While the nerds amused themselves learning all they could about mom's tastes in pain, their leader worked furiously on a list of potential tortures that they might try on their guest of honor. Once the list was fleshed out, it became apparent that it would be more reasonable to move mom back to the wooden chair. However he did come up with a few that would work ideally in the position that their captive was now occupying. He figured that it would take at least another couple of hours until the ties would provide the full effect on their guest's tits.

Elf called a pair of his nerd crew over and instructed them to retrieve the fireworks that they hadn't used during last summer's celebration of our nation's independence. This would be a good way to pass the time and also allow them to learn even more about mom's preferences and limits for pain. To Elf there was nothing more satisfying than discovering a way to perform parallel processing.

While they were searching, he told another pair to bring out the rheostat controlled generator. This would provide lots of information on mom's ability to take pain and how much was too much. Not only that, he was pretty well convinced that what it took to make her beg for mercy in one spot on her body was not the same as another. Except for her big tits which were getting bigger by the minute and headed toward the color black, the rest of her naked body was open for testing.

They would all be in nerd heaven as they got the opportunity to take a wealth of data that would require computer analysis to develop the proper algorithm for electrically torturing this woman. He was already thinking ahead to other opportunities that would allow him to test other female specimens of different ages and body weight. Elf was sure that given enough specimens and collecting the right kind of data he would be able to come up with a practical algorithm that would allow any male to pick the correct levels of power for any female despite her age or differences in body weight. He began to wonder if he could convince his mother and perhaps his cousin to join this test group. That would certainly make for a most enjoyable time around his place and keep his crew gainfully employed doing something that would benefit mankind, which in his warped world only included members of the male race of humans.

The nerds wheeled the generator close to the frame on which mom was roped. It took a few minutes to get the leads untangled and the alligator clips properly attached to them. Then the fun began. Special conducting paste was smeared over the insides of her spread thighs, and then the leads were clipped to the pinched skin and checked to make sure they were digging in to the correct depth before the nerds started putting the juice through her. To ascertain the dividing point between pleasure and pain, one nerd was assigned to check her cunt for moisture. He inserted a mini-hygrometer into her pussy that measured the relative humidity within. The jucier the cunt, the higher the reading. With all systems functioning and every nerd in place, the experiment started in earnest. Over the next hour or so the wattmeter at the house spun at a fairly rapid rate as they passed electricity through various portions of her anatomy, lighting her up like a Christmas tree.

As Elf had predicted, it took differing amounts of electric power to reach the pain threshold for different portions of her anatomy. Her erogenous zones, those places that were the most sexually sensitive, took the most power before pain ovecame the pleasure she was experiencing. Her pussy took the maximum dose of power, nearly smoking before her cunt juices dried up. They checked it out from top to bottom, side to side and then from front to back, which proved to be a very tricky measurement. For this test they inserted a insulated metal probe deep into her fuckbox until the exposed tip contacted her uterus. The other probe was an alligator clip that was attached to her cunt lip. The nerd checking her pussy for moisture swore he heard the juices in her cunt boiling away as the power reached almost to the limit of the rheostat controlling the generator's current output. As for mom, she screamed and begged, all the while her body danced to the electric boogie.

Many of the nerds were very surprised to learn that mom's asshole could take plenty of current before she started to hurt. This proved to be a most messy experiment since once the pain threshold was achieved, mom lost control of her bowels and dumped the contents of her lower intestines onto the floor beneath the frame, causing the experimenters to scatter. This combined with the smell of her cooking flesh were considered to be the major drawbacks of this testing program. Elf made a note to get some kind of exhaust fan in place before they ran the next set of tests and see about situating mom over the floor drain.

Most of the nerds reacted rather badly to the stink of mom's flesh as it sizzled and even popped in some places, such as her big meaty ass which must have had a higher than average fat content. Of even greater interest was the extremely low level of power it took when electricity was passed through mom's brain. Many people consider the brain to be the most erogenous of all the zones, but this experiment seemed to contradict that old wive's tale.

