I've been looking for this weight gain story which I believe also had breast expansion in it. It had multiple parts and it was on a post in a forum, I had thought it was this forum, but now I'm not sure. It had multiple women gaining weight in it, via this product that the main character and his associate were giving them, that was like drinkable cream? In the later chapters, all the girls end up on a farm I believe. There is also this one part where two of the girls have to get into a vehicle but they have a lot of trouble because of their size.
Sorry if it's very vague, that's all I can remember.
