Some people didn't like dinner at Ethan's, because Emily and David went away, but I wasn't ready to put Anna in a foursome gangbang, maybe it's just me. Don't worry, though. She will get more exciting action in the next update.
I don't think that people were expecting an orgy to take place at Ethan's, just that if any sex occured, it would all take place in the same room.
For example in the upcoming poker night with Anna and Emily and their 2 coworkers, if the game ended with some sex, it could be Anna and Emily getting fucked from behind, with the 2 girls kissing and fondling each others tits while they're getting banged.
