Rubbing the sleep from his eyes, Gumball stumbles out the bedroom door. It's still dark out, likely far past midnight, but his eyes were too blurry to check the clock. All he knows is that he has to pee.
On a normal night, he might have been able to sleep through it, and wait until morning, but he had been having a bit of a hard time sleeping lately to begin with. It really wasn't the same without his best bro sleeping beside his bed. Not like he couldn't just see Darwin in the morning, but it still took a bit of adjusting, after everything that had happened in the past week.
With his palm on the wall, sleepily trudging down the hallway, Gumball's mind wanders. He recalls the events that led to Darwin's too-small fishbowl breaking. He remembers waking up that morning, just last weekend; Darwin was on his hands and knees on the floor, surrounded in a small puddle and shards of glass. He was as shocked as his two siblings were, as he stared down at his new body.
That morning, the goldfish's knack for breaking the laws of nature was somehow triggered again, and he spontaneously grew a torso. Nicole guessed it could have been puberty that spurred it on. Either way, it was definitely something the boy had to adapt to. He was stumbling around a lot that whole weekend, and itching at the clothes he felt the sudden pressure to wear. From then on, he couldn't exactly get away with walking around with only shoes on.
Gumball remembers not having the time to get a good look at Darwin's body, before he had to cover up with some of his extra clothes. At least until they stopped by the mall to buy him some better fitting ones. Since then, Darwin had been wearing a green, oversized hoodie, and simple shorts. It fit his personality well, the baggy silhouette and extra long sleeves showcasing his cute, playful youth. Gumball couldn't help but feel a little curious though, especially every time he caught a glimpse of a scaly abdomen when Darwin raised his arms. He wasn't the only one. Everyone at school in the following week was just as fascinated with his growth spurt. The boy had been getting a lot of attention for it. He seemed to enjoy it too, judging by the way the blubbery, vibrant fish tail at the base of his spine wagged. The way the light caught the translucent tailfin at the end of it made Gumball feel a weird urge to pounce on it. Its movements reminded him of a cat's toy. But he'd never admit that. That would be too weird!
Gumball shakes his head, clearing the flashback from his mind. He has no idea how long he had been just sitting there outside the bathroom door, and his bladder’s starting to complain. He opens the door and flicks on the light, completely forgetting that he would be disturbing the sleeping fish in the tub.
"Dude..." A mildly annoyed, half asleep mumble comes from the tub. The shower curtain is closed. With a start, Gumball remembers that's where Darwin's been crashing, at least until their mom can afford to get him a bigger tank. He could, in theory, just sleep in a bed, too, but it isn't very good for him. When he's not awake, his brain favors his gills over his lungs, so he would constantly be coughing himself awake if he forgets to breathe. A simple fix is to let him sleep underwater.
"Shoot-- Sorry. I just gotta pee, I'll be quick," The kitten apologizes, as he sheepishly makes his way to the toilet. This time, he's careful not to make too much noise as he lifts the lid.
"M'kay..." Darwin's response sounds like he's back to sleep already. Gumball realizes the curtain isn't all the way closed, and he can see around the corner of it from where he stands. He notices the orange body floating peacefully in the water. Completely nude, because no one had thought to get him a pair of swim trunks to sleep in yet. Shadows cast over his relatively featureless body, his smooth chest sporting no nipples as a mammal might have. No belly button either, but glimmering, fresh scales, coating every inch of his body in uniform, neat lines. Most of them are the same color, except a few that slightly differ in hue running down his sides, hips, and thighs.
Gumball's eyes follow the subtle patterns down his body, lingering on his crotch. There isn't anything there, like he was subconsciously expecting. From this angle, it looks as smooth as a mannequin’s. Gumball doesn't even realize how much he was staring, or how inappropriate it was to be. He was too sleepy to catch himself, not until he blurts out a question in the same instant it occurs in his head.
"Are you a girl?"
His voice crashes through the silence, startling them both.
Darwin's eyes open.
"...What?!"
"You.. Uh..." The kitten can't find the words to elaborate with.
"You must've had a weird dream or something... Just go back to bed," the fish sits up enough to close the curtain the rest of the way, obscuring the other's view. The water gently sloshes in the tub as he does.
"Okay," is all Gumball could really say. He feels dumb, and a little insane for randomly asking something like that, especially in the midst of peeing. How awkward! He quickly finishes up, washes his hands, and returns to his room.
