Don's fingers drummed along the coffee table as he waited. He'd received a text from his older brother not too long ago about wanting to visit, which he wholeheartedly endorsed as they didn't get to catch up as often as he would've liked. What the reason was didn't matter to him as he always welcomed the opportunity to see the other raccoon.

Everything that day happened to work out in his favour as well. His job was able to be done from the comfort of his own home, so he only had to leave the house when he wanted to; any personal obligations he had that week were already taken care of; and his car was in the shop, so it wasn't like he was going anywhere fast as it was.

Anticipation had him sitting there, expecting to hear evidence of his brother's arrival soon. It made him wonder if he should've been doing something else in the meantime.

And that's when he heard a knock at the door. Instantly his head swiveled to the origin of the noise, his eyes lighting up as he jumped out of his seat. His long legs helped him bound over to the foyer in what felt like a fraction of a second. A flick of a wrist opened the door, revealing... a musclebound titan, pretty much about as tall as his waist, staring up at him. He had no idea what exactly he was looking at, only to see some familiar details about the fireplug the longer he gawked - like how the fur stretched over those grotesquely huge muscles matched his, or how he slowly recognized the face nestled in between pecs the size of car tires, and-- "Rigbone?"

The deafening silence that greeted him when his brother opened the door had Rigby a bit embarrassed, but he still did his best to paint a smile on his face. "Hey, Don, it's me."

"You're looking good there!" If there was one thing to describe Don as, it'd be unflappable. Very little seemed to faze him, even when what his eyes told him flew in the face of conventional reality, though he was well aware that it was far more malleable than it had any right to be.

"Uh, thanks," Rigby said, his lips slightly pursing. To date, his brother was the only person besides Mordecai that had any sort of moderately positive reaction to his swollen appearance, though he was grateful most were indifferent.

Don was just happy to see the other raccoon again after some time apart. "Come on in," he beamed as he stepped aside.

Rigby was about to enter the way he normally did for years, only to then remember the trouble he had navigating the door frames in the park house; the last thing he wanted was to damage anything his brother owned. The one thing he discovered actually helping a ton was to squeeze through sideways, though even that had middling success at times given that most entryways weren't meant for someone of his tremendous size.

Don was all smiles as he closed the door behind his older brother. There was one thing on his mind, however. "Hold on, before we do anything else," he said as he held his arms out to each side, "gimme some sugar!"

Rigby's first instinct was usually to protest what he felt was a ridiculous gesture, but he came here for a reason and wasn't interested in getting off on the wrong foot. "Eh, sure, why not." In spite of his short stature, the hug felt wildly different than it normally did given his astronomic increase in size. The surge in strength he gained from his engorged muscle mass led him to apply significantly more force than either he or his brother anticipated.

"Woah, you've gotten really good at this!" Don chuckled as he embraced his brawny brother. The difference in both appearance and power that the other procyon possessed didn't bother him one bit, even if it signified he wasn't the strongest of the two of them anymore. "You're really living up to being my 'big' bro, huh?" He let go of the shorter man. "You started working out recently?"

Rigby rubbed the back of his bull neck. "Uh, no, I haven't."

"Oh, so you've been going for a while now then? Nice!" Don cheered his brother on. "Consistency is hard, but I'm sure you figured that out already."

"No, I haven't gone to the gym since, well... high school, which wasn't that long ago, if you remember." Having issues trying to outright say what caused his fantastic growth had Rigby annoyed. "I didn't get this huge from exercise."

"So that just happened to you one day? I told you being short wasn't the end for you!"

It was at that point Rigby slumped his boulder shoulders forward, frustrated that he couldn't get much of a word in edgewise through his younger brother's constant optimism. As nice as it felt to know the taller raccoon always had his back, the endless positivity definitely wore on him.

"Okay, so what brings you about my humble abode?"

"Uh," Rigby's mind was too scattered to form any coherent thoughts, the purpose of his visit lost amidst the welcome he was given, "this might be kinda... a lot, I guess?" He struggled trying to piece together how best to describe the reason for seeing his brother in a manner that would sound somewhat rational.

Don shrugged. "That's fine, you take however long you need."

