Vicious twenty-year-old enjoying his co-worker’s cock.

Video offered by blacks on boys i've only been working in a warehouse for a week and since i was twenty years old i had no experience, i never thought they would hire me. one day taking a couple of boxes to the warehouse one breaks a little and i see that inside it is full of movies. i show them to my partner and he gets horny lost from seeing the cover of one of them. when i turn around he's with his cock out and jerking off. how was it possible that he had a huge cock hidden in his pants without showing anything?