The following school day wasn't anything special, but it was at least distracting enough to keep Gumball's hyperactive mind occupied. He had pretty much completely forgotten about what happened the night before, after he allowed himself a moment to cringe at his question when he woke up that morning. Darwin never brought it up, so he concluded that they could happily move past it.
The boys find their way back home in the afternoon. They are in the midst of some meaningless, pedantic argument that seems to be entertaining the both of them well enough. It started with some random conversation about houses, comparing their friends' homes to their own. It evolved to the two suddenly remembering they had a basem*nt that they keep forgetting about for some reason.
"No-- I'll prove it to you! The basem*nt is DEFINITELY bigger than our room," Darwin challenges. "Maybe even big enough for a pool!" His addition is clearly only wishful thinking. The poor boy probably wants his own place to sleep again, especially one where he can sleep in without getting woken up every time someone has to use the bathroom...
They make a bee-line for the entrance to the cellar, not even taking the time to drop off their bags upstairs first. They'd definitely get scolded later for dumping them at the front door, but that's not on their minds right now. Gumball leads, carefully toeing the edges of the staircase down while he blindly feels for a light switch. He finally finds one, illuminating a single, bare bulb hanging from the unfinished ceiling. Darwin gives out a little cough, the dust already getting in his gills. The basem*nt has loads of boxes strewn about, filled with forgotten toys, old books, holiday decorations. But the room was indeed a bit larger than Gumball remembered.
"...Okay, well, it just looks bigger because there's a lot of stuff in it. It's like... An illusion!" Gumball scoffs, utilizing his uncanny skill for instantly convincing himself of anything, no matter how unrealistic, as long as it protects his ego.
"I don't think that's how it works..." Darwin trails off, too distracted by the mountains of junk to finish the argument. "Oh! This old mattress is still down here."
Squeezing past a few stacks of boxes, the fish grabs the double sized mattress by the edge and starts to shimmy it out from where it leaned against the wall. Once it's free, he takes a step back, barely dodging it as it falls to the concrete floor with a thud. The resulting cloud of dust throws both boys into a coughing fit.
"Ew, there's a big stain on it! Don't touch it," the kitten recoils, but immediately leans forward again to observe it closer.
"I already did, it's probably old... It's fine, I can put this on it!" Darwin pulls off some random tarp from the pile it was draped over. He drags it over the mattress, and jumps onto it to pin it in place. The corners of it swish upwards, as he slightly bounces. The old, creaky springs inside the mattress complain under him.
"You think that's good enough? There could be bugs crawling on there." Gumball steps closer, his curiosity still getting the best of him. But Darwin doesn't seem too worried. He stands over him, slowly lifting his paws as a fun little impulse springs up in his mind. "In fact I think I see one! Right... There!" he lunges forward, and shoves his hands up under Darwin's arms.
The fish, gullible as ever, had been too busy checking his surroundings for bugs, leaving himself vulnerable to the tickle attack. His outcry turns into giggles, squirming fingers intruding his armpits as he tries to scramble away. His brother doesn't let him, crawling forward and keeping up his tickling until Darwin is flat on his back. He swats at Gumball's face with his floppy sleeves, his face all twisted up in laughter as he keeps trying to escape.
"Hahaha- Stuh- Stop! Okay, okay okay!" he gasps out, pushing back on the kitten's chest as he continues to giggle. If Gumball thought he was putting up a fight now, he would be surprised to see how much more he squirms when his tickling starts to trail down his sides, towards his stomach. The boy's eyes widen, and he jolts, like he wasn't expecting it to tickle quite thatmuch.
"Oh yeah... I guess you never had a belly to tickle before, huh?" Gumball thinks out loud. He grabs a fistful of Darwin's hoodie, and pulls it up a few inches, his devious smile and slit pupils shining down on his brother's confused face. Paws creep closer to the exposed midriff. "Guess what? They're suuuuuuper ticklish!"
The resulting scream-laugh is exactly what Gumball wants to hear. Just as he expected, Darwin had nothing else in his life to compare to how sensitive his belly is! He's thrashing around so violently, his fish tail slapping at the tarp below him, that he almost looks like a salmon that had just been caught out of a stream. And Gumball is having a hard time not getting bucked off, or worse, kneed in the groin.
