The Fifth Vital Sign · Part 1

The Fifth Vital Sign · Part 1 (1/3)
Next

Hank watched as the college co-eds filed into the room. He concentrated to keep from staring too hard as set after set of youthful breasts, firm buttocks, and nice long legs went passed him. He had to keep them comfortable, for just a little longer, and then they would all be his. These unsuspecting college sophomores and juniors thought they were coming to their first TA session for Psych 501: Intro to Group Behavior. And the girls thought that Hank, the man in his late-20s who was standing by the door as they came in, was the grad student who they had been assigned to for periodic discussion sessions of the course material.

Some of the girls walking in may have thought it a bit odd that their section had ended up being all female, but it wasn't too surprising since the large lecture class was probably three-quarters women anyway. None of the girls were surprised to have received an email earlier that day informing them of the change in their section assignment and meeting location – that sort of thing happened all the time in these big classes. Sadly for the girls, this was in fact not a TA session for Psych 501, and Hank was no grad student. They were, however, about to learn a few things about group behavior.

The girls each took a seat in the circle of 21 chairs that Hank had arranged in the room – one chair for each of the girls plus one for him. The chairs all looked the same to a casual observer, and they all looked fairly ordinary: armless metal chairs with high backs made of metal rungs. But looks could be deceiving, and the girls would find out soon enough that these chairs were by no means ordinary. Hank waited until each chair was full. He certainly didn't want anyone showing up late to this class, so he was glad that no one came more than a minute or after 3PM. They had heeded the small threat he made in his email about tardiness not being tolerated. When they were all seated, he took a deep breath. This was it. All his careful planning rested on a good performance in the next couple of minutes. After that, he'd be home free.

"Welcome to my section of Psych 501," Hank began. He gave a brief introduction of himself and the research he was pretending to be involved in. He sat in his chair at the head of the circle and explained that they would be starting off with an experiment he had designed around measuring the body's vital signs while a person was involved in various group activities. He pulled a collar up from a cord that was attached to the top of his chair and casually clipped it around his neck, directing his class's attention to the large monitors on the walls of the room that now each displayed one of his primary vitals – temperature, pulse rate, blood pressure and respiratory rate.

The line that now scrolled along each monitor was labeled with the number "0" that matched the number taped to the floor in front of Hank's chair. He demonstrated breathing faster so everyone could see the line for his respiratory rate spike upwards. He then explained that the room was set up to read and graph all their vitals at once, which they would use for the group behavior lesson. He asked them to each find the vital sign monitor behind their chair and put it on. (He was careful not to use the word "collar", even though that would have been more accurate.)

And then came the moment of truth. He needed 100% participation for this to work. As it turned out, he had nothing to worry about. Having seen their TA put on one of the collars, most of the girls were perfectly happy to go ahead and clip the collars around their own necks. There were a couple who hesitated, but when they saw their fellow students collar themselves, and saw the numbered lines start appearing on the monitors, they went ahead and put the sensors around their necks as well.

When there were 20 additional lines on the vital sign monitors, each line matching a number taped on the floor in front of one of the girls, Hank let out a breath that he hadn't even realized he'd been holding. He un-clipped his collar and walked over to one of the monitors. The girls, of course, wouldn't be able to un-clip themselves quite so easily. The self-locking collars that they had all closed around their pretty necks would not be coming off until he released them, and that would not be until he had had a good deal of fun. But they were blissfully unaware of that for now and were talking and laughing loudly while trying to get their own lines to spike or drop on the monitors.

He'd let them keep that unawareness for a little longer. He got their attention and quieted them down, then asked that they all take deep slow breaths and try to get all of their lines as low as possible. Hank watched the 20 chests in the room slowly rise and fall, and he mentally patted himself on the back for picking an incredible assortment of hotties. He had blonds and brunettes, big breasted bimbos and petite pixies, toned athletic bodies as well as softer types. And they were all locked into the machine that he had built for them, even though they didn't know it yet.

"All right ladies," Hank said, "Let's get started. Please find the numbered keypad that is attached to the back of your chairs and type in the number of the girl here who you think is dressed most sluttily."

There were a number of murmurs, somewhat surprised, somewhat disgruntled, but the girls all picked up their keypads and started looking around at each others clothes. They were, after all, psychology students, and they were used to having experiments start strangely and be explained in the end. They started making their choices. Hank looked around to guess who they would choose. #3 – the thin girl in a tank top, skin-tight jeans, and heels? #8 – the super-fit chick in the flower print dress that rode up while she sat to expose most of her long, toned legs? #18 – the hottie with fabulous tits that clearly strained against the white blouse she was wearing?

