My sister-n-law and her husband came to visit us at the beach, and stayed in our guest house. Several days into their trip I walk outside to see Ali sitting in one of our hammock chairs. I reminded her that my wife was gone to her massage appointment, but she quickly let me know she wanted to talk to me. She began telling me that her husband was boring. Not only that, but she wanted to try anal. After discussion she wanted to do it now. With my wife away and her husband right above us on the next floor. My wife would be gone for a little over an hour. I didn't care about her husband Charlie. Who could resist a thick and tight virgin asshole? Of course I agreed I mean we aren't going to get caught, Right? Total POV