"I just..." The mounting frustration coursing through Rigby culminated in him scrunching his hands into fists, though a deep breath helped unclench the tension built up through his body as well as clear his mind enough to form complete sentences. "You know, you've been super cool to me over the last several years and I just wanted to pay you back for that. I wanted to do something nice for you."

"Aw, Rigby, you didn't have to do anything! I just like being able to help out when I can," Don took a knee beside his brother, hand resting on easily the biggest shoulder he'd ever seen in his life.

"Well, it's not just anything. I thought it'd be something you might enjoy."

Don's curiosity was piqued. "Alright, what is it?"

"It's, uh..." Rigby's mind blanked once more, his perfect explanation vanishing and leaving him to think on the spot. "Sorta this," he gestured to his incredible bulk, hands hovering right in front of his heaving chest.

Hearing that had Don cock his head in confusion. "Your gift is... yourself?"

Rigby sighed. "No, it's, you know," now he gripped his pectorals, his fingers conforming to the solid ridges formed by so much beef piled onto his short frame, "the muscles."

That only perplexed Don even more, whose jaw fell slightly agape as he pondered his brother's intentions. "I don't think I'm following what you're saying here."

"UGH! This was what I wanted to get at earlier," Rigby groaned as he palmed his face with a hand. It was then he decided it was best to simply show the younger raccoon the nature of his visit, producing in his hand the ring he brought with him. "The reason I'm as big as I am is because of this."

"Oh cool, nice ring!" Don admired the trinket in the shorter man's hand, noting the brilliance of the large, chiseled emerald smack dab in the centre. But there was something that stuck out to him, something that didn't quite make sense that he couldn't wrap his head around. "Wait, why did that thing make you huge exactly?"

"Oh, dude, I got no idea. Me and Mordecai dug up pirate treasure and this thing was part of it." The light from the large window beside Rigby bounced off the green gem. "Long story short, we discovered what the ring could do and now we look like we live in the gym."

"Mordo's big too? You guys really hit the jackpot!" Don laughed. "So what does this have to do with me then?"

The further Rigby got closer to revealing the purpose for his visit, the more he mentally squirmed. "I, uh, thought you might want to try it for yourself, you know? I figured you might be interested." That was the final straw; he couldn't keep up the charade any longer. "Okay, that's not the reason. Mordecai and I were fooling around when he joked about you looking like me and that you'd probably wear this kinda size as well as I did, and then I laughed, but deep down I kinda sorta didn't hate the idea," his cheeks burned red with embarrassment, and it led to him chastising himself that he didn't consider what his brother might've thought about the whole thing. "I know it's a selfish reason and I'm sorry, and if you want me to leave I'll--"

"Hey, I'm not upset."

Hearing the other man not admonish him as much as he was doing himself had Rigby's eyes light up, whipping his gaze in the direction of his younger brother. "You're not?"

Don could only grin at the shorter procyon's reaction. "No, you wanna include me in stuff you like. Why would I be upset?"

Rigby still couldn't believe what his ears told him. "Even if it's something as weird as this?"

"Would you have gone to dad to do this?"

"Oh god, absolutely not!"

Don slung his arm around the larger raccoon's burly shoulders, his smile stretching from one ear to the other. "See? You want me to be an active part of your life; I'm thrilled you thought of me!"

Rigby wasn't one to look a gift horse in the mouth and accepted that his brother was genuinely thankful. "I'm honestly glad you're taking this so well."

"Eh, I'm just considering this as kind of a throwback to last year's Christmas party," Don shrugged.

The connection to an event he thought was supposed to be mundane had Rigby's heart nearly stop. He had no clue what the other raccoon was talking about. "Wait, what now?"

"Yeah, you had your hands all over me that evening and were all around super cuddly. I thought it was really sweet!"

"I don't remember this at all," Rigby mumbled into his hand. He racked his brain trying to identify why it was he couldn't recall the night in question, with one possible explanation out of hundreds seeming more and more likely the longer he dwelled on it. "Wait, was that the party where I was blackout drunk?"

Now it was Don's turn to think, though that didn't last long as evident by the way he gasped. "Oh yeah, I think it was!"

