Public oral sex?
I have found myself in the woods in a rest area, on my knees with one guy's cock in my mouth and several others watching and waiting to be next.
So much excitement. In a public rest room sitting in a booth with no door with a guy standing in front of me, his pants on the around his ankles and his hard penis in my mouth while a couple of other guys at the urinals look on and jack themselves.
Once in a restroom in a big department store, a guy is in front of me on his knees sucking me for all he is worth while a big hunky guy has me in his arms, running his tongue down my throat and another guy is playing with my ass. Another time in another department store, a guy is kneeling in front of me sucking my cock while another guy is eating my ass at the same time. What a climax that was. I am always turned on by being watched.
