This story is pretty tame, but I think about it often as a real CFNM example:
I used to work for a company that had a number of employees with company vehicles. Not all were CDL drivers but the company insurance was pretty much the same for everyone, meaning we all had to get medical checkups to be on the driver list. There was one of those worker’s comp medical offices near the office that we all went to for the exam. Everyone complained about the hassle of the exam.
The exam was the same for everyone. After waiting to be called in, you completely disrobe and put on paper thin blue shirt and shorts. The doctor comes in and asks you some questions, takes your pulse, checks your heart beat and then has you get up to do some bends, stretches, and squats to check mobility. The final thing for everyone was always the dropping of the shorts for a very quick “turn your head and cough”. The shorts didn’t even come all the way off, you just stand there, pull them down and a gloved hand quickly presses near your junk. Then, it’s over.
