I don't know if I should post this under upskirt story or exposing wife

but it's upskirt-related.
Happened couple days ago when we went to community library. My wife would like to get some books there. Due to my request, she's wearing a short pleated skirt showing her nice pair of legs.
There's this moveable stair with wheel for people to get book at the top shelf. I found there's a guy next to one and did his reading. I talked to my wife suggested maybe she could go up the stair pretending looking for some books there and see if the guy would look.
She then did what I asked, and I stayed away like 2 isles and checked out the guy through book shelves. He first gave a quick glance at her and moved a step away. After my wife stepped to the top that stair, he started looking up, like secretly peeking every 2-4 seconds.
I knew she's wearing one of my loved grey plain narrow panties. With her wide opened pleated skirt and the guy's position. I could imagine how a wonderful view he had on my wife's butt cheeks.
She then got down after like 5 minutes. He first pretended he's focusing on the book, but then he tried to talk to her. Later I asked her, she said he tried to get her number
I don't know if this fits in this thread. If yes, I have tons of this type story to share.
