Work Text:
Most of the beach was awful, and Kei avoided it if he could.
But, in the morning, whilst his father and Akiteru slept, Kei tip-toed down to the tide pools.
It was the only place on the beach that bore any solace to Kei. He loved to watch the little creatures twitch and blob about. Starfish dancing ochre, juniper, amaranth. Oysters skipping to and fro. Tiny crabs liked to burrow in the sand, and Kei would often pick them up and let them teeter about in his palm, nipping the soft skin.
That day, there was nobody was at the beach yet. Kei hummed to himself as he padded along the sand. His footprints welled with seawater - the tide had only just pulled back. Plenty of critters to be found in the tide pools, then. Cool.
Kei had been initially looking for an octopus, when a splatter from one of the pools caught his attention. Upon further investigation, he found a bizarre sight.
There was a small shark in the tide pool.
Kei looked around the empty beach, the sky above still struggling to wake out of its marmalade dawn. He was searching for a culprit, a perpetrator of sorts. Alas, the beach was vacant for anybody but him. And Kei liked it that way. Normally.
But the shark burbled from the shallow tide pool. Kei clucked his tongue, hovering around it cautiously. If he didn’t do something, it would probably die.
“How’d you even get there, hm?” Kei muttered, crouching down. The little shark just bobbled about. Behind Kei, the waves folded in on themselves, the moon peeling back its turquoise blanket, answering Kei’s question. “Harsh tide? Unlucky you.”
Still, Kei wasn’t just going to leave it there. He took a deep breath, before clutching the shark with both hands.
It flailed in protest, waggling as Kei hurried from the tide to the pitiful boardwalk. It only sprawled twelve or so feet across the water, but still, the depths there would be enough for the shark to find its own current. Kei grit his teeth, admittedly terrified of its erratic movements.
“Calm down,” Kei said to it, looking across the transparent waters, searching the teal for a suitable deposit point. From within the water, a flutter of kelp caught Kei’s eye. A thick bundle of it, swaying with the water, likely torn from a kelp forest. Perfect.
“There's probably a fish in there for you.” Kei nodded a curt farewell to the shark, and then let it fall from his hands into the water. It crashed into the kelp.
And then a blood-curdling screech erupted from the waters.
Kei jumped back as he watched somebody burst out from the sea, screaming bloody murder. It wasn’t kelp. It was a guy, splashing erratically, shrieking as he tried to swim away from the tiny shark.
“Ah- up here,” Kei called urgently. The guy didn’t need any further coaxing, taking Kei’s outspread hand and hurriedly lugging himself atop the boardwalk. The momentum of the movement made the two boys fall onto the spindly wood, both of them coughing as the wind got knocked out of Kei and seawater left the guy’s lungs.
The sky was finally teetering into a cloudy blue, the rising sun delighted to watch Kei embarrass himself. He scowled upwards as he heaved.
“Did you really have to scream so loudly? It wasn’t that big-” Kei began, sitting upright to glower at the guy. He’d been looking forward to being the only one at the beach, and…and…
…wow.
Seawater fell from the boy’s algae hair, the locks curling with salt and framing his sharp face. Freckles spluttered all down his honeyed-over skin, sand under a microscope, each cluster seemingly multiplying the longer Kei’s eyes lingered. He followed water droplets as they ran down the lines of muscle straining across the boy’s lithe frame, mildly jealous of their journey across that gorgeous expanse.
The boy was pretty. So pretty. And he had such sweet eyes, rich sand dollars, staring right back at Kei-
“Did you throw a shark at me?!”
Oh. Right.
“...I didn’t realize you were there.” Kei mumbled truthfully.
Before he could stop himself, Kei reached out to gently tug a strand of the boy’s hair. Some of the water squeezed onto Kei’s palm. He clenched his hand into a fist to keep the precious droplets safe. “I thought you were a bunch of kelp or something.”
It wasn’t intended as an insult, but Kei had still expected the boy to be upset by the comment. Suffice it to say, Kei found himself surprised (and going hot) when the boy burst into giggles, whole body shaking with delight.
