come on, let's face it, ntr is dying, seeing Asuna do things without any worries is like playing a normal porn game
Kirito doesn't know anything about what's going on or maybe he does but he wants to see how far Asuna wants to go so he can catch her.
Asuna: Kirito, do you know that I betrayed you?
Kirito: I know
Asuna: And why didn't you prevent this from happening?
Kirito: So you put all this act together to see my reaction but since I didn't lift a finger because there's a guy named Fujino who took away my eyes, ears and brain, everyone calls me stupid just because I have to play the role Fujino assigned me, you kept fucking that bastard hoping that I react but you were so used to it that you ended up pushing me away, and you want to know the truth? I betrayed you too, and yes, while you were doing the splits on that fat guy's dick, I was having so much fun with Suguha and not only her

I may be a cuckold but at least a happy cuckold, bye bye Slutsuna
*Kirito goes to Suguha to have fun like there's no tomorrow*
