The Heat That Won't Fade
“You bastard… hngh…♥ Why the hell… ah, ahh…♥ Why’d you have to touch my sister too…!”
I couldn’t help but take a step back. But the moment my back hit the wall with a soft thud, I realized there was nowhere left to run. The living room was sweltering. The air conditioner was blasting, yet my body burned like it was on fire.
“Ah, ugh…”
The wet, obscene sounds of flesh slapping together filled my ears. Right in front of me were two naked bodies—my sister and Kim Do-hyun. They were tangled together on the sofa, completely exposed, moving as one.
“S-stop… Stop it already…”
My words didn’t reach them. Or maybe they just pretended not to hear. My sister kept glancing back at me, her lips twitching like she was fighting a smile. That expression only made the anger in my chest flare hotter.
“…Fuck. Ah, fuck… Fuck!”
Kim Do-hyun didn’t even bother hiding his grin. That smug, nasty little smirk of his. My chest felt tight. Everything about this situation was pissing me off. My sister ignoring me completely, the two of them fucking right in front of me like they wanted me to see. Their moans, the way their bodies moved—it all stabbed at me.
“…Haa, ha… haaah…”
My breathing grew ragged. I couldn’t think straight in this heat. I turned around and ran. I just wanted to get out of there. I didn’t want to see my own sister like that. Because she was my sister… because she was family…
“Haa, ha! Hoo, haaah…!”
By the time I came to my senses, I was already home. I bolted straight to my room and threw myself onto the bed.
“Ha, fuck… fuck…”
Frustration boiled up inside me—toward my sister and toward Kim Do-hyun. What kind of weakness did she even have that he could exploit? But she didn’t look like she was being forced. That only made it worse. How could she sleep with that pathetic loser without any blackmail involved?
“…She’s lost it. She must’ve gone crazy. Otherwise, how the hell could she do that with a loser like him…”
My lips stung. I’d bitten them without realizing. The metallic taste of blood spread across my tongue.
“Ha, hoo… haa, haaah…”
It was too hot. The blanket only made it worse. I kicked it off. Even my clothes felt suffocating, so I started stripping them off one by one.
“Nngh…”
The image of their bodies kept flashing in my mind. That wet, rhythmic sound—schlick, schlick, schlick.
“Ha… haaang…♥”
I wanted to forget it. I desperately wanted to erase it. But the more I tried, the more vividly it burned into my brain.
“……C-crazy… Everyone’s… gone insane…”
My hand kept moving. With every stroke, the self-loathing grew stronger. But I couldn’t stop. The pleasure flooding between my legs was stronger than the guilt.
“Fuck, fuck… you bastard…!”
Kim Do-hyun’s face surfaced in my mind. I wanted to kill him, but at the same time my stomach clenched with unbearable pleasure.
*
It was complete chaos. I really did keep going until I nearly passed out. My fingers were swollen and soaked. The sheets were drenched like I’d wet the bed. I must’ve fallen asleep like that about an hour ago.
When I woke up, my head felt clearer. But the moment I opened my eyes—
“…Fuck.”
A wave of shame crashed over me, far worse than before. The bed was a mess, and my naked body was still hypersensitive. Even the slightest brush against the sheets made me twitch.
“Ah, fuck… This is so messed up…”
I felt pathetic for running away like that. Why couldn’t I have just said something properly? I should’ve told my sister exactly what kind of bastard he really was.
“Haaah…”
My hand drifted downward again. Because I barely grew any hair down there, it was smooth and slick with everything I’d already spilled.
“…You bastard, hngh… Why… ah, ahhn…♥ Why’d you have to touch my sister too…!”
I’d seen it with my own eyes. They weren’t just pretending. They were completely joined, moving together like they belonged to each other.
“…Is it because of me…?”
If he’d wanted to, he could’ve done it plenty of times by now. But I’d always pushed him away. Eventually he stopped trying to take my panties off and started just groping my chest or licking me there instead.
Schlick— schlick— schlick—
“Hngh, hngh…”
My fingers slid into the still-wet heat. They were nothing compared to his cock, but they still sank deep inside me.
Twitch, twitch—
“Ah, ahh…”
My insides clenched around them. The thought that my body was acting so lewd made my head spin.
“…It’s all because of that bastard. That asshole… even laid his hands on my sister, damn it…!”
My thoughts were a mess. My head, my heart, my body—none of it made sense. I couldn’t sort any of it out. Everything just kept swirling around.
“…Everything’s… his fault, that bastard…”
My teeth ground together. I couldn’t do anything about this suffocating feeling.
“Hoo…”
I needed to clean up first. Mom would be home soon… and my sister still wasn’t back. Was she still with him? Still doing that with Kim Do-hyun…?
