The act of humiliating a girl by ejaculating on her face and having her sit with it on her face until the sexual component has left, and the situation turns to humiliation. As she sits there it's imperative she cannot wipe it off. During this time you ask her questions about how she feels and whats going through her head. By this time you will see the mental breakdown begin.
I totally want to deface her face. I think she wouldnt be as stuck up if she had a load or two on her face and i had her ponder why she is a whore.
