The builder's bitch. Part one of four.

I had just come of age, left home, and finally got a job as a laborer in a good, big construction company. It's what I've always wanted, to be surrounded by strong young people. The team was very well structured and the work well organized. All workers wore uniforms and safety equipment. However, only one was treated differently. He worked almost naked, barefoot, wearing only baggy, dirty shorts. The strangest thing is that he wore a collar with a chain, as if he were an animal. Soon we exchanged curious and intimate looks.
