Edged For Science Ch. 03

"AHAHAHAAHAH- MA-AHAHAH- MAKE IT STO-AAHAHAHAHAHA-"

Klara had now been strapped to the machine and edged... How many times? She had lost count at about fifteen. Every time it was the same - she would be taken to the very edge of an orgasm, before being brought right back down by the most intense tickling she had ever experienced. And by now, the machine had adapted to Klara so well that it actually took her to the literal edge of her orgasm each time. Just one touch away from riding the tidal wave of pleasure. But the wave never came for Klara.

No, because Klara had signed up to a study investigating the effects of tickling on preventing an orgasm. So of course, this is exactly what was going to happen. If she had actually read about the experiment before immediately volunteering, maybe she wouldn't be in this mess. Maybe she wouldn't be wildly thrashing around in her restraints, begging for an end to all of this. Trying her hardest to spare her glistening clit from the relentless feathers constantly stroking up and down it for just one second. Sadly, her thrashing was inconsequential as her pussy was fixed in place, providing easy access for the assailants that tortured her.

Let's not downplay the torment the rest of Klara's body was going through. The machine had switched up its tactics over time, constantly keeping her on edge in more ways than one. At this moment, Klara's legs had been lifted up off the table, and a ring had been fixed around each of her thighs. An outside observer would simply see the rings moving up and down her thighs randomly, but Klara knew that the insides of the rings were lined with hundreds of soft bristles that were unbearable as the rings rotated around her legs at insane speeds. They would constantly surprise Klara by changing the speed and direction of their movement - sometimes slowly moving from her knees right to the edge of her pussy, while other times just rapidly scraping up and down her sensitive thighs. They often paid special attention to her upper thighs, as the machine found that the higher up they went, the louder Klara's screams became.

Klara's ass wasn't free from these bristly attacks either. The machine had deployed two special tentacles for her backside. These tentacles had rollers on their ends, also lined with the same torturous bristles. Klara couldn't believe how soft the bristles were as the rollers spun at high speeds while stroking all around her exposed butt cheeks. All she could do was giggle uncontrollably as the she felt her ass being stretched open and a roller nestling itself horizontally, directly between her cheeks. Klara frantically tried to shake her ass away from the ordeal but of course, she could not budge, and the rollers continued to administer their treatment. More of them joined the party and targeted the rest of her lower waist, including the insanely sensitive patch of skin above Klara's pussy, as well as any part of her outer pussy they could find outside the cup that was still covering her most private parts, all while Klara begged for mercy from the unrelenting machine.

Klara's upper body was also going through an equally devious ordeal. With her hands still stretched taut above her head, her pits were completely exposed to the mechanical fingers that were digging into them without ever needing to rest. At some point, the fingers even began to vibrate powerfully, making them even more unimaginably ticklish to her armpits. Below her breasts, Klara's belly and sides were subject to hellish torments by several strange balls that had started rolling around her body. The balls would have been perfectly bearable if it wasn't for the feathery tendrils they were entirely covered in. As the round spheres twisted and rotated while moving around Klara's soft skin, she cackled uncontrollably while trying to jerk her body away from the devious attacks. Klara tried increasingly hard to escape her torment as the balls scraped around between each of her ribs, much to her ticklish dismay.

But none of this compared to what Klara's tits were experiencing. The fact that she couldn't see what was going on under the solid cups that covered them heightened how badly they tickled, as she never knew what to expect. Sometimes she would feel soft feathers scraping all around her globes, paying special attention to her needy nipples while she screamed in tortured ecstasy. Other times, she would thrash around in her bonds while robot hands roughly squeezed and tickled her all over her breasts while flicking her rock hard nipples at every opportunity. At this point, two bullet vibrators had been applied on her, one pressed up against each of her nipples, driving her wild with arousal while also tickling her to no end as she struggled against her straps. More bullet vibrators had also been placed in and around Klara's wet pussy, and while she was thankful for the stimulation, she cursed the fact that they were set to such a high setting that instead of driving her to a climax, they just provided her with an unbelievably ticklish buzzing sensation. And if she did ever get too close to cumming, the machine would just shut off the vibrators for a few seconds while the constant tickling brought her back down.

