I'm beginning to think that FA: CrashB really likes my work. I dunno what it is. Features size changing antics and taurs. big ones.


Crash had always been worried someone would find out about some of his...larger than life preferences. After meeting and getting to know Thunder and Kaji, the lion-bull had this deep-seated worry that something he did with either one of the two would end up on the news. The idea that he was now acquaintances with a deity of all things still boggled the mind, but the worry never left his head even if Kaji could make everything better with a snap of his fingers. Frankly, it felt a bit off, but he was a nice guy and didn't see the type to be over advantageous with his powers. The worry had finally sprouted into something legitimate when his roommate confronted him with something today.

"So, what's exactly all this?"

His roommate Jake, a rather pudgy polar bear dressed in a graphic tee and shorts, looked at him, his eyes bound with curiosity at the thing in his hands. It was Jake's tablet, but the picture on it was something Crash didn't expect for a long while. It was him, but a lot more of him than usual. Notably, Crash was damn near the size of a three story building in the middle of the forest. He could note out two small dots on the side that were green and black respectively, so the time of the photo hit him like a sack of bricks. He recalled the first time he met Kaji in that pagoda outside of town. Did Jake actually follow him?

"Um...a movie or something? Looks pretty real, too." Crash stammered a bit, eyes darting left and right to avoid the rather big smile Jake had on his face.

"Come on, I'm lazy, but not I'm not stupid. Here I was busting my butt trying to help you make gains last time and you had this up your sleeve?" The polar bear huffed, crossing his arms.

"Which went very bad as well." Crash cut in.

Jake rolled his eyes and continued. "Semantics. But how did you do it, I wanna know, maybe I can help if you're still on that."

Crash was hesitant to answer. Jake was lazy, yes, but the bear was a big nutrition and science guy, which went against his current build which he claimed was perfectly healthy. The belief that magical things existed probably wouldn't sit well with him, so Crash opted for the next best choice.

"Don't know, I had help from a friend, but as you can see, it didn't work out all that well too." He huffed, lying back against his couch. The assumption that Jake would freak out had finally left his system, but he could still hear his heart beating in his ears. "Why are you so curious about this, anyways?"

"Well...I felt kind of bad the first time and figured I could try again with that dragon friend of yours if he's willing. Second time has to merit some results since I kept the first one documented." Jake offered up. Crash looked at him with shock at the mention of a document of the first time that led to this slippery slope, but he was waved off with a white hand. "Maybe we can concentrate it and keep your hybrid butt at a manageable size that doesn't involve bursting out of buildings at a moment's notice." He snickered.

Well...Crash didn't deny that Jake had a point. The major goal at the start of it was to get bigger. While the massive spurts were definitely enjoyable, Crash also couldn't ignore the fact that he wanted a little bit more permanence to his size. The lion-bull was close to six feet and in the few hundred pounds with thick arms, sizable legs that had trouble with pants, along with a stomach and chest that made tank tops a legitimate issue to get off. But after the last few adventures, he always left with a taste, a desire for more. After a few minutes of thinking, Crash nodded in agreement.

"Sure, let's give it a shot. Anything can't be worse than what's already happened." He said to Jake, shaking the polar bear's hand in earnest.

Jake beamed at him and went off into his room once more, but not before Crash yelled out to delete the picture. Just because he trusted Jake didn't mean he trusted technology to keep things a secret for the most part. He then sought off to make a phone call and see if he could call Thunder over for round two. A quick phone call and some light convincing from Crash had the eastern dragon arrive at his apartment in about an hour. When he arrived, he and Jake got to work and comparing notes for something a bit more long term from what Crash was able to tell. The first meeting resulted in a skeleton of what was to come.

"So, we're going to try this out for a full week? No instant results or anything like that?" Crash asked the duo as they sat on the table with notes scribbled out everywhere on paper.

Thunder was the first to nod as he twirled one of his black whiskers between his fingers. "Yup, probably even more if we want to. I'll also be trying it myself so you have company since your roommate doesn't want to step foot into a gym." He smirked.

Jake shrugged his shoulders and slumped back into his seat. "Hey, may as well not ruin what I already got going on."

Crash simply rolled his eyes and motioned for Thunder to continue.

