"What? You're still here..."
In a panic, I reached for my pants and underwear, which I'd hastily kicked to the floor, but it was too late.
Worse still, as I bent down to retrieve my trousers, I slipped on the semen that had splattered across the floor—whether from the slickness or something else, I lost my balance and fell flat on my face.
"Ow!"
My flustered haste had caused me to tumble in a completely disoriented heap.
My butt was throbbing with pain, but the thought of my younger sister seeing me sprawled naked from the waist down was far worse.
I scrambled upright immediately. In my frantic haste to get up, though, I hadn't even considered my orientation.
When I rose, I found myself face-to-face with my younger sister. Right, she probably already knows by now.
In other words—in the end—I had inadvertently exposed my half-erect penis to my younger sister, right in front of her.
It was practically a blatant flaunting.
Matsuri froze when she saw it.
She stood there, wavering between opening the door or not, clearly reluctant to enter my room.
Just as I thought I'd peek inside to see what was going on, she caught a glimpse of my brother standing tall, his erect penis exposed—a highly inappropriate sight.
What must she be thinking right now? To be continued.
I wanted to escape reality with that teasing line, but reality had other plans.
It felt oddly similar to when Mother caught me masturbating.
The sudden rush of arousal, followed by a numbing detachment as I calmed down—the masturbating high.
In that eternal moment, I froze, still exposing my penis, contemplating what lay ahead.
Would this lead to a family meeting—a judgment? From now on, I probably wouldn't even be allowed to speak. No, not even make eye contact.
But in that frozen moment, one person remained free to move—a transcendent being.
It's Miki.
"Matsuri-chan?"
Matsuri stood frozen. I waved my hand at her.
Whether it was in response or not, she finally started moving again.
She had been frozen, staring wide-eyed at my crotch, but with a squeal, she covered her eyes.
What's with that typical girl reaction? I thought she'd spit in my face and snap, "Don't show me something filthy!" instead.
Still covering her eyes, Matsuri's lips trembled as she stammered, her voice shaking:
"W-What... what are you doing?! Wh-what kind of outfit are you wearing in front of Miki, you perverted man?!"
"N-no, it's not like that. It's a long story..."
"W-wait, never mind that! Just put on some clothes and hide that thing—quickly!"
I thought she'd either ignore me or start cursing, but Matsuri was so flustered she couldn't even form words.
Apparently, she really didn't want to see my penis.
She's probably seen penises before, so why the reaction like it's her first time?
Wait a minute... Does that mean if I keep my penis exposed, Matsuri won't curse at me?
If I'm lucky, she might even back down completely.
Well, it's too late for that now, I thought, deciding to observe the situation a little longer.
"H-Hey! Are you even listening?! Hurry up and put that away, I said! M-Miki, stop just standing there and say something! Seriously, what are you doing?!"
My penis barrier was working.
Matsuri, unable to look at me, redirected her anger toward Miki.
"Well, I felt bad for interrupting your masturbation, big brother."
"O-Oh, masturbation... W-Why would you do that?!"
"So, I was just helping out a little."
"H-Helping out... What are you talking about, you idiot?! Why would you...?"
"Huh? But Matsuri-chan told me her ex-boyfriend used to do it all the time for her, right?"
"Wait, that's..."
Wow, do girls really talk about stuff like this all the time?
Matsuri, she's such a total bitch.
And Miki, seriously, why would she just blurt out what happened like that? Can't she just lie a little?
Well, in this situation, there's really no excuse, so if honesty is the only option, so be it. But still, shouldn't there be some way to smooth this over?
"T-That's different! Why would you do something like this with him?"
"Huh? Isn't Matsuri-chan's brother cute? Even Matsuri said so herself, though she complained it was annoying. She said something like, 'It's not like it's hurting anyone here.' And she even mentioned that guys look so cute when they're all smitten..."
Ugh, what a dyed-in-the-wool bitch...
Even though she's my younger sister, I'm seriously grossed out. I shot a glance at Matsuri, who blushed and lowered her eyes.
What's with that reaction? Well, I guess it's embarrassing to have family spill those kinds of secrets.
"Hey, since we're here, I'd love to see how Matsuri-chan used to do it."
"H-huh?! W-why would I do that?!"
"But you were bragging about it so proudly... Wait, was all that just a lie?"
"Ugh, I'm not lying!"
What's this? I can't quite make sense of it. Did Matsuri pull one of her usual bragging lies again?
No, she's a high school student now. She wouldn't tell such outrageous lies like she used to, right?
"Right? It's not like I'd lie. Look, there's something perfect right there."
"P-perfect... I don't even understand what you're talking about! Why of all things... this thing...?"
"Come on, didn't your brother say that when he remembered Matsuri-chan, he got all grown up?"
"H-huh?"
"He wants to stick it inside Matsuri-chan and go squelch, squelch!"
"H-haaaaah? Wh-what are you saying? That's impossible! Ugh, gross! That's so disgusting!"
