A Tale of Two Brothers: Donnie & Marco

 

There was nothing particularly remarkable about brothers Marco and Donnie Diaz. Born to a mixed white and Latinx family they were raised predominantly by their father, Mr Diaz, after their mother walked out when Marco was just 6 and Donnie was 2. Mr Diaz worked for a local private science group and their lives were perfectly normal and respectable – they went to church every Sunday, Donnie studied hard and Marco hardly studied now he’d graduated high school and dropped out of community college after a couple of years.

 

Out of the two brothers Marco, the older, was definitely the less inclined to hard work and study. He enjoyed gaming, drinking and sleeping in until well past midday – oh and masturbating of course. He was handsome, and had broken more than a few girls hearts with his tanned skin and thick dark chestnut-brown hair. He favoured sportswear and silver jewellery such as his fine silver chain necklace. If there was one thing he hated though it was his glasses and he swore to get laser eye surgery when older. The one thing Marco did put effort into was sports and he particularly enjoyed basketball, despite being only 5’9’’.

 

Younger brother Donnie on the other hand was adorable, but more in the way that you just wanted to take care of him. His skin tone was paler but his thick tousled hair darker and he was even shorter than his brother at just 5’6’’. Like Marco, he too wore glasses, though they complimented his bookish personality. Whereas Marco liked dark clothes, Donnie favoured bright, peppy colours and a silver crucifix hung around his neck. Donnie studied hard and clearly had a similar mind to his father, fascinated by science. He was shy though and kept his head down, he did not have his brother’s confidence.

Donnie and Marco didn’t exactly along and were prone to arguing or fighting, usually provoked by Marco when he was bored or restless. This was worse during the week when their father would leave them to look after themselves now they were both of age. Recently his work had meant he was frequently away until late at night leaving the boys to look after themselves. Though Marco was in technically in charge, it was unsurprisingly Donnie who took up most of the cooking and cleaning.

 

“What are you working on, dad? What’s the top secret project?” Donnie would ask excitedly, his scientific brain whirring with possibility. But Mr Diaz would only chuckle and say it was more than his pay grade to tell Donnie that. After Mr Diaz left the room, Marco would snigger and flick balls of paper at Donnie calling him a “nerd”, though he too was privately curious. Over weeks the brother’s curiosity would lead to them trying new methods to getting their dad to share what his work was – Marco believed it must be some sort of secret FBI technology, whereas Donnie felt it must be a project for sustainable energy. Mr Diaz however never gave anything away. The brothers didn’t even know the name of the company their dad worked for!

 

Their routine continued unremarkably until one week where Mr Diaz abruptly announced he would be away the full week for work – it was a crucial time for the project and he needed his sons to look after themselves. That same Monday morning he loaded up his car with his briefcases, laptop, loading cases and other paraphernalia and gave his sons a big hug goodbye.

 

“You look after your little brother, now – you’re the man of the house after all” he joked, tousling up Marco’s hair to Marco’s annoyance. Donnie smiled resignedly, knowing it would be a week fo Marco doing sweet fuck all, whilst Donnie tried to keep on top of things, all the while that Marco would either be in his room jerking off, off out drinking with mates, or existing purely to wind him up.

 

They watched their father drive away before Donnie headed back up to his room and study. Marco however wasn’t going to waste a minute. Although Donnie was the one always asking about his father’s work, Marco was dying to find out. He might be lazy, but he wasn’t stupid and his father’s secrecy was more than enough to raise his suspicions. Hell, if it was some Musk level science shit their might be some serious money! So as soon as his dad was out of sight and Donnie was in his room, he snuck into his dad’s study.

 

The room was called a study but was more like a home laboratory with multiple screens, fridges, freezers, centrifuges and test tubes. And it was a bombsite. Marco stared in shock – it looked like it had been raided, or that Mr Diaz had left in a hurry. Cupboards were open, scraps of paper everywhere, lights flashing. Marco held his breath as he looked across the notes and logs and calculations – only nothing made sense to him (he was not a natural scientist after all).

 

For a full half hour he carefully searched for some hint of what the project was when he discovered two vials in the smallest fridge, filled with bright green liquid. They were labelled differently:

 

“H1-M80 formula: premium. Masculinity and Virility certain.”

“H1-M80 formula: unbalanced, Effects uncertain.”

 

Now, he may not be bright but he knew what masculinity and virility meant. He looked again at the notes strewn around him – phrases jumped out at him, now making more sense: “increased libido”, “significant mesomorphic growth”, “testosterone output exponential”. He also knew that his future didn’t lie in hard work and study. He grinned as he pocketed the two left over vials – he knew what he planned to do with one but it would be a shame to waste the other. He chuckled softly to himself as he looked up to a framed photo of him and his stupid, dorky brother Donnie…

“But you never make dinner?” Donnie said suspiciously as they sat down for Marco’s home made curry that evening.

