Male to male massage

I normally have a massage with asian ladies but this time saw an ad in local paper "adult services" for a male/male massage. I didn't know whether this was a straight massage or a "sensual" massage but decided to try anyway.
The masseuse was a fellow about 75 yrs old , tall and thin. He requested I strip and lay on the table and offered me the option of a towel (I declined as I am an exhibitionist by nature and love being nude in company). He then said in that case would I like him to strip and do the massage naked and I accepted. He then stripped and I was shocked to see the size of his cock. It was 6-7 inches flaccid and was quite thick and circumcised.
The massage was very extensive and covered every extremity and took over an hour. At one stage, while doing my lower back, he knelt on the table with one knee between my legs and thrust back and forward while working my lower back. Each thrust caused his cock to slap my upper thigh most obviously.
He finished the massage and asked me to turn over and then offered to give me a happy ending. I agreed ( I like anybody playing with my cock) and he did a good job and just before I came I reached down between us and grabbed his cock. I could feel it swelling as I shot my load. Sadly I didn't see it erect as it would have been most impressive. I had another couple of massages with him, still missing out on seeing his erection, and then he moved away and stopped advertising in the local paper so I couldn't find him again
