Saengyeonrye Looms Amid Beachside Ecstasy
I had to do the saengyeonrye, but smack— whoosh—.
A deserted beach with hardly a soul in sight.

On the quiet sands of a weekday afternoon, fresh, bright voices began to echo for the first time in a while.
"There's seriously no one here!"
"No way. Feels like we rented out the whole beach."
"This is perfect. No crowds at all."
It was a group of three women.
Having shaken off the stuffiness of the city, they kicked off their shoes and stomped barefoot across the sand, letting out cheers of delight.
They spent a good while snapping photos in the cool sea breeze and splashing in the waves.
"Gotta hit the bathroom. Think I drank too many sodas."
The bobbed-hair woman clutched her stomach and peeled away from the group.
She headed toward the public restrooms—a prefab structure—behind the beach.
"Huh…?"
Her steps came to an abrupt halt at the edge of the beach.
From there, amid the crash of waves, a faint, eerie noise seeped through.
—Haa… ugh…
It was unmistakably a human voice.
A precarious sound, like someone crushed under something, barely gasping it out.
Her face hardened at the choking gasps.
What's that? Someone hurt? Washed up after drowning?
Maybe someone shipwrecked in the rocks.
If they needed help, she had to call 119 right away.
She hurried toward the secluded corner where the rocks jutted out.
Her feet sank into the soft sand.
But as she drew closer to the source, her pace slowed.
Because the sound hitting her eardrums was nothing like the crisis she'd imagined—it burrowed into her ears with a completely different vibe.
—Haaang…! Ah, ah! Do, Dojin aa…! Hngh…!—Slurp, smack…
Her steps stopped dead right behind the cluster of rocks.
Not a cry for rescue in agony… but the slick friction of flesh slamming flesh.
And a woman's sweet, fervent moans steeped in savage pleasure.
Gulp.
She swallowed dryly without thinking.
Despite her rational mind screaming to turn and run, curiosity glued her feet in place.
In the end, she cautiously peeked through a gap in the massive boulder, holding her breath.
"…!!!"
The moment she glimpsed the scene beyond the rocks.
She nearly yelped "Heuk!" but clamped her hand over her mouth just in time.
It was broad daylight.
In a rocky nook on the beach.
And there… two bikini-clad beauties and a ripped guy with his swim trunks halfway down were fucking.
"Cr, crazy…."
Her legs trembled like aspen leaves.
Not just because they were doing it outdoors.
It was their act itself—way beyond what her common sense could handle, delivering pure shock.
The man gripped the hips of the bobbed-hair woman lying on the ground and pounded his cock into her mercilessly.
Screams tore from her throat, on the verge of blackout.
But what seized her gaze most was what happened every time the man's thrust buried deep.
Squelch—! Squelch—!
Each time he slammed to the hilt.
Her lower belly bulged outward with a little pop, pop.
Wh-what the hell…? How huge is he for her stomach to bulge like that…?
A sight straight out of hentai.
Her face flushed crimson in an instant. Her breathing quickened.
Even though it wasn't her, her lower belly tingled, and wetness seeped between her thighs.
She had to run… but even as she thought it, she stared blankly.
***
"Haat…! Ugh, hngh…!"
"Slurp, smack… haa…."
The salty sea air mingled with thick musk, heavy in the rocky crevice.
I was in missionary with Eunseo, and her lower belly bulging every time I thrust my cock in was just… insane.
And even during sex, Eunha beside me had her arms around my neck, kissing me—it was driving me wild.
Out in the open air, with the waves masking our wet slaps, my reason had evaporated long ago.
Squelch—! Splash—!
"Aang! Do, Dojin aa…! Dr-driving me crazy… haaang…!"
Every time I gripped her hips and slammed in, Eunseo rolled her eyes back and thrashed.
"Haa…."
I pulled off her lips for a breath, exhaling roughly.
Eunha, licking her saliva-slick lips as she gazed at me, glanced down at the panting Eunseo below.
"Haa, haa… dar, darling… hn, look at this…."
Eunseo murmured in a pleasure-drenched voice, pointing to her belly with a finger.
Every time my cock speared her deepest depths.
Her toned lower abs bulged convexly along my shape, writhing.

"My belly, haat… look how it bulges… feels like your cock's gonna pierce right through, aa…♡"
Watching from inches away, Eunha gulped dryly too.
"Hngh…."
Eunha twisted her legs together, her trembling hand unconsciously cradling her own lower belly.
Probably imagining herself like that.
"Do, Dojin aa… I, hng… I'm, getting close…!"
As my hips accelerated toward the limit.
Eunseo teared up and gasped.
"I'm gonna cum… haaang…! To-together… darling… fill me up, so much…!"
I couldn't hold back anymore.
I unleashed everything deep inside Eunseo.
Spurt! Sploosh! Squirt—!
"Aaaaang────!!!"
Eunseo's back arched like it might snap as she climaxed.
Her inner spasms milked every last drop from me.
"Haa… haa…."
After the long, intense release, Eunseo lay sprawled with eyes rolled up, tongue lolling, drooling like a mess.
I panted, pulling my cock out.
Pop… With the sound, frothy white cum mixed with her juices gushed from her entrance.
Of course, I couldn't stop at just Eunseo. I snatched the wrist of Eunha, who was twisting her legs beside me, panting.
"Ah…!"
I spun her body around.
Hands braced on the cold rock wall, ass thrust back toward me.
"Haa… Do, Dojin aa… me, me too…."
Eunha twisted her head back, gazing at me pitifully.
I nudged her bikini bottom aside and rubbed a finger along her slit.
Squelch—.
The moment my finger touched, clear sticky nectar soaked my hand.
"Already this wet. No need for foreplay, huh?"
"D-don't say that… it's embarrassing, hn…!"
Before she finished.
I rammed my still-throbbing cock to the hilt into her dripping entrance.
Squelch—!
"Aaaang—!!! Ahh! De-deep, so deep… Dojin, too deep…!"
Eunha's spine bowed like it might break from the ruthless thrust.
Slap! Splash! Sploosh!
I clamped her pale hips with both hands and drove my waist upward.
"Haang! Ah! Dojin, Dojin aa…! Ng, good, so good…!"
Her walls clenched madly around me like they'd been perfectly molded to my shape, gushing pleasure nectar with every pound.
And so, we started fucking again.
About 30 minutes later.
"Haa… haa… ngh…."
Eunha and Eunseo.
Both lay slumped side by side on the rocks.
Eyes unfocused on the sky, mouths agape, heaving ragged breaths.
White cum I'd pumped into them oozed stickily from their inner thighs and spread pussies, dripping onto the sand.
"Ugh…."
Twisting my waist sent sharp aches screaming through every vertebra.
…Haa.
Catching my breath, I stared blankly at the two Eunhas sprawled on the rocks.
Reason returning, a realistic dread slowly rose in the corner of my mind.
I realized I needed to get serious… about preparing.
You know, like actually meeting Eunha's parents.
….
Sweat beading as I looked at Eunha and Eunseo.
…How the hell do I explain this?
Eunha's parents would find out about Eunseo's existence someday.
I couldn't even imagine the fallout.
For real.
