mermaid room (nsfw)

*when gon beckons killua into the aquarium room he's just found, killua expects to be able to walk up to the glass and watch the fish with him, not be teleported to the other side of it. his heart jolts into high gear as he thrashes about, knowing he didn't take a proper breath to hold before he found himself deep underwater. he tries to kick his feet to bring himself to the surface high above, but his legs seem to be bound together, and when he looks down, eyes wide with mortal panic, he realizes why.

they've been replaced with a long, glittering, fish tail.

the air he'd been desperately holding in his lungs escapes in a rush of bubbles from a couple of frilled vents along his ribs, and as he draws in a gasp of surprise, the water glides into them, bringing oxygen back to his brain. able to think clearly again, he blinks in wonder at the strange new appendage and manages to use it to push himself through the water and meet gon at the glass, holding his hand up to his through the barrier.*

hmph.

*killua lashes his tail again, but makes his way over to gon, resting his upper body on the rock formation beside him. his tail spreads out behind him, its frilly dorsal fun rising above the surface. the lights above the tank shine down on his scales, making them glitter as it sways slowly up and down in the water.*

[Gon leans on the same rock and kisses Killua on the cheek.] You're kinda cute when you're all moody.

[He looks behind Killua at his outstretched tail when a glimmering scale catches his eye. He wants to touch it still, in awe of its luminescence. Gon reaches down and smooths his hand over Killua's exposed scales. They're smooth beneath his fingertips like he expects them to be.]

Do you mind being touched like this? It doesn't hurt or anything, does it?

*killua grumbles, flushing deeper as he's kissed. yes, he's moping, but he wouldn't be if gon had caught him in a more dignified position! he'd been literally caught off-guard, and now he's back to feeling awkward in his new body. but he can't deny that gon's palm running over his scales feels nice.*

no, it's fine. it's just like you're touching my side.

That's so weird! I wonder if the room would turn me into a mermaid if I asked nicely..I'm way too curious! [He affectionately pets Killua, stimming on the light texture of his tail and watching it glimmer in the tank lights.] Wait, I'm curious about something! Do your fingers still get all wrinkly when you're a mermaid? I've been in the water for a long time and mine are..

*killua's eyelids droop like a pleased cat's as gon continues to stroke his tail, flicking his fin in idle enjoyment. when he asks about his fingers, he looks down at his own and then rolls onto his back, holding them out to gon with a grin.*

nope, perfectly smooth.

Wow, I wonder why mine get wrinkly?

[He touches Killua's fingers to his own, giggling.] Mine look like little brains, hehe! [His hands return to Killua's tail, stroking him on the front this time, with ten ridged fingertips. He uses broad motions, amused that he's petting his fish boyfriend like a big dog. The type of absurd situations this ship put him in almost always put a smile on his face. If his dad was responsible for this ship, he was really thankful.

While he's rubbing him down, Gon's hand passes over a spot with a different texture and he focuses it there, rubbing in tight circles to get to know the area. It doesn’t occur to him where his hand is or that there's a slit there.]

Hmm..what's this?

*killua giggles too, spreading his fingers and bragging:*

mine adapted.

*he lays back on the rocks with his arms crossed behind his head, closing his eyes while he quietly enjoys the attention from gon. he'd never admit it of course, but he really does love when he's being all tender like this. after being starved from affectionate touch for so long, killua can't help but soak it up every chance he's gotten since arriving on the airship.

he notes as gon rubs his hands over him that his belly scales are more sensitive than the ones on his back and sides, smaller and closer together, giving them a smooth, almost velvety feel. gon must have just discovered this, as his fingers start to focus on the most sensitive spot, somewhere between his hips. with his legs gone, he doesn't realize just where he's touching until he feels his fingers slip into a dip between his scales, breaching the warm flesh within. his hips jerk in surprise and he jolts upright, bracing himself on the rocks with a gasp.*

gon!

*he gulps, heart racing as he stares down at his lap. he thought before that he didn't have genitalia in this form, and he still can't see anything but a slight dent in the front of his tail, but it sure felt like gon had just touched his groin.*

i think... that's my...

*he suddenly shoots out a hand to grab gon's and stop him from going any further before he's had a chance to figure this out.*

w-what do fish have down there?

Huh! I wonder what other adaptations you've made.

[Killua's reaction to the touch startles Gon and his hand freezes up.

"I think... that's my..." Suddenly, Gon's cheeks heat up and he feels very silly for playing so recklessly with Killua's body. He looks up at Killua shyly.]

Your vent...I, um. I think? It's where the eggs and sperm come out, as well as water and waste. It's kind of like a human's...well, you know.

[A thick blush heats his cheeks but he's not deterred, even more curious about his boyfriend's new body now.]

What does it feel like? Being touched there, I mean?

*slowly killua relaxes his grip, letting gon's hand go as he processes this new development.*

so... it's just a slit? like a girl?

*he grimaces, totally weirded out by the idea of having just one hole for everything. his ear-fins pull shyly back, face still flushed from the shock of gon's fingers slipping inside.*

it's... really sensitive. but not in the same way as the gills...

*gon's fingers in his gills had felt like an uncomfortable intrusion, like something being shoved down in his throat. but the feeling of them pressing into his slit was pleasurable in a way he can't quite explain, unlike anything he's ever felt in his experimentations just touching his dick.*

[Gon's amused at his facial expressions, wondering just what kind he himself would be making if he had just found out he had a girl's parts. He supposes he wouldn't be that bothered. Maybe it'd be fun!

He was thrilled to hear how sensitive it was. Gon decides to make the most of Killua's new and unique body, running his fingers up and down the entrance of his slit before dipping one in. The scaled part opens up to a warmer, fleshier opening that's slick on the inside. He experiments, wiggling his finger against Killua's walls.]

