One other time I was getting a HJ in a curtained booth, which wasn't too unusual. Right when I was getting close another dancer and customer pulled back the curtain because they thought it was empty.
I was standing up with my back to the curtain and my girl was sitting on the bench in front of me. I turned quickly but she just kept pumping away. The couple at the curtain just stood there for some reason with their mouths open - maybe they were just surprised. I thnk I unintentionally gave them a better view by turning.
Anyway, I was too close to stop and I figured to hell with it and just unloaded on her tits. It was one of the best HJ endings I ever had. She was stroking hard with one hand and squeezing my balls with the other.
The couple behind me just broke out laughing and clapped a few times, then closed the curtain and went into the next booth. I'm not much of an exhibitionist, but that was pretty memorable. I could still hear them giggling when I passed by them on the way out.
