Little Sister, Don't Use Me as Your Fap Material! ~Operation to Capture the Perverted Brother-Sister's Special Fetish Girl~ - Chapter 10: The Shoe Locker Is Mine

Chapter 10: The Shoe Locker Is Mine

“Sensei~, I’m not feeling well. Can I go rest in the infirmary for a bit?”

『What’s this, Aoyama? Is my Japanese History class so boring that you want to skip it?』

Mr. Okabe dramatically overreacted in a joking tone.

“Ah, no, it’s not that… My head…”

『Hurts?』

The whole classroom burst into laughter.

The fact that such a low-level exchange could generate this much laughter really shows how ridiculously low high school students’ humor threshold is.

“My head hurts.”

『I see. Alright, I’ll allow it. However, I won’t tolerate you secretly using the infirmary tissues for improper purposes.』

“I won’t use them!”

Once again, the classroom erupted in laughter.

『Also, just so you know, your beloved Yakushiji-sensei is absent today. Too bad.』

“Ehh~ Misako-chan isn’t here~? Then maybe I won’t go after all~ lol”

……Silence.

Hey, it was a joke, everyone. Please laugh.

“Gross…”

Natsuki’s quiet mutter from the back of the room echoed sadly in the now-silent classroom.

※ ※ ※ ※ ※ ※

The real reason I skipped Japanese History class wasn’t to waste the infirmary’s tissues on masturbation, nor was it to visit the beautiful 32-year-old school nurse overflowing with adult charm.

In fact, I wasn’t even heading to the infirmary at all.

I had come to the shoe lockers — the place where all the students’ shoes are stored.

My target was Midorigawa Kaede’s shoe locker.

While everyone was in class, I planned to secretly attach the GPS Madoka had given me to the sole of her school-designated loafers.

Since I had memorized the student ID numbers of all the beautiful girls in my grade, I had no trouble finding Midorigawa’s locker.

*

Click.

When I opened the locker, there they were — Midorigawa Kaede’s beloved loafers.

I picked them up, brought the opening to my nose, and took a deep sniff.

Sniff sniff, sniff sniff.

Ohhh♡ What a wonderfully fragrant scent♡

This smell could only be described as “the scent of a beautiful JK’s loafers worn down through daily school life”♡

Sniff sniff. Sniff sniff.

Aah… I’m currently enjoying the scent that Midorigawa Kaede probably wouldn’t want anyone to smell… Dehehe♡

This is bad… I’m getting really turned on…

I pulled the loafer away from my nose, then couldn’t resist planting kisses on the toe area.

Chu♡ Chu♡ Chu♡

Right now, I’m kissing Midorigawa Kaede’s feet… Dehehe♡

Next, I stuck out my tongue and licked the surface of the cowhide.

Lick lick, lick lick.

Aah~♡ Licking Midorigawa’s shoes… I’m so happy♡

Lick lick, lick lick.

Fuhihi♡ Kaede-chan’s feet taste so good♡

*

Wait, no, no. I almost forgot my original purpose.

I came here to attach the GPS to Midorigawa’s loafers.

…But before that, maybe I can enjoy myself just a little more♡

Still holding her loafer, I dashed into a stall in the boys’ bathroom.

I loosened my belt, pulled down my pants and underwear, and sat on the Western-style toilet.

Once again, I pressed the opening of Midorigawa’s loafer to my nose and took deep breaths.

Suuu~ Suuu~ Suuu~ Suuu~

The stimulating scent filled my nostrils, causing an immediate “male” reaction in my lower region.

Throb throb throb— Ping!

To think I’d get fully erect just from the smell of a school beauty’s loafers… What a profoundly sinful libido I have.

Even while thinking that, my right hand began stroking my cock.

Stroke stroke stroke stroke.

Midorigawa, Midorigawa, Midorigawa♡

While everyone else is studying, I skipped class using a fake illness and am now secretly masturbating while sniffing Midorigawa’s “embarrassing scent.”

This is insane! This immoral feeling is making my brain go numb!!!

Stroke stroke stroke stroke.

As the urge to cum grew stronger, my right hand moved faster.

Ah, aah, I’m gonna shoot!

I’m cumming from the smell of Midorigawa’s loafers!

Right before climax, I moved the opening of the loafer directly into the line of fire of my cock.

Stroke stroke stroke stroke.

