CJ Gives Herself to Science

And now the probe in her cunt was removed. CJ was about to scream through her gag when suddenly she felt something else pressing against her opening. Jenny was slowly easing it into her tunnel. It felt good, better than good. The size of a nice big cock and CJ could feel a textured surface. She welcomed the sensation of being stretched, opened.

Once again CJ felt a steady hand begin to thrust the probe in and out of her cunt. Jenny was going deep. It was measuring her 'moisture' after all. This probe felt good, though. After those first smaller instruments this one fitted nicely inside her. CJ thought of the sweet young Bess and wondered whether she was going to use any of the apparatus on her.

'Yes, good,' reported Donald loudly. 'OK, lets see what results you can get.'

Now Jenny began to move the probe a little more firmly. CJ realised that she was being fucked by a scientific instrument. And what an instrument it was, especially in the obviously capable hands of the young student. CJ was aware that her breathing was picking up. No doubt the machines were catching all that. She felt her body start to warm. Most of all she felt her cunt respond to finally having some proper stimulation applied to it.

Jenny was firm and insistent with her thrusting. She began to pick up speed. 'How's that showing up?' she asked. 'I'm applying a little more pressure now.'

And she was. The probe was really beginning to work in and out of her cunt. CJ loved to masturbate with her favourite vibrator but even better was having someone else fuck her with one. She knew there were no cocks to be had in this lab. That hardly mattered now as Jenny expertly drove the probe back and forth. CJ could hear herself moaning almost constantly. Her climax was building. So quick! Should she try to hold it in? She knew instantly that it was useless to try.

Someone applied new pressure to her clit. Something was stroking her around the outside of that infernal clamp. Yes, the clamp. Oh god, how good those nasty little clamps felt as they transmitted her arousal and her lust to the watching class.

Thinking about her clit was a mistake. Within seconds CJ felt herself begin to erupt. She did her best to be quiet, struggled to lie still while Jenny fucked her bound body with some kind of device. Oh, but she could hear herself blowing around the gag and knew that her arms and legs had gone rigid underneath the leather straps. She could feel the climax surging though her body and rattling in her brain. It was weeks since she'd been fucked and she'd carefully followed Bess' suggestion that she not masturbate for a week before the experiment.

'Yeah, that's working well,' reported Donald. That was all he could say about CJ's sweet, explosive orgasm. It was her first really 'public' climax. Her first orgasm of this insane experiment. The students had forced it out of her and she felt exposed and ashamed and humiliated and so incredibly turned on.

'Real good,' agreed Bess. 'I want to use number 12 next.' CJ didn't mind too much what they used next. Young Bess was going to touch her. The thought made the remnants of her first orgasm feel even warmer.

'Take your time with this response,' spoke up the firm voice of the professor. 'Make sure you get all the data from this one before you switch.'

Again the class members were asking questions of Donald. They could have asked CJ herself except that she was still tightly gagged. In fact, she reminded herself, in this state they could do whatever they wanted with her -- or to her!

Before her cunt had time to recover, while she felt herself still hot and engorged with blood, the thick probe was removed. CJ was sure the experiment was only getting started. She felt confused -- why was it so arousing to be displayed for these hidden strangers? But she heard the sound of the trolley again and hands were on her cunt, moving and adjusting the sensors and measuring devices they'd placed there earlier.

'Right. Go,' said Donald.

Suddenly CJ felt a new device placed against her cunt lips. She heard Mags offer to help and again tried to focus on the thought of those small, young tits with their long nipples.

Something was being pushed into her, inserted into her hole. Suddenly CJ realised this one was big, really big. Luckily her cunt was till slick but she knew this one would be a struggle. Mags gave another push and CJ couldn't help but grunt in response. It felt about the size of the biggest cock CJ could remember feeling. She tried to make herself relax, to let her cunt stretch around the girth of this new probe. She didn't know if she could handle this much size but the students intended to use it anyway.

'Got it all Donald?' asked Bess. 'Number 9 needs to start as quickly as possible.'

'Fire up,' came his reply. CJ had expected a young man to have his eyes bulging out of his head by now. This boy must be a real science geek.

