Kinktober 2024 - Muscle Growth

Rund the fox sighs as he looks onward at the beach's gym. So many musclebound men are using the various equipment the area has to offer. Many of these men have very toned upper bodies. Biceps that are as big as Rund's head. Many of them are lifting a hundred... even two hundred pounds almost effortlessly.

In comparison, Rund is as average as average can be. Maybe even a bit lanky.

"Man, if only I could be as strong as that..."

A shadow looms over Rund. He turns to see the white sharkfox, Darko, smiling at him. His eyes glisten with ideas through his ebony locks. His smile slowly opens to a devious grin with sharp teeth. His tail slowly wags behind him with a black tip that looks like it's oozing ink. Rund thinks that might have been his imagination though. The most striking part about him though is a pair of rainbow speedos that stand out against his white and black frame.

"Can I help you?"

"Make a wish!"

Darko flicks a tiny pinch of gritty purple dust right in Rund's face.

"What's your deal," Rund coughs. Before he could tell him off, he suddenly felt a compulsive urge to shout, "I want to be the strongest here!"

Rund looks around haphazardly, hoping no one heard him shout. His attention is drawn away when he feels something swelling within him however.

The fox feels his left arm tensing up. He looks over just in time to see his bicep **swelling** upward!

"Holy...!"

Before he could finish that, Rund felt and saw his other bicep doing the same thing. The fox nearly falls over as his chest broadens. A fresh six-pair chisels itself right on his abdomen. His chest puffs out into a pair of pecs. He tries to stand up but finds he is way off balance due to his legs still being the same.

Rund gasps as he feels Darko rubbing one of the biceps.

"Who are y--"

"Shhhh," he interrupts. "Just enjoy, beefcake~"

A fortifying leg takes a huge step forward as Rund's other leg bulges out with chiseled muscles. Sand splashes up with every stomp he makes. He takes a good look at himself...

"Holy fuck, I'm... jacked," he exclaims. He's in disbelief that the muscles in his body are *real.*

Rund is as big as the strongest guy in the gym area. He pumps both biceps, seeing them go as high as his eye level. His pecs creak as he continues to through poses. The fox's showboating starts attracting the attention of the other beachgoers. Most of them didn't even notice the unassuming guy he was before, so they stared in awe at how the heck they missed this beefcake of a fox (especially with that huge blue bulge in his speedo)!

Darko hangs off one of Rund's biceps with both arms. He's the only one knowing what's coming next.

Suddenly, Rund feels every muscle in his body burning with energy. Now with the figure of a bodybuilder, the power of the dust is no longer targeting specific body parts. The vulpine's entire figure ***BULGES*** as every muscle becomes rounder and thicker. Hands and paws surge in size as his palms become big enough to cover an entire head. Veins protrude all over while his biceps grow to be as tall as a car!

The hulking mass of fox muscle feels like he should be worried, yet he can't bring himself to do so. In fact, Rund feels like this is how he should be.

"B-bigger... stronger... more...! **MORE**," he bellows.

Everyone takes notice. Even the ones at the gym are looking rather afraid. Their hearts shoot to their throats when they see this beefcake to end all beefcakes actually lumber towards the gym!

**THUMP. THUMP. THUMP.**

They scatter like roaches. Anyone who's leaving three-inch-deep pawprints in the sand is not something they want to be close by.

Darko thinks otherwise as he follows close by, sneaking in the occasional stroke with his tail.

"Already wanting more," Darko teases. "Well, who can blame ya? Never enough for meatheads like you~"

Rund steps in the middle of the area before grasping a barbell... in each hand. He effortlessly pumps 300 pounds for each arm, enjoying how they make his muscles burn from the resistance. As impressive as it looks to the onlookers, it's just a warmup for Rund.

With all eyes on him, he got the attention he wanted for being so big and mighty (even if not all of them are the reactions he was expecting).

"Yeah," Darko nods. "I'm not letting you go. You're coming with me when you're done here, gym rat~"

The mischievous fox gently strokes Rund's abdomen while his tail wraps around his midsection. Every part of him feels perfectly chiseled. There's not a single part of him that doesn't feel like it has the power of a truck behind it. The big burly vulpine gives a grunt in response.

Darko gets another pinch of dust ready for his new boyfriend.