After what felt like a lifetime to Klara, the tickling and teasing finally ended and she saw the cups moving away from her tits and pussy, at last being able to see her entire naked body. The tools around the rest of her body also retreated back to their compartments under the table, and Klara let out a sign of relief as she thought about what she was going to do as soon as she got out of the lab. That is, run straight to the toilet and masterbate like an animal.

"Thank God, p-please undo these and let me out of- wait, wait, nonono PLEASE NONO I can't take anymore of this please-"

Klara's pleas were interrupted by the sound of more compartments opening up under her, followed by several new tools setting themselves around her, particularly above her pussy and breasts. These tools were mainly various kinds of feathers ominously looming over Klara's quivering body, and while she dreaded their ticklish touch, right now she was more concerned with not being able to cum for even longer. She couldn't believe there could possibly be more to this insane experiment.

"Now is the hard part of this experiment," Chloe began explaining, while Klara gulped in fear. "As you experienced first-hand, our state-of-the-art machine can easily tease a subject to the physical brink of an orgasm and use tickling to bring them back down as many times as needed, with superhuman accuracy. In fact, I could have simply left you here hooked onto the machine for the rest of the day rather than just the one hour, and you would have still been stuck in this cycle of ticklish denial when I came back tomorrow morning."

It was true, the machine had managed to deny Klara's orgasm with unbelievable accuracy. But what was on her mind was the fact that she had only been relentlessly teased and denied for an hour. Klara had been convinced that her ordeal must have lasted at least a couple hours.

"However, there are ways to be even more efficient in an interrogation. I believe subjects are much more likely to spill their secrets during the teasing part of the cycle, rather than the tickling part. This is partially because they can barely speak while being tickled, but also because the teasing and denial makes them so much more desperate. So, a much more effective interrogation technique would be to constantly keep the subject on the brink of a climax by balancing the tickling and teasing simultaneously, rather than switching between the two and having to bring them back up to the edge every time. Wouldn't you agree?"

Klara shuddered and tried to flinch as she felt a feather land on her left breast and start slowly circling around it. This was followed by a similar fluffy feather landing on her right breast and repeating the same action. Having already been denied for an hour at this point, even the light strokes of the feathers on her tits was enough to give her goosebumps. More landed all around her perky globes and started homing in on their sensitive peaks. After so many edges, Klara's nipples were constantly erect, and the touch of the feathers on her buds was electrifying. Her breathing became deep as moans slipped through her lips, before they began being interspersed with cute giggles.

The brief laughter was being caused by more feathers stroking various parts of Klara's body. A feather had inserted itself into both of her armpits, slowly scraping the skin of her hollows. While it was definitely still tickling her, forcing her to uncontrollable laughter every now and then, this time, the spinning and stroking of the feather was slow enough to actually still be raising her level of arousal. More feathers descended onto Klara's flat stomach, while others approached both sides of her hips. They skittered around her soft body, applying light touches everywhere they could and locating the spots that got them the best reactions from their victim. Klara's sides were seemingly covered with such spots, as every time the feathers moved ever so slightly, and a new part of Klara's silky smooth skin was introduced to them, she would break into silent but unstoppable laughter, trying to shake her waist and escape the torturous feathers all around her skin.

But what Klara dreaded the most was the feathers attacking her nether regions. Of course, that is exactly what they went for next. It started on her inner thighs, where, just like everywhere else on her body, feathers of all shapes and sizes began their exploration. Klara's heart rate quickened as they marched up her thighs, towards their clear goal between her legs. Their motions were simple but insanely effective as Klara flinched and shuddered while the feathers sweeped all around her legs, making their way closer and closer to her aching pussy. It didn't take long for her dread to turn into desperation, as Klara how imagined what the soft feathers must feel like on her puffy lips, and best of all, her wet and swollen clit. She needed to feel the feathers there - she needed any physical stimulation she could get to send her over the edge, but it was not meant to be for Klara.

