It factors into my fascination and fetish for ruination. For me, what really turns me on more than pretty much anything else, is ruining a character’s life, body, relationships, future, etc. So weight gain, to me, is about forcing a character to ruin their body, undermine their health and their abilities, all in the pursuit of short term satisfaction, pleasure, and hedonism.
That said, and this is a bit odd given my other interests, I’m not actually super turned on by extreme gaining or immobility, and I have a hard time articulating why, exactly. To me, the real sweet spot so somewhere between 400 and 500 pounds, where life can become a real struggle, but if that character sets their mind to it, they can still do everything they used to do, it just takes so much more work and energy that they no longer have. It’s a bit of a mind game to me, I suppose.
