StepSister Who Stalks

I am currently standing in front of Nii-san’s high school gate.

Wearing a cap pulled down low, stylish glasses, and a mask.

I’m in perfect disguise, waiting to ambush Nii-san as he arrives.

“(I will protect Nii-san’s v*ginity…!)” 

It’s too suspicious that he, who shouldn’t have work today, suddenly has to come home late.

Sometimes when Nii-san comes home, he has a scent of another woman on him, so I have to keep a close eye on him to keep him safe.

“(Ni-nii-san is mine only…..if he gets touched by another girl…..even the thought of it is unbearable.”)

Even though I hate it, I keep imagining things because I’m worried. 

Like, what if Nii-san is alone with a girl at school right now…

“Actually, I’m quite pent-up right now. From getting seduced by my little sister”

“Hee, looks like it. Ah, you’re right, f-ck~♡”

“Ahahah, I’m really in a pinch you know. But, I don’t have to worry, ‘cause I have you☆”

“Mou~ Kouta’s an idioooot~♡”  

(Tl/n: calm down imouto-chan, don’t imagine your own ntr)

“(Ughhhhhhh!! This is the worst possible scenarioooooo!!)” 

I held my head in my hands and collapsed to the ground. 

Another unpleasant what-if crossed my mind.

“Could it be that Nii-san doesn’t seem tempted by me because he has another girl to satisfy his desires…?”

Come to think of it, I don’t know much about Nii-san social circle. I mean, I don’t go to the same high school as him, so there’s no way for me to know, and it’s only been half a year since I became part of his family.

I love him very much, but in terms of time, our relationship is still quite new, and it wouldn’t be surprising if he had another close female friend besides me. 

Plus, he’s close with someone like Imari-san, who has big b–bs… What should I do!?

“No! What if he’s with her right now….)

Once again, my brain started to imagine it.

“You know Imari, your bre–ts are the best after all.”

“G-gosh. Miyoshi-kun, you’re such a perv, aren’t you?”

“You’re the one who’s a pervert you know? Having such er-tic bre–ts.”  

“Kyaa! You’re such a tease, Miyoshi-kun. Isn’t it your fault that I became like this? You rub them every day…..”

“It can’t be helped, you know? ‘Cause they feel sooo good☆”

“Miyoshi-kun’s a dummy♡”

“(I don’t stand a chanceeeeeee!)”

As I’ve said many times, it’s not that I don’t have confidence in my bre–ts, but they are nothing compared to Imari-san’s.

It’s probably because Nii-san likes big bre–ts that he gives in so easily to Imari-san-s temptations.

“Hic…ic….Nii-san”

Driven by the desire to see him now, I suddenly heard a familiar voice.

“I think the scope of this one is pretty wide, isn’t it?”

“Yeah, and the level seems high too, so we might need a lot of practice.”

“Seriously? This is gonna be tough.”

“It’s payback time for slacking off.”

The two of them, a boy and a girl, were chatting amicably.

“(T-That’s Nii-san!!)”

Just seeing him  filled my heart with happiness.

― But, however. When I saw the person next to him, my shoulders slumped.

“(T-That’s Imari-san! W-Why is she next to Nii-san?)”

Seeing Nii-san happily chatting away with someone else made my heart squeeze tightly.

“(That’s supposed to be my spot! Being next to Nii-san is my VIP seat!)”

I screamed internally.

I think my instincts are pretty sharp.

But now’s not the time to be impressed. I can’t just leave those two alone like this.

“(Alright, let the tailing begin!)”

I followed them discreetly, making sure not to be noticed.

Hiding behind telephone poles and garbage cans while following them.

Meanwhile, the two of them continued to enjoy their conversation, and I occasionally bit into my handkerchief, suppressing my jealousy.

A few minutes later, Nii-san stopped in front of a house and followed Imari-san inside.

Witnessing that moment, I couldn’t help but collapse to my knees.

“The-they’re definitely going to have s*x….”

No doubt. 

Imari-san must love Nii-san and now they’re going to have s-x!

“(This is bad!!!)”

In a moment of panic, I instinctively pulled out my phone to call Nii-san – just then.

“Um, excuse me, but…”

“Huh?”

A police badge was presented to me.

A smiling police officer.

“(Nii-saaaaaaaaaaaaaaaaaaaan!!!!!!!!)”
