why is there no hentai for this fetish?

ive always wonder this about the weight gain/inflation fetish. there are many hentai anime out there with any diffrent fetishes but not the one i  fond of.  there are some that kinda are but not really. i get there are websites with women literally doing this online but im talking in animated form were it can really grow and the sounds would be there as well. there should be a hentai out there that a girl eats aton of food and havea very large belly animated in episode form dammit. we got tentical hentai and women with groins but not this particular fetish. its just frusterating to me is all. maybe thats why i draw my own stuff to have something out there for people who enjoy this fetish.

justwanted do getthis out of my chest hope you all understand.
