Hey, glad you are enjoying the game overall. Pregnancy content is kind of hard to implement outside of narrow events (imagine, for example, having to check for pregnancy in ALL scenes and either make sure they aren't accessible while pregnant, or that they have dialogues and CGs to match, it's a ton of work for almost no pay off), even more so because I didn't plan for it in the beginning.
As for the scene you mentioned, I can't remember it off the top of my head. Do you think I could get away with showing naked Erica with her pregnant belly or would it need new art?
In theory, I wouldn't mind writing a couple more scenes with a pregnancy theme,
but it's low priority at the moment. Since I am trying to wrap things up, new ideas generally get pushed to the backburner and might only get worked on if the situation aligns perfectly.
