Erotica Sex Story: Rebecca Collins is a freshman in college who has a big problem. She is forced to wear a chastity belt 24/7 as part of her scholarship contract. While her tuition is waived, she must now go without orgasm for the next four years. That’s not all however. As part of a research program on female orgasm denial, she must also edge in front of a camera every week for an entire hour at a time. Faced with these difficult tasks, will she manage to graduate on time?

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.
