A Theorem of Chastity and Lust

Rebecca Collins suspected there was at least a decent chance that she was going to fail Calculus no matter what she did. It was practically a coin toss at this point. The midterms were long past now, and whatever remaining assignments there were left in the class wouldn’t do much for her grade even if she got the full points. The final exam was scheduled to take place next week, and with it counting as a whole 50% of her grade, there was little she could do but put her hands together and pray. As long as she scored above a ninety-one, she would pass with a C minus. Below that though, and she would have to repeat the class. She regretted now not paying more attention to her math classes back in high school. Here she was in her first semester of college and already her future wasn’t looking very bright.

Sitting in the middle of class however, Rebecca had a much bigger problem on her hands, or rather, between her legs. She needed to cum, and she needed to do so now. Her hand crept down towards the waistband of her skirt but with the heavy steel weight of her chastity belt wrapped around her waist, there was nothing she could do but endure as Professor Flenory continued on with his lecture.

“…now, to calculate the area under the curve, we’ll need to take the anti-derivative and…,” he droned on, and Rebecca felt as if the world was slowly slipping away from under her feet. She stared up at the clock in desperation.

Even now, after four and a half months of classes, the writing on the backboard was all but Greek to her. In a way, it literally was. Scrawled out over the course of the hour-long review session, a cacophony of esoteric symbols filled the dark surface like letters gone mad. Alphas and Betas danced over Phis and Thetas amid circles of missing X’s and squares in both senses of the word. Rebecca watched as the professor drew a penis on the board. No wait, that wasn’t a penis, that was the variable n being divided by an infinity sign. At this point though, it was next to impossible to tell. The fact that she had been locked up in chastity this entire time also wasn’t helping.

“…and thus, as the limit approaches infinity, the value of the equation approaches zero. Any questions?” asked Professor Flenory.

Rebecca had a question. She had several hundred questions, though none of them seemed to be able to make their way out of her throat. Among them, why was calculus so hard, and what did any of this had to do with her degree of wanting to be a programmer? All she wanted to do was to make video games, not calculate the intersection of a circle with respect to a line.

There was a moment of awkwardness as Professor Flenory looked about the room in disappointment. He put down his chalk and let out a sigh.

“Right. Well, if there are no questions, that’ll be all for today. The test will begin on Monday morning at 8:00am sharp. Bring your pencils and one sheet of blank paper only. No calculators allowed,” he said.

There was a dull roar as the fifty or so students in the classroom scrambled to grab their belongings and be the first one out the door. Stuffing her half-finished notes into her backpack, Rebecca got up from her chair to join them as well. Her core throbbed as she squeezed her legs together, doing her best to ignore the heat down below. Before she could escape however, a hand grabbed onto her shoulder, almost knocking her to the floor.

“Heeeyyyy! Rebecca!”

Rebecca turned to find herself face to face with a certain Alice Mcauley, resident blonde and fellow student in the class. Tall, beautiful, and with a personality that would make the Buddha himself blush, she was everything a girl dreamed to be. Well, everyone who had only spoken to her for less than fifteen minutes at a time. To Rebecca who had known her now for almost a quarter of the year, Alice was the last person she wanted to see. The only reason why they knew each other at all was because they had worked together on a project once and the girl had stuck around ever since. Apparently, that made them friends now, or something along those lines.

“How ya doing, ready for the test?” said Alice.

“Alice, why are you here?” said Rebecca.

“The Epsilon Psi sorority is going to have a party tonight,” said Alice.

Rebecca paused, wary of what she knew was coming next.

“Do you have an invitation?” asked Rebecca.

“No,” said Alice.

“Then why are you-…,” began Rebecca but Alice but her off.

“We’ll sneak in,” said Alice.

She smiled as if she had thought of the most brilliant plan in the world.

“We’ll wait until nobody is looking, and then we’ll sneak in and have the time of our lives,” said Alice.

