Sarah looked over at Mandy who was meowing weirdly. Her Black fur was getting longer and it changed to Red. Mandy's Tail got storter till it totally disappeared. Her hind legs straightened and her feet started getting longer. The fur from her hind quarters started moving up her body to her head forming a Mane of hair. The cat started to gain mass, the little cat had doubled it's size and almost looked human. Her back legs straightened more and so did her back till she was able to stand up staight. Her paws formed into hand and feet with 10 fingers and 10 toes. HEr shoulders pushed back and her cat nipples disappeared, leaving her with only 2. Sarah looked over the little 3 foot tall girl. It was like a little mini me she though to herself.
The little Red head looked up at the 6' giant, she was confused. What was happening, information was flooding the cat's mind. She kwen she wasn't a cat anymore and her master didn't look as bis as she had before.
The changes were far from over, Mandy started to grow faster, her hips widened and her thighs became smooth. Her breasts enlarged mounds formed under her nipples growing and rounding finally stopping at a Double D. Her legs lenthened and her body stretched till her height topped out at 6'. There in front of Sarah stood her naked identical twin. MAndy picked up the Mini skirt and tight top off the floor and put them on.
'Looks like you're not my master anymore' She said with a smile
Sarah didn't know what to do she didn' have any clothes that fit for herself let alone both of them.
'we have to change back' Sarah told her twin
'NO!, I won't go back to being a cat' she cried.