Thunder went looking for a piece of paper that had been written on that detailed most of the process and handed it to Crash so he could get a better grasp of it. From what he could tell of the dragon's shoddy handwriting, they were going to spend at the very least a week, at most a month trying a shake meant to something to his body -he couldn't read the list or didn't understand the words being said- and slowly increase his overall size and weight along with his usual workouts. Thunder said he would accompany him, so he figured that he wasn't going to be alone in trying whatever they concocted.

"Okay, I think I'm getting this. Can you at least make whatever I'm drinking tastes good? I don't want a repeat of last time." Crash grumbled, putting the paper down on the table.

"I...can't make any promises." Jake said with a sigh.

Thunder nodded in agreement. "For real, it's not his fault. Really don't know how to make protein shakes taste good. If I did, I would have done so a while ago."

Crash let out a groan before he left the two to continue their work. At some point into the night, Thunder left with a yawn and assured Crash that nothing would go wrong this time. He went to bed with the hope that Thunder was right about this and would find out in the coming days.

The days whittled by as Thunder and Jake made progress with their planning, leaving Crash in the dark until the time was right. Any time Crash actually saw the two outside of Jake's room, one of the two were getting something to eat, drink, or to use the bathroom which didn't leave a lot of time to press them on details. Finally, everything came up well as Thunder and Jake soon left the room with a massive vat of something. Crash wasn't able to tell what it was, but the two eagerly stuffed it into the fridge for the sake of keeping it cold.

"Okay, so that's done...I think." Jake said, slumping into the living room couch. Thunder soon followed suit, leaving Crash to stand above them arms crossed and looking at the two with a frump.

"You think? That doesn't exactly fill me with confidence." Crash said.

"Don't worry about it. We'll try it out tomorrow when we go to the gym and see what happens. I'm confident you'll love the results." Thunder assured him with a tired smile.

After past experiences, Crash wanted to believe him, but something always went wrong. With a sigh, he simply accepted it and sat next to the two tired nerds and wasted away the night chatting and watching T.V. The next day soon arrived and Thunder was at his apartment at the crack of dawn dressed in a thick hooded sweater and sweatpants with a duffel bag in front of Crash's door. The eastern dragon waved down at him with a smile that only said "early bird gets the worm".

Crash's tired expression only detailed "let me go back to sleep". After close to a minute of staring, he eventually let Thunder inside while he got ready. They could still hear Jake snoring from his room, the lucky bastard. At least he got to sleep until the sun was up. Crash could see the makings of the sunrise as he got dressed and got his duffel bag. While Crash went off to get ready, Thunder went into the fridge to prep the drinks. He pulled two protein drink containers out of his bag, and then pulled the vat from last night out into the open. He scooped a bit of the contents into each shake and promptly shook them before leaving to use the bathroom. When Crash returned to the living room, Thunder was nowhere to be seen. He stared at the vat and the open protein shake containers. The stuff in the vat had a purple color to it and looked more like goop than anything. The hybrid leaned in to take a sniff of the stuff, unable to get an actual smell or possible taste out of it. Hopefully the drinks tasted good.

As Crash leaned in a bit more to observe the mysterious contents that his friends spent more than a week working on, he lost his balance along the table. No thanks to his two left hooves, Crash knocked his elbow against the vat, causing it to spill along the table thankfully, he didn't knock over the drinks, but now he had a mess of purple goop to clean up with! Thunder was still gone, but he had to make this stuff disappear and fast. Rather than contaminate the bigger supply, it made more sense to just dump what was on the table into the shakes. No harm done, right? Crash put the container at the edge of the table, pushing all of the goop into each drink as fast as he could before Thunder returned.

"Please work, please work..." Crash mumbled to himself. He started shaking them firmly to try and let the shake's flavor overpower whatever the hell he just stuffed into there. Once the sound of a flush was heard, Thunder emerged from the hallway. Crash stiffened at the return of his friend before faking a yawn.

"Do they at least taste good?" Crash yawned out as convincingly he could, passing a shake to Thunder and opening his. "Why do you like going in the morning, I'm more of a night guy, yeah." He finished quickly. He stared down at his drink for a few seconds before he saw Thunder down the thing straight. His heart started beating and he prayed to himself that he didn't notice. It presumably went down fine as Thunder finished his shake silently before letting out a gasp and coughed, trying to rid his throat of something.

