You see? The problem starts right there. Asuna wants her boyfriend (or spouse or whatever) only fucks her, but Inoda surely will fuck every hole he finds. And this won't work, but since Asuna is just a slut, she probably will want to keep Kirito as her boyfriend and won't want Kirito to cheat her, but since she can't be satisfied sex with Kirito she will continue to fuck with her sex friend Inoda and the excuse will be there everytime. And of course she won't fuck with Kirito, cuz Kirito's dick is "small" and can't reach "the deeps her pussy".
Also Kirito is a hardworker, not a fatass and was her boyfriend for a long time. With keeping this status quo she won't be blamed by society as well. Cuz let's be real, her father won't want a fatass who can't do anything other than humping and this won't do, cuz Asuna needs big dick.
Well, the best solution for her actually is finding a new raper, which is not fatass and somewhat useful or maybe finding a rich guy with a big dick? But the problem is that other people won't be stupid like Inoda and rape her, so she will probably will just stuck with Inoda