 

“Well bro, I realise I’ve kinda been a dick to you and… well I just wanted to make it up to you this week. Now – eat up!” said Marco, uncharacteristically sweetly.

 

The curry in fact didn’t taste half bad! Though there was something about it which tasted… different to any other curry Donnie had tasted before. “Marco, what exactly did you put in this curry?”

 

“oh just some… buffalo sauce… secret recipe tip” Marco lied, quickly and efficiently.

 

“Well, I guess it did the job!”, Donnie hesitated a wary smile at his brother before tucking into the rest of his meal…

 

***

 

The next morning Donnie woke up feeling like his head was full of fog. As he stretched he didn’t notice that his bones seem to click and pop a little more than usual. He winced as his watch felt like it was digging in, so he loosened the strap. Wearing just his pyjama pants he frowned at his more-persistent-than-usual boner. He chanced it and hesitated before heading into the corridor to head to the family bathroom. He let himself in and gasped suddenly as he saw himself in the mirror, pyjama bottoms tented. Firstly – his previously slightly doughy body was toned now – he had a flat stomach and even a slightly proud pair of pecs. A dusting of dark hair worked up his abs and he gingerly touched the growth of small dark hairs on his top lip.

 

“Looking butch, bro” chuckled Marco’s voice and Donnie span round to see his brother – once taller, now a similar height, stood in nothing but bulging boxer shorts. He too looked buffer – he had always been lean but now he looked like an actual gym-jock. Donnie’s eyes couldn’t help but rake over the broad tanned chest and impressive bulge before he yelled and shoved his brother out the room before he washed and hurriedly shaved his face smooth again.

 

Later, as he was forcing his way into a now too-tight t-shirt which now revealed an inch of belly and those pesky trail hairs and showed off his new lean body shape, he noticed with horror that the upper lip hairs had grown back, thicker and darker than before.

 

He tried to spend the rest of the day as normal, but he couldn’t help the looks he got in the coffee shop (was the nerdy, twinky barista actually checking him out?) or the librarian asking if he was feeling okay, as he could feel his clothes getting tighter. Donnie just nodded his head, stifling a groan at the pain in his stomach.

 

As soon as he got home to his room he tore off his clothing and, shocked at his own pent up horn, jerked off over his bed before passing out to sleep as, unbeknownst to him, Marco grinned and watched through the door crack, gently rubbing his own package…

 

***

 

The next afternoon Marco grinned himself in the mirror as he hauled his naked ass out of bed. His small pecs have increased in size and his arms ache as his forearms look thicker and meatier. His biceps swelling a little as his hands too look broader. Marco can feel every bit of pain in his transformation as his spine lengthens his back making him just a little taller. His feet have grown outward, by a couple inches, as his butt stands pert, round and proud. His cock and balls begin to swell and grow more as his balls fill with new fluids of a man growing. His legs feeling heavy as his calves bulge out. Marco doesn’t even feel the changes, only the fresh breeze on his exposed now cock and balls which he fondles. Sexy stubble peppers his chin but unlike Donnie he doesn’t seem to have grown any body hair – if anything it’s starting to retreat. What was once a thick bush is now stubble around his thick cock. He fingers a drop of pre as he hears his bro yell in shock as he too wakes up late and stumbles to the mirror.

 

Donnie stands before his mirror, hands clutching his body as his pecs bounce as they slowly swell. His arms even larger than the day before. His legs getting more muscular, years of intense workouts can’t even compare to what his legs seem now. His abs have pushed out of his flat stomach forming a nice 6-pack. His Adam’s apple too has grown and is now quire prominent as his groans get deeper. His facial hair growing at a faster rate then before giving him a clear developing moustache as well as stubble across his jaw. His skin tight as his acne starts to fade away. “What the actual fuck” he whispers, before gasping at his new, lower voice.

 

He runs to his brothers bedroom and stops in the door as he sees Marco reclined on the bed stroking his thick, uncut cock. “Sup bro”, Marco winks.

 

Donnie runs out the room, scrambling to pull on some red joggers. He stocks up on food from the kitchen and returns to his room, locking the door, only he can’t get the image of his muscled up bro stroking his cock out of his head, he curled up in bed and slipped into an anxious sleep.

 

Meanwhile Marco spent the afternoon switching between jerking and sending pics of his new body and cock to all his snapchat contacts – male, female, he just didn’t care – he wanted to show off! Many didn’t believe him, but it didn’t matter. He just liked the attention of it all.

