It Should've Been Just for Me
Park Eun-ji's expression looked amused. That didn't mean her current face was ridiculous, though.
"Ah, haaah…."
She glanced down at my glans pressing against her lower belly. She tried to act unfazed… and kept pretending to stay calm in front of me, but the flush spreading across her cheeks and her strangely quickening breaths gave her away.
"Move."
"……."
I spoke coldly without meaning to. I was a little surprised at myself for going this far, but it was probably because of Park Ah-young squirming behind me. Men never stop being childish creatures, no matter how old they get.
"Not moving? What are you planning to do standing there?"
It was a pointed question. At my words, it wasn't quite a sneer, but I couldn't stop the corner of my mouth from twitching upward either.
"…Stop it already."
"Stop?"
"Yeah."
Park Eun-ji gave a small nod. Her expression looked like she was barely holding something back.
I was used to that face of hers. It was the exact look she'd worn right before swinging her fist at me.
I felt my body tremble slightly. Once something gets carved into your body, it seems you can never really shake it off.
"…Don't wanna?"
Smaller ones always puff themselves up to look bigger. I knew I couldn't afford to be looked down on. So I bluffed too.
"Do I still have to listen to whatever you say?"
"……."
"You keep forgetting, don't you…."
I swallowed the rest of my words and parted my lips. Park Eun-ji's eyes followed them.
Fuck… Should I just say it all?
"Ah…."
If anyone saw this, they might think I was being petty and pathetic for threatening her like this. But this was my method. The only way I could win against Park Eun-ji.
"If you understand, move. No… get lost."
"……."
Park Eun-ji didn't budge. Her lips were pressed tight, her whole body rigid.
"Can't hear me?"
I could've backed off. If I gave in, that would've been the end of it. But why should I? I didn't need to back down anymore.
Press—
"Ung, ugh…."
My erect cock poked against Park Eun-ji. She flinched for a moment, then squeezed her eyes shut.
"What do you think you're doing with me right now."
My tone grew even colder. No—I made it colder.
Press— Press—
The thin scrap of a t-shirt might as well not have been there. I could feel the soft skin of her lower belly clearly.
"Ah, uh, uum…."
Behind me, Park Ah-young flinched as well.
Grip—
My clenched cock grew even harder. That hardness kept poking at Park Eun-ji.
"Hey… Kim Do-hyun."
Her voice was low. It wasn't eerie or frightening… but somehow damp, sticky.
"…Do you really have to do this even to my sister…?"
"What?"
"…I told you not to touch my fucking sister, you bastard…."
Her voice had shrunk, almost crawling.
At this distance, Park Ah-young couldn't possibly have missed hearing it. She trembled even harder.
"Ah, that's why I told you beforehand."
"……."
I leaned my head forward. With my neck lowered, our faces were almost touching.
"…I clearly told you your sister's fucking delicious."
"Y-you fucking… bastard…."
Park Eun-ji ground her teeth. The sound of them scraping together rang out briefly.
The startled Park Ah-young flinched again.
"…It should've been just me… just for me. Why, why even my sister… why my sister too!"
Park Eun-ji seemed to be misunderstanding something. She looked like she thought I was some filthy bastard who had forcibly raped Park Ah-young and blackmailed her the same way I had with her.
"Ahh…."
It wasn't entirely wrong, so I felt a twinge of guilt. But what mattered wasn't the process—it was the result. And right now Park Ah-young was dripping pussy juice just from looking at my cock, busy swallowing saliva through her hole, so this situation worked out fine for everyone involved.
"Looks like you didn't see it properly earlier…."
"Kyaa, kyaaah~"
Park Ah-young was pulled forward by her wrist. The girl who had been behind me now stood between Park Eun-ji and me.
"Take a proper look this time."
"Ah, uh, uh…? Ugh, ugh…♥!"
When I grabbed Park Ah-young's breasts, a lewd little nasal moan slipped out.
"Ung, Eun-ji's… watching, she's, she's watching… Ah, aah♥!"
I rolled her small, rice-grain nipples between my thumb and index finger. Park Ah-young shuddered as if getting goosebumps, then started rubbing her ass against my cock on her own.
"…What the hell are you two doing…."
Park Eun-ji's gaze turned cold. It wasn't just her eyes—her face was paling, turning icy.
"Ahng♥! I-it tickles too much…!"
Park Ah-young twisted her body. While squirming her waist, she subtly rubbed her ass crack against my cock.
