I was getting in a workout at my regular gym, and it was a bit warmer than usual so I was sweating a LOT more compared to usually. I was wearing a sports bra biker shorts, and per usual, I could notice a lot of the older guys perving on me and catching glances at me when they thought I couldn't notice. Towards the end of my workout, a guy walked up to me and started talkin about one of the workouts I did. He seemed genuinely curious about it and like a nice guy, so it came as a complete fucking surprise when he asked to buy my sweaty shorts and panties right then and there. I was at first kinda weirded out, but he offered a lotta money for just those two pieces of clothing and I was kinda extremely whorish after a whole ass workout. I told him that I wouldn't have anything to wear underneath as I was leaving, so he offered to grab them right by my car so I could just drive home. This was a massive red flag for me (random guy following me to my car), but I parked right by a bunch of stalls for a farmer's market there was a security camera mounted in the lot that I always park under cuz im paranoid about thieves lol. We chatted all the way up to the car, I got in, closed the door to not flash the camera, slid off my sweaty shorts and thong, and handed it to him through the window. He most definitely caught a glance at my bush but he thanked me for it, gave me the cash, and went off to his car. I got such a fucking thrill out of doing that and then driving home commando (I even played with myself on the ride), I really hope the situation presents itself again :)
