Christmas shopping blowjob

I was Christmas shopping at Valley Hills mall in Hickory, NC looking for a few last minute presents. I was in JC Penney's and needed to pee. They have a nice large bathroom on the lower level so I decided to head that way. I was standing at a urinal emptying my bladder when a nice looking man walked in and went to the urinal beside me. He was probably in his sixties with gray hair and looked to be in good physical shape for his age. He unzipped his pants and pulled out a nice looking cock. Apparently he saw me staring at it and he began to stroke it. It wasn't long before he had a full erection. I looked up and saw him smiling as he turned toward me. He nodded to me and I knew he wanted a blowjob. I knew someone could walk in on us, but looking at his beautiful hard cock I didn't care. The possibility that someone could have caught us made it more exciting. I got down on my knees, put my hand around his cock and starting sucking and stroking him with a purpose. Usually I ask the man to let me know when he is going to cum so I can pull his cock out of my mouth and take his cum load to my face, but this encounter happened so quickly I didn't think to mention it to him. After a few minutes he put his hand on the back of my head and pushed his cock deeper into my mouth almost making me gag. All of a sudden I felt hot, thick cum hitting the back of my throat. His cock was so deep in my mouth and he had such a firm hold on my head I knew my only option was to swallow his cum. He continued cumming and I continued swallowing until he released his grip. He pulled out and zipped up and left the bathroom. I walked out a few minutes later and saw him standing with a nice looking woman in the home furnishing department. As I walked by them, he looked at me and winked. I smiled back at him, still able to taste the residue of his cum in my mouth.
