My wife use to fuck a co worker on work trips.I only found out after by seeing a text on her phone,First she had to go to seattle for work and he did as well which ebemtually led to hooking up.After a while if she had to go somewhere alone he would take time off work and secretly go and she did the same.work sex does happen more than you think.
I used to have a job where it was my role to train people to use the company’s proprietary software when we traveled for work all over the country and the vast majority of the new hires that I would help train were women. Well, when you are bored and young in these places in the middle of nowhere and you only know one person and spend a lot of time with them you tend to get close and that leads to sex. I probably fucked at least twenty or so coworkers in my time there, almost all of them had a bf or husband
