A friend of my friend who knows a neighbor who knows Lisapi told me that who knows.
The story is very long behind that but in short: Pregnancy will exist in hardmode by default as a punishment and in normal mode, you will be able to unlock it but also a punishment will be applied.
I still have to define everything and I won't talk about this in detail until the public version (I'll probably do it on Discord in my spoiler channel and the diaries on Patreon).
This will be implemented in the v0.9 and I'm still finishing the beta of v0.8 so at least until January-February next year I won't implement it.
Its function will be very basic (as a punishment) as there will be the possibility of girls getting pregnant and it will penalize you in a way that after having sex with them several times while pregnant they will go into "cd" and you won't be able to have any sexual interaction with them. Initially, this only includes the main girls, eventually, I will see if the secondary ones will be included as well, mostly due to the fact that this requires a lot of time and is not something demanded by 100% of the people who play LA and it's not my thing like pee/feet.
Additionally, I have to think very carefully about how to integrate this logically as there is the blessing of Aynia at first, but that's easy to solve. I have to think very well on a lore level in the world of LA the whole process from when a girl gets pregnant to when she gives birth to the baby and "magically" disappears and so on. This last part is the one that I know will give me the most headaches because for me it makes no sense that things magically disappear or that you totally disregard any responsibility based on the premise that the MC is on an adventure to become a person almost as responsible as the king of a kingdom. But well, these are things that I will discuss with different people who understand more than I do about this fetish at the level of lore.
As a final note, although you can have sex with the girls during pregnancy, it will be a totally optional thing to watch. I'm not going to force people to watch something they don't like and I'll separate it like the other fetishes. Although the punishment on hard will stay, you simply won't see anything and the girl will go straight into "cd".
But almost 100% there will be no achievements about this particular fetish or backgrounds, etc as it's not my thing but as the idea of implementing it as a punishment seems funny to me I'm going to implement it. Of course, there won't be any weird dialogues like you can read or watch in doujins/videos. I wouldn't feel comfortable writing that kind of dialogues but I respect everyone's taste.
There will obviously be ways to avoid pregnancy to avoid the punishment but as this is something I haven't even thought about I can't elaborate on it.