“Kelp!” He ran his hand through his hair, slicking it back, bestowing more of that lovely smile. “Well, your hair looks like it's hiding stargazers in it.”
“...the fish?”
“Yeah, the ones that bury themselves in sand!”
“Oh.” Kei grinned before ducking his head. “Double-check for me.”
He couldn’t see it, but he was certain the boy was smiling too, hands shockingly warm as they swam through his puffy curls. Kei took the opportunity to admire the freckles that disappeared up his shorts, a tantalizing trail, practically whispering for Kei to follow.
“Fish-free.” The boy decided, giving Kei’s hair one last ruffle before pulling away. Had it been anyone else, Kei would have slapped their hand away. But this guy’s touch was so gentle, so good. Kei wanted more of his hands in his hair.
“I’m kind of disappointed.”
“Same. You would’ve been a really cool merman!”
Kei looked the boy up and down, stare floating around his hips, picturing where that lustrous bronze would gleam into emerald scales. He compelled drool to stay behind his teeth. “You too.”
The two of them sat under what would’ve been an awkward silence, but some slight clacking noises cut through the tension. Kei turned his head to the bucket the boy had been carrying, now askew on the boardwalk.
“What's that sound?”
“That’s Sebastian! The whole reason I was in the water,” The boy grabbed the bucket, expression squeezing into woe as he peered inside. “Oh no, he cut off some of the starfish’s arms!”
Baffled, Kei leaned over to also look inside. A little crab pottered about, clicking its pinchers, a proudly decimated starfish beside it.
“Sebastian. So did you name the starfish Ariel?”
The boy winked at him, and Kei could’ve choked. “Well-versed in your Disney lore. I like it.”
They smiled at each other for a moment, Kei luxuriating in the funny feeling in his heart. He wanted the boy to wink at him again. To keep looking at him like that. To-
The crab crawled up and clamped down on Kei’s nipple.
Kei had never considered himself a particularly effeminate person, but the scream he let out could’ve easily been mistaken for a little girl’s. He continued to shrill, flailing as the crab gleefully remained latched to him. The boy’s mouth hung open, but no sound came out, petrified as he watched Kei fumble with the crab.
“Get it off! Get it off!”
“H-how?!”
“Do anything, idiot!”
He did, indeed, say anything. Still, Kei wasn't expecting to get punched. He flew right off the boardwalk, the feeling only merely alleviated by the startling cold of the water. Kei struggled in the cold waves, torn between bruising agony and being baffled as to why, why, why the fuck had the boy punched him?
Kei’s complaining ceased when he felt warm hands loop around his torso, lugging him up through the sea. The water stung at his sore chest, but otherwise, Kei was far more fixated on the dizzying way he melted against the boy’s skin. He could feel every grit of sand, every subtle flex of sinew, and the salt in the water practically kissed their way up those freckles. Kei ached to do the same.
Eventually, the boy dragged them both onto shore, dumping them upon the damp sand beneath the boardwalk. Though the sky was still only just cresting into daylight, the boardwalk’s shade offered relief in waves. Kei skimmed his eyes up and down the boy’s body, faintly wondering (for no particular reason) if there was anyone else on the beach.
“I’m so sorry,” the boy blurted out, blinking salt out of his long lashes. His face was a little red. It was driving Kei insane. “I didn’t know what to do! I panicked and I- I just-”
“Whatever.” Kei cut him off, looking down to his chest, wondering how dark of a bruise it’ll leave. He hoped it would blither into the same strange yellow as the boy’s eyes.
Then tanned fingertips were upon him.
Granted, they were gentle, courteous, palm refusing to overstay its welcome as the boy skimmed over Kei’s sternum. Still, Kei had to keep himself from dropping his jaw at the insane way the touch bled into him. How did something so simple feel so intense?
“I hope it doesn’t hurt much.” The boy quietly murmured.
Hot. Hot. Hot. The touch was so hot. The whispering was so hot. Oh God, this boy was so hot. Kei didn’t know what to do with himself, marveling at the smooth planes of his body. No wonder people fell easily to the touch of gods - Kei was sure that this boy could coax him into a slaughterhouse.
