“[color=#b9ffff]So, what exactly am I getting myself into?[/color]” the short feline asked, looking over towards his lapin friend, the other boy shrugging. “[color=#89668e]Oh nothing special, just a large bit of swelling[/color]” he said candidly, like it was nothing. “[color=#b9ffff]Define ‘large bit’ because I’ve seen you get pretty huge before[/color]” he pressed, wanting more information. The bunny boy huffed “[color=#89668e]It’s nothing crazy, alright? You’ll be able to fit back through the doorway, and the suit I lent you can stretch, so just enjoy the run~[/color]” he said, nudging the other. The feline huffed in return and nodded, “[color=#b9ffff]Alright… I’m just kinda embarrassed, y’know? It’s my first time after all[/color]” The rabbit chuckled and handed the other a water bottle, “[color=#89668e]Yeah, I know. But you’ve seen me do it all the time right? It’s really not a big deal[/color]” he said, taking a water bottle of his own and bringing it up his slightly pouty lips, pouring a cool bit of refreshing and pink liquid down into his throat. The Siamese tensed up slightly, but looked down at the bottle in his own hand and did the same.

The rabbit when by Nao, the feline KC. Nao was a bit of a scientific marvel, a being made of part machine and part flesh, with modifications added to his hair and arms. More than anything these were cosmetic, just things that made him feel more comfortable about himself. KC was all natural, although he certainly had a plumper-then-average backside. Five solid feet of feline flesh, with an inordinately high amount of fat packed around and below the hips. The lapin had gotten his modifications several years ago, and ever since he had been experimenting with a new experimental ‘product’ on the market: Gro. Gro is a concoction that allowed people to temporarily enlarge a body for some time, and had varying effects on people based on their own genetics. For Nao, it was quite effective, and his modifications had made it even more so. An average dosage had him swelling all over, to the point where he would shred out of clothing of become too wide to fit through a doorway. The sensation of size was nothing short of fantastic. The drug itself wasn’t an aphrodisiac, but for Nao it might as well have been, the excitement at seeing himself enlarging being enough to push him over the edge. Now, it was KC’s turn. 

KC had never taken Gro before, so he wasn’t really sure how it wasn’t going to affect him. But he certainly had a wide, round posterior, which some people mistook for being caused by Gro, since some people on the drug actually wound up less plump then him. This was actually how he met Nao, who had stopped him to ask what variation of the medication he might have taken. He was slightly nervous about the effects, not wanting his rump to bloat too much, but it was something he was finally ready to try, after watching Nao enjoy it so much. His intro dose was small, or at least he had been lead to believe that.

The unassuming water bottle graced the feline’s lips and let the cool, cherry flavored fluid slide down his gullet. He let out a slightly surprised hum, the liquid tasting better than he had expected it to. Memories of cough syrup from when he was kitten came flooding back. The feline sighed happily and closed the top, having drank a surprising amount of it all in one go, “[color=#b9ffff]Alright, so shall we get go-oooiiinnnggg….[/color]” KC trailed off, quirking a brow over at his friend, who was staring at him like a statue. “[color=#89668e]Did you… drink that all… just now?[/color]” Nao said softly, the feline freezing in response “[color=#b9ffff]Sh-should I not have? Oh god… I knew something would go wrong![/color]” he said, panic quickly surging through him. The purple lapin giggled, “[color=#89668e]Nah, you’re fine! Come on, let’s get going[/color]” he said, starting to jog a bit and patting KC on the rump as he passed him, oversized  high tops thudding as they stepped onto the concrete. The feline huffed, but started to move his body to catch up, “[color=#b9ffff]Not funny! Mess with me again and I’ll spike your next dose so it’s double![/color]” he said, now running at the other’s side. “[color=#89668e]Hah, you act like I wouldn’t like that![/color]” Nao teased, elbowing the other’s side as they made their way down the street from Nao’s apartment to the trail along the road. 

The jog was KC’s idea, surprisingly enough. The two both had an affinity for running, but rarely did it together, as it wasn’t the best social activity. This time they had added a bit of excitement into the mix, a water bottle on each hip as they ran down the road, their suits clinging to their figures. The material was certainly exposing, but it was supposed to be, the latex-like material having pushed out all the air, and conforming to the shapes of their bodies, while also giving them room for movement. KC’s was red, Nao’s purple, each one lacking sleeves and showing off their shoulders. The colors matched their flavors, KC had a cherry concoction and Nao’s potion was purple. 

