Yes, yes, a thousand times yes!!! I have from time to time run across perfectly legal girls, 18 years or older, who represented themselves as virgins on rape fantasy sites such as this and thought, "Oh my, what a nice win win opportunity!" It makes perfect sense that a girl or boy for that matter who is a virgin, and perhaps not having a clear path to having their first sexual experience might fantasize about hooking up through forced sex.
I know people have various modes of fantasy. Some fantasize about being a creature from another planet and fucking a whole village of women. Some fantasize about being raped and beat up and there's all kinds of crazy stuff out there. Me, weirdly enough, my fantasies tend to be things that are legal and that I'd actually like to try/experience, if I stumble across a willing partner.
So, because of how I fantasize, I don't just fantasize about some imaginary virgin. I would have to actually run into or across an actual virgin, legal age of course, on a site like RC, preferably someone who fantasizes about initiating her sex life through forced sex and that would be a wonderful fantasy come true for both of us. Of course I would want it to be very good for her as her first experience and leave her with a good taste in her mouth!
