Ugh, Uweeeek!!
It was hard.
Not for any other reason — it was the sight of myself, lifting my skirt right in front of Areum, hoisting my own hips up and spreading my legs wide open, that I could barely stand to endure.
And of all places, it had to be the Parents' House. The family was gathered right outside. I kept worrying my moans would leak through the walls.
"Hh, hhk…! Hup! Hhk!"
This was the bed where, as kids, we'd lain side by side and talked about everything under the sun.
"Hnn! Ha, haaang! Hhk!"
The place where we'd poured out our worries, or shared the kinds of secrets meant for just the two of us. But now, the only purpose this bed served had been reduced to sex.
"Ha, hnn… Squeeze it. Squeeze that fucking cunt tighter! Hup! Haah…"
The body of that Areum bitch — the one whispering such filthy things into my ear — started to tremble. I could feel the coarse hair of her mound grinding against my own. Front to back, side to side, she rubbed her lower half against me, and my clit was screaming.
"Hh! Hhaak! Haaang!"
"Hhk! More, more! Mooore!"
Areum's stifled cries ringing in my ears were the signal. At that signal, my lower belly began to swell.
Tzziiik— tzziiik—!
A hot, alien sensation hammered against my hypersensitive vaginal walls. Thud- thud-thud-thud- — an irregular pulsing sound, and inside me it ballooned even bigger.
"Haah, stop… i-it's… stooop…"
It felt more disgusting than the cock-juice she'd dumped into my belly. Especially since this load was trapped in a condom — it wouldn't soak into me, just sat there behind a thin rubber membrane, giving me nothing but a foreign, queasy pressure. And the tip of the cock, buried so deep it felt like it was lodged in my core, rose in a blunt, thick swell and kept tapping-tapping- against something inside me.
"Pull it out… already… th-this feels… hnn! Weird…"
Slap-! Slap-!
"Kyaaaaang!!"
"Shh. You trying to let the whole neighborhood know we're fucking?"
"Kyaaup! Huup! Haup!"
I'd thought it was over. That was a mistake. The orgasm had finished, so this godawful sex should have been finished too. But the cock hardening again, and Areum's hips starting to rock front to back, made it clear that what I'd taken for an ending had only been another beginning.
"I—I'm sorryyy… hah… hnn! I'm sorry, hhk! I'm so sorry…"
The pain had more or less vanished by now. Penetration wasn't that difficult anymore either — and that only made the swelling pleasure more terrifying. Of course, separate from all of that, the revulsion I felt toward the man's body straddling me was still very much intact. Even if that body was mine, and even if the body I currently occupied was Areum's, there was nothing I could do about this physiological rejection.
"Sorry? If you're sorry — hnn… then squeeze that cunt hole tighter… haah. Got it?"
Areum's body stacked on top of me pressed down hard. My large breasts were crushed flat, so tight I could barely breathe. I tried to shove her heavy frame off with my hands — but both wrists were caught and pinned above my head. Then my legs were hooked over her shoulders, leaving me in an even more humiliating position.
Slap—! Slap—!
"Hh, hhk! Hhk! I-it hurts… too deeep…"
It was a grotesque position. My hips were hoisted high, the backs of my knees draped over her shoulders. Areum's body bore down on me with a crushing, solid weight. Nothing had ever gone this deep before. My stomach churned; my lower belly was packed full of cock.
"Heh, hehhek, please… hhk! Stooop…!"
Pinned underneath, all I could manage — in a voice that sounded ready to cut out at any second — was begging her to stop. And even that was already half-incoherent.
"Hh! Haah! Just a little more, hnn… tighter, squeeze tighter… haah, I think I'm about to cum again… hhk!"
At Areum's words I clenched down below as fast as I could. I just wanted this over with, even a second sooner.
"Cum! Cum alreadyyy! Hhk, haaaaang!!"
Under the violent thrusts jabbing into my womb, something in my head finally snapped.
Fwoosh- fwoooosh—
At the same time, a wet sound burst from my cunt hole; my waist and ass started shuddering; the vaginal walls convulsed with lewd, rolling spasms.
"I, I came… haah, I… came first, so… st-stop… stooop…"
My eyes rolled back. It felt like I'd just sprinted a full marathon at top speed. My exhausted body had gone limp ages ago. But Areum's hips were still pumping, still driving that cock in and out of my cunt with wet, relentless thrusts.
Driving two cars was too much of a hassle, so we decided to take just one. All five of us piled into Uncle's car — Uncle behind the wheel, Auntie in the passenger seat, and me, Unnie, and Oppa lined up in the back.
But… Oppa — no. The Unnie sitting in the middle was acting a little strange.
Her face had gone deathly pale, like she was carsick. She'd sit there with her eyes shut as if she were dead, then jolt awake with a start every so often. She'd twitch and shudder like something hurt, sneak a quick glance at me, then close her eyes again.
