Watching myself grow into a barely mobile person, heavily pear-shaped; not sure if I'm still a guy or changed into a gal. Definitely looking like an ssbbw.

Yes, kidnapped & fattened until I obtain a sufficiently womanly shape.

So fat that, that I look more like a woman, than a guy.

Yes, I like to RP.

I like m2(ss)bbw. Either trading places with an ssbbw. Trading places with a woman & then getting bigger; or having women add their weight to me until I actually look like a very fat woman. Or something similar.

I knew of a gal who came home to her 'boyfriend' having sex with another guy. It was his way of letting her know he's gay. She got very depressed & went from 170 to 280 in 9 months(no pregnancy).

I'd like to do either or both.

You need a bigger belly, hips/ass, & teats.