The tides lapped at the shoreline, the sound amplified beneath the old wood of the boardwalk. As it swept in and out, Kei watched it swallow up some seashells, waves greedy as it lapped at the sand. He saw the way the water was eyeing up the boy. Kei refused to give him up.
“...what’s your name?” Kei muttered, uncertainty anchoring his words to his teeth. It didn’t even sound like a question, really - the boy pulled his hand back momentarily, but Kei leaned closer, heart shrieking when scorched fingers met his skin again. Kei was never this desperate, this needy, not with anyone. His sandcastles were squat and square and far from shore. But with this boy…
“My name?” The boy said, somehow still radiant in spite of the shade, bioluminescent as he moved. His hair waved in coy curls, inky waters beckoning Kei closer. “It’s Yamaguchi Tadashi.”
Pretty. Delicate. Easy on the tongue. Kei wanted to dive into the sea, into depths unfathomable to his lungs, and scream the syllables until the whales spat him back into Yamaguchi’s hold.
“Yamaguchi,” He breathed, the name taking life, kissing Kei on the cheek as it left his tongue. It made both of them blush to hear it. Glorious.
“So- um, you are…?”
“Tsukishima Kei.”
“Tsukishima…” Yamaguchi tried, voice draping the letters like betta fish fins. Kei’s name had never sounded so good. He wanted to hear Yamaguchi say it over and over again.
“Um,” Yamaguchi nodded, shyly avoiding Kei’s eyes, staring instead at Kei’s legs. Kei deliberately shuffled closer, goosebumps prickling up his thighs as his shorts rode up slightly. He relished in the sweet way Yamaguchi stammered at the exposed skin, deliriously excited at the way a few millimeters of his skin was enough to make Yamaguchi fluster. “Do…do you live around here?”
“No. I’m visiting.”
“Oh.” Yamaguchi twitched a little when their knees bumped, marveling up at Kei. He looked incredible, blushing coral pink, as if he couldn’t believe the attention Kei was giving him. Doesn’t he know that he’s the pretty one here?
Sunbeams were beginning to pour through the boardwalk above them, bathing Yamaguchi effervescent. The new washes of gold atop Yamaguchi’s face called to Kei like the esca of an anglerfish, speaking to him like whale clicks. He couldn’t possibly tear himself away from Yamaguchi, not now. Perhaps not ever.
He’d never felt this dizzying allure, had never been captured by anyone quite like this. It felt like Yamaguchi had braced a speargun over his heart - Kei wanted to clutch the weapon and lodge it into himself.
Spurred by the threat of never seeing him again, Kei leaned even closer to Yamaguchi, their lips mere twitches away from each other. Yamaguchi’s mouth parted, and as much as Kei wanted to kiss him breathless, he instead focused more so on coaxing Yamaguchi into swimming alongside him, two butterflyfish, bubbling together through every reef.
“I’m here every weekend,” Kei began, fighting not to grin when Yamaguchi shivered. “How come I’ve never seen you before?”
“...I…” Yamaguchi’s eyes flitted from Kei’s eyes to his lips, wonder pulsing in his pupils.
Then he snorted, startling Kei.
“I don’t talk to boys that throw sharks on me.”
“Well, I shouldn’t talk to boys that punch me, but here I am.” Kei argued, though he was snickering with Yamaguchi now. God, he looked good, face scrunched with delight. Kei wanted to bite him. Really, really badly.
“I am sorry about that, really. But, um,” Yamaguchi experimentally splayed his hands onto Kei’s own, shaky fingers exploring sapphire waters. Kei’s breathing spiked, his breaths puffing out over Yamaguchi’s lips. “Well, I think you might’ve liked it.”
Kei felt himself flutter through any number of pinks, a mimic octopus plastered to an iridescent surface.
“...A little bit.” He finally muttered. Yamaguchi beamed, delighted, shyly leaning closer.
