@Jonhddd well you kinda right onto that but all the whole busty to the point also goes no where just grow grow grow oops im the say of the universe i dont have a equal partner or even think about how to much it just a pain for hunger and also movement .
It basically when you think about Growing i use a bit of what could be a problem for them One is hunger eating people will never fill the person up if there size . Two is movement will be hinder if it to much muscle or bloating . Three is having a partner to actual pleasure because on you basic like tick to them or flea but growing to size of a milky way would make molecule of pleasure to that person which they wont be satisfied. Lastly four loneliness because no interaction ( Wilson Wilson) to prove my point.
I've seen plenty of these where there could be partners going at it while huge. No chance though for whatever reason. This strip for example. What's stopping the bird and the bee?
I got nothing against the growth fetish. Just sometimes I wish it was more then "pinup" material.
