The View Through the Crack (8)
The sight of Jisu through the crack in the door was utterly obscene. Those seductive moans, the way her hips trembled and twitched with every breath. I knew she was taking a half-day today, but… she could have at least told me she was coming home. Did she think I’d already left the house?
‘Holy fuck…’
I’d woken up hard to begin with, but watching my older sister pleasure herself made me throb even harder. The back of my head was tingling. I’d only meant to peek at the panties I could see through the gap, but I’d stumbled onto something far more dangerous.
“Haa…”
“…!”
When she switched the hand holding the toy, I caught a glimpse of it. Just for a split second, but it burned itself into my brain far more clearly than the panties I’d seen at dawn. The petal-like folds guarding her slit, the transparent nectar dripping steadily from her entrance. The blurry image I’d carried from that early-morning encounter suddenly sharpened into perfect focus. No—this was nothing like when it had been closed.
‘I’m so fucked…’
By the time I came back to my senses, my boxer-briefs had pitched a full tent. I yanked the waistband down, freeing only the thick, heavy shaft.
“Ahng…”
“…!”
Apparently that wasn’t enough for her. Jisu yanked her top off and tossed it aside. Too impatient to remove her bra, she simply shoved her hand underneath the cup and began moving with even greater urgency. I genuinely felt grateful that I was the one seeing this.
“Good… right there…”
It wasn’t a dildo. The low, buzzing hum told me it was a vibrator. It wasn’t even touching me, yet I could feel my own cock twitching in sympathy.
“……”
My eyes stayed locked on her in a trance while my hand worked my shaft. Jisu was lost in ravaging her own body. Her bra had shifted, pushing one breast up, and the sight of that flushed pink nipple made my mouth water. An expression I could never have imagined on the usual Jisu. I etched every detail into memory—the ragged breaths, the deep crimson blush blooming across her cheeks.
“Haaauu…!”
She set the toy aside and plunged her fingers inside herself. The barrier was gone now, and the slick evidence of her arousal left lewd, glistening trails on both thighs. Her hand moved faster, more desperately, and mine matched the pace.
“Haa… Haa…”
This was the first time I’d ever heard those wet, squelching sounds in real life. The only noises I knew were the shameful ones I made when I jerked off alone. How could the exact same act feel so completely different just because of gender? A woman’s body really was a mystery.
“Hup…!”
She clamped the hand that had been inside her over her mouth as her hips jerked violently. Did something just squirt out, or was that my imagination?
‘Ah, I’m done for.’
Watching Jisu cum pushed me right to the edge. I rose onto my tiptoes and hurried back to my room. Getting caught watching porn would be one thing, but getting caught spying on my sister masturbating? I might actually jump off the balcony. It was honestly impressive that the panty-thief brother hadn’t. At least he’d gone all the way and fucked his own sister… Lucky bastard. Wait, was I jealous? Or was I not jealous? Was I jealous?
“……”
In the end I couldn’t hold back. I crawled into bed and pretended to be asleep. There was a bit of precum on my hand, but since I hadn’t actually cum, it probably didn’t smell. The urge to just push her down like that panty thief kept growing stronger inside me.
Shaaaaa—
She must have gone to the bathroom; I could hear water running. Should I go out now, or keep pretending to sleep? If I walked out right now, there was a hundred percent chance Jisu would realize I’d seen everything. But continuing the sleeping act any longer would be too suspicious.
‘Pussy…’
No, this wasn’t the time to be thinking about that. Maybe I should have just blown my load against the door. I really had to make sure I didn’t slip up and say something stupid.
“……”
I pulled on my pants and stepped out, casually heading to the fridge for a cola. Jisu must have only cleaned up the evidence on her body, because she came out sooner than I expected.
“Whew… Oh, you’re awake?!”
“Huh? Yeah… I heard the water running.”
She’d come out of the bathroom only to duck back inside. Then she poked just her head out.
“Did I wake you?”
“No. It was about time for me to get up anyway…”
How could she wear that filthy expression while touching herself and then face me with a perfectly normal one? That kind of casual attitude could only exist if she had no idea I’d seen her.
“Did you eat breakfast?”
“No. I ate something at dawn and went straight back to sleep.”
“What are we going to do? You must be hungry.”
“It’s okay. I’m only a little hungry.”
“Want to go out and eat?”
“Sure. When did you get home, Noona?”
