Playing Games with My Little Sister (1)
I had just gotten home. “I’m back~”
When I stepped inside, my adoptive younger sister was sitting in front of the TV, completely absorbed in a console game.
Ayeon seemed to have fallen head over heels for the console she’d bought recently. She spent every afternoon planted in the living room like this, glued to the screen.
Even the sight of her back while she focused on the game was unbearably cute.
“Ayeon, you’re playing again?”
Hearing my voice, she turned her head just enough to check it was me before answering.
“…Mmm!…”
“Is it really that fun?”
“Mmm..! Just a second..!”
Ayeon whipped her gaze back to the screen and locked in again.
Tap-tap-tap!
She hammered the buttons with fierce concentration until the word CLEAR flashed across the screen.
“Yes! So? I’m totally good, right?”
“Ahaha… Yeah! You sure are~”
“…Hmph. You don’t even know what you’re looking at.”
Unfortunately, she was right. I had no clue what was happening.
I never really played games.
“Sorry!”
Still, watching her so passionately focused made it look genuinely fun. Maybe I should try it myself?
“Um… Ayeon! Oppa wants to play too. Will you teach me?”
“Mmm…. Okay! Then let’s not play this one. Let’s play a game we can do together!”
“A game we can play together? There’s something like that~”
Ayeon fiddled with the menu. Soon the screen showed two characters staring each other down.
The big “VS” in the center made it obvious—this was a fighting game.
I was supposed to fight Ayeon?
I was terrible at games…
Ayeon held the controller out to me and patiently walked me through every button, one by one.
She really was sweet.

Move the stick to choose your character… This is attack, this is jump, crouch, block, movement…
The controls were simple enough that I picked them up quickly. The problem was the combo system—every move had different button combinations and I kept forgetting them.
Ayeon kept explaining, but sitting beside me must have felt awkward. She suddenly stood up.
Thump!
Without warning, she dropped herself onto my lap and resumed teaching me the moves from there.
“So… this does a kick! This is a right punch!… And then… um… also…”
Tiny Ayeon had nestled right into my arms, chattering away with passionate energy as she taught me. It was adorable.
My little sister really was the best.
The new position made teaching easier for her, but my concentration was rapidly deteriorating.
Ayeon’s hair smells like shampoo… Is she using a different brand than me?
Strictly speaking it was the same shampoo, yet it carried a mysteriously softer, sweeter scent.
I rested my chin on top of her head, breathing in that scent while I “listened to the lecture.”
“And finally this is the counter attack! …Oppa… you are listening, right..?”
“…Huh? Yeah! Of course I’m listening!”
“Hmph…. You totally zoned out! Fine, I’ll assume you know everything and we’ll start right away, okay?”
Uh… knowing something in theory and actually pulling it off in real time were two very different things, weren’t they?
It had already begun before I could protest.
Was it just my imagination, or did my sister’s eyes just sparkle?
I decided to stay calm. The moment the match started I fired off a long-range projectile to keep her from closing in.
“Don’t use cheap moves like that!”
But… you’re the one who taught it to me, little sis…
As she approached I kept back-dashing, blocking or countering when I could, and throwing out another projectile whenever I gained distance.
Timing the counters properly was harder than it looked.
When Ayeon’s character launched mine into the air, she immediately chained into a combo that kept me from recovering.
“Haha! How’s that? This is the real Kim Ayeon! How does it taste?”
“Oppa isn’t dead yet.”
Even as I said it, she was nearly at full health while my character looked like he would die from a stiff breeze.
I finally landed one solid kick and knocked her down. I tried to follow up with the combo I’d just learned, but my timing was off.
Ayeon stood back up and finished me off with another long-range attack.
“Ugh… I guess there really are no upsets!”
“Obviously! All I do is eat and play games! How could Oppa possibly beat me!”
“That’s just bragging, Ayeon! But Oppa is proud of you…”
Oops. I hadn’t meant to say that last part out loud.
“Hmph! Rematch! I’m going to punish you, Oppa…”
“Sure… It’s actually more fun than I expected?”
“Hehe, right? I told you it’s fun! Playing together makes it even better!”
“Aren’t you just enjoying bullying a newbie?”
“That too… Hehe.”
While she set up the next match, Ayeon pressed herself even tighter against me, readjusting her position on my lap.
“Hmm… You’re even fixing your posture. Do you really need to look that serious when you’re up against a total beginner, Ayeon?”
