An experience many of us men have had is on the airplane while traveling. One I remember many times is the flight attendant facing the back of the lane while landing or take off. The gal has to maintain her grip on her legs as the plane takes off. This is tough when every male eye is watching to see if her legs open while on the tarp. I have had a privilege many times being in first class first row to see those nice upskirt shots. Also staying in hotels for flight crews, and enjoy the time with a hot flight attendant while on lay over.
I used to while traveling around the country visit local shopping malls to get some time off from work. I made a point of checking out the ladies dressing rooms for curtains open, ladies unaware they left something unclosed. One time in particular a gal was have her bras measured and I stood there and watched. I sat on a chair, opened my trench coat, unzipped my pants and let my cock fall out. The gal getting measured saw me looked down at my cock and just smiled. She was turned on by the incident since she was unable to move.
My girlfriend purposely wore skirts with no panties and stockings and tight little short shirts and I would play with her little tight wet pussy with people in the room with us and I would feel her squeeze my fingers when I got her to cum a satisfying orgasm as people are talking to her and she was dripping wet and shaking her plump round booty and thighs squeezing my hands under the table
