It hadn't even been twenty-four hours since their first time on the beach and Jungkook was already practically squirming to go again. After a surprisingly soft kiss and a few muttered words of, “Was this okay?” from the older blond, the pixie had picked up his treasures and headed back up the beach to his cave, leaving the merman sated and rather blissed out. Shit. That had changed things between them. It was now morning, however, and the younger had left his tail for once, listening to Jimin's scavenging from where he floated sleepily on his back in the lagoon.
“What're you searching for this time, hyung?” He murmured, twisting around to peer at where the blond was paddling in the shadows, hair pushed back messily from his face, frizzy where it had dried in the hot sun. If Jimin was annoyed at being called Hyung while out of their orgasmic haze, he didn't say anything.
“Sea glass.” No elaboration? Had he done something wrong..?
“Are- are you mad at me..?” Fuck. The merman felt his voice tremble ever so slightly. Yes they were still enemies but he'd been more than vulnerable last night.
“What makes you say that?” Yeah, the pixie had definitely just snapped at him. Drawing in a sharp breath, Jungkook forced himself to swim closer, pushing himself up by his forearms once he'd reached the shore.
“Oh nothing, apart from the fact you fucked me and now you're back to acting like a dick.” The pixie narrowed his eyes at that, dragging his gaze away from a pale green piece of sea glass by his foot.
“Okay, what is your fucking problem?” The elder muttered, arms crossing against his bare chest. “So what if I fucked you? You wanted it- you were practically begging for it. It didn't change anything. I still hate you.” The merman swallowed thickly. Right…
“Of course it didn't change anything. I hate you too, hyung. I just-” Just what? What did he want? Even though he still had his tail he could feel the burning arousal beginning to course through him, settling deep in his belly, “So it's never going to happen again?”
“What?” Jungkook felt shame join the feeling of arousal at the look of utter surprise and then mirth that spread onto Jimin's face.
“Nothing. You misheard me, hyung.” Even he knew he was being a brat as he crossed his arms and averted his gaze, staring down at the little droplets of sea water glistening on his tail.
“No I didn't. Fuck- you want me to fuck you again, don't you?” The raven head glowered at the scoff following the elder's words, “You want me to bend you over right here and take you. Even though I'm a pixie. Even though I'm shorter than you.” Silence. Jungkook didn't want to give the other the satisfaction of being right.
“No…” His words sounded weak even to his own ears.
“What was that? No?” The merman could practically imagine Jimin's smirk, “And look at me when you talk to me-” He sucked in a sharp breath at the sudden grip on his chin, soft hands dimpling his skin as his gaze was drawn to stare up at the pixie, at his plump lips and chiselled jaw, honey-brown eyes awaiting, “Go on. Tell hyung what you want.” Jungkook swallowed thickly, eyeing the other almost waringly. Was this a trick? A joke?
“And what if I do want you? What then?” The younger jutted out his jaw, determined to at least look confident in his words.
“Then you better get rid of that fucking tail and turn around.”

Shit, shit, shit. His eyes widened as he stared up at the pixie. When standing, he'd actually be almost a head taller, but here, sat by his feet, jaw in his hands, he felt so impossibly small.
“Was I not clear enough? Get rid of your tail and turn around.” Jungkook doesn't think he's ever moved so fast. One minute he's staring up at Jimin, stars in his eyes, and the next he's squirming to shed his tail, almost stumbling in his desperation to turn around, bending over before the scales had even faded away completely, “Desperate much?” He didn't even have the energy to retort back, especially not when he felt the press of lips against the small of his back, making him twitch.
“Hyung, don't tease, please.” All the merman got in response was a muffled groan and the sound of the pixie dropping to his knees, saltwater splashing against the raven head's tense thighs at the action.
“Shit. There you go.” The lips trailed lower and lower, over the swell of his ass, warm palms splaying against his tanned skin. Fuck. Embarrassment bloomed in Jungkook's stomach at the first brush of Jimin's tongue against his rim, toes curling in the sun-scorched sand.
“Wait- don't-” The younger's whiny protest was ignored, back arching further as he pushed back on the blond's tongue, honey-coloured thighs tensing as he let his eyes flutter closed. The merman doesn't know how long he stayed there, being worked open, but soon his thighs were aching and his hips were twitching, cock dribbling uselessly against the sand as he fought back teary, breathless moans. Jungkook almost sobbed at the sudden loss of pressure against his rim, dazed eyes falling shut once more at the tell-tale sound of fabric rustling behind him.
