No set narrative/POV. They're whatever age you want them to be~

also i would like to mention that gumball has indeed canonically mentioned that he shaves his ass with his mums waxing cream, obviously shaving it for darwin since he's clearly a bottom (or at least a switch). there's no point of me mentioning this but i thought it was important cause the idea of a shaven, subby gummypussy is adorable imo.

It was the middle of the summer holiday when a heatwave encompassed the town of Elmore with its blazing warmth. Two bros, Darwin and Gumball slumped into their living room couch, barely clothed with the blinds shut- being cooked alive in the scorching heat. Their parents and other sibling, Anais, had decided to go out of town for the day to witness the arrival of a brand new attraction at Daisy Land, and wouldn't be back until late during the night.

But why didn't Gumball and Darwin join in? Well, to put it light terms, they would much rather cease to exist than to hear the stupid theme song of Daisy the donkey one more time, and not to mention that they deemed themselves "too cool" to dabble in anything made for babies.

"Dude i'm so hot that my butt has melted into the couch" -Darwin groaned, wearing nothing but a pair of green shorts.

"Dude, it's more hot inside this room than the rate of the Earth rising in heat due to global warming per year. I swear dude, you could add 50 billion more coal mines on planet Earth right now and the ice caps would melt slower than if they were in this room right now. " -Gumball moaned back, sitting in his underwear that was probably soaked with sweat (ew). He was at the point of overheating where his brain function started to take a toll on him as he could no longer form coherent sentences, and was starting to get irritated by the excessive heat. It was at this moment where they truly resented their father, as he had broken the air condition by stuffing water inside of the machine- in his defence he thought it would act as a second fridge and make icicles, i guess there was a small amount of logic behind his actions.

Gumball uses the last bits of strength he had left in him to reach over for the TV remote and turns it on. The TV comes to life by blaring a random movie that was showing on the channel. It was a boring day-time movie that had the most mundane, unoriginal plot anyone could have ever thought of; the boys watched it regardless as they were desperate for any distraction to take their minds off of the dreaded heatwave.

The movie droned on with endless lines and sub plots that were completely irrelevant to the actual plot of the movie, but the only other thing on the TV was Grey's Anatomy- and the two were not up to watching a medically inaccurate, stupid, cheap, poorly scripted, cash-grabbing show.

The duo sat in silence, heedlessly watching the film. Until the movie started to get a little spicy, the main character and their love interest appeared to be making out on screen. The TV blaring noises of sloppy, wet, kissing noises into their poor innocent ears. Gumball briefly glances at Darwin to catch a glimpse of his reaction. To his amusement, Darwin was watching the screen with wide eyes with a mixture of disgust and embarrassment plastered on his face- but yet his gaze was glued to the screen out of morbid curiosity. Gumball looks back at the screen and within a split second, the characters clothes were off and they were on the bed doing the "devil's tango".

"AAAAAAAAH WHAT IS THAT?? WHAT ARE THEY DOING!! WHY ARE THEY DOING THAT WITH THEIR BODY PARTS" -Darwin screamed out in pure horror.

"Dude relax they're just making love, I'll change the channel just calm down." -Gumball snickers at Darwin's innocence being crushed in front of him. He flicks the channel to the next one, and Darwin sighs in relief.

Of course Darwin knew what sex was, he wasn't stupid. But he has a tendency to act dumb and oblivious most of the times.

Gumball being the evil man he is, picked up the remote once again and flicked the channel back to the previous one, where the couple were still rawdogging each other on screen. Darwin resumed back to screaming, flailing his arms in the air, and sighing in relief when Gumball switched it to the other channel. But then Gumball switched it back, and then off, and then on, and then off repetitively in a teasing manner.

