Twenty minutes later, Tricia was again standing in front of her bedroom mirror. She had programmed the remote to her specifications and prepared to zap herself for the biggest change she would go through so far. She took a final look at her human self and pressed the activation button.
ZAP! For a few seconds, Tricia felt completely normal, but she knew that was fleeting. Soon she could feel the changes taking effect. Her entire body tingled as if thousands of ants were crawling over her skin. Black fur sprouted from every visible inch of her body. It grew thick and soft. Tricia rubbed an arm, feeling the fur crinkle as she pushed it the wrong way. She petted it back the other way to straighten it out and diverted her attention to other parts of herself.
Her face was growing a muzzle, exactly as she wanted. Her nose flattened into a triangular feline one, as a few whiskers and pointed teeth poked out of her face. Her pupils changed to slits and her eyes yellowed. Large semi-pointed ears grew from out of her hair, which was turning a rich black color to match her fur. It became luscious and shiny, which helped to distinguish it from the short ebony hairs of her fur.
With a strange pulling sensation, a tail slowly emerged from her backside. It grew a yard long and somewhat fluffy, especially at the tip. The nails on her fingers and toes turned into sharp, retractable claws. the heels of her feet rose up from the ground as she adopted a digitigrade stance, raising her height to 5'9".
The changes ran their course, and the panther-girl took in her new form in all its majesty. She purred in delight at the new sensations, the new sounds and smells that went unnoticed by her human senses.
She felt strong and sexy. Gracefully, she strode around her room. She flexed her fingers and watched her claws pop in and out. She whipped the air with her tail. She licked her muzzle with her rough feline tongue.
One downside she hadn't counted on was the colorblindness. It was strange seeing the world in black and white, but not so inconvenient that she desired to correct the condition with the remote. For now, she was more than satisfied with her changes and began to think of what to do now that they were finished.
