Leo was busy reading when he noticed that Jake had left his laptop on. He put his book down and hefted his large frame over to the table to shut it down. He stopped suddenly when he saw what was on the screen.
It looked as though Jake was playing around with some sort of highly detailed character creator before he went to bed and he had re-created Leo in surprising detail! The beagle looked over the naked model, and then back over to his muscular arm, realizing that even his fur pattern matched exactly.
"Wow what sort of program is this?" he chuckled to himself, his curiosity now peaked as he sat down in front of the Shiba's computer.
His eyes wandered over the options and noticed the muscle slider sitting at 65%. He pondered what the model would look like with it cranked to 100 and made the adjustment. The digital version of Leo suddenly ballooned out with muscles. Its furred skin was stretched to maximum and all the muscle groups seemed to be fighting for space on its frame.
He laughed at his digital doppelganger and went looking at the other options to adjust.
A few moments went by until he leaned back, arms crossing his pecs and let out a small woof.
On the screen there was a version of Leo that looked like it had been overdoing testosterone all his life. Not only did the digital beagle have a muscular build that would make everyday tasks a struggle, he also gave it a set of genitals to match its size. Its scrotum was taut, filled with melon sized testicles. Its sheath now ended squarely in the middle of the 8 pack abs, the red pointed tip jutting out as it was too big to fit inside anymore.
"That was enough messing around. Back to homework."
He was just about to close the laptop when a window popped up asking if he wanted to save the changes. He clicked yes on a whim, as he may ask Jake to screw around with the program some more. and flipped the screen down.
Leo walked back over to his chair and picked up where he left off in his assigned reading, blissfully unaware to what he was going to become thanks to the settings Jake had selected earlier.
Muscles all over his body slowly began to inflate. He started to fidget a bit as he tried to get in a comfortable position. He moved his legs wider, the white and brown fur growing tighter as his quads began to fight for space in his shorts. His scrotum suddenly ballooned out, reality shifted making the now taxed shorts custom tailored to Leo's new size. He scooted further forward in the chair to give his lower appendages the room they needed. Even his tail began to thicken, no part of his body going untouched.
His abs soon rose like bread rolls baking in an oven, only to be intruded by a white-furred tube, thick as a two-liter bottle. The red head of his penis now spearing out of the opening, never to be snuggled by his sheath. Above his pectorals began pushing forward from his core jutting out like two massive mountains. His arms two began growing in size as though two watermelons were shoved under his fur, his forearms bulging as veins began creeping along his body, feeding his new bulk.
Leo grunted with a much lower voice as he had to adjust his book. He had to now hold it with one hand, keeping it out and up so he could see it without his shelf-like pectorals in the way. He rocked his stiff neck, deltoids bulging with strength.
For whatever reason he just couldn't focus on his homework at this moment.