The feline was embarrassed enough as it was, extremely conscious of his rear as it jostled behind him, cheeks bouncing and clapping against one another as they bounced off his thighs, which rubbed together. Naturally, he wasn’t the fastest jogger. Nao had to go a bit slower than usual, but this allowed him to enjoy the sights. The Siamese huffed as he trudged along, feeling a bit of a tingling under the suit, but nothing extreme. “[color=#b9ffff]How long… does it take… to start?[/color]” the feline asked between breaths, “[color=#89668e]Well if you’re impatient you can always drink some more~[/color]” the lapin teased, KC shutting his mouth in response.

They made it to the trail, which didn’t have all that many people on it, but was certainly within view. It made a loop around the city, cutting through parks, shopping districts, and running along the beltway so it could be used as a commuter bike-path. It was an early Saturday morning, the sun still making its way into the sky, so people were sure to be out and about soon enough. Two started to make their way down the paved path, occupying both lanes with wide hips as they jogged along, practically begging for attention. The Gro hadn’t kicked in yet and some people were noticing, maybe it was the brightly colored jumpsuits, but they got their share of whistles and cat calls as they went. Nao giggled, blew a few kisses, and even called back, while KC stayed silent. His cheeks crimson to match his outfit, just jogging the route like he normally did. Of course on an average day the boy got a bit of unwanted attention, but today the two stood out like sore thumbs, so it was certainly coming in. KC had forgotten all about the Gro, he was just focused on his jog at this point.

Then it started. The young man let out a cherry-scented belch, his stomach rumbling slightly, “[color=#b9ffff]Guh… is that supposed to happen?[/color]” The Nao giggled and nodded, “[color=#89668e]Yeah, the first time is always like that. I remember mine, was burping for hours! But don’t worry, that won’t happen to you.[/color] he teased, the feline groaning in response. He trudged along, but he certainly felt heavier than usual, his pace slowing down as he struggled to maintain momentum. Nao gave the other a pat on the rear “[color=#89668e]Don’t worry, this is the worst part. Once you get through this it’s smooth sailing~[/color]” he said, the young man maintaining his pace effortlessly, even as his growth began to kick in.

More often than not Nao’s swelling took place in one area: his package. His thighs and rear would swell out a bit, but his groin would be monstrous, nuts the size of yoga balls and a dick the size of a canon. So the front of his suit started bulging, a clear trouser snake forming along his thigh, orbs bloating out and bouncing along. KC tried not to stare, but it was hard. The sight of his best friend’s package swelling right before his eyes was unlike anything else. Nao giggled, “[color=#89668e]Hey KC, I think yours is starting too~[/color]” the lapin teased, the feline quickly looking down at himself. He was right. The siamese’s rump was noticeably plusher and rounder then it had been before, his thighs swollen as well. But that wasn’t what he was staring at. KC looked directly down at his chest, where two breasts had started to form. The feline was speechless, cheeks bright red as he mindlessly jogged along, staring down at his own chest as it steadily pushed out the tight material of his suit. Nao grabbed him on the shoulder and tugged on him, forcing him to turn as the trail did and preventing him from running straight into a tree. “[color=#89668e]You can have fun with your new tits later, but we have a trail to run! We’re only a third of the way there[/color]” the lapin said, winking at the other male, who remained speechless, eyes reverting onto his companion. Nao’s groin was starting to reach those absurd proportions, each nut of his larger than a softball, cock a foot in length and continuing to grow, now as thick as a soda can. His thighs and rear were continuing to fill out, but in addition to that the boy’s lips were noticeably plumper as well. KC instinctively touched his own, but they hadn’t changed.

The stares were becoming more frequent, distant camera shutters could be faintly heard as the duo made their way along, heads turning to follow them. Nao’s rear soon looked like KC’s normally did, and KC’s was quite large now. The boy’s hips flaring out, each of his ass cheeks looking to be the size of a watermelon, jutting off of him and sticking out fairly wide to his sides. His thighs resembled squishy, jiggly tree trunks, and his sac had swollen up slightly to make it much more pronounced. The feline’s rod was swelling slightly, but was dwarfed by his own thighs and Nao’s monstrous dick. The lapin looked as if he had three thighs, his massive dick sticking down his leg with a clear outline visible, including some of its veins. His nuts were the size of basketballs, each one churning with a full load of seed. There was no leaking however, and despite the extreme added weight, Nao continued to run as if it was nothing. KC on the other hand continued to struggle, the newfound weight on his chest nearly causing him to topple over multiple times.  Each breast was about the side of his head now, the heavy orbs of fat hanging off of his chest and bouncing along with his movement. He panted, sweat dripping down his brow as he pushed himself to keep up, Nao whistling at him. “[color=#89668e]You’re doing great KC! We’re over half-way there.[/color]” the lapin said, reaching for the bottle on his hip and taking a chug of it, then continuing onwards. The Siamese felt compelled to do the same, his throat nice and dry at this point.  “[color=#b9ffff]Yeah… just… struggling to adjust....[/color]” the feline huffed out, breasts and ass jiggling with every little movement. Nao giggled, “[color=#89668e]Yeah that’s kinda my fault, I gave you a little more than you asked for, but I wanted to push your limits![/color]” he said with a wink and a pat to the feline’s rear, KC burning red in the cheeks. “[color=#b9ffff]Oh you are gonna get it now, when we get back to your place I will CRUSH you![/color]” he said, a grin on his face. Nao grinned back, “[color=#89668e]With that ass? I hope you do~[/color]” he teased, giving the other a smack that was much firmer.

