Looking for story or site i saw it on

It was a weight gain story and it was a multi-part one that was very long. It was on a website which had other growth related stories, many of them also pretty long.

In the story, the girl gains weight very slowly. I believe it was because of a spell a Wicca fellow student put on her. There was some magic jewelry, like a ring, and the wicca girl would change it to the body part she wanted to get fatter on the other girl.

Thanks if anyone knows this.
