I had told you in my previous question about my widowed SIL. My Wife had agreed to me having sex with her, after I found out about they both having a Lesbian relationship.

At first my wife denied but then she accepted that she had lesbian sex with my SIL. Later my wife told me that she did not want to continue with her as she was not having interest. I had jokingly told her that I will take her place and satisfy my SIL. At first she was angry. But later agreed.

Now, I am having wild sex with my SIL. So, what is the problem? The problem is that my wife has become jealous. My SIL allows me to fuck her, whenever we are alone at home. I told my SIL that we should have 3 sum together with my wife. But my SIL is not ready for that.  

I am condused and worried my future sex life. What to do?

I am 29 years old and my SIL is 35 years old.
