Among other things, there was Lucky Pervert and some other unfamiliar words.
The only thing I could barely guess was that, thanks to the Mythic authority called Divine Physique, I was good-looking. The rest? No clue.
First, I needed to wash up.
The first step to not becoming the big brother hated by his pretty little sisters.
'There's an insane amount of toiletries here.'
As an only child, this was my first time living in a house with so many women, so honestly, I was flustered.
I casually picked up a shampoo bottle.
ZAP!!
"Ugh!"
What the hell? That felt more dangerous than just static electricity… My whole body was tingling.
Looking in the mirror, my eyes turned crimson as I began to understand what had just happened.

"...."
So she put up a barrier to keep me from touching her stuff?
I tried picking up something next to it, and this time, an even stronger electrical-type magic shot through my body.
CRACKLE-ZAP!
"Ghk!"
That… hurt like hell.
Maybe I should just give up on washing and leave…
"Big Bro? Is something wrong?"
Then, Serena's soft voice called from outside.
If it's Serena, maybe I can trust her.
"Do you know where my toiletries are?"
"Didn't you say you don't use that kind of stuff…?"
...?
In a house with two little sisters, did the previous me just wash with water…?
"...I decided to start washing properly today."
A brief silence.
From the other side of the door, Serena spoke.
"You can use mine. The ones on the right are safe."
The fact that Serena called them "safe" suggested that Big Bro (the previous protagonist) and Stella had fought over this issue more than once or twice.
Was not washing his way of asserting dominance?
Fucking disgusting…
Remembering the stained white T-shirt, I scrubbed myself harder than usual, putting extra force into my fingertips.

[Grope little sister Serena's breasts]
...What the hell is this now?
The mysterious ability, Lucky Pervert, activated out of nowhere.
Grope my little sister's breasts? Are you insane?
I don't see Serena as a blood-related sister, so if we weren't connected by blood, I could see her as a romantic interest.
But that's beside the point, suddenly groping her chest? That's bullshit.
I decided to ignore it.
After drying off and stepping out into the changing area, I realized...
Serena was still there, waiting for me.
"Serena? Why are you still..."
"Huh? Oh, I thought you might have laundry…"
She was holding the T-shirt I'd carelessly tossed aside.
"I'll take care of it."
Don't dirty those pretty hands with this.
Before I could even finish the cringy thought, my body moved on its own.
And then...
"Eek…!"
My foot slipped.
"Whoa...!!"
At that moment, as I slowly toppled over my soft, black-haired, purple-eyed little sister...
I remembered what Lucky Pervert was.
It was that cliché, cringe-inducing rom-com trope. Falling into an awkward position with a girl, getting tangled up, and having an embarrassing yet thrilling experience.
In reality? It was definitely a sex crime.
A girl blushing from a sudden touch and developing feelings? That shit jjust doesn't happen in real life…
'No!'
I tensed every muscle in my body to avoid doing something stupid...
'Wait…'
If she falls backward, she could get seriously hurt!
To protect her, I wrapped one arm around the back of Serena's head and...
With my other hand, I ended up grabbing a full handful of Serena's ample breasts.
Squish...!!
"...."
"...."
Two squeezes… and this was undeniably sexual assault!
I immediately pulled my hand back and stood up.
"Sorry."
"…Mmm. The floor's slippery… gotta be careful, Big Bro…"
What kind of ancient, overused trope is this? Goddess of Eroge, I swear…
Overwhelmed by more guilt than I expected, my head spun.
Sure, the explosive softness of those all-natural breasts was beyond imagination, and for a moment, I was happy.
But at this stage...
I couldn't just recklessly push my desires onto her, the girl who was supposed to become my new family. My rationality screamed inside me.
'Maybe we could develop that kind of relationship later. But not now.'
I helped Serena up.
"You okay? Hurt anywhere?"
"…Big Bro… you've changed."
"...."
...Well technically, I am a different person.
Even after what happened, Serena didn't seem to hate me.
Her sparkling violet eyes held a poorly concealed curiosity.
[[Lucky Pervert] Activated]
[Slip and grab little sister Serena's breasts with both hands]
?? The fuck, does this thing have no internal cooldown time?!
"Hold on."
This situation was dangerous in so many ways.
My brain and dick were simple, just recalling the sensation of Serena's breasts had me half-hard, already threatening to tear through my underwear.
This was a problem. If Lucky Pervert activated again like this, I'd be an undeniable sex offender.
If Big Bro started groping her tits like an animal, even Serena's kindness would reach its limit, and I'd be starting my new life in prison.
That can't happen!
Is there no ON/OFF function?! I turned away and fiddled with Lucky Pervert.
"Big Bro? Why are you checking your status?"
"Uh… well."
Got it. The Lucky Pervert font turned red.
That means… deactivated, right?

...Huh?
This time, my brain truly short-circuited.
