Little Sister, Don't Use Me as Your Fap Material! ~Operation to Capture the Perverted Brother-Sister's Special Fetish Girl~ - Chapter 3: When the Little Sister Moans

Chapter 3: When the Little Sister Moans

On the way home from karaoke.

There’s no moonlight due to the new moon, and the surroundings are dimly lit.

The time is a little past 8 PM.

Even though it was a weekday, the karaoke place was unexpectedly packed, so our “free time plan” that was supposed to be valid until 10 PM got cut short after only 3 hours from entry. As a result, our “Virgin Alliance” ended up heading home two hours earlier than planned.

『Man~ Even so, today’s karaoke was especially hype~』

“Yeah, you really can’t beat having fellow virgin buddies.”

『Kazuya, you’re surprisingly good at singing. It’s like your soul was in it — the “passion” you put into those one-sided love songs was insane.』

“What do you mean ‘surprisingly’? It doesn’t matter if an ugly guy can sing well.”

『Wait, don’t tell me… are you in the middle of a serious one-sided crush?』

“Nope.”

『It’s gotta be that childhood friend, Akazaki, right? I get how you feel, but she’s way out of our league — a “flower on a high peak.” I’m telling you, sometimes you just gotta know when to give up in life, Kazuya.』

“I already told you it’s not her. Besides, you’re not in any position to lecture me.”

*

…“One-sided love,” huh.

Yes. Right now, I have someone I’m in love with.

That person isn’t exactly on a high peak, but between the two of us, there exists a “wall that cannot be crossed.”

…More accurately, a “wall that must not be crossed.”

This love that can never be fulfilled.

This love that must never be fulfilled.

If God really exists, I’d like Him to tell me exactly what awaits at the end of this foolish older brother’s lost and drifting “feelings.”

…No, maybe it’s better not to know.

This world is full of things you’re better off not knowing.

That’s probably true for “this” as well…

*

Come to think of it, I forgot to tell that “princess” that the prince’s triumphant return was coming earlier than expected.

She did say she was going out after school too, but I wonder if she’s already back home?

While thinking about such things, I arrived in front of our house.

『Oh, this is your place, right Kazuya?』

“Yeah.”

A completely ordinary single-family home in a quiet residential area, with a nameplate that reads 【Aoyama】 on it.

Only the light in my second-floor room is on.

Huh? That’s strange… I’m sure I turned off the lights before leaving this morning…

Ah, I see. Madoka is probably in my room again, reading manga without permission.

I’ve told her so many times to take them back to her own room if she wants to read them, but it seems my pleas as her older brother continue to be rejected.

*

『See ya, Kazuya.』 『Later.』 『Good night~』

“Yeah.”

After seeing off my virgin friends, I unlock the door and open it.

Madoka’s shoes… are here.

Looks like she’s already back home.

Ah, this is it.

The older brother returns home earlier than planned to a house where he lives alone with his little sister at night.

Which means……

This is a confirmed Lucky Pervert Event flag!!!

*

Earlier I was spouting sentimental poetry, but honestly, the worries of a pubescent boy can be blown away by just one or two erotic events.

Useless “feelings” with nowhere to go can be solved by shooting them out with semen into a tissue, wrapping it up, and tossing it in the trash.

“Lewdness” is what truly reigns supreme over everything in this world.

Little sister, become my fap material, become the outlet for this pent-up lust, and comfort your older brother’s “feelings.”

*

Alright then, let’s go hunt for that Lucky Pervert moment!

Emergency Quest: 【Obtain Tonight’s Fap Material at the Aoyama House at Night】 — Start!

…Damn it. No matter how hard I look in the corners of my vision, I can’t see a save icon.

That means no mistakes are allowed…

*

First, I quietly killed my presence and headed toward the most promising location in the house: the changing room.

I thought she might be in my room, but that was probably a bluff…

A devilish red herring meant to make me waste this once-in-a-lifetime chance.

After all, her blazer and pleated skirt were carelessly thrown on the living room sofa.

The real main event has to be an accidental encounter with my freshly bathed little sister in the changing room! That’s it! It has to be!

The day has finally come where I get to experience a real-life “Kyaa! Onii-chan, you pervert!” moment!

With this, today’s fap material RTA will be successfully completed.

Now, let me feast my eyes on those beautiful raw breasts that were raised just to be ogled by your brother!

F-cups, come to me!

Slide.

*

…Huh? She’s not here?

That’s weird~ All the classic event flags were set, and my dick was rock hard too.

Which means… she’s probably just holed up in my room as usual…

She’s either reading manga or playing games.

Honestly, I already knew. Getting my hopes up was pointless.

Reality is cruel. Even when living alone with your little sister, Lucky Pervert events don’t happen so easily.

*

However…

However.

It would be boring to just back down now.

Seeing my little sister’s panties while she’s lying on the bed reading manga is already part of my daily life as her brother.

As her older brother, I get to see my little sister’s panties whenever I want.

Not that I’ve ever gotten tired of it, though.

*

Hmm… So what should I do now…?

How can I steer things from here into a Lucky Pervert development?

Maybe in this day and age, erotic events don’t trigger unless you pay up?

Haa… What a harsh world we live in…

After that, I tried unusually hard to come up with a clever idea, but of course nothing good came to mind…

Not doing anything with this opportunity felt frustrating, so I decided to at least surprise my little sister and vent some stress.

A brother is a creature that can take out his frustrations on his little sister as naturally as breathing.

*

I merged with the surrounding air to erase my presence, held my breath, went up to the second floor, and placed my hand on my room’s doorknob.

…Hm?

I can hear some kind of “sound” leaking from inside the room.

『……Ah… Ahn… Ah… Ahn…』

What? A girl’s voice?

And it sounds like… moaning.

Ah!!!

Don’t tell me Madoka is secretly watching my treasured AV collection!

Damn it, I told her so many times not to watch them without permission.

In that case, I have no choice but to punish her for violating the non-aggression treaty as a caught red-handed offender.

The punishment should be… yeah, “dishwashing duty for one week” sounds fair.

Alright, time to barge in…

I slowly turn the doorknob down to its limit, then stop.

This way, I can open the door without making a sound.

Ssh.

Along with a faint movement of air that only I could hear, a small gap is created.

And on the other side of the light streaming through that gap…

There she was — my little sister.

But in a form that greatly betrayed my expectations.

*

…… …… ……

I was speechless.

No words came out.

It wasn’t just because the scene before me was incredibly shocking.

Well, that was part of it, of course.

More than anything, I was simply, purely, and completely captivated by the sight of her.

I was so mesmerized that I lost all words.

There are countless things in this world you’re better off not knowing.

Even if what was happening before me was one of those things, I couldn’t look away.

*

On my bed, in my room.

With her firm F-cup breasts fully exposed.

Pressing a white clump — most likely one of my used tissues — against her nose with her left hand.

A girl violently fingering her own pussy with the fingers of her right hand.

“Nn… Ah… Ahn… Ah♡ Oh no♡ I’m gonna cum! I’m cumming! I’m cuuumming♡”

“Oh♡ Shit♡ Ohh! Ohh♡ Cumming! I’m cumming!! Ooooh♡♡♡ Onii-chan♡ I love you♡ I love you so much♡”

There was no mistaking it.

It was unmistakably my real little sister — Aoyama Madoka.

*

This is the story of a little sister who encountered the uroboros known as “pleasure,” became enchanted by it, and beautifully went mad.

It is the tale of a foolish brother and sister who overlaid “love” onto a gentle yet fleeting “phantom.”
