This was a few years back at my first Burning Man where I ran around with my ex-gf for a week just trying to experience everything I could. We'd looked over the schedule at the beginning of the week and decided to attend an oral sex class one afternoon. We showed up to a big geodesic dome filled with nervous couples waiting for the instructor and an outgoing woman with a British accent was making brash jokes and passing around a giant container of margaritas. We took a swig and passed it along to the couple next to us… eventually the strong sex-positive instructor announced that we were ready to start the class. She was a therapist, activist, and researcher who had spent a lot of time handling groups like this and quickly put us at ease and ran through advice, techniques, and other information interspersed with anecdotes from her days on the sets of porn shoots.
We all half-forgot what was coming, but she eventually said "ok, now time for the hands on part of the workshop…" Everyone was suddenly nervous again but it was hard not to be at least a little turned on considering the topic of the day. The couple to our left was a tall lanky white guy with short curly hair and a sexy looking gal with egyptian style eye makeup and a high pitched airy voice. The couple on our right was a bit farther away and didn't catch my attention nearly as much… The women were up first and I kissed my girl while working her bikini bottoms down past her knees. She shifted her back onto one of the pillows that were scattered on the floor and settled down between her legs and got to work. She was very responsive and vocal, but it was hard to tell if anyone else noticed… it all blended in with the sounds of sex all around us. I remember looking over at the egyptian eye girl when she hit a very high pitched gasp and we both had a moment of shock when our eyes met and we seemed to realize where we were and what was going on. It only lasted for a split second as her guy made her throw her head back and try to catch her breath again. Things got louder around us then settled back down as couples collapsed post-orgasm. The British woman was one of the last to finish and she had a very identifiable frantic scream when she came.
Then the instructor announced the switch and it was my turn. I was nervous again. I'd never been naked in anything close to public before, but I didn't get a chance to think about it. My girl had me under her and my pants off before any of the other couples in view. They followed her lead but struggled to keep up with her energetic style. She caught their attention when she choked herself on me intentionally and had a coughing fit but she immediately got back to work. Egyptian eye girl had a much gentler thing going on, but he grabbed her hair and pulled her head down tightly when he came. I followed not soon after and we cleaned up as other couples wound things down. We all thanked the instructor and filed back out into the desert, ready to see what else we could find before the sun set and the real parties started.
