of this!”

“Please don’t worry. His Majesty the Demon Lord has already ensured that such types are kept under control.”

“…Seriously, Ark, you’re the real MVP.”

Ever since betraying the busty hero party, Ark had been helping me nonstop.

Getting this much support honestly made me feel a little guilty.

“…Guess I should try to repay him somehow.”

“There’s no need. This is simply His Majesty’s way of repaying a debt.”

“Repaying a debt?”

“Because of you, Hero Lunatia lost her power as a hero. His Majesty the Demon Lord is deeply grateful for that.”

“R-Really? But come on, it’s Ark we’re talking about—he probably could’ve handled it without me betraying them…”

“No. Not necessarily.”

Cyril shook her head firmly from side to side.

“The Demon Lord can never truly defeat a Hero. That is simply the law of this world.”

“…The law?”

“Yes. Even if His Majesty the Demon Lord holds overwhelming strength, at the crucial moment the Hero’s true power will suddenly awaken and—boom. If you hadn’t switched sides, Lord Hyuga, His Majesty most likely would have lost.”

Ehh… what the hell.

So it was basically a forced loss event?

But thinking back, when we faced Ark in the Demon Lord’s castle, I really did feel something heavy from him—an oppressive aura.

Maybe that had been the nerves of a man who already knew he was doomed to die.

“So, there’s no need for you to feel indebted. ―In fact, if you ever thought of repayment, His Majesty asked me to tell you directly not to worry about it.”

“…O-Ohh. Got it.”

Well, in that case, guess I’ll just drop the whole ‘repayment’ idea.

“Still, Cyril, can you at least tell Ark this for me?—‘If you ever run into trouble, I’ll lend a hand anytime.’”

“Understood. …By the way, it seems the room has gone quiet.”

“…You’re right.”

I carefully cracked the door open to peek inside.

And there it was—Mei and Teresia, both with their faces buried in Sakiel’s massive tits.

“Ahh ♡ Darlinggg ♡ Look, look ♡ Mei’s completely docile now ♡”

“Nyaaaan ♡ Nyan-nyan ♡”

“Not fairrr ♡ I want a reward toooo ♡”

“Ahn ♡ Geez ♡ Such greedy little pets you two are ♡”

The sight was magnificent.

Even if their personalities were trash, seeing Teresia and Mei—both absurdly gorgeous—tangled up with Sakiel was nothing short of bliss.

And yet…

“Hey, you two. Sakiel’s my woman, you know.”

Seeing Teresia and Mei clinging all over Sakiel while completely ignoring me really ticked me off.

So I activated my ancient magic—Big Daddy.

Interlude: The Busty Hero Party’s Cat Finally Shows Her True Colors

Beastkin normally couldn’t use magic.

But that didn’t mean beastkin were weaker than elves or humans who could.

In fact, beastkin possessed physical abilities that far surpassed most other races.

Even so, when I was little, my body had always been frail.

Because of that, I grew up constantly looked down on.

“A sickly beastkin… how pathetic.”

“Might as well sell her off as a slave.”

“True, Mei’s got a pretty face. She’d fetch a high price from some human with a thing for little girls.”

“Hey, don’t joke about that.”

I wanted strength.

I couldn’t stand being despised just because of the body I was born with.

That was when I set my eyes on magic.

An elf adventurer who passed through my village happened to use it.

With magic, I thought, even I could fight.

So while everyone kept mocking me as weak, I worked hard, scraping together the money to enter a magic academy.

But then…

“A beastkin using magic? Don’t make me laugh.”

“Give it up and go back to the animal shed where you belong.”

“Let me teach you your place.”

After five long years of saving money, I finally enrolled in the magic academy.

What awaited me there, though, was nothing but ridicule and violence.

They had all decided on their own that a beastkin could never wield magic.

Fortunately, it turned out I possessed overwhelming magical power—greater even than the elves.

I shut them up with sheer ability.

For the first time, I forced the world to acknowledge me through my own strength.

That feeling was intoxicating.

From then on, I carried absolute confidence in both my talent and my hard work.

Eventually, I graduated at the very top of the academy and joined the hero party.

But annoyingly enough, every single member of that party turned out to be a genuine prodigy.

The Hero was royalty—an elite among elites, raised under strict training from childhood.