Rebecca sighed. She didn’t have time to deal with this right now. Besides, she had something else more important to take care of at the moment, and the faster she could get back to her dorm, the faster she could get it over with. Shifting her bag on her shoulders, she tried to think of an excuse.

“Alice, you do realize the final exam is next week, right?” said Rebecca.

“Yeah?” said Alice.

“Are you ready?” asked Rebecca.

“No,” said Alice.

Rebecca blinked and resisted the urge to rub her eyes.

“I’m going to fail anyways, so I’ll just retake the class next semester, right?” said Alice.

Somehow, against all odds, this was probably one of the few times that Alice turned out to be right. Rebecca tried to think of a response to say. Out of everyone else in the class however, Alice was probably the only one who had a score lower than hers. If she was going to have a hard time passing, then Rebecca didn’t even want to think about what it was like for Alice.

“I can’t… it’s not…,” she said.

“Come on, it’ll be fun,” said Alice.

Rebecca thought about it for a second. She seriously thought about it. The offer was tempting, much more tempting than trying to cram all of Calculus 1332 into her head over the course of a single weekend. An image filled her head of Alice on the dance floor, blitzed out of her mind and with a drink in each hand. Besides her, she stood with one of her own. A guy stood in front of her, and they were talking. Tall and handsome, his blue eyes stared down into the green, grey lens of her own. His hair was straw brown, and she twirled her own caramel curls around her finger in response. He was shy, she realized, though when his arm reached out to wrap around her shoulder and she turned her head away to blush…

Rebecca shook her head. If she failed the class, not only would that mean that the money she spent would be wasted, but she would also have to delay her graduation by another semester. The latter was what sealed the deal. The money she could afford, but she’d be damned if she was going to stay here a moment longer than the full four years.

“Sorry, but not this time,” said Rebecca.

Alice pouted, though she had enough sense to move out of the way as Rebecca pushed past her on her way out into the hall.

“Next time let’s get wasted,” said Alice.

“After the exams are over,” said Rebecca.

Alice scratched her head.

“When was that again?” she asked.

“Next week,” said Rebecca.

Alice yelled something back in return, but by now Rebecca was too far away to hear. Good thing as well, or she’d be stuck arguing back all day. Rebecca sighed as she made her way back to her dorm. Maybe one day Alice would grow up and learn, though it appeared that today was not the time. As she climbed up the stairs to reach her floor, she winced as the movement caused her clit to throb inside her chastity belt. It was going to be a long while before the torment of finals was going to end.

Phila, her roommate, greeted her as Rebecca entered the dorm they shared together.

“Hey, how was class?” asked Phila.

Phila was sprawled out across the couch, remote in one hand and a bucket of popcorn in the other. A movie was playing on the TV in front of her. She hit the pause button and the actors froze in place, mid coitus and halfway through a kiss. Rebecca stopped and started at the screen. The universe was not doing her any favors today.

“The usual,” said Rebecca.

She headed off towards the kitchen to grab a glass of water. Behind her, the scene resumed as Phila hit the play button and a loud moan came through the speakers. Rebecca turned around, ignoring the building sense of heat and despair. Heat from the awfulness of the movie, she reminded herself, and not from elsewhere.

“Why do you keep watching that stupid movie?” asked Rebecca.

“Because I like it,” said Phila.

“Yeah, but why?” asked Rebecca.

She watched as the actors kissed again and pronounced their love for each other once more. The explosions in the distance grew louder. So did the sound of sex.

“This is the stupidest-…” said Rebecca, but Phila shushed her.

“Hold up, this is the best part,” she said.

Mid climax, both figuratively and literally, an alien appeared and the characters cried out loud in surprise as they were eaten. At least, Rebecca assumed it was surprise, and she assumed it was an alien. It was hard to tell with the quality of the production sometimes. A flight of fighter jets flew overhead to drop a bomb on the alien, and then the screen faded to black. The credits began to roll.

“I liked the book better,” said Rebecca.