"Ah… haa, hng! Ha, haaang…."
Eventually she stood on her tiptoes, even lifting her heels to adjust the height.
"Uum… Can I put it in?"
"R-right now…?"
Her voice sounded like she couldn't believe this was happening right in front of Park Eun-ji.
"It's not like it's the first time you're seeing it… Isn't it fine?"
"B-but… uh, even so… it feels a bit weird…."
She'd already been caught getting fucked like a dog by her own sister. Normally a person should feel ashamed. But humans are creatures that adapt… so the strong rejection from before was nowhere to be found.
"Don't you want to show it to Eun-ji?"
"…Sh-show what?"
"How your big sister gets fucked by me."
"Ah, ugh… Th-that! It's really… too embarrassing…."
The point was a bit off, but I didn't dislike Park Ah-young's current way of thinking. No—I liked it. I liked it so much I couldn't just stand still.
"Kyaa, kyaaht?!"
Among the two hands kneading her breasts, I moved only my left hand downward. My palm slid over smooth skin until it met soft, fluffy hair.
Rub— Rub— Rub—
She had just finished bathing. The place, freshly cleaned with water, felt a bit dry at first, but as my fingertips dug in, slick moisture soon came out to greet me.
Squelch—
"Hee, heeht"!
"…Already wet?"
"Ah, uh… Yeah… I've been, I've been like this the whole time…."
Park Ah-young's eyes grew moist as she tilted her head back. Her tongue peeked out between her lips and kept licking them, like she was swallowing saliva in front of something delicious.
"Should we go to the sofa?"
"…Ugh, yeah. Anywhere's fine… I wanna go. I wanna go…."
Park Ah-young whined like a child. Soon she leaned her back against me, entrusted her body completely, and went limp.
"Carry me?"
"Mmhm… I'm tired… I can't stand anymore…."
Park Ah-young convulsed with my finger halfway inside her pussy hole.
"Kyaaah~♥ Ah, haa… More, more… longer… thicker…."
But it seemed my finger wasn't enough to satisfy her.
"…What do you mean by longer and thicker?"
My gaze quietly turned forward. Park Eun-ji was watching with a complicated expression.
"Uung… Do-hyeoni's, co-cock…."
Park Ah-young, already heating up, had her brakes broken. She pushed her little sister's feelings far away and moved according to her instincts again.
And Park Eun-ji's gaze as she looked at her was unusual. That look at her own sister seemed mixed with various emotions. She alternated between staring at me and Park Ah-young with an unpleasant face.
"Follow me."
"U-ung!"
The words weren't meant only for Park Ah-young. Park Eun-ji, who had been listening right in front, also flinched and turned her body in the direction I was heading.
Step— Step— Step—
"Haa, ha… Hehe, haaang…♥"
Park Ah-young's laughter didn't stop. That laugh looked quite happy, but her excited expression was full of lust.
Thud—
"I'll stay still, so you do it yourself, noona."
"…Myself?"
"Yeah."
"Ah… I'll do it, I'll do it!"
Park Ah-young nodded repeatedly with a lively, lewd expression. She glanced back at Park Eun-ji and twitched the corner of her mouth slightly.
"…Then, can I, Do-hyun, get on top of you…?"
"Do whatever you want, noona."
"…Thanks. Then from on top, ugh, ugh…♥"
Park Ah-young quickly threw herself on top of me. She placed my thighs between her legs.
"…I can just put it in like this, right? Ah, or… should I suck it with my mouth? Which do you like better…? Ung?"
She tried to insert right away, then flinched and checked my expression with her butt. She seemed concerned about doing whatever she wanted, but I didn't dislike being led by this kind of proactive woman.
"Do whatever you really want, noona."
"…Then I'll put it in right away. I, really… can't hold back anymore…."
She glanced back again. I didn't know if she was provoking Park Eun-ji… or really being conscious of her.
Press— Press—
"Ah… Just touching like this feels too good… It's hot, and hard… Ah, aah♥!"
Her pussy hole, not fully opened, felt a bit tight. It was like trying to stuff a camel through the eye of a needle.
"Uung… Why, ah, won't it go in…."
The angle was a bit awkward too. Maybe because she was in a hurry.
"I'm not going anywhere… Take it slow."
"…I want to put it in quick… I'm gonna put it in…."
From under the squirming Park Ah-young, slick pussy juice was dripping out. And Park Eun-ji, who had suddenly become invisible, watched us with her mouth slightly open, dazed.