Gumball laughed in amusement at the sight of his lil bro switching his emotions from one extremity to the other in rapid succession, seeing how long he could push Darwin's buttons before he snapped. Until the heat started to affect his body more, and he eventually lost grip of the TV remote to his sweaty, slippery fingers. The remote fell to the ground in slow motion, clashing against the carpet and spilling out its batteries and contents across the surface of it. That was it, they had broken the remote again and to their horror, the TV was now stuck on the sex scene of the couple. There was no other option but to cover their eyes and wait until the scene ended, as manually changing the channel on the actual TV itself was too much of a hassle.

"DUDE I CANT TAKE A MINUTE LONGER OF THIS AGONY" -Darwin screamed out.

"DUDE CHILL OUT! We'll just cover our eyes and wait it out!" -Gumball reassured him, clasping his hands over his eyes. He decides to take a peek to make sure Darwin was alright, but notices that he was staring directly down towards his legs. He removed his hands away from his vision to see what Darwin was looking at.

"Hey dude, you alright?" -he asked, only to realise seconds later that Darwin wasn't actually looking at his legs- he was looking at what was growing in between them.

Darwin looks back up at Gumball with his cheeks slightly tinted red.

"Uhhhh dude I think it's broken or something" -Darwin mutters shyly, slightly embarrassed but still trying to maintain his oblivious act.

Gumball looks back at him, trying to stifle a laugh, "Dude, you have a boner"

"Well what am I meant to do?"

"I think you need to 'jackhoff' or something"

"Well how do I do that?"

"Dude, I love you but there's no way i'm gonna tell you"

Darwin looked back down at his groin, it was starting to feel uncomfortable as the tent in his boxers grew. He looked back up at Gumball with desperate puppy eyes, trying to subconsciously guilt trip him into telling him.

"Finee… I'll help you but it would be too awkward to tell you instructions directly so i'll just show you a video" -Gumball groaned, unable to resist Darwin's pleading face.

The duo climbed up the stairs, Darwin holding onto his crotch area to try and not expose himself to his big brother. Meanwhile Gumball was trying to hide his face as he started to feel flustered, but he was still determined to help out his best friend. He logged onto the family computer in his room and went onto the internet. It wasn't Gumball's first time ever watching porn, he often snuck his phone into the bathroom at night to satisfy his needs. But he'd never known if Darwin had ever witnessed pornographic content, but judging from his innocence -he doubts that he has.

He types in "Pornhub" into the search bar and clicks on a random video. The video starts and it's one of those cliche step-bro and step-sis videos where the chick is stuck in a microwave or something dumb.

Gumball seats Darwin in front of the screen, "Okay buddy, all you do is just take off your pants and just play around and tug on it. I'll give you some privacy and watch some more TV downstairs". He turns around and takes a step, before being tugged back by Darwin clinging onto his arm.

"Please don't leave me alone" -Darwin pleaded with him, his eyebrows furrowed into the saddest expression ever.

Gumball stared at him in confusion and awe that his brother was really asking him to stay as he jerked off to porn in front of him.

"Dude I dont think it would be very appropriate for me to sit here and watch you" -He explained to Darwin, who had begun to manage to well up petty tears in his eyes to further guilt trip his big bro into staying.

"B-but I need some emotional support, what if I do something wrong and wind up into a terrible situation. And besides, the video has two people in it." -Darwin. Gumball lets out a long sigh, pulling up a spare chair to sit on and placed it next to Darwin's chair.

Darwin secretly lets out a smirk of triumph, he loves it when he gets his way. He begins to undress the very few items of clothings he had on him, and got to work- or at least attempted to.

His lack of fingers made things harder than it should be, and Darwin gave out small grunts as he struggled to get a proper grip onto his rock hard cock. At this point, he wasn't even paying attention to the video at hand, solely putting all his focus on himself.

As much as Gumball tried to not peek at him, it was quite hard to ignore the younger's struggled attempts at pleasuring himself. And as much as Gumball didn't want to admit it, 'cause he knew it was weird to have these sorta thoughts about your own brother, but it was quite adorable watching him.