"Ugh, lumps. And it's chocolate, so take that as you will." Thunder finished, putting his container back in his bag. "Why not take some of it now? It's actually not that bad."

Crash stared at Thunder, then back at his container. With a deep sigh, he chugged back his drink, instantly tasting the artificial chocolate and the goop that slid back his throat. He drank it all the way through before gasping for air loudly. Thunder stared at him oddly before he shrugged it off as nervousness about the whole thing.

The two soon left for the gym afterwards with Crash's complaints about the taste. At least the shake spurred him to life, he felt bursting with energy that he couldn't wait to burn off. However, Crash couldn't tell if the bursting energy was the guilt rising up from his accident or because of the pre-workout buzz. The trip to the gym itself was a quick run thanks to Crash going from a brisk speed walk to a full on sprint leaving Thunder to trail behind. When they arrived, the place was understandably empty since the sun was finally up in the air, signifying normal people to get up to start their day.

During the workout, Crash started with his usual warm up for back and arms; a few stretches and his warm up sets. With the buzz from his shake, he was feeling a bit adventurous. After setting himself up on a rowing machine, Crash just set into a low weight and planned on progressing onto his usual weight from there. As every rep passed him by, the hybrid's body felt like it was going on overdrive. He was itching to up the weight since the blood was flowing way more than he was expecting it to be. His biceps tensed and flexed alongside his chest, his stringer top slowly becoming taut against his furry orange hide. After his warm-up was done, Crash simply went onto his usual weight and focused on the first set. His biceps and chest tensed powerfully as he rowed the weight back and forth in a set motion, rumbling happily at the resistance. That resistance soon began to fade right at the end of his first set. Starting to feel the pump, Crash stacked on close to his bodyweight to try an experiment of his own.

"If my usual felt like nothing, then let's see..." he muttered to himself. He gripped the handlebars of the rowing machine and soon felt the resistance hit him hard and fast. The instant he tried to push, the weight barely budged, but he didn't stop. Veins could be seen pushing up from his orange fur, Crash snorting with every breath like the part bovine he was. His arms and chest burned for more as he finally pushed past the first rep with a heavy pant. And then he did it again, and again. Here he was, pushing more than his max of over hundreds of pounds and it was like doing a warm up! Elation rose up in Crash's chest as he finished off the second set with nary a bead of sweat on his frame. However, he was suffering a pump like he never did before. His arms felt substantially bigger, as did his chest, the tiny strings that kept his tank top together pushed further ahead. He could feel the pump spreading down his torso as well. If this was what it felt like, he wondered how Thunder was doing.

He turned his head to see the eastern dragon in question working on his shoulders with two large dumbbells in each green hand being lifted up and down like they were lightweights. He snarled and huffed during each rep before eventually settling down the weights and shrugging his shoulders and glancing over to Crash.

"Jeez, no need to rub in the size with those peanuts." Crash chuckled. "Though damn, this feels great. It's kind of like I want to take on the whole world and then some." He flexed his arms, the peaks of his biceps rising up slowly before reaching their full size and then some. He wasn't seeing things, his arms and chest; along with the rest of him were slowly getting larger. His tank top fit more like a tight tank and his workout shorts were filled to the brim with his bulky legs. He'd only worked out one body part and got this much progress when he wasn't even trying. He could only imagine what a week or two would bear fruit to! He didn't notice any visible changes with Thunder, though his hooded sweater did look a bit worse for wear as it looked overly stretched along his broad shoulders by just a bit.

"Yeah, I love it. Let's continue this and then measure later. I have a good feeling about this." Thunder growled before going off to his next workout. Crash did the same, opting to continue his arm workout by going for barbells. Once he started to stack on the weight, he felt like adding more and more until he convinced himself to stop. He wanted to be bigger and if breaking his records on day one was part of it, nothing was going to stop him. Once he started curling off reps, the same sensation crawled through his body. His biceps slowly rose wider and larger as the seconds past, each breath from his chest revealing more and more bulk added onto his pectorals and torso and being slightly forced to keep his legs apart due to his quads gently grinding up against each other.