Look. Kei had never kissed anyone before. He didn’t know what to expect, and only had some semblance of what to do. He was certainly not the type to fantasize about it. He was absolutely not the type to regard the concept with novelty. And he definitely wasn’t the type to kiss strangers while on weekend trips.
But he couldn’t help it. Kei closed the gap between them, driven entirely by feverish awe. The little squeak Yamaguchi let out was absolutely glorious, and Kei could feel his dark lashes brush against his cheeks when he shut his eyes. His tongue tasted like salt, but he was searing hot all-over, making Kei’s heart beat funny. It felt like he’d be dragged underwater, bubbles fluttering from his nose and whirring fast in his ears.
Yamaguchi hummed against him, smiling lightly, face wondrously warm. It was as though he was slowly boiling Kei alive, burning him lobster-red. Kei gasped when Yamaguchi’s hands finally grasped at his legs, fingers slyly creeping up his shorts.
“Can I…?” Yamaguchi drew back by millimeters at most, huffing against Kei’s still-parted mouth.
Kei didn’t reply, far too focused on kissing Yamaguchi again, chasing the sensation. He felt like he’d been sitting in a hot bath for too long, skin soft and pliant when Yamaguchi petted at his thighs. So soft. So gentle. And yet not nearly enough. He wanted Yamaguchi to pry his shell open and tear him apart.
As a means of encouragement, Kei laved his tongue over Yamaguchi’s jawline instead, heart dropping when Yamaguchi made the sweetest, strangled noise. He had really only intended to free up Yamaguchi’s teeth as a prompt, but he’d instead allowed the boy to creen and murmur ragged praise right into Kei’s ear. As if he couldn’t get any hotter, Kei lamented, twitching in Yamaguchi’s hold.
“Tsukishi…Tsukki… hah,” Yamaguchi could barely mumble out, squeezing Kei tighter. He slid a hand over Kei’s crotch, palming him through his shorts and making Kei’s head swim. All the air had fled his lungs, Kei’s heart only beating in time to the way Yamaguchi’s hand rolled. “Do you like that…?”
“Idiot.” Kei nipped him, making Yamaguchi giggle. It really felt like the world was wobbling beneath him, the dependability of the sand wavering in the wake of Yamaguchi. He sucked and bit his way down Yamaguchi’s neck, obsessed with the way Yamaguchi’s pleading was drowning out the tides. “Don’t stop.”
“It’s- I- Tsu- mhm!”
And then there are hands on Kei’s shoulders, prodding him to lay on the sand. It was damp, and Kei winced for a moment, until Yamaguchi’s pretty face was leaning over him again. He blinked upwards, completely possessed by the high blush in Yamaguchi’s face, in the hot pants he was breathing, in the way he seized control of Kei’s inhibitions and drowned them out. No wonder pirates fell for sirens.
Yamaguchi giggled. “What?”
“What?”
“You think I’m a siren?”
Oh. He’d said that aloud. Fantastic.
Kei would’ve draped his arms over his face, but Yamaguchi was still pinning them down. Instead, he grumbled and cast his gaze aside, ruby-red as Yamaguchi kissed his cheek, willing his skin to scorch those soft lips.
“Well, if you were a pirate, I’d try to kill you.” Yamaguchi offered, and Kei wished he could’ve been ashamed at how hard that made him.
It sure felt like Yamaguchi was trying to kill him, what with way he weighed against Kei’s hips. He was concrete blocks tied around Kei’s ankles. He was turbulent currents swooning over Kei’s body. He was sand at the bottom of the ocean, waiting to cradle Kei when he fell to sea floor. Kei wanted to sink faster.
Yamaguchi ducked down, lapping at Kei’s collarbone and sucking hard. It’s immediately too much for Kei, who fights for purchase with the worthless sand beneath him. He swapped his grasp to Yamaguchi’s hair, who is seemingly thrilled by the change, as evidenced by the enthusiastic way he deluged Kei’s chest with kisses and bites. Every so often, Yamaguchi bit a little too hard, and it felt a bit like he was ripping chunks out of Kei’s skin. It felt incredible.
“What’s with you and my chest?” Kei managed to hack out between his helpless whining.
