Spanking Chick In Vigorous Fetish Makeout

My wife is a ward sister and high flying NHS manager at our local hospital. We are both in our late forties now and enjoy some role playing games to help with our sexual excitement. We often meet up with another couple about 15 years younger and my wife's favourite experience is to dress up in her nurse uniform with black stockings and suspenders and be punished with a hard spanking and then given a good fucking by our friends. I often ejaculate over her face and would love to see her work colleagues watch her being used but unfortunately impossible at present.