The monitor beeped to indicate that all 20 girls had made their selections. The wining number showed up on the remote control keypad that Hank carried, but before revealing it to his captive audience, he walked over to #18 and placed his hands on her shoulders, saying: "Please direct your attention to the monitor showing heart rate. I will scroll the graph back to where I first asked the question about slutty clothing. You can see that all of your heart rates went up, as is natural coming out of the breathing exercise you had been doing. Then you can see that a few of your lines continue to rise above the others. Can anyone look around and speculate as to why those girls should have had higher heart rates?"

#4, a cute little blonde who was dressed quite conservatively (for now) raised her hand and said, with a clear note of condescension: "The women with higher heart rates were the ones who are wearing more revealing clothing."

"Precisely," Hank concurred. "Humans, and especially women, often like to be anonymous members of a group, so it is understandable that those who worry they might be called out from the group will have elevated heart rates." Hank began to lightly massage #18's shoulders. "Now, scrolling back to the present, you can see that #18 here has a noticeably higher heart rate than the rest of you. 18, am I right in assuming that you think you are the winning slut?"

The girl in front of him was clearly embarrassed, and her heart rate rose even higher as she nodded.

"Now, watch the screen closely as I reveal the actual winner: #10." #10's pulse line shot right up and the girl herself turned red and harrumphed. The well-endowed winner was wearing a loose fitting t-shirt with a very large neckline that could either cover her cleavage or her stomach, but not both. And either way it couldn't hide her nipples, which stood pert on top of breasts that floated loosely in the shirt and were clearly not constrained by any bra. It was the kind of shirt you might wear to bed, and the girl's tight flannel bottoms, that left her calves bare, indicated that she likely had rolled out of bed and came here without changing.

Hank walked over to her, placing his hands on her mostly bear shoulders, and said: "Now, who can try to raise #10's heart rate even further by making a statement that uses the group theory lesson I've just demonstrated."

Most of the girls looked uncomfortable at this, but #4, the prude, raised her hand high and said "She looks like a morning-after whore, and it's no surprise that most of us picked her as the biggest slut."

This berating did indeed raise #10's heart rate, and also caused her to murmur: "you little bitch.." which Hank quickly cut off saying: "Now, now, #4 was just following directions. Please don't speak unless you are called on. Would anyone else like to try?"

#4's comments served to open the flood gates, and soon almost all of the girls had said something disparaging about the pajama girl that sat under Hank's hands, absorbing the criticism and achieving a higher and higher heart rate.

"Okay, okay," Hank cut in, "let's give the little slut a rest and move on." Hank thought the girl might try to leave right then, but apparently she was too embarrassed to do anything, and just took his insult on top of all the rest. "Now, keeping what you've learned in mind, I'd like you to answer the following question on your keypads: which of these three activities are likely to raise body temperature the most: 1) jumping jacks, 2) a slap in the face, or 3) masturbation?"

The girls giggled at the word 'masturbation.' When they had chosen, Hank graphed their answers on the monitors, a fairly even distribution of each. He then said: "Okay, I need a volunteer to demonstration the first option: jumping jacks." To Hank's pleasure, #8, the athletic girl in the short flower dress, raised her hand, saying that she had picked that answer and knew it was right. Hank asked her to go ahead and do jumping jacks for one minute. The girl got up, but found that she couldn't stand fully erect in front of her chair due to the length of the tether connecting her collar to the back of her chair, so walked around behind the chair and started the exercise there.

Hank chuckled to himself that the girl had clearly seen this as a minor inconvenience due to the necessary equipment and not as a sever limitation to her own freedom. That would change. As the girl jumped away, the thin rungs of her chair's back didn't hide much of her body. Her long bare legs flashed on either side of the chair, and her breasts bounced up and down above the chair's back. Hank watched the show with clear lust in his eyes, not caring much if it creeped-out his subjects at this point.

After a minute, #8 took her seat, breathing heavily. Her temperature had indeed gone up, half a degree, and she looked proud of herself. "Now," Hank continued, "I need a volunteer to slap one of their neighbors. Most of the girls looked fairly surprised at this request, but #10, the winning slut, raised her hand high, clearly ready to dish back some punishment. Hank stood behind #9, a slender raven-haired girl in a black tank top who had definitely participated in mocking #10. Hank surprised the girl by grabbing her wrists and twisting her arms around the back of her chair. Then, before she could react, he told #10 to give her a solid slap across the face.

The pissed off pajama girl was more than happy to oblige. Her tether gave her just enough room to move over to #9 and deliver the requested slap nice and hard. Hank held #9's wrists for a moment longer as she shouted "Hey! That hurt! Let me go!" Hank released her wrists a moment after she started to struggle, and pointed out that her temperature had risen one full degree. He explained that the slap had triggered a 'fight' reaction, which was more powerful than simple exercise. He patted #9 on the head and thanked her for demonstrating.

