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.*

[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.*

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?

[A heat rushes to Gon's cheeks as Killua braces him in place. He sniffs Gon and Gon's arousal slowly returns, somewhat dampened. Gon shakes his head at his question.]

Yes, please! Warm me up.

[Fingers preemptively weave themselves into Killua's silver poof.]

*encouraged by gon's receptive touch, killua makes a show of sucking in a big breath of air before ducking underwater again so his face is between gon's thighs. he decides this would work best if he had full access to gon's lower half and reaches around to tug his shorts down along with his boxers, bunching them around his knees. once his cock is floating out in the open water, killua blows his held breath out in a volley of tickling bubbles against his bare skin to stimulate him further, then begins breathing water through his gills, planning not to resurface until he's given gon an orgasm to remember.*
