Just look at this unstoppable growing beast 😍

From the first two pictures to the second two in just FIVE MONTHS. Holy hell.

Growing so big that quickly must feel incredible 😩

You like being down there, don't you?

You better run!

This is the last camping you'll ever do, and the last thing you'll ever see

The endless storm.

Your journey all the way in.

That is America's ABS!

In you go, head first, nice and slow

You won't run away from him...

The jungle's beast

Enjoy the party! - with Tom and Shawn

How's the view from down there, boy?

There is something about a muscle daddy, dripping with sweat that makes me suddenly very thirsty...

"Good Luck."

Alexey was exactly as the catalog had promised--unbelievably huge and muscular, stuffed into a tight blue shirt, an adorable baby-face crowning the body of a titan. Jim’s heart leapt at the sight of him--Alexey smiled as he approached and offered a beefy hand, but the guy’s unbelievable size was intimidating as hell. Jim, a slight redhead at just over five feet, tried to keep his hands steady as Alexey patted his shoulder--he felt like a child next to this giant!

“We will have fun, I promise,” Alexey carefully pronounced with a thick accent. “What would you like to do first? Walk along ze beach?”

Jim could barely contain his excitement. “Let’s go back to my hotel room!”

Alexey sighed, his huge bulk swelling as he inhaled, then deflating quickly. He looked around anxiously. “I could take my shirt off, we could dance at a bar…”

 “No!” Jim protested. “Hotel room!” Alexey’s size was terrifying but Jim had paid good money for this opportunity.

 Back at the hotel room, Jim poured a glass of champagne while Alexey arranged his things. “So, how did you get like this?”

 “Lots of training and discipline,” Alexey said, puffing up and surveying his wide body from edge to edge.

 “No, I mean…” Jim walked behind Alexey and yanked up the blue shirt to reveal a small metal panel--a small keypad, a dial, and a little screen flashing inscrutable data. “Like this.”

 Alexey signed again. “I… did not understand the contract I was signing.”

 “Well, I’ve read the manual, let’s get this going!” Jim said. “Flex for me!” Jim had a seat and sipped from his glass.

Alexey hit a double biceps pose, then spread his lats. His massive chest stood out like a big meat shelf.

 Jim wasn’t satisfied. “No,” he protested. “Take your shirt off!”

 Alexey was reluctant but did what he was told. He hoisted up his shirt with one hand, needing help from Jim to pull it up over the bulk of his torso (which thrilled Jim to no end). Jim had a seat, breathing deeply from the warm and lightly sweaty garment while Alexey hit some mandatory pose.

“Turn around!” Jim screeched. “Show me your back!”

 Alexey seemed to know where this was going, but obliged anyway. He hit a back double bi, spread his lats wide--but then Jim leapt to his feet and tapped on the keypad above Alexey’s waist. “555 freezes the body, but leaves your head intact, right?”

 Alexey, frozen in place from the neck down, nodded. “Yes.”

 “This is amazing!” Jim said, stripping Alexey naked and taking the time to explore Alexey’s body, his fingers digging into every muscle, probing every inch of the massive Eastern European. “You’re so big... You can get as big as you want now that you had this installed right?” Jim tapped the edge of the keypad with his fingernail--tink tink tink, against the metal.

 “Well… I was very big before it was installed…”

 “But if I remember correctly… 1472, then the star key…” Jim hit the buttons as he said them aloud.

 “Hey, wait, don’t just…” Alexey’s protests fell on deaf ears as the process began: slowly, with the sound of an inflating balloon, Alexey began to rise up, his body remaining proportionate but growing in all directions. No longer afraid of this man who was completely in his power, Jim dropped his pants and starting jerking his dick as he rubbed his hand over the expanding man. Alexey’s face seemed to panic as he rose up and away, seven feet tall, then eight, larger than any human who would ever live, approaching the ceiling with no way of stopping himself.

 “You’re gonna burst through the ceiling!” Jim gasped breathlessly, now straddling Alexey’s inhumanly gigantic leg like it was an unsaddled horse.

 “Yes, I am--please, the reset button…”

 Jim groaned, his whole body went rigid, and he came--just as Alexey’s head touched the ceiling and pressed into it.

 “Okay, okay,” Jim said breathlessly. Let’s take care of this…” He hit the flashing red RESET button and Alexey’s body snapped back to its starting (but still massively muscled) size.

 “Thank you, now please--” Alexey began, still facing away from Jim but struggling to see what was going on behind him.

 “I believe 6-1-1-pound sign causes expansion with no height increase, right?” Jim punched the corresponding code and Alexey’s back immediately started to swell, his arms inflating like tires, his legs spreading apart--mass pouring onto his frame without an inch of height added.

 “Holy shit…” Jim said, sinking to his knees and inspecting the gargantuan ass that was still inflating before him. He dug his face in, tasted its musky depths, licked from top to bottom as Alexey moaned and struggled.

 “Unh… please, be careful… ohhh…” Alexey moaned. Jim could barely hear him from the warmth of Alexey’s ass. Jim emerged and pressed the reset button again. “I guess it wouldn’t be any fun if you got so big your bones started breaking.”

“Yes, please, now… the code to let me move again is--”

 “Y’know, I could shrink you down to the size of my dick, you know. I’d love to see a big guy like you wrestling with my cock like it’s a contender.”

 Alexey’s eyes fell. “Yes, you could.”

 “I’ve studied the whole damned manual, Alexey. I wanted to get my money’s worth. See, I’ve got this interesting little kink… I mean, it’s one thing to fuck you… God, it’s a damned dream come true… but you wanna know what my fantasy is?”

 Alexey’s brow furrowed. He seemed afraid to ask.

“Code 9-9-1-4-9-star,” Jim said confidently. He’d been waiting for this moment. Alexey’s eyes went wide--he had no idea what this setting would do--and his mouth suddenly formed an O-shape. Movement returned to his limbs for just a moment--but then he froze again. His whole body took on a plastic sheen. Suddenly the features of his body lost their details. His face was painted on. He maintained much of his size, but now he had the puffy shape of an inflatable doll.

 Jim fingered the doll’s open mouth hole, played with the same opening between the seams of its blocky rubber ass. “I’ve dreamed of fucking a living blow-up doll for my whole life, Alexey,” he whispered into its drawn-on ear. “Let’s see how many time I have to fuck you before I get it out of my system completely.”

“I do hate to interrupt any Asgardian Halloween celebrations but I decided this year I would come as your gigantically muscular savior!” The mischievous god boomed through the kingdom.