“Around one o’clock? I got back then. They told me to eat lunch and head out, but you were sleeping so soundly I didn’t want to wake you.”
“Ah, I see.”
“…Um.”
“Yeah? What?”
“Can you turn around for a second…? I forgot to bring clothes in with me.”
“……Ah. Okay.”
No wonder she hadn’t come out—she’d gone in without even putting on panties. Normally Jisu would walk around in just her underwear, but after what she’d just done, she was probably too embarrassed to let her pussy feel the open air.
“All done~”
Recalling the scene from earlier, I sat back down. It felt like I wouldn’t be able to look her in the eyes anymore. Even during our conversation I’d been staring at the empty space beside her instead of at her face. That said everything.
‘Just go down already…!’
The problem was my cock. Normally if you stopped halfway it would soften, but right now it refused to go down and kept pitching a tent. I needed to focus on something else, fast. Or maybe rub one out in the bathroom.
“This outfit really is the most comfortable.”
“You wear that to the office too?”
Jisu had changed into something very casual—a white t-shirt and black dolphin shorts. Why did it have to be an oversized tee again? If she leaned forward even slightly, you could clearly see the white bra underneath.
“No way. If I did that, people would start thinking all the MZ-generation office workers dress like this.”
“Is it that bad?”
“Yeah. It’s not a field job; it’s office work, so I can’t dress too comfortably. I feel like it ruins the whole atmosphere, so I avoid it.”
“I see.”
Well, clothes do set the mood. It made sense. Like how you wear a full suit or at least a blazer to an interview unless it’s a very special case.
“Jiyun. So you really haven’t eaten.”
“I haven’t.”
“Then let’s just order delivery. Noona’s buying.”
“Nice!”
Anyone with siblings knows this, but just because you live together doesn’t mean you’re glued to each other all the time. You can retreat to your own room whenever you want and live as if you’re living alone.
This guy really sounded like he might actually call the cops. The tone was so serious it was starting to scare me.
Looked like the Pa-ttak deleted it after seeing the comments. First time I’ve ever seen a Pa-ttak delete their own post. The public opinion was treating him like a pathetic loser, but he probably deleted it because he was actually worried about getting reported.
The apology post went up right after. For a Pa-ttak, this was an unusual move, and it only made him seem more terrifying. It meant everything he’d posted before wasn’t just a character—he was dead serious. Scary stuff.
I should probably delete this. I almost posted it without thinking.
[Cancel][Post]
I agonized for a long time over whether to hit post. Posting felt like I’d get caught immediately. Not posting felt like I might accidentally say something out loud. Still, secrets like this need to be released somewhere or they’ll eat you alive.
“Jiyun, delivery’s here. Can you get it?”
“Yeah.”
Jisu called for me and my time to hesitate ran out. Whatever, screw it. I’m posting it. If she says anything, I’ll just gaslight her and ask how she could possibly know. …Thinking about it, I really am trash.
“Looks delicious~”
“We ordered from here last time and it was good.”
“Didn’t I tell you about this place?”
“Yeah. You did. Looks like we’ll be ordering from them a lot from now on.”
We’d ordered from the pork cutlet place Jisu had recommended. Luckily she was here with me, so even if the post got deleted there was no way it would be because of her. I just hoped the Pa-ttak wouldn’t delete it. He usually only deletes obvious advertising accounts, so it probably wouldn’t get taken down for a while—
What the hell? It never gets this many comments normally.
I wondered why there were so many comments. Looked like the panty-thief-brother story had spread to other galleries in the blink of an eye. It had spread so far that our gallery, which usually hovered around the 300th rank in activity, had shot straight up to 40th.
“What are you staring at so hard?”
“It’s YouTube, YouTube. I have way too many notification subscriptions.”
“Ah, I see—”
Vrrrrrr vrrrr vrrrr vrrrr vrrrr
“…?”
This time an enormous vibration erupted from Jisu’s phone. Was it a gallery-related alert?
“What’s that sound?”
“Huh?! I got a YouTube notification too? Must be a bug!”
“Ah, gotcha.”
It was probably a keyword alert for the gallery. For now, I decided to play dumb.
Vrrrr. Vrrrrrrrr.
“…We both need to turn our notifications off.”
“Right…?”
How long could we keep pretending not to know? At the very least, I hoped she would never find out that I had watched her.
