"I wish you would change me into a REAL bunny girl, like with this sexy human body but realistic furry rabbit ears, tail and muzzle, and paws instead of hands and feet!" Zach said, thinking that should cover everything. He turned towards the mirror on the back of his bedroom door to watch the changes this time.
Gene nodded "Your wish is my command, master."
Immediately Zach felt his body flush, a tingling sensation racing from his head to his feet before centering in the spots he mentioned in his second wish. His ears pushed outward, elongating as short white fur sprung out to cover them. They stretched towards the ceiling, quivering as new muscles formed to allow him control. His nose twitched, drawing his attention down from his new ears to find that long whiskers had sprouted above his upper lip, which was puffing up as more white fur spread over his nose and cheeks. His nostrils flared before compressing to angled slits, his lips disappearing as his lower jaw shrunk and receded. His eyes rounded as his pupils and irises grew, the colored parts of his eyes subsuming the whites and giving him an adorable bunny face.
Zach bounced and clapped, loving the changes to his appearance. Little squeaks escaped his muzzle as he hopped in place, not realizing how easy and natural the motion felt as his feet elongated and shifted him to a digitigrade stance. He did notice the changes to his hands however, as his clapping was almost immediately muffled. More fur had sprouted on his fingers, somewhat concealing the fact that they were rapidly shortening, his thumb disappearing as soft pads grew under each digit. He twisted his wrists, delighted by his new paws.
Finally the tingling focused on his lower back as his spine pushed out to form a new tail. Zach turned to view the changes, watching with glee as bushy fur puffed out to form the most perfect bunny tail he'd every seen. And it was His! ...or... Hers? Her paws brushed up her slender torso, encountering her new breasts, lightly brushing over her sensitive nipples. She lowered one paw to cup her sex, surprised despite her wish to encounter a smooth mound and slit where her manhood had been only minutes ago.
"Oh Gene, this is perfect!" Zach squealed, her voice high pitched and adorable. "I wish..."
