I am sitting on the chair cradling the receiver to my ear as he tells me what he is going to do. 'You will wear a white blouse and a short black skirt. Black stockings. Suspenders. Black lace bra. I will tie your hands together in front of you and lead you upstairs to the bedroom. I will run a rope from your hands down through the futon so when I pull on it you will be forced to bend over.'
