While the following story is mostly true, I DO NOT recommend this as a common practice!
I have a confession, I really like to have a cock in my mouth!
One of my favorite experiences happened shortly after my first time. I was cruising through a porn shop video arcade area, and found a door to a booth slightly open. I looked in, and saw an older man, his pants and boxers down around his ankles, and his cock in his hand. As I looked up, I saw he had noticed me, and with his free hand he motioned me to step in. As I did, I closed and locked the door to the booth behind me.
"If you want to suck me, feel free, or you can watch me jerk off, your choice," he said quietly.
I smiled, and then looked at his cock. It was, without question, the most perfect looking specimen of manhood I had ever seen. He was probably a solid seven inches in length, and his girth was impressive. Circumcised, the crown of his cock was large, glistening with his precum. I knew I had to have it in my mouth!
