My Cousin and I

So I've never really told anybody this and I've wondered if it was wrong... When I was younger one night my cousin was staying over. Well we were laying there and I told him I liked to sleep naked, then after some conversation I took my underwear off. He pulled the covers to see if I was really naked and he saw my hard cock. He kind of didn't know what to do, so he took his clothes off and naturally I started playing with myself and he did too. We kept doing that until we came. We only did it that one time and never again.