“Hey, don’t dig it just because you couldn’t finish it the first time I made you watch it. The Netflix adaptation of Frankenstein is great,” said Phila.

“You have no taste,” said Rebecca.

Swallowing the last of her water, Rebecca headed towards her room as Phila started another movie.

“You sure you don’t want to stay for some Netflix and chill?” asked Phila.

“That doesn’t mean what you think it means,” said Rebecca.

“What do you mean?” said Phila.

“Nevermind,” said Rebecca.

She closed the door behind her, and the sound of the TV died out to a low hum in the background. The rooms weren’t exactly soundproof, but they were good enough to block out the majority of noises that came through. Good thing as well, considering what she was about to do next.

Setting aside her schoolbag, Rebecca took out her laptop and set it on her table. Her heart beat in her chest as she powered it on and navigated to a text file on her desktop. Inside was a single url connected to the university’s domain, innocent enough to avoid notice by any prying eyes though she knew it was anything but. She pasted it into her browser, and a simple chat box came up on the screen. At the top of her laptop, the light of her camera turned on.

Hello, Ms. Collins.

“Hello,” whispered Rebecca.

State your report for the week.

“I really want to cum,” said Rebecca.

There was no response.

“Final exams are next week,” she said.

Again, no response. Rebecca bowed her head. She was going to have to do better if she wanted to make any headway. She took a deep breath and stared into the camera above the screen.

“Today, I tried to touch myself in class but the chastity belt stopped me. I didn’t even realize I was doing it as well until I felt my fingers touch the shield on the belt. I feel like all I need is five seconds without the belt and then I’ll explode. I haven’t never gone without an orgasm for as long as I have right now.,” she said.

Continue.

“Please, I really want to cum. I’ll do absolutely anything you want, but I just can’t take it anymore. I need to cum,” said Rebecca.

There was a brief moment of silence, and a word appeared on the screen.

Adequate.

Rebecca bowed her head in shame. She felt like she wanted to melt into the floor and die. No matter how many times she had to do this, she would never get used to the embarrassment of having to say such things. The screen flickered, and a new interface popped up before her eyes. The chat box still remained, but a number appeared up on the screen.

Total Debt: -$208,000

Amount Repaid: $14,500

Debt Remaining: -$193,500

Looking away to the side, Rebecca slowly began to pull her shirt up over her head. She reached around to take off her bra, and the camera captured every movement as her breasts appeared on the screen. They were small compared to most girls she knew, but she blushed all the same. Her skirt and panties were next and standing up from her chair, she kicked the discarded clothing aside with her feet. Standing fully naked now, her nipples stiffened until they pointed straight into the air.

Present please.

Taking a step back so that her entire body was in frame, Rebecca slowly turned in place so that every inch of her body could be seen. Halfway through, she bent over with her back to the camera and reached behind herself to spread her cheeks. Even though she was unable to see the results, her face turned bright red as she imagined the position she was in. The shield of her chastity belt would at least cover her down there, but an opening was left in the back of the belt to allow for everyday use and no doubt the tight ring of her backdoor would be on full display. After holding the pose for a full thirty seconds, she stood up and turned back around.

Adequate. You may begin.

There was a beep, and then two things happened at once. First, a timer appeared on the screen and began to count down from a period of one hour. A moment later, prompted by a wireless signal, the shield of her chastity belt came free. The belt itself still remained around her waist, but with the crotch piece gone, there was now an empty space around three inches long and an inch wide where it used to be. Rebecca shivered as she felt the cool air of the room brush up against her now exposed core. She didn’t have time to think about such things at the moment though. Gritting her teeth together, she shifted her laptop so it had a good view of her bed. Then, laying down on her back with her legs spread open to either side, she reached down and began to touch her clit.

The task was simple. For the next hour, she would have to edge for the camera, not stopping until the time was up. During that one hour, she would not be allowed to stop or to cum. If she got close to the edge, she would have to announce out loud that she was about to cum, after which she would be allowed a three-minute break to cool back down. After the grace period ended however, she would have to resume until the hour was up.

