Went to a first time face to face public meeting with a pro/for hire d********* who is willing to take me on as a submissive client. I have gone to dominatrices a few times before so i expected to be made to squirm or be embarassed to some small degree in public. It was at a bar at her direction. Most of the conversation was her asking me “what about….” this or that, if I had experienced this or that, what are my curiosities and things willing to be explored. She was not deliberately loud but if someone was close, and the bartender, could hear and i was redfaced a lot. She only had a couple of drinks but was ordering them constantly for me amd telling me to drink constantly. When she was done asking her questions she suggested we go have a trial run session which i was definitely not prepared for. The suggestion caught me off guard and before i could even respond she reached out as we sat at the bar and took a severe pinching grip on one of my n****** out of sight inside my hoodie. I yelped a little but mostly just leaned into it and panted as she kept the grip. Told me I looked as though I was about to tell her no. She kept the pinch grip on my n***** as she instructed me to pay the bartender who looked like he was more than ready for us to leave. She released my n***** so we could walk out and told me to walk her to her car. We got to her trunk and she said i probably should have pissed before we left. Then she slipped her hand into my hoodie again and pinched and twisted my other n***** severely. I gasped and whimpered but still leaned into it and rose on the balls of my feet and gasped again when she told me very sternly to wet myself for her and my bladder complied to my embarassment. She held my n***** until my bladder was empty and my pants and socks and shoes were soaked and then told me not to stand there for the whole world to see that i had pissed myself. She hit her key fob trunk button and told me i was not in shape to drive and i was certainly not sitting in her car soaking wet from p****** myself and told me to get in the trunk. I was unable to refuse her by this time between excitement shock and alcohol. She told me she expected to find me naked and out of the piss soaked clothes when she got to her dungeon and opened the trunk. Her expectation was met.
