Since my sister came back to town again we've been doing it a lot more. My wife and sister get along very well and after I found out they liked to lick each other's pussy when they met made me really want to have a threesome with them. I knew my wife didn't mind, the problem was how my sister would react to it. My wife said she will accept it with no problem. Well, I guess she was right because since she came back to life in our home town again I've been fucking both a lot more.
