First, in the end of the game. Second, you may see her pregnant now in the game as a joke.
Her pregnancy is intended by her storyline, which will happen closer to the end of the game. For now, you can see her pregnant in the cellar.
Also, maybe we'll add one pregnant sex animated loop to an early scene as the girl's fantasy, just to tease the player and don't make him waiting for the whole game.
I wanna check that out however I wish that could be built up to story wise with into the wild..... It would be really cool to see naira end up pregnant before the end of into the wild. maybe have a branching storyline with Naria where 2 different paths will have some kind of impact on the relationship between the charcter the player is controlling and Naria