“This okay, Jungkook-ah?” His tongue felt heavy in his mouth but he forced himself to nod, back muscles rippling as the pixie slid his hand between the raven head's spread thighs to collect some of the precome that had begun to pool beneath him. The pressure this time round was heavier, despite the merman's come slicking the elder's cock, “Fuck…”
“Hyung…” Jungkook whined, forearms collapsing at the gentle shove against the small of his back, cheek pressing into the sand. He felt delirious, the sun beating down onto his back, Jimin driving into him over and over until his babbling was reduced to shameless, staccato moans.
“Shit. Turn around. Hyung wants to see you.” The merman felt limbless as he was rolled over with the blond's help, his thick thighs hooking over the pixie's slim shoulders as if on instinct, the angle pressing the tip of the elder's cock right against that spot.
“Ngh, fuck- Hyung- there, there, please- right there-” The younger knew he was being desperate, knew how he probably looked as he threw his head back, toes furling, hips rolling down to meet the calculated thrusts that were driving him to insanity. He muttered incoherent words of thanks, profanities, cheeks flushed as he writhed beneath Jimin, eyes screwed shut as tears slipped free. He was so close.
“Feel good? Shit. Being so good for hyung. Look so good. So pretty beneath me.” The merman preened at the blond's breathless words, reaching up to tug him down into a messy kiss.
“So close. ‘M so close, hyung.” All Jungkook received was a wordless hum against his lips before the pixie was speeding up, pulling back onto his knees. He came moments later, mouth parted in a silent cry, chest heaving as he spilt onto the tanned skin of his stomach. The raven head was faintly aware of Jimin pulling back, saltwater being scooped onto his stomach, tender hands washing his skin.
“You okay?” He forced himself to open his eyes, squinting up at the blond figure stood over him, gaze fuzzy in his post-orgasmic haze.
“Mhm… Feel good, hyung.” The words came out all soft and breathless, sated, just like how the merman felt. Since he got no response, the younger busied himself with tracing his gaze over Jimin's figure, blond hair illuminated like a halo by the sun behind him. Oh. “You didn't come.” The raven head felt his brows crease at the revelation, spent cock giving a little twitch at the sight of the pixie's, still hard and curved up against his stomach, the tip a pretty pink.
“So? You already have, Jungkook-ah. I'm not going to force you to go again. Even though we hate each other, I'd never be that mean.” Despite the soft words, the merman's brows remained creased.
“So you're not gonna let me help?” He scoffed. Jimin's expression hardened almost immediately.
“Not with that attitude, no.” The younger felt the urge to retort, to say something bratty, but he held the urge back.
“Fine. Please..? Hyung?” Jungkook cocked his brow, putting on what he hoped was a sexy expression. It must've worked because not even a moment later there's a strong hand curling into his dark locks and then he'd being tugged up, a dull ache blooming in his skull at the sudden action.
“You want to help? You're that desperate for your hyung that you've resorted to begging?” If he hadn't been so orgasm-drunk in that moment he would've fought back, but instead, all the raven head could muster was a mildly put-out look.
“Fine. Forget I offered.” The younger responded snarkily, turning his head away, watching as his scales began to grow back, the water lapping gently at his tail.
“Nuh, uh, none of that brattiness. You offered to help, so you're going to help. You understand that?” The merman gazed, wide-eyed at the soft touch of a thumb against his bottom lip, “Come on. Tongue out, Jungkook-ah.” He poked just the tip of tongue out, eyes defiant as he watched Jimin's jaw tick as the blond stepped closer, fisting his steadily-leaking cock. The elder raised an eyebrow at the defiant look, abs tensing as he pressed his tip against Jungkook's lips, sucking in a sharp breath as he pushed his hips forward.
“Hngh-” The raven head's words came out muffled around the pixie's cock, jaw aching as his nose was suddenly pressed against warm skin, throat closing around the thick length, head swimming with the lack of oxygen. He'd only just gotten used to the sensation before Jimin was pulling back, heaving breaths leaving the younger's lips.
