Not that our opinions here count or reach Fujino, but I'd also like Asuna to be mostly for Inoda's use. It lets her maintain her public perception of being pure and noble, and maintain the outward appearance of her ironclad relationship with Kirito... while being an absolute slut in secret for Inoda. Once a girl starts being a public fucktoy for everybody, the interplay of secrets, identities and perception is diminished; a high class women becomes publically worthless, instead of being both a private whore and a public angel which makes the private persona more hot. And if you think about it, it doesn't make much sense. Inoda is not a playboy, he can't easily get another woman. He wants to monopolize and steal Asuna for himself.
I could see the guy corrupting Suguha sharing her, though. He's a playboy, he can get other women. Suguha is nothing but a hole to him. He'll get bored, look for other, new targets and either start loaning Suguha out or just ditch her and move on.
