Like most young teen boys I spent a good amount of my time thinking about girls and ways to fool around with them. One day after school somehow my classmate Julie and I ended up in her father's shed behind her house. One thing led to another and soon we were making-out.
There was some light petting which led me to take Julie's hand and place it on my crotch. I soon had a 'boner' as I once refered to an erection and reached down and dropped my pants for her. Julie's first reaction was to pull away from me. I found myself just sitting there, hard as a rock, trying to talk her into using her hand on me.
Teasing me, Julie refused to jerk me off. She told me 'why don't you just do it yourself' and giggled. I smiled at her and told her that I needed something sexy to look at in order to 'get off'. To my surprise she began to undress for me. While Julie stripped for me I masturbated for her. Trying my best not to cum until she was naked I stopped my hand and just watched her.
She looked at me and said 'if you stop, I stop'. That said I began stroking myself again. Then it happened. I began to cum. Seeing Julie standing there wearing only her bra and panties put me over the edge. My cum started squirting everywhere, some even landed on Julie's lower leg. She 'freaked out' when she felt the sticky liquid running down her leg. I couldn't believe how she over-reacted. She dressed quickly and left me there covered in my own mess.
