I see she's learning to be more observant of the suggestive nature of things, by whatever time this takes place. I mean, she's getting more gutter-minded with time. For reference, to me, mind-in-the-gutter is different from just straight up sex-on-the-brain, because, as much as Anna has wanted more skinship, she's frequently been shown to have a curious level of 'innocence' with things related to sex, such as double-entendres or innuendos that Kyo picks up on but she seems oblivious about, particularly certain extra chapters like the one where they watched a horror flick and she kept repeating 'it's coming', and it seemed really obvious she had no idea what she was doing to Kyo by repeating that.
Yes, she seems eager for it, thirsty for it even, but that doesn't mean she knows and can realize all the implications that lead to it. But she is learning, and will start leveraging that more intentionally, I bet.
