The Sister Being Pinched, and the Younger Sister Watching
Yang Dami stopped short of leaving the house and turned right back around. She strode over to me and Yang Dahee, glaring daggers, and blurted out,
"Hah, why is it so hot in here!?"
And then, just like that, she pulled her top off.
My little sister, baring her chest right in front of her older sister and me. I could only stand there, jaw hanging open at the sheer audacity of it.
What is she doing? Why is she joining in too?
I snuck a glance to the side. Yang Dahee's enormous breasts were on full display.
So Sis doesn't care at all, huh.
Even with her little sister stripping down beside her, she just kept rotating her shoulder like always, acting like this was nothing more than another ordinary undressing session.
Is Yang Dami copying Dahee, of all things?
Her obsession meter had definitely ticked up. She even kept staring fixedly at my hand.
I looked back and forth between the two of them.
"…"
My sister, sitting and waiting. My little sister, standing off to the side. I slid my hand out and rested it on Dahee's shoulder.
"Mmmh…"
Yang Dahee let out a soft moan.
Meanwhile, from beside us came a sharp gust of movement.
"Hmph."
Yang Dami had whipped her head away.
She stalked right past me and headed toward the back.
"Honestly."
She grumbled as she slumped against the wall.
Apparently she wasn't happy that only our sister was getting rubbed down. She could've just said so out loud, but no — all she did was pout.
Leaving my sulking little sister behind me, I kept working on Yang Dahee's shoulders as I spoke.
"Sis, your shoulders are really knotted up."
"Are they? Hngh, mmh…"
Yang Dahee hunched her shoulders tight, but she didn't pull away. She just kept her eyes on the monitor, and I used the opening to sneak a peek behind us.
Tap-tap-tap.
Yang Dami, glued to her phone, completely oblivious that I was watching. From this angle, her chest was on full display.
She'd never know I could see.
Heheh.
Swallowing a laugh, I stole glances at my little sister.
D-dumbass…!
Yang Dami bit her lip where no one could see. She held her breath and stared desperately at her phone screen.
Yang Dajun, are you insane!?
His gaze kept flicking over to her, and her ears were burning hot because of it. Her own brother, massaging their sister while sneaking looks back at her…
Yang Dami's breasts felt restless, achy, tingly.
"Hah…"
A soft moan slipped out now and then — she couldn't even tell whose it belonged to anymore. Her heart was pounding so hard it felt like it might burst right out of her chest.
It beat so violently that even her nipples throbbed.
Yang Dami's nose stung, that pre-tears prickle creeping up on her.
D-dumbass… I told you to stop looking…
It had been an impulsive thing. Yang Dajun kept fawning all over their sister, and it pissed her off, so she'd canceled her plans. She'd bared her chest right in front of the two of them.
"Hah, why is it so hot in here!?"
She'd shown her brother her breasts. The weight of his gaze pouring over her had made her head swim.
"Hmph."
She'd stalked off with a creak of her joints and plopped down, grumbling for no good reason.
"H-honestly."
She was talking to herself. Breasts weren't supposed to be a big sexual deal, but somehow it was embarrassing anyway. And so Yang Dami just hammered away at her phone.
The screen was blank.
Yang Dajun was looking at her.
…Unbelievable?
He should've just kept doting on their sister like always. Instead he kept glancing her way.
Yang Dajun, are you staring at me right now?
He apparently thought he wasn't getting caught.
Yang Dami didn't cover her chest. She didn't move away, either. She was testing her idiot brother.
Honestly, how long is he going to look? S-so freaking ridiculous.
Yeah, he really was a dumbass. Without even realizing it, he was a total horndog for women.
In Yang Dami's mind, that was the only explanation. It was the only way it made sense.
Dumbass. It can't be because I'm his little sister that he's staring. He's just a pervert for girls, that's all.
Her brother, who clung to their sister every single day.
Yang Dami snuck a sidelong glance at the two of them. She could see Yang Dajun kneading away.
"Ahhng…"
Their sister was wincing in pain.
"S-stop it."
She hunched her shoulders and tried to dodge his hands.
"Sis, hold still."
"No, not there. Hyaagh…"
It must have hurt badly, because her voice was trembling outright.
And Yang Dajun, clueless as ever, just kept kneading away.
That idiot, how can he be so oblivious!?
Yang Dami finally bit down on her lip. She decided their sister was just too kind for her own good, enduring it out of politeness.
She was still debating whether to step in when —
"Sis."
"Mmh… what?"
"Working hard must be rough on you."
Yang Dajun hugged their sister from behind, wrapping his arms around her.
A honeyed moan burst out of her.
"Hah, haahng…"
Yang Dahee struggled to keep talking.
"Don't worry about me… nngh…"
Her voice had gone completely soaked and heavy.
The distance between the two of them was unnervingly close, but the back view didn't tell the whole story. Yang Dami lifted her hips slightly and craned her neck to see —
Huh?
Her eyes went round as saucers.
Yang Dajun had slipped his arms inside their sister's. His hands were wedged into her armpits, and it looked very much like he was rubbing something else entirely.
Yang Dami shrieked at the top of her lungs.
"Hey — Yang Dajun!"
Yang Dami's shout startled me and I looked back.
"Uh — what?"
"What do you think you're doing! Unnie's in pain!"
My little sister, glaring at me like she was about to charge over any second. I blinked and asked Yang Dahee myself.
