My best friend want to do this to my wife

I would prefer to have her over my lap and she must gently be supported.I would then lift her gown to above her bottom . She need not pull her buttocks open ,I will do that later. I will spank her with the back of a hairbrush until she indicates that she has accepted the punishment .She will then have her bottom massaged with some soothing cream.I will then gently part her buttocks with my thumb and forefinger so that her anus is clearly visible.She will adjust her position and make herself comfortable with her bottom up in the air so that I can gently start licking it. I hope she has a few little hairs around her anus ? Naturally while she is in this position I will very gently and lightly touch her cookie. After that she can take a well deserved rest. You may watch from a distance but you may not interfere.
