75. Obsession
Afternoon 5 PM. In the changing room after my shift ended.
⋯I want to get out of here as soon as possible. Run to that place just a few minutes' walk away and be alone together.
"Good work~"
"Yep, good work."
Coworkers whose names I can barely remember. They're not bad people. If anything, they seem nicer than me.
But for some reason⋯ I just don't like them.
Maybe it's my paranoia, but it feels like they're sneaking glances at my little sister.
I can't remember if it was this one specifically, but one after another⋯
I wish people wouldn't look at someone else's little sister like that.
She's my little sister.
"Ah, G-Ga-eul-ssi, good work."
"⋯Yep. Good work."
"Uh⋯ do you have plans after work?"
"Pardon?"
"You just look so happy."
Is it showing on my face? Well⋯ yeah, I guess it would.
She's a woman so captivating that people keep stealing glances. No one could feel anything but a strange sense of superiority knowing she's yours.
⋯Even if she is my little sister.
But she's mine anyway.
"Yeah⋯ meeting my girlfriend."
"Oh right, you mentioned having one. Makes sense. You look jacked. Do you go to a gym around here?"
"Uh⋯ I did before enlistment. It's tricky now, so I work out at home. Got most of the stuff I need anyway."
"I see. ⋯Anyway, good work today. Have a great weekend, see you next week!"
"Yep."
A neatly dressed, tidy-looking guy vanished from the changing room with a swish. I quickly changed and headed to the usual back alley.
Today, no coffee. Instead, I clutched my phone and waited a bit.
Soon, the person I'd been waiting for approached. Her hands were empty too. Just a backpack slung over her shoulder.
"You're here. Shall we go?"
"Where to?"
"Somewhere to rest."
"⋯Ah, right."
We trudged out to the street. It's Friday evening, so there are more people than I expected.
I wonder if college will go back to in-person next semester. Or stay remote. Who knows.
Doesn't matter much anyway. The only thing that matters right now is the sister beside me.
I pulled out my phone again and made a call.
"Hello? Oh, Mom."
"What is it, son? Work over already?"
"Not yet. Just had a moment, so I called."
"Something up?"
"Might be late tonight. Grabbing dinner with the coworkers after shift."
"What about Gyeo-ul?"
"She's coming too, obviously."
"Okay? Got it. Don't stay out too late. Go easy on the drinks."
"No drinks, no drinks. I'll be home before 9."
"Alright. Drive safe. Bye~"
"Yep."
A little over three hours of leeway. Should be enough, right?
⋯Maybe not.
The urges might get satisfied, but the emotions just keep building. There might not even be a point where it's "enough."
Unless we're together forever, we'll always feel shortchanged in the time apart.
"⋯Oppa, how can you lie so boldly like that."
"Practice makes perfect."
"Wow, you're such a piece of trash, oppa."
"⋯What do you want me to do. Whose fault is this."
Trudge, trudge.
We keep walking. Good thing we're wearing masks. Faces hidden, so we don't look like siblings.
But honestly⋯ even if we showed our faces and wore name tags, once we pick up the keycard at the motel front desk, no one would think we're siblings.
"⋯."
"Gyeo-ul-ah."
"⋯W-what."
"Your ears are already red."
"⋯It's a little hot."
"Really?"
"Yeah."
Her cheeks were hidden by the mask, but probably the same color as her ears. I grabbed her warm, flushed earlobes with both hands.
So warm. As I cooled them with my palms, the elevator dinged open while we stared at each other.
My sister grabbed my wrist, pulled my hands away from her ears, and led me inside. I followed obediently until we reached our room door, where I suddenly stopped and stood there blankly.
She looked at me like what are you doing? So right there, I hugged her tight.
I buried my nose in her shoulder and sniffed noisily, a bit disgustingly.
"O-oppa, do it inside⋯!"
"No one's around anyway."
"Someone could pass by. What if we get caught, seriously⋯."
"It's a motel. They'll just think we're doing what comes naturally."
"What if it's someone we know? Why are you like this⋯."
"⋯So what."
"⋯Huh?"
"What if it is someone we know? As long as it's not a close friend."
Her usual snippiness is cute. When we're alone, she sneaks closer in that lewd way. I give in to the temptation and pounce, but then she gets embarrassed again. Teasing her more because it's cute makes her melt into a puddle, begging for kisses—that's lewd too.
"⋯Fine, let's go in first, oppa. ⋯We can't do it here."
"If my little sister wants to get that lewd, what choice do I have? I was just gonna hug and rest."
"⋯You gonna keep saying stuff like that, oppa?"
"Who was the one chatting with another guy?"
"What⋯ Am I yours or something?"
"You telling me you're not?"
"⋯I dunno about that."
Her jealousy over nothing is cute. She acts annoyed but her lips twitch up—that's lewd. I want to keep her lewd side to myself. Her non-lewd side? I want to show it off. Brag that she's my little sister, that she only likes me, that she's mine.
"You bit my ear hard enough to leave marks the second I said one word to another girl."
"That⋯ she was pretty, okay? Just in case."
"So what about you?"
"⋯I'm not into anyone but my real big bro."
⋯Always spouting contradictions, demanding a contradictory relationship, with that contradictory charm.
No need for foreplay or caressing anymore. One word was enough between us now.
Maybe not even that.
I swiped the keycard, opened the door, and pushed her inside bit by bit. We both naturally kicked off our shoes, closed the door, and made the space ours alone.
