Financial Blackmail and Torture

In this fictional story, a man with mild BDSM submissive desires has his bank account hacked and he is blackmailed by a sadistic dominant woman who requires him to suffer torture much more extreme than he had fantasized about, including several BDSM activities which are among his hard limits. Excerpt: There was none of the warm up or slow ramping of pain as I read about in many BDSM scenes and the pain was intense from the very first blow. The flexible whip on the end of the shaft felt like it was going a million miles an hour when it cracked against my skin and the sound of my own flesh being assaulted by it was sickening. I could not concentrate on these things, though, as mostly all I could hear was the sounds of my own yelling and screaming, with several breaks during which I whimpered uncontrollably and my body shivered from fear and pain.
