This one time when I was at an ABS I had just got there and was hunting a booth to go in to watch a couple of short movies. When this young good looking girl came around the corner and ask if I wanted a BJ. She pointed me to a booth and then told me she would go into the one next door. As I opened the door to my booth I could see part of her face looking at me through a 4 inches hole in the wall. She told me to stick my cock through it and she would suck it for me. I did as I was told and after a few minutes of sucking she stopped and then asked if I wanted to fuck her ass. I said sure why not and then she pushed a tube of lube through the hole telling me to smear some on my cock. After I finished squirting and rubbing lube all over my cock. I looked down at the hole and could see her butthole already pressed up against the wall. I started fucking her and it didn't take more than five or six minutes before I was ready to cum. I yelled out that I was going to cum in her ass when suddenly the door to my booth opened up and the girl that I was supposedly fucking was standing there in front of me. I had just cum in someone's ass but it wasn't her. I quickly jumped up without even pulling my pants up and pushed her out of the way to see who was in the booth. There on their hands and knees with their ass still pushed up against the wall was her boyfriend. When it comes to gloryholes you never know who's on the other side of the wall.