The dragon princess was a natural-born powerhouse, arrogant and greedy to the core.

And the elf saint was such a frustratingly good-hearted girl it almost made me sick.

All of it dragged up my old feelings of inferiority.

So I threw myself into training—harder and harder, pushing beyond every limit.

And then it happened.

The man from another world appeared.

The one who had deciphered the ancient magic no one else had ever been able to.

“N-Nice to meet you. From today, I’ll be in your care. I’m Hyuga. Please treat me well.”

That pissed me off.

Even though he had done something incredible—deciphering ancient magic no one else could—he stood there with no confidence, acting all timid.

It irritated the hell out of me.

So I bullied him relentlessly.

But in the end, it came back around, and we—I—were the ones betrayed.

He cast that ancient magic, the kind that made it impossible to resist the caster’s will, and locked us up like livestock in a cramped little room.

Then I found out maybe one of us had leaked information.

That really pissed me off.

Especially Teresia.

So I decided that when she came back, I’d punch her once, then let her punch me back.

After that, we could apologize, trade blows, and make up.

…But instead—

“Nice to meet youuu ♡ I’m Sakiel ♡ Just recently became my darling’s wife ♡”

“H-Hah!? Who the hell are you—wait, Teresia!?”

Led there by that damn succubus, what I saw was Teresia—completely changed.

That selfish, free-spirited dragon princess was nowhere to be found.

Instead, she was crawling on all fours like a horse, carrying an unbelievably cute girl—so cute even I couldn’t look away—on her back.

The girl introduced herself as Sakiel.

“H-Hey, you!! Get off of Teresia right now!!”

“Fool!! Do not interrupt my moment of bliss!!”

“W-What the hell are you even saying, Teresia—”

“Nfufu ♡ Teresia is already our pet now ♡ There, there, good girl ♡”

“Hyaaan ♡ My ladyyy ♡”

Teresia moaned as Sakiel stroked her ass.

I couldn’t believe what I was seeing, and before I knew it, I shouted:

“Y-You’ve gotta be kidding me!! What the hell did you do to Teresia!?”

“You dare show such rudeness to my lord’s wife!? I pledged loyalty to my lord of my own free will, and Lady Sakiel personally trained me!!”

“W-Wait… by lord, you mean him!?”

The sight of Teresia—who once fought at my side—now calling that bastard lord shook me to the core.

“Nfufu ♡ Don’t worryyy ♡ You’ll be joining us soon enough ♡”

“Rejoice, Mei ♡ Lady Sakiel herself will personally train you so you can become Master’s pet too ♡”

“S-Stop it, let go of me!!”

“Don’t struggle so much ♡ Lady Sakiel’s fingers feel heavenly, don’t they ♡”

From there, they made me feel so good it drove me insane.

Toyed with by Sakiel and Teresia, my body melted, my mind scrambled, until I started confusing it all with happiness itself.

And before I realized it—

“Nyaaaan ♡ Nyan-nyan ♡”

—I was mewling like a cat, having forgotten human words, desperately fawning over Sakiel.

Ahh… what humiliation.

And yet, strangely, there was no disgust.

Deep down, I understood why.

I was a pet now.

A pet was naturally beneath humans—there was no reason to feel shame in that.

No more scorn, no more ridicule.

Just being spoiled, cherished, and treated like a beloved animal.

“Hey, you two. Sakiel’s my woman.”

The one who walked into the room was the man I once hated more than anyone.

And yet… for some reason—

The moment I saw him, I spun around without hesitation, lifted my ass, and shook my hips for him.

“Nyan ♡ Nyan-nyan ♡”

“Huh? W-What the hell are you doing?”

“Ufufu ♡ I drilled it deep into her head that you’re her Master ♡ Now she’s begging for your seed ♡”

“Nyaaan ♡”

“…You horny cat. If you’d shown that attitude from the start, maybe you wouldn’t have gone through all this!!”

Smack!

After slapping my ass hard, that man—my Master—ravished me thoroughly.

And it felt amazing.

I even managed to make up with Teresia, and later, when I reunited with Marie, she had already been through the same fate as me.

If we were all pets together, then there was no reason to be jealous of my talented comrades anymore.

Ahh, that’s right.

It wouldn’t be fair for just one of us to be left out.

We’d have to bring Lunatia in too—make her our companion, our fellow pet.
