a/n : yeah. blame seonghwa. this was supposed to be soft. it’s not. vacation au, fast burn, strangers to something
You’ve seen him every day since you arrived.
Always up in that impossibly tall lifeguard chair, perched like a statue carved out of heat and sun.
His skin is golden — that kind of deep, effortless tan that only happens when you live in the sun.
His hair’s a little too long, curling behind his ears, damp at the ends from pool water or sweat.
Yeah. You’ve definitely looked.
Hard, defined, glistening under the sun — his red swim shorts hanging low on his hips, drawstring untied just enough to make you wonder if he even cares.
He’s lean but strong, the kind of strength that comes from swimming laps and hauling wet bodies out of pools.
A whistle dangles from his neck, brushing his chest when he moves.
His sunglasses hide most of his expression, but you know he’s watching you.
You noticed him before you even made it to your lounge chair the first day. You didn’t mean to. But then again, he didn’t give you much choice.
And you never even got his name — not really. Just “Hwa,” stitched in bold black thread across the hip of his uniform shorts.
He watches you. Every day.
When you stretch out in your chair.
When you slide into the pool like you don’t know what you’re doing — like you don’t know he’s got a perfect view of the way your hips move beneath the water.
You haven’t spoken. Not once.
But that was part of the game.
You stretch out on your towel under the hot sun, your skin warm and glistening with sunscreen. Seonghwa’s chair is in your peripheral vision, like always, and you know he’s there — because you can feel him.
You shift a little. Cross your legs. Sip slowly through the straw. And when you lean forward to grab your sunglasses, they accidentally slip from your fingers.
Right near the base of his stand.
You pretend not to notice at first. Just long enough to get his attention. Long enough to know he’s looking.
You wait a second. Then two.
Then you rise. Slow. Deliberate.
Barefoot, hips swaying, you walk over in your tiniest bikini — the black one, the one that makes everything look like an invitation.
You crouch to pick them up, taking your time, pretending like you’re alone.
You crouch down to grab them.
“Those yours?” a voice rasps from above, smooth like smoke and summer heat.
You look up — and there he is. “Hwa”.
Close enough now that you can see the flecks of gold in his eyes behind those dark lenses.
He’s leaned down, one arm draped across his knee, the other lazily holding his whistle.
“Didn’t mean to distract you,” you say, voice low, sweet.
He hums like he doesn’t believe you for a second. “Sure you didn’t.”
You rise slowly. His eyes follow every inch of you.
“Is this an invitation, or do you just like bending over in front of me?”
You straighten, turning just enough to glance at him over your shoulder. His sunglasses are still on, but you can feel his gaze—steady, low, not even pretending to be polite.
“You saying you didn’t like the view?” you ask, voice teasingly sweet.
He shifts in his lifeguard chair, forearms flexing as he rests them on his knees. “I didn’t say that.”
He hops down from the stand.
It’s instinct, maybe, or something deeper, but your breath catches the moment he’s level with you.
He’s taller up close, broader — all sun-bronzed skin and a slight sheen of sweat from the heat.
His whistle drops against his chest when he steps into your space.
“You want me? Just say it,” he murmurs.
Your heart stutters. “What if I don’t want you?.”
His jaw ticks. Like he’s trying not to do something reckless.
Then, with a low, teasing smile, he says,
“Oh, come on. You’ve been watching me all week. You think I didn’t notice?”
You lean in just a little closer, voice low and sultry. “Mmm… maybe I’m just waiting to see if you’re worth it.”
Then he jerks his head toward the pool’s changing room.
“In there. Three minutes,” he says, voice tight.
He turns and walks away — back to his stand.
You’re left standing there, sunglasses dangling from your fingers, mouth dry and pulse roaring in your ears.
You wait, and then glance at your phone — the three minutes are up.
With a slow, deliberate pace, you head toward the changing rooms, heels clicking softly on the pavement.
The sun’s warmth feels different now — heavy, loaded with anticipation.
Inside the cool, tiled room, you lean against the counter, arms crossed, your heart ticking faster.
You start to wonder… is he really going to come in? Or was this just a game to him?
Your breath catches when the door creaks open. You turn sharply—there he is, stepping in with that confident, unreadable look.
A slow smirk spreads across his face. “Waiting for me?”
You arch an eyebrow, teasing, “You do this with every girl who catches your eye?”
He steps closer, eyes dark and intense. “Mmm, only the ones I want to keep.”
Your pulse hammers as he closes the distance, the heat between you suddenly palpable. “Lucky me.”
He brushes a stray lock of hair behind your ear, voice low and teasing. “You have no idea what I’ve been planning.”
You bite your lip, eyes sparkling with challenge.
