We were on a trip to Germany a few years ago. One day, we had this local guide named Sandra, a tall blonde 40-some woman, who wore a grey checkered cotton shirt and black ankle boots. Nothing more than that, so it seemed: her shirt barely covered her crotch and her entire long legs were visible.

Of course, she must have been wearing a small pair of shorts underneath, was my first thought, but I quickly noticed that Sandra was being a bit too careful with every move she made.
When we had to climb the stairs to the city hall, I tried to walk behind her, but she would let everyone else go first and then she followed.

During the tour she was also very careful not to lift her arm too high, and she would regularly run her hand across the hem of her shirt, just to check everything was still in place.

This extreme caution made me absolutely want to know what was underneath this shirt of her, maybe nothing at all, and she was wearing this attire for the thrill, who knew?

When we left the building, she definitely wanted to be the first to go down the stairs.

At lunch time, she had to slide onto a bench under a table, and of course I kept a close eye on her.

Sandra went to sit down with her legs crossed and had her hand pressed into her lap.
After lunch, she got out of there in the same awkward way, making sure the hem of her shirt didn't stay up in the back as she stood up.

In the afternoon we had to walk walk through a street with tall buildings, where it got pretty windy. Our guide now had to hold down the hem of her shirt, still not giving anything away of what she was wearing underneath...

We entered one of the buildings and could take the elevator to the rooftop, where we had a panoramic view over the city.
Quite surprisingly, there was hardly any wind up there, and Sandra walked around with us and explained what could be seen.

After having done the round, we could look around on our own.

One woman was looking down and asked a question of something she saw. Whilst chatting with the woman, Sandra walked to on the wall in front of the safety glass to get a better view.

She leaned forward and put her hands on the wall, and suddenly the secret she managed to keep hidden all day long was revealed: the hem of her shirt lifted, and her ass appeared, wrapped in light blue bikini style panties...

As she stood there leaning on the low wall, I (and probably others as well) could effortlessly enjoy the best view of Sandra leaning forward, with her round butt in the air and her baby blue panties in plain sight...

After a minute or so, Sandra stood up straight again, but her cotton shirt didn't come all the way down at once. She now put one hand behind her back as to do her usual tug down, and as soon as she felt her lower butt cheek and/or undies sticking out, she grabbed the back of her shirt with both hands and gave a good tug down. She turned away from the wall, and looked around to see if anyone had seen her butt. She seemed startled!

As we continued down the windy street, Sandra was convulsively holding down her shirt with both hands, in the front and in the back.

During our pause in a local café, Sandra was no where to be seen.
As she came to pick us up, she had apparently gone shopping: she was carrying a bag of a local department store and had finished off her outfit with a long denim skirt, which of course meant we wouldn't get a view of her undies anymore...
