When I was eleven we had this family friend that used to come over for dinner a lot. When I was younger he would baby sit me. Lots of hugs and I would feel his private area press against my chest (at eleven I came up to the middle of his 6'3' frame).
I had always noticed his crotch area ever since those early days. He had something very much bigger in his pants than my little two inch penis. My little dick would get stiff every time I saw him. There were little butterflies in my stomach. I would see him look at my tiny tent and smile.
Sexual awareness was coming on really strong.
One day we were alone in the house, mom was away somewhere for the weekend and we were about to watch a movie dressed only in our shorts (hot summer evening). When he had taken off his pants I thought I would die. That big thing in his pants was now almost in view, my heart was beating faster. My little dick was so hard it must have grown an inch, there was a stain of precum where my cock tip poked at the cotton fabric of my shorts. The stain got larger when I noticed a similar wetness where the tip of his cock pressed against the fabric. It was growing before my eyes. I started to cum just seeing the outline of his growing cock set me off. It was so pink and fat with a head the size of a plum.
The wet stain on my briefs grew larger with each pulsing. I saw his cock fully erect now pushing out the fly of his boxers. He grunted as big wads of cum shot all over him, the couch, the floor and my legs. He never touched it. It just kept cuming and cuming. The feelings were so intense in me that I was doubled over with its intensity. He became my gentle teacher/lover.
He later showed me how to masturbate and eventually this became mutual masturbation and more. I am happily married with two sons aged eleven and nine. I am trying to be as open about matters sexual with them as were my folks.