“Then maybe you should show me.”
He closes the gap, his breath warm against your skin
His hand trails slowly down your arm, fingers brushing lightly, sending shivers through you.
His eyes lock onto yours—dark, hungry, and unapologetically intense.
“You’ve been tempting me,” he murmurs, voice husky.
“All day, you’ve been right here, but now…” He leans in, lips just grazing your earlobe, “Now you’re mine to play with.”
You shiver, a delicious mix of nerves and excitement flooding your body. Your fingers twitch, desperate to reach him, but he pulls back just enough to keep you wanting.
Instinctively, your hand finds its way to his crotch, sliding up until your palm presses firmly against the hard planes of his abs.
The heat of his skin seeps into your fingertips, grounding you in the moment.
His breath hitches, eyes flickering down to your hands and back up, dark and hungry.
“You feeling me?” he teases, voice low and playful.
You nod, lips curving into a slow, teasing smile. “Yeah. I’m feeling you.”
His hands tighten on your hips, pulling you even closer. “Good,” he murmurs. “Because I’m just getting started.”
His lips find yours, soft and slow at first, teasing, exploring.
Your hands press against his chest, feeling the steady beat of his heart beneath your palms.
The world narrows to just the two of you — heat, breath, the taste of him on your lips.
Between kisses, you pull back just enough to whisper,
“You gonna ghost me after this?”
He smirks against your mouth, voice low and mischievous. “Maybe…”
The words catch you off guard for a second, but you shake it off with a smile. You’re here now, and that’s what matters.
Leaning back in, you thread your fingers through his hair, pulling him closer. “Well, I’m not going anywhere.”
His hands slide under your shirt, warm and sure.
“Good. Because I’m about to make sure you remember me.”
His kiss deepens, more urgent now, hands exploring, pulling you tighter.
Every brush of his lips, every stroke of his fingers sends sparks trailing down your spine.
You melt into him, losing yourself in the moment — and loving every second.
His lips roam from your mouth down to your neck, planting soft, possessive kisses that make your breath hitch.
You arch into him, feeling the heat build, every nerve alive with anticipation.
“You look even better up close,” he murmurs against your jaw, voice thick with desire.
You respond by slipping your hands around his neck, pulling him closer, needing more—more warmth, more contact, more of him.
He presses you back against the cool marble counter, a low groan vibrating from his chest as his body melds against yours.
His hands roam lower, cupping your hips firmly as he slides his mouth back to yours, fierce and demanding.
He pulls away just enough to look into your eyes, voice a whisper that sends shivers down your spine. “Tell me what you want.”
You don’t hesitate. “You.”
He smiles against your skin, and then says, “Good. Because I’m not stopping until you’re begging.”
You gasp when his fingers slip beneath your waistband, teasing the bare skin of your hip. “Hwa…” you breathe, voice trembling.
“Shh,” he murmurs, pressing his forehead to yours. “I wanna hear you say please.”
Your arms clutch his neck, pulling him closer. “Please.”
His grin is wicked. “That’s my girl.”
And then he dives back in — hands, lips, every touch sending waves of heat that ripple through your body.
Seonghwa’s eyes never leave yours as he carefully hooks his fingers into the side of your bikini bottom.
He pulls it aside, revealing your wet, swollen pussy.
His eyes are dark with desire, his breath hot and uneven against your face.
“So pretty,” he whispers, his gaze lingering on your exposed folds.
He slides a single finger through your slickness, coating it before pushing it inside you, slow and deliberate.
You bite down on your lower lip, trying to keep from crying out.
But the sensation is too intense. A moan slips past your teeth, and he reacts immediately, one hand shooting up to cover your mouth.
His grip is firm, but not painful, silently urging you to keep the noise down as his other hand starts to move faster, his thumb circling your clit in a way that sends sparks dancing across your vision.
You can feel his arousal pressing against your stomach, straining against the fabric of his swim trunks.
Your own desire for him is overwhelming, your body arching into his touch, begging for more.
"Hwa," you whimper into his palm, the sound muffled but no less desperate. His eyes flash with triumph, and he leans closer, his breath warm against your cheek.
"That's it," he whispers, his voice a low growl that sends a thrill through your body. "Beg for it, baby. I want to hear how much you need me."
You nod frantically, the pressure building deep inside you like a coiled spring. "Please," you breathe out, the word a needy plea. "I'm begging."
“That's what I want to hear," he murmurs, his voice thick with desire. He starts to pump both of his fingers in and out of you, his thumb relentlessly teasing your clit.
The sensation is so intense, you feel like you're going to shatter.
"Please," you repeat, breathless. "Oh, fuck–, please."