The rest of their workout was full of sporadic moments of size increase, which were more than welcome for the duo. At the end of their workout, the two finished close to noon and took advantage of the empty showers to admire any sort of new gains. At the very most, both Thunder and Crash had gained inches in overall size and a few extra pounds just after the one workout session. After documenting actual numbers and switching to their casual clothes, they noted that shirts were close to tearing already. When they made their way out of the gym, Crash couldn't help but make eye contact with one of the barbells that he had left. It was set to his prior weight, but something bothered him about it.

"Maybe just one more set before we go back." Crash said out loud, walking towards the barbell. He loaded up two more plates on both sides and kept them sealed in while Thunder watched with hands on his hips. Just what was getting into him? The eastern dragon admitted that the pump felt great, but maybe Crash was getting just a bit too into it. The lion-bull's tail swished as he demolished his first set in a matter of several minutes and snorted, searching around the gym in the pursuit for more plates. As he went through rep after rep, Crash's arms swelled and bulked with more muscle, his chest and shoulders following suit. His poor shirt now clung to his increasing frame, leaving him with something that mimicked a sports bra that was painted onto his chest. His doming, powerful furry stomach had made his shirt ride up to the point it met his chest in the small time he did finished his set with a snort. Crash's jeans were now close to bursting at the seams no thanks to his close to tree trunk quads and calves stretching the material. He'd done more than his own body weight clocking in at almost 300 without breaking a sweat, and he still wanted more?

Thunder's frown soon turned into a scowl, slight envy rising up in his chest. If he was going show him up, the least he could do was offer a rebuttal. The energy from the shake still racked him; he could probably do a few more workouts until the stuff wore off, right? Thunder bounded over to the bench press, stretching his arms and adding on a few extra large plates afterwards. As he loaded up, his arms surged and flexed with veins dancing along under his green fuzz, his pectorals daring to burst out of his t-shirt. When he finally got to lifting the weight above his head, it was close to being too light for him several reps later. With every push of the barbell upward, Thunder's back swelled, taking up more space on the bench with each tense and flex of his upper torso. His chest bloated thicker and wider, his pectorals soon tearing through the middle of his tank top and leaving the tatters along his growing shoulders and biceps. With a snort, he shrugged his widening bounder shoulders and flexed his arms, the tatters turning into confetti that fell to the floor underneath the pump addled dragon.

"Want more...bigger." Thunder grumbled to himself, searching around for something heavier. He tested the waters of his body, flexing his arms and chest and shrugging his shoulders and back. The eastern dragon sported enough width to carry more than several adults on his shoulders, each shrug and flex making his sides flare out. His eyes soon locked onto Crash, the hybrid deep in doing dead lifts with a weight bar that was close to bending from all the plates attached to it. The effect from it resulted in legs wider than Thunder could ever imagine. Any semblance of Crash having pants on was now laid across the floor, leaving him in the buff.

"If he wants to be like that, fine." Thunder grunted. He followed suit over to Crash with the nearest weight bar he could find and saddled it with enough weight to make the bar groan and bend as he loaded it up along his impossibly wide shoulders for squats. He took position next to Crash and settled into his own rhythm. The gym room began to fill the air with their grunts and growls of dominance, one of them attempting to beat the other in some sort of primal attitude bubbling on the surface of their newfound muscle and size. The constant squatting had forced Thunder free of his jeans and underwear, leaving the two growing behemoths free-balling as they continued rep after rep.

Being forced to carry close to thousands of pounds, their bodies responded with adding more and more muscle. The energy from the shakes made them desire more no matter what, even if they couldn't fit it on their limited bodies. With such a need and want for more size, the combination of body work along with how much they unknowingly digested, their bodies returned their desire in kind. With each and every rep, Thunder and Crash's legs grew thicker and wider, adding more and more size to the point they looked out of proportion to the rest of them. Veins lined along their gargantuan quads and calves before they started to split right along the middle. Keeping the weights gripped in their hands, their legs and lower body began to change. A taur-like lower body emerged for the both of them; the sudden emergence of their new pairs of legs caused another accident to happen.

