"Hey, Matsuri, are you serious about this? This is seriously messed up. I feel like I'm being taken advantage of..."
Before I could even get a word in edgewise, Matsuri's small hand suddenly gripped the completely dry tip of my penis.
"Ow!"
The pain made me yelp involuntarily, my body jerking.
But Matsuri paid no heed, abruptly starting to roughly move her hand up and down, scrubbing back and forth.
My freshly exposed glans couldn't withstand this kind of stimulation.
"Ow! It hurts, it hurts, it hurts!"
"Huh? What?"
When I let out a loud scream, Matsuri startled and abruptly released her grip.
"W-what was that for? Don't scare me like that! D-didn't you like that?!"
"N-no, that hurts! That's too rough!"
I don't know if it's just her usual roughness with her boyfriend or what, but that was way too much.
Just how tough of a penis has Matsuri been dealing with all this time?
"If... if that's what hurts... how about this?"
Matsuri reached out, careful not to touch my shaft, and began stroking the scrotum area.
Her fingers fumbled around, eventually finding my balls, which she began to knead.
Squish, squish, squish.
Oh, this isn't half bad...
I see. So she's attacking from the balls first. Advanced players really are on another level.
This alone isn't enough to make me feel good, but it inevitably heightens my anticipation for stimulation to my shaft.
Squish, squish, squish...
And so, Matsuri continued to focus solely on my balls.
I was eagerly awaiting her touch on my shaft, but there was no sign of it.
...How long is she going to keep this up?
No matter how much she kneads my balls, nothing will happen without some stimulation to my shaft.
"U-um..."
"W-what? Are you about to come?"
"No, no, no."
"Then... then what? Are you going to say it hurts again?"
...Something's off here. Does she think I'll come just from getting my balls squeezed?
Could it be that Matsuri... No, that can't be it. She did have a boyfriend, after all.
I even remember once when I brought her home, I pressed my ear against the wall, waiting to see if they'd start doing it in her room.
Her previous partners must have handled their penises differently.
Besides, I don't want to get hurt again. Thinking about it calmly, this is probably a bad idea. Siblings shouldn't be doing this kind of thing...
The whole situation of Matsuri touching my penis is just plain abnormal.
And she seems kind of desperate...
"Let's stop this. It doesn't feel good at all..."
"W-What do you mean it doesn't feel good?! I-I don't understand! Y-You're the one who's weird!"
Why is she angry at me? That's the part I don't understand.
In what world does a man come from just the head? Well, maybe some people can, but I certainly can't.
Then, as if witnessing a heartwarming scene, Miki, who had been watching our exchange from the side, interjected.
"Matsuri-chan, your brother's glans is still raw. Wouldn't it hurt to rub it dry?"
"R-raw...?"
As Matsuri's face filled with confusion, Miki leaned in until her face was just above the glans.
Then, from the corner of her mouth, she dripped a slow stream of saliva. The viscous droplet fell, trailing a thread, and coated the glans.
H-h-how erotic...
Matsuri and I watched, stunned, as Miki casually said:
"Here you go, Matsuri-chan."
She took Matsuri's hand and forced it against my penis.
Matsuri grimaced for a moment, but quickly recovered and began moving her hand.
Her smooth hand glided over the glans, now slick with saliva, reducing friction.
As she moved, the nearly dried-up lotion was revived, creating a slight lather and emitting soft schlick sounds.
"Ah..."
The moderate pressure against the glans elicited an involuntary moan of pleasure.
The jerky, almost awkward movement of her hand—gripping and trembling slightly—was different from before, but the sensation was far superior.
Part of it was because she had been teasing me relentlessly with her fondling of my balls.
But her moan seemed to confuse Matsuri. She stopped abruptly, then resumed with a weaker grip, moving slowly as if still startled. It was all terribly frustrating.
The stimulation is either all at the top, suddenly moving down, or just random.
No, that's not it... This is different...
Matsuri's clumsy movements make me restless.
I can't believe this is anything but deliberate. Is this harassment?
But then again, depending on how you look at it, it's not so bad.
This is what they call tease play. To suddenly pull out such advanced techniques like this...
But what about Miki? I glance sideways at Miki, who's watching intently.
"...Matsuri-chan is desperately working on his cock... huff... huff..."
Miki pants heavily, staring at Matsuri with ravenous intensity.
...Is she more excited than I am?
Feeling like I'd seen something I shouldn't have, I quickly averted my gaze, only to meet Matsuri's eyes.
"W-what do you think? D-doesn't it feel like you're about to come?"
"N-no, I don't know... It's a little..."
"Huh? W-why not? You're just being stubborn again!"
...Could this actually be serious? Was she really trying to make me come with that movement, instead of just teasing me?
How long does she think I last? Well, I guess I can't blame her—I haven't come even once yet.
Even I, the great me, can't go that easily on the fourth round. Especially after that handjob earlier.
Without some serious stimulation and excitement, I can't go any further...