He quickly has to amp up his efforts to keep the goldfish still enough, to feel like he won their little playfight. With a bit of struggle, he manages to pin him down, with a knee on his stomach and a grip on one of his wrists. The free hand slows its efforts to push Gumball away as the younger brother tires. The winner gives a cheeky grin and sticks his tongue out, playfully blowing a raspberry in his face.
"Oh no, the bugs got me!" Darwin catches his breath enough to speak, his giggling dying down. His hood had fallen off his head in the tussle, revealing a dorsal fin fanning out from the back of his head, tapering down and stopping at his neck. He props himself up on an elbow with his free arm. "You can get off me now."
"Right!" Gumball starts to oblige, first by releasing his wrist. He sits up straight, straddling one of his legs, but something stops him before he stands. He ignores the inquisitive gaze on him, fixated on the exposed tummy he had just been attacking with pokes and prods. He reaches down to touch it again, this time out of gentle interest. Darwin flinches at first, but upon realizing it wasn't time to be tickled again, he doesn't move much more. Even when his sweatshirt is pushed all the way up, and held there, keeping his chest exposed. His eyes bounce from the paw on him to Gumball's face, looking for an explanation.
"What're you doing?"
"..." It takes Gumball a while to answer. The question seems to fail to reach his ears, until he finally glances back up to Darwin's face, and notices he's being stared at. "Oh, uh, I was just checking something."
"Checking what?" Darwin snickers as he presses further.
"Well, you look really different now... So I'm just curious?" The kitten shrugs. "It's kinda cool how smooth and shiny you are all over. Like if you gave a tangerine a botox treatment."
The paw moves down again, brushing over his sternum as he makes zigzag lines tracing between scales. There isn't any voice speaking up to tell him to stop, so he keeps going, for a bit. After the third time of trying to scrunch the hoodie back up, fighting against it sliding back down, he starts tugging it with more frustration. If he was going to keep exploring these anatomical curiosities, the sweatshirt would have to go.
"Can you take this off?"
Darwin's brows crease, but he starts to sit up like he's going to undress anyway. "...It's kinda weird if it's only me doing it."
"Okay, fine," before even getting a chance to think about it, the beige sweater flies in some random direction, getting lost in a junk pile behind Gumball. "There! Now it's not weird."
Darwin blinks. "Okay, but it's not like you haven't been naked in front of me before. Or the entire town, for that matter," he comments, and plays along anyway, following his example. Gumball scoots back, giving him room to sit cross legged and parallel to him. The fish is mirroring all of his brother's movements, putting his hands on his shoulders and chest in the same way he is. Gumball isn't really sure why, but he's assuming he's making a game out of it in an effort not to feel left out.
Gumball isn't always one to focus on the details, but something about the moment had him easily zoned out as he studied his body. Without any resistance on the other's end, the kitten grabs one of the hands resting on his knee. He holds out the wrist in front of him, rotating it gently, curiously. His hands, usually covered by large sleeves, are much more complex than they used to be. He parts two of Darwin's fingers, to discover thin webbing between them.
"Woah...! You think this makes you swim faster?" There's amazement in his voice.
"I 'unno. I haven't tried it yet," Darwin responds, with a slight shrug. Gumball is too concentrated on his hand to pick up on the difference in his tone, how he sounds a little shier now.
His eyes drift back up Darwin's arm, and his paw follows, testing to see if it feels different to pet the scales the wrong way. It barely does. He stops at the base of his neck, noticing his gills. They stand out a lot more than they used to on his new neck. He pokes at the very corner of one, ignoring an intrusive thought to try and jam a finger inside. That'd probably hurt.
He's shaken out of his thoughts when he sees the fish flinching a little. He looks up to his face, worried that he had accidentally pressed too hard. He was sure he wasn't putting any pressure at all, so what did he do? He sees his brother staring right at him. His lip is jutting out into a small pout, and his cheeks look warm.
"Sorry! What's up?"
“Nothin’, I’m good… Just a little sensitive there,” he fidgets.
“Okay… Not too weird yet?”
“Eh, that ship has sailed. Don’t worry about that.” Darwin has a point.
"So," feeling a surge of confidence, Gumball mulls over how to say something. It's been burning in the deepest corner of his brain for the whole day and it seems like now's the only time he could bring it up again.
