Like many of the other posters in this thread, I spent my entire adult life working as an engineering manager. I had both white collar employees (mostly white men). And blue collar employees (mostly Black men). I was on the timid side, and of course they saw my tiny white dick when we shared the men's room. However, I was the boss and I often had to chew them out when they fell down on the job. It was expected to have them resent me.
However, they all were "friendly" with my beautiful but slutty wife. She was a flirt all her life, and there was no hiding the fact that she loved other men, especially the Black alphas, to openly put the moves on her. It was commonly known that I was a failure both in the orgasms and baby-making departments. At company social events, Xmas parties, dinner/dancing events, pool parties, etc., she would flaunt her 37D-26-35 white charms. Men would bring her drinks and dance seductively with her. Eventually, she would be found in a dark, discreet corner with one of my Black employees groping her white teats or finger fucking her sopping wet married pussy. Like a good cuckold, I accepted my lot. I soon became acclimated to coming home from work and finding two or more of my employees fucking my wife and doing their best to impregnate her.
