Little Sister, Don't Use Me as Your Fap Material! ~Operation to Capture the Perverted Brother-Sister's Special Fetish Girl~ - Chapter 16: You Are the Merciless Naked Queen (Part 2)

Chapter 16: You Are the Merciless Naked Queen (Part 2)

What the hell is Midorigawa doing!?

“Good evening♡ Kaede-chan is currently completely naked on the rooftop of some random building~♡ Yay♡”

Fully naked, she struck exaggerated “cutesy poses” toward her own smartphone camera that she had set up.

There was zero trace of the talented, elegant, number-one beauty of Eguchi Sugi Academy that I knew. Aside from her appearance, she seemed like a completely different person.

Her transformation was so drastic that I could easily believe she had a split personality.

“My boobs~ My ass~ And even down there~ It’s all completely visible~♡ Ahaha♡”

She smiled brightly at the camera and actively showed off every part of her body.

She’s filming herself doing outdoor full-nude exhibitionism!?

“The reason Kaede-chan is naked in a place like this is because she’s a huge perverted exhibitionist girl~♡ Kyapi♡”

She winked and did a gal-style peace sign at the camera, looking genuinely happy from the bottom of her heart.

Her smile was more lively and radiant than any expression I had ever seen from Midorigawa before.

Rather than being shocked by the outdoor exhibitionism itself, I was far more shocked that the serious, perfect Midorigawa Kaede was behaving in such a brainless, stupid way.

Bathed in the pale blue light, her current state felt so surreal that I almost felt like I was having a waking dream.

*

“Onii-chan, does this mean Midorigawa-san is doing a live exhibition stream?”

“No, that’s impossible. She’s not streaming live.”

“How can you be so sure?”

“If a girl as insanely beautiful as Midorigawa — the ‘once in a thousand years’ type — started doing outdoor exhibition streams, it would cause an absolute uproar. The ‘Fap Hunter Association’ would never stay silent.”

“Fap Hunter Association?”

“It’s an online organization made up of volunteers — ‘gentlemen’ from all over Japan. They gather the latest information on fap material 24/7. The fact that even I, a ‘Pro Fap Hunter’ within the association, have never heard of a ‘Kaede-chan’ live stream is proof enough that she isn’t streaming.”

“But maybe this is her first time?”

“If a ridiculously lewd girl with massive areolas started doing an erotic live stream right now, the association headquarters would immediately send out a ‘Level 5’ emergency alert to all hunters. There’s been no such movement. Therefore, Kaede-chan is not broadcasting to the public.”

“I see… By the way, as a Pro Fap Hunter, what do you think would happen if ‘Kaede-chan’ actually started a live stream?”

“…Unfortunately, I estimate that roughly half the world’s population would die.”

“The scale of the butterfly effect is insane!? This world would collapse from just one flick of Midorigawa-san’s finger!?”

“If only her areolas were one centimeter smaller…”

“Is the balance of the entire world that fragile!?”

*

“Midorigawa is probably just recording selfie videos for personal use and keeping them to herself.”

“Why would she do something like that?”

“Who knows? Only that exhibitionist slut herself knows the answer.”

“Maybe she gets off harder when she films herself masturbating? I should try that next~”

“If you do film it, will you show me?”

“Of course! I’ll make sure it gets added to your main rotation of fap material♡”

Oh, nice.

Thanks to Midorigawa, it looks like I’ll be getting some high-quality new material.

“In exchange, you have to show me your own masturbation videos too!”

“You’re already monitoring me with 16 cameras, aren’t you?”

*

“Well then, Kaede-chan’s outdoor masturbation show is about to begin~♡”

With that, Midorigawa used the tips of both hands to start roughly playing with her own nipples.

“Nn… Ah… Nnah… This feels ticklish and good♡”

Her nipples had swollen even more than before, becoming stiff, perky, and incredibly tempting to touch.

Nice~♡ I wanna play with Midorigawa’s stiff nipples too~♡

As I stared with my mouth half-open and nose flaring, Madoka shot me a blatantly displeased glare.

“Onii-chan, what’s with that thirsty look? Do you think it’s okay to stare at other girls like that?”

Actually, in normal society, that kind of stare is the type you’re not supposed to direct at your little sister.

*

“Kaede-chan is getting really turned on now~ So next, I’m gonna suck on these hard nipples~♡”

Suck on them?

Wait… what does that mean?

Midorigawa used both hands to lift her left breast upward, bringing the large areola and its protruding nipple to her own mouth.

Then she stuck out her tongue and began licking her own erect nipple with wet, lewd strokes.

I see. Because her breasts are so big, she can actually do “self-nipple licking”!

She poked it with the tip of her tongue, flicked it left and right, swirled around the stiff nub, and used every tongue technique imaginable to stimulate herself.

Her expression gradually grew more and more melted.

Getting more into it, she took the erect nipple into her mouth and started sucking on it with wild abandon.