"Okay, this might sound bad but... Why don't you have... You know." He seeks out a spark of recognition on Darwin's waiting face, only to get none. He clears his throat. "Why don't you have nuts?"
A signature awkward grin spreads across Gumball's face. The fish glances down at his own lap, as if he's suddenly realizing that must have meant the other was staring at it at some point. The good part is, he doesn't seem offended, just amused.
"Well, have you ever seen a fish with nuts?"
"Okay, good point!" The funny mental image it prompted almost throws him off track. "...So then is there like, completely nothing down there, or..."
"Uh, no, there's... Here, lemme just show you!"
Before Gumball knows it, the other is up on his feet, already pushing off his shorts. The motion would have been fluid, if it hadn't caught on his sneakers that he still wore. He's now reduced to the exact amount of coverage he had been used to for the majority of his life, which must be why he seems rather nonchalant about it.
"Oh--" the kitten flinches, ready to avert his gaze, but he can't keep from staring at what's right in front of him. From his experience, which consisted only of looking at pictures on the internet (an absurd amount, to be fair), the only thing he could assume it to be was a puss*. A perfectly thin, almost invisible slit, so subtle that it would not even show from most angles. A key difference is the apparent lack of other orifices in the same area. There's only the one.
Darwin stands there, his legs somewhat apart and his tail dropped between them. His hands are planted at his sides, like he has no idea what else to do with them.
"If you don't have anything that sticks out, how are you not a girl?" It's Gumball's genuine question, if a little insensitive.
"Is this what last night was about?!"
"Uhh, I-I mean–"
"Besides! Yours doesn't stick out either."
"Yeah, not all the time! It does though! You can easily tell if you--" Wait, when did hispants come off? Where did they even go? Now he's standing too, his paw pressed down on his stomach as he peers down. Careful not to scratch himself, he guides the tip of a finger over his sheath. It ever so slightly protrudes from him, his short fur doing no help in keeping it, or the tight, fuzzy balls underneath, obscured. The sheath is teased open, allowing a glimpse at the tip of the tapered dick it encases. "See? It just comes out from here."
Darwin has a similar impulse to flinch and look away, before remembering he was supposed to actually watch this time.
"Yeah, okay I believe you! You didn't have to show me," he offers, but the way he trailed off, and kept staring made it seem like his own curiosity was also getting to him. He even goes so far as to cup the whole package in his palm, to tilt it up and get a better view. Gumball's breath hitches.
"Hey, what the--" he half-laughs, as he was clearly not expecting to get groped like that so suddenly. But he doesn't pull away. As the both of them stare down at his groin, an inkling of anxiety in the back of his head makes him wonder if he'll accidentally start getting hard. There’d be no way to hide it. That would be… Bad, probably?
"Does yours come out too, then?"
"Yeah. I'm... Pretty sure."
"What do you mean you're 'pretty sure'?"
"Well... I didn't see it on this new body yet. It's-- It's only been a week! I was too scared to check!"
The kitten is maybe a bit more eager than he should be to find out for himself. He only has to frame it as a favor to Darwin first. "Wait-- seriously? Good thing you have me then, I'll just check for you!" He ushers the fish back down, who sits back and slowly parts his knees.
Any hesitation he might have had before, was chipped away by the series of events leading up to this. To the very moment he puts his fingers right on him, leaning forward to watch closely as he delicately parts the slit.
His eyes get big. He presses down a little harder, convincing the other to tilt his hips up to grant a better angle. His second paw joins the first, barely poking the tip of a finger in without truly pushing it inside. "Ooh, I think I see--"
"--Wait, this is basically what happens before people have sex, right?"
"Huh?" Gumball blinks. His train of thought derails, completely swept away and replaced with blank, as he attempts to make sense of the words said. He swallows audibly. He can't help but laugh away his embarrassment, which is returned, likely for the same reason. "I, heh-- I guess so... But aren't you supposed to do other stuff first? Like... Before that?"
"Like what? ...French kissing?" Darwin replies, his eyes looking for something off to the side as he thinks.
"You ever done that before?"
"Nope. You?"
"No... I don't think Penny would let me do that any time soon..." The kitten trails off, not continuing until he can catch eye contact again. His paws return to his own lap, and he sits up straighter. He whispers, a little giddy, "Wanna try it?"