"Keep begging," he whispers, his voice a seductive rumble. "You're so close, baby. Let me feel you come around my fingers."
You nod, unable to form coherent words, as your body tightens around his fingers.
The sound of your muffled moans and the slick wetness of his hand moving in and out of you fills the tense silence of the changing room.
"Come for me," he urges, his voice a dark whisper that sends a shiver down your spine.
His finger moves faster, his thumb pressing harder, and your eyes flutter closed as you let go.
The orgasm hits you like a wave, crashing over you in an explosion of sensation.
You bite down hard on his hand, muffling a scream as your body convulses with pleasure.
When the intensity subsides, you find yourself leaning heavily against the counter, panting and trembling.
Seonghwa's eyes are still on yours, more eager than ever.
He slowly withdraws his hand, and you can feel the wetness he's left behind.
"Now, turn around," he says, his voice still a soft command.
You obey, the cool marble against your back as you face the mirror, watching his reflection as he stands behind you.
The sight of his strong, tanned body, the water droplets still clinging to his chest, makes your legs wobble.
Seonghwa's eyes are dark with need as he unties the strings of his swim trunks, letting them fall to the floor.
His cock springs free, thick and erect, and your heart skips a beat. "Look at me," he says, his voice low and urgent.
You turn around, eyes locked on his reflection in the mirror, watching as he takes a step closer. You can feel the heat radiating off of him, and you know you're about to be consumed by it.
He places his hands on your hips, gently turning you to face the mirror.
"You're gonna watch me fuck you," he murmurs, the words sending a fresh surge of arousal through your body.
He positions his cock at your entrance, the head nudging against your swollen clit.
"You ready?" he asks, his voice a low rumble that vibrates through your chest.
You nod, unable to find the words to answer. He chuckles, a sound that's both sweet and sinister, and then, with one smooth, powerful thrust, he's inside you.
You gasp as he fills you completely, the sensation of his thickness stretching you out almost too much to handle.
He pulls back almost all the way before sliding back in and staying there, each inch a delicious torture that makes you arch your back and bite your lip to keep from screaming out.
The sound of your wetness filling the small room is the only sound louder than the pounding of your heart.
"Look at yourself," he murmurs, his voice a dark caress. "Look at how much you want this."
You bite your lip, unable to hold back a moan as he stretches you open. "Oh, fuck," you murmur, your voice a hoarse whisper.
Your eyes are glued to our reflection, watching his cock disappear inside you.
"Do it," you whisper, the words a shaky command.
Seonghwa starts to move, his hips rolling in a slow, steady rhythm that builds the pressure back up inside you.
His grip on your hips is firm, his eyes never leaving yours in the mirror as he fucks you with a deliberate intensity that has you gasping for breath.
"That's it," he says, his voice a low rumble. "Take it all."
The sound of skin slapping against skin fills the changing room, the slick noise of his cock moving in and out of your pussy a delicious noise of need.
"You're so fucking perfect," he groans, his strokes becoming more erratic.
Your eyes never leave the mirror, watching as your body responds to his every movement.
You can see the tightness in your abdomen, the way your tits bounce with each thrust, the flush spreading across your cheeks
His hand moves down to your clit, and the sight of his fingers working you sends another jolt of pleasure through you.
"S-shit," you whine, the words escaping your mouth like a prayer. "Hwa, I'm gonna come again."
"That's right, baby," he groans, his breath hot against your neck. His fingers dance over your clit in a pattern that you've never felt before, his rhythm matching the pace of his hips as he drives into you.
You can't help but let out a high-pitched whine, your body moving in sync with his.
Your legs are shaking, your core tightening around him as you climb towards that sweet release. "Fuck– I’m gonna–.."
"Come for me," he murmurs, his teeth grazing your earlobe. "Let me feel it."
His strokes become more deliberate, his eyes never leaving yours in the mirror. "I wanna see you fall apart."
You nod, your voice a desperate whimper. "I'm... I'm almost there." The words barely leave your mouth before you're there, your body seizing around him as a second orgasm rips through you.
He groans, his grip tightening as he fucks you through the waves of pleasure, pushing you past the brink of what you thought possible.
Your eyes lock with his in the mirror, and you can see the challenge in his gaze.
"I'm... I'm there," you gasp, your voice shaking. "Hwa, I-I'm there."
But he doesn't stop. If anything, he fucks you harder, faster, his fingers on your clit a blur of motion. "Again," he murmurs, his voice a command.
"I want more." His hips smack against yours, the sound echoing in the tiled room, and you feel yourself rising towards that peak once more.
You try to protest, to tell him it's too much, but the words are lost in a moan that turns into a scream as your orgasm hits you like a wrecking ball.
