I think part 2 will end with real life sex this time, somehow gets stuck at Inoda's place again and I hope he tries the candle drug route again to get her going
I hope it doesn't end with them being trapped in Inoda's apartment again. But I'm confident Fujino won't do that to us. And with the progression of Asuna's corruption, I don't think Inoda will need to use aphrodisiac candles to get her in the mood for sex. I believe that the perfect ending to Part 2, assuming there's gonna be a Part 3 after this, is with Asuna consenting to IRL condomless sex and a short aftermath of her not caring about the guilt of cheating anymore. Inoda has nearly broken her morals and reasoning when it comes to sex in FOG. In the next update, he'll start breaking her down IRL.
Update 0.90 would be when Asuna finally consents to the IRL condomless sex and they have sex that same update.
Then in the next update, she's thinking about how there's no reason to deny the feelings she has, the pleasure she gains from having sex with Inoda, and rids herself of any guilt she's had up to this point. She'll talk to Inoda about breaking up with Kirito but Inoda wants her to continue "dating" Kirito, by never really giving him the time of day and prioritizing Inoda over him most of the time.
Then the last update, Kirito, Inoda, and Asuna go into FOG, and they do a mission together. While Kirito is fighting the enemies, Asuna and Inoda are hooking up during the fights, and Asuna is trying to drag these fights out as long as possible by buffing the enemies and debuffing Kirito. After the mission, they take a break and both Inoda and Asuna each make an excuse to leave Kirito to do some more degenerate acts with each other. And that's when we'll see what they're doing behind Kirito's back: the scene that plays on the main menu of the game. Part 3 will mostly be a showcasing of Asuna's descent into further and further debauchery, participating in sexual acts that'll increasingly get more depraved as we go through the game.
Assuming there isn't gonna be a Part 3, then we'll get Asuna's consent to condomless IRL sex most likely at the end of the year. It'll be Fujino's Christmas present to all of us. Anyway, those are my 2 cents, thank you for coming to my TED Talk.
