Jake couldn't help himself thinking up some more changes. He thought now that he was mostly animal he would move to something a bit different. But what exactly did he want? Jake slumped back into his chair trying to think of something. He thought he'd give another look in the mirror to see if he'd get inspiration. Jake looked at himself... a male human shiba, with golden blond hair, wearing nothing but boxers. Looking at his current changes was still satisfying at least. He started to flex and stretch out his arms, letting out a yawn. After a few tired blinks, Jake's eyes popped open. He looked at his physique, and started flexing his muscles. "There we go!" He said rolling his chair back to his desk.
Jake decided he wanted more muscle, as he'd been pretty thin for most of his life. He wondered what it would feel like to actually have toned bulging muscles. So he decided to upgrade his physique accustomed to a body builder's. Once Jake typed in muscle, a slider showed up with a skinny model on the left to a hulked out model on the right. Jake had figured there would be some sort of specifications to certain options he had. Jake had decided to move the slider up to 70% of his current muscle structure. He figured he wouldn't go too far just yet.
Seeing nothing else to adjust, Jake hit change once again. Suddenly, pressure started to build up in his legs. He noticed his thighs and calves have started growing and gaining density. Jake's legs have swollen and raised his hight an additional foot. The swelling reached around his thighs and to his butt. Jake blushed as his buttocks ballooned into bulbous orbs the size of basketballs. Still blushing, he sees his tail had also gained density and grew about an additional 4 inches, causing it to wag above his bubble butt. He then felt a bulge in his crotch area as well as he realized his genitals have started swelling, making him blush even more.
Jake felt the pressure move up to his abdomen, increasing its density. Jake had developed abs, continuously swelling until he had an 8 pack. His chest started to swell, balloon into the size of 2 massive beach balls. His arms and biceps started to grow and gain definition as well, leaving them huge and veiney. Jake flexed his arms a bit as they continue to grow. As his growth reaches its final stages, his neck starts to swell, getting more dense and veiney as it thickened. Moments later, Jake's body finally stopped growing.
Jake examined his new figure. Not only was he a human shiba, but he was also so muscular that any normal body builder would get jealous. The only thing that stayed proportional to his previous build was his head. He thought he looked kinda cute, having a small doggy head in a body of hulking muscle. The thought made his tail wag.
Jake's new muscles thankfully were good enough to accommodate the size of the doors, even though it might be a bit of a tight squeeze. After flexing a bit, checking out his huge body, Jake thought he would cool down with a nice shower. With a bit of effort, he managed to fit into the bathroom. He hoped he didn't have to shed any fur in order to keep the drain unclogged...