“Ugh, Midorigawa!♡”

Splurt! Splurt splurt splurt!! Splurt…

Thick, sticky semen shot out from my cock and splattered inside Midorigawa’s loafer.

The insole, soaked with her scent, was now stained and defiled by my “white.”

Haa~ That felt great!

As expected, “immorality” is the best spice for masturbation!

……Wait, I got completely carried away by my desires and did it!!!

What the hell do I do about the cleanup…?

*

For now, I need to destroy the evidence…

Damn it. Even if I wash the insole, there’s no way it’ll dry before school ends.

Is there any clever way to handle this?

I looked over Midorigawa’s loafer.

Hmm… Size 25.5 cm. Same as Madoka…

Same as Madoka… That’s it!

I left the boys’ bathroom and headed back to the shoe lockers.

“Let’s see, Madoka’s locker should be… Ah, here it is!”

I opened Madoka’s locker. Inside were her own pair of 25.5 cm loafers.

I picked them up and gave them a quick sniff.

Sniff sniff.

Oh, surprisingly, they don’t smell as strong as Midorigawa’s.

…Ah, that makes sense. Madoka has only been wearing them for about a month, so the scent is still light.

After confirming the scent, I pulled out the insole from Madoka’s loafer and swapped it with the insole from Midorigawa’s loafer.

Then, I returned both pairs of loafers to their respective lockers.

Phew~ That was close. Camouflage operation successfully completed…

Oh right, I almost forgot the original mission.

I took out Midorigawa’s loafer again and used instant glue to attach the GPS chip to the arch area on the sole.

Alright, mission complete for now.

*

There’s still some time left before class ends…

Might as well enjoy the scent of other beautiful girls’ loafers while I’m at it.

Emergency event decided!

【Doki♡ Beautiful Girls’ Loafer Scent Contest】

Now, in what order should I enjoy them?

Logically, it should be Momose from the tea ceremony club, Mizukami from the swimming club, and then Tosaka the student council president.

Wait, maybe Kurabayashi, the school’s top gal, would be good too…

No, I should show some respect to my childhood friend first.

I headed to Natsuki’s locker and took out her loafers.

Sniff sniff.

Ooh~ This one has a much stronger scent than Midorigawa’s♡

*

“Aoyama-kun, what are you doing over there?”

Suddenly called from behind, I quickly shoved Natsuki’s loafers back into the locker in surprise.

“C-Committee President…? What are you doing here…”

The person standing there when I turned around was Shirakawa Nozomi, the class committee president of my class.

Yes — she was none other than the rumored “black T-back pigtail committee president.”

“I was a little worried about you, Aoyama-kun, so I was thinking of stopping by the infirmary. On the way, I happened to see you… By the way, the locker you just opened was Natsuki-chan’s, right? What exactly were you doing?”

Shit. I got caught doing something weird.

I need to come up with an excuse, fast.

“About the reason I said I wasn’t feeling well earlier… ‘My head hurts’ was actually a lie. The truth is, I’m suffering from ‘lovesickness’…”

“Lovesickness? Don’t tell me the person is…”

“It is. The person is my childhood friend, Natsuki. My feelings for her have reached the breaking point, so right now I was just about to put a love letter in her locker.”

Even I’m impressed at how smoothly I can spout such convenient lies.

Well, since she’s such a serious committee president, she probably won’t pry too deeply into someone’s love life.

“A love letter!!! How old-fashioned! But that actually makes it even more wonderful!!! I think Natsuki-chan would like that kind of thing too. I’m totally in favor of it!!!”

Shirakawa leaned forward excitedly, stepping closer and closer.

Her eyes were sparkling brightly.

Ah, so the committee president actually loves this kind of sappy topic.

*

“So, what kind of love letter did you write, Aoyama-kun? If you want, I can proofread it for you to increase your success rate!”

Not only is she not staying out of it, she’s being overly helpful.

I’ve never heard of someone offering to proofread a love letter.

“No, no… Having the top student in the grade proofread my love letter is just… Actually, I haven’t written it yet…”

“If you haven’t written it yet, that’s even better! I’ll help you compose it right here! Yes, let’s do it!”

“But I don’t have any paper or pen…”

“Here. Stationery and a pen. I came prepared just in case.”

What kind of future foresight is this?

Don’t tell me she’s also a superpowered person…

*

“Okay, let’s start writing right away!”

“Y-You’re really doing this?”