Gumball thought to himself, 'He sorta looks quite cute, being all innocent and unable to help himself. Oh shoot, i'm starting to get hard myself, maybe I should leave and go to the bathroom cause it would be too weird jacking it in front of your brother'.

He didn't even realise that he was staring so hardly at Darwin's stiff cock to realise that Darwin took notice.

"Something wrong Gumball?" -Darwin smiled at his older brother, with a somewhat devilish smirk on his face. Darwin looks up and down at Gumball, who was now blushing in embarrassment after being caught. Darwin notices the big bulge that has formed in Gumball's underwear.

"Oh! It seems like you've got the same problem as me now! Maybe you should take off your pants and 'jackhoff' with me!" -He smiled and stared at Gumball, slightly pressuring him with his gaze to take them off. Gumball thought about it for a second and complied, 'I guess there's nothing wrong with pleasuring yourself with another dude in the room, friends do it all the time! I think..'

He threw his undies away somewhere on the floor, leaving the two boys naked. Darwin seemed pleased with this, and started to rub himself off without much hesitation. He used his index finger to swirl the pre-cum that has gathered around his hole and smeared it all over his tip. His eyes fixated on the video as he paid no attention to his surroundings and mindlessly played around with his cock. He decided that he'd had enough of the foreplay and finally gripped a hand around his shaft, using the pre-cum as lube. He groaned a little, biting his lip to stop himself from being too loud as the window was wide open to help cool the room down.

However, he hadn't noticed Gumball, who was very much the opposite of Darwin right now. He felt slightly self conscious about himself, more so about his dick size. He had seen Darwin's cock a handful of times as they both shared a bedroom together, and were comfy enough around each other to the point where they weren't phased by it. But never had he been in a sexual situation like this, and seeing Darwin's cock hard like this made him horny for some reason. He knew it was bad but, he couldn't help the way he felt. Not especially when Darwin's dick size was leaning into the 'bigger than average' end of the scale; caused him to feel more embarrassed about his size despite him having an averagely sized cock himself. He tried to stop peeking at Darwin, but his eyes naturally kept on wanting to gawk at him, it was much more entertaining and hotter than whatever video was playing right now.

Gumball tried to inconspicuously jerk off to Darwin, as he brought a hand to his ever growing shaft that only got harder the longer he stared at his brother. Nervous beads of sweat rolled down his forehead, as he tried to not get caught.

"Hnngh~" -Gumball groaned under his breath. As much as he tried to please himself, his subconscious grew on him as the guilt of 'wanking over your brother' was starting to get to him. It was getting harder to maintain his erection, but yet he was determined to last just as long as his brother did.

"You look like you're struggling Gumball, are you starting to not enjoy the show im giving you anymore?" -Darwin playfully questioned whilst lightly jiggling his cock around and bouncing it in the air; his voice catching Gumball completely off guard.

Gumball jumped up in his seat, "Oh, I- uhh,"

Darwin swiftly stood up and bent over, placing a finger on Gumball's lips to shush him.

"Shhhh, just relax and let me help you bro, I got you."

Darwin's finger trailed from his lips down across the middle of his torso and ran it along his happy trail. He spreads out Gumball's legs to make some room for him and got onto his knees, looking up to see Gumball's expression.

"A-AH! D-D-Darwin!! What are you?" -Gumball screamed out, squirming in his seat and gripping the desk beside him tightly. Despite him seeming to be dreading every second of this, his area down below was telling us otherwise. In fact, he had never been more harder in his life than in this moment.

"Just chill out dude, I won't hurt you! I promise~ " -Darwin winks at him, loving every second and every reaction he was getting out of Gumball.

"D-Darwin this isn't r-right- hnngh~"

Gumball couldn't help but moan as the sensation of Darwin's hot tongue swirling the pre-cum around his tip overwhelmed him. Darwin slid a hand underneath Gumball's balls, lightly gripping them and using his thumb to ever so gently stroke the sacks. This caused Gumball to yelp out in immense pleasure, as he tilted his head back into the top of his chair.

