My wife and I have a friend who visits about 4 times a year and stays for the weekend. I'm not much into spanking myself but love watching our friend spank my wife. He's very dominant and she must call him Sir and when she's being spanked she has to call out the number and thank him. If she gets anything wrong he starts over. On occasion, when she's really horny, she'll purposely make a mistake so he'll spank her more. His cock is about 8" long and very thick and she takes a lot of it over the weekend. Sometimes I just watch, other times I play the cuck and also do as I'm told. They are always very interesting and erotic weekends.