“It’s really pink,” He felt Yamaguchi smile against him, biting Kei’s nipple and making Kei gasp.
“I’ll be black and blue at this rate,” Kei huffed, but Yamaguchi’s little snort immediately snapped a smile on his face, a diver flipping a shark upside-down.
“Tsukishima…” Yamaguchi leaned back on his legs, looking around him. Seagulls hollered from above, the sun determinedly high in the sky. They were still beneath the boardwalk, but that admittedly wasn’t much cover. Though, the way Yamaguchi eyed him, with his lashes low and lip caught in his teeth, told Kei that perhaps he didn’t care so much. “Do you want to keep going?”
Kei looked down to his stinging chest, where it looked like an octopus had latched onto him, before looking back up to Yamaguchi. “I think we’re past the point of return, Yamaguchi.”
Yamaguchi dreamily traced the marks he’d riddled Kei with. He grinned, teeth catching stray light, sparking hot threats of danger in Kei’s heart. “I think so too.”
Kei wriggled beneath Yamaguchi’s weight, to little avail. “Well? What are you waiting for?”
“I’m just wondering what to do with you,”
Well then. Kei was effectively stunned into silence, watching Yamaguchi’s eyes dart over him, bait on a hook, calling Kei closer and closer to his ship.
“Er-!” Yamaguchi seemed equally surprised by his words, shamefully covering his face with a hand. “Jeez, that sounded creepy, didn’t it? Sorry, Tsuk-”
“Shut up, Yamaguchi.” He breathed, tugging Yamaguchi back to his lips. He didn’t really know what he was doing - all he knew was that he wanted Yamaguchi atop him forever. It felt like Kei was being diluted, tough sand falling into murk as Yamaguchi rolled his hips against him. He marveled at how warm he was, how dizzyingly hot he felt, how every touch felt like the spark of an electric eel.
“O-okay. I’ll…” Yamaguchi pulled back, breathing hard. “I’ve never done this before, so, just, lower your expectations.”
Yamaguchi could’ve torn out Kei’s ribs and ripped his heart and spat it back unto Kei, and Kei would’ve just laid there, bleeding out and dreamily staring up at him. But he decided that Yamaguchi maybe didn’t want to hear that right now.
“Sure.” He nodded, heart banging as he watched Yamaguchi maneuver down Kei’s body, stalling over the blatant tent he was pitching. “What are…?”
Kei swallowed harshly when Yamaguchi tugged at his swim shorts, feeling mortified and captivated and shamefully excited. A strange sensation indeed, but it thrilled Kei to no end. A foreign giddiness washed through Kei’s blood as he watched Yamaguchi’s tentative movements.
Embarrassingly enough, Kei’ dick was blushed harshly at the tip, slick with pre-cum and aching in Yamaguchi’s hold. As heated as he felt, though, Kei fought not to whine or buck up.
“Whoa,” Yamaguchi laughed nervously, tongue swiping over his lips as he marveled. “I didn’t do that much to you…”
“Shut up,” Kei hissed, writhing. He clamped his lips when Yamaguchi finally lapped at the tip of Kei’s dick, shy, tongue flat as he spread pearls of pre-cum over the slit. He drew back to gauge Kei’s reaction, and a thick line of spit and cum followed his tongue. Kei felt damn near manic - who allowed this boy to have such big eyes? Such long lashes? Such pink cheeks?
“You taste nice,” Yamaguchi remarked, seemingly pleased. He tongued at the cum on his lip. “Really nice. Can I keep going?”
“Why are you even asking?” Kei weakly snapped back, certain he was beyond crimson at this point. Yamaguchi just shook the hair out his face, laughing, leaning up to kiss Kei’s cheek briefly. It was sticky, and Kei should’ve felt disgusted, but he couldn’t possibly. He and Yamaguchi were well-sequestered in blooms of anemones, hidden away from everyone and everything, and Kei wanted Yamaguchi to do even worse things to him.
“Crabby,” Yamaguchi bit at Kei’s thigh as he shimmied back down, beaming against Kei’s skin. Kei had never realized how nice a smile felt. “Heh, get it?”