Thoughts of what might've happened that evening swirled around in Rigby's head, panicking as he had no idea what really occurred. "I didn't do anything in front of other people, did I?"

"Nah, I brought us up to my room. I wasn't about to let you embarrass yourself."

Rigby then narrowed his gaze at his brother, his concern still unwavering. "We didn't do anything that night, did we?"

"No, I couldn't let anything happen, not while you were intoxicated," Don patted the older procyon's shoulder. "Plus you passed out a couple minutes after we were alone anyway. It was really cute."

Knowing his brother had enduring support for him had Rigby grateful, twisting his mouth into a warm smile - something that few people were able to accomplish. "Thanks, Don."

"Of course, anything for my big bro!" Don then inspected the older raccoon's physique, wondering what having that level of musculature felt like. It must be intense on such a short frame! "So, what's all this like anyway?"

"Oh, dude, it's awesome! I can lift a whole bunch of stuff that not even Skips can and carry it across the park like it's nothing." The bulk across Rigby's body tensed in excitement, his fists clenched as his heft flexed nearly twice as large. "One time some dude rolled into the park in his hummer and was all rude and stuff, and I just picked it up and chucked it back on the street with him in it! Oh, and then there was this other time where--" His train of thought derailed when he heard a faint snickering coming from his younger brother, his nose crinkling in irritation. "What's so funny?"

While it wasn't his intention to halt the other man's retelling of the story, Don couldn't help himself from enjoying the enthusiasm of the shorter procyon. "You know, it almost feels like nothing's changed at all."

It was Rigby's turn to arch a brow. "What do you mean?"

"It doesn't matter what happens to you, you're still yourself. I love that about you." The authentic demeanour that Don naturally held was on full display, seeing that his older brother felt the love. But about what was said earlier... "So, the ring?"

"Oh!" The sudden mention of the trinket nearly made Rigby fumble it, though he managed to catch it before it hit the ground. "You wanna?" He gazed at his brother with a hopeful twinkle in his eye.

Don wryly grinned. "You came all this way, right?"

"Awesome!" Rigby would've jumped a foot from the floor were he not hundreds of pounds of rippling raccoon beef. He hastily slipped it on a finger, his attention on the gem while he directed his brother. "Okay, you're gonna wanna find some room."

Don scanned the area around him, stepping back from the shorter man and hoping there was enough space to work with. "How's this?"

Rigby's smile took up half his face as the anticipation of what was to come flooded his brain with exciting images. "That's perfect!" Without so much as a warning he twisted the ring in the direction of the other procyon, a dazzling beam of light shooting from the emerald and illuminating the taller man. His chest heaved as he awaited what the power of the gem would bestow upon his younger brother.

It felt to Don like barely a few seconds had passed, but being overcome by a blinding ray of green made those few moments feel like whole eternities; a little notice would've been appreciated. Fortunately it didn't last forever, though he still needed to rub his eyes to get rid of the spots that had taken over his vision.

And it was only when his sight returned to him that he realized what his brother was getting at earlier - he had genuine muscle mass now.

While he had veritable definition before, it paled in comparison to the size he attained in a matter of seconds, especially evident in his chest, which he could now see whenever he looked down. It shocked him in their sudden appearance, his hands investigating and discovering how firm they were from a few errant gropes; he kinda liked how they felt - kinda really liked it!

That wasn't the only thing he checked out. His arms themselves had blown up, bulging far more than the noodly limbs he had mere moments ago, giving him the look of someone who worked out part-time. The feeling of his biceps flexing to show their multiple heads had him amazed. He had no idea that was even possible for a person to achieve, let alone that he'd done so without trying. This was cool!

Those legs of his also followed suit, thickening far greater than what he was accustomed to. Standing how he normally did meant his swollen quads touched one another, causing him to shift his posture to better make room for his beef. He felt so powerful, like he could kick a door down! Cyclists might get envious of him now.

"Aw, dude," Rigby whooped when he saw his brother's transformation, "it worked like a charm!"

