Ive become a big fan of sessions with natural light. Spaces with big windows. Most Dungeons are warehouses or basements so tough to find.

I would love to do a session in a gym. I think you could find all sorts of kink uses for the workout equipment.

Id also love to do a wrestling session in an actual ring

Not a session per se but the women/dominatrix i was dating once punched me in the balls without warning going through the starbucks drive through. It was a hot semi public moment as i tried to keep it together and get our coffee. The sex after that was top tier.