“Because of the crab earlier, yes. Hilarious.” But Kei was smiling back, thoroughly doped up on whatever venom Yamaguchi’s touch beheld.
Yamaguchi took Kei back into his mouth, movements timid, albeit dizzying. Immediately, Kei had to clutch hold of Yamaguchi’s hair, gasping when Yamaguchi slicked his tongue down the underside, right where it was most sensitive. He felt as though Yamaguchi was plucking out each and every one of his splines, finger tracing against each gill, no scale left untouched. A pufferfish making determined murals in the sand - Kei could easily imagine spending the rest of his life curating the perfect display for Yamaguchi, selecting only the shiniest shells and softest sand, living the rest of their days blub-blub-blubbing throughout the sea.
Kei thrashed fitfully beneath him, heart fluttering, mussel tissue twitching. As plain of a goldfish as he was, every bob of Yamaguchi’s head shot another spark through Kei’s very soma, leaving him wondering how it was possible for someone to take his measly fins and flourish him into an angelfish. Yet another testament to Yamaguchi’s glory.
And, because Kei wasn’t helpless enough already, Yamaguchi found the nerve to moan and whine around Kei’s dick, drool swimming down his chin and reefs of red coral splaying across his cheeks. Kei could’ve sworn he saw Yamaguchi’s freckles darting around like minnows, though he was quite hazy at this point.
“Yamaguchi, I-!” Kei tried, thighs shaking around Yamaguchi’s head. He was drowning in waves of ecstasy, each tide crashing harder than the last - both his grasp and resolve totally crumbled against Yamaguchi’s tongue. “Keep, hm, keep doing that.”
Yamaguchi blinked up at Kei, mouth full and breathing hot - a devastating visual. Kei screwed his eyes shut and fought not to cum there and then. “I’m close, I'm-”
And then there was cool air flooding over Kei’s dick, Yamaguchi’s lips glossy as he drew away. The sudden temperature change offered, almost jokingly so, a half-second of clarity to Kei. He used the moment to wonder if this was how chewed-up fish felt when whales spouted them back out.
“Hey,” Kei grimaced at how raw his voice sounded, croaky, but he couldn’t care at the moment. Yamaguchi was looming above him now, planting himself up on Kei’s thighs and tucking his hair back behind his ear. His skin was lavished with sweat, making his tanned skin shimmer, sinew pulsing like jellyfish. “Why did…?”
“I wanted to make you cum with my hands,” Yamaguchi shrugged apologetically. Kei could’ve disintegrated then and there.
“...you suck.”
“Literally.”
“Yeah.” Kei took a deep breath, shutting his eyes, grateful when Yamaguchi snickered and patted Kei’s arm. “You’re awful, Yamaguchi. Not even dolphins would do this to their food.”
“Stop being so hot, then.” Yamaguchi hummed, before pausing to consider Kei’s words more carefully. “Wait, food? I’m not going to eat you!”
“You’ve been giving it a pretty good try.”
“Don’t tempt me, Tsukishima,” Yamaguchi stuck his tongue out at him, before taking Kei’s dick in his hand, pumping easily with the combined slide of pre-cum and saliva. "Yeah. This’ll be easy, now.”
“No one’s called me ‘easy’ before.”
“Not you.” Yamaguchi giggled.
“Then what?” Kei groused, irritated, but fondly so. How glorious it was to find someone who could bear him whole-heartedly. “What are you plotting?”
“I just wanted- here, let me show you.”
Kei didn’t bother to draw up any expectations, because he knew Yamaguchi would shatter them instantaneously. He watched, breathless, as Yamaguchi wiggled his own shorts down to his thighs, skin scalding as his dick finally burned against Kei’s own. If Kei had held any sliver of rational thought at this point, it was effectively destroyed when Yamaguchi took both their dicks into his hands. Clasped, his palms created a tight vessel, heated and insane and completely intoxicating. Kei could feel Yamaguchi twitch now, every glorious tremor of his thighs branded proudly against Kei’s skin.
