Jack walked out into the kitchen and grabbed a carton of orange juice from the fridge. He lived alone with his brother, Tyler. The lucario didn't bother getting dressed in the morning, often walking around the house in the nude. Tyler walked into the kitchen, he was far shorter than his older brother, a bit more of a gut on him to walking around in an oversized sweater that hung low enough to cover his bits. His older brother on the other hand would struggle to hide his away his balls the size of softballs and that cock must have been well over ten inches… Not that he ever stared or anything, just hard not to notice when he's waving it around all the time.

Jack was only a year older than Tyler at 23, yet he looked so much more mature. They were living together because Jack managed to get a place on his own near the collage Tyler ended up going to, and it was fair cheaper just to live with him rather than those cramped, expensive dorms. Tyler grabbed a leftover slice of pizza from a container in the fridge and put it in the microwave. Tyler looked up at his older brother naked as the day he was born, built like a tank. Tyler tried to focus in on his brother's face. “C-can I ask you something, Jack” His brother looked over leaning back against the stove still sipping on OJ. “Sure”

Tyler had been tempted to ask for a while now since moving in with him and being reminded by his ripped body every single day. “W-well I know you've been working as a personal trainer a lot, so I understand if you'd rather not in your free time, but maybe y-you could help me get in shape?” To be honest he wasn't worried if he'd help him, his brother had always been helpful, he helped him evolve to a lucario when they were teens. It was more a worry about what kind of suggestions he'd make, he still remembers all the times his brother made him work out naked in the rain. Because freshwater was good for the body, or when he'd insist on joining him in the shower after to guide him on post cleaning stretches.

The no pants in the house rule also sent up some red flags. Tyler was not into it at all, yup totally not into seeing his muscular brother naked all day, nor did he care for all the times he'd give him messages after a stressful day at school. His heavy muscular body and that thick throbbing cock out in about all day every day. He totally just lived here because they were brothers, and it was convenient. Jack smiled at his younger brother and stopped the microwave before tossing the semi cooked pizza in the trash. “Yeah, I can help you out, but we'll need a few new rules. First no pizza, second clothing just gets in the way of exercise, so the no pants rule will be extended to a no clothes rule I'm always naked and look how fit I am.” Tyler sighed, he expected as much. “But coronation does not mean causation.”

Jack pulled his brother in close with one muscular arm before pulling up his hoodie and tossing it aside. Exposing his chubby gut and soft moobs to the open air. His seven in cock and golf ball sized orbs dangling down, the boy blushed brightly. “Nonsense, it's not like it'd hurt even if it doesn't help we're brothers!” His boldness was unrivaled when he wanted something, Tyler was just waiting for him to declare nighttime group bed exercises a thing before dragging him in. An awful thought and not something he fantasied about slightly before asking his brother for help.

“Last thing, a little one off thing to get us started, we need to get you some testosterone.” He was really in his younger brother's face at this point, grinning like a lewd demon. Tyler blushed brightly, wait was he really about to make a move like that on him was he really going to breed him no no no he just means tablets or something. He wouldn't really just start fucking him, would he, in the middle of the kitchen. Maybe press him up against the window and rail on him all morning till he could hardly walk. Tyler closed his eyes and his cock flared to live, standing up and twitching from that decree from his brother.

The older lucario smiled wide before pulling away slightly. “I know a technique that works wonders, I even did it myself with a friend about a year back when I was trying to really bulk up for interviews at gyms. You let a much stronger guy turn you into their balls for a few days. Then, when you reform, you'll be full to the brim with testosterone, and it'll make bulking up super easy.” Tyler's blush filled expression turned flat, looking over at his older brother. His twitching cock didn't go down per se, but he did hold a very what the fuck look on his face. “Like vore?”

Thoughts run wild in Tyler's mind, was he admiring his body all those times, or was he just treating him as a chicken wing. Were all those lewd looks about how tasty he looked, instead of fuckable. Was he just trying to make sure all the right bits of him were tender when he'd help him in the shower, all those times? Jack shook his head and chuckled. “No no no… well sort of but not like I'm eating you for sustenance, if anything you'd be draining my balls a bit when you come back. It's more like merging or transformation, but it's totally safe, I did it with a friend I trusted a little over a year back now. You already have the bulk, no offense, you just need a little hormonal and physical help getting it into muscle. Once you're back, we'll do a few months of training and maybe get you even bulkier than me!”

The idea was nice being strong like his brother, but that still sounds super risky. “W-what if I get stuck also wouldn't it be super weird since we're brothers?” Jack pulls his brother in close again and starts walking him out of the kitchen over to the couch to sit down with him. “Look, you won't get stuck as long as you're with someone you trust not to keep you, and you know me, little bro. And I get it might be a little weird since we're related, but this practice actually comes from a place of tradition. My friend who did it to me told me it was an event fathers would do with their sons after their 20th birthday if they felt they weren't developed enough to live on their own. So it's like a family thing anyway, so not weird at all.” The chubby, blushing younger brother just tapped his fingers against the sofa and thought on it. “What is it like since you said you've done it before and how do we do it?”

