My first cock encounter

My first cock encounter with another boy was a secondary school. One day I entered a class room early for a lesson and a boy named Kevin was sitting there his face looked very concentrated and he did not notice me. Being fairly new at this school I sat nearby to make friends with him. It was then I noticed he was erecting and masturbating with his cock slightly covered by the desk were he sat. I was so surprised to see this. I only ever wanked in my bedroom alone. He was so self indulged he still did not notice me until after he cum and exhaled out a deep moaning breath. He then turned and smiled and exposed his still erect cock to me. I can't remember what he said exactly but he commented on how much he needed to cum. He then quickly wiped himself and put his cock away. We then had a conversation on masturbating, how often, when and to what fantasies, etc.
The next time I saw his cock was in the swimming baths changing room. I was drying my feet and when I looked up Kev was there with his cock in his hand as stiff as a poker. The other boys by then had left for lunch time. Kev was watching a girl name Sharon who was naked and getting changed in the nearby girls changing room. The door was slightly open. He then came to climax and a dribble of cum oozed out his cock as he moaned and pulled his tummy muscles in tighter. I was also feeling horny with a need to masturbate, especially seeing a nude girl. I never saw one apart from my older sister naked. Kev invited me over to his house that night, He lived about a mile from me. He had a fantastic Scaletrix racing set and we played for a few hours. Then without warning Kev whipped out his dick and said lets wank, I have some porn mags to look at. So I nervously got out my cock and started to get erect. Kev was not as shy as me he liked to flash his cock. We both then decided to strip off and masturbate to the pics in the mags. I cant remember who cum first but we enjoyed wanking together and at later meet ups we spent more time naked, masturbating and wanked each other to completion. He a wonderful big cock. Mine was about average size for our ages as I noted in the boys changing rooms. It was not long before we discovered blowjobs, from other porn mags his older brother had hidden. We couldn't wait to get started on sucking each other off. That was fun too.
