Wait... Are you seriously arguing that the same Asuka even you agree is interested in her mom as much as to masturbate to her on her bed would not have a sexual reaction to this kind of touching by the object of her desires?
First of all, at this point she doesn't understand what she feels for her mother yet (she didn't masturbate to her in her mind, she was just attracted by the smell), secondly, even if she had one, it would be superseded by unrelenting shame, fear and instinct to escape. She was downright afraid by the end of the whole thing. Because she doesn't know she is attracted to her mom, in her mind only the fact that she did something really shameful and her parent might find out is relevant.
She has never shown an extreme reaction like that again even when she knew her feelings, so that just seems implausible at best.
