>>40494She was already quite chunky, so I told her from the start that I like BBWs. I avoided this in the past, but being open and honest about your preferences work best. With my first wife, any tummy touches or mentioning her chunk would immediately turn her off because she would immediately feel insecure. Being honest about this from the start either (1) weeds out women where there will never be any fat-play allowed or (2) allows her to feel comfortable when you touch the fat, talk about her fat, etc during sex.
From then on, it was just operant conditioning. Basically, the more she stuffed herself, the more I focused on her pleasure. If, for example, she started a weight-loss diet, I stopped initiating sex with her, and when she initiated it, we neither of us would cum. I told her I'm sorry, that I was there to support whatever her decision was, but it would take me time to get used to the situation and be able to maintain a hard-on.
When she would finally cheat on her diet, that's when I would reward her. Naturally, I was 100% aroused, which turned her on, and I told her directly what was turning me on. Seeing her indulge herself like that really does it for me, etc. Then, as her climaxes would build, I'd get dirtier and dirtier. You can tell when her orgasms are getting more intense. That's when you tell her (after she's comfortable with it, of course) that she was meant to be your fat fucktoy, that stuffing her until she's ready to burst then fucking her brains out is her only duty, and eventually that that's all she will ever be able to do, get fatter and please you because she will be too fat to and too helplessly addicted to food to to anything else. As long as she is open to it, and you progress to that point slowly, pushing the boundaries little by little, eventually it will become her fetish as well.
I also kept her hooked on both me and our feedings with drugs. This is the part that most people would probably object to, but I dosed her regularly with F-Phenibut, about 50mg every 8 hours or so in her Crystal Light. When she would stuff herself more, I would give her more. When she would diet, I would restrict her intake. This drug is highly addictive, and those intake differences can feel like life is terrible, everything is bad, and you get 0 joy or pleasure out of anything just by reducing intake from 50mg to 10mg, or like you're invincible and have no troubles in the world and everything is perfect by giving 100mg.
This part, however, is tricky. I finally got her off F-Phenibut, because it's not a long-term solution, but it took over a year to do it. And she never even knew she was taking anything.
My current wife and I met when she was 220 pounds, up from her low of 190 and down from her high of 280. Over the next three years, she gained up to 310, then down to 270 then back to 300. We got married with her at that 300 pound mark. We've now been married for around four years, and each year she's gained about 25 pounds (on average). That first year, she gained 40 pounds, then she gained 30 the second, then she's plateaued at around 400 pounds for the past year. But now, she's genuinely into it. She is always eating and drinking junk and cannot cum without being overly full. She cums the hardest when I reach the deepest, darkest levels of fat fetish depravity. She really is helplessly addicted to food and her fetish now to ever live a normal life.
