I have been hooking up with my sisters father in law for a while off and on. He isn’t really attractive but he’s big and dominate and it’s always risky which is hot. No one knows we hook up. Last night my sister told me her monster in law (mother in law) was crying to her because she thinks he might be cheating on her. Even though she is a total b I still felt kind of bad for her. He told me a couple weeks ago he would leave her and we could be together. I do not want to be with him but I was like how would that even work? Your son is married to my older sister! I hope he didn’t leave her for me.
