Did I choose something wrong with Bri and Kim?
There's no "wrong" in this game, there's just logical consequences of your player's choices.
It is definitely not a game where you can get every scene in a single playthrough - sub vs dom or romance vs sexfriend is the main differentiator for most girl's routes but there is also some route-interaction across girls (cheating might block stuff etc)
However I know that's not very helpful if you are trying to get specific character scenes so:
- there's not as much Deb content if you go the Bull route, but there is some (just later than the beach house)
- you need to have made some sympathetic choices in conversation with Bri to get her beachhouse scene. In general there isn't as much content for Bri as there is for other characters yet.
- Kim routes (pure-Sub and evil-collaborator) require you to make certain choices in the cafe scene, sounds like you made one that closed those routes off.
One way to play that I've seen mentioned is to try multiple playthroughs with different MC "personas": subby, dommy, manwhore cheater, dedicated to specific girl... etc. There is a LOT of branching and differences depending on earlier choices - someone posted a few pages back that even after multiple playthroughs they only had "90% content viewed".
