But for the sake of fantasy, I would go for full Stockholm syndrome. You would live in a little isolated perverted paradice, taught very early how to pleasure yourself and your master. I would spent nights with you by masturbating your little slit and talking about how I will kill you on your sixteenth birthday. If you will be a good girl, we can do it earlier and you will even get one last orgasm. What will it be? Chop off your head? Throw you into a wood chipper? Throw you to the hungry dogs?
