We were about to move onto the next phase of punishment when my secretary asked to be excused to go to the restroom. I was about to let her go when I had a wicked idea. I knelt down next to Cindy, and asked her whether she would like to help us out. She looked at me uncomprehendingly, tears still staining her face. So, I spelled it out for her. My secretary needed to relieve herself, and here was a willing sex slave to save her a trip. Cindy went pale and shook her head, saying that nothing we could do would ever get her to consent. I smiled, grabbed her hands and tied them behind her back. I hefted her onto my desk, and tied her legs apart, attaching the ropes to the desk legs. I looked in my drawer and found what I wanted: an electric wire with two ends split apart and layed bare at one end, and an electric plug in the other. I pushed the plug into a wall socket, and touched the two wires to one of Cindy's tits. She jumped convulsively and screamed. I smiled and told her to stop me whenever she agreed to what we wanted. Over and over, I applied the ends of the wire to her tits, leaving little marks on her nipples and all over her breasts. Finally, I moved down to her cunt. I applied the wires to her clit, holding them there for a couple of seconds. She screamed shrilly and strained against her bonds. I ran the ends of the wires up and down her swelling cunt lips. I could see little sparks burning her tender flesh. Her legs were extremely tense; her whole body was covered with sweat. After thoroughly shocking her cunt, I finally moving to her asshole. I held the wire ends to her asshole for a while. Her screams got loud and panicky. Getting tired of waiting, I finally shoved one wire into her asshole, and one into her cunt, leaving it there. Her body went rigid as the current flowed through her. Her teeth clenched. I asked her again whether she would do what we wanted. Finally, she shook her head yes.