With an utterly solemn expression, she answered.
“Of course! Even a tiger uses its full strength when hunting a rabbit!”
So I was the rabbit, huh…
Unfortunately this position was incredibly uncomfortable for me.
The way her butt was pressing directly against my crotch created a strange, persistent stimulation that kept distracting me.
Still, I had gained some feel for the game in the last round.
My counter timing had sharpened considerably, so Ayeon could no longer rush in carelessly. She must have noticed me looking for counter opportunities and started attacking more cautiously.
But every time she attacked, she tensed her body, causing her hips to wiggle.
That girlish yet firm, perfectly sized butt kept rubbing against my cock, and my cock inevitably began to swell.
Focus on the game… If I get hard, I’m finished…
The thought of my little sister noticing my erection while she sat on my lap made my head spin.
Last time, when I’d done something weird while brushing her teeth, she hadn’t seemed to mind much. But this time she was directly feeling my cock, so there was no way she wouldn’t realize.
Fortunately, Ayeon still didn’t seem to notice the hard shape pressing against her butt.
One hit. Two hits. Three hits. Every impact sent another jolt of pressure through my cock and pushed me closer to the edge.
This round too, her character was almost untouched while mine was on death’s door.
Still, I had landed more hits than last time. Progress, even while being physically attacked by her ass.
My character collapsed after taking the final blow.
Ayeon bounced excitedly on my lap, and that motion was unbearable.
She wasn’t literally jumping, but the way she kept wiggling her butt was driving my cock insane.
Was she getting revenge for the way I’d teased her yesterday…?
But her face looked far too innocently happy for that.
“You can be this happy about mercilessly beating up a newbie, huh, Ayeon…”
Yet my awareness of her ass only grew stronger. No matter how hard I tried to focus on the game and ignore it, the skirt she wore today was ridiculously short. Enduring the direct skin-on-skin stimulation of her bare thighs and panties sliding over my cock was pure torture for a man.
She was even wearing stockings that seemed deliberately chosen to heighten the sensation. It really felt like she was doing it on purpose.
If she stayed on top of me any longer, it would be stranger if she didn’t notice.
It was time to say something.
“Ayeon… Oppa’s legs are getting tired. Aren’t you going to get off?”
“Nope! I’m not! Do you hate me sitting here, Oppa..?”
“No… It’s not that I hate it…”
It really felt like I was about to burst.
Pre-cum had already soaked through my pants.
Ayeon, riding a winning streak, wiggled her hips from side to side in delight.
If this continued even a little longer I was going to cum. Was my little sister intentionally grinding her ass against my cock?
She kept giving my shaft stronger and stronger stimulation.
I couldn’t hold back anymore.
I wanted to cum all over Ayeon’s ass just like this.
Once my pre-cum coated her soft skin, her movements became even smoother and slicker.
I’m sorry, Ayeon. It looks like I can’t be a good big brother after all.
To keep her from noticing, I decided to give her a different, much stronger stimulus.
I’m sorry, Ayeon. You can resent your pathetic older brother…
I pressed my cock firmly between her cheeks while wrapping an arm around her head, locking the little devil in place.
“Kek!… O-Oppa…”
Maybe because her neck was being squeezed, her movements grew smaller.

“No… kek… Oppa… wait a moment..? I can’t breathe…”
No matter what Ayeon said, I stayed silent and simply kept rubbing my cock against her ass.
Smack♡! Smack♡! Smack♡! Smack♡!
The lewd sound of her bare ass slapping against my pelvis echoed.
With one hand I pulled down the hem of her tiny skirt, trying to contain the mess so my cum wouldn’t splatter everywhere.
Spurt♡! Gush♡! Gush♡! Gush♡!
Thick ropes of my semen painted her ass, panties, and the inside of her skirt.
The nasty scent of my cum filled the air, but I decided to pretend nothing had happened.
Still choking her lightly, I casually attacked her character on screen.
Maybe she would think I had just used a cheap trick to win the match?
If it weren’t for the warm, sticky cum now coating her ass, she might have believed it.
Actually, after all that hip-shaking, there was no way she hadn’t noticed.
“Ugh… ugh… That’s too mean…”
Yet Ayeon didn’t seem to dislike having her neck squeezed. She barely complained and simply continued playing the game while I held her in place.
This only made me want to torment her even more.
What exactly was she expecting from me…?
