When I was in college, I worked at a local retail store as an hourly manager. For awhile, I was in charge of training the new employees. Normally, the new employee orientations would have anywhere from 3 to 5 people at a time. But one summer (our slow period), we didn't need any more new employees, but they decided to hire a college student that was very popular and a member of the school rugby team. The guy was pretty hot looking, but he was dumb as a box of rocks. I think they hired him to attract customers to the store.
I went through the entire orientation process with him, and got to the part where he would get his new uniforms. I took him down to the storage closet, which was in the employee break room in the basement. I I usually tried to give the new employees a new unworn uniform if we had them, so I asked his size. I told him that the uniforms sizes were a little off, he would need to try the uniform to make sure it fit. I started to tell him to use the bathroom upstairs to try it on, but he asked if he could just try it on in the break room. I said that would be okay, and he locked the door to the breakroom while I searched for a new uniform. I found a shirt that should have fit him and I turned around to give it to him. I saw that he had already stripped off his shorts and t-shirt. He was just wearing his boxers, which were a little bit too small for him and the fly was wide open.
I turned around to get the pants and I couldn't find a new pair his size, but I did have a new pair that was a little bit smaller. I handed them to him and told him I wasn't sure if they would fit, but it was the only new pair I had. As he was trying on the clothes, I watched his body. He was about 5'10" and had 6pack abs, hairy chest and big muscular arms and legs. He tried the shirt on and said it fit fine. He took the shirt off and then tried to put the pants on. They were too small. So he took them off and I found a used clean pair in his size. He tried them on and they were a bit snug, but it did show off his ass. I asked if those were okay or he wanted to go up another size. He said they felt okay, but it was pinching his balls. And he grabbed his crotch to adjust. I found a pair a size up. He tried those on and they fit fine.
The entire time he was trying on the uniform, I got a great view of that open fly. A couple of times I got a glimpse of his soft cock and/or balls. Most of the time I just saw his dark pubic hair.
After he had worked there for a few weeks, he started dating a coworker who also happened to be a great friend of mine. One night we were out drinking and he admitted that he thought I was gay and thought it would be fun to give me a show during the orientation. I told him I did enjoy the show and we had a good laugh about it. He broke up with my friend a few months later and then quit his job shortly after that. My friend (his ex) later told me that he was pretty small, but I think she was just pissed off that he had dumped her.
