You'll have to finish other quests and up your stats with the family until you progress with your mom enough to where the guide says you should join the gang. Once you reach that point, you can meet them at 9PM in the living room, and join them. Afterwards it will take some more progressing before you get the final part of the update.I'm at the stage where 3 guys are sitting in the living room and my mom is naked, the guy asks if I have money, he pays him and this scene repeats every weekend. is this the end of this update or what?