"G-Gosh darn it, ahh~" -Gumball moaned out in staggered breaths, he felt so defeated under the control of Darwin's fins. Darwin continued to play with the tip, fiddling around with it in his mouth like a lollipop. He mentally prepped himself before slowly inching his lips around Gumball's shaft and towards his base. Thankfully Gumball had shaved recently, so no bits of hair irritated him or got in the way. Gumball moaned at how good it felt for his cock to be hugged and embraced by the warmth of Darwin's mouth.

Darwin made sure to relax his throat as much as he could to minimise his gag reflexes from kicking in, and placed a hand on Gumball's thigh- rubbing and gently squeezing the inner parts to add an extra sensation. The other hand was placed against his balls, occasionally rolling the tips of his fingers against the sacks. He slowly bobbed his head up and down, running his tongue along the vein that bulged out of Gumball's shaft with each head motion. He only began to pick up the pace as soon as he felt a little more comfortable with the brand new sensation of having a large object in his mouth. He made sure that Gumball was enjoying himself as he adjusted to his size, occasionally sucking in on him as if he were sucking out of a straw; his hollow cheeks caving in around Gumball's length tightly like a warm hug.

The two boys were starting to sweat a lot more the longer Darwin was sucking him off. Gumball felt his knees buckling into Darwins torso from pleasure, as the heat made him feel more limp, as well as moaning a lot more louder. He couldn't even hold onto the desk anymore from how sweaty his hands were, so he instinctively placed a hand on Darwin's head, gently stroking it in a loving manner. His cock throbbed with pleasure and the emotion only grew as Darwin sped up. Wet sloppy sounds started to fill the room as a mixture of spit and Gumball's juices dribbled down his chin. Darwin himself felt a throbbing sensation from his own cock, so he removed his hand from his brother's thigh and started to passively tend to himself and multitask.

Gumball's groans got louder, "Hnnngh~ Darwin I think i'm gonna-"

Darwin immediately halted his actions and forfeited from touching him any further. He looks up at his brother in a playful, yet seductive manner, "Do you trust me gummypuss?"

Gumball was taken aback by the question, though he was still dazed from the feeling of wanting to release his load, as well as the intense pleasure he was receiving beforehand. He nodded, hoping it would make Darwin continue finishing him off as he slowly started to feel himself going limp with each second of no-contact.

Darwin stood up and straddled over his best friends legs with an arm wrapped around Gumball's neck and the other on his dick, carefully aligning it up with his right hole- maintaining eye contact with the elder. He watched as Gumball's eyes widened in shock, but was far too deep into their motion to do anything. Darwin had already sucked him off, there was no point in getting heated over doing the next step, right?

Once Darwin had the tip of Gumball's cock perfectly in line with his hole, he asked in a gentle voice, "You ready?"

Gumball gave a shaky nod, his hands trembling slightly as his brother was about to take his virginity. Darwin slowly lowered himself, thankfully it was a whole lot less painful due to the excessive foreplay they had partaken in, but still he winced at the mildly sharp needle pain- for of course it was his first time having sex as well. He continued to lower himself whilst giving himself time to adjust to the feeling of his hole being stretched out. Darwin moaned as he felt his insides start to fill up with Gumball's shaft. He bit his lip and leaned a little forward into Gumball to make it easier on himself, until he felt his ass reach the base of Gumball's cock. He sat there for a while, just until the pain eased. He could feel Gumball's hot breath against his collarbone, the sweat dripping off both of them as if they were in a sauna, he didn't know how he's gonna muster the energy to make them both finish in the dreaded heat.

That's when he was taken by surprise, as he felt a pair of hands holding him down by the waist, and a pair of soft lips pressed against the dark skin of his torso. He felt as Gumball started to suck down on the spot, gently biting it until it bruised into a dark purple shade, marking Darwin as his. Darwin ran his hand into Gumball's blue hair, gripping it as he squeezed his eyes shut and made little whimpers.

