suck her tit like a cock. Bounce or bobb your head on her tit just like you would if you were sucking a cock. Do this at least once a week. Third week, start sucking her tit then tell her that you are fantasizing. Hoping she says what are you fantasizing about. If not, suck her tit like a cock then just say -- I am fantasizing that I am sucking your tit like a cock.
