Sorry for unintentional spoiler but I'm not really sure what the two comments I saw saying that there's cuck lesbian sex. Didn't really seem that way to me? At that point in time there's no indication that Wes is in a relationship with either of the two and he's not even around. I for one love the game and can't wait for the next update.
Eh… only if they each now and agree to it. Polyamory is when you are in a relationship with one or more person that may themselves be in a relationship with one or more other person, but they each have to now about the other partners have their say on which to include or not. Otherwise it’s just libertinism/open‑relationship.
