Story authors

Hi;

I've been looking for a story I remember liking. I don't recall it being long, but it compelled me.

It featured a woman framed for a crime she didn't commit and imprisoned and fattened as punishment, while the woman who actually committed the crime gets to inspect her as part of her "victim's rights."

I thought it was on here, but I can't find it with any search terms. Does anyone know this one?

Thanks.
