The first experimental session

The student jerked awake in terror, panicking that she'd overslept or forgotten something she was supposed to do the night before. The sight of the control box on her bedside table did nothing to calm her nerves and it was a few moments before she was able to suppress her fear enough to sit up and check the time. It was still early, but she couldn't go back to sleep, so instead started to prepare for her first testing session. For convenience of both testers and subjects, the sessions would mostly be conducted over video conferencing. The control box could be operated over the internet, as could the traditional shock devices which she would be comparing with her newly implanted electrodes.

She showered, plucked, exfoliated and moisturized, put on her make-up and did her hair, then dressed in a blouse and a wrap skirt that she could quickly remove when necessary. She also put on matching white cotton underwear, although like many girls she often went without for convenience when taking a spanking. She dearly wished it was a spanking she would be getting today, rather than vicious electric shocks to her most sensitive organ.

Feeling a bit queasy, she decided against breakfast, but had a fruit juice and then cleaned her teeth, before preparing her bedroom for the upcoming meeting, ensuring everything was tidy and ready to go. Then, still early, she did some reading for college while she waited, which helped take her mind off her impending fate.

Her laptop pinged bang on eight o'clock and she immediately hammered the reply button, **** not to keep the person on the other end waiting. Forcing a smile on her face, she was surprised to see a young brunette staring back at her from a very white office with a window behind and a bookshelf to her left. She was wearing a white jumper and dark rimmed glasses and Rebecca was instantly jealous of her chest.

"Hello, can you hear me?" The voice was tinny, but quite strident. The ginger girl turned down the volume slightly at the same time as she replied, speaking clearly and as loudly as she could without risking her parents overhearing, since they hadn't left for work yet.

"Yes, I can hear you fine. Can you hear me?"

The other girl also made an adjustment to her system and smiled reassuringly at her test subject.

"Yes, that's perfect. My name's Savindra and you're Rebecca, right?"

"Yes, that's right," she nodded.

"I'm a research student and I'll be conducting the experiments with you for the next few months. Next year, it might be me again or one of my colleagues may take over; I'll be sure to let you know before that happens. First, I have a short questionnaire for you and then we'll get to the testing."

The questionnaire was indeed short, confirming her personal details and asking her to describe her experience with punishments so far. Since she had yet to receive a punishment using the electrodes (other than the single test shock to make sure they were working), that part of the survey was the quickest of the lot.

"Okay," said Savindra, tapping away at her laptop. "Now for the important part. Would you mind slipping off your clothes?" The apprehensive volunteer quickly complied, stripping completely naked, since she assumed (rightly) that if she was supposed to only bare her lower half, she would have been told that.

"Excellent. Do you have the shock device with the serrated clamps we sent you?" Rebecca nodded and picked the object up, holding it in front of the camera. It was very similar to the one her parents used—or had used, before her new implants.

"Good. For this first test, you will receive fifty shocks to your outer labia with this device, followed by ten through your implanted electrodes with the control box. It's very important that you sit still, with your arms by your sides, throughout the testing, to ensure consistent results. Oh, and absolutely no screaming or swearing, do you understand? I said, do you understand, Rebecca?"

For her part, the ginger was stunned. Fifty shocks would be by far the worst she'd ever taken and she never normally had to sit still and stay quiet during a punishment. Shaking herself out of her reverie, she hurried to say she understood, before her hesitation earned her a separate chastisement.

"F-fifty is a lot more than I've ever had before, even for a really serious punishment," she explained, thinking maybe there had been a mistake and the university thought she was used to much harsher sentences, but her tester brushed her concerns aside.

"Don't worry, I know girls who've spent hours on that device. It hurts like billy-oh, but it won't injure you. Pop the clamps on and when you're sitting comfortably, I'll start the programme. Please count the shocks." Counting was just to stop the volunteers gritting their teeth throughout, it didn't matter whether they counted correctly or not.

Rebecca stared at her for a moment. Several hours at one shock per second was…a lot of shocks! With a gulp, she picked up the clamps and attached them to her labia, crushing the sensitive flesh between serrated jaws. Then she sat back down and tried to prepare mentally for the ordeal, but there really was no way to prepare.

The first shock made her whole body jerk and she yelped, but remembered that she had to count and managed to grunt out one just as the second shock hit. She had received punishment shocks many times before, but holding still and counting without screaming made this time the worst, even before taking the much greater number of shocks into account. Rebecca was a sobbing wreck long before the session was over, but she somehow managed to endure nearly a minute of agony and complete the test to Savindra's satisfaction. The brunette told her she could take a moment to freshen up and she rushed for the bathroom, barely noticing the pain of removing the clamps.

Rebecca splashed water on her face and hoped her heartrate would return to normal, but was scared to keep her tester waiting too long, so went back before she was truly ready, if it was ever possible to be ready for the next part.

"Hi, welcome back," the brunette said brightly. "Are you sure you're ready? Okay, in that case, you can connect the control box, but keep the other device nearby, because we'll probably need it later. Same as before, but only ten shocks this time. Should be easy, right?" She laughed at her own joke.

Rebecca again tried to prepare, but this time the shock was so intense that she couldn't help screaming at the top of her lungs. She drew breath and screamed again, then raised her arm and bit the back of her hand in anguish. As the shocks continued, she thrashed and writhed until she ended up on the floor, out of sight of the webcam. Finally, the tenth shock faded away and she was left weeping in horror at the realization of how bad punishments were going to be from now on.

"Rebecca? Are you there?"

Inwardly, she cursed the annoying voice, but **** herself to get back in her chair.

"Did you forget what I told you? You need to sit still, arms by your sides, no screaming or swearing and count the shocks. If you're ready, I'll repeat the ten."

"Nooo!" The redhead squealed in terror, but it was too late. The searing agony exploded through her clitoris, although it felt like every nerve in her whole body was on fire, not just one area. She howled, grabbing the leads and trying vainly to yank them off, then pulling the other ends, but they remained fastened stubbornly to the box. She pushed the release, but Savindra had disabled it remotely and the box was securely fastened shut with a special type of screw to prevent tampering. Ten seconds later, the shocks stopped again, but Rebecca's ordeal was far from over.

"I'm going to give you one more chance," the voice from the computer came sternly. "If you do not follow my instructions this time, I will administer a punishment of thirty shocks and then we will continue where we left off."

Rebecca returned to her seat in despair. There was no escape, but she didn't know how she was going to complete the task set for her, which seemed almost impossible. However, perhaps due to exhaustion, the third time she did succeed, even though the pain was no less severe. When the tenth shock subsided and her muscles relaxed, she started to sob with relief.

"That's what you should have done the first time. You're only causing yourself more problems by making a fuss. Now, you know there's one more question I need to ask. Which was worse, fifty through the clamps or ten through the electrodes?"

"Ten. Ten was worse! So much worse."

"Alright." Savindra released the electrodes, to her subject's relief. "That means you need to put the clamps back on for another fifty, I'm afraid."

Rebecca never thought she would be relieved to clamp her labia, but she obeyed with alacrity. What would once have been her worst punishment was nothing compared with the suffering her new implants could cause. Savindra didn't even bother to watch the final part of the experimental session, signing off whilst her subject convulsed in her chair. It had taken longer than it was supposed to do and if she was late for the next volunteer, she would be in trouble herself. As she saved her observations to the database, she hoped the evening session would go more smoothly.
