Thank you very much!
"So, I just take this pill, and I'll get strong enough to take on Andross, even without an Arwing? I know Slippy can do some really impressive stuff, Fox, but... I don't know." Falco held the tiny capsule in his feathered fingers, examining it closely. Fox nodded. "Trust me, Falco. With this, you'll be our greatest asset. You'll be a hero! What's the worst it could do?"
The two had flown to an abandoned outpost planet, with only them and Fox's Arwing on an abandoned base's surface.
Falco shrugged, and with a bit of a theatrical grin, tossed the capsule into his beak, and swallowed. Fox gained a sly grin. "It'll take just a minute to activate. And, well... Let's just say, Falco, if I loved your figure before, I'm going to adore it once it's finished." Falco blushed a little bit, smiling at Fox. "Heh... Explains THAT." Falco pointed to Fox's crotch, and Fox smiled a bit wider, not bothering to hide the growing bulge in his pants. "Sorry. Just excited to see what's going to happen. Oh...!"
Fox's eyes lit up as he watched Falco closely. His suspicions were confirmed as Falco's muscles seemed to expand, his biceps pushing into his sleeves, his pecs bulging beneath his shirt, and his abs forming a distinct shape on his shirt's stomach. Falco gained a mild look of discomfort as his clothes pushed into his growing form, his eyes growing slightly wide as he realized what was happening.
"M-my muscles..." He stammered, feeling himself expand, failing to stop a moan from escaping him as he felt his cock growing hard beneath his pants. Not just hard, but bigger. He could feel his balls expanding, as well. Before he couldn't take the pressure on his body anymore, his clothes began to shred apart, falling to the ground in shreds. His boots fell apart, revealing his golden lower legs and feet. Falco looked down and saw his feet splayed out, and seeming to continue growing. Falco then noticed that, not only were his muscles expanding, but he seemed a whole meter taller than Fox, when the two were only a few inches apart a minute ago.
"I'm growing? Fox, is this...?" He looked at Fox, and fell silent at the sight of Fox unbuckling his belt and pulling down his underwear slightly, showing his erect cock and beginning to stroke it. "It is, Falco. And- mmf... -You're not just going to be our greatest weapon, but you'll also be the biggest!" Falco watched in awe as his body grew, and grew, and grew, already three times the height of his furry friend and far more muscular. Soon enough, all of his clothes had fallen to the ground in useless shreds, save his underwear, which was holding on by a thread. It bulged as his cock grew, and it grew bigger in addition to growing erect. His underwear soon fell apart, revealing Falco's swollen, throbbing erection, and giant blue balls. Falco couldn't help but gawk at his length and hold it, moaning as he felt it throb in his grasp. "Oh, wow... This is incredible..." Falco mused as he grew to an astonishing forty feet tall, before he felt an odd sensation on his ankle. Turning his head, he spotted Fox, climbing up his growing leg.
"Sorry, Falco. I just can't resist you." Fox smiled as he climbed up towards Falco's groin, latching onto his balls and climbing onto his cock, grinding against it and moaning all the while. Fox felt Falco's cock growing against his body, throbbing and pulsing as precum began to drip from Falco's member. Falco couldn't help but moan, his newfound height starting to leave imprints in the concrete ground.
The growth continued for a while, with Falco growing and growing, bigger and bigger. His growth didn't cease once he was as big as a skyscraper, which gave Falco, who was now desperate to ease his erection, an idea. He picked Fox up and put him on his shoulder, stomped his way over to a building, long abandoned, and wrapped his arms around it. He then moved his hips back, his cock aimed directly at the massive building, and then rammed his cock into it. Millions of shards of glass fell to the ground, with Falco unscathed. The sensations of this new experience was unbelievably pleasurable to the mammoth bird, who began to fuck the skyscraper more and more vigorously, his moans echoing throughout the mountains of the abandoned planet.
Soon enough, Falco's cock was satisfied, and geyser upon geyser of cum flew from his cock, flooding the streets of the city and destroying the building his member was fucking. Falco, however, soon felt another urge overtake him. He turned his gigantic head to Fox, still on his shoulder, and smiled.
"Fox... How big am I?" Fox smiled, shrugging. "Slippy said you'd be pretty big. If I had to guess... a good thousand feet, at least. Falco, however, looked unsatisfied. "That's not enough, Fox. I want to be bigger." Fox smiled wider. "How big, exactly?"
Falco grinned deviously. "I want to fuck the planet."
