For the record the answer is: ANYWHERE!!!
If I get to spend time with Brandi and fuck her until I cum I really don't care where it goes on her body I am just ecstatic I got to fuck her and blow a load because of her.
But if she told me I could choose my spot to drop my load I'd either choose her fabulous ass cheeks after doggie or her ABS and see her rub my cum into them and make them stand out even more. I would not choose her face........sorta. I would not choose her face the first time we fucked so that when we went at it again ASAP her mouth and face wouldn't have my cum on it and we could go again right away - with the 2nd time my load blasted in her hair so we could make it look like "Something About Mary"
