So tried the game and seemingly got every route finished except for the mom route, it at first told me it was complete but then I could get a jerk off at the couch with her and then I could keep peeking on her, then the game told me to see her at dinner but I had already done it and the next time I tried it went for the sis, is there no further content on the mom or is it just that the game prioritizes katie? Also talking with Olivia at school or messing her seems to somehow start the mom interactions instead once your far enough on Olivia route.
