My girlfriend of 3 months and I have great and regular sex, but she has been bringing up these rape erotica stories she reads when I'm away, i read them and they are super intense, like legit real rape stories with guns and shit, and she said she gets turned on by them.

I have tried being more rough and dominant than I already was, incorporating the sex god method, i do choking, rough grabbing, throwing her around the bed like a ragdoll, commanding her to do stuff ect. and she is into it and wants to fuck more than I do now, but I feel that she wants to be truly abused and used for her holes in a very rough, no fucks given full on rape way because I have never been able to make her cum from just my dick, only gspot orgasms with my fingers. I feel that some rape play would push that over the edge for her, some wierd part of me wants to be the first guy to make her cum with just dick (if her claim of never being able to cum from dick alone is true)

She said she has never been raped/sexually abused, anyone here have experience bringing this into a relationship? i don't know how to work up to that point. Or do these stories just turn her on because of the dominance aspect?

And a side note I have vetted this chick for 1.5 years now and I trust her and am confident she is not crazy.
