When I was 21 and working as a bartender, my wife was fucking my boss. He was mid-40s, married with kids. My wife was already fucking several guys, mostly friends of mine, with my full encouragement. I told her that I thought it would be hot if she seduced my boss.
She seduced him the first time on the couch in his office while I was there working. He fucked her in his office several times, then he started going to our apartment and fucking my wife while I was at work. He did not think that I knew he was banging my hot young wife.
After college, my wife and I worked in different departments at the same Fortune 500 company. Her boss was an older married guy. She seduced him too and they fucked regularly for a couple of years. He also did not think that I knew.
I love to eat used pussy, so I enjoyed eating the cum of my boss and her boss many times without them knowing.
