From the First Moment I Saw Oppa, I Fell in Love at First Sight!
"Yeah, that happened. Now go fetch Soyeon quick. We'll rearm our spirits, and I'll fuck both of you properly right here."
As he said that, he added a warning not to put any silly ideas into that little brat Shin Da-hee's head.
Showing Shin Da-hee this blatant sex disguised as a massage with his women right now was his way of laying all their relationships bare from the start. It sure as hell didn't mean he was planning to lay a hand on the little one, who was now like a little sister to all three of them.
"Tch, fine."
Kim Gayeon hopped off the sunbed with a grudging nod, then dove into the pool with a splash. She swam quickly toward the two women watching from afar.
The three of them huddled together, whispering... Huh?
After a moment of secretive chatter, they all turned to look at him—me—at the same time, nodding in unison. But it wasn't Lee Soyeon coming over. It was Shin Da-hee, the little brat, slowly swimming toward me where I sat by the poolside sunbed.
She reached the ladder at the edge, grabbed it, and climbed out slowly.
Meanwhile, as Shin Da-hee made her way over, the other two—Lee Soyeon and Kim Gayeon—headed out through the opposite entrance, back into the hotel.
"...What the hell? Da-hee, what's up with your sisters all of a sudden?"
"Uh, yeah, Oppa. It's just..."
Shin Da-hee scurried over to my sunbed on quick little steps, then started fidgeting, biting her lip. I'd had a bad feeling ever since those three put their heads together, so I cautiously asked her to confirm my suspicions.
"Da-hee, what did Gayeon just say?"
"N-nothing! She just told me to call Soyeon-unnie for you. Th-that's all...!"
She twisted her shimmering silver hair around her finger, hesitating, then—as always—spread her legs naturally and plopped right down on my lap.
"Unnie said they're preparing a birthday party for my adult milestone. They went to your room first—not mine, but yours and the unnies' on the 100th floor—to get stuff ready."
"Oh... r-really? There's still plenty of time bef— Hmph?!"
Squeeze—! Squeeeze—!
...But this time, it wasn't just some cute coquettish wiggle on my lap. On top of that adorable little ass, she was subtly flexing the plump mound between her legs, grinding up and down. This little brat... what the fuck was she thinking right now?!
...No fucking way. Only a total impotent harem protagonist loser wouldn't get this blatant sex appeal. That bitch Kim Gayeon... what the hell did she say to the kid!?
Of course, I wasn't some neutered harem protagonist pussy. I clocked Shin Da-hee's obvious sexual invitation right away.
Actually, I'd sensed it a few times over the past three days, but it hadn't been this aggressive before. And if she was seeing me as a replacement big bro for her real one, Cheol-su... it was still within acceptable skinship territory, so I'd let it slide without a word.
But this? This shit she was doing right on top of me...
"Y-you little tease! Alright, get off for now. With our pretty Da-hee in that matching bikini looking all cute like this... heh, it's making things a bit tough for Oppa."
Shin Da-hee was decked out top and bottom in a pure white bikini that matched the glossy sheen of her silver hair. The top was super bold, exposing her entire back, and the bottoms were barely palm-sized. I'd been shocked when I first saw it. The front was one thing, but the back was straight-up a thong, leaving most of her ass bare.
I'd thought it was a bit too provocative for a girl who just turned legal, but once we started playing in the water—me carrying her, hugging her—it became the new normal...
Now here she was on my lap, her face flushed like a ripe persimmon, earnestly pressing that firm, jiggly ass and pussy against me right in my face. And after I'd just finished one quick womb massage session with Kim Gayeon... my cock was starting to stir under my swim trunks.
No, I mean, I'm a guy, so it's not like I can help it... damn.
Getting hard was getting hard. But no matter how much this little one teased, my heart wouldn't waver. I couldn't give her that...
"Mmph! Mmmph?!"
"Smack! Chuup...! Hehe. Thanks, Oppa. For saying I'm pretty. Muah! Muah...!"
...It happened in the literal blink of an eye. This cute little thing I'd treated like a real little sister forced herself against my hands trying to set her down beside me and stole my lips.