*killua's fingers curl against the rock as gon teases the inside of his slit, drawing out sharp gasps that make his gills flutter on his sides. each movement of his fingers brings a little shock of pleasure that drives deep into his core as gon delves into it. if he'd still had his usual arrangement, he'd definitely be hard by now -- and sure enough, as gon presses deeper, something pushes back against his fingers, swelling with each pulse. killua gulps, feeling almost nauseous from the combination of confusion and stimulation.*

a-ah... something's... coming out...

[Gon pushes his fingers deeper only to be blocked by something on its way out. Humming in interest, Gon lifts his hand and lets the new appendage fully extend out of his slit.]

Woah, fish don't have these! It must be a mermaid thing..

[He wraps his hand around the pink tentacle-like appendage, pumping it up and down.]

Your new body's full of surprises, isn't it?

*killua makes a disgusted warble in his throat as his transformed cock unsheathes, tensing up in fear of his own alien body. he feels even more sick at the sight of it curling around gon's hand as if it were one of the tentacles that molested him, covering his mouth in horror.*

w-why does it look like that...

*he turns his head away so he doesn't have to see what's become of his privates, leaning into gon's side and panting against his shoulder in labored huffs. despite how unfamiliar it looks, the feeling is unmistakably the same as all the other times gon has pumped his cock, agonizing and overwhelming and wonderful.*

Edited 2023-03-27 18:53 (UTC)

Woahh, it's got a mind of its own!

[Gon is amazed by it, letting the shiny, wet mass curl and flick against his hand. He'd never seen anything like it before. At least, not small and pink on the boy he likes. It wasn't threatening at all like the tentacles used to molest them. In fact, he thought it was..]

...Cute.

[He turns his head to kiss Killua, his cock squelching in both of their ears.]

it's weird--

*killua is cut off by gon pressing their lips together, momentarily melting his worries away. his prehensile cock continues to lap at gon's fingers like a tongue, secreting plenty of mucus to keep them gliding smoothly over its pulsating surface. as long as he keeps his mind off the specifics, it does feel pretty good. he throws his arms around gon's neck, distracting himself with making out while gon takes care of the mess he's made below.*

Mmm..

[Gon's hand slides effortlessly up and down the throbbing muscle, the mucus spreading on his hand and squelching noisily as he speeds up his arm. Gon smiles into the kiss before sliding his tongue over Killua's bottom lip, inviting himself inside his mouth.]

*the kissing distracts killua so thoroughly that he doesn't realize how far he's built up until he's almost there and an involuntarily jerk of his hips snaps him back to reality. breaking contact with gon's mouth, he mumbles:*

mmmn- i'm close. can this thing even...?

*he gets his answer a moment later when the squirming organ stiffens in gon's fist, spurting out much more liquid than a human could and splattering them both with watery spend. killua gives a strangled yowl, thrashing like a caught fish on the rocks in a combination of mortification and ecstasy.*

[Gon is amazed by the sheer amount of milky, white ejaculate on his hand. Without thinking, he lifts his hand to his lips and darts his tongue out to sample the fluid. When it touches his tongue, his nose immediately wrinkles at the overwhelmingly bitter, salty taste.]

Eugh! Dunno what I expected, to be honest..

[He giggles sheepishly.]

*in the wake of his violent orgasm, killua clings to gon's side, shuddering with both aftershocks and disgust.*

nngaah. that's. gross.

*he takes a peek down at the mess on his lap to find the tentacle of his cock now lying limp amongst his cum-splattered scales, a sight so repulsive he nearly gags. feeling too boneless to keep himself upright any longer, he slips fully underneath the water, letting it rinse him clean.*

Nothing about you is gross. It just tastes that way!

[He watches Killua retreat into the water and dips his hand in it, swishing it around so all the spend floats off in the water. Then he climbs back into the deep part, following Killua.]

You really don't like that body, huh? It's a shame, because I do.

*killua shrugs, drifting lazily around gon as his body tingles all over from his orgasm.*

the tail's alright. but i could do without the tentacle dick.

*luckily, said organ seems to be retreating now, receding back into his slit as the cool water lowers his body temperature.*

I thought it was cool. I wonder what sucking it would be like..

[He says casually, always having Killua's body on the mind. He watches the organ retract, still amazed by it. He wished his did that! But, well, Killua would be repulsed if his were like that. He smiles sheepishly at the thought as he swims in sync with Killua.]

What should we do now? [He touches his fingers.] I'm super wrinkly.

*killua flushes, the still-protruding tip of his cock giving an interested little twitch at gon's musing. he brushes a hand over it to shoo it away, but the arousal in his belly doesn't fade.*

actually, i was thinking...

*he backs gon up to the rocks again with a dubious, fanged grin.*

i should return the favor.

[Gently pushed back by Killua's advances, Gon allows himself to be guided until his butt meets solid rock. The look on Killua's face makes him inhale in anticipation.]

G-go ahead..

[He undoes the button and zipper of his wet shorts, opening them up to his boxers. Underneath them he's soft from the cold water.]

*after bracketing gon against the rocks with a hand on either side of his waist, killua dips down to sniff at his exposed boxers, enhanced senses drinking in the scent that's been clouding his head ever since he'd had his face pressed into gon's shorts. he surfaces up to his neck again after, the gills on his ribs pushing out a flurry of bubbles beneath the water.*

when we were kissing, i started wondering if i'd be able to do it underwater without coming up for air.

*he tugs coyly at the band of gon's boxers with a sharp claw.*

mind if i test that theory?
