Gaining

I've had a weight gain fetish since I was in jr high and my current girlfriend of two years has always been kind of vanilla. However, within a couple of months of meeting me, I slowly came out to her about my sexuality and she let herself go a bit and gained about 50 lbs. After I realized she was cool with it, she indulged me and humored me while I did weight gain talk during sex, jiggled her newly fat body and occasional feeding sessions. Now, it seems like she only gets wet (or at least gets wet a lot faster) when I talk about how fat she's gotten, jiggle her belly, and so fourth. I also do a hypnotism RP where I tell her that once I cum inside her, she's going to get turned on by her own weight gain, become more content with her weight and lose inhibitions to not indulge in laziness and snacking. I don't know dick about hypnosis or conditioning, I just kind of wing it, but it turns her on immensely. She even told me she has to jiggle her belly when she masturbates now.

Can a fetish be developed later in life? We're both 24, I love what we have now, but I'm concerned that if we ever split up she'd be stuck with a feedee fetish permanently. Has anyone ever encountered a similar situation? Do you think it would wear off over time?

Wow, you are so lucky! Marry her, then you won't have to worry.

I think a Lot of people have it but it remains suppressed. I know of two women in their 20's who had small weightgains of just five to ten lbs and went right into substantial gains immediately.
I don't think the true fetish is learned. I think it's just there and sometimes gets awakened.
Congratulations btw .

This.

Sometimes vanillaeans vanilla....sometimes it means hasn't discovered or accepted what really turns them on.

So....I wonder if they liked the gain and tried to gain more or did they just get used to eating/along with metabolism changing and really started packing it on lacking food choice and portion control?

Could be either way. But some definitely realize they like it after an accidental or experimental gain. E.g., Cherries (ex-Big Cutie) gained a few pounds for her bf and then found she liked it herself and gained quite a bit more.

The two I'm thinking of liked the initial small gain. The first was a five lbs gained at Thanksgiving followed by her first time of not making any attempt to lose it back..Then I would say the next portion was experimental gaining 15 more by the beginning of March when the stuffings to gain started and in 6 weeks another 35 lbs landing at 170 lbs@ 5'3" by mid April. And 200 lbs by late June. The other person is still active so I will leave it to her if she wants to comment .
