I used to work in a job that required visits to sites in Africa every few months. To compensate for the work and distance, the small team of us (usually myself, her, and one other) would get put up in all inclusive 5 star hotels for the week or so we were there.

She was in her mid 40s, a director of the company, beautiful, well dressed, intelligent, formidable, married with kids. Typical white middle class life. She was a force to be reckoned with at work, didn't take shit from anyone, but at the end of the day she would have a few glasses of wine and a laugh.

She would also, after those few glasses of wine, start flirting with the staff and/or other guests. She would take a different man to bed with her every night.

I hope her husband isn't on here, but if he is: for years, every few months, she fucked a different man every night of every trip. .

Edit:

I stated this as a comment but wanted to add it because I see so many of the same comments again that I want to save you all time.

1: I didn't tell him at the time primarily because I did not feel comfortable and confident that sticking my nose in would keep my job and prospects of progression safe. Plus it's not like I ever had the opportunity. Also, as other comments have pointed out, I have no idea what their relationship dynamic is.

2: since leaving that job I have absolutely no means of contacting him, I've never met him, I don't even know his name. I have no idea about the details of their relationship, whether he knew about it, or what was causing her to do it. She has an almost non-existent digital footprint - it would take a lot of effort to track him down. But more importantly, I work in a very small professional world and I still feel I would be risking my career by getting a reputation for getting involved in what isn't my business.

If anyone wants to say I'm in the wrong or should care more or that I'm a coward then fine, go ahead, it's a free country, but I won't put myself in that position as I see it totally unnecessarily.
