Was Sister Coming This Week?
Park Eun-ji’s pale body was like a blank canvas. And on that canvas, my marks were steadily increasing, one after another.
Thud— Thud—
“Ah, a little more!”
Park Eun-ji’s lower belly spasmed. Her abs, more defined than before, twitched and rippled.
“Hnn… slurp, suck. Mmmph.”
Her weak arms tapped at my head. She probably thought she was hitting me hard enough to hurt, but among all the punches I’d taken from her, this was the most ticklish by far. It was enough to make a small laugh slip out from between my lips.
At the sound of my chuckle, she flinched. She tried to scoot backward, but there was nowhere left to go. I pressed closer, pushing deeper inside her.
“Hnnk! Ha, hahk!”
I forced my legs between her tightly pressed thighs. The space between them was slightly damp as I pried them apart. Not just her thighs—the sheets beneath us were soaked through as well.
“…How much did you even squirt?”
The bed and sheets were starting to worry me, but my curiosity was impossible to suppress.
“W-what! Ha, don’t do that!”
Her reaction was delightful. Seeing Park Eun-ji flustered like this was genuinely entertaining.
“It’s fine, it’s okay—”
“Ha, it’s not fine at all!”
There was no need for me to smell the scent of her piss. That wasn’t my kind of kink, after all.
Wham—!
“…Ah.”
It was her knee. She drove it straight into my chin. For a moment, my head felt like it was rattling inside my skull.
“I told you to stop, you fucking bastard—!!”
Her voice rang in my ears. My vision went black almost instantly.
“Ugh, ughk….”
A metallic taste spread through my mouth. I must have bitten my tongue. The rusty scent of blood, something I hadn’t tasted in a while, made nausea rise in my throat.
“Ah… haaah….”
Light slowly seeped back into my darkened vision. Just as the blur cleared, Park Eun-ji’s fist filled my sight again.
Thud—!
The playful punches from earlier were gone. This one carried real weight, like she meant to crush my face.
“Ah… aaah….”
Stars sparkled in the sky. Just moments ago this had been my room, but now there was no ceiling—only a night sky glittering with stars.
“Y-you, you fucking bastard….”
Park Eun-ji’s face, barely visible, was flushed with shame. The embarrassed expression had been replaced by pure venom. Her breasts swayed heavily as she frantically tried to cover herself with the blanket again.
“Haa… If you mess around one more time….”
Her voice came out like she wanted to chew me up and spit me out. It was hard to believe this was the same girl who had been moaning under my touch just a little while ago.
“……Shit, that really fucking hurt….”
It had been a long time since I’d been beaten this badly. Probably not since I was a little kid who couldn’t control my strength. And yet, strangely, my mind felt clear. The anxiety about getting hit again only lasted a second. I wanted to remind Park Eun-ji exactly who she had just punched.
“…Park Eun-ji, you just hit me, ah, ugh!”
The taste of blood slid down my throat. I swallowed it down and was about to snap at her when I noticed she was suddenly busy. She yanked the sheet off the bed and started rolling it up in a hurry. The blanket she had been using to cover herself slipped down.
“…What are you doing?”
I just watched her, because I had no choice. Her sudden, frantic movements had left my brain struggling to catch up.
“……I said, what are you doing?”
She moved like she was in a panic. After rolling up the sheet and setting it aside, she started gathering the clothes I had stripped off her.
“Hey! What the hell are you doing?!”
She bundled everything together, then glanced at me once.
“Uh, uh! Hey! Hey!”
Park Eun-ji bolted out of the room. Naked. In the blink of an eye she reached the door and flung it open so fast it felt like less than a second had passed.
“…Shit, I’m fucked.”
The spot where she’d hit me was still throbbing. I nearly toppled sideways as I tried to stand. My balance was completely off. Any second now, my parents’ screams would echo through the house. Dad might even show up with a stick and beat the hell out of me.
…Park Eun-ji’s reaction had gone way beyond anything I’d expected. My mouth went dry. My hands and feet trembled from the shock of the completely unforeseen situation.
“…….”
It was quiet. Unnaturally quiet.
“Ah….”
A terrible suspicion grew in my mind. What if she had knocked out my parents too, just to get rid of witnesses?
“…I’m so fucked… shit.”
The atmosphere was getting weirder by the second. I had a bad feeling about this. Forcing my shaking legs to move, I followed the path Park Eun-ji had taken.
“Ugh, ughk….”
First, I pulled up the underwear and pants I had kicked off earlier. With unsteady, anxious steps, I left the room.
“……Mom? Dad?”
I still couldn’t make sense of what was happening. Step by step, I made my way toward the kitchen.
“…Mom?”
I called for her again. Once more, there was no answer.
Clatter— Bang—!
“Ah, fuck!”
At that moment, the front door slammed shut. I didn’t even have time to feel relieved. I rushed straight into the kitchen.
“Ah….”
Luckily, the kitchen was empty. But traces of a recent meal still remained on the table. A small note was tucked under a glass of water.
[Son~ Mom and Dad went on a date. We’ll eat dinner outside. Tell Eun-ji to take her time and head home later. Love, Mom.]
“…….”
I couldn’t tell if the timing was good or bad. What I did know for sure was that my parents had no idea what had just happened. It was a small comfort, but I clung to it as I headed back to my room.

