Slave to a man part 1

I had always thought I might be gay, at least bi anyway. Sure, I had girlfriends, but it just wasn’t the same as the feeling of sex with a guy. I was the submissive type too, always looking up bondage and domination on the internet to get myself off.
I’m sixteen, tall, slim build but not skinny. My body was smooth, apart from around my cock, which was quite thick and hairy. My uncut cock is average size, around 7 ½ inches standing to attention. I hadn’t had any experiences with another guy before; just fantasising about friends, which could get very embarrassing in the changing rooms at school. The worst thing was dreaming about my best friend, Billy. He was my age, very similar build, although I was a little taller. His cock seemed the same size as mine, although I had only seen it soft in the showers. Every night I would dream of soaping him up, caressing his balls until his manhood sprung up in front of me. Just thinking about him got me seriously hard. Obviously I had never told him, that would be incredibly awkward and I would probably lose him as a friend.
One evening, I had grown tired of watching videos of guys being humiliated and tortured, so I found a site where people advertise for slave boys. Scrolling down the list, one stood out for me: GUY LOOKING FOR SUBMISSIVE MALES, BE PREPARED FOR HUMILIATION.
