You want to see hand holding and cheek kissing in a NTR game? EEEEWWWW!!!!
But seriously what kind of girl do you want Suguha to be? A pure girl or a rapist girl? She already had plenty of access to Kirito's unconscious body so the hand holding and cheek kissing seems so tame and out of character for her now after all the stuff she has done to him. Also I am sure if she wanted photos she has already plenty of photos and videos for her to use. A lover's selfie seems more like a pure girl move and would only have meaning if Kirito was awake.
Suguha clearly enjoys more than simply taking advantage of Kirito defenseless body, she has been going to his house to cook, clean, and do chores. She also has clearly enjoyed going around town shopping, drinking coffee, and watching a movie with the world most unaware cuck.
I don't think that it's a wild interpretation of her character that she wants to be the closest thing to a lover for Kirito as she could possibly can.
Sure, she is a rapist much like Inoda is, but she has shown care and love for her victim unlike him. With the pig, I can't imagine him being happy with something like hand holding as long as it doesn't help relieve his constant sexual desire. Suguha seems different, since she is not always thinking with her vagina.
She can desire a tender and romantic moment with Kirito, while simultaneously plotting to roofie his drink and suck him dry until his sack is drier than an old raisin.
The whole cheek kiss and hand holding was partially an hyperbolic joke, trying to explain how anything would have been better than nothing. That being said, I would think that wanting those "pure" moments are totally in-character for her.
