FatAsButter:
The limitations are a big part of the drive to gain, for me. Like having to lift my belly into the bathroom sink so I can reach the window, otherwise it gets in the way because I've grown so large. I'm ten stone/140lb over my maximum healthy weight, so carrying around what is double the weight of an average person limits walking a lot but that just turns me on and I plan life around being inactive, eating and growing. I Iove literally not being able to get through gaps which are pretty big. Like not being able to walk a particular way because it has a kissing gate to stop cows getting through, but it stops me. It's not even like I could squeeze past - literally no chance at all. Being almost unable to reach to use my vibrator just makes sure I am really aroused. I don't like being teased over my weight, to me it's a choice I've made and an ongoing achievement rather than a weakness. In other people, videos of men and women really waddling about or just even struggling to leave their bed is really hot. I'd love to feed someone to 400+ lb and really push them into it, filling their belly to the max and doing weigh ins and measuring etc I'd really enjoy seeing them balloon out and get to the point of relying on me to cum because they couldn't reach past their fat.
This sounds like fun, I think the only way I would get so fat that I have to depend on someone else in that way, the other person would have to really enjoy it as well. But would be open to it.