"Dang, Rigby," Don's eyes were wide as he looked over himself, his fingers trailing down his newly chiseled abs, "you weren't kidding when you said this was awesome!" He couldn't kill the enthusiastic grin plastered across his face if he tried, not that he wanted to. How could he actively hate the sensation of being so huge? He wouldn't dream of it!

Rigby, too, admired the heft that had been thrust upon the younger procyon, his own smile beaming. True to his nature, his hands were all over the taller raccoon, fondling whatever beef he was able to get his mitts on. The sight of his brother looking similar to how he did after his first blast got him going far more than he initially thought it would. He was about to ask if maybe a little making out was in the cards, but a discovery below the belt grabbed his attention far faster. "Hey now, looks like we're not alone."

Don cut his revelry short to see what the older raccoon was talking about, observing right away that not only was his endowment out on display for the world to see, but also that it was rock hard, stiffer than it'd been in ages. "Huh, would you look at that!" Normally he'd hide his erection to maintain modesty, but he didn't feel the need to now.

What looked like a foot of turgid raccoonhood had Rigby utterly entranced, his eyes squarely focused on the throbbing log of meat. Seeing it did pop a question in his head, however. "Dude, were you always this hung?"

"Uh," Don ran a finger along the length of his aching shaft from tip to base, "not quite to this degree, but yeah, I have."

"Oh dude, I was too! Mordecai never had us do dick-measuring contests to settle stuff for that reason."

Don could only chuckle at the older procyon's excitement. "I can see why," he pointed at his brother's meaty schlong, leaking a steady stream of pre, "that thing's huge!"

Rigby followed where the other raccoon's finger was aiming, his eyes growing wide when he saw how much he clearly enjoyed the muscly visage of his brother. "Oh, uh," there wasn't any way he could hide his hog, even if he wanted to, "yeah, I'm kind of a big boy." It was then that he noticed the taller man's pole pulse before dribbling a thin rivulet of pre down the flesh to the orbs supplying them. An idea then popped into his head, one that he knew they'd both enjoy. "You know, I could help you out with that if you want."

While Don liked the sound of his member being played with, he wondered if the shortstack might be biting off more than can be chewed. "That's not too much for you to handle?"

"Please, I've got loads of experience with dicks these days. I can take care of that no problem."

"I can't say I've had a whole lot of encounters with men in the past, but," Don positioned himself against the sofa, his dimpled glutes leaning on the arm rest, "be my guest."

Rigby mentally cheered when he witnessed his younger brother let him take the lead. "Dude, trust me, you're gonna love this!" He hastily bounded over to the other raccoon, his lumbering steps making the hardwood squeak as they were never rated to casually support the weight of someone as monstrous as he was. His hands instantly worked over the taller procyon's inner thighs, eliciting whimpers of pleasure that indicated how good of a job he was doing. He knew right away this wouldn't last long.

Fingers clutching onto the soft fabric of the couch, Don had no idea how sensitive he was down there, not sure if that was natural or a product of his growth. "D-Damn, Rigby, you sure know how to please a guy," he bit his bottom lip as the other raccoon's ministrations sent shivers of euphoric bliss ripping up his spine.

"Bro, you ain't seen nothing yet." True to his word, Rigby didn't intend to solely play with his brother's legs. Nestled in between the taller procyon's quads were his engorged pecs, necessary as there wasn't any other way to let that tumescent cock near his face. He huffed in approval as he inhaled the other man's musky scent, inhaling the aroma as he nosed along the flesh, letting his tongue gingerly lap up the precum drooling from the tip. The slight graze of his teeth across the mushroom head coaxed out a moan, putting a wry grin on his face.

Don found it hard to vocalize his feelings. The intense stimulation coursing through him had his muscles tensed involuntarily, his eyes struggling to stay open as his breathing quickened. He hissed through gritted teeth as the tongue of the other raccoon carefully trailed up his throbbing pillar, each trip going from base to tip. He'd never been with anyone who could make him feel as good as what his brother was doing now!

