Quickest and Busiest.

Mandy could tell you a dozen ways to get to her own house from the college but knew only one to Karen's which was much closer.

"This way come on" Mandy again dragged Karen by one arm the other girl blushing crimson and keenly aware of her body under the towel, her only covering.

The trek was slow and humiliating for Karen whose bare feet found every pebble and rock in the road if she didn't stare down and watch her footing. As she was jostled and pushed around in the lunchtime commute.

Several blocks of this jostling and the iron clad grip she had on her towel proved to be her undoing. Soon without her realizing it the knot itself had come untucked and it was only the **** of her grip holding the towel in place.

They continued out of the business district downtown area, skyscrapers transitioning shopping centers and corner stores.

The wind began to pick up as the sky let loose a gentle spring shower.

Gentle as it was it wasn't long before the girls were soaked from head to foot. Mandy's thin T-shirt and braless state leading to her top clinging to her C-cup breasts.

Both girls were blushing madly as they half jogged across a highway overpass. Which is when the inevitable happened.
The girls would argue for years over who's footing gave first but the fact of the matter was a strong gust of wind sent them both slipping and sliding for several feet hands flew out for balance and the towel fell limply to the ground. Mandy took a knee to help regain her balance. Sending Karen rolling over her and landing in the grass of the medium. Mandy looked up just in time to see the towel flutter over the edge of the overpass. She watched as it fell to the highway below and was quickly run over by a half dozen cars in the lunch time traffic below.

Karen for her part was completely leaving her crotch unguarded gripping an imaginary towel that was no longer there.

Mandy took stock of their states. She herself was soaked to the soak her Jean shorts clinging uncomfortably to her body while her top left little to the imagination. Meanwhile Karen was once more completely naked in public.