"Shit!" Thunder's new legs and lower body buckled under their own weight in the middle of its emergence, causing him to knock over into Crash. The two dropped their weights with a loud clang, the two of them forming one big mess along the gym floor. The process of their legs forming now ceased, overtaken by an entirely new process that their bodies followed. The desire to get bigger by any means. Thunder and Crash's bodies combined and merged together with a hint of purple, almost like the goop they had downed in their shakes before, meshing their bodies together in a way that made sense. They were split right down the middle with an orange and green coat of fur; their upper torso dominated by sheer amounts of muscle--overwhelming traps, biceps fighting with triceps for space due to their impossible bulk even without two sets of arms dominating for space as well. Their two heads sat upon the beast of bulk, four massive pectorals followed suit to a powerful belly that complimented the overall size of his two chests. Where the humanoid torso ended, the taur body began. The lower body had been turned into a pantheon of muscle that burst from each leg, making the fur that covered it taut and thin to support such a monster. About eight of those massive legs kept the beast aloft. To complete the ensemble of massiveness, the beast came equipped with two shafts that pressed against each other, the length starting from the second set of legs to their torso. One black and one pink, the two beasts throbbed and shoved against one another, their combined girth constantly pushing against their fore and back set of legs. Their feet stomped about, the hybrid taur attempting to get a sense of him as he felt not one, but two sets of beach ball sized orbs drag against the ground.

A deep chuckle rose from the beast, the gym floor shaking in his presence. This...was a very good start. The hybrid, multi-armed taur beast lifted up the two barbells his original parts were lifting and found himself almost snorting at the weight. He could barely feel anything at all. He juggled them in his four hands before letting them drop onto the floor with a giant clang that shook the room.

"Bigger. Need more size." The beast's heads said together. Their taur body barely covered up most of the gym, but they sought to change that little detail. Body tensed, each bit of the orange and green covered monster pulsed. Veins thicker than the average person's wrist began to burst forth along their combined torso, dancing along their arms as they flexed. Each flex made those green and orange muscles swell with pound after pound of muscle stacked upon another. Nothing was too big in the taur's wake as his legs stomped around the floor, twin shafts throbbing along the ground as well. Their growls and grunts echoed through the room, their height slowly rising in tandem with their bulk. As if that weren't enough, their body demanded more of themselves to work with.

Soon as they reached the ceiling of the gym, the taur beast burst through, tearing through the top with all four humongous arms, ripping it apart like paper and rising out of the debris. Close to a story tall, the taur's arms rose up and flexed again, muscle bursting forth in waves across his body. His legs covered more ground now, allowing him to destroy the remnants of the gym with ease as he became larger and larger. Buildings that stood torso height to him were shoved out of the way with a beefy arm to make more room until he burst forth with more of himself.

Four arms soon gave way to six, the taur's humanoid half stretching higher and larger to accommodate every bit of muscle that was applied soon after. The third set of arms and pectorals, each green and orange flexed and tensed, newfound veins pulsing all over until the beast's two heads grinned in delight. As if that weren't enough, he still wanted more. A third head soon emerged, purple goop giving it life from somewhere on the beast's frame. The head took on features of the two original halves; bull horns, draconian face orange in color with wooden eyebrows and snout along with two red whiskers dangling from each side of their muzzle. Soon after it appeared, the beast felt a powerful throb beneath their legs. The twin shafts that had started drooling precum from their emergence soon began to split down the middle. He panted and grunted as now a third shaft formed, this one completely black in color and shoved itself right between the first two and just as hefty and productive as the others. Six pairs of nuts now formed, dragging behind him and leaving massive trail mark in the ground as the humongous sac now had enough space to topple a few buildings itself.

The taur-beast couldn't help but revel in its own size, stepping into the city as it grew larger and larger. He began to span stories tall, all six arms fighting for space as it chucked buildings down, the debris stomped or smothered to oblivion by his broad, oversized paws or the dragging sac behind him. He needed a place where he could just spread upward and outward as much as he wanted.

"Center. Good." He rumbled strongly. He simply trailed off for what he thought was the center of the city, placing himself right between after he ripped up a few buildings. He could hear the screams of the city folk that ran away from his frame, but some were either caught in the debris or flowed away from the increasing streams of pre that he left behind. With a snort, he laid on his side, spreading his side legs up to get a look at himself. Aside from his eight powerful legs, those three cocks were still spewing pre madly, every throb and pulse making him shudder in delight after getting a full look at the mess. He'd careened past hundreds of feet tall, his body growing impossibly wider and taller with every passing second. Those three shafts were very close to reaching his head as the next increase found them slapping along his overly packed torso.

