This guy invited me to a concert before covid.

We went with some of his friends coworkers he had a older married female coworker they said they were going to look to get gifts me and her husband stayed back, I had to pee so I left. I saw them go in a Urinal together! The guy and the married coworker.

They said that they peed together she sat all the way back left a hole in the toilet seat where he aimed peed at the same time and I know they really had to urinate so I believe they did that but isn't that disgusting or considered cheating he saw her vagina and she saw his dick in her face who knows if they had sex that time.

They hang out smoke together she is middle age he's in his early twenties this shit is disgusting she's cheating on her husband right?

But peeing together is disgusting

They were waiting in line to go use the urinals it was a long line but he could of used the urinal right after her why go at the same time that seems suspicious and gross.

What would you guys have done?