“Haa…”
The panties I’d thrown off earlier were already soaked through. Putting them back on felt gross, but I didn’t have much choice.
“…God, this is so annoying.”
I hated how much I kept thinking about the two of them. But she was my sister. My family. Of course it bothered me that she was tangled up with that loser. That’s why I couldn’t stop thinking about it. I decided to accept that explanation.
Vrrr—
A short vibration. My phone was ringing. My hand reached for it automatically.
It was a message.
“Huu…”
I checked the name and tossed the phone away again.
“Haa…”
Of course it was her. There was no way those two would contact me while they were still together. The thought made me feel a little pathetic, and my mood sank even lower.
Vrrr— Vrrr—
The phone vibrated again. This time it was a call.
“…Seriously.”
I glanced at the screen. Choi Ji-young again. I didn’t feel like answering, but the constant buzzing was getting on my nerves. I almost turned it off, but in the end I picked up.
—Yah! Why aren’t you answering your phone?!
“…What.”
—It’s been three days since I last heard from you and you’re still acting like this? I was about to head to your house, you know~
“So what do you want.”
—…Did something happen? You sound even crankier than usual.
“I’m hanging up.”
—Ah, why! Yah~ Let’s meet up for once, yeah?
“…It’s a hassle. I’m tired. Let’s do it another time.”
It wasn’t a lie. I really was tired and didn’t want to go out.
—That’s too much! Our Eunji’s changed so much!
I could smell alcohol through the phone. I was about to hang up when I let out a long sigh instead.
“…Where are you.”
—Kyaa! You’re coming?! Eunji’s coming~ The place is, um… I’ll send the address on KakaoTalk! Hurry!!
Beep— Beep— Beep—
“Haa…”
I’d been cooped up at home for days. I needed some fresh air. If I stayed any longer I’d probably end up touching myself until I collapsed again.
“Hngh…”
Now that I was actually going out, it felt annoying again. I stared at my underwear and hesitated for a second before just grabbing whatever was on top. I threw on the pants and t-shirt I’d tossed aside earlier.
The address she sent wasn’t far—just a short taxi ride away.
“…So that’s why she called.”
I wasn’t great with alcohol or drinking parties, but Choi Ji-young knew that and still invited me. And she’d chosen a place close to my house. That made it harder to refuse.
I flagged down a taxi. Traffic was slow because of rush hour, and the meter had already passed the base fare by the time I arrived. It put me in a slightly bad mood.
“Hoo…”
The street was packed with people. The smell of alcohol and cigarette smoke hung in the air. It wasn’t exactly pleasant.
“Yah! Park Eun-ji!!”
Among the crowd, I spotted a few familiar faces—friends I’d known since elementary school. The ones everyone called my “ride-or-die” crew.
“…What? Why are you all here?”
They’d scattered after graduation—some to university, some to jobs. They’d been making a fuss in the group chat about meeting up when everyone was free, and somehow they’d all gathered in one place.
“It’s vacation~ And the ones who are working have weekends off, so we all decided to meet today~”
Choi Ji-young explained with a cigarette in her mouth, her face flushed red. Come to think of it, my sister was on break too. She’d come home recently. They’d even picked a spot near my house so I wouldn’t complain about the distance.
“…You could’ve just told me.”
“Ha! How can I when you’ve been so cranky and ignoring everyone lately?!”
“…Anyway, I came.”
“I’m so grateful! Should we bow or something?!”
Choi Ji-young’s sarcastic remark didn’t really bother me.
“…Get your face out of here. You reek of smoke.”
“Yah! Did you guys hear that?! Park Eun-ji says stop smoking, so put them out right now!”
“Aish, this is embarrassing. Shut up already.”
After that came the usual small talk. Everyone seemed to be doing fine.
“Now we’re just waiting for one more person, right?”
“Who else is coming? I thought everyone was already here.”
I looked around again. It really did seem like everyone who was supposed to show up had arrived.
“Ah, isn’t that a taxi over there?”
A taxi pulled up right where we were standing. Everyone turned to look.
“Yah! Kim-jjin!!”
“……”
It was too dark to see the face clearly.
“Kim-jjin! How could you be later than Eun-ji!”
Thud, thud. That familiar gait approached us.
“…Who invited him?”
“Huh? I did, obviously~”
Choi Ji-young puffed out her chest and shrugged.
“Our Eunji can’t handle her liquor, so of course we need her personal shuttle Kim-jjin, right? Isn’t that right?!”
“Ah… yeah.”
I nodded half-heartedly. But the moment his sticky gaze swept over me from head to toe, my body started burning all over again.