Slurp, slurp, slurp, slurp.

She was sucking hard on the tip of her H-cup breast with vulgar, wet sounds.

Her cheeks were deeply hollowed, making her usually dignified face look ridiculously stupid and comical.

To think I would get to witness Midorigawa Kaede like this with my own eyes…

This dream-like scene unfolding right in front of me…

I swear to burn it into my memory and make it my lifelong fap companion — in sickness and in health, until death do us part…

*

Wait, that’s right! The smartphone! I should be recording this!

Even though watching it live is the priority, of course I should also record it on my phone!

What an idiot I am! I almost missed this golden opportunity!

The situation was so unexpected that I hadn’t even thought of something so simple.

Calm down. It’s not too late yet.

I can still recover from here.

Trying not to let Madoka notice, I slowly took out my phone from my pocket while suppressing my excitement.

Damn it, my hands are shaking from tension and arousal.

Even the few seconds it takes to unlock my phone feel unbearably long.

My heart was pounding so violently it felt like it might explode. For a moment my vision blurred, but I managed to hold on and focus.

With trembling fingers, I tapped the camera app icon on the home screen harder than usual.

Come on, activate! My smartphone’s camera app!

With your boasted 48-megapixel low-light performance, capture that “H-cup massive-areola self-nipple-sucking exhibitionist girl” in all her glory!

『The device is overheating. Camera function is temporarily unavailable. Please wait a while before trying again.』

……

You piece of shit phone!!!

Damn it! At this perfect filming opportunity, what the hell are you doing!?

*

Fine. At this point, I can’t afford to be picky!

I’ll have to steal Madoka’s phone and record with that!

I can secretly transfer the data later.

To find an opening to borrow Madoka’s phone, I glanced at her beside me.

……Wait, what the hell is she doing!?

Madoka had slightly stuck her right hand — holding her smartphone — out from behind the edge of the old water tank we were hiding behind.

“You idiot! What if Midorigawa sees you!?”

“It’s fine. We’re completely backlit from her angle.”

Just as Madoka said, since we had the neighboring “Nishiyoko Love Hotel” lights behind us, we were hidden in shadow. It seemed unlikely Midorigawa would notice us.

“Besides, she’s too busy sucking on her own tits to pay attention to a dark corner like this.”

Indeed, Midorigawa’s self-nipple sucking had grown even more intense.

She switched between her left and right breasts, sucking on them greedily and violently.

Slurp, slurrrp, bubo, slurp.

Jupo, bubupo, jupu, slurp.

What incredibly vulgar sucking sounds…

If I ever got the chance to suck on Midorigawa’s nipples, could I possibly suck on them as intensely and obsessively as she was doing right now?

*

“Midorigawa-san must really love having her nipples played with. Even I, who knows my own nipple sensitivity is quite high, can’t get that into self-nipple licking.”

“Can you even do self-nipple licking with your size?”

“Of course I can. I’ve done it before.”

“With breasts that size, you can really reach?”

“I told you I can! Don’t underestimate F-cups!”

“Hmm… I find that hard to believe~”

“Fine then. Next time I’ll show you my self-nipple licking live!”

Heh. My little sister really is easy.

After securing a promise for a future self-nipple licking appreciation session, I returned to the main topic.

“So, why are you holding up your phone?”

“Obviously, I’m recording it!”

This girl is committing yet another crime without the slightest hint of guilt…

“You’re even willing to commit crimes to record this for your Onii-chan. What a filial little sister.”

“Eh? No, it’s not for you.”

“Hm? You’re not going to offer it to me as fap material?”

“Why would I do something that encourages your cheating?”

“Then why are you recording Midorigawa?”

“This is material for later. In case we need to blackmail her someday. Or rather… ‘negotiation material.’”

……My little sister may be easy, but she’s also quite cunning.

*

“Recording with a phone is fine, but aren’t you going to use your actual superpower for its intended purpose?”

“Oh right! I got so caught up in making blackmail material that I almost forgot the real goal!”

As usual, she casually revealed another glimpse of her dangerous way of thinking. She put her phone back into the pocket of her long skirt, then muttered quietly while watching Midorigawa — who was making a ridiculous “hyorotto” face and frantically sucking on her own nipples.

“Sexual Fetish Exposure: Melt Down.”

The color of her slightly brownish-black eyes changed to a vivid yellow, like ginkgo leaves in autumn.

“Oh~ That actually looks kinda like a superpower.”

“Compared to what she’s doing, my superpower feels pretty underwhelming, doesn’t it?”

“Honestly, Midorigawa’s lewd behavior is way more abnormal than your ability.”

“Yeah… her actions are far stranger than my superpower.”

“Seriously, a girl this perverted being part of the Disciplinary Committee is clearly an anomaly.”

“No, a perverted Disciplinary Committee member is basically tradition in this genre.”
