"Haa~"
Alone in my room, I rested my cheek on my desk and sighed.
It had been almost three days since that dreamlike time ended.
"Miki-chan..."
I muttered to myself, completely drained, both physically and mentally.
I still couldn't believe I'd met a girl so cute and erotic, exactly my type.
The recent events felt so surreal, I kept wondering if it was all just a dream.
But upon reflection, I realized I hardly knew anything about Miki beyond the fact that she was Matsuri's friend and attended the same school.
Of course, she probably had a boyfriend. I wondered what kind of guy she was seeing.
Anyone who could date a girl like that was seriously the luckiest bastard alive.
And when I imagined the two of them doing that and this together, I couldn't help but pound my fist against the wall.
At the same time, my mind began to wander with improper fantasies, and my penis started to swell.
After that, Miki fled back home.
If that damn father hadn't lost so badly at pachinko, things might have gone further...
Because of the awkwardness at the end, nothing was said this time.
No "No masturbation for a week," and no "I'll come again next Saturday."
In other words, there's a real chance I'll never see her again.
My only hope is... she did say she liked my penis.
Does that mean there's still a chance, as long as it's just my penis?
Come to think of it, maybe my whole body should just be a penis.
In that case, calling it "penis" is probably not respectful. I should start referring to it as "Mr. Penis."
Still, after everything we've been through, I'd like to believe she's at least a little curious about the "accessory."
Well, I probably said that half-jokingly.
And if Miki were the kind of slut who would immediately start performing lewd acts upon seeing a penis...
Now I'm so preoccupied with wanting to know more about Miki-chan that I can't even get into masturbating. It's not like it's forbidden or anything, but I haven't jerked off even once since then.
I'm dying to learn more about Miki-chan... but it really stinks that she wouldn't even give me her contact info.
I could ask Matsuri, but I doubt she'd tell me the truth.
Hmm, Matsuri...
Matsuri herself is a little... off.
Our relationship remains as distant as ever, but lately, there's been an odd distance between us, something different from before.
The distance between us feels forced, almost deliberate.
Out of nowhere, she'll catch me looking her way and our eyes will meet, only for her to deliberately avert her gaze with a hmph.
Even today, when I was back home fiddling with my phone in the living room, Matsuri came home later looking disgruntled but inexplicably lingered in the room.
Normally, she'd head straight back to her room as soon as she saw me.
Yet she didn't say anything either... It's all just so annoying.
Well, I don't really understand what she's thinking anyway, so it probably doesn't matter.
More importantly, there's Miki-chan.
Before I know it, it's almost ten o'clock at night.
As I foolishly let my imagination run wild, writhing in my seat, there's a perfunctory knock at the door, followed immediately by the lock clicking open.
Huh? I turned around and saw Matsuri standing in the doorway, still in her nightgown, wearing an indescribable expression.
"What... what do you want?" I asked, unable to stand the silence when she just stood there motionless.
She hesitantly held out a notebook and what looked like textbooks.
"H-homework..."
Homework...?
Ugh, this again.
But she'd been quiet for the past few days—yesterday, the day before, and so on. Why bring it up today of all days?
Well, the most natural explanation would be that she had a particularly annoying assignment due today.
Tch, like I have time for this... I mentally clicked my tongue, but then quickly reconsidered.
Doing Matsuri's homework for her was an order. An order Miki-chan gave me—to listen to whatever Matsuri said.
Is that order... still in effect?
Which means my connection to Miki-chan is still...
"Ugh, more homework? Ugh... well... it's Miki-chan's order, you know."
I deliberately emphasized the "Miki" part.
Really, I wanted to ask her anything about Miki right away, but I didn't want to make her suspicious.
If I was going to do this, I had to be subtle.
I stood up, snatched the notebooks from Matsuri, who was standing there dazed, and took them back to the desk, where I started working with feigned enthusiasm.
After all, every time I completed one of these orders, it was another opportunity to interact with Miki.
After showing me the problematic section, Matsuri sat back down on her cushion and started fiddling with her phone without another word.
Occasionally, looking restless, she would stand up and crane her neck over my shoulder as I worked at the desk.
Ignoring Matsuri, I focused intensely and finished my homework at lightning speed.
When I put down my pen and looked up, Matsuri had somehow fallen asleep on my futon.
"Hey, don't just barge in like that..."
My futon hadn't been washed since the last time I'd messed it up—it was honestly filthy.
I couldn't exactly say, "I need to wash the futon because I sprayed it with semen," so I'd just wiped it down and sprayed it with deodorant.