Jack holds his brother closer to him, an arm around his shoulder, Tyler pressed against his brother's muscular chest. “Well, it's kind of like having a nice long deep rest. You don't really dream, but its nice and warm and cozy. As for how we do it well… I'll cock vore you then drink a potion to absorb you, then drink another potion to reform you later.” The chubby cario just sat there blushing thinking about his brother diving some guy's cock. “You promise not to like jerk off with me in there?” He shook his head while openly jerking off to harden up for his brother. “No way man I plan to keep you for your full collage break I'm not going, no nut the whole time, besides it'll feel fantastic for both of us. I think we should go ahead and get started, I'll call my friend over to bring some potions while your getting cozy in my balls.”

He gave his younger brother a smug grin, crawling up over him on the couch, cock throbbing in the open air. Tyler felt a surge of lighting go up his spine as a single drop of pre hit his belly, his brother climbing up, getting his fat cock near his face. Jack pulled on his shaft foreskin, pulling back to show off his cock tip right as the slit pulls over Tyler's muzzle. The smell was so intense the heat was incredible and it was so snug just around the tip of his muzzle he couldn't imagine it really taking the rest of his body. Pre running down Tyler's snoot as Jack pumped his hips, thrusting that cock down further and further along his younger brother's face till he finally had to close his eyes. Jack letting out a long huff, grabbing his phone to text his friend to either stop by with the merging potion or if he can't make it, bring by a reformation potion later. Tyler's head poking in completely as his older brother's shaft reached his neck, forcing him to lean forward into that shaft in order to get deeper. Warmth really overtook him, the cock slicking over his shoulder with a wet slapping sound as it clenched and pulled him in.

An overwhelming feeling of relaxation causing Tyler to go limb inside his brother, slipping down inside like a noodle. Squirming lightly as his hips passed inside, cock suddenly slipping inside his brothers. The smell the texture the feeling, it was all so much, he never expected to experience feelings like this. Pushing into those hanging orbs, little foot paws making their way inside, Jack relaxed back enjoying his swollen orbs.

Jack would huff, feeling his younger brother jerking off inside him. It was clear as day what he was doing in there by all those cute motions and sounds. Tyler just hoped his brother wouldn't notice, but he couldn't stop even with his worries, cumming hot strings of warm cum all over himself as he sat in those heavy orbs, knee-deep in bubbling ball butter. All the while Jacks friend brought over the potion in question, a charmeleon that was jacked as hell clear he was only in his second stage by choice at this point. “So who's the lucky guy, your taking care of Jack?” Jack blushed lightly, still hard cock dripping before taking a very quick swig of the potion his friend had given him. “Well, my brother wanted a method to bulk up fast s-so…” The charmeleon just smiled and chuckled. “Oh hehe yeah I get ya my dad did it with me after my 21st birthday, I think I told you the story before I was a fat little charmander at the time.”

The lucario smiled nervously and blushed, holding the back of his head before letting out a hard moan. His cock dripping with pre as his nuts rumbled, his brother's form starting to lose detail, his nuts feeling fatter. Tyler squirmed a bit as it started, he could feel himself sinking into the surrounding walls of ball fat. His brother's warm sludgy cum dripping off him as he sank. Struggling to keep his eyes open, he sank into a deep slumber before becoming his brother's balls fully. The charmeleon poked at those fattened nuts, feeling them up without even asking, knowing his friend well enough to know it's cool. “Damn, he added a lot. You plan on keeping him all to yourself, or plan on reforming him?” Jack had failed to mention in the ritual if fathers viewed their sons beyond saving, they'd keep them indefinitely, figured he'd just freak out if he told him. “Nah, I'll bring him back before his school reopens, hehe as tempting as it'd be to keep him all safe and sound with me.”

He runs his fingers along his hefty orbs, feeling them churn and prep a hefty load. “Damn little bro, just going to start working right away on loads, huh? Fuck you must be making me a ton, these things are getting heavy already.” He smiled up at his friend, the charmeleon blushing lightly just thinking about the situation. “Well Ron, want to help me break in my brother with a quick fuck to unload a little?” The charmeleon blushed at the bold request before shaking his head. “Nah mate, last time we fucked when you were half this horny you kept me all night and pumped so much inside me, I gained six pounds.” Jack jerking off leaned back, letting those musky orbs hang between his legs. “Yeah, but I worked ya so hard you lost ten, it's a net positive.” Ron just chuckled, starting to walk off sassily waving his flame around behind him.

“Just head by the club later if you need a fuck heaven knows half the guys in there pop a boner the second you walk through the door.” His friend walked out on him, he could just head over to the club right away but could he really tell his boss he couldn't make it because he's too horny. His balls sagging lower, the things felt like they were getting heavier by the minute, damn his bro made him productive, he didn't know if he could manage this for a full week. Walking into the bathroom, he takes a nice long look at his orbs, the fuckers were the size of melons now. His cock throbbed, pre sputtering out. Hopefully it was just cause of the initial merging, and he could just dump a quick load before he had to go in.

