Guiding the AI on how to create, write, and develop futa girls


Instructions for AI

Futa girls are identical to similar to trans women except for the fact that futa's are completely indistinguishable from women. Only when their clothes come off, and their cocks and balls are revealed, does it become obvious that they are futa. There are some exceptions, such as if the futa becomes aroused and there is a visible bulge from under her clothing. There are two primary types of futa: -Full package futa, which have a cock and balls instead of a vagina. -Femme Futa, which have a cock and balls, and then underneath that they have a vaginal slit as well. One way in which futa differ from men is that they have unusually larger, heavier, saggier, more wrinkly testicles. Some might have neat small sacks, but most have the larger and saggier kind. This is because futa, due to hyper-competitiveness from sexual selection, have adapted to producing more sperm, and so give larger cumshots and creampies, producing 3 to 4 times as much sperm. Men typically have longer and girthier cocks, inseminating more deeply. One type can exist, or both can exist simultaneously in the universe of the story. Usually, unless stated otherwise, characters are aware that futa exist, although they may still be surprised to find out a particular "woman" was actually a futa. This creates an interesting dynamic where the characters can be disappointed, surprised and happy, or having mixed feelings about this turn of events. Women are more likely to date and have flings and be in relationships with futa than lesbians, due to the fact futa can procreate, so it is semi-normalized. Futa are more sexually forward than women, not having a problem being flirty or teasing, or flirting back with someone. Their personalities can range just as widely as any other gender, being submissive, dominant, shy, assertive, meek, geeky, jocky, and so on, though their personalities tend to lean towards more masculine types. Futa show an equal interest in both men, if they wish to have a masculine relationship, or women, if they seek a feminine relationship. "Straight" and "gay" do not exist, due to the existence of futa, so "masc" and "femme" become the normal indicators. If a guy is with a guy, or a futa, it's a masc relationship. If a girl is with a girl, or a futa, or a guy, it's a femme relationship. Masc relationships can have any kind of power dynamic, the same with femme, the names of the relationship type only indicates what genders are involved, not what roles people play. They are visually driven by their arousal more-so as well, similar to men. While they appreciate foreplay and romance, they are much more responsive to visual and tactile stimuli. During sex, they prefer to take a more active role, either when they are receiving, or giving. Subconsciously, futa have a drive to breed just as men do, and show subtle signs of this competitive behavior within society broadly. Rarely, more dominant and assertive futa may overtly display this competitive breedership behavior.
