Author's Note: Some of the ideas in this story came from a blog post about Deviant Designs and I modified some of those ideas for Susan.

"Welcome back, Miss Mitchell, did you have a good Winter break?" West Valley Headmaster Stephen Krutz said to his prized student as she arrived in his office on Monday morning for the first day of her last semester. Susan, naked as usual, thought about the video of her fellow senior cheerleaders lounging topless on the deck of a fancy yacht with drinks in their hands and thought about how 'not good' her break had been by comparison. She had spent most of it being tortured in a series of sadistic contests with another woman. She stared for a moment at the older man but said nothing and took her normal position kneeling next to the headmaster's desk. The young woman had a lot of time since returning to the school over the weekend to think about her plans for the rest of the year. She had learned last week that the headmaster was trying to turn her into a submissive in order to get his hands on millions of dollars her mother has stolen from a drug cartel. Susan still wasn't sure of next move, but she had decided to play along while she worked on a plan.
"I've had some of the geek guys and gals working on some new ideas for this week. I think you will enjoy them," he said. Susan seriously doubted she would enjoy anything this man had to offer. Krutz got out of his chair and the former cheerleader knew that was her cue to rise and follow him. The pair walked out of his office, the naked girl a few steps behind the older man, and proceeded down the hallway towards one of the industrial arts classrooms. Jennifer, the blonde mistress who had explained Krutz' plot had encouraged Susan she needed to convince Krutz his plan was succeeding. Susan wasn't sure this was the right move but hadn't come up with a great alternative yet, so the girl decided she would feign obedience for the time being.
A small group of students was already in the room when Susan and Krutz entered. "Joshua, what do we have first for today?" the headmaster said. The boy approached Susan with a pair of small weights with clips on them. "Please spread your legs, Susan," Joshua said. The girl looked at him with a sneer, but knew she had little choice but to obey. She spread her legs wide and the boy bent down and clamped one of the weights on each of her pussy lips. The clips hurt a little but the weights were not that heavy. The boy attached some thin wires to the weights and Susan knew what that meant. She had experienced electrical shocks to her genitals before and was not looking forward to more of that.
"I need to you to come over to this table," he said. Susan followed the boy. He directed her to stand against the short end of the table and asked her to lean over it so her stomach and breasts were resting on the table. The boy spread each of the girl's legs so her toes were touching the table legs, but surprisingly did not bind them to the table itself. Joshua pulled Susan's hands out in front of her so her head touched the table and her palms were face down on the table top.
"Please look straight ahead," he said to her. She did as she was told and saw a camera now pointing right at her. She put her head down to hide her face and felt a sharp electrical shock against her labia. The shock hurt but was not extremely painful. She lifted herself off the table and the shocks worsened. "You really need to stand still, Susan," the boy said. "This is a motion capturing camera and it is connected to pressure pads on the table legs. As long as you keep your toes against the table legs, your hands on the table, and face the camera, you won't be shocked. But any movement will cause you pain."