The way that rod leaked out more and more preseed told Rigby his younger brother hadn't gotten off in a while, which didn't bother him at all. With a smirk he lapped along the meatlog until he got to the tip, where he then took the entire thing into his mouth, feeling it push into the back of his mouth and stretch his throat. That might've been something that intimidated him in the past, but the multitude of times he'd sucked the blue jay off honed his skills to the point where a dick nearly a third of his height didn't faze him in the slightest.

"Ah!" Don gasped when he felt his crotch rocket be enveloped, taken in by the masterful mouth of the muscle monster that was the older raccoon. Every trick in the book he'd learned was in use - from teeth lightly scraping his sensitive flesh, to his balls being fondled - and it had him feeling hornier than he'd ever been. He snorted as production of pre skyrocketed, his taint bulging as he neared climax. The other procyon wasn't even bobbing all that fast and yet he felt ready to blow.

And then he did.

Salty spunk shot down Rigby's greedy gullet as he mashed his face into his brother's musky pubic bush, the heady scent of the masculine raccoon a tad overpowering as he tried his damndest to not let a single drop of cum spill. Every breath he took deluged his nostrils even more, to the point where it was the only thing he sucked in for several long seconds. A part of him noted a similarity to his own smell; that just roused him up even more.

Don's chest heaved after practically exploding into the other procyon's mouth, rubbing his face with a hand as he tried to collect himself. Barely any time had passed and he'd already busted the biggest nut in his life. He had to hand it to his older brother, this was something he had a lot to learn in.

Feeling the end of the younger raccoon's output got Rigby to pull his head back, freeing his brother's magnum dong, a string of saliva connecting it to his tongue. He took a moment to adjust his lungs to fresh air again after burying his nose in one of the muskiest parts of the other man's body. A lick of his lips wiped any remnants of seed from his mouth, which gave way to a cocky smirk that he often wore after getting someone off. "Hm, hm, hm, hm, hm!"

"I did well, I take it?" Don chortled at the way his older brother reacted.

"Bro, you did great! You're a natural." While sucking the taller procyon off certainly got them both feeling good, Rigby knew it could feel a whole lot better in a matter of seconds. "Wanna have another go?" He flashed the ring at the other man.

"Oh, I can?"

That got Rigby laughing hard, his face mashing into his bouncing chest. "Dude, there's no limit on this thing! You could probably get as big as you want to."

"Then fire away!" Don laughed. He might've thought the concept of a ring that made someone bigger rather odd at some point in time, but now he couldn't get enough of it. More size was welcome now!

Rigby did as instructed - not like he wasn't going to as he was the one who put forth the idea in the first place - aiming the trinket at his younger brother, a lascivious twinkle in his eye as he could only imagine the outcome he would witness. So far the blue jay's assessment was correct in that the other raccoon looked remarkably like he did while gaining muscle, so much so that he intended to skip the incremental steps and blast his bro with enough beef to make them match. Yeah, okay, maybe proportions were awesome after all.

The second dose of light lasted much longer than the first, with him waiting with bated breath at what the taller man would turn out like. His leviathan hog stood tall as he pictured the towering visage that the other procyon would now possess, oozing preseed at a rapid rate. Eyes trained on the illuminated figure, his breath caught in his throat when he shifted the ring in another direction; the moment of truth was upon him.

A few blinks were needed for Don to readjust to the level of light in his house, having to rub them to bring his vision back to normal. That's when he made the discovery of a lifetime. "Woah!" He gasped loud enough for anyone in the place to hear him, not that he cared at the moment. "You weren't kidding when you said this thing had no limit!"

Right in front of his nose was his chest, far surpassing the massive size he thought it was before, now a permanent fixture of his sight regardless of where he looked. The overwhelming heft hanging from his upper torso had him perplexed that he hadn't succumbed to the weight, though the momentary lapse in rationality gave way and let him realize that the immense musculature came with the strength necessary to wear it all.

And what strength he had! In his slight moment of exploration he inadvertently pushed his sofa without even noticing - a couch that normally needed two people to move relented from just a simple shove of his oversized legs. There was so much going on that he almost couldn't keep track of it all!