“Of course! Come on, stop talking and start moving your hand!”

The committee president is surprisingly strict…

Under her passionate guidance, I wrote a love letter to Natsuki.

“You should use more passionate expressions! Natsuki-chan is definitely weak to that kind of ‘push’!”

“Y-Yes, understood!”

“Let’s cut the past episode talk here. It makes the letter too long, and more importantly, what matters isn’t the past — it’s the present! Be direct with your current feelings!”

“You’re right, Shirakawa-sensei!”

“Aoyama-kun, what do you like about Natsuki-chan?”

“Um… I like her cute face…”

“Uh-huh, what else?”

“I like how her ponytail suits her, how she’s actually kind, how she has no hidden side to her personality, and above all, her smile is adorable… Wait, I think I love everything about Natsuki. What should I do, Sensei?”

“Just write it all down!”

“Is that really okay?”

“Yes, write everything! Put all your feelings into that letter!”

“Yes! I’ll pour all my feelings into this letter and deliver them to her!”

And so, with the committee president’s enthusiastic help, I completed a passionate love letter.

I immediately slipped the freshly written letter into Natsuki’s shoe locker.

Phew~ With this, today’s mission is complete!

…Wait, why did I end up writing a love letter to Natsuki?

“Aoyama-kun, I’m glad it turned out to be such a good letter! No matter the result, I’m sure your feelings will reach Natsuki-chan!”

…Well, the committee president looks happy, so let’s call it a win.

※ ※ ※ ※ ※ ※

After school, I waited near Madoka’s shoe locker to report that the GPS had been successfully attached.

“Onii-chan, sorry for the wait~”

Madoka soon arrived.

When she opened her locker to take out her loafers…

“Uwaa, it stinks! What the hell!? Why does my shoe locker smell like Onii-chan’s semen!? Bleh!”

Well, yeah… if you leave it unwashed, that’s what happens…

Even Madoka seemed genuinely angry this time.

“Ohhh♡ My shoe locker smells like Onii-chan’s cum… That’s actually the best!!!♡ Every time I go to and from school, my pussy is gonna get wet!♡ Sniff sniff♡ It stinks♡ This is bad, I think I’m getting addicted♡ Aah~ I wanna go home and finger my pussy right now♡♡♡”

It seems that once this girl gets horny, her rationality completely flies out the window and her perversion reaches new heights.

…Well, she looks happy, so let’s call it a win.

※ ※ ※ ※ ※ ※

In my room after taking a bath.

Just as I was about to jerk off to Madoka as I had sworn this morning, I received a rare RINE message from Natsuki.

Wondering what it was about, I nervously opened the chat, thinking it might be about the love letter.

『I read the letter.』

『Yeah.』

『I wanted to say it’s gross, but… honestly, I was a little happy.』

『I see.』

For real!? Natsuki actually softened toward me!?

The committee president’s ghostwriting skills are terrifying… She managed to move the heart of this embodiment of lookism…

『But I’m sorry. Like I said before, I like Tachibana-kun, so I can’t respond to your feelings.』

『Yeah, I already knew that.』

Of course I knew there was no chance.

『If you knew, then why did you write a love letter?』

Honestly, the whole situation was force majeure…

Still, I was the one who wrote it, and the contents were undoubtedly my true feelings.

Above all, I don’t regret it at all.

『It’s fine. I just wanted to write it.』

『Hmm~』

Ping♪

Hm? Natsuki sent me a photo.

『This is a photo from when I went to the beach with friends last year. Cute, right?』

Natsuki in a bikini!!!

She looks insanely cute and ridiculously erotic!

This is dangerous! A bikini photo of my beautiful JK childhood friend is a lifetime treasure of fap material!

『So? What do you think?』

『Extremely cute♡ Thank you so much♡ I’ll make it a family heirloom of the Aoyama household!!!』

『You’re welcome.』

『But why did you send me this photo?』

Don’t tell me she actually has a hidden desire to be used as fap material by a gross guy?

『No particular reason. Just a whim.』

『I see. Then I’ll make good use of it tonight♡ Dehehe♡』

『Gross! Stop reporting every single thing!』

The next morning, while pouring sauce on her fried egg, my little sister said:

“Onii-chan, last night you jerked off to Natsuki-chan again, didn’t you…”

…Sorry, little sister.

Your brother’s oath was shattered by your childhood friend’s bikini photo…
