Trip to see my Brother in law

I am taking a trip to hang with my brother in law. My husband and his sister are going on a trip to visit family but the brother in law and I did not get the time off. So I plan on going to visit him (in another state) and hang out with him. Had not had time to hang out alone with him in a while. His house is in a more country area where I could walk about the back door in my briefs and not care. But I will also spend time in the house around him in just my briefs too. If I pop a boner, oh well.
