Omg seeing the nervous system send female Hormones information into the brain is such a good concept for mind altering TF. Lets just say that's my interpretation
Would love it if the reason she's like this is her hormones and adrenaline mixing up, maybe she gets an uncontrollable feeling the first time around to play with herself or maybe she gets aroused from sneaking around the ship while naked with the risk of getting caught exciting her.
