My ex-wife and I have been divorced for almost 3 years. We have 3 kids together, and see each other a lot because of parenting obligations.

She's currently engaged to her "first love", the guy she met when they were like 12, and then dated until it was time to go off to college.

Anyway, I've still been fucking my ex-wife the entire time they've been back together. Sex was never one of the reasons she divorced me. We've pretty consistently kept our sex life going, even after he asked her to marry her, and continues still today.

So, here's the thing... the guy she's marrying is actually a really good guy. He's one of the most high character people probably that I've ever met. I'm actually starting to feel awful that I'm shoving my cock into his fiancée at least twice a week, and sometimes more; even if she is my ex wife. Every time I think about ending it, I just can't do it. I still really enjoy the sex. Clearly, she does, too.