More whistles and stares came from the sidelines, people now watching the two boys bounce and balloon along the road, a biker stalking them with a camera strapped to his handlebars, filming the whole endeavor. KC continued to physically struggle, but at least he wasn’t so nervous any more. The second gulp has stirred the swelling in each of them, Nao’s rod stretching all the way down his leg now, the tip thicker than his calf. His rear had stopped at generously plump, but his lips had certainly kept going, the lower one looking as thick as a sausage! And his nuts, each one was bigger than the boy’s head, pressed firmly against his thighs and looking quite absurd. As for KC, the amount of fat that had managed to fit onto his body was nothing short of incredible. His hips were wide enough now to stretch beyond the lane of trail her had taken, thighs now reaching that car-tire thickness. The feline’s plush cheeks looked larger then pillows, surely big enough for a person to comfortably rest their head on. And his chest, with boobs that drooped down towards his navel due to their sheer size, his arms unable to wrap around them as they had forced cleavage in his suit, the valley looking like you could stuff a textbook into it and struggle to get it back. Above all he felt heavy, and with all the extra fat on him he surely was! 

They had lost some of the crowds by this point, as people went out to get some Gro of their own to enjoy the day, and the sun had settled into the sky now, noon soon approaching. They turned off the trail, and ran down Nao’s street just as the sound of ripping threads began to fill the air. Suddenly each boy would notice a tear, one along the lapin’s shaft and the other right across the feline’s cheeks. They looked at each other, a bit shocked, “[color=#89668e]RUN![/color]” Nao called out, sprinting on ahead with KC not too far behind. As the two hustled the contents of their water bottles jostled on their hips, the sound continuing as those tears became louder. KC’s suit ripped along his cleavage now, more of his tit flesh poking out, one of Nao’s nuts soon seeing the light of day. The lapin fumbled with his keys a bit, working to unlock the door as KC approached from behind, panting. “[color=#b9ffff]I have no idea… how you can keep doing this…[/color]” he said, the lapin grinning at the feline as he undid the door, “[color=#89668e]It’s easy, you just gotta keep pushing yourself[/color]” he said. The door swung open, and Nao slipped inside, KC following behind, until his hips got wedged in the entrance. KC’s eyes widened “[color=#b9ffff]H-hey, you said this wouldn’t happen![/color]” he said, panicking. Nao leaned in, and pressed his swollen lips up against the other boy’s and silencing him with a kiss.
 
It lasted long enough for KC to ease into it, tongue slipping forwards a bit as he tried to press against the other’s over-sized kissers. Nao pulled back soon enough, and grabbed onto the feline’s wrists, pulling on him fiercely. “[color=#89668e]We can kiss more once you’re inside, now come on and push! We’re gonna need both of us if we want to fit that ass in here[/color]” Nao said, completely composed. KC was red in the cheeks once again, a small growth spurt having been caused by the thudding of his heart in his chest. Soon enough the front of the suit ripped to the point where his tits flopped out into the open, the sudden weight on his front enough to let him slip through the door with a ‘FWOOMP!’ The Siamese toppled forwards, the other falling onto his back with the feline on top of him, those tits pressing directly into his face. KC quickly blushed and climbed off of the other, “[color=#b9ffff]O-oh god I’m sorry, are you alright?[/color]” he asked, rising up onto his feet, not even thinking to conceal his new breasts, large, puffy nipples sticking out on the end of each globe. Nao stared for a moment and sat up, rubbing the back of his head, “[color=#89668e]Oh I don’t know… I might need some big, soft pillows to rest my head on for a while.[/color]” KC nodded, “[color=#b9ffff]Sure thing, let’s just get you upstairs and-[/color]” the earnest faded from his face and he rolled his eyes, “[color=#b9ffff]Oh haha, I get it. Come on and get up, I wanna go sit down for a while[/color]” KC said, reaching a hand down for Nao. The other boy took it, grinning, and pulled himself up off of the ground, “[color=#89668e]Sounds good to me~[/color]” he said, dusting himself off and heading up the stairs.
