Slave fantasy of mine. I'll just illustrate the setup because the entire thing is just way too long.
"Toy". " yes master?" "I have decided that I am going to hurt you very badly today. Not because of anything you have done but because it will please me greatly." "Yes master, whatever you like." "We will play a little game you and I. Today I will only use 2 instruments on you and you will get to partially decide when I use one of them. The first is a 20" piece of 16 gauge electrical wire attached to a wooden dowl. I will use this to whip you until you decide I can use the second tool. The second tool is a soldering iron. Here are the rules. You must endure the whipping for 1 hour minimum before selecting the soldering iron. The soldering iron will be inserted into your pussy for no more than 10 seconds and no less than 2 seconds. You will be able to lower the time the soldering iron is in your pussy by enduring an additional 15 minutes of whipping with the wire for every second taken off. To get it all the way down to 2 seconds you must endure 3 hours of whipping with the wire and no place on your body will be safe from the wire save for your pretty face. I prefer that intact. You will be tied standing and spread eagle. If you pass out at any time during thi's ordeal the timer will be stopped until you awaken and we resume. I will not ask you if you are ready because it does not matter to me. Now, strip."
