I did once in Chelsea Park in England. I was just so horny in that moment ... I was wearing a skirt, cause I was a lot more femme at the time, so I just lifted up my skirt, I was wearing knee high socks as well, so there wasnt really anything obstructing me ... I kind of just went under my skirt, under my underwear. I like to move my underwear to the side cause it feels a lot more naughty when you don't take your clothes off. And theres something about going home with soaked underwear