She felt another nudge and the thing withdrew slightly. There was another nudge and CJ grunted again. Her cunt was full. It felt strange but it felt good. Where they fucking her or not? The probe moved some more, deeper and quicker. Oh, this one was interesting. She wondered for a moment if the students were prepared to hurt her to get their results.

'Second speed.' She heard Mags call out. Then CJ heard a new sound. Then she felt the probe in her tunnel begin to pick up speed. The probe thrust harder and deeper. It was a machine. She was being fucked by a machine while the class watched.

CJ could hear the mechanical sound, a clunk each time the piston was fully extended and the probe was touching her cervix. There was power behind this one, real force. She was being fucked by a machine and she was going to be reamed by the thick thing at the end whether she liked it or not. Actually she rather did like it. She was being stretched and pummelled inside. Her own hand could never have jammed something so large inside her tunnel. There had been that one guy, that one cock, long ago. She tried to recall his name.

But someone was touching her clit. Readjusting the clamp that measured god knew what. They were touching her clit. That big thing was reaming her cunt and someone was touching her clit. Then her arse, they were checking the probe in her butt hole. And still that fat cock was pumping back and forth in her hole. CJ felt so horny, so hungry. She could hear the students asking their questions again. Only this time she was not embarrassed. She forgot all about her thick thighs and her large butt and her pale tits. This time she knew she felt a small twinge of pride that she could take everything they could dream up. They wanted to see her sexual response and she was going to show it to them.

Strapped to the table, unable to move, she could only lie there as the probe moved right to the entrance of her hole and then plunged deep to her cervix. She'd not been touched in some of those places for a long, long time. And the machine, number 9, was doing it over and over and over again. It was almost the perfect fuck.

Suddenly she was cumming -- cumming hard. This time it was huge, so much bigger than the first. CJ heard herself groaning painfully through the soft leather gag. Was that being recorded as well? Her brain was boiling and her body was out of control. She wanted to thrash and moan but she was helpless. The big fake cock just kept pumping in and out. It was merciless. CJ didn't want it to stop. She could feel herself drooling around the gag. Huge spasms were gripping her cunt and she knew her hips were bucking against the leather straps. She wanted to shout out and tell them to 'fuck me!'

Instead the thing in her cunt was slowing. The machine was slowing and the fuck was coming to an end. CJ wanted to protest, to shout out her needs. If they left the thing in her she knew she'd cum again for them.

But the machine had stopped and the probe was being removed. The students were talking amongst themselves, ignoring her needs.

'Number eleven is next Donald,' said Bess. 'Jenny will pump it up as soon as you're ready.' But CJ, with her brain on fire, wasn't listening. She only knew that her cunt was wide and empty. She was hungry, desperate for more. Now she knew she'd done the right thing in agreeing to Bess' proposition. She didn't care about the class using her. She just wanted more orgasms. She needed them right now.

The new probe was shoved into her hole. It was smaller than the machine, almost too small. Though CJ enjoyed the fact it was being inserted by hand. Now she was thrilled to have the young students touch her. Especially Bess and the young Mags with her pointy nipples.

'OK. Good readings now,' called out Donald. 'Go with number eleven.'

Something strange started in CJ's cunt. The new probe seemed to be growing. Had someone mentioned 'pumping'? Yes, she could feel it swelling now, beginning to fill her empty hole. An unseen hand moved it slowly back and forth. That felt much better.

'Nearly ready,' said Bess. CJ could feel the thing still growing inside her. It was already as big as the machine cock and she could feel it wasn't done yet. The hand stopped as the pressure in her cunt became too great. CJ grunted and groaned as her cunt was stretched further than it had ever gone before. Oh, what were they measuring now?

"Right. It's on.' What was?

And then CJ felt it. The instrument was wedged hard inside her cunt. But there was something else, something moving. She could feel it under her pubic bone. Something new was pressing there, vibrating very softly. She didn't know what the hell they stuck inside her. But she could feel it start to rub and buzz against that special spot. She was stuck tight and the probe was jammed in. But somehow the students had designed the perfect tool to massage and stimulate her G-spot.

