I Saw My Sister Masturbating (2)
The head moderator of the Friendly Siblings Gallery, also known as the Incest Gallery, almost never posted anything herself. The only times she ever showed up were to delete fake threads or update the notices. I used to wonder sometimes what kind of person would create a gallery like this, what the owner of such a shady corner of the internet even looked like. I was curious why she was so obsessed with things being “real.”
I never imagined it would turn out to be my own sister…
The Ju-ttak was usually active after nine at night. During the day, the Pa-ttaks ran wild, spamming every kind of perverted post imaginable. No wonder all those threads vanished the second my sister got home from work. The reason my own post got deleted immediately was because today was her day off.
Click. Beep-beep-beep.
The sound of the door lock. I’d been so focused on her computer screen that I hadn’t even noticed.
“What are you doing in my room?”
“Uh… I was just about to turn the light off…”
“I told you I’d be right back so you didn’t have to. Here, eat this.”
“Yeah… thanks…”
She handed me the cup of army stew ramen and the mask I’d asked for. Thankfully it looked like she hadn’t caught me looking at her computer.
“……”
“What? Do I have something on my face?”
“No. Nothing.”
Now that I knew her secret, everything about her looked different. My goal had always been to be as put-together as my sister, yet here she was—the actual ruler of a trash bin overflowing with deviant sexual fantasies. I couldn’t decide whether I should be impressed or horrified.
And why the hell was she wearing that thin-strapped tank top?
“Don’t touch the light in my room.”
“Then you turn it off.”
“Shut up and go to your own room already.”
“Fine.”
I went back to my room, but kept an eye on her from a distance. She didn’t seem to be acting any differently. She was completely normal.
Goddamn it…
Maybe my sister was actually a pervert just like me? There was no way a normal person would run a place like that. And it wasn’t like she just collected random posts—she only kept the ones that were verifiably real. She had to be a massive degenerate.
Damn. The image of my sister naked that I’d barely managed to forget was coming back in crystal clarity.
What if I asked her to take my virginity—
Yeah, right, you idiot. I wasn’t some middle-schooler who’d just hit puberty. I was a grown adult who knew everything there was to know. What the hell was I even thinking? No matter how you looked at it, she was my older sister.
[Wanna come see how fucking huge my little brother’s dick is?]
It wasn’t about doing it with her. It was just the art style and the harem genre that got me going. Today’s pick was this one.
“You’re back?”
“Did you eat?”
“I grabbed something from the fridge with Mom.”
“What? You didn’t even leave me any soup?”
“Of course not. I only ate once.”
“You should eat more.”
“I took a lot. You’re the one who didn’t eat.”
It was late at night when Mom finally came home. Why did adults always work six days a week? Both my sister and I were working and paying rent now. I still didn’t understand it. It felt like she should be able to take it easier at her age. But I’d heard somewhere that if older people stopped working completely they’d get lonely, so I couldn’t exactly tell her to quit. Besides, she seemed to enjoy chatting with her coworkers while she worked.
“Here.”
“Whoa~”
My favorite—cheese sticks. In my opinion, they were the ultimate food, letting you experience the rich, savory taste of cheese and the crisp crunch of the fried coating at the same time.
“You kept begging, so I bought some.”
“Love you, Mom~”
“Give me one too.”
“Here.”
“Mom’s home~?”
“…!”
The moment Mom and I were about to share the cheese sticks, my sister came out of her room.
“Hey, give me one too.”
“…Here.”
“Mmm~ Stealing it from my little brother makes it taste so much better.”
“Ugh…”
Normally I would have gotten mad that she stole my cheese stick, but right now I didn’t have the mental bandwidth. She was a fully grown adult woman, yet here she was wearing nothing but an oversized shirt with no bottoms. Pink panties.
“Jiyun~”
“What.”
My sister called my name in that cutesy voice she only used when she wanted something.
“Wanna split the last cheese stick in half?”
“Why are you acting like you’re in charge…”
“Because there’s only one left~”
“Did it ever occur to you that the last one is supposed to be mine?”
“Aww~”
“Gross.”
I pretended I couldn’t win and broke the last one in half. Fine, whatever—just please cover up your panties. It wasn’t completely obvious, but the faint outline of her ass was visible, making it look like I was the one sneaking peeks.
“Wow, these taste really good when you haven’t had them in a while.”
“I feel like I could eat two every single day.”
“That wouldn’t be good for you.”
“I know. That’s why I don’t buy them every day.”
Of course, the real reason I didn’t buy them was because it was a hassle. The burger place in our neighborhood didn’t sell cheese sticks. I could pick some up on the way home from work, but by then everyone knows you just want to get home no matter what.
“All done.”
“……”
Once she finished eating, my sister leaned her whole body against me, completely relaxed. I had no idea why she did this, but it had become a regular habit at some point.
“You’re heavy.”
“Carry me to my room, pleeease.”
