You know its kinda sad that Anne already had more exposure and character building than most if not all other female characters, what i mean is after "breaking" them you might as well replace them with rubber dolls and it wouldn't make much difference. I feel you stripped to much of the characters identity (as in all of it), personally i think it would be better if they were told from the start how the world is and have them slowly give in to their desires, maybe nudged in the right direction without breaking their character too much, something along the lines of "Rainbow assaulted a stallion that was bit too forward and gets locked in a chastity belt with vibrators filling her holes and an enchantment preventing her from cumming until she 'Apologizes' to him" or "Twilight is so engrossed in new magical/scientific research that she barely pays attention to other scientist plowing her" . The way you guys painted the world in the first few chapters would suggest that beside open stance on public sex nothing much would change and the mares would still work and have a life of their own outside of casual sex, but later in the story that was replaced by full out misogyny/sexual slavery where mares can barely have a breather because the stallions are sprouting semi-permanent erections and are almost constantly looking for a fuck. Overall the story and characters lack any depth (even for a clopfic), its mostly Sunny going "i'm gonna do this one, then this one, then that one..." and i fear no amount of porn logic can save it.

Later chapters what you want comes into play. It's just that the 'first season' of chapters are about gaining the first foothold in space and getting all the females that Sunny wants into the empire's mindset of being fucked. After that, they can go about their job that they were assigned. Heck, we are planning to give Daring her mind back so she can treasure and ruin hunt again. We just don't know how to put that into words yet.
