I mean it more that at that point Suguha seemed to have snapped enough to have just straight-up raped Kirito without remorse and tried to get herself pregnant with his kids, then suddenly adds like an afterthought in a small scene that if you don't look in the rec. room you would completely miss that she's actually just using her ass because she wants their first 'normal sex' to be 'special', it just felt weirdly forced tbh XP
Well, when I was playing that part of the game myself my original thoughts regarding what Suguha was doing were a bit different. I at the very least didn't think that she would have gone and straight-up had sex with Kirito when she initially put the hidden Camara in his room, so I was surprised when we saw the first scene in the recollection room.
At most I was expecting her to give her that classic incestual Hawk Tuah, or the Alabama handshake that only a sort of sister could give.
I didn't love the fact that Fujino made it look like something was happening, only to twist it later with the "it was only rubbing" revelation, but it made sense for me from the perspective of the narrative, as it was too early for Suguha to do something so forward.
And it terms of writing and characterization it depends, the whole excuse of "I want Kirito to be awake for our first time" is not yet something that I wholly buy, but I might end up coming around depending on how Fujino develops Suguha's character.
The way I would personally like her arc to go is that currently her reasoning is just an excuse, and that Suguha knows that what she is doing is morally wrong so she doesn't want to fully rape the person she loves. (Unlike a certain piggy who wouldn't hesitate on raping any hole he comes across if he thought he could get away with it like a dog in heat.)
Then, when she is pushed for whatever plot reason in the future, having her acknowledge the wrongness of her actions but committing to actually having her way with Kirito would be my ideal progression for her.
Of course, most likely Fujino will not go down this path, since if Suguha and Kirito actually go anywhere in the future I can see him simply having Kirito drugged/mentally altered and Suguha taking that as a green light to stick little Kirito on her sisterly oven anytime she wants.
It's so hard to find good Suguha art out there, I can only hope that some greedy studio decides to remake the original SAO anime with the progressive Light Novels/manga, just for new artists to start making more lewds of the series, and that Sugu ends up attracting some talented degenerate.
Either that; or I need to wait until AI stops making mid pieces of bland content in a decade or so.
