I think the wife fucking the boss, hers or his, is a fetish for many wives AND husbands. We have been friends for many years with several other couples whose wives all fuck other men (long story). We are all in some variation of cuckold/hotwife/stag-vixen relationships. All of the wives in our group of friends have fucked more than one of their bosses or their husbands bosses during their marriage. The wife of one of the couples has fucked every boss she has worked for and in some situations her boss's boss.
I think it is really hot that my wife Kate has been fucking her married boss for years. I have owned our company for many years so I don't have a boss, but Kate has had sex with a guy who was working for me at the time and a couple of my business associates.
