I did sort of the reverse of this...I put out the do not disturb sign on my door, but with a key taped to the back of the sign. The agreement was that she would sneak in sometime between midnight and 6am, get naked, slip under the covers and suck my cock to wake me up - sort of a very exciting wake up call
Irl, I had a gf who had the whole rape fantasy. Tearing off clothes, spanking her, hair pulling slapping, calling her names, the whole bit. So after lots of discussion, we agreed to a scenario. Safe word and all. I'd sit next to her in the bar, hit on her, but she would turn me down, be a little condescending. She would pay for her drinks, I'd quickly pay for mine, then follow her into the elevator. I'd let her select the floor first, then I'd comment that I was on the same floor. When she got to her room, I'd pass, but only a few steps. Before she could close the door, I'd stick a foot in. After that, it was hand over the mouth, tearing off her clothes, calling her names (we agreed beforehand what what acceptable and what was not: bitch, slut, whore and cunt were fine, but "stupid bitch" was not). Light slaps to the face were fine, hard slaps were not, and punching was certainly out (which was good, because I couldn't do that). I let her tell the fantasy in as much detail as she cared to, only asking for clarifications as necessary. Biting was one of her enormous turn ons, so I obliged. Greek wasn't for her, so I definitely didn't go there (but I did threaten to do that unless she did as I demanded, which she later said was fantastic). As you can tell, communication is the key here. That, and a willing partner to live the fantasy.
Never in 1,000 years would I ever remotely think of doing this kind of thing unless it was explicitly desired. But I have to tell you, it was fucking hot.
