I mean, Fujino could have changed it by now, but no, actually, that's not how it works: There is an "option" to "disable" the 'protection' (Called Ethics Code in Canon SAO), but it's literally a toggle you turn on and off, not something you allow someone else with permission like a wifi password XP For NTR Purposes, though, in FOG EITHER player of a husband/wife couple could deactivate the other's ethics code (Which is not only incredibly stupid but also a massive violation that if FOG didn't work magically with +18 content to the level of literal whoring on the streets being allowed yet not being immediately shut by the government for violating a million laws it would never make sense to exist in any public VR game XP). Kirito simply deactivated Asuna's for Inoda when he asked, like an idiot, but Asuna 100% could just turn it back on herself afterward. Again, it's not a wifi password, is literally an on/off switch, and Asuna should immediately realize it was off next time she did it with Kirito if not earlier XD (The fact minor insertions and the like are allowed is stupid and just for Fujino's NTR-verse, though, canon-wise you can't even remove someone's underwear, and even touching there would already be giving you a massive warning that the other player would immediately notice and press to 'report' you and sent you to virtual jail/get reported to the admins...none of which exists in any corner of Fujino's NTR-verse VR world for obvious reasons