I just stared blankly down at her impish, giggling little devil face after that insane stunt.
"Wh-what the hell are you doing, you rascal?! That's not funny anymore!"
"I-it's not a joke...! You know it too, Oppa. I'm an adult now, so I can legally do all this stuff with you... everything...!"
At my slightly raised voice, the little devil curled up like a squirrel but didn't climb off my lap. Instead, she scooted deeper in, aiming that tiny, adorable ass wrapped in the thinnest fabric—and her plump little mound—right at my cock like it was gonna burst through my trunks.
Squeeee—!
"Hyaaang?! O-Oppa...!"
"No way. This horny little brat is for real...?!"
If I'd shut it down hard before she even sat, maybe. But now? Ruining the mood? And this freshly legal kid summoning the courage for this... what the hell was going through her head?
With a complicated sigh, I gave up trying to talk her out of it and seriously embraced the body of Shin Da-hee, who'd mustered her own courage.
"Haa... Da-hee, you really didn't trust Oppa that much? Did you think I'd treat you carelessly?"
"N-no, that's not it! I've always liked you, Oppa...! I met you way before the unnies, and I liked you first...!"
"...Huh? What?"
Her sudden, totally unexpected confession made my hard-won composure bail on me again. Wait, what? Why me? It wasn't just because she missed Cheol-su and saw me as a familiar face in this shit world...?
"W-well... Uh, ahem!"
"Kyaa! O-Oppa?!"
Squeeze—! Squeeeze—!
Even in my genuine fluster—the first real panic in ages—my now fully raging erection wouldn't quit. My cock, skyrocketing straight up at 90 degrees, mercilessly poked and prodded the virgin pussy of this teasing little brat who'd thrown me into chaos.
And with every twist and throb, the faint blush on her embraced erotic little face deepened like a gradient.
"Eek! Hnng...! O-Oppa...! S-so, yeah! I wanna be your woman like the unnies. That's okay, right...? I-I can tell you like me a lot from this...?"
As she said it, her doe eyes looked up at me pitifully. Her tiny hands wrapped tight around my neck, face nuzzling in. Even mid-thought, sorting out my feelings, I couldn't bring myself to push her away.
...So I gently patted the back of her trembling slender body. I closed my eyes, stayed silent in contemplation for a long beat, then looked down straight into hers—eye contact locked.
"Yeah... sure. Oppa likes our Da-hee a whole lot too."
"...Huh? R-really?!"
At my positive response after that long deliberation, Shin Da-hee widened her eyes and stared right at my face.
"Yeah. Really."
"Sniff, sob! Oppa...!"
Tears finally burst from the little one. I cupped her soft cheeks lightly with both hands, pulling her lips close.
"Muah, muah... Sigh, even for Cheol-su's sake, I really, really never planned to touch you... What is this? The second you turn legal... damn this erotic little brat!"
"N-no! Sniff... Y-you're the bad one, Oppa. The past three days, you've only been with the unnies every day... I-I flirted so much too!"
"...Ahem. Up till yesterday, our Da-hee was still a minor. And like I said, Cheol-su was on my mind."
"Ah, th-that...! Don't worry about it, Oppa!"
Maybe from the joy of me accepting her, she stopped sniffling quick and bounced back to her usual energy, grinning wide as she went on.
"Why do you think our Oppa—Cheol-su-oppa—introduced us back then? That first time we three drank together...!"
"...What? No way..."
I stared holes into her face, half-disbelieving. The grinning erotic brat confirmed it quick enough.
"Hehe. He said he'd love it if you and I got together. He called you a real friend, right? He said he'd feel relieved if we dated...!"
"...That dumbass really! Why didn't he fucking tell me?!"
I was so flabbergasted I looked up at the sky, grumbling. Then—
Squeeze—! Squeeeze—!
Shin Da-hee pressed even tighter, chests mashed together with zero space left. Her face turned into one of pure, utter bliss.
"Hehe...! But I didn't fall for you just because of that later story. I've been in love with you since the first moment I saw you!"
