[Volume 1 Prologue] When I confessed to the girl I liked, her twin sister came along as a bonus

Prologue

My girlfriend is a twin.

What would people think when they hear this?

I can’t know what others might think, but as a sensible guy, let me share my perspective.

In other words, wouldn’t most people assume that my girlfriend has a twin sister or brother?

Twins are rare, but it’s not exactly shocking news.

However, in my case, it is shocking news.

“Masaki, you’re leaning a bit too much toward Fuuka, don’t you think?”

“Ehh, it’s fine, isn’t it? I’ll let Yuzu-nee have her turn later.”

“…”

A high ceiling, a spacious living room meticulously arranged with a sofa, table, and TV—clearly coordinated by a professional.

Sunlight streams through the large windows, offering a panoramic view of the city stretching far into the distance.

This is the top floor of a certain luxury tower mansion.

A blatant symbol of wealth, reserved only for the chosen few.

Normally, a commoner like me, through and through, would be turned away at the entrance.

Yet here I am, sinking into a lavish sofa that costs 400,000 yen, and on top of that—

“Well, whatever. I’ll just snuggle up to you instead.”

“Haa, this really does feel calming, doesn’t it?”

I’m seated in the center of the sofa, flanked by two girls on either side.

Two girls with identical faces—twins, in other words.

The older sister, Tsubasa Yukizuki.

The younger sister, Tsubasa Fuuka.

Their faces are exactly the same—strikingly beautiful, with large, captivating eyes.

The Tsubasa sisters are twins, and not just any twins, but breathtakingly gorgeous ones.

Yukizuki has long, brown hair, wearing a short-sleeved blouse and a miniskirt.

Fuuka has long, black hair, dressed in a sleeveless knit top and a knee-length skirt.

Their hairstyles and outfits are the only things that barely distinguish them. If you looked only at their faces, you’d never tell them apart.

“Masaki-san, your hands are idle.”

“Yeah, yeah, you gotta be more shameless! This is boring otherwise.”

“Shameless, huh…?”

In this extravagant room, on this extravagant sofa, I’m flanked by twin beauties—

It’s an absurdly privileged situation, yet they’re telling me to demand more happiness?

“Alright, this is what you want, right?!”

““Kyaa! ♡””

The twins let out a synchronized squeal.

Normally, their speech patterns differ, but every now and then, they sync up like this, letting out adorable cries that are just unfair.

I flip up Yukizuki’s short skirt and firmly grab her backside.

A soft, yet firm sensation spreads through my hand, indescribably perfect.

In my haste, my fingers slip slightly into her underwear, but there’s no pulling back now.

With my other arm, I slide my hand under Fuuka’s white knit top, grasping her massive—90-centimeter—chest over her bra.

It’s a different sensation from her backside, but even through her underwear, the softness and elasticity are overwhelming, her sheer volume too much for my large hand to contain.

“Ah… Masaki-san, your hands are so naughty…”

“Grabbing both flowers at once, what a greedy guy…”

“You’re the ones who told me to do it!”

“Okay, okay, my bad. Here’s an apology—chu! ♡”

“Sorry, sorry. My apology—chu! ♡”

As I protest, the twins lean in at the exact same moment, planting kisses on my cheeks.

Groping the bodies of twin beauties while being kissed by both at the same time.

Even now, I can’t help but wonder if this is a dream—or some kind of delusion.

A sweet fragrance wafts from them, their slender yet impossibly soft bodies pressing against me, their giggling voices syrupy and soothing to the ears.

“You still look like you can’t believe this, huh, Masaki?”

Yukizuki pokes at my cheek with a teasing tsun tsun.

“I get it, though. Even we never dreamed we’d both end up dating the same guy.”

“Dating both twins at once? That’s straight out of a fantasy.”

“And you two are the ones Masaking that fantasy reality?”

“Sure, sure. You can think of it as a dream if you want. Might make you more motivated, right?”

“Exactly. This is a dream. So, enjoy us to your heart’s content, okay?”

Yukizuki and Fuuka cling to me, showering my cheeks and forehead with chu chu kisses.

I stroke Yukizuki’s backside over her underwear, kneading Fuuka’s chest with a guni guni—

“If it’s a dream, then fine…”

I put more strength into my hands, indulging in their bodies further.

Their bodies are unbelievably soft, the lips pressing against me feel divine.

“That’s it, that’s the spirit. We’re—two as one.”

“But—one as two, too.”

Two twins who are one.

I kind of get what they mean, but—

One as two? At first, I had no idea what that was supposed to mean.

But these twins have a peculiar trait.

Yukizuki is Yukizuki, but also Fuuka.

Fuuka is Fuuka, but also Yukizuki.

Yeah, explaining it like this probably makes no sense to anyone else.

But the reason I’m being overwhelmed by these twins—and overwhelming them in return—

It’s because they’re a special kind of twins: Dual Twins.

“What’re you zoning out for? Come on, if you’re not coming to us, we’re coming to you!”

“We’re coming for you!”

“Like I’ll let you two take the lead… Alright, here I go!”

““Kyaa!””

I pull the squealing, delighted twins closer, slipping my hand under Fuuka’s knee-length skirt to caress her thighs—

And shoving my hand into Yukizuki’s blouse, kneading her chest with a guni guni.

Their bodies are identical, not just in appearance but in their elasticity.

Even they themselves probably don’t realize it.

While fondling Yukizuki’s chest, I slide my hand further to stroke her smooth stomach.

My hand on Fuuka’s thigh creeps upward, grasping and kneading her backside.

This is unreal—if this is a delusion, I never want to wake up.

With that wish in my heart, I let my mind drift back to a memory from just a few days ago.