"⋯Gotta shower, so I'll undress you."
"⋯You sure you're undressing me just to shower?"
"Gotta shower whether we rest or whatever, right?"
"⋯Fine."
We peeled off each other's masks first, then shared light whole-body kisses.
The coat I bought her. The hoodie she stole from me. The skirt I bought. The stockings she wore when we did naughty things. The necklace I gave her.
We unwrapped them one by one.
A gray sports bra with a front zipper. Matching plain panties were all that remained, but knowing what lay beneath, we couldn't ignore it—no matter how suppressed.
How sweet it was inside.
"⋯I'll undress you, oppa."
"⋯You will?"
"You undressed me. ⋯My turn."
Now she started on me, reversing roles. The clothes she bought me, one by one. She took off my outer layer, unbuttoned my shirt in order.
Her crown came into view as she looked down at my clothes. I buried my nose there and sniffed, then spread my arms so she could toss the top to the floor.
Just pants left. She squatted, unbuckled my belt, and slowly unzipped my jeans. The outline of my cock struggling to poke out the side of my panties emerged.
I stepped out, kicking the pants to the floor. In our underwear, we kissed again, siblings once more.
We were both so aroused our panties were soiled.
"⋯Oppa, take mine off⋯ my underwear⋯."
"⋯You take mine off too."
Simple requests exchanged, then we devoured each other's mouths again, baring our desires.
I unzipped her bra, and her breasts sprang out. Breasts I never tired of seeing or touching. Too impatient to fully remove it, I left the bra dangling on her shoulders and kept enjoying them.
She tugged my panties down a bit and hugged me so my cock touched her navel, savoring my kisses. When I pressed down from above, she held her breath to take it, then we parted to gaze into each other's eyes. This time, she stood on tiptoes to match my height and kissed me.
My hands kneading her breasts naturally slid down, stripping off her remaining underwear. When we reached the breaking point, we stopped kissing and tossed the now-useless undies to the floor.
Nothing left but our naked bodies.
"⋯Let's shower."
"⋯Yeah."
I gazed at my little sister's nude form.
You gazed at your big brother's.
We both swallowed hard, then clung again, whispering in each other's ears.
Supporting hips and backs like a waltz, we matched movements, inching toward the shower.
I opened the door, stepped in first, and you traced my instep with your toes, following carefully. So we wouldn't slip. Leaning on me.
"⋯Turning on the water."
Into the shower stall, showerhead on. Cold. The unheated stream cooled our heated bodies.
But it was so cold we hugged tighter. Feeling heartbeats. Thump-thump.
The water warmed gradually, wet hair regaining its heat. Eyes squeezed shut, but it didn't matter. We didn't need sight anymore—we felt each other.
"Ha⋯ah⋯. ⋯Oppa. Body wash."
"⋯Ah, yeah."
Sister, reeling in her near-flying reason, pointed to the body wash behind me. I reached back, squirted a ton into my hand, then drenched her cleavage until it overflowed, tossing the bottle aside.
"⋯Oppa?"
"Turn around."
I gripped her shoulders, spun her half a turn to face the same way, shut off the shower, and rubbed my cock on her ass while scrubbing her front wildly.
Skin on skin didn't foam much, but the slick body wash let me clean every corner, breaths leaking out.
"Seriously⋯ pervert⋯."
"⋯I'm washing you."
"Ha⋯ah⋯. You finished, why aren't you stopping, oppaaa⋯."
"⋯Not foaming well."
"I'll wash you too⋯ so turn back⋯."
She spun back to face me, rubbing her slippery torso on my chest to clean me. She stroked her belly, then used the lather on my cock. Fingering my wet pubes foamed it up.
The sticky glans sensitivity. The softness of her wet breasts everywhere. That face looking up with dazed eyes and a soft smile.
Head about to explode, I turned the shower back on, overlapped our mouths, blocking breaths.
"Mmph⋯mm⋯."
Until all the excess body wash rinsed away. Eyes shut, pelted by water. Feeling each other up, cleaning thoroughly.
Even though it'd get dirty again soon.
"⋯Ha⋯ah. ⋯Oppa."
"⋯Wanna do it like this?"
"No. Gotta dry off first⋯."
"Can't hold back. Use your mouth."
"⋯Mouth?"
"You cleaned it. It's fresh."
"⋯."
A kiss to her hesitant self, and she knelt obediently, looking up at me.
Satisfaction surged up my spine. Knowing you're loved—pure bliss.
She gripped the cock she'd cleaned with her own hands and, unlike kissing, slowly took it into her mouth.
Still clumsy, but she kept showing me room to teach her.
"⋯Like last time. Don't just lick—suck this time."
"Mmph⋯yeah⋯."
A bit deeper than before. Awkward, but definitely sucking. Perfect servant pose.
Lewd sounds pouring out as she eagerly pleasured her big brother's cock and balls.
"⋯Mmph⋯hnn⋯slrp⋯ah⋯. ⋯Oppa."
"⋯What."
Not quite at the edge yet, but suddenly she spat it out.
Regret hit hard enough to scold her, but she swept wet hair back, looked up, and pleaded desperately with her big bro.
"Let's go out⋯ bed⋯. I can't hold back either⋯."
"⋯."
"Not mouth⋯ somewhere else⋯."
"⋯Where?"
"Make me yours right now, since I'm not yet⋯ where you can make me yours⋯ please."
I have to make her mine. As soon as possible.
No more time to even dry off.