“Yeah, right.”
Until this morning, it had been the kind of silly joke I could mostly ignore. But after finding out she was the Ju-ttak of the Incest Gallery, every little thing she did looked intentional. Like she was deliberately lowering her guard around me. Was this what being the head of the gallery did to a person?
“Huh? Did you just push your sister away?”
“Yeah.”
I hadn’t really pushed her—just lightly moved her off me. She’d probably never realize in her entire life that her ass had been pressed against my thigh and crotch.
“I’m going to bed. You two should sleep soon too.”
“Good night.”
“Night~”
It was past eleven. The living room lights were off, and the only light came from the crack under my sister’s door.
If I posted [My sister is the Ju-ttak of the Incest Gallery], she’d figure it out instantly. She still wouldn’t know it was me who posted the original thread, though. My fingers itched to type it, but I forced myself to stay quiet. At least half the fun—
“You awake?”
“Jesus, you scared me.”
Once again, she flung my door open and walked straight in. Still wearing that bottomless look, she plopped down right next to me. Good thing I’d already taken care of business earlier.
“What do you want?”
“Let’s watch a movie.”
“A movie? What movie?”
“Sweet Tony. Everyone says it’s really good.”
“Never heard of it.”
I looked it up. It was apparently based on an English urban legend. The poster looked exactly like something my sister would love, and one of her favorite actors was in it.
“Is this guy the killer?”
“Yep. It’s super obvious. You’ll see once you watch.”
It wasn’t about Jack the Ripper, the real serial killer, but a barber serial killer. The fact that Jack the Ripper’s main suspect had been a barber made it even more interesting.
“I don’t have any speakers though.”
“Then how do you watch anything?”
“I use earphones.”
I didn’t want to advertise what I was doing, so I never bought speakers. Plus there was always the risk of accidentally blasting porn sounds through them.
“What? Then how are we supposed to watch a movie?”
“Um… wanna share the earphones half and half?”
“No, that’s uncomfortable.”
“Then we can just use your laptop. Let’s watch on that.”
“Oh, good idea?”
She went to her room and brought back her laptop. She still hadn’t turned off her light.
“Done.”
“Nice.”
It was an Apple laptop, so the speakers were excellent. No problems watching a movie at all.
“Why are you sitting over there?”
“Isn’t this how you’re supposed to watch it?”
“The screen’s too small. It’ll be uncomfortable. Come sit next to me.”
“Alright.”
I sat down beside her on the bed where she was leaning against the wall. Our bare skin kept brushing together, which made me hyper-aware again.
“It’s heavy.”
“…Give it here.”
I tried to hold the laptop between us, but she complained it was heavy, so I ended up balancing it on my lap. My legs were spread at a pretty wide angle, but it wasn’t uncomfortable.
[Aaaagh!]
[Guh!]
[Ugh]
[Gwaaaah!]
The protagonist, now fully awakened, began slaughtering people. The bodies were taken through a secret passage to the basement where his partner turned them into pies. Up on the first floor, customers happily ate those pies.
“Ugh, that’s brutal.”
“Maybe it’s worse because there’s no mosaic—”
At that moment, my sister leaned her head on my shoulder. I looked down, wondering what was going on, but she was still staring intently at the screen.
“Uh. My shoulder.”
“……”
She didn’t seem to hear me. She looked so focused that I couldn’t bring myself to say it again.
“……”
Instead, I slowly leaned my own head against hers. She didn’t say a word. Man, she was really messing with my head. Was this the dignity of a Ju-ttak?
[Wait…! I’m…!]
“……”
Near the end of the movie. Her t-shirt had ridden up so high that her panties were now completely visible. Even when I turned my eyes and stared openly, she kept watching the screen without reacting.
Hold on…
Only then did I notice the small white square peeking out from the edge of her panties. Wait, was that… what I thought it was? The thing she went out to buy earlier today?
I was losing my mind.
“Whew… That was fun.”
“Yeah… it really was.”
It was a musical film, so both the visuals and the music had been a treat. In more ways than one.
“What time is it…?”
“A little past two.”
“Time to sleep, I guess…”
“Good night.”
“Yeah. Night.”
As she stood up, she glanced down at her own panties and quickly tugged her shirt hem down. It was the first normal thing she’d done all night, and I felt both relief and a strange sense of disappointment. So she really hadn’t noticed. Thank god my suspicions were wrong.
“Hey, sis.”
“Yeah?”
“…Never mind. Sleep well.”
“You too~”
This time the back of her shirt had ridden up, leaving her ass fully exposed. I kept quiet, afraid saying anything would make things weird.
“Haa…”
Exhausted, I collapsed onto my bed. The warmth where we’d been sitting together still lingered.
“Sss… haa.”
I instinctively breathed in, catching a strange scent mixed in the air. The smell sent dopamine rushing through me like nothing else.
Early every month…
I guess I should start keeping track of her cycle.