"More..." he rumbled out before he took to one more thing. He really needed to deal with these three poles. Every bit of grinding and pressing against each other in a messy function had him over the moon, it was a miracle he hadn't blown off. Using all six arms, he pushed all three enormous poles upward into each mouth, forcing himself to suck, slurp and drink every bit of precum he could muster. People standing by would hear the beast's sac gurgle and swell with more production as he messily gave into himself and got even bigger because of it. Over two hundred feet tall and several hundred feet long, he still wanted more. Those overbearing six pack nuts would be able to smother a city block or two with their circumference alone.

Every gulp could be heard as he covered more and more distance. It got to a point that he didn't need his hands to support his own shafts while laying on his side, allowing all six to grope and squeeze the powerful, sensitive flesh and the veins that were strewn across it. Each vein could probably range cars in size as they pulsed, each of those shafts well over twice the size of an 18 wheeler, possibly even their own buildings. Each digit roamed around before finally reaching the urethra and simply drummed their fingers along it as they sucked right from the tap, groaning heavily. Each head had to come up and let out a pleasurable growl as no drop was left spared from the already large puddle that had accumulated on their arrival.

With one powerful throb, the mess continued. Spanning close to three hundred feet, those shafts suffered an overload of pleasure from the sudden growth and erupted, each one right after the other in succession. Waves of white spewed forth from the three shafted beast, flooding the vicinity in white and filling up the taur beast with what he could drink of the sticky, musky loads. He bucked his hips into the air, positively wracked with the sensation and spawning yet another cock, leaving him at four spewing shafts and a sac loaded with eight orbs that continued providing the beast more and more to fill himself with.

The monster taur continued flooding the next few blocks as the minutes passed, each sensory overload of one shaft going off leaving him still until he shuddered and another shaft was born. Now close six shafts were firing off the three headed Cerberus taur, each separate orgasm as powerful as the one going on next to it. His roar penetrated the skies as did his desire for more rang through on his body. Two extra shafts later and the beast was unable to get up as he kept on blowing with eight cocks in tow and an obscenely packed sac with about a dozen orbs in there. Most of the city had been pinned under his close one mile frame, muscle bulging at every single bit of him. His three heads were pinned under the swell of their mountainous traps, each set of pectorals jutting out feet before them along with an overly cum filled belly from their previous drink. Soon, they'd keep spreading and eventually smother the entire area at the rate they were going; there was no way of hiding this even if they could. The waves of cum that followed forth spilled into other neighborhoods, leaving the streets in white and a powerful, musky smell that permeated into the buildings that were still standing.

Damn near on the other side of the city, the same smell caused Jake to rise from his sleep. After getting a bit of coffee and opening the window, he was gob smacked with the toxic scent and immediately closed it and turned on his ceiling fan.

"What the hell!?" He exclaimed. He observed outside the window with his coffee cup held near his nose to combat the smell and noticed that the streets were covered in white. An almost familiar shade if he looked close at it. He turned the television on, and his curiosity was filled in an instant. The news channels were on blast, talking about some sort of enormous beast that appeared in the center of the city and started strutting itself and flooding the place. They called for immediate evacuation and advised to wear something to cover your nose. The closest picture provided by a citizen caused Jake's jaw to drop.

"No...no, no no no no." They couldn't have. Jake opened his fridge to check the vat and noticed that a lot of it had been missing. Did they actually take more than intended? And did it result in...whatever that was? No, that couldn't be it. "I bet they're just in the gym or evacuated like everyone else. No way that the giant green and orange monster that had whiskers and bull horns is them." Jake tried to convince himself otherwise but continued to fail.

Staring at the television again, he sighed and packed his things. Hopefully this stuff would wear off. Whether it did or not, he was certain that it wasn't his fault this time and he'd rub this in Crash and Thunder's face if or when it wore off. He projected that one dosage of the stuff would last a day, so maybe it'd go on for a few days more? Either way, Jake didn't want to stick around to see the end result if the monster didn't move on somewhere. That was, if it could move. The polar bear was never one to be jealous of size, but the poles that thing was toting had him flushed by the time he left his apartment.

"Stupid Crash and his size antics..."
