I am not sure I like the narrator voice acting. At first it felt a little bit cringe to me, but I couldn't point my finger at it. But then, few days ago my girlfriend set with me while I played and when she heard the narrator she started laughing. When I asked her what's so funny she told me that it sounds like the narrator is having sex, like she is talking to someone she is in the bed with. That observation totally ruined it for me lol
Thinking about it, your assessment can certainly be seen as sound logic. I think it can be seen as sexual or at least seductive and I think it is fitting when you think about the context. The voice appears when the larvae connect with you or with each other, which can absolutely be seen as a sexual or intimate act. So a soft female voice with added toughness or dominance is very accurate.
