This thread has been a huge help for myself in getting a handle on how FMG ‘works’.
BE tends to be a ‘passive’ power effect… as the protagonists gets bigger she gains more attention.
FMG tends to be an ‘active’ power effect…as the protagonist gets bigger she can now go out and get what she wants.
... For instance it can be very erotic if an FMG character, kept on growing as she was having intercourse. The desire to want more, begging for the partner to make her bigger, which in turn causes her breasts to swell, her nipples to become erect, her clothes to rip, her muscles to bulge, and her body to grow in general.
...
I have seen this theme before. It’s very established in most kinds of Size Fetish fiction, Arousal = Size has always been one of my favorites.
And as I read more and more of this forum I’m starting to notice that FMG/GTS readers are fare less forgiving than BE readers. FMG/GTS readers need more than growth only, if the story lacks ‘Mental Design’ from the main female protagonist, the reader gets bored and finds something else to read.
My question: would the following story premise work for a FMG story…
A space explorer crash lands on a forbidden planet. He discovers a female alien who wants a ‘one-night-stand’ before she kills him. He refuses and flees back to his ship. The story continues with the female alien undergoing FMG in order to surpass the ship's defenses and get to man. As long as the ‘cat-and-mouse’ elements of the story are done well… where the explorer does what he can to stop her, and the space alien does what she can not to be stopped… then this could satisfy a FMG reader’s expectation?
