Watched a guy finish with my underwear

Last week I met up with a guy I had been chatting with a bit, who’s kink was to make himself cm from my used panties. So I did my usual routine, which consisted of running errands, grocery shopping, going to the gym etc. And then met up with him in his car at a random cvs and took them off in front of him (wearing a skirt so easy access) and he proceeded to lick them, smell them, and wrap it around himself and call him names while he pleasured himself and I did the same to myself next to him until we both came, and it was honestly super hot. He payed me to keep my undies and I left!