The younger boy rises to sit on his knees, almost before the question is even finished. The both of them take a deep breath and face each other. Both place their hands on the other's shoulders, just like they were doing a bit earlier. They take a moment to calculate their next moves, trying to see if they can figure out who's planning on making the first. Nervous glances to each other's mouths. It's not like it's the first time they've kissed or anything, so that part won't be too hard, but what happens past that? Where are you even supposed to put your tongue?
"Do I just..." mumbles Darwin, who is the first to close the distance, letting some burst of jittery impulse carry him forward. The first contact is a quick, testing peck. The second kiss is longer, smoother, now accounting for Gumball's snout by tilting his head. All they have to do now is open their mouths. Gumball feels a warm breath over his face, and he's about to ask if he doesn't want to try after all, but can't. Instead, he feels a tongue poke his lip, and the kiss suddenly deepens.
It doesn't feel real. He goes along with the motions, silently thankful that it wasn't him who had to take initiative, or else he might have chickened out. He sighs out through his nose, his screwed-shut eyes relaxing as he untenses. He feels the hands on his shoulders squeeze, pulling him in until their chests are almost touching. How many seconds has it been? When is he supposed to pull away? A spot of drool dribbles from the corner of his mouth, as inexperienced tongues flick against each other, their teeth almost clacking together. He's so caught up in his own head with questions that he doesn't realize that the subtle vibrations he can feel in his mouth are mostly coming from him. He's purring. It's hardly audible, but he's certain that Darwin noticed.
Maybe it's the embarrassment from that, or maybe it's just to catch his breath, but Gumball finally pulls away, and he shifts around in his seat, looking for a comfortable position. His paw brushes against something wet on its way down to the floor between them. His eyes fly open.
He first sees Darwin's face, glowing hot and his expression looking practically drunk. His glazed over eyes aren't focusing on anything until he feels a teasing finger poke at something he wasn't so sure he even had, until this moment. He jolts, earning a giggle from the kitten.
"Found it!" Gumball grins, and he can't help but act smug. Was it just from the kissing that made it get hard like that? He can't tell how hard it's supposed to be, from how different it looks from his own. He doesn't want to think about how obviously larger it is than he expected. It resembles a tentacle, not standing up straight so much as it leans on Darwin's thigh. The whole thing is slick with pre that must have been collecting since before it slid out to greet the world. It reacts to Gumball's gaze with a needy twitch.
Two blue fingers press on the underside of it, as if checking for a pulse. They inch further down towards its base, slow enough to give the fish ample time to object. But he doesn't, he holds as still as he can, eyes locked downwards, anticipating each second. Though Gumball isn't paying much attention to him, nor does it occur to him, yet, how this might feel. His intention isn't to be teasing, he's truly just exploring.
"There's a bunch of space right behind it," the kitten notes out loud, tracing the edges of the cloaca as even more questions pop up. He might as well ask them, with the way this afternoon is going. "Do you think it'd feel good if you put a finger in it?"
"Sounds like it'd hurt," Darwin mutters.
"But it's pretty wet, so if I went slowly, it probably wouldn't, right?" He's already volunteering himself to attempt it, and his pokes are gradually increasing in pressure until the first half-inch is intruding. He hears a tiny gasp. "What if it feels awesome instead?"
Snirking at the word choice, or maybe the whole situation, Darwin leans back again. He props himself up on his elbows. "Okay, do it."
Gumball doesn't know what he expected, but after easing the rest of his finger inside at a careful, glacial pace, he doesn't know how to describe it. It resembles the wet squishiness of a mouth, but the tight squeezing around his digit, and the resulting squirming, and strange faces that Darwin was pulling, makes it a much different experience. He can still feel the hidden base of the swollen shaft from inside, and the excitement drumming through it.
"What's it feel like?"
"It's.... Weird. Good weird," the boy is quick to clarify, even if he sort of looks like he's in pain. He lets out his held breath as soon as the finger moves again, gently sliding out and back down to the knuckle. By the time a second is added, it feels extra tight, almost like a third wouldn't even be possible. As tight as it is, it still leaves Gumball wondering, in his increasingly perverse head, if it might be able to take something else.
"So it doesn't hurt?"