Fuck, it felt good! CJ's cunt muscles were out of control now as they contracted around the instrument. The buzzing was getting more intense and the pressure on that one spot was growing stronger. She wanted some thrusting but she knew she would cum anyway. CJ had given up worrying about her predicament. The students wanted sexual response and they were getting it from her.

Once more her cunt gripped the apparatus. This time Donald knew he'd caught it on his machines.

'Great. Really good muscle response to this one.' Strangely, his comments only encouraged CJ to relax and let the coming orgasm build inside her. She no longer cared that her cunt was betraying her to the eager students. If only someone would give a little more thrusting.

'Good muscle response is important,' came the professor's firm voice. 'Get some sphincter data as well.'

CJ didn't stop to think what that meant. She knew another orgasm was close and she knew the students would make sure it arrived. So there was a little surprise when she felt something between her butt cheeks. Another unseen hand withdrew the probe from there and CJ felt a small thrill at the sudden sensation.

Instantly some new thing was pressed against her small, dark hole. The new thing was inserted, pushed past her anus and deeper into her bowels. CJ couldn't help but cry out through the leather gag. It wasn't painful at all. In fact this new sensation was incredible. The thing was thicker than the last probe, about two fingers thick and well lubed up. It seemed to fill her passage nicely and CJ was instantly aware that it somehow seemed to make the vibrations in her cunt even more intense.

The device in her cunt was huge and getting bigger. That special piece against her G-spot was certainly working its magic. CJ had never had a vibrator like this one. The pressure and buzzing inside her was beyond description. CJ no longer cared about her big arse or her thick thighs or her blue-veined tits. She was being stimulated in both holes and two students were fucking her at the same time. She only cared about cumming and cumming hard.

Someone was moving the other probe solely back and forth in her arse. It was delicious. The buzzing inside her cunt increased further. And then, without warning, something was applied to her clit, a finger. It was too much for CJ to bear any longer. Immediately she felt her climax tearing through her. This time she could feel herself straining against the leather straps. She knew it was her voice that was screaming out around the soft gag.

Just like before, the students were focussed only on getting their results. CJ was cumming so much harder than she'd thought possible but they just stayed on their tasks. They wanted Donald to get all his data. And CJ didn't care. She wanted them to take their time, she wanted more. She usually enjoyed arse play but was shy about it. This time the sensation was making her orgasm so incredibly intense. Her cunt was spasming around that huge thing inside her and she could feel her juices running down her crack. It was a humiliation but CJ no longer cared, she just wanted them to give her more pleasure.

Another orgasm was following quickly. 'Oh god', she thought to herself, 'that thing is so big and my cunt is still squeezing hard on it.'

Donald was seemingly still fixated on his machines. 'This is very good data. Big responses. Maybe we should try Level 3.'

Then Jenny's voice -- 'Professor, would you give us permission to move to Level 3 stimulation with this subject?'

'Yes, subject D7 seems very suitable,' came the calm reply. 'I'll sign the paperwork now. You may proceed without limits to Level 3.'

CJ was subject D7 and she was close, so close, to her next orgasm. So she was bewildered when suddenly the buzzing in her cunt slowed and the probe in her arse was withdrawn. 'Oh no' she thought to herself. 'Not now, please.' Again she wanted to call out to them, to beg, but the gag muffled her moans of protest. The young students had worked her into a state of frenzy and now they were taking it all away from her.

Suddenly there were hands all over her. On her tits, removing the small clamps. Then her labia and even her clit. The clamps, the measuring devices, were being removed, replaced, shifted and checked. CJ knew the class really was interested in her sexual responses and didn't care about her needs. But she was loving the sensation of their hands pulling and prodding at her.

Something new was being wheeled into place, between her legs. At the same time new clamps were applied to her nipples. And then hands began to stroke her breasts. They were massaging her tits, stroking and squeezing them. The invisible hands were working her tits, from the base to her nipples. CJ knew these were Bess' hands. They were the same hands she'd felt that night at Sarah's house. Oh Bess! CJ was relieved and excited to feel her touch.

But the students were focussed on her holes -- her cunt and her arse. CJ was still dripping wet and panting heavily. The students were pressing something new into her cunt, something hard and thick.

Then she felt something being introduced to her bottom. CJ tried to relax but she was too excited, this was too sudden. She wanted them to fill her up but she didn't want them to hurt her.