The lucario running his paws along his hefty shaft in the shower, pumping up and down, though it didn't take much to send him over the edge. He just really needed to get this load out as gallons of sloppy ball sludge splattered along the inside of his shower, emptying his hefty orbs down the drain, the muscular lucario nearly knocked backwards from the force. Balls now the size of grapefruits still massively oversized, but he expected as much before taking his brother. Luckily his nuts seemed to calm down and after a quick rinse to get the smell of cum out of his fur he got into a speedo with a bit of a struggle and started his drive to work.

Jack felt every bump and jostle with his balls, they felt more sensitive than normal, must be because of the extra size. He'd tried growth potions before, and they had a similar effect, he just hopes they don't stay so sensitive all week. The work day goes pretty normally for the first few hours, instructing guys and gals on stretching and helping them build strength and mass. But a little into the fourth hour, his balls starting to sag, he could feel it lust building in his body it was slow at first, so he tried to ignore it. It only speeds up though, having to hike up his speedo throughout the day, folks pointing out the ridge of his cock is showing because his balls are getting so heavy. The speedo starting to stretch until he hits what he could only describe as horny event horizon.

His speedo all but busts, stretching, and his balls instead of growing with cum every few minutes start gaining heft by the second. He has to sprint to the bathroom and get his clothes off just before those orbs bust them. His balls were almost watermelon sized again. His last load flooded his shower, he couldn't do it cleanly in the toilet. Grabbing a few paper towels he tries to do something to cover up but any makeshift clothing he can make is quickly outgrown. It was only going to get worse if he waited, he needed to just bite the bullet and clean up best he could afterwards. He stumbled trying to walk forward into the stall, his clackers were so heavy they were a work-out by themselves.

The bathroom had overflowed with the sound of churning, sloppy cum. Nuts now reaching a critical state, suddenly expanding to bean bag chair status slapping down on the floor. How the hell did his friend deal with this for a full month with him. Grunting, he started pumping his shaft as his balls continued to swell. He pumped as hard and fast as he could, no time to just enjoy a quick wank, otherwise he'd bust so hard he'd flood the whole gym at this rate. From the outside, it sounded like something in the plumbing broke as Dozens of gallons pumped out in a single hot rope and dozens of ropes fired from his cock. Over the course of five minutes, he must have flooded the bathroom with enough cum to fill a swimming pool. His balls were still too huge to wear, his speedo sagging near the floor, entire body head to toe soaking in spunk. The whole bathroom dripped and oozed the lucario just thanking Arceus it was illegal to fire someone over hyper issues. He walked out, no sense even trying to cover up cum flowed and pooled just outside the bathroom as he walked off to his car, waving over at one of his coworkers. “Can you tell the boss I had an accident in the bathroom and headed home early to deal with a new hyper issue?”

A Chatot in a speedo just nodded as Jack made his way out of the building. He grabbed his phone from his car and texted his friend. He was going to need that second potion today, he could already feel his balls starting to prep another load. Thankfully he managed to get home before they started to grow, his friend lived close by, so he was already waiting for him. “How the hell did you do this for a full month with me?” Rom smiled, handing him the reformation potion. “Well the effects change person to person with this potion, clearly your brother has a lot more potential for growth than you if he puts in the effort or if he just stays as nuts, heh. I got a text from Dave earlier saying you walked out of the bathroom after totally flooding it and your boss was pissed.”

Taking a few sips, he stepped inside before guzzling the magical liquid. “Yeah, I hope he didn't take out his anger on him, I asked him to tell the boss for me.” The charmeleon smirks watching his friend's nuts start to glow and shrink before, with a poof of smoke, Tyler pops back into the world on the floor. Soaking in the smell of his brother's musky balls, both of their balls had grown to the size of grapefruits now, though Jacks were still a bit larger than Tyler's. Tyler looked up at his brother soaked in cum the fat cario feeling full of energy after a few hours as his brother's warm balls. “Wow that felt like a few hours at most has it really been a week and oh… You're, uh, very messy…”

Tyler chuckled nervously as his brother pulled him up off the floor, getting cum on his paws. “Y-yeah, well it was only a few hours, seems I couldn't quite handle the size haha. Anyway, I think you have enough for the both of us in you now, so let's spend the rest of the day working on your body… After I take a quick shower… Join me, you're pretty musky.” Tyler let himself be dragged into the shower by his older brother he did smell pretty bad, well it was good, but it was intense. Jack eagerly helping him wash himself because he insisted on helping since they just reformed. “B-big bro I was thinking I know a good exercise, something we could do in the shower maybe?” Jack cupping Tyler's balls, helping wash up his fur everywhere he could, going for the intimate area's first. “Hehe sure, what's your idea?” Blushing brightly, the younger lucario let out a huff as his brother thoroughly helped wash his shaft. “Fucking provides a lot of exercise, you know.” Looking at Tyler, totally dead pan “Dude we're brothers, that's gross… Just fucking with ya but not right now, I just blew a load strong enough to blow the doors off Fort Knox, I'll let you ride my dick later bro.” Once again, Tyler blushed brightly, hugging his brother as tightly as brothers with spikes coming from their chests could hug.
