About two months ago my father and my two brothers and I went to visit family in Vancouver. We stayed with my father's cousin Aaron. Aaron has a moderate sized house. Our family stayed in the two rooms he has in the basement. My two older brothers shared the one to the left and my father and I shared a bed in the one to the right. Since we'd been on vacation I hadn't had the chance to masturbate, but it all changed on the fourth night.
It was around six am that I heard noises in our room. It was the sound of blankets shuffling up and down and up and down. After that I started to hear heavy breathing, and that is when I realized that my father was masturbating right next to me. I instantly got a hard on and was wondering if I should just start masturbating right then. I had a better idea though. I decided that I would roll over and steal more of the blanket to reveal what my father was doing. I did so, immediately looked over and saw my father's six inch dick with his briefs at his ankles.
'I guess you've caught me,' he said, 'Since your up, do you want to join in?' 'Sure.' I said.
I started to strip out of my boxers and shirt and revealed a four and three quarter inch cock to my father. I know I'm not the average size, but I still love stroking it. I quickly reached for my father's dick rubbing it up and down. He then reached over, rubbed my balls and commented on the thick amount of black pubic hair I had. I started to rub his dick harder and harder and he did the same to me. He started to breathe a lot heavier, moan louder and louder, and then yelped words like 'HARDER!'. I couldn't take it anymore. I stroked his hard meat as fast as I could. He then let out a vibrating yell and exploded over himself and on to his nice long pubic hairs. He then turned over to finish me off. We never talked about it after that and haven't done anything since, but I'm still hoping for a repeat of that night.
