You know, the forced oral sex may be yet another form of humiliation and dominance. From a perp perspective, I think one act is "taking something" and the other is "forcing humiliation." In a closed car which was locked, I think I would be more scared to fight back as in he may be going to drive me a way to my death. In an open house with friends sleeping in other rooms, I would doubt that you could force that same act without noise or resistance from Bri. I think the sexual evidence in Bri's case is critical, if she was not raped but DNA from semen was found, this guy maybe cannot get an erection in the rape scenario- which could be key? Is there any possibility there could be another player here? Some sort of sick rapist tag team?
At any rate, for the 10th time, he really scares me.
