Wouldn't that be something, like the porn animated version of real housewives.
Now in reality Fujino did made the entire plot even more predictable, Suguha will be the plot device moving things foward the halucinations also are cheap excuse for Asuna escapedes.
One thing that is overdue to happen is Asuna getting some heat for her actions, for that now you have Suguha.
The perks list said something about phisical needs as the main excuse for IRL sex, for that something will prevent Asuna having sex in FOG and the sex with Kirito IRL never was fufilling for her anyway, and now Suguha will be more around Kirito just to block/antagonize Asuna making her crave for Inoda's dick.
And since Suguha will not talk about it with Kirito just yet, when she learn about the content of his halucinations Inoda/Asuna she will make her move seeding doubts in Kirito's mind.
