I am a victim of sexual assault. I have the fantasies though, but i guess in my head i dont see it as "rape". (if that makes sense)
Let me explain a bit more. When rape happens it is uncontrolled and it is horrible to go through or even think about going through. whether or not it happens by someone you know ro a stranger, it is not wanted and not asked for in any way shape or form.
But the fantasy for me would start off as not knowing when it was going to happen, BUT the main difference is, if it happened and i wasnt in a safe place, the safeword would stop it immediately. And I would trust my Master 100% to stop it there and then.

I guess you could put it down to wanting to pass 99% of control over to my Master, but my 1% of control, the safeword, is the thing that would stop the rape play scene in a heartbeat.
