She loses the entire outfit

Mackenzie allowed herself to become completely engrossed in the History exam. For the next ninety minutes the only thing that mattered to her was doing well on the midterm. The skimpily dressed redhead raced through the test, answering question after question as best she could.

But Mackenzie's intense focus betrayed her when she absentmindedly shifted her weight the wrong way in her seat. Unbeknownst to her, the seat she was resting on happened to have a crack in the wood. A very big crack running right through the middle of the seat. And when Mackenzie adjusted her weight, the bottom of her shorts got snagged in that crack.

Throughout the rest of the test, Mackenzie shifted her weight back and forth another dozen times or so. This allowed the jagged wood to dig deeper and deeper into the jean fabric, causing her shorts to become more and more ensnared by the seat each time. Each tug of the greedy splinters also pulled the shorts slightly tighter on her shapely hips, causing the zipper to slowly slide lower and lower.

Oblivious to the tenuous situation of her tiny shorts, Mackenzie had made it over halfway through the test. She only had one question left to answer and it required an essay. Giving herself a moment of reprieve from the stressful midterm, Mackenzie took a deep calming breath. It turned out to be a bit too deep of a breath, however. Her expanded chest proved to be too much extra strain for the lone remaining shoulder strap. It snapped free and whipped away from Mackenzie's collarbone, just like its twin had earlier.

Mackenzie both heard the thread snapping and felt her right breast sag ever so slightly lower. She didn't need to look down to know what had just happened. Her tank top had officially been reduced to a tube top! Now feeling more stressed than before, Mackenzie hastily began writing her essay. She wrote the first relevant things that came to mind, no longer worrying about making her response sufficiently detailed and thought out.

She'd just finished her first paragraph when she thought she heard something. Mackenzie paused, listening for the sound again. The barely audible noise happened again, and this time Mackenzie recognized it. It was a sound she'd grown far too familiar with. The sound of tearing fabric.

The redhead anxiously glanced down at her chest, her eyes scanning the pink garment for any sign of a tear. She didn't see one, but heard the sound again. This time her ears could pinpoint it. It was coming from behind her. Nervously, Mackenzie tentatively moved one her hands behind her back. She felt along the fabric, hoping she wouldn't find anything. But in the center of her back she felt her own smooth skin between two parted edges of cloth. The tube top was ripping. The borrowed shirt had been pretty small to begin with, only being about six inches tall in the back. But now it was down to about four!

Even as Mackenzie's fingers rested there, the top ripped further again. Adrenaline coursed through her veins as the redhead began frantically writing. There was still about thirty minutes left for the students to finish the test, but Mackenzie was finding herself with a much shorter deadline. She'd be lucky if the top lasted two minutes!

Another soft tearing sound prompted her to feel for the rip again. It had barely two inches left holding itself together. It could burst apart at any moment!

Mackenzie couldn't afford to waste any more time. She'd just have to hope what she'd written would be enough for a decent grade. Mackenzie rose to her feet as quickly as she could, already focusing on making the short walk to the professor's desk to hand in her exam. But, as she did so, a loud SHRIIIIIIP sound echoed throughout the nearly silent room. Her poor shorts had been snagged far too securely by the seat, and the overtaxed garment had already been near its limit to begin with. The seams had burst apart, allowing Mackenzie to smoothly and effortlessly pull herself out of the shorts entirely.

Thanks to her rushing, Mackenzie had actually managed to be the first person done with the test. But this came back to bite her in the curvaceous ass since every single student was still in the large room. Almost in unison, nearly two hundred heads looked up and turned towards the source of the noise. And every single pair of eyes instantly locked onto the lovely sight of Mackenzie's bare ass.

Mackenzie stood there in shock for a moment, desperately hoping she hadn't felt what she thought she'd just felt. But a quick glance down at herself proved she had felt correctly. She was looking at an uninterrupted view of her pale skin from her ribs down to her socks. Mackenzie was standing bottomless in front of the entire class.

Fueled by desperation, Mackenzie whirled back to face her seat and the shorts stuck to it. She began frantically trying to yank the jeans free, not fully realizing that she was treating everyone to an unobstructed view of her bare pussy. Murmurs, gasps, and giggles rang out through the crowded auditorium-like room while the bottomless redhead struggled with the trapped fabric. But despite her valiant efforts to free half her wardrobe, Mackenzie only managed to rip it further to shreds with her haphazard yanks and tugs. All she got for her efforts were a few flimsy strips of denim, totally incapable of providing any sort of cover.

Well, that's not entirely true. For her efforts, she was also rewarded with a much softer ripping sound. She had pushed the struggling top beyond its limits, and the tear had worked itself all the way through the garment. As if eager to be free, the tube top exploded off Mackenzie's chest and flew into the second row of seats. Her beautiful breasts bounced into view for all to see. That left her, for the second time that day, wearing nothing but a pair of socks and a pair of shoes. Mackenzie was naked in front of her entire class once again!
