I love a good Murder, Mystery movie and watch many of them on cable television. The one central plot in most all of them is the person is blackmailed and then is anguished as they squirm doing what the blackmailer makes them do in the movie. This last week I started plugging a spanking with a paddle or strap as an enhancement into the original plot in my mind and it worked beautifully for me.
Imagine someone being physically punished by one blackmailer who got rid of them and found their new blackmailer also spanked them! There certainly would be an emotion uproar. I have finished Jeans Down For Heidi's Hiney where I used that plot line. If you are interested it is under my author name, Cherry Red.
I am always interested in good' Blackmail Spankings' stories, so if you can recommend a good one, I would love to read it. |