Matsuri stared as if she'd seen a monster.
Crossing her arms over her chest and shivering, she clearly looked disgusted.
Damn you, Miki! Why did you have to say that out of nowhere? Acting so calmly about something you forced me to say...
I'd been frozen, unable to keep up with this bizarre turn of events, but now I knew I had to deny it or things would get really bad.
"No, I didn't say that! I never said anything like that!"
"Huh? You totally did!"
Miki's glare (intimidating) left me speechless.
She's really scary. I'm already starting to lose the will to resist.
After silencing me, Miki suddenly turned to Matsuri with a sweet smile.
"Since Matsuri-chan is all grown up now, she should be the one to take care of this."
"I-I don't know anything about that! And you're seriously saying that about your own younger sister...?"
"Look at that! This thing is incredible—it's rock-hard even after three times!"
Miki pointed, and Matsuri cautiously glanced at my penis.
I expected her to look at it like it was filth, but surprisingly, she seemed genuinely startled.
Maybe she was shocked by how big it was?
Being stared at like a rare specimen is undeniably embarrassing.
It's been since we were children since Matsuri last saw my penis. I've shown her my erect penis before, but at the time, neither of us really understood what was going on.
"Huh? No way... What is this...? Is this...?"
"Hmm? What's wrong?"
"N-no, nothing..."
Matsuri stopped herself mid-sentence.
Something's off here. There's no way my pathetic little penis could elicit such a reaction.
Who calls it pathetic?
As I casually glanced at Matsuri's expression, she shot me a sharp glare.
"...What? Stop staring at me!"
After staring so intently at my penis, what are you complaining about?
Matsuri blatantly averted her face from me and turned to Miki.
"We did it three times... Miki, did you really go through with it?"
"Absolutely," Miki replied firmly.
With Miki's definitive answer, Matsuri's wandering gaze returned to me, seemingly lost.
Matsuri couldn't hide her astonishment.
After all, the guy she'd always treated as scum and trash was now... with her friend.
She must be feeling a mild sense of betrayal, like her boyfriend had been stolen.
Serves her right.
I answered Matsuri with a smug expression.
This sense of superiority... you could call it the non-virgin's confidence.
Miki and I are already, well, that kind of relationship.
To confirm this, I deliberately shot Miki a meaningful glance.
But she completely ignored me. Miki's gaze was fixed on Matsuri, as if silently saying, How dare you?
"What's with that attitude? It's pissing me off!"
But my attitude seemed to have a devastating effect on Matsuri. My nonchalant demeanor clearly annoyed her.
This girl just can't stand not looking down on me, so she must be seething.
Well, normally someone strutting around with their penis hanging out like this wouldn't even understand concepts like "superior" or "inferior."
Having switched to non-virgin mode, I decided to vent my usual frustration by standing in front of Matsuri and deliberately provoking her.
"So what if it annoys you?"
"W-what? You piece of trash, getting all smug..."
Even for my usually feisty younger sister, her voice sounds surprisingly weak.
She seems preoccupied with my penis, subtly shifting her body away from me.
I can win this. I'm clearly dominating the situation.
After graduating from virginity earlier, I must be radiating a newfound mental ease.
Hey, Matsuri, keep this quiet, okay? I think, wondering if that would silence her. This way, we can avoid a family meeting.
Just as I'm about to deliver the final blow, Miki interrupts from the side.
"Ugh, it's so annoying, isn't it? Just a moment ago, you were making that pathetic face while I was touching it."
Miki isn't on my side at all.
In fact, she's probably my enemy. But under that scornful gaze, I still can't bring myself to defy Lady Miki.
Miki whispered to Matsuri.
"Hey, Matsuri-chan, if we just mess around with that a little, she'll be all over us in no time. Wanna do it?"
"Huh? Uh, well..."
"What's the matter? For you, Matsuri-chan, that's child's play! Didn't you say you used to have your ex-boyfriends eating out of your hand?"
"U-um... Well, yeah, it's that easy, but... we're siblings..."
"Come on! So what if we're siblings? I mean, every brother and sister pair does stuff with their hands, right?" (We don't.)
"R-really? But in my family..."
"Seriously, why not? Huh, wait, don't tell me... Matsuri-chan, was all that just a lie?"
"N-no, it's not like that! It's not a lie! I can do it! It's... it's easy!"
"Yay! Matsuri-chan's going to show us!"
Miki immediately cheered her on.
...Huh? She's actually going to do it? Matsuri's actually going to do it?
I thought I heard a faint, ominous conversation, but surely my sisters couldn't be that...?
As I stood bewildered, Miki gestured for me to sit down and then had Matsuri crouch down in front of my crotch.
Matsuri was staring blankly at my penis, lost in thought. Miki urged her on.
"C'mon, Matsuri-chan, do it quickly, like you always do."
The voice snapped Matsuri back to reality. With a determined look, she reached toward my crotch.
