My wife and her best friend’s unique request- Part 1

My wife and I are in our late 40's and have been married for 19 years with two teenage children. We have a good relationship including the sexual aspects. My wife has a friend that she has known from her University days, they were more like sisters than best friends. Her friend lives not too far from us with her two children who happens to be twine. She lost her husband to road accident about five years ago and since then she has been devoted to her work (she happens to be a doctor) and her children. She

happens to be a very attractive woman and many a times I and my wife have tried fixing her with a date. But she is very timid and does not want a causal relationship because of her kids. We all normally meet for a family get together and outing with the whole family once a month. My wife and her friend were really close.

A couple of weeks ago I was in bed with my wife cuddling after we made love and she started telling me about her friend and how she hasn't had sex since her husband died five years ago! I mumbled something that she needs to find a boyfriend because she's young and a good person and deserves someone special in her life. That's when my wife asked me if I would have sex with her best friend. I was astounded. My wife and I are kind of vocal in bed and we're not shy about sharing sexual fantasies. She knew one of my fantasy was having sex with a close friend of ours. But I could not believe my ears as I turn to her and asked her to repeat what she just said.
