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

Chapter 17: You Are the Merciless Naked Queen (Part 3)

Our goal for today was to directly witness Midorigawa in the act and trigger Madoka’s superpower — “Sexual Fetish Exposure: Melt Down.”

Now that the goal had been achieved, all that remained was to return without being noticed by her. However, given our current positions, it was impossible to reach the external staircase without her seeing us.

In other words, we needed Midorigawa to leave the rooftop before we did.

But she clearly had no intention of leaving until she was fully satisfied with her exhibition play.

Which meant we had no choice but to stay and watch her sexual performance until she “finished.”

“Well, well… It looks like we’ll have to keep observing Midorigawa a little longer, even if it’s against my will.”

“Onii-chan, that’s the most excited face I’ve ever seen you make.”

Almost as soon as our conversation ended, Midorigawa pulled her mouth away from her nipple with a wet pop, seemingly finished with her self-nipple sucking session.

What? It ended so soon after I got my hopes up?

My dick was also “excited,” but now it feels like an incomplete combustion…

“Aah, that felt so good♡ But Kaede-chan’s masturbation show isn’t over yet♡ After getting my nipples nice and sensitive~ it’s time for the main dish of tonight’s show~♡ Yay♡ Let’s raise the vibes and cum hard~♡”

She declared loudly to her smartphone camera that she would continue masturbating.

So it wasn’t over after just playing with her nipples.

If she’s calling it the “main dish,” then obviously…

“Next, Kaede-chan is going to use her smooth, bald pussy to have a serious orgasm masturbation session~♡ Yay♡”

Yeah… I figured.

“Doing genuine masturbation in a place like this… Midorigawa-san really is a dangerous woman…”

“You don’t get to be shocked when you’re the one who started masturbating in the back seat of a taxi.”

Madoka pulled out her smartphone again from her long skirt pocket, turned on the camera, and pointed it toward Midorigawa.

“Alright, Midorigawa-san, I’ll be sure to capture every bit of your embarrassing performance!”

With completely clear eyes and zero guilt about the voyeurism, Madoka stared at Midorigawa.

As expected of the girl who installed 16 surveillance cameras in her brother’s room — her resolve is on another level.

It’s a shame I can’t record with my own phone, but since we have this rare opportunity, I might as well enjoy Midorigawa’s genuine orgasm masturbation show live♡

Midorigawa put her index and middle fingers into her mouth and coated them with saliva.

“Well then, Kaede-chan is going to use her soaking wet, horny bald pussy to start a serious masturbation session~♡ Yay♡”

She spread her legs wide in a vulgar M-shape and slowly inserted her two fingers into the slit of her smooth pussy.

Even from this distance, the insertion looked so wet and sticky that I could almost hear the nupu nupu sounds.

“Ahah♡ My fingers went inside♡ Nnah♡”

While letting out hot breaths and smiling, Midorigawa pushed her fingers deep into her own pussy.

Her honey pot swallowed the two fingers all the way to the base. Because she was completely shaved, the entrance of the hole that was accepting her fingers was clearly visible even from here.

“Ahah♡ They’re all the way in♡”

While keeping her fingers buried inside, she made a peace sign with her left hand next to her face.

Then, still holding that pose, she began violently fingering herself with her right hand.

Slurp, zuchu, gunupo, slurp.

Every time she pulled her fingers out, the entrance of her pussy narrowed as if trying to suck them back in, with sticky membranes clinging to her digits.

“Ah♡ Ah♡ Ah♡ It feels so good♡ My pussy feels so good♡ Kaede-chan is feeling it from her bald pussy masturbation♡ Nn♡”

Gulp…

Watching her wild pussy move so obscenely, I couldn’t help but swallow hard.

I wonder what it would feel like to put my fingers inside that hole…

The softness of the flesh, the sucking of the membranes, the melting body heat.

It was easy to imagine that all of it would far exceed anything a virgin like me could dream of.

Seeing the raw, living movements of a female body — something you can never experience through AV on a screen — made my heart throb with desire.

I honestly thought: I want to put it in.

I want to insert my cock into that pussy.

For the first time in a long while, I clearly felt that primal male instinct.