It was then that he took sight of his arms, his eyes going as wide as saucers when he got to observe the utter enormity that they'd become. Split-peak biceps bigger than his head at rest nearly doubled in size from a mere flex, effortlessly making the tires on his car look puny in comparison. That wasn't to mention his triceps, more than twice the size of what his limb used to be and blasting out four times as huge when in flexion. So much might had been bundled up in his arms that he felt like he could overpower heavy machinery, maybe even putting forklifts out of business. That wasn't exactly what he needed as an accountant, but any skills gained were always good to have!

While he had no possible way of seeing it, his back had also benefited from the tremendous expansion of his frame, able to be felt whenever he rolled his shoulders. Densely-packed raccoon bulk that weighed more than he used to piled onto every muscle group he had. Traps he thought were huge on bodybuilders were now outclassed by his own, rising high above his delts and taking up whatever space next to his head they could. His lats were no different, flaring out wide like wings, potentially broad and flat enough to park a golf cart on. He couldn't believe this was all him!

But his revelry regarding his torso didn't stop him appreciating his legs. Quads thicker than his body used to be positively erupted with striated beef, giving him inevitable comparisons to the trees outside, only those trunks didn't quite stack up to the mighty pillars that supported him. The utter immensity stuffed under his brown-furred pelt immediately captured his attention in how much space they swallowed up, widening his stance considerably to the point where his thighs lined up with his shoulders.

"Dude, you look awesome!" Rigby practically leapt off the ground as he watched his brother examine the newfound bulk stacked along that gorgeous form. Like him, the other procyon had surpassed the ideal ratio - that being height equal to width - and now sported a physique more becoming of them, at least in his perspective.

He ambled over to the awestruck raccoon, his heavy footfalls sounding out throughout the room, and let his hands roam around the sumptuous heft of his brother. Rock-hard bulk couldn't be contained by a single one of his appendages, but that didn't matter when he got to grope it all for himself. His brother really did end up looking like the spitting image of him. It had him wondering if that meant all the things that he enjoyed were transferred, and he couldn't wait to see for himself.

Sensations of his older brother caressing his prodigious musculature induced a moan out of Don, one involuntary that had his fingers curling. The shorter man was relentless in the onslaught given, feeling over whatever was within reach. Everything from his heaving pecs to his bulging legs had been fondled, and yet he felt like that wasn't enough. His body craved more.

"Rigby," Don grunted through gritted teeth, "keep going."

"With pleasure!" Rigby didn't need to be told twice, his attention now square on the absolute goliath of a cock his brother now owned. His fingers traced over pencil-thick veins that throbbed with need, making the turgid flesh look like a lewd road map. The precum that now coated his digits far eclipsed the volume of seed he'd just consumed; his brother was a mass monster now!

The heightened sensitivity that came with Don's body nearly had him doubling over as relentless ecstasy pummeled his body. "Wait," he moaned, his hands weakly pushing the shorter procyon away so that he could spin around and crumple over the armrest of his couch, eliciting a groan from the furniture as it hadn't supported that kind of weight before. His intentions were clear, especially as he raised his tail to his older brother. "Go for it."

What had to have been the thickest set of ass cheeks the world over stared Rigby in the face, who couldn't stop his own endowment from pulsing at the notion of the other raccoon's desire. "You sure about this?"

"I don't do this for just anyone," Don stated. "Takes a real special guy to make me wanna bend over, and you're that man, Rigby."

Hearing that turned Rigby on even more, his own chest rising and falling with every heaving breath he took. Wordlessly he descended upon the other man, his hands gripping onto their own dimpled glute, feeling the incredible sensation of bulk in a rear end capable of crushing vehicles. His mind ran wild with longing, so much so that he managed to cut his groping short in order to part each cheek and shove his face right in between.

His lust for the other raccoon fueled his actions. Every intake of air was permeated with masculine musk, inundating his brain with the heady scent and sending his tongue lashing over the winking pucker into a frenzy. He relished in how _manly_the younger procyon was, giving him a taste of what a fit of passion with himself might end up like. The thought of which had him belch forth a glob of pre.

Don, meanwhile, could do nothing but accept the assault from the fireplug, his face twisting in pleasure as he bit his lower lip. The fervent tonguing of his tailhole had him bury his face in a pillow, not used to how fantastic getting eaten out felt. His older brother really was a pro at this now!