She looked like she wanted to protest more, but then just closed her mouth, probably thinking that he had made a reasonable scientific point even if she didn't like it.

"Now," Hank said, "I need someone to demonstrate masturbation. Volunteers?" Unsurprisingly, none of the girls raised their hands. "All right, I'll have you vote for the 'volunteer.' Please select someone on your keypads. Oh, and if you don't vote, you'll be it!" That got them voting quickly. The near unanimous winner was again #10, who the girls were already accustomed to picking on, and who anyway had been pretty mean when slapping the girl next to her. #10, however, immediately said that she wouldn't do it. Hank calmly picked up a blanket from a shelf and threw it over the girl's lap, explaining that no one would have to see anything. Unsurprisingly, she still refused.

Hank told her: "Look, this really isn't a request. We need someone to do this demonstration, and you've been chosen fair and square by your classmates. Now, if you don't comply, I'm going to have to give you a 0 for your participation grade, and you'll probably be on my bad side for the rest of the course. So, what's it going to be?"

Hank didn't really expect her to agree, and got ready to introduce the girls to some of the other capabilities of their 'vital sign readers,' but then, to his pleasant surprise, the girl said "fine, I'll do it." Hank laughed to himself. What a slut! He handed her a vibrator and told her to proceed for the same one minute that #8 had spent doing jumping jacks. The rest of the girls giggled as the vibrator came on and #10 let some unintended moans slip out. The vibrator Hank had given her only had one setting, and it was pretty powerful. The girl's temperature definitely started rising, and by the end of the minute she was clearly close to an orgasm.

Hank let her know she could stop, but the aroused girl kept going for a moment longer before exploding in an orgasm, to the laughs and jeers of the other girls in the class. Her temperature had indeed gone up, 1.5 degrees, and Hank explained that compared to exercise and a fight reflex, the human response to sex is the most powerful. He also pointed out on the monitors that most of the girls' temperatures had risen slightly during the display, explaining that they were clearly thinking about sex while #10 masturbated, and that just the thought could raise their temperatures. This made a lot of them uncomfortable, but Hank didn't care about that anymore.

The fake TA decided it was time to take his girls to the next level. "Girls, can any of you tell me what the 5th vital sign is?" #14, a tanned brunette who was made-up and dressed very smartly in a long sleeve blouse and black skirt over some very fine-looking stockinged legs, raised her hand. "The 5th vital sign usually refers to pain."

"Exactly." Hank confirmed. "Pain is generally measured on a scale of 0-10. Your collars are capable of measuring this vital sign as well. However, because everyone experiences pain differently, they first need to be calibrated. To do that, your collars will deliver an electric shock to your throats that will be defined as on the pain scale. They will then compare future pain readings to that baseline. Please direct your attention to the monitor on the far wall." He pointed to a monitor that had so far been blank.

Hank's audience looked decidedly uncomfortable at this development. For one, he had used the word 'collar' for the first time instead of 'vital sign monitor.' And the prospect of receiving an electric shock certainly wasn't appealing. Before anyone voiced a protest, Hank hit a button on his remote. In unison, all 20 girls screamed in surprise and in pain. 20 lines appeared on the blank monitor and shot up, then quickly leveled off at the midpoint on the scale. The electric shock only lasted a couple of seconds, but it had been quite painful, and it left the girls quite upset. #14, who had given the pain definition, said: "Hey, you had no right to do that without our consent." A few other girls voiced their own displeasure, and Hank could see that a couple were fumbling with the clips on their collars.

Hank got everyone's attention and said: "I understand that the calibration was painful, but it was necessary. Now, the next step of this experiment requires that you all remain completely silent. To ensure this, I am activating a function on your collars that will sense any movement of your vocal cords and immediately deliver a painful shock."

Again, #14 tried to explain the rules of consent in experimentation, but all she said was "You.." before she let out a yelp of pain. To her credit, she tried again, but was again cut off. A number of the other girls tried to chime in at this point. You could see which ones tried by looking at the pain lines on the monitor that jumped up to as the punishment was administered. The room quickly grew silent. Most of the girls then tried to pull their collars off, but they quickly found that any pulling on their collars caused them to get shocked as well. And what's more, they found that their tethers had retracted all the way into their chairs, pulling their necks tightly against the backs of their chairs and preventing them from standing up. The chairs themselves were bolted to the floor, leaving the girls stuck exactly where they were.

Hank looked around at his captive class. Some looked scared as they figured out that they were quite thoroughly trapped, others looked mad as hell. He decided to keep the ruse of the 'experiment' going. When the last of the spikes in the pain graph settled down, indicating that the last of the girls had given up on trying to speak or break free from their collars, Hank said: "You have all discovered that your collars will punish you for trying to remove them as well as for speaking. This is necessary to protect the electronics in the collar, which are rather delicate and expensive.