The head nerd was delighted with this peliminary data and vowed that there would be further experiments, hopefully involving other subjects besides mom, who was in a bad way after only an hour or so of testing.The poor pain sponge wasn't used to experiencing the kind of pain that the nerds were dishing out to her. Elf finally decided that she had gone as far as was useful for his first experiment. Unfortunately for mom that meant she now faced a new and even more fiendish type of torture. Worse still her big tits were now the size and color of two old fashioned bowling balls, so swollen that the skin covering them was stretched to near its bursting point. In those places where her tits had been riddled with pins and needles as well as being scalded, the skin was beginning to break open. Her tits were quickly becoming stippled with tiny spots of blood that oozed up from the wounds that had been made in them previously.

While she had been taking enough electricity to light up a small city, the nerds tasked with obtaining the fireworks had been busy extracting the powder from them and mixing it with a matrix that would allow the explosive material to be painted onto mom's skin. Just for the fun of it, Elf decided that mom's erogenous zones would be painted with the powder. Double thick layers were painted around the entrance to her fuckbox, just touching her outer cunt lips and butting up against the hood that protected her fat clit. Her anus and the insides of her thighs received similar coatings, taking care not to actually contact the supersensitive skin of her anal passageway. That would be reserved for some later date when mom was in better shape to take that level of pain. Her stubbled armpits received the thickest coating since Elf was into armpits, that was his thing and so mom's would burn and smoke the most since he was in charge of her torturing.

Mom was so out of it by then, that she didn't realize what was in store for her until the first match was struck and touched to the silver dollar sized clump of black powder covering a section of her inner thighs. At first she spurted a gusher of cunt juice that landed nearly a foot in front of the frame to which she was tied. Then as the stench of her charred flesh spread out from where she writhed, she let out a cry that was part bellow, part shriek and got louder as the powder burned away the outer layer of skin, leaving in its wake something akin to a second degree burn.

Mom was now wide awake and terrified as she finally got the picture. These little fiends could do her some serious and permanent damage, perhaps leaving her unable to enjoy being raped and tortured, a prospect that made her head whirl. She nearly lost her mind when they lit up the entrance to her pussy. She was sure that they had set her cunt on fire and she was going to be scarred for life and unable to feel anything down there again. She shrieked like a banshee and almost ruptured herself trying to escape from the ropes holding her to the frame. She felt the pain surrounding the mouth of her cunt, but was in no condition to realize that her fuckbox was unharmed. Except for a little blistering of her clitoral hood she came away relatively unscathed. The area around her cunt looked like it had been out in the sun way too long, but that was the extent of it.

The same could not be said for her armpits which were roasted to the point that she was left with second degree burns in both. They had set them off one at a time and watched her pussy squirt and then dry up as the flaming powder burned deep into her flesh destroying most of the protective layer of skin. What would remain would be nothing but scar tissue that would always be a source of some nagging pain whenever she had reason to move her arms in a certain way.

There was a brief and very heated discussion held concerning whether to extend the powder coating the region around her anus, with some arguing for it to be run up the cleft between her ass cheeks. Elf was a bit concerned that there was a possibilty that the skin of her flabby ass cheeks just might fuse together when it was ignited, leading to some serious long term damage to a very sensitive region of her body. Cooler heads prevailed and a compromise was struck. A thin coating of powder was run between the bottom of her cunt and the area just next to her sphincter muscle. To the delight of the nerds this little bonfire finally caused mom to pass out from a combination of fear and pain.

There were a number of high-fives exchanged between nerds as they celebrated their complete dominance over their victim. There was no doubt in anybody's mind that mom would give them plenty of respect the next time she was their guest. Some even dared to dream that perhaps they might have the opportunity to introduce mom to the newest members of their nerdette auxillary. Elf had fired up their imaginations and the future now appeared to be limitless to them. There still remained the fun that would be had when mom's huge blackened tits were freed from the ties. They set about reviving the woman for the next portion of her torture session.