Not able to prolong his urges any longer, Rigby resurfaced from between the mounds of beef, sucking in fresh air for the first time in moments. His cock felt like it was about to erupt. "Now to--" He paused when he instantaneously noticed a problem - his dick couldn't reach the other man's ass. It caused him to think on the spot for a solution. "Hang on." He bolted out of the room, rummaging for something in the kitchen, eventually bringing back a stool with which to stand on. A part of him said he should've tested whether or not it could hold his weight before hauling it back to the couch, but that came immediately after he discovered that supporting him was no problem at all. He made a note to ask who his brother's furniture manufacturer was as that was becoming a growing issue around the park house.

Finally, he could proceed, slipping his throbbing raccoonhood between the globular slabs of meat and guiding the tip to its destination. The copious amount of precum slathering the quivering hole added to the lubrication provided by his tongue, allowing the tip of his mighty hog to carefully stretch open the other procyon's rear entrance. Both he and his brother groaned from the sensation, each mentally begging for more.

Getting more and more stretched out had Don's toes curling, his mind reeling that someone half his height was taking him from behind. Every inch plunging deep into his virgin asshole forced a longer and louder moan to rumble from his throat. He could feel his hips be grabbed by his brother, used as a means to position against him better. It seemed like the shorter man was shoving a goddamn telephone pole up his chute, friction non-existent thanks to all the slimy pre coating his inner walls, but with resistance still a thing as his inexperienced rear end didn't open that far. And this was normal for the other procyon?!

His urge to let the older raccoon pound him skyrocketed the more of that girthy schlong he took. His brother's swollen pectorals rested on the small of his back, the weight of that meaty chest unable to assail his own engorged muscle mass in spite of how much pressure was applied. But the fondling of his overmuscled ass hadn't abated in the process of being speared by what he assumed was the world's thickest cock, chalking it up to the shorter man using his cheeks as a means to surge arousal. He didn't mind at all, in fact he encouraged it, evident by how he pushed back, forcing more of that pillar inside him. The intense gaping that caused him contorted his mouth into a particularly goofy grin.

Rigby nearly faltered in his approach when he felt the rest of his crotch rocket be taken into his brother's anal cavity, the clenching on his shaft sending shockwaves of pleasure rocketing through his shortstack body. He hissed in approval as he began rocking his body against the solid glutes of the other raccoon, building up a pace that gradually spread that pucker open even wider. It brought back memories of his first time and how much he enjoyed being on the bottom.

Which is why he had an idea of how to make this an experience his brother wasn't soon to forget. Fucking the tight hole of the taller procyon was one thing, but the act could be so much more if other parts of the body were involved. His hands migrated around the writhing bulk of the brown-furred behemoth he'd impaled, reaching far enough to grab hold of the other raccoon's pecs and finding purchase on those fat nipples. He gently tugged and squeezed them as his pelvis continually slammed against that hypermuscled ass, twisting them like he would a door knob; it was something he liked being done to himself.

Don had no idea how much he adored having his thick nips played with, his form slightly falling limp as pleasure jackhammered his brain. He moaned into the pillow in his grasp, the feeling of his brother's wrecking balls slamming into his own testosterone factories jumped his arousal up a level with every strike. They churned with potent seed, waiting to unleash his load, but he didn't want to be the first to blow as he came not too long ago. No, he'd try to hold off as best he could.

Which was easier said than done. Not only was the feisty fireplug manhandling his pecs but he also felt his swollen lats being tongued with wild abandon, the shorter raccoon insatiable in worshiping his size. It seemed like he didn't need to do anything! Not that he could as the euphoria coursing through his veins made it difficult for his limbs to do much else than flex uncontrollably. He'd have to think of something to do to repay his brother for making him this gigantic; it had to be something big.

More and more Rigby's rod was clamped down on, which simultaneously got him to momentarily stop as well as spur him on to thrust harder. His bucking became ardent, drilling into the other beefcake as if piercing the ground to look for oil. He did his best to keep up his pistoning even though he could feel climax rapidly approaching. If there was one thing he had to give to his younger brother it was that the other raccoon lasted far longer than he thought would be the case. The towering hulk was a pretty fast learner!