It was that moment when Darwin realised the shift in power laid more towards Gumball, as the elder started to gain confidence.

Gumball slowly assisted Darwin by slowly lifting his body up by the waist, and then back down again- slowly thrusting into him as he does. He felt he was going light headed again as the pink walls of Darwin's insides clamped and squeezed down onto his shaft; causing immense pleasure. Darwin started to glide himself up and down Gumball with more control as he felt his muscles relax and his hole loosened, and he started to bounce up and down on him, his bare cheeks slapping against the skin of gumball's thighs. Gumball rolled his hips into Darwin, moving his hands to Darwin's cheeks to spread them open and cushion it whilst working him open.

Gumball felt himself slowly getting closer to his climax within a matter of seconds of just listening to the wet, sloppy lewd noises that filled the room. Darwin seemed to also be reaching his limits too, as he clasped a hand over his mouth and squinted his eyes, choking back moans that were borderline turning into sobs. He felt his warm tunnel send waves of pleasure that were released from the bottom of his body to the top. With each loving thrust, they both could feel themselves wearing themselves out, both slouching into each others bodies whilst breathless.

With one last final thrust, Gumball felt his legs give out as he couldn't hold back his essence any longer, letting himself let go inside of Darwin. Darwin tenses his muscles as the feeling of his insides being flooded with Gumball, triggering a domino effect of orgasms. He felt Gumball's cock twitch inside of him, and his hips buckling underneath his legs as every single last drop inside of him was benign emptied out. Darwin smiled, pleased at his work as he looked down at Gumball, who was gushing in shades of red with his head leant back into the chair, mostly from the gruelling exercise the two had indulged in. The sight was almost worthy enough of Darwin feeling up to round 2, but decided to leave his brother alone for now- mainly because he felt Gumball now going limp inside of him. Darwin leans into Gumball's torso, wrapping his arms around his neck and hugging him in a tight embrace, still attached to him below and cockwarming him. Gumball returned the hug and wrapped his lanky arms around Darwin's waist.

"Darwin, you definitely made me stay here on purpose didnt you?" -Gumball asked in between breaths, still exhausted. None of his previous adventures have ever physically worn him out this much.

"Maybe~" -Darwin teased, giggling to himself as he buried himself into his elder's neck.

"You really aren't as innocent as i thought you were y'know. But you absolutely cannot make me do anything like this in the future, i only did this because i love you. A-and nobody can know about this.."

"Yeah yeah I get it gummypuss, this stays between us and i _wont_ ask you to do anything like this in the future."

The two kept their silence and basked in the peace, almost nodding off asleep in each others arms, their presence almost intertwining into one with each other.

Until Gumball's phone started to buzz on the desk, it rang for a while as the two didn't want to depart from each others embrace, despite the humidity. Gumball peeked an eye open to check who was calling him.

He shot up with wide eyes, -"Shoot, Penny's calling"

BONUS:

The clock buzzed 11:39PM and the rest of the Watterson family had arrived back at the residence from their trip from Daisy Land. Feeling tired from all the adventures, they had all decided to go to bed and rest.

Anais entered her room that she shared with her brothers, only to notice the computer was on, but the screen was black as it was on the screensaver setting.

"Oh, they must've left the computer on again."

She looks over to Gumball's bed, to notice that both he and his brother were fast asleep, cuddling each other only wearing their underwear. She shrugged it off as typical boy behaviour as it was pretty hot today. She did however find it mildly strange that Darwin was sleeping in Gumball's bed other than his fishbowl, but assumed he had a nightmare or something.

She walked over to the computer and questioned herself, _'I wonder what they've been up to all day'_.

She wiggled the mouse, and the screen sprung to life before her vision.

But oh how she wish she didn't have her eyes, for a pornhub video popped up on the screen with a petite, blonde white woman being dicked down by 5 big black guys.
