Many accounts of F/M spanking start with the Mother giving her daughter a hairbrush to ensure the husband stays in line. It is normally mentioned that the Mother spanked her husband and that the tradition is being continued. Mom sometimes witnesses the spanking and also spanks the S-I-L.
I wonder how common this is in the real world. I am thinking it is exceedingly rare. I guess the only way to find out would be to do a house-to-house canvas looking for wood hairbrushes.
