While I have sex with my wife, she tells me that she would like to see me fucking her best friend

One morning while we were resting on the farm I heard my wife watching some apparently pornographic videos... After a few minutes she goes to the kitchen for something to and I take the opportunity to check her phone... I realize that her best friend KourtneyLove sent her some videos of her masturbating, of course I got really horny because her best friend is hot... She discovers me and approaches me telling me that one of her biggest fantasies is to see me fuck her best friend... We had Incredible sex while we talked about how she would penetrate her best friend's pussy!!
