"I suppose I could be nice and give you something to eat" the witch said. She waved her hands around for a few seconds while mumbling something in a strange language and suddenly a trough appears with different kinds of food in it.
"Well, enjoy your meal" the witch chuckles.
Christina still a bit dizzy pushed herself up from the floor. Still naked she kneels in front of the trough.
"This is so humiliating" she thinks, but her tummy seemed to think otherwise because it made a loud rumbling sound.
"Oh good, you are hungry, dig in" the witch chuckles again.
Christina tried to ignore the witch and took a small sandwich out of the trough and took a bite.
"Oh my, this tastes actually really good" she thought.
While Christina was eating, the witch was casting another spell without Christina noticing it.
Christina grabbed a burger from the trough this time. She didn't notice that her ears started to get pointier and that her nose started to turn up slightly. While eating her ears got bigger and a bit floppier and moved a bit further up her head. After finishing the burger she had perfectly shaped pig ears. She grabbed another burger and this time it was her nose' turn. With the first bites it just got bigger and her nostrils started to expand with it. But as she continued eating her nose took more and more the shape of a pig snout.
Christina still unaware of the changes spotted half of a cheesecake in the trough. Her eyes started sparkling and her piggish tongue leaked over her piggy lips. "Come to "oink" mama" she grunted. Totally focused on the food she didn't even bother to use her hands anymore, she just pushed her whole face into the cake and used her new snout.
To do so she had to bend over the trough, exposing her bare ass to the witch.
The witch watched Christina getting more and more piggish in delight.
"Perfect timing as it seems" the witch giggled. Right above Christinas ass a little fleshy knob started to form and while her ass started to expand the fleshy knob grew into a nice little curly pig tail with a small tuft of hair at the end that matches Christinas hair color.
By now more and more grunts were coming from the trough.
After the curly tail was finished her asshole and vagina moved a bit further up between her now bigger butt cheeks which made her wiggle a bit from side to side.
And while her feet already were hooves her hands were still mostly human as was her shape apart from the pinkish skin and the pig bristles.
As Christina developed her additional teats the witch said "You know I think I will keep you like this, that way you can serve me better".
The witch snipped and a little spark flew at Christinas ass which made her head shoot up in confusion. Her snout was full of crumbs and creme and she looked up at the witch.
"My what a messy piggy you are" the witch chuckles.
Christina just realized that she had been transformed again as she was looking down on herself, seeing the additional teats and her new pig skin and most prominently her snout. But she was just half pig, she still had hands and a more human like shape.
"Oh my god "oink" what did you do to "grunt" me?" Christina grunted.
" Now now little piggy, calm down. I have more plans for you" the witch said in delight.