“Oohhhh…. Fuck…”

Rebecca gasped as she massaged her clit with her fingers. Today was Friday, which meant that this week was the sixteenth week since she started college as a freshman. That also made this week the sixteenth week since the contract she signed began. Eight months ago, it had seemed like a good deal as part of a new scholarship package offered by the university. Now though, with the last orgasm she had a distant memory in the back of her mind, she was on the verge of regretting it.

Rebecca glanced at the numbers on the screen and shook her head. There was no way she could give up after only a single semester. Her legs trembled with the effort of the edge, but she continued to play with her clit. Through the door, she could hear the sound of the TV outside and she bit down on her lips to keep her voice down in her throat. Hopefully, Phila was too busy watching her movie to hear.

Two hundred thousand dollars for four years of education and denial. It was a small price to pay considering that it was the only way she could attend such an expensive and private school. Her family wasn’t poor by any means, but without any other scholarships to her name, they had nowhere close enough. Unless she wanted to take out a federal loan, she would have to settle for a lower ranking school. That was, until she received a letter through the mail. As part of a new study, the university was looking for students who were willing to participate in research revolving around long-term female orgasm denial. If she decided to put her name down for consideration, her tuition would be waived, though certain conditions had to be met.

First, for the next four years or approximately two hundred weeks until she graduated, she would have to wear a chastity belt to prevent any irregularities to the experimental results. On top of that were the regular data gathering sessions that took place each week. Each time she completed a session, a thousand dollars would be struck off her debt, but only if she held herself back and prevented herself from having an orgasm. If she wasn’t able to hold herself back, then the total amount would stay the same. That meant that as long as she could avoid going over the edge, she would be able to graduate debt free but every time she messed up, she was a thousand deeper in the hole.

“Not yet… just a little more…”

Rebecca looked up at the timer on the screen. There was still fifty one minutes and forty three seconds remaining and already she felt herself climbing up the hill towards the cliff at the end. After four months of nonstop edging with no relief in between, it was a miracle she still hadn’t hit the edge.

51:37

51:25

51:19

It was as if the timer was slowing down with each second that passed and Rebecca screamed in frustration in her head. Her clit throbbed underneath her fingers and every cell in her body screamed at her to hurry up, but she ignored the desire and instead kept the same pace. Slowly, she continued to massage around the sensitive nub, touching briefly each time she made contact before pulling away. The longer she could avoid the inevitable, the better the rest of the hour would go.

Hope could only last so long however and soon, Rebecca hit the limit of her endurance. Fueled by months of pent-up denial, her body finally gave in. Moving her fingers away, she placed her hands on both sides of her labia and pulled to the side. Though she always hated it, this was the standard position she was suppose to take every time she had to stop.

“I’m cumming!”

On screen, she watched her clit throbbed in desperation as the stimulation was removed leaving it aching and denied. Her hips thrust forward on their own as they tried to seek out the final bit of friction that would send her over the edge. They met nothing but empty air however, and Rebecca moaned as she felt the walls of her tunnel clench down against the painful nothingness inside.

The timer flickered as it paused, and below it another one for three minutes began. Still holding herself open, Rebecca waited for her body to cool down enough to continue. That had been close, way too close for comfort. Another second longer and it would have been too late. Of course, if she did go over, she could always choose to ruin her orgasm instead to take only half the normal amount off, but the feeling of a ruined orgasm without any pleasure was almost worse than not having one at all. She had found that out the hard way the first time it happened. The frustration afterwards had kept her up the entire night while her fingers scratched at the shield of her chastity belt in a futile attempt to relieve the aching below. The following week, she made sure to go extra slow to ensure it didn’t happen again.

Grace period over, please resume.

The timer resumed, and Rebecca moved her hand back towards her clit. She flinched as her fingers made contact with the exposed nub. Having just been denied an orgasm, she was extra sensitive now and each touch of her fingers felt like a dozen at once. Using one hand to pull back the hood, she took a deep breath as she began the second round of edging.

