Kyle fell backwards as his legs went numb, he watched in shock as they started to shift and change, growing tan fur and gaining muscle. Markings appeared on his thighs and he realized that his legs were changing into those of his fursona, Zander.
Zander's character was tall, seven foot, muscular and well hung, with a foot long cock. He was a lion, who was the exact opposite of Kyle, popular, tall, sporty and strong. He watched in fascination as his feet shifted into digitigrade paws, muscle piled upon his legs, making them thick and strong, a tail sprouted and quickly grew to it's full length, after the changes finished he thought he was done when the legs started to grow larger.
Kyle stared as his already larger lower half got even larger, his new feet shifting position as the growth continued he hoped it would stop soon, but it showed no signs of slowing down, but just as soon as it started it stopped and he stared at his massive lower half. Kyle originally stood at 5'4” tall, his new legs were taller than he was originally, a staggering seven feet tall from paw to hip, he stared at his legs, leaning back against the bed, his feet planted on the ground. Kyle took in the awe inspiring sight of his new muscular legs, his thighs were thicker than his torso, he lifted his foot and brought it closer, touching his pad he marveled at the sight, never in his wildest dreams could he imagine he'd actually see this in person.
He suddenly stopped and looked down, he had Zander's cock, but how big was it now? He stared playing with it, getting it hard, he had to know what the size was now. He caressed the over sized head of his cock as it woke up and finally got stiff, pressing itself against him he gasped, his cock was thick as a two liter bottle of pop, and now almost three feet long, he was eye level with his cock head now. Kyle laughed, Jen meant to punish him but she gave him one of his greatest fantasies, now he had to live with this for a year, what a year it would be!
“No time to play with myself, I've got to go to school.” Kyle said to himself. He got up, and bumped his head against the ceiling. “Right, taller now.” He looked down and giggled, the muscular lower half proudly standing underneath him filled him with delight. He got his backpack, remembering that he could go naked from the waist down, and with fur now he wouldn't be so cold, winter might be a problem, but he had time to figure that out. He ducked out of his bedroom and gasped, the house had changed, the ceilings were higher, he looked back, the door had changed as well, it was taller, enough that he would still have to duck but not as badly. He walked down the hall, each step giving a slight thud due to the weight of his new form.
“There's my big boy!” His mom said, “Hurry up! You're going to be late for school!”
Kyle quickly ate a breakfast that was twice the size of what he'd usually have, he figured it was to fuel his physique, and went out the door. His new house was a single story bungalow, he looked around.
“We live in the suburbs now? Nice. I'll have to thank Jen for this!”
Kyle started walking to school, his new feet feeling a little awkward, as if he was on his tip toes, but he enjoyed every second, his strong lower half making him feel great and powerful, he couldn't wait until he saw Jen again.
