The hem of her towel was snagged on the tree

[Originally by SpiralFelix]

Thanks to the rain, Mackenzie didn't quite hear the soft tearing sound as the bottom corner of her towel remained behind on the rough tree bark. The missing chunk exposed an extra inch or so of her right thigh. It wasn't much more considering how much of her bare legs were already visible, but it had begun a tear in the towel that continued up at an angle.

As Mackenzie took a few steps forward, the bottom of the towel began tearing away from Mackenzie's body. The split in the fabric seemed to move upwards as it creeped across the towel. An inch of towel at the corner became three inches of towel as the split circled around to the right edge of her ass. And that increased to six inches by the time it had reached her left hip. Mackenzie's towel barely covered her ass anymore.

Finally noticing the sensation of the cloth leaving her body, Mackenzie began to look behind her, but hit another muddy spot and began slipping forward. As she crashed to the ground, there was a loud ripping noise and the towel finished it's split.

Mackenzie quickly got to her feet and muttered "Oh no..." as she realized her towel had been basically ripped in half along the diagonal. What was once a long rectangle to wrap around one's body was now a long triangle to wrap around one's body. The right side Mackenzie held in front of her still covered from her breasts to her thighs. But the left side was the opposite. She had just enough fabric to cover her left breast.

Mackenzie now began jogging towards the door, holding her towel together at the top with her left hand and pulling the bottom in front of her crotch with her right. She garnered more cheers and whistles from the few remaining onlookers, making her blush even more furiously. She kept her head down as she walked past the fireman holding the door open. He chuckled appreciatively as Mackenzie's nearly bare ass jiggled past.

Glad to finally be out of the rain, Mackenzie hurried back to her floor. The halls were still bustling with people and Mackenzie was still getting plenty of attention. Rounding the corner, the bathroom from earlier came back into view and Mackenzie hustled through the door.

The lights were back on, thankfully, and Mackenzie quickly moved into the same stall as before. She turned on the warm water and began washing the mud and dirt from her body. It felt heavenly compared to the freezing downpour. And the privacy felt similarly wonderful compared to the exposure she had just endured.

A few more voices were entering the bathroom now as other girls were beginning their days as well. Mackenzie finished up and reached for her towel.

"Oh, right." She said upon remembering the current state of her towel. She looked around the stall, but her pajamas were nowhere to be seen. What the heck! Did someone take them? They had, after all, been left unattended for the past fifteen minutes or so, even if the building was unoccupied for most of that time. Just perfect...

Mackenzie resigned herself to her towel once again, wrapping it around her body again. After all, it did offer some coverage for her. But, as she reached the door, Mackenzie realized she needed a free hand to use the knob. Cursing to herself, she kept her towel together up top and let the bottom swing away from her womanhood slightly.

Exiting the bathroom quickly, Mackenzie booked it down the hallway towards her room. Then, the thin slippery towel end fell from her hand and Mackenzie let out a small noise of surprise. It swung down, leaving Mackenzie's entire backside bared for all to see.

With her room in sight, Mackenzie clutched the towel in front of her body and just plowed ahead. There were less people out now, and Mackenzie only passed two girls on her way. Both offered raised eyebrows and long stares but said nothing to her.

Mackenzie burst into her room and quickly shut the door behind her. She let out a long sigh as she finally allowed herself to relax and catch her breath. Then she noticed she had let the towel fall completely in the act of closing the door.

That was when Mackenzie realized that...
