I thought about being something related to scene head-hopping but since the transition had no time reference could go either way flashback or a point in the future after the original scene.
Indeed it's silly, but considering the plot slow pace/burn i can't see Fujino making Asuna having sex at Inoda's place so soon or in the office, these scenes will take place for sure but not right now, remember in last update she didn't wat to go to the hotel with Kirito just to avoid the chance of meeting her mom it's about plot consistence and Fujino's plot conveniences.
If this apartment came to be i don't think the justification will be only fa secret place for sex with Inoda but since her mom it's way more relaxed with her why not she start living by herself and she could have tthought having a place would be easier to meet with Kirito, before the last update of course.
And about new maps/location this is far from a possible solution, but Fujino is already doing that just check the last updates scenes, Bath, Motel, Cave Battle, Brothel and so on Fujino never care much about the size of the game, it's only a problem for him now exactly because of that.
