First of all thanks for the fast answer. Sorry for the confusion, what I meant is the difference between being impregnated (having belly) and getting impregnated (with talk like being on a risky day or not on pill, etc).
About her body getting "used/reprogramed", I meant like overcoming safe days (like a villain) or interspecies. She wouldn't normally get pregnant in normal instances, but since she has powers her body could be "reprogramed" to be able to get pregnant, since it enhances the corruption theme. Hence why I said it may not fit the game yet, and it seems in a way the idea was similar, since you spoke about endings. I wasn't specifically talking in getting pregnant over and over, but actually wanting to be able to, as a final decay on the taboo and/or societal constraints.
Since her pheromones are already "stronger" because of Reinar, that in a way can be seen as a "reprograming" or "adaptation" of her body to him for example. Hence why in my mind that would fit the game in the future, but still wasn't sure because I have no idea of your final goals to the game. And while there are kinks that I like to see in game, unlike others I try to see if they actually fit or not the game, hence maybe that's why I didn't explain myself well above.
Sorry again for the confusion above, and thanks again for the fast answer.
