[Nerva]

One afternoon I came home from work. After, leaving the bus station I was walking on the side walk to my flat building. In front of me, 150 meters away, a mature lady was walking. I think she was around 45 y.o., 1,65 meters tall, blonde hair. She was dressed with a grey, knee long summer skirt and was carrying a backpack bag on one shoulder. The dress was catched between her back and the bag. Funny thing, the dress was moving up with each step forward of our lady. I increased my speed towards her. The dress moved up revealing her left thigh and a few steps later even her left buttock. The image was very exciting. Unfortunately another lady exiting a bulding told her that she walks with half ass exposed (feminine solidarity) and she released her dress from the catch made by the backpack bag.
She blushed and smilled when he saw me walking 10 meters behind her. I smilled too.
I enthusiastically expect summer because there will be pleanty of opportunities for upskirt situations.
