I’ve Completely Ruined My Girlfriend’s Body

I’ve completely ruined my girlfriend’s body by enabling her. She has no control over herself, and I exploited her weaknesses. She used to be very active and ran almost every day. I started negging her and telling her she was too skinny. I started pushing her to eat more, and I constantly brought her fast food and sweets. She weighs 288 pounds now, and all I want to do is make her even bigger. I am not fat at all, and people are shocked when they find out that we are together. She whines often about becoming way too fat, but then happily becomes a glutton and eats the feasts I put in front of her.
