Just a theory, hopefully the ingredients gathered during the trip earlier factor into what the next scene is. Something along the lines of an aphrodisiac for Asuna and something drowsy for Kirito. That way Kirito passes out first and Asuna is aware he can’t help with her issue (being horny) and for the first time actively seeks out Inoda’s help. Liz probably takes Kirito to his own tent as well and discovers how lacking he is and sees through the tent how wild/big Inoda is and that’s where her downfall starts too.
I’m personally most curious though what the first IRL encounter for the two of them is going to be like, since they’ve done so much in game, doing it in person is going to be a big payoff. Considering based on perks list released some time ago sex alone isn’t end game for Inoda, we’re in for some roleplay (cosplay too), anal, toys, voyeur (public), and even multiple people. Wonder where this part 2 ends? When they confirm the relationship extend to IRL as well most likely?
