My first cock belonged to my younger cousin. I still remember the first time I put it in my mouth, I was so young I had never even heard the word "cocksucking". It just seemed natural to want to learn what it would feel like to hold another cock in my mouth.
to dogman504 :I was half that when my much older cousin decided to teach me about men - thank god he did, have loved it ever since! He showed me porn mags too, but his cock was much bigger!
