Asuna will become such a slut that she will no longer need the hiding places and will force Kirito to watch her while she fucks Inoda
This could happen if Kirito's level of perversion is at its maximum
p.s this is my thought of what happens next (it could also be an ending), so, since Asuna will become such a slut that she will leave Kirito and fuck Inoda, but since the small dick theory with Kirito doesn't work anymore and so while Asuna fucks Inoda, Kirito takes out his big dick, Asuna is shocked by Kirito's performance asking questions like how? Since when? Will you give it to me? and Kirito replies: No, this dick belongs to Suguha, have fun with your stinky fatso
