I cannot thank my editor DrBisensual enough. Without her encouragement I would not be submitting this work. I made a lot of mistakes and I may have run her teacher's pen out of red ink.
I do not condone the building or use of devices described in this story. Use of any electricity on a person can cause mental or physical problems. The hazards described are true every other aspect is pure imagination. Everyone in this story is at least 20 years old.

In most stories it is best and easiest to begin at the beginning. After a divorce, I had taken a job supervising a shift of cold call sales people. I was the old man of the group in my late 50's, including me the average age was about 24 of the twenty people on my shift in the office fourteen were female and the other six where trying to get into the panties of the fourteen. My job was primarily to keep them in their own cubicle and keep the phones in working order.
One day, I was replacing a handset on a phone that was having problems. As I worked in the small space of Lysa's cube, I inadvertently brushed against her arm. She jumped and made a strangled sound of pain. Looking at her, I noted a small amount of blood on the long sleeve of her blouse. She refused to show me the arm. After a bit of discussion and repairing the phone, she asked me to meet her at a restaurant after work, so she could explain.
Her choice of location was interesting. It was Italian with large deep high backed booths lining a wide hallway of a room. Wine bottles covered in wax hold candles, providing dim light in each booth. After ordering our meal, I ask to see the arm, she put a finger to her lips to quiet me. The waitress stepped up and places some bread and our salad. I wait and as soon as we are alone Lysa begs
"No, no, no." She quietly pleaded. "It is not like that." She then explained as she rolled up her sleeve showing burns on her right arm.
"Cigarette burns?"
"No, electrical burns." She opens her purse and places a small black box with wires connecting it to what looks like a kid's headband. Picking up the box I see that it is an old flash attachment for a camera, and in the 'headband' are foil contacts.
I leaned back in my seat, "Wow. Why?" her answer was long and detailed, I could see the fear and honesty in her face. It boiled down to the fact that she has an unusual fetish. She only has satisfying orgasms when she gets shocked just as the orgasm hits. The problem was the device she chose. When you turn on an old flash unit it makes a high pitch noise as it builds a charge. The "charge" is in a capacitor that releases a large current at high voltage. This girl was risking death every time she connected the flash unit to her body. She explained that she was having problems the batteries where to strong. However, if she used weaker batteries the unit did not charge at all. Maybe I can explain the problem to you. She had removed the flash tube and ran the wires to her headband. But the circuit was designed to only fire the electrical charge when there was enough current and voltage to operate the Xenon flash bulb. There was no way to control the amount of current sent to the skin. The only reason it did not kill her was that both contacts were on the same arm and no current was passing through the heart.
"Ok, I can help, but first you need to take better care of your burns and that one is infected." She stopped me by putting a hand on my arm and a finger to lip as the waitress delivered our meals.
As we dined Lysa vowed to get some antibiotic salve and visit her doctor. Then asked, "What else do have in mind to help me?"
My reply surprised her, "We can make a safer shocker. Do you know of an electronics hobby store?"
"Vonak's?" She asked.
"They will do, go in and ask for a small transformer like in a hand held radio, Six on-off-on single pole switches, one momentary switch (push=on release=off), six female connectors, six leads with male connector to alligator clip at least a yard long, a 9v battery connector and battery and a plastic box to hold it all." She dug a pad and pen out of her purse and we made sure the list was on paper.
"So, what does all this stuff do?" She asked. I answered her question with a question, "What do you know about electricity?"
"With some wire, a bulb, batteries and tape, I can make a flashlight that only turns off when the batteries go dead or I take it apart."
"Do you understand why your device burned you?" Looking me in the eye she answered, "Not a clue."
"Would it surprise you if I said, electricity is loose electrons being pushed or pulled from atom to atom?"
"No. I believe you, but what is it pushed or pulled?"
"Pulled, but it is easier to explain as pushed. Honestly, at the speed of the electron it does not make much difference." I explained.
"Why do I care how this stuff works?" Leaning forward looking her in the eye, I said, "because not knowing it could kill you. What do you think is more dangerous Amps or Volts?"
"Volts!" She smiled knowingly.
"Nope. However it is a bit of a trick question because point zero one amps or more will kill if it passes through the heart of head. If it does not pass through those vital parts it just burns. The information that will interest you is point zero zero one Amps will get your attention in a hurry."
She nodded knowingly, "you're talking of pain when you say attention."
"Yep"
"So what is the difference between Amps and Volts?"
Laughing I gave the garden hose explanation, "Electricity is like the water coming out of a hose. Volts is the pressure pushing the water through. Amps is how much water is coming out or how fast the water can fill a bucket. If the hose is small even at high pressure your bucket will fill slowly, but if you trade for a fire hose even at low pressure your bucket will fill fast. The size of the hose would be called resistance or Olms. I may have over simplified, not that you need it, but the math works out Amps = volts times olms"
"My guess is your toy is pushing close to a full amp at about two thousand volts and last about a quarter of a second. That parts list I gave you will make a device capable of between fifteen thousand and thirty thousand volts that lasts a nano second and never makes more than point zero zero five amps."
"So it hits me hard but will not burn or kill me?"
"Yep."
"Where did you learn this stuff?"
"My high school offered electronics classes. When some kids where charging capacitors to shock each other the teacher got a bit mad. He made us read how many amps our capacitors stored and showed us how dangerous that was the capacitors that gave the best shocks where close to 1 amp. Then, he taught us how to build a box that when you turn it over shocks the living shit out of you but never harms you. That is what we are making but modified for your fetish."
We finished our meal with little more discussion of electronics. I did convince her to see a doctor about the burns. I told her to make sure the doctor understood the device would be destroyed. A few days went buy and she requested a half day off on Friday to see a doctor. She met me at the door after work the day of the appointment.
"Doc was pissed." I replied, "I would have bet he would be."
"He wants to see me in two weeks for a follow up."