“See?” Yamaguchi panted, offering an experimental rut, as though he somehow felt that Kei hadn’t been convinced at this point. “You can hold onto my hips. I-if you want.”
“You couldn’t tear me off of you,” Kei bit his lip at the sensation, holding onto Yamaguchi’s legs for dear life, heart only rattling harder when Yamaguchi laughed.
After taking in a determined breath (puffing up his cheeks and everything, as if Kei wasn’t already woozy from blood loss), Yamaguchi twitched forward in tepid jerks, pace shy, carefully watching Kei’s eyes. Kei figured there wasn’t much sense in playing coy with Yamaguchi at this point.
“Good, good,” Kei mumbled, voice jumping with Yamaguchi’s little ruts, fighting hard with his head to say something coherent. “Yamaguchi, that feels really- hah.”
“You feel good, Tsukis- Tsukki- it feels good?”
“Mngh-!”
Oh, to hell with graspable conversation: Yamaguchi could see him falling to pieces. Kei didn’t need to explain anything - Yamaguchi would just get it.
Instead, Kei let his mouth part and his brain shut off, totally at the mercy of Yamaguchi’s increasingly-ragged pace. He was making sounds he didn’t know he could make. He was feeling things he didn’t know he could feel. He was seeing things he didn’t know he could see. Yamaguchi was the magical blue of the abyssal plain, harnessing the mystique of every drop of the sea and confounding Kei with it all at once.
“I wish you could fuck me for real, Tsukki- mm!” Yamaguchi intercut his thoughts, a swordfish darting through the dark, slashing heartily. He was bucking wildly now, hair flaring dizzyingly, hands squelching as he somehow tightened his grasp around the two of them. “I wish I could feel you in me. You’d feel so good, I know it, I know it-”
“Are you trying to kill me?” Kei cried. Like, seriously, he could not sit there, fucking against Kei and crying his name and begging like that. He’d put Kei in the world’s greatest early grave.
“I’m sorry, I’m sorry, I’m sorry!” Yamaguchi whined over and over, head and mouth dropping, looking radiant as he trembled atop Kei. As if that helps!
Kei just committed himself to permanently inscribing their seahorse dance to memory, Yamaguchi’s cries the melody and his fervid fucking the steps. In this haze, he momentarily fantasized about actually dancing with Yamaguchi, somewhere along the beach, flowers in their hair and sun melting purple behind them. Kei chided himself for how intensely he pined for it.
“A-ah, Tsukishim- mm! I can’t-!” In an effort to achieve a better angle, Yamaguchi’s leaned more of his weight forward, huffing a lot closer to Kei’s ear - absolute heaven. Kei’s legs had begun to ache, but he couldn’t care less. He wanted Yamaguchi to use more teeth, more venom, more everything. He wanted those pretty hands to shove him underwater and waterboard him endlessly. He wanted to be cast adrift with nothing but Yamaguchi’s touch to satiate him - Kei’s certain he could last a lifetime on a desert island with just the thought of Yamaguchi to tide him over.
“I wouldn’t spell out S.O.S. I’d draw you.” Kei said, brain completely unable to conjure the concept of embarrassment, of rationale. “N-no. Your freckles. I’d draw those.”
“For what? If you- hm! If, like, you were stranded somewhere?”
“Uh-huh.”
Yamaguchi didn’t say anything for a moment, hips still pumping relentlessly. For a fleeting beat, Kei wondered if perhaps he’d been too honest. If maybe he’d poured too much blood in the water. His orgasm began to crest within him, licking hotly at his gut - Kei supposed it was inevitable. He, as a person, was too much, murky tuna that must be contained in oily cans. Maybe he should just let the waves wash his deluded self back ashore.
But, with the magical dazzle of a thresher shark, Yamaguchi’s teeth gleamed as he smiled, leering down at Kei and whipping hot splashes of arousal through his blood again. Effectively, all of Kei’s doubt was silenced, crackling shivers swimming up his spine. It’s as though his heart could hear itself pumping within Yamaguchi’s electroreception, danger shrieking through his body. He loved it. He loved it. I love him, Kei decided.
