First experience

I was in the Army for 24 years and first knew I liked cock while getting in group showers and seeing all those other cocks lathering up. It was so difficult not getting hard. Well I was 40 and still never had tried cock until I was at the gym locker room and was walking by a shower with the curtain not pulled. The guy was lathering up his nice cock with a nice hardon. He saw my reaction and looked down at it with an invitation. I looked around and was nobody around and I walked over and touched it, stroked it a few times for him. I was a bit nervous in a public place but he pulled the curtain and pushed me to my knees and grabbed my head forcing his cock in my mouth. I choked a bit but he unloaded a huge load in my mouth and said swallow it bitch. I did my best and he said we need to work on that. My first BJ and he helped me perfect my skills over the next few months.
