Mary snickered and childishly grinned as she came upon the Fox vial which was still unused to this point. "Welp, bottoms up!" Uncorking the vial, she chugged only half of it, still wanting to have some human features after the change.
She wasted no time in bouncing back to the mirror, accidentally doing a little somersault too since she was so light and filled with air. "This'll be fun, " her reflection was just the same as before, quite a stunning attractive rubber doll that can move and talk but otherwise not very huggable, that soon changed as she saw the area between her two huge breasts change color slowly, turning whiter by the second, and it was spreading fast. Her hands rubbed them in anticipation of what other changes will occur, and just as she was doing that she felt something change directly underneath her snowy globes. Four little bumps appeared beneath her jugs, and they were growing fast. "Ooh, more fun!" Her hands ran down her breasts and soon reached the first two bumps, which she tweked in her fingers. The pleasure was incredible, and it steadily increased as she felt mounds begin to build underneath them, soon approaching a size a bit less than the ones above them.
Elsewhere on her body, other changes were taking place, her mouth started to tingle a lot as it slowly began to push out into a foxes muzzle, the color there changing to a red. Her ears twitched each time they grew a bit more, and migrated up to the top of her head. A playful growl emitted from her mouth when she opened it, just as her new rubber fangs grew in. "I look soooo cute!" She couldn't help but giggle at her ridiculous new form which was still changing shape.
The feeling soon spread to the region right above her butt, she now started to inflate out, her new rubbery fox tail also swelling out wider and carrying the same red color, only with a white tip at the end. She had to sit down as she continued to fondle herself, the pleasure starting to become a little too much to still stand up. The rubbery hands which she was rubbing herself with soon started to turn a deep shade of brown as her fingers plumped out ever so slightly and thick rubber pads developed on her palms and bottoms of her fingers, which only did to increase the euphoria she felt when rubbing her still growing assets, which finally began to slow down growth wise.
Her attention soon shot down to her rubber feet, which were the last things to change on her, and since she had a slight foot fetish with herself, she wasn't too sure if she could contain herself. A moan escaped her mouth as she felt them swell out, lengthening a bit with each second, her toes plumping up to look more like fox paws, and the same pads on her hands developed on the bottoms of her toes and on the balls of her feet.
After the feelings stopped, her new paw-like hands haulted with the carresings for the moment as she stood up, noticing that she was now standing on her toes. Looking at her reflection in the mirror a few times and turning from side to side to get a better look at herself, smirking as she thought of some other way that she could make herself even more adorable.