 

Donnie woke up that evening to his head having this painful throbbing sensation. He ran into the bathroom to see if there was anything to treat the headache, but there wasn’t. The pain got worse gradually. He clutched his head as his deep groans filled the room. The ache was too much. His tears ran down his face, he wanted it to stop, but it didn’t. In fact, the headache start to feeling it was changing him. He tried to think, but found it difficult to even think of a solution. Usually, whenever he had a problem, he could figure it out in the matter of seconds, but now this was a problem he couldn’t solve. Tears stung his eyes as the pain of his head felt worse, his thoughts all foggy and uncertain, unable to think much.

 

The one thing he could think of was that image of his brother on the bed. Slowly, almost unwillingly, he released his thick cock from his red sweatpants and grabbed one hand around his dick and started stroking. He had never been like this. Each stroke was making him feel better in many ways. Donnie jaw dropped allowing saliva to fall on his dick. Thoughts of his bros body and cock filled his head and he liked it – he imagined his brothers butt jiggling and cock swinging as he felt pressure build up in his dick. He was going to release. Donnie was ready and didn’t care where it would land as long as the dumb headache would go. And it did. Donnie let out a white stream of cum as he laughed dumbly as the stream splattered up his abs and his pecs… wait his pecs!? He scrambled to his feet and the panic returned as he noticed those tight pecs had grown… only now they were round and bounced as he panted… hell they were almost like breasts.

 

A cold sweat broke over him as he muttered to himself, “What in the name of God is happening to us…”.

 

“We’re becoming Gods bro” came a voice from the door, and Donnie looked over to see Marco flexing as he winked once more – “oh, and thanks for the show.”

***

The next afternoon Donnie woke up in a big sweaty mess as he grunted and grown – a mix of plain and erotic pleasure. He starts grinding on the bed not being able to control himself at all. He tries to stop but it feels so good. His body producing an odor of a heavy sweat. He can feel his body swelling again. His pecs bulging and becoming rounder. His arms becoming bigger as more dark hair sprouts over his body. His genes are rearranging. He doesn’t even realize how big he is getting, since he is too busy fucking his bed. His balls growing larger as Donnie moans, nipples growing wider. He uses one hand to rub them as he moans louder with each thrust put into the bed. He can feel his head aching again as he needs to release his cum. He needs to breed. He needs to fuck something. Donnie is terrified but at the same time he secretly loves it. His feet grow larger as they hang off the bed, also sprouting dark hair. He is so big now. Donnie’s face changes as his face matures, looking older – more like a man in his 30s now. . The pressure is building up and too much to hold and the bed sheet are filled with sweat and pre cum. He moans loudly one last time as thick cum spurts over his round chest, face and headboard. Donnie rolls into the big mess he has made with his mouth open and tongue out, trying to lick up anything he can. Donnie can’t control himself anymore. He just needs cum now. He doesn’t want anything else. All the times studying wasted when he could have been jerking his cock.

 

Donnie walks up to his mirror, noticing how big he is and how much different he looks. He fucking loves it as he flexes his huge hairy arms. He loves how big and bouncy his balls are. Even if he shaved the monster of hair on his balls would grow back in the matter of hours. The drool on his face is wiped as he rubs his large nipples. He loves the feeling and so he rubs more vigorously, vaguely wondering where his hot brother is.

 

***

Meanwhile Marco is already out – he got up early and hard as a rock, his height has shot up overnight as had his muscle mass and cock size. Pulling on some tightly stretched active wear he ventured out into the world in search of some release.

 

He found it when he swaggered into the coffee shop his bro would always go to – and there he is, that nerdy, kinda cute barista that is clearly gay – nametag reading ‘Joel’. As he ordered a latte he leaned forward and whispered into the nerdy twink’s ear to meet him round the back in 10 minutes.

 

10 minutes later Marco’s moans echoed round the back of the building as gagged and tried to take in his huge cock in his mouth. Between slobbering and sucking the twink would marvel at Marco’s tanned huge muscles and Marco would just laugh and cock slap the barista. Joel used both his hands to rub the huge dick and inhaled the sweat from Marco’s hot hairless body. He bathed the huge balls with his tongue as pre spurted and stained his apron.

 

He was so taken up with his task that he barely noticed Marco’s dick getting larger and fatter, or even that the foreskin seemed to fade into his fat, long, dick. Marco’s head hair remained full though it receded slightly up his forehead as his face matured more – jawline pushing out and lips plumping up. His swollen pecs and abs become more noticeable as they bulge yet bigger.

 

It wasn’t long before Marco roared and shot thick, gloopy cum over Joel’s face. Joel collapsed spent and stared up at the God.

