As I struggled in my binds can see Diddo is in pain and has a scared look in her eyes. Not sure what is wrong with me despite all the pain my cock still is about half hard. What seemed like a couple hours later the others came back to the dungeon. Mistress Janice tells Diddo to get up and start sucking some more. With my cock half hard it didn't take long to get shocked again. After three more times and my cock now limp mistress Nora had the servants free me from the chains where I collapse next to Diddo. Mistress Nora kicks me in the ribs and take some smelling salts to wake me up. Once up mistress tells everyone "i want to make sure she is fully trained. Now Rose on your hands and knees." Mistess then has Subs with fat strap on get in behind me and begin to fuck me from behind. I could feel my cock start to grow but tried to think of other things. I was doing good not to become fully erect until she had Diddo present her cock to my face and forced me to suck. As I was sucking Diddo's cock I could feel my cock start to grow some more and didnt become fully hard until Subs started thrusting harder and Diddo came deep in mouth. Diddo and I dropped as we were getting shocked. I did manage to not spill any cum. When stopped crying from the shock mistress forced me back on my knees. Mistress Janice felt Diddo in her weekend condition could take any more shocks so she turned the switch off. I got shocked two more times before mistress Janice said we both had enough for today. Mistress Nora said "fine but before we can rent them out Rose has to learn to want to give pleasure without any in return. " Diddo and I were led back to our rooms to rest for the night so we can train in the morning.
