As Jess realized that she was really turning into a pig, she felt her nose turn up and into a pig's nose. Then she felt a curly little tail trying to get out of her panties and pants. Finally she gained weight... A lot of weight, as Jess was expanding, the button on her blue jeans popped off and her stomach was pushing her fly down.
Mary could only stare in amazement.
"Jess, you really are a pig. Don't worry, you only drank a little bit so you won't completely become a pig."
Then both girls heard a rumbling and figured out that it was Jess' stomach, she wanted more food.
"Be back in a moment Jess."
Mary soon came back with two containers full of ice cream. She placed them on the table and opened the lids.
"Dig in."
Jess grabbed one of the containers and tried to eat the ice cream. As Jess was eating, she was getting bigger. She was half-way through the first container when her jeans started to rip.
