Hell yeah this happened to me in work several times. I was working at the factory as a production worker, we were creating car parts. I was working at conveyor belt so I couldnt just go to bathroom whenever I wanted (only if somebody would switch with me). We had such hot handymen, those guys were sooo my type, tall dad bod and they loved to chat. Other guys were only younger warehouse boys, around my age (21), which I saw only 6 times a shift when they gave us material.
(not from my work but close)
Locker room was always like a heaven to me. The bulges, the asses, the musky smell. FUCK! I have strong clothes, underwear, socks fetish, so seeing them in just undies was so much better for me then seeing them naked. Sometimes I went on facebook and tried to find them but most of them dont have any pictures. But when they did, oh boy! I busted my nuts all over them.
One time I was totally falling asleep at my morning shift. And when I get sleepy I sometimes get horny. And this time I got extremly horny with raging boner. I couldn't help myself but to fantasize about guys who were constantly walking around me. Handymen had station behind me, so I could hear them talk in their sexy manly voices behind me, and smell their colognes mixing with their musks. My cock was totally pulsing, so I tried to calm it down but then I realized that noone can see it and its only thing that is keeping me awake.
So I started fantasizing about every guy who walked past me. One handyman walked past me. He was tall thick and had longer hair, which I love. I fantasized about him more then once before but only at home. At public it was diffrent but kinda hot. I imagined myself going with him to the mens restroom, our toilets were very nice and clean, it was joy going there. Anyways I would imagine myself touching his thick body over his clothes. Burrying my face near his musky armpit and then going down on his jean bulge. Then I would unzip his pants and burry my nose in his underwear under his balls. I would then turn him around and hump his ass while he is still wearing his undies. The image of me humping his ass was so hot that my cock was rock hard. I think I precumed a little. I would then pull down his undies and start fucking him raw till I would fill his guts up.

Then another handyman walked by. He was hot and had dark short hair and little scruff. I didn't like this guy that much cuz he was loud and obnouxious but he was still hot. I wanted to take him to restroom and skull-fuck his face to oblivion. Just imagining me face-fucking that big loud mouth of his was enough for my cock to start throbing. I would make him swallow my load with my cock still in his throat.
(loud handyman lookalike-he looks exactly like him)
Hour goes by and I have lost myself totally in my fantasies. Suddenly one of warehouse boys comes out and starts unpacking material. He is bending over like crazy and my eyes goes straight to his butt. He had the greatest cheeks I have ever seen. (picture at the end) He had red sweatpants on, in which you could see everything inside them. I was always peaking when he walked by me but this time I just stared and hoped noone will notice. I wanted to clap those cheeks so bad. When he walked away I started to fantasizing again. I imagined him in the same scenario as the long hair handyman. I would pull down his red sweatpants and play with his butt over his musky undies and then I would hump him. Then I would pull out my cock and cum on his butt while he is still wearing his undies and make him wear them till end of the shift.
(in my mind)
Finally it came time for me to go to bathroom. I rushed to bathroom and took a piss. My dick got little soft and while I was holding my cock I thought to myself:"should I jerk off?". I have never done anything like that in public before so I felt weird. But I went for it and started jerking off ruthlesly, but my dick didnt get hard cuz I was scared. So I stopped and took a deep breath but I was still horny as fuck and wanted to cum so bad. I needed to find some other way to get me hard. At least I know my weak spots, my fetishes. So I closed my jeans and pulled my cock through my zipper, it looked so hot to me. I started beating my meat and got instantly hard. Then I started thinking about how I would fuck that warehouse boy butt and all the things I would do to him. Needless to say I came in like minute. It was hottest thing I have ever done. I washed my hands and went to work like nothing happened. The adrenaline really woke me up and I wasn't feeling sleepy anymore and felt really good for rest of the day.
(not me but this is how it looked like exactly)
I started doing this for regularly if nobody was at the restroom, but sometimes when I heard footsteps I imagined it was one those hot guys and I came instantly. I also took my phone with me and jerked off to this picture of warehouse boy:

Anyways I need to jerk off, after this I got hard again.
