Wife’s BFF

A few years ago my wife said to me if I go first you have my blessing to move on with another woman, only I ask it’s not with xxxxx her best friend.
Right now her best friend is downstairs and all I can think of is playing with her big beautiful breasts, putting my cock in her mouth and then turning her over to slide between her tight ass cheeks deep into her pussy.
I know it’s wrong but right now I’m so freaking horny for that body.
