Damn it!
I nearly slammed my fist into the wall.
My elegant masturbation time, now completely ruined.
This wasn't the first time my younger sister had brought friends home. It had happened countless times before.
Each time, her room next door would inevitably become a noisy, bustling hubbub.
In the past, I hadn't yet developed this particular habit, so I never flew into a rage like this. Still, it always annoyed me.
If only she would bring home cute girls, I'd gladly welcome them with a smile.
I'd strain my ears against the wall next door, or feign ignorance when entering the freshly used bathroom.
But it's as if she's deliberately targeting them—every single one of her friends is a plain Jane. At best, just average.
Even from my older brother's perspective, Matsuri is undeniably the cutest.
But these girls... they're completely unappealing. My manhood doesn't even twitch around them.
This is truly the worst.
Some guy I don't know, let's call him Friend A. What am I supposed to do with this week's worth of built-up semen?
Am I supposed to curl up in my room and endure it with just hand-to-penis friction?
My nerves are incredibly delicate. If I hear stupid laughter from the next room, I'll lose my focus and go limp.
I'll inevitably start suspecting they're badmouthing me. And to be fair, they usually are.
So, in short, my younger sister's friends are my enemies too.
An enemy's friend is also an enemy. It's just common sense.
I can't take this anymore. I can't go on.
I'm so furious now that I've decided to leave my room and go out.
I'm feeling quite bold right now.
Normally, I'd be quietly holding my breath in my room until my younger sisters calmed down, but maybe this is the energy boost from my abstinence.
If I leave now, I'll run right into them, and Matsuri will probably give me a nasty look, but I don't care.
Bring on the harassment. The trouble I'm already enduring is on a terrorist level, far beyond mere harassment.
And while I'm at it, I won't feel satisfied unless I mentally curse the face of my younger sister's friend, thinking, "Ugly bitch!"
Without hesitation, I flung the door open with a clack and stomped down the stairs, my footsteps echoing loudly.
When I reached the entrance, I saw her. I glared at her with the same intensity a parent would reserve for their mortal enemy.
An unfamiliar back view. Straight black hair, slightly longer than her shoulders.
A fluttering dress patterned with white and pink flowers.
From it emerged slender, pale arms and bare legs.
She was bending over, sticking out her rear, arranging the shoes she had removed.
The moment I saw her, I gasped involuntarily, my breath catching in my throat.
Isn't this... Ali? No, isn't this definitely Ali?
Though delicate, her rear has just the right amount of softness.
If I were to lift the hem of that dress, slip my cock between her panties, and rub against her... she'd probably feel amazing.
Her legs are also a high point. Flawlessly white, glowing like porcelain.
If she were to step on me with those bare legs, stroking me gently up and down, sometimes roughly... I'd be on the verge of ecstasy.
Well, this is just my imagination running wild based on what I've seen in porn, but it definitely sounds amazing.
The more I observe him, the fewer flaws I can find. Is he really Matsuri's friend?
I'd give him at least 90—no, 95 points.
I always use Matsuri, who's closest to me, as my standard, so my evaluations of girls tend to be quite strict.
Getting over 90 points from me is no small feat.
But that's only if I'm judging him solely on his back view.
He'll definitely pull a huge prank in the end. That's what makes him Matsuri's friend.
After finishing to straighten her shoes, she turns around.
Noticing me staring intently at her rear, she slowly bows her head.
"Hello, I'm intruding."
She smiles at me.
I freeze, unable to react.
A massive shock, like being struck by lightning, courses through my entire body.
It's been years since I last remember a woman smiling at me.
At best, it might happen occasionally when I go to church.
One glance was enough to tell. Her bow and greeting alone made it clear she must be a well-bred young lady.
Otherwise, no woman would ever smile at a self-proclaimed average guy like me.
She couldn't possibly suspect the erotic fantasies swirling through my mind.
But that wasn't the only thing that stunned me.
No, the real shock came from her face.
Long eyelashes framed by a straight-cut bang, large black eyes, and a wide-set double eyelid.
A clear, straight nose bridge, and small, well-shaped lips that weren't too thin or too full.
This was an undeniably beautiful girl.
She surpassed the standard. This was an inevitable triumph over Matsuri.
Well, even with the slight negative bias I have toward my younger sister, I still think she's better.
Oh man, this is bad.
What's bad is that just a simple greeting is making me get a little hard.
But I can't worry about that right now. I need to respond.
"Uh, yeah, uh..."
Flustered, I managed a confused groan.
Still, she didn't make a disgusted face, like "Ew, gross," but kept smiling.
Our eyes met, and as I fidgeted awkwardly, a loud, exaggerated click of the tongue came from right beside me.
Startled, I hastily glanced over.
There was Matsuri, my younger sister, glaring at me as if she'd seen something utterly revolting.