The students, however, either didn't care or were simply confident that they knew what to do.

The thing in her cunt wasn't like the inflatable probe. But it was snug and when CJ felt it start to move she knew, she just knew, that the class was having her fucked by a machine once again. She could hear the motor working and feel the cold, relentless way the device shoved in and out of her. Luckily her cunt was still soaking wet because she quickly felt the thing pick up speed. At last the little bastards were fucking her. If only they'd let her cum this time.

Bess was still working her tits and now her cunt was getting some real relief. CJ felt that orgasm starting to build again. That was the moment when someone decided to force the other probe into her butt. CJ couldn't protest and she was helpless to refuse what they were doing to her. Her sphincter easily stretched to accommodate the new thing. The machine in her cunt was really pumping and having her arse filled by complete strangers was actually a thrill. Plus there were Bess' hands still expertly massaging her big tits.

CJ was being fucked for the whole class. Fucked in both holes. The hand working the thing in her bottom was gentle but just as insistent as the machine. They wanted her to cum and CJ knew she was about to oblige them.

She came, came hard. Came loud. They were all watching her and listening. Donald was recording everything. Somehow that made it all the more exciting. CJ thrashed and strained against the leather straps. Her eyes were popping out of her head and her brain was on fire. She wanted to cum good and hard. She wanted to cum for Bess.

Now there was no mercy from the students. CJ was nothing but a test subject. Hell it was like she was being raped by them and their machines. Bess was there. That made it better somehow. But CJ knew Bess was a part of it too.

Before one orgasm had finished the class was working on the next. Her holes were emptied and new devices were inserted into her. No-one stopped to ask CJ what she wanted or what she enjoyed. They had their instruments for that.

The things on her nipples began to send a tingle through her. Suddenly CJ realised that it was electricity. The students were sending an electric current through her nipples. She wanted to gasp aloud but realised she'd lost control of even her throat.

This time the probe in her cunt was big -- really big. Fingers were on her clit, softly rubbing and pinching. The device being inserted into her backdoor felt like it was made of balls. CJ felt each one as the object was pressed into her. Just as quickly she felt them again as they started slowly to work it in and out of her.

The fingers on her clit were driving her wild and she was grateful for the extra stimulation. They were experimenting in her arsehole (or was it an assault?) and somehow CJ found that she was loving the way the students were working on her.

The big device in her cunt wasn't going in so easily. 'Number 15,' came a voice. 'Use 15 first and then try that one again.'

Something soft and buzzing was quickly introduced to her cunt and CJ happily allowed her body to swallow it. She knew her body was out of control as she felt another orgasm swell through her. Orgasms were coming so rapidly that she almost couldn't tell where one ended and the next began. She didn't care, she was desperate to cum and greedily allowed her body and her mind to sink into the multitude of sensations and stimuli that the class was applying to her.

As soon as the next peak passed the class manoeuvred their devices once more. Numbers were called out. CJ could hear them but was too far gone to make any sense of them.

Something started to buzz against her clit. The huge thing was back at her cunt entrance. This time CJ knew the students would force it into her. She didn't mind at all.

Whatever was in her bum slowed briefly. They were all concentrating on her cunt. The new apparatus felt enormous. It was shoved past her entrance. This time she would be properly stretched. CJ wanted to call out her encouragement but she was speechless.

Bit by bit it was forced into her tunnel. CJ had never had anything that size inside her. She wanted to take the whole thing. Her clit was still buzzing and her nipples were still sending amazing shocks through her body. She wanted them to fuck her into oblivion. Whether the students cared about her needs or not, thankfully the experiment meant she got exactly what she wanted.

The huge thing was finally in her cunt. She was impaled, stuck on the monster. Even her cervix was squashed by its bulk. Someone turned on a motor and that thing was being forced back and forth. Every bit of her insides was being touched and stroked by it. They bashed it into her cervix and CJ didn't mind at all. Her entire cunt was being fucked and she knew she was loving it. Impaled like this, even the device in her anus was being squashed up. CJ would have refused such an enormous probe if they'd asked her but luckily the students had not considered it. They wanted to test her response and they wanted that thing inside her.