Your knees buckle, but he holds you up, never breaking his rhythm. "Don't stop," he growls, his voice thick with his own desire. "I'm not done with you yet."
As the tremors of your climax subside, he pulls out, leaving you feeling empty and desperate for more. "On your knees," he says, his voice hoarse and urgent.
You do as you're told, your legs unsteady as you sink to the cold tile floor. He steps back, giving you a clear view of his cock, still rock-hard and slick with your arousal.
"Open your mouth," he commands, and you obey without hesitation. He strokes himself, watching you. "I wanna see those pretty eyes of yours when I come."
"Please," you beg, the word a desperate chant.
Seonghwa's eyes darken as he continues to stroke himself, with increasing speed, watching you with a fiery intensity. "Look at me," he murmurs, his voice low and seductive. "Keep looking at me."
"I need it, Hwa" you whine, the ache in your voice clear.
"Beg for it," he says, a smirk playing on his lips. "Beg for my cum."
You whimper, the filthy words making your heart race. "Please," you whisper, your voice shaking. "Please, I want it."
He's so close, so incredibly close, and the thought of feeling him come on your face, in your mouth, sends a shiver of excitement through you.
"I'm gonna cum all over your pretty face," he says, his voice tight with restraint.
You nod, your eyes never leaving his. The anticipation is unbearable, your body thrumming with excitement.
You open your mouth, tongue flicking out to taste the salty cum beading at the tip of his cock.
With a final, powerful stroke, he comes, spurts of hot cum hitting your cheeks, your chin, your open mouth.
You catch as much as you can with your tongue, eagerly lapping up the salty liquid as it pools there.
His eyes are locked on yours, watching your every move.
"Swallow it," he whispers, his voice a dark command. You do, eagerly, savoring the taste of him, the feel of his warmth in your mouth.
He reaches down, gently wiping a stray droplet from the corner of your mouth with his thumb.
"Good girl," he murmurs, the praise sending a thrill through you.
You stand on shaky legs, breath still coming in shallow pulls as the heat between you simmers into something quieter — warmer.
Seonghwa's hands settle on your hips, grounding you. His eyes search yours, still dark with desire, but softened now.
He brushes a knuckle along your cheek, smearing a bit of moisture away. “You okay?” he asks, voice low and gentle.
You nod slowly, your lips curving into a dazed smile.
"That was..." you start to say, but the words fall apart, you couldn't find the words to describe the intensity of what you just shared.
He leans in, pressing a slow kiss to the corner of your mouth.
"Incredible," Seonghwa finishes for you, his voice a gruff whisper. "But we're not done yet."
"What do you mean?" you ask, breathless.
Seonghwa's smile is wicked as he pulls out a small marker from his pocket. "In case you forget," he says, his tone teasing.
He uncaps the marker and, with a gentle touch, scribbles his full name and number along the inside of your wrist.
The coldness of the ink contrasts with the heat of his skin, sending a thrill up your arm.
"Park Seonghwa," you whisper, the name feeling strange but somehow right on your lips.
He looks at you, his eyes dark and intense, the connection between you palpable. "Call me," he says, his voice a low rumble that sends a shiver down your spine.
He leans in, capturing your mouth in one final, lingering kiss.
His tongue traces the seam of your lips, dipping inside to tangle with yours.
When he pulls back, your eyes are hazy with desire, and your body feels like it's on fire.
With one last look, he tucks the marker back into his pocket and grabs his towel, wrapping it around his neck.
"See you around," he says, his voice a seductive promise.
He opens the changing room door and steps out, leaving you standing there, trembling with the aftershocks of what just happened.
You watch him go, his muscular body disappearing into the bright sunlight.
The sound of laughter and splashing from the pool outside feels like it's a million miles away as you touch your wrist, feeling the warmth of his ink on your skin.
Finally, you take a deep breath, willing yourself to move. You pull on some fresh clothes, the fabric sticking to your damp skin.
The scent of chlorine is still in the air, a reminder of the explosive passion that just unfolded in this tiny, private space.
But as you watch him walk back to his tower, his eyes finding yours for a brief moment, you know that you can't resist the pull.
You're in too deep now, and you don't want to be anywhere else.
With shaky hands, you grab your phone and save his number, the digits forever etched in your mind.
As you head back to your chair, you can't help but feel a sense of anticipation building in your chest.
And as you lay there, the sun warming your skin and the sound of the waves crashing in the background, you can't help but wonder what happens next.
Will you call him? Will he call you? Or will you just stay here, tangled up in the heat of it all, letting the memory of his touch and his taste linger on your skin like the chlorine from the pool?
The possibilities are endless, and you can't wait to find out.
