My sister in law (wife's brother's wife) has always been close to us. Closer then my wife's brother. She has stayed with us on vacation with the kids with out her husband and recently started telling us about marriage problems.

Normally she tells both me and my wife about the problems but a few weeks ago she starts texting me about how she is in counseling an is thinking about leaving him. When i asked my wife about it she had no clue about this. Then she starts texting me about how the sex has been bad and maybe she just needs a good lay on the side. Well i am no dumby i am going to fucking nail her so hard. She is Mexican and hot as hell and i know from texting she does anal (and my wife does not). So folks on her next visit i am literally getting Mexican ass! I can barely wait!
