I am 22 and work in a three story building. We have parking facilities in the basement and we use the stairs to get to the first floor where our office is. Lately I noticed a guy standing at the bottom of the stairs close to the railings and peeping up our skirts while we are mounting the stairs. Now I must mention that there are four of us working in the same office and we all wear short skirts, so it is quite possible that every morning he gets a nice glimpse of our panties. The other girls aren't aware of this yet.
The first morning I noticed him I was a little disturbed by his boldness, but later in our office I found myself excited by the idea. The next morning I deliberately wore my red see-through panties and made sure that I was alone when I went up the stairs. When I got to the top I glanced back and found him rubbing his crotch.
This has now been going on for the last three weeks and he hasn't made a move to talk to me or anything else.
Maybe soon one morning I might come without panties?
