I am literally obsessed with secretly watching my girlfriends best friend (since childhood) have sex with a black man. I do not want to join in but just watch. Her name is Lisa. To describe her, she has blond hair and big boobs with an hour glass figure. In a way, with the contrast in skin colour, I sort of think that this is I deal for a black man. Also, she has a black vibrator so I believe (well, I once heard that). I know that there are several similar fantasies to this but I feel confused as to why I have it and why it is so dominant in my sexual thoughts. My girlfriend is absolutely stunning and a fox in bed with hardly any inhibitions. So why do I have this fantasy?