 

“Are you free this evening?” he panted? Marco just laughed cruelly and took a long piss just feet away from where Joel lay. “Not for you, nerd” he scorned before tucking his bulge back in his sweatpants and walking away.

 

Joel just lay their in the cum in a daze – why did he always fall for the big douche men, why couldn’t he find a nice guy – like that Donnie guy who always comes in. Thinking of which, he hadn’t seen Donnie in a few days now…

 

***

 

The two brothers stare at each other in the kitchen. Both have changed so much they start to look unrecognisable. Marco’s stubble has pushed out into a goatee as his bodybuilder sized bronzed mahogany body ripples. He once again stands over Donnie, who looks significantly older than his bro now – lines across his face as a moustache bristles over a heavily stubbled chin. They are both stark naked – both cocks well over a foot long.

 

In a brief moment when the fog has lifted Donnie stares at Marco with sadness and fear as he whispers “what did you do to us?”. He then gasps and clutches his round pecs as they inflate and grow bigger than his head, his bubble butt swelling out real thick as specks of grey appear in his dark hair. Thick dark hair not only covers his pecs, surrounding wide saucer sized nipples, but also his ass, shoulders and lower back. Abs push out, softened by the layer of paunch in top.

 

Marco too feels his mind fading as his massive square pecs push out, obscuring his view of his feet. His lips swell as his eyebrows get thicker and untrimmed as his face aged up too – grey streaks through his thick dark chestnut hair. His brown nipples swell wide too, though nothing compared to Donnie’s tits. He plays with his smooth pecs and huge nipples as he feels his once younger little bro, step closer, breathing heavily.

 

Marco moans as he feels Donnie’s hand encircle his heavy cock. Marco moans and nods in encouragement, maintaining intense eye contact with Donnie. Donnie lowers his eyes and starts to suck on Marco’s big brown dark nipples. His veins swell and flex as the taller man’s muscles expand even more, his height creeping up. His feet swell disproportionately large for his body, as do his hands, giving him an almost primal look. His cock spurts pre violently as it swells like a balloon, balls hanging lower.

 

Donnie bites his lip and seductively turns round and bends over revealing what was once a tight pucker is now a throbbing, swollen donut ring of a hole between two hairy globes.

 

Marco licks his lips…

SOME WEEKS LATER

 

‘NastyPig’ was one of the most famous leather and kink clubs in the USA. Men of all sizes and tastes gathered from across the states to descend into debauchery, and tonight was a special night.

 

On the raised stage was a banner with bright red letters encircled on a black background: “D&M”. Onto the wipe-clean stage strode two Gods of men. One, aged maybe mid 40s, was a 7 foot, ultra tanned, goateed muscle god. His shoulders so wide revealing a barrel chest with two brown nipples the size of dinner plates. A thick cock, at least two feet long, swung below his meaty thighs.

 

The other man was mid-late 50s and was shorted but wider. He had a kind friendly face with a salt and pepper moustache. But the most remarkable thing about him were his colossal bouncing tits, with enormous nipples the size of dinner trays. A silver crucifix on him looked absurd on clearly such a pig of a man. Both men wore leather harnesses, and also glasses. It was an unorthodox choice for two such virile, masculine men, but their fans felt it gave them a unique look – like nerds gone butch.

 

The two men on stage faced each other and started sensually making out, the taller one reaching round and unmistakably slipping a thick finger inside the other’s puffy hole.

One musclebear leaned to the man next to him and whispered: “Y’know, I heard they’re secretly brothers?”

Mr Diaz smirked and nodded as he watched the show escalate until the shorter man with the breast like pecs was on all fours, panting and moaning like a slut as the taller muscle man pushed his whole hand in his ass, right up to his elbow.

“I know.”

Please do! As for ideas; what about a Variation on the theme: A generation of first cousins, three sets of them, similar in age, all sons of otherwise unremarkable brothers. None of them knew their paternal grandfather having passed when they were just infants, nor did they know of his special physical attribute but slowly they learn about the genetic trait they all inherited. Prior to their remarkable physical changes the cousins hadn’t been particularly close but with each unprecedented growth spurt they quickly bond over the unique feature they all share.

I leave the rest of the story for you to run with should it inspire you- or not.
as for some visual inspiration I include a photo from the archives of gay porn, a trio of brothers that capitalized on their shared genetics and turned it into careers in adult film. Hopefully the image of the Rockwell Bros will spark the illustrator in you to create your own images and a new story. Regardless, 8FC63848-719E-4EA1-9DEC-FBF53FE4C717.jpeg.fd075a5d20365be5dbdc3d5402f97dfd.jpegI anxiously look forward to enjoying what your “naughty” mind comes up with.
