One thing that would be cool in this kind of game would be if the "slow corruption" path is somehow rewarded. Being more immersive (as in you make decisions that actually make sense instead of running to the closest rape-trap) I guess is a reward by itself, but it would also be nice if the path taken would have an effect in terms of some stats or traits.
For example, if you push her just slightly out of her comfort zone consistently, she could become more excited about various degenerate things, whereas if you push her by getting assaulted/raped, she instead becomes more numb. Both would eventually lead to everything becoming less traumatic, but actually enjoying it rather than being numb to it feels like a reward of sorts.
That being said, one cool thing that could be possible if stats/traits would allow for it is her being aware that she is putting herself in dangerous situations, and the ability to act traumatized during them, with inner monologue thrown in where she is actually enjoying it. Obviously this has porn logic written all over it, but that's sometimes a good thing.
