I've been meaning to write this for some time and finally plucked up the courage.

I'm bisexual there's no denying that I enjoy sex with women but I also enjoy having sex with men, in fact my first time was with another man.

I was a kid when it first happened, Colin(not his real name) and I had been friends for years, we wnet to the same schools, were in the same clubs and generally hung out together all the time. We were in the Judo team together he and I were equals except when he cheated and he loved to cheat. 

We had seen each other naked loads of times so were comfortable around eacother, one day while walking out of the changing room he pressed up against me rubbing his crotch against my backside. I could feel his erection through the fabric of our clothes he placed one hand around my waist and whispered into my ear I want to fuck you in the ass. I didn't know what to say, he laughed it off but I couldn't forget the feeling of his cock.

A few days later we were doing cross country and I'd stopped to catch my breath, the view was amazing from up here I couod see the entire city, Colin came back to check on me and leant against a tree, it was fairly sheltered, he got this look in his eyes and I could see him beginning to bulge in his shorts. He kissed me and I felt my own erection start. I had thought about what he'd said. We kissed several times tounging and biting our lips, "I want to fuck you in the ass"  I locked eyes with him and ran my hand down his chest and pulled his shorts and boxers dow. I ran my mouth over his toros down to his belly and ran my tongue over his cocks shaft. "okay" was all I said.

With nervous energy I started to stroke his cock feeling its veiny girth, the regular pulse of it. I ran my lips over the tip of it flicking the tip with my tongue and he very nearly came right there and then. I held it until his urge died down and then opened my mouth taking his cocks head into my mouth and then slowly began to suck along the warmth I held my lips over my teeth as I worked his cock. My hands squeezed his rear end while he played with my hair(it was long and had a terrible habit of going curly). "Oh my God that's amazing I really wanna fuck you in the ass".

I pulled his cock out of my mouth, trails of saliva joining us together and running down my chin. He pulled me up and pushed me over a fallen tree stump and pulled my shorts and y fronts off, He pressed the head of his cock against my sphincter and thrust but it wouldn't go in I gasped in pain and reached behand me pulling my buttocks apart. "Slow down, take your time, we need lub or something and you need to push in gently", he hawked a load of phlem onto my butt I couod feel the warm spittle on my sphincter, with my buttocks held open he slowly pushed his head against the puckered portal and pressed into it.

 It hurt like hell and my anus resisted at first but he eventually got the bulbous head inside and it started to feel a lot better, he spat again and then pushed his cock in as far as it would go, he was long and thinish so it went in fairly far. He began to thrust as I held my cheeks apart, the wood pressing into my belly and my own erection rigid, my balls having partially shrunk at his initial efforts started to drop to their usual length. His hands clutched my waist as he began to thrust in and out of me in a regular pattern, with every inward thrust his balls would slap into me with a wet sounding thwak, he leant forward and nibbled on my ears biting my neck and giving me one hell of a hickey. after a couple of minutes I felt his cock start to flex as his breathing became quite rapid and he rutted away in a semi animalistic state. Pre cum was dripping from my own penis by now and the feeling of his cock must has pressed against something as I felt myself shudder just before he did and we nearly came at the same time. As his cock spasmed and jerked inside of me he splashed my bowels with his warm seed and my own cock went rigid and sprayed cum all over the tree stump it flowed out of me and trickled down onto the ground in long strands while his own sperm sloshed around inside. 

As he pulled out I could feel it running down my balls I looked down and watched as it pooled into my own sticky discharge on the ground. We collapsed utterly spent my anus I can't quite describe it a mix of pleasure and pain, a sense of togetherness and now emptiness. "I wanted to do that for ages" I looked at him and said I know "every single time we played together youd would find an excuse to grind yourself on top of me, we should get dressed and get back before we are missed", Colin agreed but said he wanted to do this again sometime. If that's what you want was all I could say.