“Haa! Haa! Haaah!”
My heart felt like it was about to burst. Maybe it already had. I was completely out of breath, and it felt like my heart was about to leap out of my throat.
“Haa, ha… hoo….”
My hands and feet were shaking. Not from anything else—just pure, soul-crushing embarrassment. The kind that made me want to die on the spot.
“Ah, fuck… that crazy bitch… that psycho….”
Honestly, it had felt good. The way his hands, mouth, and tongue had roamed over my body. It was my first time experiencing something like that, and the feeling was completely new. It was addictive. Like being pulled into a swamp. By the time I realized it, I was already in too deep to escape.
But still… how could he? It wasn’t anything else—it was that.
“Haa….”
I told him to stop. I said it over and over so he’d understand. And then I pissed myself. Right there on the bed. In front of Kim Do-hyun.
“……Fuck.”
It felt like my dignity as a human being had been completely destroyed. No, it had been destroyed.
“You crazy bastard… you should’ve known when to stop….”
Traces of him were all over my body. Bite marks and hickeys he’d left behind. He had sucked and bitten at me for so long that my skin still carried the faint scent of his saliva.
“Sniff, sniff….”
The spit had dried, like my body had been coated in Kim Do-hyun’s saliva.
“Haa… you fucking bastard….”
Shower first. I was way too wet down there to stay like this.
“Haaang….”
My body felt limp. It was the kind of exhaustion you only get after sprinting a hundred meters at full speed. My limbs trembled. I knew exactly why my body was still so worked up.
…Arousal. That’s what it was. The reason was too embarrassing to put into words.
“Haa… I don’t know….”
I didn’t want to think about it. Thinking only gave me a headache.
“Maybe I shouldn’t have brought this….”
I tossed the clothes into the laundry basket. The only thing left was the bedsheet. It was damp. The memory of getting scolded as a kid for “drawing a map” on the sheets flashed through my mind.
“Hoo….”
Why did I even bring it? I grabbed it in a panic because I was embarrassed, but why the hell did I take Kim Do-hyun’s bedsheet without any plan?
The washing machine would handle the laundry, but I had no idea what I’d say if Mom saw it and asked.
“…I never should’ve gone in the first place….”
Right. I was the idiot who listened to Mom like a complete moron and ran that errand.
“Ugh….”
All I could do was sigh. The sighs were getting deeper.
“Ah… I’m going crazy.”
I stood in front of the mirror. My reflection was a complete mess.
“Ah….”
Clear bite marks and bruises on my shoulders. Dark purple hickeys scattered across my breasts, even in places that weren’t easy to see.
“…I’m so screwed.”
It was a house full of women. I used to walk around half-naked without a care, but now I couldn’t even undress freely in front of Mom anymore.
“That fucking bastard… why the hell doesn’t he know how to hold back….”
I clenched my fists. …I did hit him pretty hard earlier, but still… I wasn’t some crazy bitch… Why was I even worrying about that asshole?
The anger wouldn’t go away. There was no time to vent it either.
Warm water. I stood blankly under the shower stream. The flowing water. The warm water washing over my body. The marks he left behind didn’t disappear. They stayed like scars, forcing me to remember what happened.
“…How am I supposed to face that bastard now….”
Maybe it was the hot water. My head felt dizzy. The steam blurred my vision, but none of this felt like someone else’s problem.
Drip— Drip— Drip—
The shower stopped. That was enough. My face looked even darker than before. Exhausted, I just wanted to close my eyes and sleep.
Water that hadn’t been properly wiped off dripped onto the floor. I didn’t have the energy to care.
“Hoo….”
My steps felt heavier than ever. I had never felt this weighed down before. My body was still damp. I collapsed face-first onto the bed.
“Haa….”
It was soft. The feeling of the wet sheets against my skin wasn’t unpleasant.
Vrrr— Vrrr—
“Ah, fuck!”
My phone was vibrating. A call. And I knew exactly who it was.
“Ah….”
My heart shrank to the size of a bean from tension. But when I saw the name on the screen, I felt an involuntary sense of relief. And at the same time, a hint of disappointment—
“…Bullshit.”
I answered the call anyway. The familiar voice came through the receiver.
“Yeah, what?”
- I’m on my way home.
“…So what?”
- So what? Ha! Listen to you talking to your big sister.
“Big sister, my ass.”
- My ass?! You little—!
“…Ah, shut up. Did you get on the bus? Was it this week that you were coming?”
- …Yeah. I got on, why!
“You’re the one who called, though?”
- Ah…… Right.
Even though she was shorter than me and had a smaller chest, she always acted like the big sister. Well, she was the older one, so… I guess that made sense. And somehow, that was part of her charm.
- It’s so hot on the bus….
“Hot? Why? My air conditioner’s blasting and it’s nice and cool over here.”
- Haaah… listen to you.
She started grumbling and rambling. For a moment, I forgot about everything that had happened earlier and just went along with the conversation.
- Ah, there’s a new café here.
“Where?”
- Right next to the terminal.
“Ah, the termi… nal?”
- Yeah. If I get off and take a taxi, it’s like five minutes? Maybe five minutes.
“Ah… that’s pretty fast….”
There was no time to laze around anymore. From the bedsheet I’d brought to the trail of wet footprints leading from the front door—there was way too much to clean up. First, I had to get dressed.
