Fattening others

Hi everyone, I’m looking for some advice on how to introduce my girlfriend to the feedism kink in a respectful and sensitive way. We’ve been together for three years, and so far she hasn’t shown any interest in feedism. Over time, she’s unintentionally gained about 30 pounds and has become quite self-conscious about it, even though I’ve tried to compliment her and reassure her regularly.
I want to be open about my interest without making her feel pressured or uncomfortable, especially considering her feelings about her weight. Has anyone been in a similar situation or have tips on how to gently broach the subject? Any advice on timing, wording, or approach would be really helpful.

I told my girlfriend last year, you just need to be completely open and honest. As long as she is a good person she will accept it. Whether she decides to take part or not you will have to find out.
