if she is already toying with the guys "real" cock (as shown in the infirmary scene) I do not see why she would not have virtual sex. there are like 5 scenes where she constantly says no sex while playing with his dick. and that is also considering that mutual masturbation does happen as a peeping event in the virtual world. you can clearly add the scenes I mentioned during that time period where a logical argument of (virtual sex is not real sex) would lead to actual sex instead of the contrived notion of thunder storm+ kirito's uncharged phone+ him sleeping.
Please do not engage in a straw-man by saying I do not understand the process of corruption. the truth is that you do not even know the things I know or not know about.
i really cant comprehend why you are thinking it would a logical argument for someone like asuna that virtual sex would be ok, because its just virtual. she is always doing all those things with inoda with the mindset that she is just helping him with becoming a better person or so he can move on from her.
doing handjobs is to relieve his hard ones, while the masturbation was accepted by her with the reasoning: "he wants to repay" her. there is no logical step up to having sex, even if its only virtual.
i dont know if you already played p2,
but at the end of the current update, her believes and mind gets changed to: "its only virtual, not the real life" so its highly possible that asuna didnt believe that virtual is just virtual. at least not intimate stuff.
sorry for my phrasing. you are right i dont know what you know or dont know, but I just couldnt understand your way of reasoning...