"Mmh- no," he strains out, and drops flat on his back, like his arms don't want to hold him up any longer. His soft, out-of-focus gaze through his lashes, and his quivering lip are really cute. In a much different kind of cute than Gumball was used to seeing him as. He pulls his paw away, watching the thread of fluid connecting it to his brother's slit. Some wires are definitely getting crossed in his brain, and he doesn't have the capacity to tell if that's a bad thing yet. He swallows dryly.
It's impossible for Gumball to ignore his own reactions the longer he plays with Darwin like this. Looking down from where he sits, with his knees propping the other's legs open, their hips a mere six or so inches apart, a slick hole perfectly lined up with... With...
Oh man. Just by thinking it, the kitten gets hit with a pang of dizziness, and at the same time his dick jumps. Even at full mast, it might not be as large as the one draped over his brother's orange tummy, but he's far too preoccupied with imagining what it could feel like if only he just leaned forward, a tiny bit, that's all he'd need to do to slide it in–
"You–" his voice cracks in desperation, and he tries again, "–You should let me do it. I mean, you should..."
"Wha- What if I get pregnant? I'm not ready to raise a family!" Darwin's hand flies to cover himself, as he momentarily snaps out of it.
"Uh, you definitely can't get pregnant, dude."
"Oh. Well I didn't know you became such an expert in... Fish biology." He narrows his eyes a bit, sounding either suspicious, or just confused. It's hard to tell.
"What?" Just like that, the two got distracted way too easily, but Gumball can't wait any longer! "N-Nevermind that. Can I? Please?"
It thankfully takes nothing more to convince Darwin, he's clearly just as eager to try it as Gumball is. Now back on track, he's repositoning himself, moving his fish tail to lay flat between his legs. A perfect seat for Gumball to straddle. The kitten's impatience is replaced with intimidation when he finally starts to put some of his weight down against the boy below him. He makes the mistake of eye contact right as he's about to proceed, and now he's all nervous.
He mutters something inaudibly, and takes a deep breath. Darwin's eyes close while he waits. A paw rests on his thigh, the other one guiding his tip inside. His movements are hardly measurable, a fraction of an inch at a time, his mouth agape as he focuses every cell in his brain on making sure he doesn't mess up here. Making sure he doesn't move too fast, when he can already feel an overpowering urge to hump like his life depends on it. The urge only grows the more he's enveloped, the indescribably hot feeling hitting him deep in his core, when he looks down and sees he's at last, undoubtedly, completely, balls deep in a goldfish.
It just... Entirely disappeared inside him. To the hilt. He wonders if it feels as intense to Darwin as it does for him. His next question comes out in a more whiny, breathless tone;
"Is that good?"
Darwin's hand rests on his pelvis, staring down in the same area. He apparently likes what he sees, judging from the drops of pre that fall from his prick.
"T-try moving a little."
Gumball's first attempt is hardly a thrust, more like an awkward rock of his hips, just to get used to the feeling. Confidence grows as he steadily starts a rhythm, and both of them can feel the resulting friction right away. He slouches, his paws curling into fists, resting on either side of Darwin’s body.
It could have been his gradually speeding pace, or the subtle change in angle as the fish lifts his lower half up into it, but the two of them hear the first squelch coming from their connecting bodies. A very normal sound in such an act, but their impulses are to laugh. Gumball's chuckle chokes out at the very end, turning into an embarrassingly heated mewl, which he couldn't have stopped if he wanted to. The weight of his arousal is making every sound, even the funny ones, unimaginably hot to him. Making it hard for him to hold himself upright. He leans down until he's almost prone, as much as he can be without losing his momentum.
He barely registers how close his face is hanging over Darwin's, panting directly onto him as he inadvertently pins him there, until he hears a squeak. He notices, through his blissful haze, Darwin chewing on his lower lip, clutching tight to fistfuls of old tarp. Every time his co*ck twitches, he can feel it poke up against his soft belly and walls throb around him at the same time.
It's so warm. He tries to push deeper than what he can give with every thrust, like he would fully merge into his body if he could. It forces Darwin's feet to lift into the air, their centers of gravity shifting the more desperate he gets. He feels the thick fish tail curl up and support him from between their legs, brushing up against his balls. He wouldn't know it, but his own tail is frantically thrashing.
"It's so, so good. It's- really good..."
The kitten's slurred words are moaned against Darwin's neck. Any reply that tries to be given can't be articulated, all he can hear is a strangled whimper. Gumball wedges his arms under the other and hugs him tight, keeping him still as he sinks further and further into his instincts.