"Unnie, would you like some water…?"
"Ah… no… I'm fine."
Unnie gave me a fake little smile that only lifted the corners of her mouth. But she did not look fine at all. I couldn't stop worrying about her.
"Unnie! Want to go to the bathroom together?"
"Ah, the bathroom…?"
We'd arrived at a rest stop, but somehow the three of us were still just sitting there in the back seat. At my question, Unnie's head turned sideways. She glanced at Oppa, reading his face for a cue.
"…What."
"N-nothing. I, the bathroom…"
"Go ahead, then."
Unnie tapped my shoulder — a signal to get out. I checked around us, then quickly opened the door and stepped out.
"Ah, Unnie. It's that way."
"Y-yeah. Shall we?"
I still didn't know why. But the person next to me — wearing Unnie's face — gave off such a strong feeling of being Oppa. It was a childish thought, and way too embarrassing to say out loud, but I could feel Oppa's warm soul so clearly it was almost unmistakable.
"The weather's so nice…"
"Yeah. Pretty decent for a day trip."
Something about Unnie's slightly awkward gait, the way she kept glancing around, lit a fierce sense of mission in me. When Oppa was Unnie, I had to take good care of him — nobody had told me to, but it was like payback for how Oppa had looked after me when I was little. Gratitude. Feelings like that just kept welling up.
"Unnie, your skirt rode up a little in the back — I'll fix it…?"
"N-no! I'll, I'll do it!"
I'd only reached out because the hem had curled up a bit, but Unnie jumped like she'd been shocked. She grabbed the edge of the skirt and yanked it down hard.
"U-Unnie! At that rate you'll, you'll pull it right off…"
"Y-yeah. It's fine, it's good now, right?"
Unnie turned her back to me with a look that asked if it was okay now. The skirt was covered in hand-wrinkles, but I met her eyes and nodded.
"Yes, it's fine now. Hehe…"
I took a big step forward and pressed in right beside her. We were about the same build, so standing next to each other we fit together perfectly.
"Ah, aah…"
"This way!"
I tugged on the arm I'd linked with hers and strode ahead. But Unnie couldn't quite keep up — the skirt seemed to be bothering her.
"S-slow down… m-my legs hurt a little…"
"Ah… I'm sorry. Then let me help you walk."
"N-no! I'm really fine… just a little slower…"
Unnie's face flushing red was so cute. Honestly, Unnie was pretty, but… her expression was so sharp she was a little scary… Still, knowing it was Oppa, cute was the first thing that came to mind.
Pressed right up against each other like that, we made our way to the restroom together. There weren't many people around, so it almost felt like Unnie and I had the whole place to ourselves. Even so, Unnie's face didn't look good — like just stepping inside made her uncomfortable.
"Unnie~ Can I go first? Will you wait?"
"Y-yeah, okay."
I felt a little bad leaving her out there, but I figured I'd just finish quickly and come right back out. I locked the stall, popped the button on my pants — and that was when I heard it.
"Uweeeek…"
A retching sound echoing through the restroom. Just a moment ago it had only been me and Oppa in here — and then Unnie's sickly face flashed through my mind. I refastened the button, threw the door open, and rushed out. Calling for her, I searched for a closed stall.
"Unnie? Unnie!"
"Ugh, uweeeek…"
The sound was coming from the far corner. Thankfully the door didn't seem locked.
Tap- tap- tap-
I ran toward the noise, my footsteps booming even louder off the restroom walls.
"Unnieee!"
I saw Unnie's back as she clung to the toilet. She startled at the sight of me and hurriedly flushed.
"…Are you okay? Want me to rub your back?"
"Hnn, nooo… I'm fine, I'm fine, so…"
"What do you mean fine? Huh? Should I go tell Uncle and Auntie?"
Unnie wouldn't show me her face. I was fretting, shifting from foot to foot — and then a scent I'd never smelled in my life brushed past my nose. I couldn't put into words what it was, but I was certain I'd never encountered anything like it before.
"Unnie, get up. Okay?"
"A-alright… I'm coming out, so just… give me a second?"
She seemed embarrassed about having thrown up. I quickly stepped aside.
"Hnn, haah…"
The sound of her catching her breath filled the restroom again, and only after the toilet flushed a second time did Unnie finally appear. She looked even more haggard than before, her face flushed bright red.
"Wh-what do we do? Should I go buy you some medicine?"
"Uhh, no, I'm really fine… And keep this a secret for me, okay?"
"No… why would you keep this a secret… If it's carsickness you should rest a bit, ah…"
And then it hit me again — the Unnie standing in front of me was actually Oppa. What if this was some kind of side effect? What if something was genuinely wrong? My thoughts, which had just started to settle, scattered all over again.