When I pointed this out, Matsuri sat up hastily, her gaze darting around as she replied.
"Huh? Oh... Y-you're already done? T-then next... Y-you want a shoulder massage...?"
A shoulder massage now? Is she following the same routine as before?
Well, whatever. For now, I'll humor her and pry every detail about Miki out of her.
I agreed quickly, "Sure, sure," climbed onto the bed, moved behind Matsuri, and rested my hands on her shoulders.
Matsuri tilted her head slightly, glancing at me sideways as she asked, "Hey, you're being awfully... sincere today."
"Well, well, it's just following orders. Miki-chan's..."
She emphasized "Miki" again.
The moment she said that, Matsuri's gaze sharpened noticeably.
"What? What is it?"
"...What? What's wrong?"
Matsuri brushed my hand off her shoulder, turning to face me and sitting up straighter.
It seemed I'd been caught. She was visibly irritated now, radiating an aura of displeasure.
"Why would someone like her...?"
"...Huh? What?"
"Nothing!"
Despite insisting it was nothing, her mood had clearly soured.
This wasn't the time for any more unnecessary remarks.
Matsuri gritted her teeth in frustration before speaking again.
"...Just so you know, Miki is incredibly popular. She can choose any guy she wants, and someone like you... you're not even on her radar."
...Right?
I knew it, but hearing it said outright still comes as a shock.
"Hey, I know that. Miki-chan is cute, after all..."
"Cute, sure... But Miki is seriously... different. How do I put it? She's just... kinda messed up."
Wait, now he's starting to trash-talk her.
Well, I get what he's trying to say.
Like how she'll catch her friend's brother jerking off and then suddenly start groping his penis.
And then it doesn't stop there... Honestly, that's not normal.
So this kind of thing really is just a regular occurrence for her?
"Y-you think Miki-chan is always like that?"
"...What do you mean, 'like that'?"
"Well, you know, getting all... erotic with guys..."
"B-baka! There's no way!"
Huh? So she doesn't just freely hook up with random guys?
I'd always assumed she was secretly known at school as a slut or a bitch.
"S-so what's so bad about her?"
"Well... apparently she's been dating older men since middle school... and, you know, doing all sorts of things with them..."
It seemed there was a bit of a misunderstanding between Matsuri's definition of "bad" and mine.
Maybe I'd been reading too many weird AVs or porn books.
That's all? I thought. But then I remembered... Wait a minute, she did this and that with Miki-chan, the junior high girl...?
Who the hell is that guy? He deserves to die ten thousand deaths!
I hope he gets caught for violating some law or ordinance. Actually, I hope he gets beaten to a pulp.
"Huh... so what about now?"
"N-now? I don't know!"
With that, Matsuri turned her face away in a huff.
Why did she get a little snappy about that? I just wanted to ask if she still had a boyfriend and stuff...
Besides, she always criticizes Miki for dating boys since middle school, but you did the same thing, didn't you?
What are you acting so sanctimonious for?
"It's fine, just massage my shoulders!"
Matsuri turned her back to me again.
Sigh, at this rate, she'll never give me Miki-chan's contact info.
Honestly, what a useless younger sister. Should I just half-ass this and send her on her way?
I placed my hands on her shoulders again and resumed massaging from behind. Her shoulders were soft and pliant, showing no signs of tension.
Well, there's no point in massaging these, I thought, when Matsuri's body suddenly wriggled in a suspicious way.
She seemed restless, fidgeting uneasily.
"...What is it?"
"S-something about being touched from behind..."
"...Being taken from behind?"
Matsuri didn't say it outright, but that single phrase made everything click immediately.
Haah, this little... She's remembering what happened last time, isn't she?
Back then, I had her pinned from behind, relentlessly teasing her, and that sensation must be resurfacing subconsciously now.
Recalling Matsuri's previous disgraceful state, I can't help but smirk a little.
Despite acting so superior, she came from my touch, didn't she?
This indescribable sense of superiority is overwhelming. Though I should probably ignore the fact that she made me cum more times than that.
But Matsuri was undeniably adorable back then, and so damn sexy...
As I sift through the memories, an inexplicable arousal suddenly stirs within me.
And it's not just because she's freshly bathed—Matsuri's scent alone rivals or surpasses Miki-chan's.
She really smells amazing...
"Hyaa!"
At that moment, Matsuri's body gave a little start.
...Huh? What was that?
"Y-you just blew on the back of my neck, didn't you?!"
"N-no, I didn't!"
"You did!"
Oh no, did my breathing get rough because of the scent?
