I [19F] touched myself in my car in a grocery store parking lot imagining about a recent incident that I heard

I [19F] posted a few days ago about imagining about hearing a couple go at it while at work (was a little slow day). I had to run some errands after and I was pent up all day and since it was pretty dark, I touched myself a bit while in a random parking lot which was pretty scary but nervous. I did something similar in May (posted about it) but this time felt kinkier as I knew what I was getting into.