"Sis, did that hurt?"
"No?"
She shook her head vigorously, but her face was bright red. Yang Dahee glanced at me with trembling, shivering eyes, then looked toward the back too — where Yang Dami still wore a deeply suspicious expression.
"Unnie, then what was that moaning about?"
"Ah…"
She hesitated to answer.
Because I still had her nipple pinched between my fingers.
Dahee, you need to answer her.
I let go of my sister's nipple and gave her breast a light pat instead.
"Ah…"
"Answer her, Unnie."
"B-because it felt good."
"You moan like that because it felt good?"
"Yeah… why don't you ask him to rub yours too. Heheh."
And there it was — my sister inviting her little sister to a nipple massage.
Both of them probably thought I was just some naive boy. And technically, sure, this wasn't just a shoulder rub — but it also wasn't really incest.
Being a man meant no one suspected a thing. A beauty was trusting me enough to offer up her chest. I found that so delightful that I set my hands moving again.
"Ahhng…!"
Yang Dahee moaned out loud once more. She didn't dodge my touch — quite the opposite. She arched her back slightly to give me more room to work, and thanks to that, I got to knead her huge breasts to my heart's content.
"Feels good, Sis?"
"Nngh…"
"Come on, answer me."
"I-it feels good. Hyaahng…!"
Every time I kneaded her, Yang Dahee buckled forward — so I'd grab her chest and pull her back upright.
"Sis, sit up straight."
"Mmm, okay. Ah — aahhnng…!"
I tilted my head a little and looked her body over. My arm was sticking out from under her armpit, and my skin glistened faintly with her sweat. Her whole body was giving off the scent of a woman in heat.
Sis, you're way too good to me. Not that I'm complaining. But you'd better never, ever allow this with any other man.
Even family or not, I hated the idea of her getting tangled up with someone else. I wanted her to stay my sister and no one else's.
Before I knew it, I was pinching the stiff, swollen nipple between my fingers.
Yang Dahee shrieked.
"Hyaaah — aahhhnng…!"
And then I heard a voice from behind me.
"Nnnh…"
Yang Dami was whimpering.
Dami, that bothered, huh?
She'd been quiet until just a moment ago. The instant Yang Dahee said it felt good, she'd buried her face against the wall again.
Then a sound started drifting over from somewhere behind us.
"Mmmh…"
A voice that grew steadily louder the more I worked on Yang Dahee. I didn't even need to turn around to picture her face.
She wants to chew me out but she's holding it in, right?
She had cooled down quite a bit — after I'd smacked her cheek. Or was that after I'd patted her head? I couldn't quite remember, but there was one thing I knew for certain.
I absolutely could not look back right now.
Meeting her eyes would set Yang Dami off. She was already simmering alone back there; if she saw me watching, she'd boil over and come charging out.
Do not look back. Ever.
I swallowed hard and locked my gaze straight ahead.
Strands of Yang Dahee's tied-back hair had escaped and stuck to her neck. The sweat trickling down her nape — that was my big sis, all right, and it was obscenely erotic.
"Nnh…"
A moan spilled out. Her legs curled inward. The faint metallic taste of blood bloomed on her tongue — she'd bitten her lip.
"Mmmh…"
Up front, Yang Dajun was kneading their sister.
Yang Dami's sunken-in nipple throbbed, burning hot.
"Mmnhh…"
It was growing, little by little. Every time she touched it, it strained up toward her fingers.
While Yang Dajun was distracted by their sister, Yang Dami toyed with her own nipple.
D-dumbass… just try turning around.
She scraped it lightly with her fingernail. She trapped it between two fingers and pinched, twisting it left and right as she glared daggers at Yang Dajun.
"Haahng…"
A moan burst out. She clamped her hand over her mouth, but another one escaped anyway.
"Hyaahnng…"
That one was her sister's.
Yang Dahee, sighing out those honeyed voices while receiving her massage — and Yang Dami let her own sounds ride along with them.
Nnh… just listen to her…
She held her breath, then released it right on cue. The more she did, the harder her heart pounded. Her breathing had gone ragged, and her thoughts slowed to a crawl. Yang Dami's ears felt waterlogged, numb and buzzing.
"Sis, sit up straight."
"Mmm, okay. Ah — aahhnng…!"
The two of them, huddled close, whispering words meant only for each other. Closer than they ever normally were.
Yang Dami bowed her head, but her nose prickled hot.
Honestly, how long is this going to go on?
She should have jumped in ages ago. Should have screamed at Yang Dajun like always, torn him a new one, put him in his place.
But she couldn't.
Damn it…
Her cheeks burned hot for no reason at all, and the rims of her eyes reddened. The top of her head felt empty. She ached for the memory of a hand pressing down there — a gentle pat, pat against her hair.
"Nnh…"
Eyes rimmed red, Yang Dami brought her hands up without even realizing it. One hand on her head. The other between her legs.
She was stroking herself.
Dumbass, you absolute dumbass…
She was already soaked, slick and dripping. She nibbled at her lip, leaving little stinging bites everywhere her fingers wandered. Her breasts tingled as hotly as her flushed cheeks.
"Hah…"
Timidly, she let her moans sync up with her sister's. Yang Dajun wouldn't notice anyway — he'd never bother turning around.
That was how it should have been.
"Dami?"
Someone called her name.