Just as the tormentors reached the very edge of Klara's pussy, they stopped advancing further, instead choosing to skitter around just outside her entrance, not letting her feel their heavenly touch right on her special spot just yet. Klara thrashed around in frustration as her waist was fixed in place, depriving her mound of any physical contact for now. That's not to say the feathers didn't have an impact though. Klara squirmed (or rather, tried to squirm) around as they wreaked havoc on her sensitive inner thighs. As the tickling of her thighs continued without any sign of the feathers blessing her pussy with their angelic strokes, Klara's cries for mercy and release became more and more desperate.

"Pl-pleeehehease please tickle my p-p-pussy -EEHEHEHAHAH- PLEEEHEHEHE- AAAAA-"

Chloe finally gave in to Klara's pleas, and with the press of a button, one particularly long and stiff feather dragged itself from the bottom of her slit to the top, passing directly over her throbbing clit on the way. Klara thought she might explode right there and then, but found herself still shy of sexual release. The feather repeated its motion once again, while other similar feathers also approached Klara's precious pussy. She froze in silent laughter as she felt her entrance being stretched open, followed by the feathery assailants entering her, scraping their hellishly ticklish tendrils all around her inner pussy walls like in the earlier stages of the excitement. There was nothing she could do but take the horrendous ticklish attack inside her. Klara tried to twist her waist away, but as always, found herself helplessly bound to the table. When a particularly soft feather started focusing its attack on her exposed and drooling clit, Klara let out a deep and primal moan as she approached her long-denied orgasm again. It would only take a few more strokes on her hypersensitive button now, just three more...

Two...

One...

But the final stroke never came, and neither did Klara. Even though she had expected this by now, every edge was still more frustrating than the last, and like several times so far, wild screaming and hopeless thrashing ensued when Klara realised it had happened again. The feathers all around the rest of her body continued their ticklish torture, holding Klara off from her sweet release without the feather on her sensitive button. However, unlike before, it only took a few seconds for the feather on her clit to start up again, thrusting her back towards her orgasm. Since her arousal had barely cooled down from before, Klara only lasted half a dozen more strokes on her clit before she reached the very brink of a climax again and the machine had to stop touching her clit.

"Now, my machine is going to attempt to keep you on the very edge of your climax for as long as it can," Chloe explained, as the feather on Klara's clit continued to give it a few slow strokes before stopping for a couple seconds and starting again. "Ideally, it should be able to hold you in that state indefinitely! Sadly, so far it only averages about an hour before the subject is inevitably sent over the edge by the constant stimulation."

Klara's eyes popped wide open on hearing this.

"AN H-HOUR? NONONO I C-CAAA-CAN'T I CAN'T DO THIS, GET -OO OOOO OAA- GET ME OUT OF HERE -EHEHHHEEEHE-"

But Chloe couldn't let that happen.

"I'm sorry, Klara, but I'm afraid I can't allow you to leave at this stage in the experiment. We have gathered a lot of information about you so far and it would be a waste of our resources if you left before completing the experiment. This is why you had to sign the contract outside. Please just try to relax and complete the experiment."

Klara couldn't believe what she was hearing. Try to relax? How could she while being forced to balance on the razor edge of an orgasm for a whole hour? Well, Klara thought, maybe it wouldn't be an hour. The machine only kept subjects on the edge for an average of an hour, so there must be several subjects that ended up cumming a lot earlier. Deep down though, Klara felt as if she wouldn't be one of those women, no matter how much she envied them.

