I could comment a novel here, I've had rape fantasy be a consistent issue with most newer women that I meet, like I have the chick's from my past that I bang, they are straight forward but it's something that I have dealt with a lot, I even tied a woman up the first time i met her, upon request and this led to my rule no bondage on first meet up.
I call it an issue, because engaging in risqué sex and rape fantasy kind of go hand in hand, like public sex will always have an undertone element of rape to it, the taboo.
I would imagine this woman, based on my own experiences, also regularly does things that are taboo so she can get a high off it, like shop lifting or maybe she's got a bf at home and is with you, if she is one of those seek the high types, run away and don't look back, they are decent to keep around until their high is picking at you, oh nvm FWB only is probably fine
