How My Cock Fetish Started.

My cock fetish started very early in my teens. Most weekends a friend and I would go to my Grand Parents place and work in the shed on our bikes, hidden in the shed was a stack of porn mags we'd collected. We would often sit and look at the pictures and read the stories, reading the bits of the stories that turned us on out loud to each other.
We had been doing this for several months and for those months I'd sat opposite my mate sneaking glances at his hard cock in his pants and the spot of precum that would be leaking through his pants from the end of his hard cock. I'd decided I wanted to see his cock instead of just the hard outline, so I decided I would take my cock out of my pants and actually masturbate in front of him and see what he did the next time we went to the shed.
We sat opposite each other as always and as he started to read out loud I unzipped my pants and took my near hairless cock out and started to play with it, He looked startled and moved about a bit but moments later took his cock out too and started to play with himself. We watched each other in awe as we pulled our cocks and then the cum started flying. We giggled like idiots as we noticed we'd hit each other with our cum.
This went on for several weeks, but now I want to touch him. I devised a plan. The next time we sitting reading I asked him to get me another mag as they were just behind him. He stood with his pants around his ankles and as he lent forward to pass me the magazine I pulled him off his feet and onto the blanket we sat on. He was still swearing as I rolled him onto his back and gently grabbed his cock, I started pulling it just as I would my own, his hard cock felt so nice in my hand. He didn't put much of a fight, seemed to be enjoying me pulling his cock.
In some of the articles we'd read to each other they'd talked about giving head, so I thought I've gone this far so I'll give it a go. I lent forward and took the head of his cock into my mouth and started sucking on it. He protested at first but within a minute he cock started to twitch and he flooded my mouth with his cum. Not knowing what had happened I started to swallow and got most of his cum down my throat, as I sat up the remaining ran out of my mouth and down my chin, it was an odd taste as I recall but not unpleasant and something I could have gotten use too.
After we settled down he asked if he could have a go, so I stood and approached his mouth with my cock, he took it into his mouth and started to move his mouth up and down my shaft sucking as he went. I lasted as long as I could then I unloaded into his mouth. he swallowed some but spat probably half it out onto the shed floor.
When we got ourselves organised we packed up and left. I think we realised at that stage we crossed a line and unfortunately we never went to the shed again. Looking back I really should have asked him to come back because as I said I could have gotten the taste for cum.
I haven't sucked a cock since and have wanted to ask several guys what if........