46:23

Almost a quarter of the way there now. The problem was however that once she hit the edge a single time, subsequent buildups happened much faster with it taking less and less time in between. In less than half the time it took for her to reach the first one, she was forced to pull her hand away again.

39:52

“God damnit… please…”

Another month of this and she would go insane. As the third and then fourth round of edging began, her walls clenched down as they tried to seek out anything that wasn’t empty air to squeeze against. Her clit was rock hard, and her head felt like it was floating in the clouds. Somewhere along the way, the timer hit the halfway point and Rebecca bit down hard to stop herself from crying out. Just think about the money, the numbers on the screen. Two hundred thousand dollars was a lot of money, enough to buy a house. She would be leagues ahead of all her peers when she got out.

26:49

“pleasepleasepleaseplease…”

It was her fifth or sixth edge now. Rebecca was starting to lose count. The only thing she knew for sure were that words that poured out of her mouth were a near incoherent mess, but she didn’t care. Nothing seemed to matter now except the never-ending throbbing between her legs. She completed another circle around her clit, and then jerked her hand away as the floor underneath her threatened to come crashing down. Despite the fact that the inside of her room felt like a furnace, she was shivering. Rebecca looked up at the number on the corner of the screen. Eight. She had hit the edge eight times. It was hard to remember anything except her name now.

11:32

The final ten minutes was always the hardest. Rebecca felt like her entire body was made out of lead. It was as if the entire world had shrunk down to only include the area between her legs and her clit. Her entrance throbbed and her bed was a mess. Fluids poured out of her nonstop and down onto her sheets. She would have to throw it all into the washer when she was done.

Edge, stop, edge, stop, edge, stop…

Over and over it went without pause until she felt like she was about to go mad. Five minutes now, and then four and then three. She could barely go a full minute now without having to pause. The counter in the corner flickered up into the double digits and then continued to count.

2:31

2:05

1:53

Two more edges, and then it would be over. Rebecca forced her hand down against her clit once more. Her arm was beyond sore, but she couldn’t quit now, not when she was so close. The timer hit one minute, and she stopped as her body squeezed down. Through the opening of her chastity belt, she could see her entrance opening and closing showing off the thin barrier of her hymen inside. If it wasn’t already bad enough, the fact that she was still a virgin only made everything worst. At best, it would be another four years before she would be able to have a chance of finding a boyfriend. At worst, it would be even longer than that if she couldn’t pass her tests.

The final edge was the hardest, and she powered through it with a grim determination that came with knowing it was the last one. As the timer hit zero and she pulled her hand away, she teetered desperately on the edge. Her walls clenched down once, twice, three times as they threatened to launch into a ruined orgasm that she wouldn’t be able to stop. They squeezed down one last time, and then everything stood still. Inside, Rebecca felt nothing, not even a hint of pleasure that might have told her if she passed or failed. If that had been a ruined orgasm, then it was the most pathetic one she had ever felt. It was only after a full minute that she dared look up to confirm with the screen.

Congratulations on completing your session this week. Your updated account balance is as shown.

Total Debt: -$208,000

Amount Repaid: $15,500

Debt Remaining: -$192,500

There was one last step left for her to do. Placing the shield back over the front of her chastity belt, Rebecca heard another click echo out through the room as it locked back into place. She closed the browser window and shut her laptop down.

She had made it. Another week had passed, and she had reduced the total amount of student debt she owned by a thousand. Now, there were only a hundred and ninety or so more weeks to go. Another three years and eight months of this torture and then she would be done.

Rebecca sighed and got dressed again. Opening her math textbook, she sat down in her chair and turned to the practice section. She placed an empty sheet of paper down next to the first problem while doing her best to ignore the throbbing in her clit. Her task for the week was finished, but the problem of her finals still remained. If she failed, it would undo all the suffering she had endured so far. She signed again as she began to read. It was going to be another long while before the semester ended this year.
