Through the park

"Let's cut through the park." Amy said, "It'll get you home quicker."

Mackenzie agreed and the group made their way onto the path bisecting the park. The gown-clad redhead was still warily keeping her hands on her only form of cover. A strong gust of wind could appear at any moment.

On such a beautiful day, the park was full of people. All around them were people playing, picnicking, or just enjoying the weather. But the crowds made Mackenzie nervous. The redhead still felt quite ****, given that one thin black sheet was all that was separating her from public nudity.

Mackenzie's nervous thoughts were interrupted by a teenage boy shouting "Mark, look out!" A different boy was looking up in the sky at a spinning frisbee and running to catch it. The oblivious teenager bumped right into Mackenzie, sending her careening into a thick bush beside the path.

"Oh crap! I'm so sorry, are you okay?" the boy asked nervously.

"Ow... yeah I'm alright." Mackenzie muttered before standing back up. "No harm done." she said, swearing she heard some faint zipping noise.

Instantly, the expression on the boy's face, along with those on Mackenzie's three friends' faces, all changed to stunned. One of the bush's branches had snaked its way into the hole of the gown's zipper. And, as Mackenzie rose, it unzipped her gown all the way down. And, unfortunately for Mackenzie, the zipper track ran all the way down to her thighs.

"Kenz!" Jess said, seemingly awestruck, "Your zipper!"

Mackenzie looked down at her gown, and was shocked to see a strip of pale skin running from her neck, between her breasts, and all the way down to her shaved pussy, which was completely on display.

"Noo!!" she shrieked, grabbing the zipper and yanking it upward. But with her frantic strength, Mackenzie instead ripped the zipper off its track entirely. "Noo!!!" she cried again before hastily trying to hold the garment closed with her hands. Mackenzie had moderate success. She was able to clamp the fabric closed over her pussy and chest, but this still left small windows of flesh in between her two hands.

"S-sorry!" the boy said again before running off, not believing his good luck.

Mackenzie stepped out of the bush, awkwardly clutching her gown, and eagerly began walking again. "C'mon." she said to her friends. "The sooner we get back to my place the better."