“Nobody would come save you, if you did that.” Yamaguchi finally said, face close to Kei’s, eyes iridescent and pupils swallowing Kei whole. “But still. I’d find you, Tsukki.”
How utterly embarrassing for Kei to be so turned on by such a stupid conversation. But he couldn’t possibly help it. As soon as the words smoothed over Kei’s ears, each letter drenched with such blatant desire, he was done for. Nobody would ever, ever meet the standard that this boy had set.
Kei was grateful when Yamaguchi swallowed his whines in a deep kiss, though he knew he was still being terribly loud when he came. Starfish sparkled behind his eyes as he rode out his orgasm, cum melting between them like a fishnet, tangling them both in Kei’s hold. He held onto Yamaguchi like a lifeboat, arms flailing around his freckled shoulders, body fighting to stay afloat but mind begging to drown alongside this boy again and again.
Eventually, Kei was able to draw back, breathing exceptionally hard and mind bleary as anything. Yamaguchi was looking at him like he’d found treasure. Had he an ounce of energy left, Kei would’ve told him that he was one that really looked like gold.
“So cute,” Yamaguchi kissed Kei’s cheek, ducking to lap at the drool that had crept down Kei’s lips. Kei bit Yamaguchi's tongue softly, grinning when the boy giggled. “You look so sunburnt.”
“Yeah, well.” Kei fought for a reply, but his mind was terribly groggy, every fissure too soaked in seawater to possibly offer function. He threw his hands up in defeat, and Yamaguchi laughed properly now, shaking against Kei’s chest.
“Come on.” Yamaguchi began to tug Kei up, stopping to gently tuck themselves back into their shorts. Kei mutedly realized that Yamaguchi hadn’t cum yet, but strangely, his energy still hadn’t resurfaced enough to conjure protest. He found himself unable to resist as Yamaguchi dragged them into the water, tide eager to swallow them back into the sea. “Ooh, the water’s all warm from the sun.”
“Hey…you didn’t…” Kei tried, puzzled by how exhausted he felt. Surely, he wasn’t this feeble? He could barely stand in the water, leaning most of his weight on Yamaguchi.
Yamaguchi smiled sadly at him, head on Kei’s shoulder lacing their hands together. “I want to, really, but I couldn’t stay out of the water for much longer.”
“...huh?” What was he talking about? What was this fog cast over Kei’s mind? Why was it so hard to stand?
Though not loud to begin with, Kei’s mind quelled when Yamaguchi kissed him, sweet, serene, sincere. His eyes didn’t shut of their own volition, though. The sensation was bewildering, bewitching.
Kei couldn’t possibly keep himself upright anymore - he weakly moved to hold onto Yamaguchi's shoulders, who immediately caught Kei into his hold. He struggled to pull away from his lips, not really wanting to do so, but needing to ask questions.
“It feels weird, right? But it’ll wear off soon,” Yamaguchi kissed Kei’s cheeks repeatedly, almost like an apology. “I wasn’t lying. I’m not going to eat you. I like you too much.”
“Wh…” Kei felt himself slipping, both literally and within his own head. He wasn't sure when, exactly, he hit the water.
Eventually, when he found it in himself to stir, Kei wearily dragged himself back into lucidity. He blinked sand out of his eyes, flecks of it pouring off of him when he sat up. He was beneath the boardwalk again, sun cresting into a dark orange. Faintly, from beyond, he could see the ocean shifting, tides rolling innocuously. Kei doesn’t know what to make of the ordeal - he looked down to his body, where he was still peppered with love bites galore. How am I supposed to walk out onto the beach like this? Yamaguchi, what were-
Yamaguchi. Yamaguchi, Yamaguchi, Yamaguchi Tadashi. Where was he? What did he do? Why did he leave? Kei flitted his head around, desperate, mumbling the name to himself for fear of forgetting it, before a sight on the waters caught his attention.
From far beyond, out on the horizon, a slick tail fluttered from the water, green fins flailing behind it.
The tail, and Kei was absolutely certain of this, was waving to him.
