Any type of setting, whether it be someone you met at an event, public transport (heard a great plane story once), etc….
If you provide a pic of yourself or the act even better, but obviously not required.
To start – One time I was on a train from Manhattan out to CT, last one of the night. There was a couple sitting in front of me and to the side, but otherwise the train was totally empty. Some girl comes back and sits right next to me, which was kind of weird since the train car was empty. We exchanged ‘hellos,’ but that’s it. Next thing I know she’s putting her hand on my thigh, leans over, and says “you want some train head?” I was pretty shocked, but of course went with it. When it was over, I couldn’t stop but worry that she was going to try to ask me for money or something, but she never did.