And that was having an effect on him. The harder he fucked the other procyon, the more resistance he got in return, which culminated in his breathing hastening as orgasm neared. Like all the times he'd railed the bird back home, he found his face buried in his pecs, his own intoxicating scent filling his nostrils and only making him hornier. He wanted to keep pace, but his body said otherwise.

This was probably the best idea he'd had in ages.

Don was no stranger to what the older procyon was going through, knowing the telltale signs of release on the horizon. It prompted him to act up as his brother's resolve was wavering. The slowing down from the other raccoon emboldened him to keep the tempo going, pushing back against the shortstack's shredded pelvis with his own bloated glutes to continue getting nailed. It had the effect of further flattening his prostate and melting his mind.

While he thought he'd be the first to blow given the immense euphoric bliss inundating his trembling form, the muffled cry in his mountainous lats signaled his older brother couldn't handle his aid any longer. In seconds the other procyon's cumpipe bulged greatly with virile raccoonbatter, utterly deluging his inner walls with pearlescent cum and filling his guts like they'd never been before. "Yeah, that's it, bro, gimme all you got!"

Rigby did just that as he kept his crotch flush with the swollen mounds of beef that his brother possessed. He could barely vocalize his desire to pump his overwhelming load into the behemoth, only able to inhale the earthy aroma coming off the taller man's back as he buried his nose as deep as it could go between the incomparable peaks of musculature.

His hands stopped their assault on the other raccoon's hypermuscular chest, only holding onto them as he drained his balls into the awaiting cavity of his younger brother. There wasn't really much in the way of measuring his loads back at the park house, but his routine experimentation told him the bathtub was insufficient to contain his robust output. To think he was busy jettisoning that into the titan of a procyon, but it had him wonder if the taller man could take it all. If he could get balls deep without complaint, then the answer was probably yes.

And it seemed like a chain reaction had been started in the other colossus. With a low, loud moan - in which he was able to make out his name - the hulking raccoon bent over the sofa blasted what had to have been a load even bigger than his. That made sense as his younger brother's cum tanks ended up fatter than his were, likely because the taller man's body had the room for it. He couldn't stop himself from wanting to feel all that spunk being geysered into him, his mind racing as he pictured himself underneath the other titan. Maybe they'd spend even more time together than he initially wanted to.

What felt like whole eternities had gone by before the pair of raccoon muscle monsters had emptied their balls of everything they'd produced, leaving them in a sweaty heap on top of one another. Well, that was the case for a bit as Rigby's footing on the stool slipped, sending him careening to the ground.

"Woah!" Rigby whooped in surprise. The abrupt shift in his position had his world spinning, not gathering his bearings until he crashed to the hardwood floor below.

The sudden absence of the massive log of raccoon fuckmeat in his ass had Don also gasp, his bulk tensing as the feeling of emptiness in his tailhole overcame him. He seemed to do a good job at packing away the other procyon's seed as very little of it appeared to be pouring out of his abused pucker.

And that's when he realized why he was devoid of dick, having only just then registered the shorter man's fall. "Rigby!" He jumped into action, nearly toppling over himself by being unused to his profoundly top-heavy physique. "Dude, are you alright?"

"Yeah, I think so," Rigby grunted, needing to push himself off his back as he couldn't simply roll over with all the engorged muscle mass encompassing his form. It was after he moved that he realized his tumble had more of an effect than he originally believed it would, noting the very 'him'-shaped crater in the floor. "Uhhh..."

"Eh, that can be fixed no problem," Don shrugged his boulder shoulders. The incredible dicking he received from his brother had him raring to go again, maybe trying a different position or even switching up who fucked who. He slowly grew antsy with need until he happened to glance at the clock, doing a double-take when he recognized how much time had been eaten up by their fornicating. "Dang, I've got a work meeting online I gotta get to right now. How about you swing by some other time and we can try more stuff, hmm?"

"I'm free tomorrow if you are."

"Tomorrow sounds great," Don wryly grinned. "And bring that ring."
