I do have a weight gain fetish, but I have not intentionally tried to make my wife gain weight. She did it all on her own, and I love it. I wouldn’t call myself a feeder and her a feedee though. It’s a bit more complicated than that.
She’s Vietnamese and immigrated here for school. Super short, about 4’11. She was stick thin when we met, due to Vietnamese beauty standards and family pressuring her to be as thin as possible, she weighed I believe 90 pounds when we first started dating. She’s always wanted to be a mother though, and noticed that a lot of mothers, at least in the US, tend to be kinda fat. So she decided she wanted to gain weight to have more of a “motherly figure”. It wasn’t so much of an intentional weight gain as much as just her no longer restricting herself when it comes to eating. Fast forward four years and she’s 220 pounds and counting now, after one pregnancy. And a lot of it isn’t even pregnancy weight, she was already like 190 pounds when she got pregnant.
Again not even done through me pressuring her, although I have always told her I will love her no matter her weight. I do find a lot more attractive now that she’s bigger compared to when we first met, though
