I used to steal panties from laundromats. I would bring a basket of easily disposed of clothes if I had to leave quickly (items bought Salvation Army stores) and a novel or magazine and would usually place the clothes in a dryer because that would give me a reason to be sitting near the dryers.
I would watch people come in and when I saw someone I thought was hot, I would wait until she put her clothes into the dryer and if I could, I would then causally stroll over and, open it up and steal a pair of her panties.
The place I usually hung out at near several trendy coffee shops, and close to a university so I would get all sorts of hot young women coming in to drop off their laundry. Most of them would then head out to a coffee shop, and this was before the explosion of social media. Phones, and camera phones were around, but not like today.
I found it so hot to think about the girl I stole her panties from, and would often wear her panties, or jerk off into them all the while thinking up elaborate fantasies, usually involving her as my already broken slave.
DM me if you want to hear about some of the sexier panties I stole.
