Hey guys, I'm(M) relatively inexperienced in the art of being a dom, and have had almost all of my dominant experiences with my primary partner(F).We're not in a d/s relationship, it's more something we experiment and play with every once in a while. We also dabble in some nonmonogamy.

Last night, we were at a sex party of about 70 people. It was a great party. At one point in the night we found our way to the kink room where there was a restraint/mount thing for spanking. My partner got on and we we started playing. Nothing too crazy, mostly flogging and some sensory play, and something I'd never seen before called a vampire glove (which we both loved). Pretty quickly we gained a bit of an audience. We both love exhibitionism and we found it very hot. My girlfriend reached the point where she'd had enough and got up. One of the other girls watching the show jumped up and asked if she could be next. I got the look of approval from my girl and I said sure hop on. I kinda felt like I was put on the spot, but was also feeling pretty powerful and in my dom space. I asked her what her name was and what her pain tolerance was. She told me her name and said she had a high pain tolerance, and we got right to it. I guess I felt some pressure from her and the crowd to keep the show going. It went well and she loved it, but in hindsight I feel like maybe there is way more we should have talked about before we started playing. Like boundaries, do's and don'ts, aftercare...

So after that lengthy story, my question to you experienced doms is...

When finding yourself in a situation like that, some kind of party environment, what are some non negotiable questions you bring up before playing with a new partner? I'm more comfortable having a full on sit down conversation to get it all out on the table, but in a party like that it would have been difficult when all eyes were on us. I guess I'm looking for a kind of blueprint to speed through that process and hit the essential bullet points before engaging.