But after that comment, Matsuri finally seemed to get serious. I thought she was about to unleash her legendary skills, but no—she's still just messing around.
Perhaps it was just my imagination, but she seemed subtly troubled...
Well, "troubled" was certainly an apt description of the situation; I was feeling rather flustered myself.
When I looked at Matsuri again, I saw her earnest expression as she diligently moved her hands.
Whether it felt good or not aside, her intense effort was unmistakable.
As I watched her intently, I suddenly realized how aroused I was becoming. It was strangely thrilling.
No way... my sassy little sister is actually working so hard on my penis...
And somehow... she's adorable. Wait, has my younger sister always been this cute?
"Ah..."
Matsuri let out a soft sound.
Did she notice how much harder my penis had become?
This was embarrassing too. It made me feel like some perverted hentai, getting so obviously excited by my own younger sister.
...Huh? Could this be her technique?
Deliberately acting clumsy to heighten arousal...
That's crafty—way too crafty.
As I marveled at Matsuri's skill, Miki, who had been quietly observing the situation, leaned over and whispered in my ear.
"...He's rock-hard, isn't he? Harder than he was when I did it?"
S-she sees right through me...
My face burned with shame.
My penis became hypersensitive, and even the slightest touch sent me spiraling toward climax.
But the thought of actually coming like this—being teased like this, and by my own younger sister no less—made me feel even more embarrassed.
I can't let this happen. I want to come so badly, but I have to hold on.
Matsuri wasn't working, so I resigned myself to having Miki-chan casually finish me off.
Right, that's perfect.
Summoning the last shred of my rationality, I tried to regain my composure.
Then, Miki moved behind Matsuri and whispered something in her ear.
"Huh?" Matsuri made a brief, reluctant face, but she listened to Miki until the end without protest.
What the hell...?
Just as I was wondering, Matsuri knelt before me, her eyes meeting mine over my erect penis, looking up coyly.
...Ugh, this is...
Her large, round eyes framed a small, still-childish face.
Let me be clear: I am absolutely not a lolicon.
Now that I think about it, I realize I've probably come from loli-type scenarios more often than not, but I'm definitely not a lolicon.
At least, I don't think so...
Matsuri's movements remained awkward, but the visual effect amplified my arousal exponentially.
As Matsuri worked her hands diligently, glancing up at me with a coy expression, I foolishly found her adorable.
The moment that thought crossed my mind, a sudden wave of impending ejaculation surged through me.
"Ah, something's coming out..."
A copious amount of pre-cum dripped from the tip.
Matsuri curiously scooped it up with her finger and spread it across the glans.
The pinpoint stimulation made my hips jerk involuntarily.
"...Oh?"
Seemingly grasping the situation, Matsuri continued to spread the pre-cum across the glans with the pad of her finger, tickling it.
In rhythm with her movements, my penis twitched repeatedly, as if politely responding.
This... this is bad. The stimulation is too intense.
Damn it, if I come from this teasing touch, Matsuri will mock me mercilessly, saying something like, "You came while we were just playing? How hilarious!"
And Miki... she'll label me as a pervert, not just a guy with premature ejaculation, but a complete hentai—her older brother who embarrassingly climaxed in front of his younger sister.
This isn't working. I have to hold on. I need to hold on.
The problem is purely psychological. If I can just distract my mind somehow...
Gritting my teeth, I hastily averted my gaze from Matsuri and focused on the calendar on the wall.
I resorted to a desperate measure to divert my attention: adding up the red numbers on the calendar.
At first, it seemed utterly pointless, but surprisingly, it worked. My penis narrowly avoided detonation.
At the same time, fortunately, Matsuri's fingers slipped from the glans and began squeezing the base of my shaft instead, for some reason.
Whether intentional or not, this change in pressure was enough to stave off the impending explosion.
But my moment of relief was fleeting.
Miki circled behind me again, her breath tickling my ear.
"Look at Matsuri-chan, isn't she cute? Pay attention!"
Her sweet whisper erased all traces of the calendar numbers from my mind.
Instead, Matsuri's face reappeared in my field of vision.
Miki was pressing down on my head from above, forcing me to turn my face toward Matsuri.
"Hey, big brother? You're gonna come soon, right? Are you gonna let your younger sister touch your penis? Are you gonna do it? Come? It's okay. Come. Whenever you want, you can let it out on your hand. You can let as much as you want on Matsuri's hand, okay?"
My mind was already completely boiling with excitement.
Miki's whispered voice was automatically converted in my head and replayed in Matsuri's voice.
"Come on, big brother, let it out? Let the white stuff out? Let it drip, drip, all over Matsuri's hand?"
I couldn't take it anymore.
Just then, Matsuri, judging that the base of my penis wasn't working well, slid her hand back up to the tip.
The moment her clumsy fingers slowly traced the edge of the glans, my penis erupted, spilling its seed forcefully, just as Miki had told me.
