Wearing knickers in public - the gym

Yesterday I was feeling naughty and wanted to wear some knickers in public where someone would see them. I grabbed a pair of my gfs knickers from the drawer. Only white knickers with a small lace trim. Nothing particularly eye catching but immediately identifiable as womens underwear at a glance. I put them on before leaving the house. When I arrived at the gym the changing room was quite busy,maybe 10 guys in there. I took my top off first so it wouldn't cover them up. Then I took off my shoes and socks and finally my jeans, exposing my knickers clad ass and cock. I stood with my back to the room so anybody could get a glance who felt like it. I'd planned to slip the knickers straight off afterwards but found myself so turned on by the idea of all these strange men seeing me in just a pair of knickers I found myself getting my other stuff ready just standing there in my knickers, maximising my time. I then slipped them off and carried on getting changed. Normally I lock my things in a locker but today I positioned my knickers on top of my pile of clothes so they could be seen by anybody who opened my locker. I didnt lock it and headed into the gym. I half hoped somebody who'd seen me get changed would steal them, or someone who happened to open my locker whilst looking for an empty one, so I'd know there was at least 1 more knicker pervert in the gym but they were still there when I'd finished my workout. After showering the locker room had 4 or 5 other guys in it including one stood next to me. I emptied my locker onto the bench making sure my knickers were on prominent display. I towelled off and slipped my knickers on first and again made myself busy for a few moments so everyone could see. Pretty sure the 2 guys behind me clocked because they had been talking and suddenly stopped when I pulled my panties on. I then carried on getting dressed and left the gym!
Such a thrill and really addictive. Going to try it again next week, maybe wearing a thing so it's really obvious!
