My wife worked shifts at one point, which included a week of nights every 6 weeks, I would be up and gone when she got home. I knew she cheated before lots of times and she was into camming on public chat rooms so was horny as fuck. I have no evidence of her cheating but her interactions with some of the men she worked with at works outings made me think she had. I learned later they had 2 hours free in middle of the 12 hour shift. So she had time and options and she did tell me about some of the other women who fucked about.
Turns me on to think she did if honest.
