Go for it!
I always had this fantasy of jacking my boxing coach's cock. He was 30 and a former pro-boxer. I got my chance when he had to massage me because I was so 'tight', and I wasn't working out too good. He gave me the best massage of my life and I fondled his cock and balls. He got a hardon naturally and I already had one. We took our time feeling each other up and we gave each other the most powerful orgasms a guy could get. After the first time we became regular jack buddies until I graduated.
