My dad used to get thrown p*ssy at his work all the time. I even saw it in real life myself. He always refused (or so he says). When he was on his deathbed he finally told me why he resisted. He said that he found a woman who had his back, loved & respected him and looked after him.
Your dilemma is simple. Is fukking this woman worth risking your wife, kids and job for? Only you can answer this question.
Great points and props to your dad.