Now, to continue, the next part of this experiment is to time how long it takes for you to do an activity that you would likely prefer not to do. In my research, I am trying to demonstrate that when one member of a group has already performed an activity, then the other members will be faster in performing it. This first activity will set a baseline, so you will all be asked time to do the activity at the same. Every five seconds, all of you will receive a shock from your collars until all of you have performed the activity. This way, the stragglers will be getting peer pressure from those of you who have already done the activity but are still getting shocked.

Are there any questions before we begin?"

#18, the hottie with the great tits straining against her blouse, started to ask something but immediately got shocked. She might not be the sharpest tool in the shed. Hank explained again the importance of them all being silent during this exercise so that the peer pressure on the stragglers was only felt and not heard. Then, with the girls sufficiently anxious, Hank said: "All right – your first activity will be to remove all clothing above your waists and sit with your hands at your sides. If you are wearing a dress, you'll have to remove the whole thing. Begin now."

The girls spent the first 5 seconds looking around at each other in surprise, then all of their pain lines jumped to as the first shock hit them. This caused some to cross their arms defiantly, and caused others to start reaching for the bottoms of their shirts. After the second shock hit, 3 of the weaker girls went ahead and pulled shirts over their heads. Hank reminded them that the activity required all clothing above the waist to come off, which included bras. After the third shock, those first 3 girls then unhooked their bras and pulled them off as well, freeing their breasts for Hank and the rest of the girls to see. Slender #9, who had gotten slapped, was among the three. Her pert B-cup breasts were very nicely shaped and stood tall on her fantastic body. #18 had also removed blouse and bra, and her big C-cup knockers were on beautiful display.

After a 4th shock hit, and after seeing three of their friends strip, another small group of girls started baring their breasts. Hank had to remind them that they needed to keep their arms by their sides in order to be considered 'complete' with the activity. But even then, the topless girls were still getting shocked for their fellow students’ reluctance, and they started looking desperately at the girls who were still clothed. The 5th and 6th shocks brought more into compliance. Hank was on cloud 9. The array of naked tits around him was better than he could have possibly hoped for. There wasn't a single surf-board in the group. Even the skinniest girls had really nicely shaped boobs, and there were quite a number of D cups in the group. This was going to be a blast.

There were now only four stubborn prudes left clothed, with the other 16 topless girls staring vehemently at them. #8, the jumping-jacker in the dress, probably thought it wasn't fair that she would be left in just panties, but after another shock, she apparently couldn't take it anymore and went ahead with pulling her dress off. She really did have a fantastic body, which was now naked except for some skimpy black panties.

#4, the blonde prissy prude, was the last one to strip. It was clear that she was furious, and equally clear that all the other girls were furious at her. The already topless girls kept looking desperately at Hank, probably wanting him to intervene, but of course he had no intention of doing so. The 9th and 10th shocks hit the group, and still #4 sat defiantly. She finally gave in after shock 11, but it took her a full ten seconds and two more shocks to get all her layers off and for her to put her arms by her sides. To everyone's amazement, the prude had a pair of small playboy bunnies tattooed on the insides of her well-endowed breasts. Hank laughed heartily, guessing that those little tatts were the reason she had held out so long, not wanting to reveal that she wasn't actually as up-tight as she made out to be.

"One minute 6 seconds," Hank announced as he walked around collecting clothing into a large plastic bag. "Not bad. Though I'll take note that many of you acted like typical college girls by stripping quite readily, while only a few of you prudes took more time." Some of the girls tried to kick or grab him as he came by, but a quick button push that delivered a collective punishment put that to an end. Many of the girls had been wearing shirts that didn't button or zip all the way down. Those pieces of clothing were dangling off the backs of their chairs, unable to get around the locked collars. Hank continued lecturing about how seeing some girls strip convinced other girls to strip.

As he did so, he walked behind the ring of chairs with a pair of scissors and cut the dangling clothing free. The girls clearly weren't happy about this, or about being lectured on their forced group activity, or about being topless and collared and shocked. But keeping them happy was no longer a concern. Hank kept the ruse of the 'experiment' because he was sure it must be driving them crazy. This had to be about as scientifically valid as creationism, and Hank was sure that a number of these college hotties would have loved to point that out to him.. but they couldn't!

When all the clothing was safely out of reach of the topless captives, Hank continued: "Your next activity will test self-control and the concept of delayed gratification, or in this case, reduced future pain. You will each have the opportunity to cause yourselves pain by squeezing your nipples, with the goal of bringing your pain line on the monitor up to a target level. If you are unsuccessful, your collar will deliver a 10-second long shock at a punishment level. The target level will begin at and will slowly increase the longer you delay. The punishment level will always be set 2 steps above the target level. If the punishment level gets to 10 before you have begun, then you will receive a 10-second shock at , w