Still, even if she did feel my breath on the back of her neck, it was just a tiny little puff.
Isn't she being a bit too sensitive?
"Ugh, stop it!"
Wait, though... she doesn't really seem angry.
In fact, she looks like she's kind of enjoying it.
What is this girl...?
Well, nothing beats getting her in a good mood.
If I keep this up, I might be able to casually bring up Miki-chan...
With this thought, I figured I had nothing to lose and decided to try blowing a little breath on the back of her ear.
"Kyaa!"
Matsuri flinched again and turned to me, playfully tapping her fingers against her side.
Oh man, I'm starting to grin involuntarily. She's kinda cute, isn't she...?
Getting carried away, I took advantage of the moment to tickle Matsuri's side with my finger.
"Kyaa! Stop it!"
Matsuri swatted my hand away and pressed a hand against her side. Her cheeks puffed out, but her eyes twinkled with amusement.
Seeing this reaction, I figured I could push it further and tickled her other side. She protested, "Hey! Stop it!" but she seemed to be enjoying it.
Hmm, she's got quite the sultry voice.
And her exaggerated reactions were pretty entertaining.
...But I should probably stop here.
The thing is, my crotch was starting to tent slightly.
We'd only been teasing each other a little, but this was getting out of hand.
"Hey, aren't you getting a little... excited there?" she teased, trying to force me to admit it.
Really, I didn't want her to notice my lower body was reacting...
Whether it was because her words sounded unnatural or because I inadvertently showed it on my face, before I knew it, Matsuri's gaze was fixed squarely on my crotch.
Suddenly, she pointed a straight index finger right at it.
"By the way, isn't that..."
"W-What?"
"Isn't it... swollen?"
"Huh? What do you mean?"
"That thing!"
"T-This?! This is just... a little wrinkled, that's all..."
Damn, she'd noticed.
But it wasn't a full erection yet, so I still had a chance to bluff my way out...
Or so I thought.
Matsuri abruptly extended her pointing hand and grabbed the tent pole with a firm grip.
"Ah..."
...She caught me. I never expected her to actually touch me directly.
How did my younger sister become so unhesitating about grabbing her brother's penis?
It's all his fault. His influence has spread even to this...
"Ugh, gross! It's gotten bigger! You pervert! You pervert!"
After groping someone's penis without permission, who are you to complain?
Matsuri cheered as if she'd severed the head of a demon—or rather, the glans of a penis.
"Hey, hey! I'm not doing anything erotic! So why is this happening? Huh? Why, why?"
Grrr...
Last time, I could at least blame it on items like freshly removed underwear, but this time... I have no excuse.
This makes me look like some perverted otaku getting aroused just from messing around with my younger sister.
I need to give Mr. Penis a proper scolding.
Sorry, but you're being a little too relentless. This is starting to get embarrassing. I guess I need to take care of myself properly every day.
Overwhelmed by shame and fluster, I couldn't bring myself to meet Matsuri's smug gaze and averted my eyes.
My face must be beet red by now. She's cornered me completely, leaving me utterly defenseless.
That damn little sister! She's seizing every opportunity to tease me.
But as her older brother, I can't let this low-class brat keep humiliating me.
Squeezing my brain dry, I decided to turn the tables and go on the offensive.
Or, to put it bluntly, I was half-desperate.
"T-That's... because... Matsuri, you're just... c-c-cute!"
I meant to deliver it like some A-list actor (or Kirigaya-sensei) would, but I stumbled over my words.
Even if I was just putting on an act, I still felt a strong resistance to spitting out such a line to her face.
Thanks to that, things ended up feeling a bit too serious...
Matsuri, the main character, just stood there with her mouth agape, completely silent.
Is she appalled...?
Well, at least she's calmed down, so I guess the outcome isn't bad.
"Ugh, it's freezing! What was that just now?" Before she could start cursing me again, I scrambled off the bed as if fleeing.
Suddenly, a firm grip seized my wrist.
Huh? I turned around, startled. Matsuri, still slightly averting her gaze, began mumbling in a low voice.
"Um, about that..."
"Yeah?"
"To tell you the truth... I was feeling a little turned on earlier, too..."
...Huh?
"I-I remembered what happened the other day... And it felt so good..."
...Huh?
"So I was thinking... I wanted you to do it again, like you did before... Because I can't do it myself..."
...Huh?
"If you don't want to, that's fine..."
As she spoke, Matsuri looked up at me with pleading eyes, her gaze shy and indirect.
I stared down at her, frozen in place.