And so the cycle continued. The machine would take Klara to the pinnacle of pleasure before stopping the stimulation on her genitals, as it had been doing throughout the experiment. However, now it would only let her arousal drop for a few seconds before starting the clit feathering again and sending her back towards her climax. On and on the process went, the heavenly feather swiping up and down the entire length of her clit for a few precious seconds, and then holding off for a few more seconds, before stroking again. The feather never gave her pulsing love-button attention for long enough to send Klara over the edge, but at the same time, the stroking was too frequent for her to spend even a second thinking about anything other than her desperate need for release. Just a few minutes ago, Klara hadn't thought anything could be worse than being taken to the edge and tickled all the way back down again and again, but now that she was constantly being held at the brink of her orgasm, she wished the machine would just tickle her mercilessly like before, and give her a break from the edging.

It's not that Klara wasn't being tickled - her body was still being ravaged by all kinds of feathers exploring her most ticklish spots. However, the tickling was different to before. Now the strokes were more teasing, rather than the relentless barrage of vicious tickling she was being put through earlier. In her current circumstances though, this was worse. The soft touches did nothing to quell Klara's arousal, keeping it on a knife's edge without letting it die down. All the while, they continued to elicit sudden shrieks and giggles from her as they found particularly sensitive spots on her sides and pits. That wasn't all, as Klara desperately tried to flinch and escape from more ticklish tendrils that were digging between each of her ribs.

This tickling was being perfectly balanced by more sensual stroking all around Klara's breasts as before. Her cups were entirely covered with the soft touches of the feathers, ensuring that her arousal never dropped, regardless of whether or not her clit was being manipulated. Klara's nipples, now rock hard from the constant stimulation, were still being circled by several fluffy feathers, taking her to the heights of bliss as more feathery attackers sweeped up and down her hypersensitive buds.

The breast tickling was accompanied by many stiff feathers making their way down to Klara's ass. They scribbled away at her butt cheeks from every angle, not relenting for a second as she shuddered at the intensely ticklish feeling. The pitch of Klara's screams rose even more when she felt her ass cheeks being stretched apart, giving the long feathers access to the sensitive skin between them. The machine wasted no time in using those feathers to stroke up and down between her cheeks, slowly enough to keep her arousal high while still causing her to break into uncontrollable laughter every now and then.

The tickling all over Klara's body continued without any breaks as the feathers started and stopped, edging her ten, twenty, thirty times. Every time she was brought just shy of her orgasm, the machine got better and better at keeping her at the edge. Over time, the gap between the feathers stopping and starting got shorter and shorter, meaning Klara was kept closer and closer to release. By now, the machine was able to constantly keep her so close to climaxing that just one stroke of the feather on her clit would make her explode. It would stroke her clit once, then stop for a second or two before doing it again, always too late to actually give her the climax she craved.

"P-p-lease let me g-goo -OOO- how long -AAA- has it b-b-EEEEAAAA-" Klara felt like she had been on the verge of an orgasm for a lifetime.

"Just reaching six minutes, you're doing great!"

Klara let out a deafening scream as the reality of her situation dawned on her. Just six minutes? How was she going to survive an hour of this?

But she had no choice. No matter how much she thrashed against her bonds and cried for mercy from the scientist observing her, the onslaught of feathery attacks continued, while Klara was constantly held a fraction of a second before what would have been a mind-blowing orgasm. The time ticked on and on as the machine successfully did exactly what Chloe had said, keeping Klara on the edge for an hour, but even now it showed no signs of stopping. Chloe intended to keep the machine going until it eventually failed and allowed Klara to climax by accident, and she was thrilled at how well it was doing.

Now and then, the machine changed its tactics in edging Klara, not allowing her to get used to anything in particular. Right now, the feather on her clit had been replaced with a paintbrush delicately stroking her precious button, as if it were a canvas. Unfortunately for Klara, the constant strokes were so light and delivered by such a thin paintbrush, that she merely felt them as an everlasting itch on her drooling clit, lighting the flames of her arousal but not being enough to take her into the depths of pleasure. With her hands secured to the table, there was no way for Klara to satisfy herself, so the machine had tormented her with the itch-inducing brush for the last twenty minutes, and would continue the same for a lot longer still.

But even after another hour of torment, Klara continued to be kept at the brink of pleasure, and Chloe carried on observing her with delight as the machine was performing better than it had with any other subject.
