Healing Bruises and a Sister's Awakening
The room, with its lights off, was shrouded in darkness. Sprawled face-down on the bed, Moonbyeol slept like the dead. Using the faint light spilling in from the hallway as a guide, I perched lightly on the edge of the bed and gently shook her shoulder.
"Moonbyeol. Wake up for a sec. Gotta put some ointment on before you crash again."
"......"
Even on normal days, Moonbyeol slept so deeply that you could carry her off without her noticing. In the end, I decided against waking her—just apply the ointment quietly and slip out. At least I didn't have to bother undressing her. She hadn't even managed underwear under the blanket, her pale ass right there in plain view.
I just gazed down at it silently. But it was hard to call it merely pale. The bruises blooming purple across her ass were in no way okay, even as a polite exaggeration. And it wasn't just bruising—her skin had split open in places, tiny beads of blood welling up.
I let out a long sigh. It wasn't enough to make me feel guilty, but it left a nagging unease in my chest.
"...Haa."
Putting aside stray thoughts, I opened the first-aid kit I'd brought. Ointment was essential if I didn't want scars. First, I wiped the beads of blood from her ass with some gauze. Then I smeared ointment thick on my finger and spread it generously over the bruised areas.
"Hngh!"
Moonbyeol's ass twitched as if in pain, a faint groan escaping her. Each quiver of those round cheeks sent little ripples across them. And yet she showed no sign of waking—must've been out cold.
I applied it meticulously, over and over. Staring at that plump ass and the smooth line of her thighs trailing down from it, I muttered under my breath. A lament thick with regret.
"Sigh. Why'd something like this have to be my little sister."
Finally, I stroked her ass one last time as I stood. The rubber-ball bounce under my palm stirred an urge to keep groping forever.
"If only you were the girl next door."
Then there'd be no heartache like this, and I'd have fucked her without a second thought. I murmured my regrets. Even "discipline" would've meant golf club swapped for my cock to set her straight.
I saw this second life of mine as half pure bonus fun. But blood ties were a scary thing. I couldn't bring myself to cross into anything beyond family first.
I slipped quietly out of the room. In the now-silent space, Moonbyeol—face buried in her pillow—had ears flushed bright red before I knew it.
"What the hell..."
Her chest tickled, her lower belly heating up. She reached back and brushed her ass lightly. Just a sting—nothing like the molten, melting heat when Taeyang had applied the ointment.
"More... touch me..."
Her murmur, heavy with longing, soon dissolved into the darkness.

The next dawn, I woke early as usual and stepped into the living room—only to pinch my cheek, wondering if I was still dreaming.
"......Huh?"
Nope. So who the hell was standing at that sink? No, the neat bob just brushing her shoulders and that classic Coke-bottle figure were pretty familiar. It was just the situation that didn't match at all.
Sensing my stare, Moonbyeol turned around. She was doing dishes, red rubber gloves on, plate in hand. She pouted.
"What."
"Just wondering what wind blew this in."
Moonbyeol peeled off the gloves casually.
"I'm not a kid anymore. Funny leaving all the housework to you, bro."
Sure, she handled basic cleaning and sorting recyclables, but compared to what I did, it was a drop in the bucket.
I stood there blankly for a while before suddenly chuckling and walking over.
"Moonbyeol."
"Yeah?"
I spread my arms wide and crushed her in a hug.
"Lemme hold you once."
"W-wait!"
Whether she squirmed or not, I squeezed her tight. Her face buried in my solid chest, Moonbyeol stomped her feet helplessly, unable to refuse. Her stray hands slowly crept upward. This much should be fine, right? Thinking that, she rested them on my back.
I'd never noticed before, but a brother's embrace could feel so vast and warm. Just a few years ago, we'd hugged like this all the time... A needless pang of regret made her nuzzle quietly against me.
"You've finally grown up."
"...What, doing dishes makes me mature?"
"Next thing you know, you'll be cooking too."
"...Not like I couldn't."
I grinned and kneaded her shoulders firmly.
"Forget cooking for now. Let's go on a bro-sis date after ages."
"D-date?! What kinda bullshit is that?!"
"Head straight home after school bell. I'll teach you grocery shopping from scratch. Even knowing how to shop is a relief. For real."
"Oh. That date."
Her brief excitement deflated, but still, going out just the two of us had been a while.
"We'll grab takeout too. Got after-school plans or what?"
"Nah."
Moonbyeol shook her head lightly. There was a class soccer match after school, but who cared. Striker spot was popular anyway; they'd manage.

Leaving Moonbyeol poking at her breakfast with an odd expression, I headed out first. High school starts earlier, naturally.
"She was doing all the dishes this morning. Guess a night did her good—says she can cook too. Planning to start with grocery shopping lessons. Was worried she'd live off delivery once independent, but this puts my mind at ease."
Hair tie in my mouth, I brushed Ahyeon's hair as she sat on my lap. Each pass from crown to back brought a faint shampoo scent with a soft rustle.
She could do it herself just fine, but Ahyeon always came to school, undid her perfect hair, and climbed on me to have it redone. Made me basically an expert on girls' hair.
Her face utterly relaxed, she giggled dopily.
"Hehe... feels so good..."
"Hey, chin up."
Skilled hands twisted her into twin tails and tied them. Finished with a flatiron, I planted a light kiss on her nape.
Mwah.
"So yeah, heading home early today."
"No way, that means two days without playing! You ghosted yesterday without a word—know how worried I was?"
"...Didn't I text?"
Ahyeon swung her legs on my lap, trying to act sulky heavy, but to me it was just cute whining.
"Texts ain't enough!! At least call!"
She spun around to face me, our lips inches apart. She growled.
"Grrr... yesterday you didn't even show..."
After a moment's thought, Ahyeon asked.
"Can't I tag along? We three together?"
"Greedy much. Then what if Moonbyeol crashes our alone time later?"
She shut up at that, pondering hard. Her face hardening fast—probably imagining something adorable.
"Tch, fine, I let it slide 'cause it's Moonbyeol's face, but till end of school, you're mine."
Ahyeon yanked my shirt collar while slyly grinding her hips to tease my cock. The sensation through my pants said it clear: no panties today.
"Not like usual?"
I chuckled; she laughed too and dipped her head, nipping my nape. No intent to hurt. When she pulled back, it glistened with her spit.
"That too. Wanna skip all classes and hit the rooftop?"
"First, gimme your self-scored midterm."
"Ugh... You didn't even look..."
Mid our silly banter, the class rep came right up to the back of the room.
"Ta... Taeyang?"
"Yeah?"
Meeting my eyes, her face flushed and she looked away. Wondered why, but thinking about my state, it clicked. Ahyeon yanking my collar had bared some chest, plus the hickey on my neck—plenty stimulating for a straight-laced class rep.
Unable to meet my gaze properly, she stared into space and stammered on.
"Teacher... wants you in the staff room... long time... anyway, that's it, I'm going!"
"Ah."
Makes sense—not like any other day, I'd skipped midterms without notice. I slipped a hand under Ahyeon's armpit to stand her up, then rose myself.
"Be right back."
"No! I'm coming too!"
"Sure, sure."
With Ahyeon linking arms, we headed to the staff room.
