I remember one of the few mutual jacking sessions I have had was with my step-cousin Tony. I had always been attracted to him and his long wavy hair. We were both much the same build, about 5' 9" and around 160 pounds. At 50 years of age, I was fifteen years older, and was sort of a father figure to him, although he was a little hairier.
Tony was living with me and my wife, renting a room from us until he could afford to move out and get a place of his own. With such close quarters, I had many opportunities to see him in his bikini underwear, and with his long hair and beautiful tanned body, I had become sexually aroused on more than one occasion.
One day i was feeling particularly aroused as I stepped out of the shower. I wrapped a towel around my waist and walked to the living room. As I looked up, Tony was standing at the top of the stairs, I acted as if I did not see him and let my towel drop, giving him a view of my semi hard dick. I picked up the towel and began drying my hair, continuing as if he were not there.
One day he asked me to come up to his room to help him with an issue with his PC. I went up and solved the problem quickly. I then brought up his browser history and brought up some porn he had been viewing.
