Well, Fujino can do this scene as a prank, since in the first part there was Asuna in the FOG with Inoda with his dick in her face while taking a selfie, but she was with blue hair and an elf, and in part 2 she is like normal Asuna in Inoda's recording and diary room.
It could be that this is after the massage and goes to the house where Kirito and Asuna teleport there, that's my theory. But in this scene there is a balcony and a lit room, it seems to be a Hotel in real life, I don't remember if Inoda has a lit room, and Asuna's room is too small to be her house, I believe it is in the Hotel or FOG itself which Kirito signed off and Asuna and Inoda were no longer in the massage room.
It's cool to see people's thoughts here, but in my head I think that's it, we won't know until the game comes out and finds out, since there will be 6 scenes in the game, so we'll have a lot of surprises.
