Despite popular belief, all women enjoy rape. This is because all women are whores. However this doesn't mean that they're all obvious whores. Besides your typical school skank and office slut, whom are clearly whores, there are those known as Secret Sluts.
Secret Sluts are the rarer form, but ultimately a more fun victim to rape. Examples of these are children and virgins. If you can't get a child or don't want to risk it, then find an innocent small-bodied teenager. She will work just as well. Act like you are her friend at first or that you are interested in her, and she should succumb to you right away. These girls are dumb as hell. If you're lucky enough to have gotten a virgin then she should be extra tight. Not only will you cum really fast and very strongly, but there is no better feeling in the world than watching some girl cry in pain as you're popping her cherry. Pull her hair, spank her, even cum in her mouth for added effect. Have her tell you that she likes it, and if she doesn't then threaten to pound her even harder. These girls will just grow up to become sluts anyway, so they might as well get accustomed to the feeling. Make sure you cuddle these girls afterwords though, just to make them feel a little less "raped". Just kidding, tell them to go make you lunch. After she brings you lunch, pop her in the anus for good measure.
