I was 13 neighbor kid 13 also, messing around in his garage. One thing lead to another. Started comparing cocks and then he started touching and milking my cock. He asked me to suck his and I did. I felt his cock get hard in my mouth. Neither of us came this time, but another time we went at it again and he gave me a handjob and I shot a load all over and I gave him a blow job and he came all over my face. Fun times. We messed around off and on for a couple of years.