“This okay? Jungkook-ah? I'm going to fuck your throat, alright? You can squeeze my thigh if you need to tap out.” Jungkook was in no way going to tap out. He was already missing that blissful, hazy state, a low keening noise building in the back of his throat as his empty hands curled into fists on his scale-covered lap. The fingers threaded tighter into his damp hair and then the elder was pressing forward once more. Over and over. The merman willed his tensed jaw to relax as he swallowed repeatedly around the blond's leaking tip, tears overspilling as he was only granted relief once he'd begun to space out, eyelids drooping.
“Ngh- Hngh-” His choked words drew nothing except a gentle croon from Jimin who had begun to pump his hips, cradling the back of Jungkook's head as he drooled around the elder's cock, eyes fluttering shut, Adam's apple bobbing at the repeated jabs to the back of his throat.
“Shit- Jungkook-ah, I'm going to-” The younger's eyes were forced wide, teary and star-struck at the sudden gush of come flooding his throat. He gurgled, brows furrowed as the pixie pulled back, gentle fingers carding through his hair as he doubled over, chest heaving, “Good boy. Fuck. You're okay. Hyung's sorry he didn't warn you. Shit. Felt so good, Jungkook-ah.”
🐚🐚🐚
Jungkook swore that leaving him had almost become a habit of the pixie's. This was the second time he'd been left on a beach and he swore it was going to be the last.
It was early evening by the time the merman had shed his tail once more. He'd spent the rest of the day, after being so thoroughly fucked and used by Jimin, basking in the sun and muttering half-assed insults into the gentle wind. Now, he stumbled up the cove towards the forest that took up the majority of the island, lips jutting out in a petulant expression as he tried to remember where the elder's cave lay. He finally found it, ducking into the entrance just beyond the line of trees and pushing open the wooden door wedged into an opening a little further in.
“Hyung..? Jimin-ah?” The raven head picked his way over the loose sea glass scattered over the stone, peering into every empty adjacent cave he came across. At last, the tunnel led into a large open cavern, which seemed to be the one that the pixie lived in. A turquoise pool made up most of the floor, a haphazardly-made bed pushed up against one wall and a cooking area against another.
“What the fuck are you doing in my cave, Jungkook-ah?” Jungkook blinked at the sudden harsh voice, wide eyes zeroing in on the figure bobbing about in the middle of the pool.
“Well, I- uh- I lost my way?” Good one, Jungkook. How incredibly believable. The scoff he got in return was expected.
“You're twenty-four years of age, Jungkook-ah. You've swum around in these waters more times than I can count, and explored this island even more than that. Do you really expect me to believe that you lost your way?”
“Y- yes..?” There was a gentle splashing as the blond swam up to the edge of the pool, a shiny hand beckoning the merman closer. Closer and closer. He crouched down, swallowing thickly at the way the water run down Jimin's forehead, hair now a dusty brown, slicked back, eyes unforgiving. And then suddenly he was underwater. The younger thrashed around, kicking his way to the surface, strong arms latching onto the pixie immediately, “Fuck! Are you trying to drown me?! I can't swim with legs, hyung- I told you-”
“Shit- calm down. I've got you. I know you can't swim without your tail.” Slender arms secured around his waist, and despite his words, the elder's tone sounded slightly sheepish. It took a while for the raven head's breathing to return to normal, but when it did, he finally braved lifting his head from where he'd promptly hid it in Jimin's neck. The sight that greeted him almost stopped him short. They were close. Way too close. Noses almost touching, the blond's eyes staring steadfast into his.
“Hyung?” Lips against his was the only response he got. They kissed endlessly, roughly, panting into each other's mouths, hands touching any bare skin within reach beneath the water.
“Fuck. You piss me off so much, Jungkook-ah.” Jungkook didn't really know how he was pissing the pixie off by allowing him to shove his tongue down his throat, but he was too blissed out to care about the semantics, responding only with a small hum, “I mean it, Jungkook-ah. We hate each other, remember? You annoy me and I annoy you back. None of this fucking around nonsense fits into that dynamic.” A drawn out whine slips from the merman's lips before he can stop it at the sudden loss of the blond's lips.
“So? Can't we fuck around and hate each other at the same time?” Who was he kidding? Jungkook didn't have the capacity to hate Jimin anymore.
“No, Jungkook-ah. We fucking can't. This needs to stop. I shouldn't have given in.” The raven head feels protests swimming around in his head as he's gently pushed away, the pixie stepping out of the water, slim body on full display as the younger sinks onto the pool's natural steps, fighting the urge to sulk. That fucking pixie-