"I don't... I don't think I can... Go much longer!"
It's a miracle he's even lasted this long from how overwhelming this is, his first time, his first taste of what he's spent so many nights dreaming about, and waking up with laundry to do. But he feels it creeping up on him, urging him to speed up, not caring about anything else. Noises freely spill from his throat, and he clamps his teeth down onto the shoulder under him. He doesn't know why, but he needs to keep his jaw locked on it, even still as he hears a sharp yelp. He responds with a muffled kitten-growl.
The rubber heels of Darwin’s shoes kick down on Gumball's lower back, making him jump. He can't see his face anymore, and his next upstroke stops short, keeping him buried inside and flush against the boy below him. It must be Darwin's legs locking him there, crossed over his back. He can't pull away, not that even the notion of such a thing crosses his mind, not when he’s so close to the edge. So close that even without a full range of motion, he could easily get off by rocking his body against him. Trying to press down more than he actually can, digging his toes down into the mattress and kicking at it, in an attempt to push more, to go harder.
Broken pieces of his name reach his ears. His body stills, and the only thing he feels is the pulsing, the tightening, and then the overflow of cum spilling out, seeping through the fur around his sheath. He can feel the legs squeeze him tighter, closer, only letting go when his jaw finally releases. He lets out one last moan, an exhausted one.
He lays limp for several, dizzy, moments. He swears his vision went white for a second back there, and can't remember if he's ever felt so fulfilled in his life before. His afterglow is interrupted by another weak little kick on his back, and squirming in his noodly arms.
"Guh... Mmwhy'd you stop?" The fish keeps rocking, trying anything he can under the dead weight to get some friction, from the softening dick that had already slipped out. When his brother rolls off, he tries to grab at him.
Luckily, Gumball gets the hint. He's not thinking straight yet, so he wordlessly returns the pressure on him, using his paw. He watches it writhe in his grasp, and Darwin melting all over again when he finally starts moving his hand. The strokes are pretty lazy, but he doesn't seem to be complaining much.
He sees how much sweat there is coating Darwin’s scales. It would be kind of gross in any other context. He can feel him twitch and tense up, and looks down to see a pool of sticky white collecting in the crease between his tail and ass, coming from under his dick, where his slit is still slightly gaped. It sends a warm shudder through the kitten, knowing it was him who made that happen.
The quiet in the basem*nt carries the subtle, breathy noises well. Gumball finds himself leaning closer to listen better, keeping his face close to his neck as he jerks him off. Something possesses him to stick his tongue out, towards a bead of sweat on his neck. He tastes salty. He laps more at him, dragging his tongue over his gills. Then over the faint bite mark he spots on his shoulder, almost like an apology.
He hears some choking whimpers that sound like they're trying to be words. He turns towards him, to catch his eyes, but at the same time Darwin lifts his head, and their faces bump together. It's not clear if either of them meant to kiss again or not, but it naturally turns to one.
The multitasking is hard enough for Gumball already, trying with his eyes closed to move his hand and tongue at the same time. And Darwin isn't even trying, just humming into his mouth and bucking upwards in an erratic way, sometimes making his slicked up dick fall from his paw and then he has to feel around for it again. He wraps his legs around one of Darwin's in an effort to keep him still.
He can tell the other is close. Soon enough his struggles to keep a steady pace on a moving, sweat-soaked target pays off, and he feels a warm fountain run over his paw. He lifts his head to allow him to breathe, and watches his contorting expression intently.
"...Was that good?" Gumball has to ask, after waiting barely ten seconds. His pride shows in his smile, as he sees the collapsed heap open an eye.
A silent nod. He's still catching his breath.
"I guess I'm really good at this, huh? You're at a loss for words from my magic touch," Gumball accents with twinkling fingers. He tries to pull a smirk, and Darwin groans and pushes his face away.
They stay cuddled up for a spell, letting reality float back over them. The stickiness coating their bodies slowly starts to get more and more uncomfortable.
"Gumball?"
"Yeah?"
"What are we gonna tell our girlfriends?"
The kitten gives a long, thoughtful sigh before he answers. He stares up at the wooden beams above him, and the dust particles floating under the old, exposed light.
"Nothing," he shrugs. "This didn't count, obviously."
"Oh, okay."
