Never seen or heard of a gloryhole. But did a lot of mutual jacking with my buddies. I was 15 on my way home from school and went in a department store looking around in the music section. I started feeling like I had to go to the mens room. Two doors to enter, the first room had sinks on one side and urinals on the other. The second room in back had the stalls.
I went in the back, sinks on the left with lights overhead that were on and the stalls set in on the right and the lights above were out. I rushed in the first stall unbuckled my pants sat down and found it was just a false alarm. Looking around I saw a round hole in the wall to my right and a man in his 40's sitting there legs closed with his hand between his legs. Not knowing if I could see him, he could see me also. I sat there like I was spying on him seeing if he was going to jerk on his cock. My cock got rock hard watching, all of a sudden his hand started moving back and forth a little.
Then it hit me he could also see me so I followed his every move and did the same. Next thing when he saw me do that his legs opened showing me his big hanging balls and bouncing thick big prick. I just spread wide leaned all the way back and started rubbing and jerking on my cock. He put his eye up to the hole which got me nervous having him see my face, he wanted to blow me. I said I justed wanted to jerk off with him. He was like ya get up, show me that cock. He got up to stand in front of the hole and I did the same reaching in to feel and jerk on his cock. The first older cock I jerked but not off and the first older guy to jerk me. But I let him watch me finish myself off and watched him. Never been so horned up like that in my life. Well that was my first time, but it wasn't my last. It wasn't always just to jerk off. He was also my first for that.
