When I was in ****school I worked as a busboy in a club where the bussers and waitstaff wore only their underwear. I started wearing thin nylon panties because they showed off my cock much better than tighty whities. I was a walking hardon, it was very exciting to me to walk around with an obvious boner in front of people.
In the 80s, in my city there was a bar with topless waitresses, I went there several times with my wife, and when she found out they had trouble hiring girls, she offered to do it, and for a couple of months, on Saturdays she worked there, she was very exhibitionist and being in front of so many people in a bar wearing only a thong made her completely horny all the time.
