Yea Inoda and Asuna won't spend the two weeks fucking. Asuna right now doesn't trust Inoda and setup cameras to catch him if he tries something on her. He has cameras to catch her too. But since they are trapped together she will get used to his advances. Even now she no longer minds his smell. A lot more IRL foreplay scenes are cumming. Hopefully it will lead to IRL sex and finally breaking the 500/500 affection limit!
Also they can get condoms from the hotel. They usually provides them.
The first week probably not. The 2nd week though? It's probably happening on the 2nd week. This update more or less just sets it all up for Asuna to just get extremely horny by any means necessary. Using the PTSD doctor's note to explain she'll get more addicted through further stimuli, and how we know that FOG just enhances your desires to do it IRL. And then also Inoda getting cheat magic sex items that for whatever reason he can mark it on Asuna, so now she'll get hornier even faster in-game, which should also translate to IRL.
There doesn't really need to be a lot of foreplay scenes to begin with. Just a lot of sexual frustrations building up and probably bumping into Inoda while he's naked enough times will trigger her horny instincts to just go for it. I would be most impressed if Fujino makes Inoda do very minimal IRL foreplay to write out the simple narrative of building up Asuna's sexual frustrations.
Since the next update is the big battle update with minigames, it's possible that a lot of the IRL progress can go by a lot faster. But it depends how much the FOG events effect Asuna IRL to speed things up or not.
As a side note, I don't know exactly what Fujino wants to do, but the whole Leafa getting access to Kirito's base, and Sinon wanting multiple meet ups with Kirito will probably be the "distracting activities" that Kirito will be doing while Asuna is busy getting railed by Inoda in either FOG or IRL (either foreplay related updates, or just banging). This also leads me to believe that some people who think that the 14 days are just going to blaze through on the faster side could potentially be right. Since both Asuna and Kirito are in a position where they'll constantly have reasons/excuses to be away from each other, this will decrease dialogue and just increase more scenes. Like for example I'm thinking that maybe Asuna does something similar she did this update where she didn't trust Inoda to do something funny to her, so she logs off earlier than normal. The point being that the interactions between Asuna and Kirito get shorter, so more of the banging happens sooner on potentially both ends (cause Leafa gonna do something in Kirito's base).
