Gluttony Parents (Patreon)

Is this anything? Years and years ago TheKoudelka did a series about a young woman who goes from a fit soccer player to immobile mound of fat when she discovers junk food.

For reasons unknown I came up with the idea of turning the tables and making her parents get extremely fat.

I could have gone into more detail, but since this was only a silly fancy I decided to do little more than rewrite the descriptions Koudelka had already written.