Faced with the ultimate “female” known as Midorigawa Kaede, the small “male” inside me quietly awakened.

Since I was born a man, I want to taste the finest woman…

That fleeting desire I had long given up on after 17 years of life surged up uncontrollably.

That’s how overwhelmingly “in her prime” the girl masturbating furiously before us was.

Slurp, zuchu, gunupo, slurp.

“Ah♡ Nn♡ Good♡ Nn♡”

Her cute moans — even cuter than Madoka’s — leaked out in time with the movement of her fingers.

“Well then, I think it’s time for the finale♡”

With those words, in addition to the intense thrusting of her two fingers, she began using her elegant, slender thumb as well.

She poked and rubbed the front of her pussy vigorously.

She was probably stimulating her clitoris.

The moment she added that extra pleasure, her expression of ecstasy became even more intense.

“Aaah~♡ This is bad♡ This is so bad♡ Ah♡ Nn♡ Nnah♡ Nn♡ Nn♡”

Her melted eyes, loosened eye corners, stupidly stretched nose, vulgarly open mouth, and drooling tongue — it was quite possibly the most beautiful ahegao in the world.

Slurp, zuchu, gunupo, slurp.

“Aaah~♡ Ah♡ Ah♡ Ah♡ Ah♡”

The sounds coming from her mouth no longer had any meaning.

Judging by how thoroughly pleasure had ravaged her thoughts, her climax was clearly approaching.

“Aah♡ Aaaah♡ I’m cumming♡ I’m cumming♡ I’m cumming cumming cumming♡ I’m cumming while fingering my pussy outdoors♡ I’m cumming from bald pussy masturbation while fully exposed♡”

Twitch! Twitch twitch twitch! Twitch! Twitch twitch! Twitch!

Midorigawa’s vulgarly spread knees were trembling like they were laughing.

Her hips thrust forward several times, her back arched sharply, and she froze with her face turned toward the starry sky.

“Haa— Haa—”

She continued breathing heavily toward the heavens, remaining in a dazed state for a while.

……I just witnessed something incredible.

When something is this extreme, you feel more moved than aroused.

“Hey Madoka, it looked like Midorigawa reached a spectacular climax, but did that still not reach 10,000 Spell?”

“Yeah. She only hit around 9700, so that wasn’t enough.”

“So just cumming normally isn’t enough, huh.”

“It’s important to release their inner sexual desire. That’s why we need to figure out their ‘climax conditions’ — to fulfill their ‘wishes.’”

“So, did you see it? With your Sexual Fetish Exposure: Melt Down, did you figure out Midorigawa’s ‘climax conditions’?”

In response to my question, Madoka didn’t speak. Instead, she raised her index finger to her lips in a “shh” gesture.

I wondered why — then looked toward Midorigawa and saw that she had finally snapped out of her post-orgasm daze.

She ran her fingers through her long, glossy hair with her right hand in a smooth motion. Her expression had returned to the dignified, elegant Midorigawa Kaede we knew from school.

Having returned to the appearance of a model student of Eguchi Sugi Academy, she picked up her smartphone and walked casually toward the spot where her clothes were neatly folded.

It seemed that tonight’s “Kaede-chan Masturbation Show” had finally come to an end.

She put on the lime-green bra and panties I had enjoyed earlier, then smoothly dressed in her shirt, skirt, ribbon tie, blazer, navy socks, and loafers.

Once she had returned to the image of a proper student, she walked toward the external staircase with an innocent face, as if nothing had happened, and began her descent.

For a while, the sound of her footsteps on the stairs echoed, gradually growing fainter until they disappeared completely.

……

The rooftop of the abandoned building regained its original silence.

Phew~ Well, today’s mission is safely complete.

“Did you see it, little sister?”

“Yeah, I saw it perfectly!”

“As expected, her huge areolas were slightly sticking out from her bra!”

“No! I’m talking about her ‘climax conditions’ that I saw with Sexual Fetish Exposure: Melt Down!”

“Is that topic really more important than her vulgarly huge areolas?”

“Yes, it is!”

“By the way, about the size of those massive areolas~”

“Wait, wait, how much do you want to talk about that!? …Fine, I’ll keep you company until you’re satisfied.”
